Husqvarna HU775L Operation Manual - Page 7

OPERATION OPERATION ENGINE SPEED The engine speed was set at the factory for optimum performance. Speed is not adjustable. 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. IMPORTANT: This lawn mower is shipped WITHOUT OIL OR GASOLINE in the engine. 2. Forward motion will stop when either the operator presence control bar or a drive control lever are released. To stop forward motion without stopping engine, release a drive control lever only. Hold operator presence control bar down against handle to continue mowing without self-propelling (Figure 7). NOTE: If after releasing the drive control the mower will not roll backwards, push the mower forward slightly to disengage drive wheels. 1 2 WARNING: The blade turns when the engine is running. ENGINE ZONE CONTROL 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. NOTE: 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 1. Self-propelling is controlled by holding the operator presence control bar down to the handle and pulling either drive control lever rearward to the handle. The further toward the handle a lever is pulled, the faster the unit will travel (Figure 6). DRIVE CONTROL DISENGAGED Figure 7 1. Operator presence control bar 2. Drive control levers 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. Proceed as follows: 1. Turn unit off; disconnect spark plug wire from plug. 2. Rotate turnbuckle on drive control to increase drive speed (Figure 8). 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 replaced. 1 2 1 TO ENGAGE DRIVE CONTROL Figure 6 1.
