SAFETY
• Keep work area clean, free of clutter and well lit.
Cluttered and dark work areas can cause accidents.
• Do not use your sawmill where there is a risk of causing
a fire or an explosion; e.g. in the presence of flammable
liquids, gasses, or dust. Power tools create sparks,
which may ignite the dust or fumes.
• Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control,
so visitors should remain at a safe distance from the
work area.
• Be aware of all power lines, electrical circuits, water
pipes and other mechanical hazards in your work area,
particularly those hazards below the work surface
hidden from the operator's view that may be uninten-
tionally contacted and may cause personal harm or
property damage.
• Be alert of your surroundings. Using power tools in
confined work areas may put you dangerously close to
cutting tools and rotating parts.
WARNING: Internal combustion engines present special
hazards during operation and fueling. Read and follow the
warning instructions in the engine Owner's Manual and
the safety guidelines below. Failure to follow the warn-
ings and safety standards could result in severe injury or
death.
• DO NOT run the machine indoors or in an enclosed area
such as a deep trench unless adequate ventilation,
through such items as exhaust fans or hoses, is provid-
ed. Exhaust gas from the engine contains poisonous
carbon monoxide gas; exposure to carbon monoxide can
cause loss of consciousness and may lead to death.
• DO NOT smoke while operating the machine.
• DO NOT smoke when refueling the engine.
• DO NOT refuel a hot or running engine.
• DO NOT refuel the engine near an open flame.
• DO NOT spill fuel when refueling the engine.
• DO NOT run the engine near open flames.
• ALWAYS refill the fuel tank in a well ventilated area.
• ALWAYS replace the fuel tank cap after refueling.
• ALWAYS check the fuel lines and the fuel tank for leaks
and cracks before starting the engine. Do not run the
machine if fuel leaks are present or the fuel lines are
loose.
• ALWAYS avoid contact with hot fuel, oil, exhaust fumes,
and hot surfaces.
• Stay alert. Watch what you are doing and use common
sense when operating a power tool. Do not use a power
tool while you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention while
operating power tools may result in serious personal
injury.
WARNING: Read and understand all
instructions. Failure to follow all instruc-
tions listed below may result in electric
shock, fire and/or serious injury.
WARNING: The warnings, cautions, and
instructions discussed in this instruction
manual cannot cover all possible condi-
tions or situations that could occur. It
must be understood by the operator that
common sense and caution are factors
which cannot be built into this product,
but must be supplied by the operator.
WARNING: Only operate the engine in a
well ventilated area. Carbon Monoxide
produced by the engine during use can
kill. Do not use indoors, near windows or
in other sheltered areas.
NOTE: All Federal and State laws and any
regulation having jurisdiction covering
the safety requirements for use of the
machine take precedence over the state-
ments in this manual. Users of this
machine must adhere to such regulations.

SAFETY
• Dress properly. Do not wear loose clothing, dangling
objects, or jewelry. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewelry or long
hair can be caught in moving parts. Air vents often cover
moving parts and should be avoided.
• Use safety apparel and equipment. Use safety goggles
or safety glasses with side shields which comply with
current national standards, or when needed, a face
shield. Use a dust mask in dusty work conditions. This
applies to all persons in the work area. Also use
non-skid safety shoes, hard hat, gloves, dust collection
systems, and hearing protection when appropriate.
• Do not overreach. Keep proper footing and balance at all
times.
• Remove adjusting keys or wrenches before connecting
to the power supply or turning on the tool. A wrench or
key that is left attached to a rotating part of the tool
may result in personal injury.
• Never make blade guide adjustments, remove or install
blades or conduct any other maintenance or make any
other adjustments when the engine is running. Always
shut the engine off, remove the ignition key, and keep
the engine off before carrying out any of the aforemen-
tioned procedures. Consult your engine manual for safe
shutdown procedures to prevent accidental ignition.
• Always be sure operator is familiar with proper safety
precautions and operation techniques before using
machine.
• Never touch the engine or muffler while the engine is on
or immediately after it has been turned off. These areas
get hot and may cause burns.
• Always close fuel valve on engines when machine is not
being operated.
• Avoid "kick-back” by knowing what conditions can
create it.
• Do not force the tool. Tools do a better and safer job
when used in the manner for which they are designed.
• Never use the sawmill with a malfunctioning switch or
throttle. Any power tool that cannot be controlled with
the switch is dangerous and must be repaired before
using.
• Turn off the engine and place the switch in the locked or
off position before servicing, adjusting,installing acces-
sories or attachments, or storing. Such preventive
safety measures reduce the risk of starting the power
tool accidentally.
• Secure logs with the log screw clamping device instead
of with your hand or another someone else's help. This
safety precaution allows for proper tool operation using
both hands.
• Storing sawmill. When the sawmill is not in use, store it
in a dry, secure place or keep well covered and out of
the reach of children. Inspect the sawmill for good
working condition prior to storage and before re-use.
• Maintain your sawmill. It is recommended that the
general condition of the sawmill be examined before it
is used. Keep your sawmill in good repair by adopting a
program of conscientious repair and maintenance in
accordance with the recommended procedures found in
this manual. If any abnormal vibrations or noise occurs,
turn the sawmill off immediately and have the problem
corrected before further use.
• Keep saw blades sharp and clean. Properly maintained
bandsaw blades are less likely to bind and are easier to
control.
• Cleaning and Lubrication. Use only soap and a damp
cloth to clean your sawmill. Many household cleaners
are harmful to plastic and rubber components on the
sawmill.
• Use only accessories that are recommended by the
manufacturer for your model. Accessories that may be
suitable for another sawmill may create a risk of injury
when used on the SM26 sawmill.
• Always operate machine with all safety devices and
guards in place and in working order. Do NOT modify or
make changes to safety devices. DO NOT operate
machine if any safety devices or guards are missing or
inoperative.
• Never leave sawmill running unattended.
• Coiled blades can spring apart with considerable force
and unpredictably in any direction. Always deal with
coiled blades, including those packaged in boxes, with
the utmost care.
• Never use the equipment to cut anything other than
lumber or for any purpose other than cutting lumber as
described in this manual.
TOOL USE AND CARE

SAFETY
• Wear heavy-duty work gloves, ANSI-approved goggles
behind a full face shield, steel-toed work boots, and a
dust mask.
• Operate only with assistance.
• Ensure guide blocks are tight and track is level
• Fill the lubrication tank with clean water and dish soap.
• Start and operate the engine according to the provided
engine manual.
• Depress the throttle to bring the blade up to full speed.
• Throttle should be fully depressed when the saw is
under load.
• Cut branches off the lumber to be processed.
• WARNING: To avoid death or serious injury. Do not cut
lumber with foreign objects in it such as nails, any
metal pieces, etc.
• Place the lumber to be cut on the supports.
• WARNING: The operator and any assistants must stay
clear of the front and back of the blade whenever the
engine is on.
• Move the saw head slowly along the track and against
the lumber to make the cut.
• Trim off the rounded sides of the log.
• When the log is squared-off, boards or posts can be cut
to custom specifications.
• To prevent accidents, turn off the engine and discon-
nect its spark plug wire after use. Wait for the engine to
cool, clean external parts with a clean cloth, then store
the equipment out of children's reach.
4. Log Screws—Grease frequently.
5. Belts-Periodically check the condition and wear of the
drive and idler belt. Ensure that the blade does not ride on
the band-wheels.
6. Drive Belt—Periodically check the tension of the drive
belt. It should deflect by no more than 1/2".
7. Saw-Head Locking Cam Handles—Grease assembly
every 30 days or as required.
8. Saw-Head Vertical Posts—Spray posts before use with
a silicone spray lubricant such as 3in or Jig-A-Loo.
9. Bandwheel Guards—Routinely remove any build-up of
sawdust that may collect inside the bandwheel guards.
10. Lubrication Tank-Only fill with a water/dish soap
mixture(one to two caps) or in winter months, use wind-
shield washer fluid. Do not leave lubricant in tank if
temperatures fall below 0°C (32°F).
Proper and routine maintenance is critical to operator
safety, achieving good milling results and to prolonging
the life of your investment.
1. Band wheel Bearings—Should be inspected before use
to ensure they are not worn. Bearings are sealed and do
not need to be greased.
2. Blade Guide Bearings—Inspect before use for exces-
sive grooves or scoring in the bearing case. Replace if
necessary.
3. Blade Tension—Grease threads of tensioning "T"
handle when dry or as required. Use multipurpose,
extreme-pressure grease.

ASSEMBLY
During several of the assembly steps, more than one socket or wrench of the same size may be required to assemble the
hardware. A socket or box wrench in combination with an adjustable wrench can be utilized if multiple same size tools
are in limited supply.
Assemble the track with the provided components and hardware listed in the table below. It is important to assemble and
level the track on a firm foundation before tightening all of the hardware and should ideally be 3.5–4 in [90—100 mm] off
the ground. This will allow for easy cleanup of sawdust and log support height adjustments.
When assembling the sawmill, do not torque the bolts to hardware Class/Grade specifications. Snug
the hardware, then tighten a further ¼—½ turn. Tightening bolts to torque spec can crush metal
tubing, ruining the components.
Assemble one of the bunk assemblies over the joint between both pairs of track rails using the components and hardware
listed in the table below.

First, set the four (4) track rails on top of four pieces of lumber of equal height. It is ideal to keep the rails at least 4-6 in
[100-150 mm] off the ground for ease of assembly.
Next, assemble the bunk assembly over the rail joints with a reinforcement plate under the rails on both the left and right
sides. Use eight M10 X 30 mm flanged hex bolts and M10 flanged lock nuts per side.
Keep the outer faces of the rails 2 ft 7 in apart but do not fully tighten the hardware. Snug the bolts enough so that minor
adjustments to the track width can be made once all the bunks are assembled to the rails.
Build track up off the ground
on large timbers or blocks for
ease of assembly, preferably

MID & END BUNKS
SQUARING THE TRACK AND SETTING THE WIDTH
Use M10 X 30 mm flanged hex bolts and M10 flanged lock nuts at all end & mid bunk locations. Snug the hardware in the
same manner as the center bunk.
With the bunk hardware connections only snug-tight, the rails can be moved in or out as needed until the proper width is
achieved along the entire length of the track.
Once the width is correct and the rails are square, tighten
all M10 x 30 mm flange hex bolts and their nuts, working
from the center toward the end, as shown above with the
black arrow. Check the width and square of the track
again after tightening. Readjust if necessary.
Ensure the end bunks are square to the rails.
END BUNKS SQUARE TO RAILS
When the width is uniform along the full length of the track, check its square by measuring diagonally from corner to
corner of the track rails.

Attach the (12) leveling feet assemblies to the rails at the locations shown below.
Assemble the leveling feet up through the bottom of the guide rail and thread the M16 hex nut to each foot. Do not tighten
the nut. Leave it loose enough so that there is a noticeable gap between the nut and the track to allow the track level in
later steps.
With the feet loosely assembled to the rails, remove the timber/block supports so the full weight of the track is resting
on middle nuts of the leveling feet.
Turn the middle nut on each foot to fine-tune the level. Once level, secure each foot to the rail by tightening the M16 top

Please Note: We recommend adding some dishwashing liquid to the tank to help lubricate the wood - two to three
capfuls.
Add waterproof grease to the threads of the blade tension “T” handle and to the washer face that it meets before use.
Proper blade tension is achieved when the blade deflects no more than a total of 1/8” - 1/4” up/down.
22
www.mechmaxx.com
ASSEMBLY
*Note – It is very important to release the blade tension
by turning the “T” handle in the counter-clockwise
direction when the sawmill is not in use. Failure to do so
will result in flat spots on the rubber belts. These flat
spots will cause the mill to vibrate excessively during
next use.*
Push the saw head up and down the track system to ensure that the width of the track allows for the saw head to move
freely. If it binds, the "L" rails will need to be set further or closer together to achieve a consistent width along the entire
track system. Once the desired width is achieved, all nuts and bolts can be tightened on the log bunks
Add waterproof grease to all “ ” handle threads on the sawmill.
23

ASSEMBLY
Using a tape measure, take a measurement from the blade to the top of the log bunk on both the left and right sides. The
distance should be equal on both sides. If it isn't, you will need to adjust the cable ends at the rear handle to either raise
or lower one side.

Refer to the engine manual before using your sawmill.
Please note that the engine does not contain any gasoline
or engine oil when it is shipped. Furthermore, the engine
is equipped with an oil alert system, meaning that if the
crankcase oil level is low or empty, the power is cut to
the spark plug and it will not start.
Always cut in the direction shown above. The log clamp should always be on the right side of the log and the log supports
should always be on the left. Failure to cut in this direction can cause the log to come loose and possibly even cause
damage or injury.
*Now that your sawmill is assembled, please run through the “SAWMILL SET-UP PROCEDURES” in the following section.
Failure to do so may result in poor sawing performance, damage or injury. See next page.*

SAWMILL SET-UP PROCEDURES
To check the belt tension, with your hand, firmly try to
deflect the belt up and down. There should be no more
than 1/4” of deflection in both directions (1/2” total). If
the belt deflects more than this, it will need to be tight-
ened as described below.
To tighten the drive belt, start by loosening the four bolts
that secure the engine to the engine mount using a
16mm wrench.
Now that the engine is free to slide on the engine mount-
ing plate, turn the 16mm nut on the horizontal stud in the
clockwise direction. This will pull the engine toward the
stud and apply more tension on the belt. Do this step
incrementally while checking the belt for proper deflec-
tion. It is also important to ensure that the engine
remains perpendicular to the drive belt. Overtightening
can cause the engine to twist on the mounting plate,
resulting in belt alignment issues and premature wear.
Once the desired belt tension is set, tighten the four
engine bolts. Alternatively, if the drive belt is too tight,
the 16mm nut on the horizontal stud can be turned count-
er-clockwise.
Never attempt the following steps with the engine running. As a
safety precaution, remove the spark plug cap. It is also
advised to wear gloves and safety glasses when working
with the blade as it is extremely sharp.

the distance from the tip of the blade tooth to the front
face of the bandwheel on both sides. If an adjustment on
either side is required, the following steps will detail this
procedure.
Loosen the blade guide assembly bolt with a socket. The
round shaft should now be free to slide rearward and out
of the way. Perform this step on both guide assemblies.
This will ensure that the guide bearings do not influence
tracking of the blade while adjusting.
Take some tension off of the blade by turning the "T"

more rearward on the bandwheel, this bolt will need to be
turned clockwise. Alternatively, turning the bolt in the
counter-clockwise direction would force the blade to run
more forward on the bandwheel. Turn the bolt half a turn
the blade.
ADJUSTING THE LEFT HAND SIDE
3/8”
Wearing gloves, spin the bandwheel with your hand and
observe how the blade has changed tracking. Measure the
distance again and repeat the steps above to further
compensate if required.The ideal measurement is 3/8”.
To adjust the left side of the sawmill, again start by
taking the tension off of the blade by turning the “T”
handle one turn in the counter-clockwise direction. Using
a 16mm wrench, loosen the “vertical nut” a ½ turn. Do
the same on the “bottom vertical nut”. Next, loosen both
“vertical bolts” a ½ turn. This will take the clamping force
off of the bandwheel shaft caused by these two bolts and
allow it to move freely in the following steps.
Once satisfied with the measurement, tighten the locking
nut clockwise.

MOVING THE BLADE FORWARD
BLADE GUIDE ADJUSTMENT
Once the blade is tracking true, bring the blade guide
assemblies back up to the blade. Maintain a gap approxi-
mately the thickness of a piece of paper between the
blade guide bearing and the back of the blade. More
information on this setup can be found in the next
section – ”BLADE GUIDE ADJUSTMENT”
Re-tension the blade by turning the “T” handle a full turn
in the clockwise direction. Wearing gloves, spin the band-
wheel with your hand and observe how the blade has
changed tracking. Measure the distance again and repeat
the steps above to further compensate if required. The
ideal measurement is 3/8”.
Never attempt the below with the engine running. As a
safety precaution, remove the spark plug cap. It is also
advised to confirm that the blade is tracking properly
before performing the below. Blade tracking is covered in
the previous page.
Using a 6mm Allen key, loosen the blade guide blocks on
both the left and right sides. They should be free to slide
up and down.
Using a 16mm wrench, hold the “horizontal bolt” station-
ary with a wrench and turn the “horizontal outside nut”
counter-clockwise a ½ turn. Still holding the “horizontal
bolt” stationary, turn the “horizontal inside nut” clock-
wise a ½ turn. This step has now shifted the “horizontal
bolt” and bandwheel shaft, causing the blade to track
more forward. Tighten the vertical bolts, then nuts to
clamp the bandwheel shaft back into its vertical position.

SAWMILL SET-UP PROCEDURES
BLADE TENSION
Loosen the blade guide assembly bolt with a 16mm
socket. The round shaft should now be free to slide back
and forth. Position it so that there is a gap approximately
the thickness of a piece of paper between the bearing
and the back of the blade. Tighten bolt against the flat on
the shaft to secure assembly back in position.
Adjusting the gap above the saw blade.
Adjust the gap below the saw blade.
Using a piece of paper in between the blade and blade
guide blocks, tighten the Allen key bolts.
Proper blade tension is achieved when the blade deflects
no more than a total of 1/8” - 1/4” up/down when it is
firmly moved by hand at the center location of the blade
guide blocks. Turning the blade tension “T” handle in the
clockwise direction will add tension to blade.

SAWMILL SET-UP PROCEDURES
When tensioning the blade, make sure the tracking
adjustment bolt sitting behind the T handle (pictured) is
sitting back in its recess after you have finished and
before the mill is run. Failure to do this will result in the
blade being thrown and possibly broken.
Tracking adjustment bolt out of recess. If it looks like
this DO NOT start the mill until it is resting back in its
recess
Tracking adjustment bolt sitting in recess. It should look
like this before the mill is started back up.
Ensure the blade support arm is locked into place after
tensioning the blade.

CHANGING THE BLADE
REPLACING BELTS
SAWMILL MAINTENANCE
Never attempt the below with the engine running. As a
safety precaution, remove the spark plug cap. Gloves and
safety glasses must be worn when changing the blade.
There are two rubber "V” belts on the sawmill and they
should be replaced as a set. It is not advised to replace
individual belts separately. It is recommended to use a
BX77 cogged belt for the drive side and a BX58 follower
belt.
Remove the tension in the blade by turning the “T” handle
in the counter-clockwise direction and then open the
blade guard cover. The blade should now be loose and free
to pull straight out the front. The new blade can now be
installed, guards closed and proper blade tension set.

SAWMILL MAINTENANCE
The follower belt can now be changed by simply pulling it
off and installing the new one. The blade can now be
reinstalled, guards closed, and proper blade tension set.
*Note that blade tracking is likely to change and needs
adjusting when new belts are installed. Refer to “BLADE
TRACKING” for more information.*
Now that the engine is free to slide on the engine mount-
ing plate, turn the 16mm nut on the horizontal stud in the
counter-clockwise direction. This will allow the engine to
move and will also take the tension off of the belt. The old
belt can be removed and the new belt can be installed.
Tension the new belt and refer to the BELT TENSION
instructions described in the sawmill setup section of
the manual.
