work area

your unit

all safety decals.

Clear work area of stones, sticks, wire and 
foreign objects which might be picked up and 
thrown. Tall grass can hide obstacles.

rocks, rough terrain and hidden hazards.

embankments that could cause operator to 
lose footing or control of unit.

along streets or curbs.

Keep work area clear of all persons, children 
and pets.

hold on handlebar. Walk, NEVER run.

or serious injury. DO NOT run engine in an 
enclosed area.

operating unit.

NEVER direct discharge toward bystanders. 

Operator is responsible for bystander safety.
DO NOT touch hot parts. Allow parts to cool.

Keep safety devices or guards in place and 
functioning properly. NEVER modify or 
remove safety devices.

in the manual and on the machine before 
starting. Understand:

How to operate all controls

work.

Keep feet away when starting engine.
DO NOT start the engine or operate mower 
without side discharge cover or side 
discharge deflector installed.

Never leave a running unit unattended.

Take all possible precautions when leaving 
unit unattended.
ALWAYS shut off engine, remove key 
(electric start models) and disconnect spark 
plug wire to prevent accidental starting or 
unauthorized use.

Stop engine if anyone enters the work area.

NEVER attempt to make any adjustments to 
unit while engine is running (except where 
specifically recommended). Stop engine, 
remove key (electric start models) and wait 
for all moving parts to stop before servicing. 
DO NOT make cutting height wheel 
adjustments while the engine is running.

If you strike an object, or if equipment 
vibrates abnormally, stop engine at once, wait 
for moving parts to stop and disconnect wire 
from spark plug. Repair any damage before 
restarting unit.

running unless the grass bag is in place. 
Stop engine before removing and emptying 
grass bag.

discharge cover.

discharge deflector.
