Husqvarna Z554 Owner Manual - Page 26

MAINTENANCE Safety System The machine is equipped with a safety system that prevents starting or driving under the following conditions. The engine can only be started when: • the mower deck is disengaged. • the steering / park brake controls are in the outer, locked neutral position, making sure of full parking brake engagement for a safe startup. NOTE: If the steering / park brake controls are not holding in the full outboard position, the tension can be adjusted. (See Park Brake in this section). Make daily inspections to make sure that the safety system works by trying to start the engine when one of the conditions is not met. Change the conditions and try again. Make sure the engine stops when the park brake is not engaged and the operator leaves the seated position. Make sure the engine stops if the mower blades are engaged and the driver leaves the seated position. IMPORTANT INFORMATION To drive, the driver must sit in the seat and the steering / park brake controls must be moved into the engaged (outer) position. Otherwise the engine will stop. Caster Wheels Anti-scalp Rollers Anti-scalp rollers keep the deck in the proper position to help prevent scalping in most terrain conditions. Do not adjust the rollers to support the deck. IMPORTANT INFORMATION Adjust antiscalp rollers with the mower on a flat level surface. To avoid deck damage, the anti-scalp rollers must not be adjusted to support the deck. Anti-scalp rollers can be set in three positions. • Upper 1-1/2" to 2-1/2" (38 mm - 64 mm) grass • Middle 2-1/2" to 4" (64 mm -102 mm) grass • Lower 4" to 5" (102 mm - 127 mm) grass The rollers must be approximately 1/4" from ground. Do not adjust the rollers to support the deck. Cleaning CAUTION! Always wear eye protection when cleaning and washing. Check every 200 hours. Check that wheels rotate freely. To replace, remove nut and caster bolt. Pull the wheel out of the fork. Install in reverse order. Tighten caster bolt. Torque to 50 ft-lbs (67.8 Nm). NOTE: Tire must rotate freely but axle spacers must not. If wheels do not rotate freely take the unit to the dealer for service. Regular cleaning and washing, especially under the mower deck, will increase the machine's lifespan. Make it a habit to clean the machine directly after use (after it is cooled), before the dirt sticks. Do not spray water on the top of the mower deck. Use compressed air to clean the top side of mower deck. Regularly clean deck and underside of the deck with normal water pressure. Do not use a high pressure washer or steam cleaner. Avoid spraying engine and electrical components with water. Do not rinse hot surfaces with cold water. Let unit cool before washing. Hardware Check daily. Inspect the entire machine for loose or missing hardware. 26
