MEETS CPSC SAFETY REQUIREMENTS

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. The blade turns when the engine is running.

Operator presence control lever – must be held down to the handle to start the engine. Release to stop the engine. Drive control bar – used to engage power-pro pelled forward mo tion of mower. Mulcher door – allows con ver sion to discharging or bagging operation.

Primer– pumps additional fuel from the carburetor to the cylinder for use when starting a cold engine.

Starter handle – used for starting engine. Mulcher plug – located at the rear dis-

charge opening. Must be removed when converting to bagging operation.

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 standard safety glasses or a 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 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
