I. GENERAL OPERATION

• Read, understand, and follow all

in struc tions on the machine and in the

familiar with the controls and the proper

use of the machine before starting.

• Do not put hands or feet near or under

rotating parts. Keep clear of the dis-

charge opening at all times.

• Only allow responsible individuals, who

are familiar with the in struc tions, to

operate the machine.

• Clear the area of objects such as rocks,

toys, wire, bones, sticks, etc., which could

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 absolutely nec es sary. Always look down and behind 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 proper guards, plates, grass catcher or oth er safety protective devices in place.

• See manufacturer’s instructions for proper operation and installation of accessories. Only use accessories approved by the manufacturer.

• Stop the blade(s) when crossing grav el drives, walks, or roads.

• Stop the engine (motor) whenever you leave the equip ment, before clean ing the mower or unclogging the chute.

• Shut the engine (motor) off and wait until the blade comes to complete stop before removing grass catcher.

• 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. Vibration is generally a warning of trouble.

• Always wear safety goggles or safe ty glasses with side shields when op er at ing mower.

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.

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).

Sears rotary walk-behind power lawn mowers conform to the safety standards of the American National Standards Institute and the U.S. Consumer Product Safety Com mis sion.

Operator presence control bar – must be held down to the handle to start the engine. Release to stop the engine.

Starter handle – used for starting engine.

WARNING: The blade turns when the engine is running.

Mulcher door – allows con ver sion to

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.

HOW TO USE YOUR LAWN MOWER

ENGINE SPEED

Engine speed was set at the factory for optimum performance. It is not adjustable.

ENGINE ZONE CONTROL

CAUTION: Federal regulations re quire

an engine control to be installed on this lawn mower in order to minimize the risk of blade contact injury. Do not un der any circumstances attempt to de feat the func tion of the operator con trol. The blade turns when the engine is running.

• Your lawn mower is equipped with an

operator pres ence control bar which requires the operator to be positioned behind the lawn mower handle to start and operate the lawn mower.

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.

• Forward motion will stop when either

the operator presence control bar or drive control lever are released. To stop forward motion without stop ping engine, re lease the drive control lever only. Hold op er a tor presence control bar down against handle to con tin ue mowing without self-propelling.

NOTE: If after releasing the drive control the mower will not roll backwards, push the mower forward slightly to disengage drive wheels.

DRIVE CONTROL ADJUSTMENT

Over time, the drive control system may become “loose”, resulting in decreased speed. There is a turnbuckle on 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. Rotate turnbuckle on 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.

Adjustment turnbuckle

TO ADJUST CUTTING HEIGHT

All four wheels are adjusted by a single lever.

• Pull adjuster lever toward wheel. To

raise mower, move lever forward to desired position. To lower mow er, move the lever toward the rear.
