MAINTENANCE
Hardware
Check daily. Inspect the entire machine for loose or missing hardware.
Air filter
See engine manufacturers specifications for cleaning and replacement intervals.
Hydraulic system
Check oil level in tank daily. Oil level should be 3/ 4” to 1” below the top of the tank. Check all fit- tings, hoses and lines for damage or leaks. Re- place or repair any questionable lines or fittings.
Change the oil and filter after the first 250 hours of operation then annually after that. Drain tank and remove filter, be sure to clean around the tank and filter head before removal. Replace filter and drain plug and refill hydraulic tank. Only use MOBIL 1 synthetic oil. FIG - 11
Raise and block up the rear of the machine so the drive wheels can rotate freely. Start the engine at the lowest RPM possible, move the motion con- trol levers forward and run machine for several minutes. Stop engine and recheck the oil level.
If the wheels do not respond an air lock has oc- curred within the system. The system must be bled off of air or let the machine set overnight to allow the air time to dissipate out of the oil. DO NOT run the machine with an air lock serious dam- age can occur to the pumps and wheel motors.
WARNING!
If a leak is suspected, use a piece of card- board or wood, NOT your hands. to check for leaks.
Escaping hydraulic oil under pressure can have sufficient force to penetrate the skin, causing serious injury.
If injured by escaping fluid, see a doctor at once. Serious infection or reaction can develop if proper medical treatment is not administered immdediately.

Deck belt
Check every 75 to 100 hours of operation. Check for severe cracking and large nicks. NOTE: The belt will show some small cracks in normal op- eration.
To replace belt lower the deck to its lowest posi- tion. Remove the foot plate and belt shields. Use a ratchet with a 9/16” socket on the spring idler bolt to relieve the tension on the belt. Slide the belt off of pulley and fully remove the belt. Reverse the procedure for installation. See the decal on the top of deck for belt routing information. FIG - 12.
