The starter should crank only when the operator is in the seat, the parking brake is applied, blade switch off and the motion control levers in the neutral slots. If the machine starts with any of these controls in an operating position, turn the machine off and repair the system immediately. Cutter Housings Grease housings once weekly or every 40 to 50 hours of use. Use a good synthetic grease. Pump grease in until a small amount purges from the popet on the underside of the deck. Check the torque of the pulley bolt (45 ft/lbs) should be maintained. 21 “F” Full Mark MAINTENANCE Hardware Check daily. Inspect the entire machine for loose or missing hardware. Air filter See engine manufacturers specifications for cleaning and replacement intervals. ONLY USE Tri-Synthetic Formula Hydraulic system Check oil level in tank daily. Oil level should be 3/ 4” to 1” below the top of the tank. Check all fittings, hoses and lines for damage or leaks. Replace 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. 0 FIG - 11 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 operation. 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 control 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 occurred 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 damage can occur to the pumps and wheel motors. To replace belt lower the deck to its lowest position. 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 proceedure for installation. See the decal on the top of deck for belt routing information. FIG - 12. After installation is complete check the belt for twists. WARNING! If a leak is suspected, use a piece of cardboard 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. FIG - 12 22 MAINTENANCE FIG - 13 Caster Wheels Pump belt Check every 200 hours.
