Husqvarna 5521CH How To Use Your Lawn Mower, Engine Speed, Engine Zone Control, To Convert Mower

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 per- formance. Speed is not adjustable.

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.

•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 (See Fig. 3)

•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 pres- ence 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.

•To keep drive control engaged when turning corners, push down on the handle to lift the front wheels off the ground while turning lawn mower.

DRIVE CONTROL ADJUSTMENT (See Fig. 3)

Over time, the drive control system may become “loose”, resulting in decreased speed. There is a thumbscrew on the underside of the drive control housing to increase ten- sion on the drive cable. Proceed as follows:

1.Turn unit off and disconnect spark plug wire from spark plug.

2.Rotate thumbscrew counter-clockwise to tighten the drive cable.

3.Operate mower to test drive speed.

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

NOTE: If mower begins to “creep” forward, the drive cable is too tight. Rotate thumbscrew clockwise to loosen drive cable.
