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.

III. CHILDREN

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

Never

mowing activity.

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,

down

look behind and

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.

IV. SAFE HANDLING OF GASOLINE

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 container 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 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.

V. GENERAL SERVICE

• 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 equipment 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 setting or overspeed the engine.

• Maintain or replace safety and instruction 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).

discharging or bagging operation. Drive control lever – used to engage power-pro pelled forward mo tion of mower.

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

result in severe eye damage. Always wear safety glasses or eye shields while operating your lawn mower or performing any ad just ments or repairs. We recommend a standard safety glasses or wide vision safety mask worn over spectacles.

DRIVE CONTROL ADJUSTMENT

Over time, the drive control system may become “loose”, resulting in decreased speed. There is a turnbuckle on the un der side of the drive control housing to increase tension on the drive cable. Pro ceed as follows:

1. Turn unit off and disconnect spark plug wire from spark plug.

2. Turn nut on underside of drive control to increase drive speed.

3. Operate mower to test drive speed. Readjust as required.

4. If condition fails to improve after the above steps (forward speed remains the same), your drive belt is worn and should be re placed.

DRIVE CONTROL

• Self-propelling is controlled by hold ing the operator presence control bar down to the handle and pulling the drive control lever rearward to the handle. The farther toward the handle the lever is pulled, the faster the unit will travel.
