Operation
Adding Fuel
Use Unleaded Regular Gasoline suitable for
automotive use (85 octane minimum).
Important: Never use methanol, gasoline
containing methanol, or gasohol containing more
than 10% ethanol because the fuel system could be
damaged. Do Not mix oil with gasoline.
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or explosion
from gasoline can burn you and others and can
damage property.
• Fill the fuel tank outdoors, in an open area, when
the engine is cold. Wipe up any gasoline that spills.
• Never fill the fuel tank inside an enclosed trailer.
• Do Not fill the fuel tank completely full. Add
gasoline to the fuel tank until the level is 1/4 to 1/2
inch (6 to 13 mm) below the bottom of the filler neck.
This empty space in the tank allows gasoline to
expand.
• Never smoke when handling gasoline, and stay
away from an open flame or where gasoline fumes
may be ignited by a spark.
• Store gasoline in an approved container and keep
it out of the reach of children. Never buy more than
a 30-day supply of gasoline.
• Do Not operate without entire exhaust system in
place and in proper working condition.
In certain conditions during fueling, static electricity
can be released causing a spark which can ignite
the gasoline vapors. A fire or explosion from
gasoline can burn you and others and can damage
property.
• Always place gasoline containers on the ground
away from your vehicle before filling.
• Do Not fill gasoline containers inside a vehicle or
on a truck or trailer bed because interior carpets or
plastic truck bed liners may insulate the container
and slow the loss of any static charge.
• When practical, remove gas-powered equipment
from the truck or trailer and refuel the equipment
with its wheels on the ground.
• If this is not possible, then refuel such equipment
on a truck or trailer from a portable container, rather
than from a gasoline dispenser nozzle.
• If a gasoline dispenser nozzle must be used, keep
the nozzle in contact with the rim of the fuel tank or
container opening at all times until fueling is
complete.
Gasoline is harmful or fatal if swallowed. Long-term
exposure to vapors can cause serious injury and
illness.
• Avoid prolonged breathing of vapors.
• Keep face away from nozzle and gas tank or
container opening.
• Keep gas away from eyes and skin.
Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the machine to
provide the following benefits:
• Keeps gasoline fresh during storage of 90 days or
less. For longer storage, it is recommended that the
fuel tank be drained.
• Cleans the engine while it runs
• Eliminates gum-like varnish buildup in the fuel
system, which causes hard starting
Important: Do Not use fuel additives containing
methanol or ethanol.
Add the correct amount of gas stabilizer/conditioner
to the gas.
Note: A fuel stabilizer/conditioner is most effective
when mixed with fresh gasoline. To minimize the
chance of varnish deposits in the fuel system, use
fuel stabilizer at all times.
Filling the Fuel Tank
Shut the engine off.
Clean around fuel tank cap and remove the cap.
Add unleaded regular gasoline to fuel tank, until the
level is 1/4 to 1/2 inch (6 to 13 mm) below the
bottom of the filler neck. This space in the tank
allows gasoline to expand. Do Not fill the fuel tank
completely full.
Install fuel tank cap securely. Wipe up any gasoline
that may have spilled.
Checking the Engine Oil Level
Before you start the engine and use the machine,
check the oil level in the engine crankcase; refer to
Checking Oil Level in Engine Maintenance.

Think Safety First
Carefully read all the safety instructions and decals
in the safety section. Knowing this information could
help you or any bystanders avoid injury.
The use of protective equipment for eyes, hearing,
feet and head is recommended.
This machine produces sound levels in excess of 85
dBA at the operator’s ear and can cause hearing
loss through extended periods of exposure.
Wear hearing protection when operating this
machine.
Starting the Engine
1. Connect the wire(s) to the spark plug(s).
2. Open the fuel valve.
3. Lock both motion control levers in neutral.
4. Move the throttle control to run and pull the choke
knob to the on position before starting a cold engine.

Note: A warm or hot engine may not require
choking. To start a warm engine, move throttle
control midway between the run and slow positions.
Turn the ignition key to the start position to energize
the starter. When the engine starts, release the key.
Note: Do Not engage the starter for more than 5
seconds at a time. If the engine fails to start, allow
for a 15 second cool-down period between attempts.
Failure to follow these instructions can burn out the
starter motor.
When engine starts, move the throttle control
between the run and slow position. On electric start
models push the choke lever to the off position.
Allow the engine to warm up and then move the
throttle control to the run position.
Stopping the Engine
Move the motion control levers to the neutral
position.
Move the throttle lever to slow.
If the engine has been working hard or is hot, let the

To stop the engine, turn the ignition key to Off.
Important: Make sure fuel shut off valve is closed
before transporting or storing the machine, as fuel
leakage may occur. Before storing the machine, pull
the wire off spark plug(s) to prevent possibility of
accidental starting.
Moving Forward or Backward
The throttle control regulates the engine speed as
measured in rpm (revolutions per minute). Place the
throttle control in the Run position for best
performance. Always operate in the full throttle
position when mowing.
• Machine can spin very rapidly. Operator may lose
control of machine and cause personal injury or
damage to machine.
• Use caution when making turns.

Side Discharging or Mulching the Grass
This mower has a hinged grass deflector that
disperses clippings to the side and down toward the
turf.
Without the grass deflector, discharge cover, or
complete grass catcher assembly mounted in
place, you and others are exposed to blade
contact and thrown debris. Contact with rotating
mower blade(s) and thrown debris can cause
injury or death.
• Never remove the grass deflector from the mower
because the grass deflector routes material down
toward the turf. If the grass deflector is ever

The Safety Interlock System
If safety interlock switches are disconnected or
damaged, the machine could operate unexpectedly
causing personal injury.
• Do Not tamper with the interlock switches.
• Check the operation of the interlock switches daily
and replace any damaged switches before operating
the machine.
Understanding the Safety Interlock Systems
The safety interlock system is designed to prevent
the mower blades from rotating unless:
• The left motion control lever is pressed down.
• The blade engagement control lever (PTO) is
moved to the On position.
The safety interlock system is designed to stop the
engine if you release the left motion control lever
with the mower blades engaged.
The safety interlock system is designed not to allow
the engine to start unless the right motion control
lever is in the neutral position.
Testing the Safety Interlock System
Test the safety interlock system by testing the wheel
drive and blade drive systems before you use the
machine each time.
Wheel Drive System
Hold the right side motion control lever forward and
try to start engine. The engine should not start.
Blade Drive System
Start the engine.
Depress the left side motion control lever.
Continue holding the left side motion control lever in
the depressed position and move the blade
engagement control lever (PTO) to the ON position.
The clutch should engage and the mower blades
should begin rotating.
Release the left side motion control lever. The
engine should stop and blades should stop rotating.
Note: If the safety system does not operate as
described above, contact Better Outdoor Products™
immediately.

Maintenance
Servicing the Engine Oil
Check the engine oil level daily when in use.
Change the engine oil as follows:
• After the first 8 operating hours
• After every 50 operating hours
Note: Change the oil more frequently when the
operating conditions are extremely dusty or sandy.
Oil Type: Detergent oil (API service SF, SG, SH, or
SJ)
Note: Using multi grade oils (5W-20, 10W-30 and
10W-40) will increase oil consumption and IS NOT
recommended. Check oil level more frequently when
using them.
Kawasaki Crankcase Capacity: 58 ounces (1.7 liter)
with the filter removed; 51 ounces (1.5 liter) without
the filter removed. Refer to the table Figure 14.
Figure 14
Checking the Engine Oil Level
1. Park the machine on a level surface.
2. Disengage the PTO.
3. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
4. Clean around the oil dipstick (Figure 15) so that dirt
cannot fall into the filler hole and damage the
engine.
Figure 15
1. Oil dipstick
2. Filler tube
5. Unscrew the oil dipstick and wipe the end clean
Figure 15.
6. Slide the oil dipstick fully into the filler tube, but do
not thread onto tube.
7. Pull the dipstick out and look at the end. If the oil
level is low, slowly pour only enough oil into the filler
tube to raise the level to the Full mark.
Important: Do Not overfill the crankcase with oil
and run the engine; engine damage can result.
Changing the Oil (50hrs)
1. Start the engine and let it run five minutes. This
warms the oil so it drains better.
2. Park the machine so that the rear of the machine is
slightly lower to assure the oil drains completely.
3. Disengage the PTO.
4. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
5. Place a pan below the drain hose. Remove oil drain
plug to allow oil to drain Figure 16.
6. When oil has drained completely, reinstall the drain
plug.

falling into the engine and potentially causing
damage.
Using a spark plug wrench, remove the spark plug(s)
and the metal washers.
Checking the Spark Plug(s)
Look at the center of the spark plug(s) Figure 19. If
you see light brown or gray on the insulator, the
engine is operating properly. A black coating on the
insulator usually means that the air cleaner is dirty or
other rich condition.
If needed, clean the spark plug(s) with a wire brush
to remove carbon deposits.
