LAWN MOWER SAFETY
II SLOPE OPERATION
Slopes are a major factor related to slip and fall accidents,
which can result in severe injury. Operation on all slopes
requires extra caution. If you feel uneasy on a slope, do not
mow it.
1. Mow across the face of slopes; never up and down. Exer-
cise extreme caution when changing direction on slopes.
2. Watch for holes, ruts, bumps, rocks, or other hidden ob-
jects. Uneven terrain could cause a slip and fall accident. Tall
grass can hide obstacles.
3. Do not mow on wet grass or excessively steep slopes.
Poor footing could cause a slip and fall accident.
4. Do not mow near drop-off s, ditches, or embankments. You
could lose your footing or balance.
III. CHILDREN
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the ma-
chine and the mowing activity. Never assume that children will
remain where you last saw them.
1. Keep children out of the mowing area and under the watch-
ful care of a responsible adult other than the operator.
2. Be alert and turn mower off if a child enters the area.
3. Never allow children to operate the machine.
4. Use extra care when approaching blind corners, shrubs,
trees, or other objects that may block your view of a child.
IV. SAFE HANDLING OF GASOLINE:
To avoid personal injury or property damage, use extreme care
in handling gasoline. Gasoline is extremely fl ammable and the
vapors are explosive.
1. Extinguish all cigarettes, cigars, pipes, and other sources of
ignition.
2. Use only an approved gasoline container.
3. Never remove gas cap or add fuel with the engine running.
Allow engine to cool before refueling.
4. Never refuel the machine indoors.
5. Never store the machine or fuel container where there is an
open fl ame, spark, or pilot light such as on a water heater or
on other appliances.
6. Never fi ll containers inside a vehicle or on a truck or trailer
bed with a plastic liner. Always place containers on the ground
away from your vehicle before fi lling.
7. Remove the mower from the truck or trailer and refuel it on
the ground. If this is not possible, then refuel the mower with
a portable container, rather than from a gasoline dispenser
nozzle.
Continued,
8. Keep the nozzle in contact with the rim of the fuel tank or
container opening at all times until fueling is complete. Do not
use a nozzle lock-open device.
9. If fuel is spilled on clothing, change clothing immediately.
10. Never overfi ll fuel tank. Replace gas cap and tighten
securely.
V. GENERAL SERVICE
1. Never operate the mower in a closed area.
2. Keep all nuts and bolts tight to be sure the mower is in safe
working condition.
3. Never tamper with safety devices. Check their proper
operation before each use of the mower.
4. Keep the mower free of grass, leaves, or other debris build-
up. Clean up oil or fuel spillage and remove any fuel-soaked
debris. Allow machine to cool before storing.
5. If you strike a foreign object, stop and inspect the mower.
Repair, if necessary, before starting.
6. Never make any adjustments or repairs with the engine
running. Disconnect the spark plug wire and ground against
engine to prevent unintended starting.
7. Never attempt to make wheel height adjustments while the
engine is running.
8. Check grass catcher components and the rear discharge
door frequently and replace only with Bad Boy original parts
when necessary.
9. Mower blades are sharp. Wrap the blade or wear gloves,
and use extra caution when servicing them.
10 Do not change engine governor setting or over speed the
engine.
11. Maintain or replace all safety and instruction labels.
CAUTION
Muffl er and other engine parts become extremely
hot during operation and remain hot after engine
has stopped. To avoid severe burns on contact,
stay away from these areas.

CONTROLS & OPERATION
Before operating the mower for the fi rst time, please review
and understand the entire manual including all Warnings and
Cautions.
Even if you have operated other mowers in the past please
take time to become familiar with how this mower works and
practice all operations to build up your skills.
BEFORE ANY OPERATION ALWAYS:
- Inspect the mower for any visible damage or broken parts
- Check the oil level in the engine
- Make sure that when you release the upper control bar
that the blade will disengage and stop. If it does not stop
immediately do not use the lawn mower until the problem has
been corrected. Contact your authorized Bad Boy dealer.
- Never operate the mower with obvious damage or
malfunction until the problems have been corrected.
WARNING
Never make any adjustments or repairs with the
engine running. Disconnect the spark plug wire,
and keep the wire away from the spark plug to
prevent accidental starting.
STARTING THE ENGINE
To start a cold engine it is important to use the “Choke”
position. To start a warm engine it is not necessary to use the
choke.
For best performance use the “Full Throttle” position for all
mowing. To verify that the engine is running at full throttle
please follow the steps outlined under the set up instructions
- Step 9 on Page 9.
A Bad Boy dealer can typically also verify the correct full
throttle adjustment. The engine speed should be approximately
3600 RPM without the blade engaged (no load).
BLADE CONTROL - BBC (Blade Brake Clutch)
It is a two step process to engage the blade. Do not start the
engine and the blade on an uncut lawn. If the blade is blocked
by tall grass or debris it can damage the belt drive between the
engine and the blade during the engagement.
1. Start the engine and let it warm up for 10 to 30 seconds.
2. Set the throttle control to the “Full Throttle” position.
3. Push the lock (1) for the upper control bar to the side.
4. Push down on the upper control bar until it rests on the
handlebar (2). You will distinctly hear the blade operating -
making a fan like noise.
5. When the upper control bar is released the blade should
stop within 3 seconds.
Additional maintenance instructions are found on Page 14.
WARNING
NEVER insert a hand or any other object in the grass
discharge chute to verify that the blade has stopped.
If the blade continues to rotate (no change in the
noise or size of the grass bag) after releasing the
upper control bar it is an indication of a malfunction
of the BBC system.
If the blade did not stop during the BBC Function Test
procedure or if you are unsure - Immediately stop the
engine by using the throttle control on the left side of
the control panel. The BBC system will require a repair
before further use. Immediately contact an authorized
Bad Boy dealer for advice. Do not under any
circumstances defeat the function of the BBC system.
This can cause serious injury or death.

BBC Function Test - Before each use
A simple test to verify the BBC function is to install an empty
grass collection bag. The mulch plug should not be installed.
1. Start the engine.
2. Engage the blade per above procedure. Notice how the
noise changes and that the bag becomes “infl ated”.
3. Release the upper control bar. If the bag does not “defl ate”
immediately, it indicates that the blade is still engaged and
rotating.
4. IF the bag defl ated - verify that the blade has stopped rotat-
ing by removing the grass bag and look at the stopped blade
through the grass discharge chute.

2
When operating the lower control
bar (1) typical movement on the
red adjustment knob (3) should be
between 1/4” to 3/8” (6 to 10 mm)
DRIVE CONTROL
The drive system consists of a two speed transmission and an
adjustable belt drive from the engine to the transmission.
The transmission speed can be set to LO - N - HI.
HI speed is approximately 4mph - a fast walking speed.
LO speed is approximately 3mph - an average walking speed.
The shifter arm is intentionally made fl exible. When the arm is
locked in the LO or the HI position the transmission will
automatically mesh into the gears as soon as the drive is
engaged by operating the lower control bar.
ENGAGING THE DRIVE
To engage and disengage the drive system pull up on the
lower control bar (1). Typically the drive will engage when the
lower control bar is approximately 1 to 1.5 inches from the
handle (2).
Notice
Due to wear, the drive engagement position of the lower
control bar can change. If the distance between the lower
bar and the handle (2) is less than a 1/4 inch when the mower
starts to drive make an adjustment on the red knob located
below the engine fuel tank (3).
If needed turn the red knob 2 turns clockwise. Verify the drive
position of the control bar by operating the mower. If needed
repeat the adjustment.
HEIGHT ADJUSTMENT
Each wheel can be adjusted individually to a specifi c cutting
height from 1 inch to 4.5 inch. Notice: It is only possible to
move the adjustment on one side 2 steps each time.
Moving the front wheel height adjusters forward raises the
cutting height. Moving the rear wheel height adjusters towards
the rear of the mower raises the rear cutting height.
Always adjust the height adjusters to the same position both in
the front and the rear for best cutting results.
WARNING
Never readjust the cutting height while the engine
is running. STOP the engine. Never lift the
mower by placing your hand or fi ngers under the
edge of the mower deck.
MODES OF OPERATION
This mower is approved to be used in two diff erent operational
modes:
1 With a grass catcher in place
The grass catcher supplied with this mower has been tested
for compatibility. It is important to always inspect the catcher
for deterioration. If the material is ripped or worn the bag shall
not be used.
2. With the mulch plug installed
If the mulch plug is installed ensure that the rear door can
close completely.
WARNING
Do not operate the lawn mower without the mulch
plug or the grass catcher in place. Never attempt
to operate the mower with the rear door removed,
damaged or propped open.

Adjust the valve clearance.
NOTICE
Several of the operations described in this
Maintenance section involves placing the mower
on its right side.
To avoid spills of oil and gasoline always:
- Place the mower on a hard surface such as a
concrete driveway or a garage fl oor.
- Never place the mower on its side when there is
gasoline in the tank - do the service of the mower
when you have run out of gasoline during normal
operation.
- Always make sure that the Oil Filler Cap is
tightened.
Any spillage of oil or gasoline can be extremely
fl ammable and explosive and under certain
conditions can cause serious personal injury and
property damage.
CLEANING THE MOWER
We do not recommend using a garden hose to clean the
mower. The buildup of moist grass, fertilizer and water can
cause extreme corrosion damage to many parts of the mower
and the engine.
Never use a Pressure Washer:
The use of a pressure washer can force water and moisture
into ball bearings and engine parts and cause substantial dam-
age.
- Clean the underside of the mower by scraping any build-up
of grass and trash.
- Clean off the outside of the engine and the top of the mower
with compressed air. Any accumulation of debris under the
belt cover can typically also be removed with compressed air
without removing the protective belt cover.
- Wash the Grass Bag with a garden hose frequently. The
holes that allows the grass bag to breathe will eventually clog
with dirt. A clogged bag will not collect the grass clippings
eff ectively. Do not install and use a wet grass catcher. It will
plug prematurely.
13
BLADE MAINTENANCE
For best results, the mower blade must be kept sharp. Always
replace a bent or damaged blade.
Removing the blade
1. Disconnect spark plug wire from spark plug and place wire
where it cannot come in contact with plug.
2. Turn lawn mower on its right side. (Make sure air fi lter and
carburetor are up).
3. Use a wood block between blade and mower deck to
prevent blade from turning when removing blade bolts.
NOTE: Protect your hands with gloves and/or wrap the blade
with a heavy cloth.
4. Remove blade bolts by turning counter-clockwise with a
11/16” (17mm) wrench or socket.
Installing the blade
1. Position the blade with the bent corner of the blade (sail)
pointing towards the deck. Install the blade bolts. Important:
Blade bolts are heat treated. If the bolts are worn or damaged
use only bolts available from Bad Boy.
2. Use a block of wood between blade and mower deck and
tighten the blade bolts. Always use a torque wrench.
The recommended tightening torque is 30 to 35 ft. lbs.
(40 to 45 Nm)
WARNING
Use only a replacement blade approved by Bad Boy.
com. Using a blade not approved by Bad Boy is
hazardous. It can damage your mower and cause
serious personal injury.
A worn or damaged blade can break and parts of the
blade could be thrown into the operators or bystanders
area, resulting in serious personal injury or death.
Inspecting the blade
Carefully examine the blade for straightness, damage and
abnormal wear. In some areas abrasive sand and dust can
wear away the metal of the blade - see illustration.

MAINTENANCE
Sharpening the blade
File the top side of the blade (1) and maintain the original
angle of the cutting edge. Maintain the radius where the cut-
ting edge ends. Always remove the same amount of material
from both ends of the blade. This ensures that the blade stays
balanced.
If sharpening is done with a grinding stone the blade should
always be balanced using a blade balancing device. A blade
balance tool is available from Bad Boy or most lawn and
garden dealers, and hardware stores.
If the blade shows wear or cracking at the edge where the
blade is bent up (3) it must immediately be replaced.
ENGINE OIL CHANGE
NOTICE: Before tipping lawn mower on its right side to drain
oil, empty fuel tank by running engine until fuel tank is empty.
1. Disconnect spark plug wire from spark plug and place wire
where it cannot come in contact with plug.
2. Remove oil fi ller cap/dipstick.
3. Tip lawn mower on its right side as shown and drain oil
into a suitable container. Rock lawn mower back and forth to
remove any oil trapped inside of engine.
4. Wipe off any spilled oil from lawn mower or side of engine.
5. Fill engine with oil. Slowly pour oil down the oil fi ll spout into
the engine. Use an SAE 10W-30 oil 24 Fl.Oz - 0.7 Liter
See engine Owner’s Manual for complete information.
6. Wait one minute to allow oil to settle. Use the gauge on oil
fi ller cap/dipstick for checking level. Insert the dipstick into the
tube and tighten it for a proper reading before adding more oil.
7. Continue adding small amounts of oil and rechecking
the dipstick until it reads full. DO NOT overfi ll, or engine
will smoke on startup.
8. Always be sure to retighten oil fi ll cap/dipstick before
starting engine.
9. Reconnect spark plug wire to spark plug.
