HOW TO USE YOUR LAWN 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 adjustments or repairs. We recom- mend 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.

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

your lawn mower and void your warranty.

ENGINE ZONE CONTROL

ENGINE SPEEDCAUTION: Federal regulations require an engine control to be installed on this lawn mower in order to minimize the risk of blade contact injury. Do not under any circumstances attempt to defeat the function of the operator control. The blade turns when the engine is running.

Your lawn mower is equipped with an operator presence 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 stopping engine, release the drive control lever only. Hold operator presence control bar down against handle to continue mowing without self-propelling.

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

DRIVE CONTROL ADJUSTMENT

Over time, the drive control system may be- come “loose”, resulting in decreased speed. There is a turnbuckle on the underside of the drive control housing to increase tension on the drive cable. Proceed 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.

Raise wheels for low cut and lower wheels for high cut, adjust cutting height to suit your requirements. Medium position is best for most lawns.

To change cutting height, squeeze ad- juster lever toward wheel. Move wheel up or down to suit your requirements. Be sure all wheels are in the same setting.

NOTE: Adjuster is properly positioned when plate tab inserts into hole in lever. Also, 9- position adjusters (if so equipped) allow lever to be positioned between the plate tabs.

2.The grass catcher is secured to the lawn mower housing when the rear door is

lowered onto the grass catcher frame. TO ADJUST CUTTING HEIGHTCAUTION: Do not run your lawn mower without mulcher plug or approved grass catcher in place. Never attempt to op- erate the lawn mower with the rear door removed or propped open.
