MAINTENANCE

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 - 12

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.
