•   Read, understand, and follow all 

in struc tions on the machine and in the 
manual(s) before starting. Be thor ough ly 
familiar with the controls and the proper 
use of the machine before starting.

•   Do not put hands or feet near or under

operate the machine.

•   Clear the area of objects such as rocks,

be picked up and thrown by blade.

•   Be sure the area is clear of other people 

before mowing. Stop the ma chine if 
anyone enters the area.

•   Do not operate the mower when bare-

 foot or wearing open sandals. Al ways 
wear substantial foot wear.

•   Do not pull mower backwards unless abso-

lutely nec es sary. Always look down and be-
hind before and while moving backwards.

•   Never direct discharged material toward 

anyone. Avoid discharging material 
against a wall or obstruction.  Material may 
richochet back toward the operator.  Stop 
the blade when crossing gravel surfaces.

•   Do not operate the mower without  prop-

•   Stop the engine (motor) whenever you 

leave the equip ment, before clean ing

•   Never operate machine in wet grass. 

Always be sure of your footing: keep a 
fi rm hold on the handle; walk, never run.

•   Disengage the self-propelled mech-

 a nism or drive clutch on mowers so 
equipped before starting the engine.

•   If the equipment should start to vi brate 

abnormally, stop the engine (motor) and 
check immediately for the cause. Vibra-
tion is generally a warning of trouble.

•   Always wear safety goggles or safe ty glass-

es with side shields when op er at ing mower.

Slopes are a major factor related to slip & 
fall accidents which can result in severe 
injury. All slopes require extra caution. If 
you feel uneasy on a slope, do not mow it.
