•  Never fi ll containers inside a vehicle, on 

a truck or trailer bed with a plastic liner.  
Always place containers on the ground 
away from your vehicle before fi lling.

•   Remove gas-powered equipment from 

the truck or trailer and refuel it on the 
ground.  If this is not possible, then 
refuel such equipment with a portable 
container, rather than from a gasoline 
dispenser nozzle.

•   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.

•   If fuel is spilled on clothing, change 

clothing immediately.

•  Never overfi ll fuel tank.  Replace gas 

cap and tighten securely.

•   Never run a machine inside a closed 

area.

•   Never make adjustments or repairs with 

the engine (motor) running. Dis con nect 
the spark plug wire, and keep the wire 
away from the plug to prevent ac ci den tal 
starting.

 • Keep nuts and bolts, especially blade 

attachment bolts, tight and keep equip-
ment in good condition.

•   Never tamper with safety devices. Check 

their proper operation reg u lar ly.

 • Keep machine free of grass, leaves, or 

other debris build-up. Clean oil or fuel 
spillage. Allow machine to cool before 
storing.

•   Stop and inspect the equipment if you 

strike an object. Repair, if nec es sary, 
before restarting.

•   Never attempt to make wheel height 

adjustments while the engine is running.

•   Grass catcher components are sub ject 

to wear, dam age, and de te ri o ra tion, 
which could expose moving parts or 
allow objects to be thrown. Frequently 
check com po nents and replace with 
man u fac tur er’s recommended parts, 
when necessary.

•   Mower blades are sharp and can cut. 

Wrap the blade(s) or wear gloves, and 
use extra caution when ser vic ing them.

•   Do not change the engine governor set-

ting or overspeed the engine.

•   Maintain or replace safety and instruc-

tion labels, as necessary.

 WARNING: This lawn mower is equipped with an internal com bus tion engine and 

should not be used on or near any un im proved forest-covered, brush-covered or 
grass-cov ered land unless the engine’s exhaust system is equipped with a spark 
arrester meeting applicable local or state laws (if any).  If a spark arrester is used, it 
should be maintained in effective working order by the operator.
In the state of California the above is required by law (Section 4442 of the California 
Public Resources Code).  Other states may have similar laws.  Federal laws apply on 
federal lands.  A spark arrester for the muffl er is available through your nearest Sears 
Parts & Repair Center (See the REPAIR PARTS section of this manual).
