The cutting height range is from 1½" (38mm) to 4" (102mm) in ½ (13mm) increments. The heights are measured from the ground up to the blade tip with the engine not running. IMPORTANT INFORMATION In order to obtain an even cutting height, it is important that the air pressure in all tires is 15 psi / 103 kPa / 1 bar. 8058-019 The mower deck’s lifting lever IMPORTANT INFORMATION Always raise the deck to the highest position for transport. 22 CONTROLS Seat Adjustment Lever The seat can be adjusted lengthways.

The hour meter cannot be manually reset. 8052-001 Hour meter Tracking Knob If the mower is not tracking straight, check the air pressure in both rear tires. Recommended air pressure is 15 psi (103 kPa / 1 bar) for all 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. • Check that there is sufficient fuel in the fuel tank. • Adjust the seat to the desired position. The following conditions must be fulfilled before the engine can be started: • The blade switch for engaging the mower blades must be depressed. • Both steering controls must be in the locked (outer) neutral position. 8058-019 Starting the Engine • • Sit on the seat. Raise the mower deck by pushing the release button on the top of the lifting lever. Pull the lifting lever backward to the locked position (transport) position. Activate the parking brake by pushing the release button in and pulling the lever fully upwards. Set mower deck to transport position • 8058-020 Pull parking brake upwards to activate. Disengage the mower blades by pressing the blade switch downwards. 8052-001 Depress blade switch 25 OPERATION Move the steering controls outward to the locked (outer) neutral position. 8061-026 Place controls in neutral position Move the throttle to the middle position. 8052-001 Set the throttle If the engine is cold, the choke control should be pulled up. 8052-001 26 Set the choke control OPERATION Press in and turn the ignition key to the start position. 8050-780 Turn to the start position When the engine starts, immediately release the ignition key back to the run position.
