Choke Control
Model MZ5225ZT only
The choke control is used for cold starts in order to provide the engine with a richer fuel mixture.
For cold starts the control should be pulled out to its extent.
Tracking Knob
If the mower is not tracking straight, check the air pressure in both rear tires. Recommended air pressure is 10 psi. (.7 bar) for the front tires and 15 psi (1 bar) for the rear tires. Tracking must be checked on a flat and level concrete or blacktop surface.
Rotating the tracking knob allows fine tuning adjustments so the machine tracks straight with the steering control levers in the full forward position.
Rotate the knob clockwise (as viewed from the operation position) to increase the speed on the left lever. Rotate counterclockwise to decrease speed.
