HYDRAULIC SAFETY
1. Hydraulic fluid is under high pressure. If you need service on your hydraulic system, please see your dealer.
WARNING:
Keep your body and hands away from pin holes or nozzles that eject fluid under high pressure. Use paper or cardboard, not hands, to search for leaks.
Hydraulic fluid escaping under high pressure may have sufficient force to penetrate your skin and cause serious injury. If fluid is injected into your skin, a physician familiar with this form of injury must re­move it surgically within a few hours or gangrene may result.

Pull the idler arm down until the belt becomes slack and can be removed easily from the idler pulley . Slowly move the idler arm up until the stop bolt rests against the hydraulic tank support. Remove the old belt and mount the new belt around the engine drive pulley and the two pump pulleys. Feed the belt up toward the idler pulley.
Pull the idler arm down so that the new belt can easily be mounted on the idler pulley . Slowly move the idler arm up until the belt is firmly engaged. Remove the breaker bar and remount the belt guard. Check to ensure that the belt is riding properly in all pulleys.
ontrol Handle Position
Hand Control Handle Position
The position of the hand control handles can be adjusted for operator comfort. Loosen the bolts holding the handle to the lever bar just enough to allow movement of the handle. Adjust to position most comfortable for operator. Retighten the bolts.
4. Check the oil level (SAE 20W50) in the hydraulic reservoir . The reservoir is under the seat. The oil level should be 2" below the top of the tank. When performing oil changes, fill the reservoir until it is 2" below top of tank. (Approximately 4 quarts will be needed) DO NOT OVERFILL.
5. Check that all fasteners are tightened properly . Make sure all safety devices are in place and working correctly .
WARNING:
Gasoline is highly flammable. Be careful when filling the tank. Do not fill the tank while the engine is running or hot from operation. Ex­tinguish open flames, matches, and smoking materials before filling the tank. Do not over­fill the tank. Wipe up all gasoline spills.
6. Fill the fuel tank with clean, fresh, lead-free gasoline with a minimum octane rating of 87.
7. Check the safety interlock system. With the operator on the seat, the engine must not start unless the control handles are in the neutral lock position and the cutter drive is disengaged.
