DO:
•   Mow across the face of slopes: nev er 

up and down. Exercise extreme caution 
when changing direction on slopes.

•   Remove obstacles such as rocks, tree 

limbs, etc.

•   Watch for holes, ruts, or bumps. Tall 

grass can hide obstacles.

DO NOT:
•   Do not trim near drop-offs, ditches or 

embankments. The operator could lose 
footing or balance.

•   Do not trim excessively steep slopes.
•   Do not mow on wet grass. Reduced 

footing could cause slipping.

Tragic accidents can occur if the op er a tor is 
not alert to the presence of children. Children 
are often attracted to the ma chine and the 
mowing activity. 

Never assume that children 

will remain where you last saw them.
•  Keep children out of the trimming area 

and under the watchful care of an oth er 
re spon si ble adult.

•   Be alert and turn machine off if chil dren 

enter the area.

•   Before and while walking back wards, 

look behind and 

down for small chil dren. 

•   Never allow children to operate machine.
•   Use extra care when approaching blind 

corners, shrubs, trees, or other objects 
that may obscure vision.

Use extreme care in handling gasoline.  
Gasoline is extremely fl ammable and the 
vapors are explosive.
•   Extinguish all cigarettes, cigars, pipes 

and other sources of ignition.

•   Use only an approved container.
•   Never remove gas cap or add fuel with 

the engine running.  Allow engine to 
cool before refueling.

•   Never refuel the machine indoors.
•   Never store the machine or fuel contain-

er where there is an open fl ame, spark 
or pilot light such as a water heater or 
on other appliances.

•  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 equip-
ment 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 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 spill-
age. 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 Husqvarna or 
other authorized service center (See the REPAIR PARTS section of this manual).
