If your unit is equipped with a primer, prime 
engine as instructed in the separate engine 
manual packed with your unit.

•

Standing behind the unit, depress the blade 
control handle and hold it against the upper 
handle as shown in Figure 10.

•

Grasp the recoil starter handle as shown and 
pull slowly until resistance is felt, then pull 
rapidly to start engine and avoid kickback. 
Return it slowly to the rope guide bolt.

NOTE:  The blade control handle must be

the blade control handle to stop the engine and
blade.

1.

Release blade control handle to stop the engine and the blade.

2.

Disconnect spark plug wire from spark plug and ground against the engine.

Be sure the lawn is clear of stones, sticks, wire, or other objects which could damage the lawn mower 

or the engine. Such objects could be accidently thrown by the mower in any direction and cause serious personal 
injury to the operator and others.

The operation of any lawn mower can result in foreign objects being thrown into the eyes, 

which can damage your eyes severely. Always wear safety glasses while operating the mower, or while 
performing any adjustments or repairs on it.

Be sure no one other than the operator is standing near the lawn mower while starting 

engine or operating mower. Never run engine indoors or in enclosed, poorly ventilated areas. Engine 
exhaust contains carbon monoxide, an odorless and deadly gas. Keep hands, feet, hair and loose clothing 
away from any moving parts on engine and lawn mower. 

THIS CONTROL MECHANISM IS A SAFETY DEVICE. NEVER ATTEMPT TO BYPASS 

ITS OPERATION.

If you strike a foreign object, stop the engine. Remove wire from the spark plug, thoroughly 

inspect the mower for any damage, and repair the damage before restarting and operating the mower. 
Extensive vibration of the mower during operation is an indication of damage. The unit should be promptly 
inspected and repaired.
