CONTROLS

Throttle Control

The throttle control regulates the engine speed and thereby the rate of rotation of the blades, assuming the blade engagement control is engaged (pulled up).

In order to increase or decrease the engine speed, the control is moved forward or backward respectively.

Avoid idling the engine for long periods, as there is a risk of the spark plugs fouling.

For best mower performance, USE FULL THROTTLE WHEN MOWING.

Neutral Lock

Located on top the motion controls, the neutral locks keep the unit from moving while idling. The locks should be activated when starting the engine. To disengage the locks, squeeze slightly upward on the driver levers and using thumbs, slide the neutral locks back.

IMPORTANT INFORMATION

Be sure neutral locks are either fully forward (locked) or fully back (unlocked). If the neutral lock is between full forward and full back, the machine will not track properly.

Tracking Adjustment

If the mower is not tracking straight, check the air pressure in both rear tires. Recommended air pressure is 15 psi (1 bar). Tracking should be checked on a flat, level surface.

Loosen the lock knob (1). Turn the tracking knob (2) clockwise to adjust the mower to the left. Turn the knob counter-clockwise to adjust the mower to the right.
