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 adjustments or repairs. We recommend standard safety glasses or a wide vision safety mask over spectacles. HOW TO USE YOUR LAWN MOWER ENGINE SPEED The engine speed was set at the factory for optimum performance. Speed is not adjustable. ENGINE ZONE CONTROL OPERATOR PRESENCE CONTROL BAR DRIVE CONTROL BAR CAUTION: 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 mower handle to start and operate the mower. DRIVE CONTROL (See Fig. 5) • Self-propelling is controlled by holding the operator presence control bar down to the handle and pulling the drive control bar up to the handle. The closer to the handle the bar is pulled, the faster the unit will travel. • Forward motion will stop when either the operator presence control bar or drive control bar are released. To stop forward motion without stopping engine, release the drive control bar 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 mower forward slightly to disengage drive wheels. DRIVE CONTROL ADJUSTMENT (See Fig. 6) Over time, the drive control system may become "loose", resulting in decreased speed. There is an adjustment turnbuckle on the drive control cable to increase tension on the drive belt. Proceed as follows: 1. Turn unit off and disconnect spark plug wire from spark plug. NOTE: Your mower is shipped with no "gap" between drive control cable and jam nut. 2. To increase drive speed, rotate turnbuckle on drive control cable until there is a small "gap" between drive control cable and jam nut. 3. Operate mower to test drive speed. Readjust as required. IMPORTANT: OVER-ADJUSTMENT WILL MAKE IT DIFFICULT TO LIFT CONTROL BAR TO HANDLE AND WILL CAUSE YOUR MOWER TO "CREEP" FORWARD WHEN CONTROL BAR IS RELEASED. 4. Tighten jam nut against turnbuckle. If condition fails to improve after the above steps (forward speed remains the same), your drive belt is worn and should be replaced. DRIVE CONTROL ENGAGED DRIVE CONTROL DISENGAGED FIG. 5 ORIGINAL FACTORY SETTING (NO "GAP") JAM NUT DRIVE CONTROL CABLE TURNBUCKLE "GAP" WHILE ADJUSTING "GAP" AFTER ADJUSTMENT FIG. 6 TO ADJUST CUTTING HEIGHT (See Fig. 7) 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 adjuster 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.
