Safety while using Internal Combustion Engines
There are dangers while operating or refueling the internal combustion engine. Serious
damage may be led if the safety regulations described as follows are not obeyed.
SAFETY LABELS
Cutting machine used international generic icon labels, as follows:
Label
Meaning
Warning! To prevent hearing loss, in the
operation with good hearing protectors.
Harm! The engine of carbon monoxide released
only in a well-ventilated the operation. Reading
a manual, sparks or flame of burning. Increase
fuel engines to be shut down.
Gasoline fuels.
Attention! In the operation of the machine, read
and understand the manuals provided by the
operator. Otherwise, I will hurt or harm others.
Turn the engine off before refueling.
Warning! HOT surface.
Do not put hands into the rotating cutter blades
。

When cutting, the machine can not have road
blocks and other former obstacles
OPERATION
1. The oil level check
Put dipstick into the oil port, do not rotate, take out to check oil level, if the engine oil level
is low add oil to the recommended upper limit at the dipstick.
2. Air Filter
Check the air filter element, ensure it is clean and in good condition. If necessary, clean or
replace components.
3. Fuel
Recommended use of gasoline engines. Prohibit the use of oil / gasoline mixture or dirty
gasoline; avoid dirt, dust or water to get the fuel tank. Caution: prohibit the use of gasoline
alternatives; they are harmful effects of fuel system components.
Cutting machine operator
1. Start the engine, load 3-5 minutes, then transferred to the appropriate location of the
throttle.
2. Rotate the hand wheel to slow down the blade to the desired depth of cut (cutting
machine in this model the depth range), rotary drive up stopper, the cutting depth lock.
Slowly push the machine for cutting.
Fitting the blade
Set he machine in the high position
Swift off (A); disconnect the water pipe from the blade guard.
Lift up guard (B) (FIG. 1)
Take care about the direction of rotation which is shown by an arrow on one of the faces
(direction of rotation on the right side of the guard) Make sure the contact faces of
flanges (B and C) of blade and the axle are clean.
Firmly lock screw using the spanner supplied with the machine whilst immobilizing the
blade by hand. (C)
Replace the protection guard (B).
Close the guard water tap. (A)
Reconnect the water pipe.
Replace all protective covers for your safety and that of other persons. Note: how to adjust the
‘zero’ according to the diameter of blade:

Check before starting
The blade must be closed to the floor.
Loosen the screw (D) (FIG 2)
Line up the ‘zero’ with the pointer, then tight the screw.
FIG 2
FIG 1
Danger: risk of injury.
Always pay extreme care and attention to the preparation of the machine before
starting up.
Remove all adjustment tools and wrenches from floor and machine.
Always keep blade guard in place.
Fill the tank with water, or connect with the water network.
Mark the floor by drawing a line in the place to be cut.
Fold down the front guide and position the machine so that the guide and the
blade line up with the mark.
Engine:
Starting the engine: refer to the instructions in the manufacturer’s service manual.
a) Open the water inlet tap.
b) Increase the engine speed to maximum.
c) Lower the blade to the desired depth indicated on the side scale on the ratchet placed
on the side. We recommend a slow descent to avoid stalling the engine.
Note: ensure that the water supply is abundant, when cutting wet.
Stopping the machine
a) Low the black wheel and turn the wheel to release the blade from the groove.
b) Turn off the water supply
c) Allow the engine to turn at low speed

Starting Up
Stop the engine (consult the engine maintenance manual)
Maintenance
‘Engine Maintenance’: refer to the engine maintenance booklet.
a) After use, clean the machine.
b) Lubrication: apply a moderate amount of bearing lubricant to the nipples in the
depth adjustment chassis (depending on the frequency of use)
c) The spindle bearings must be greased after 8 hours of use, with a grease gun by
pumping three to five times the grease into the greaser of the bearings.
d) Every 40 hours grease: depth control adjustment screw.
‘Air Filter’
a) Read engine owners manual for maintenance intervals. For extremely dusty
conditions you may have to clean the air filter element 2 to 3 times a day.
b) Replace any damaged filters or gaskets.
Store in a safe place out of reach of children
Remove all adjustment tools and wrenches.
Store diamond tool in a safe place so it cannot be bent or damaged.
Motor Belt Tension
After several hours of use it may be necessary to adjust the tension of the belts
(moderately). To do these proceed as follows:
a) Release the screws fixing the motor to the chassis.
b) Turn the tensioning screw (E) at the front of the machine one quarter turn; this screw
pushes the motor backwards. (FIG. 3)
c) At normal tension, counter lock the nut of the screw.
d) Relock the motor fixing screws.
Note: never set belts beyond original tension.
FIG 3
5
Important Recommendations
a) Periodically tighten all nuts and bolts, particularly after the first few hours of
operation.
b) Check the tension of the belt, tighten it as instructed
c) When storing the machine, we recommend removing the blade and storing it carefully
d) Check that the blade is properly sprayed by inspecting the holes in the fork regularly
e) Tighten the blade firmly
f) Make sure the contact faces of flanges, blade and axle are clean. The manufacturer
declines all responsibility for loss or damage resulting from misuse or any modification,
alteration or powering that does not conform to the manufacturer’s original specifications.
Cutting Machine Caution:
1. Start the engine before the switch to open flame, go to the fuel valve open (ON)
position, place the throttle closed (Close) position (Note: If the state of the engine as
heat or high temperature, the engine starts to throttle open). After the engine starts,
slowly move the throttle open (OPEN) position.
2. Before you start the engine, cutting blade should be removed from the ground, after
the engine runs, adjust lower in the slowly toward the cutting depth, then lock the
cutting depth. Avoid rapid downward adjustment cutting depth
3. the depth of each cut should be determined according to the actual cutting conditions
on the ground, the different hardness of the ground effect for this model is also
very important, the higher the hardness of the depth of a cut should be smaller,
while the road speed of the machine should slow down, Order to be conducive to the
efficient work of cutting machine
4. if cutting depth too deep, the engine emits unusual sounds, machinery easily to
cause injury, the operator has a security threat, then raise the blade should be timely to
re-adjust the cutting depth
5. Once cutting blade does not cut capacity should be worn out replace them with
new cutting discs, continue using the old blade will damage the blade shaft and other
components, severe fracture, cutting blade will break
6
6. After each use, clean the cutting machine in a timely manner, in accordance with
the maintenance and maintenance methods, please do not use fatigue
7. prohibited people (two and above) operating the same cutting machine, the
machine work in order to avoid confusion and unnecessary harm

3. Clean or replace air filter
4. Check both sides of the blade shaft bearings for wear, damage, or grease (oil)
less than
5. In the cold season, warm the engine idle for 3-4 minutes
Check belts for wear, damage, or not enough tension
The engine is running but
with poor result
1. Check the cutting blades wear
2. Check the tension of belt

d) To position the floor saw on the site, simply push it. It will move easily on its four
wheels without starting the engine.
e) For transporting by vehicle or by any kind of lifting gear, there is a factory-fitted
hoisting point on the machine.
STORAGE
If the milling machine storage more than 30 days:
1. Replace the engine oil.
2. Drain the fuel from the engine.
3. Remove the spark plugs, the 1 / 2 oz (15ml) of SAE30 engine oil poured into
the cylinder. Spark plugs installed, turn the engine to make the oil spread. See engine
manual.
4. Clear cylinder, cylinder head heat sink, flywheel cover, rotating screen and muffler
area of dust.
