Filling oil
• Lift hinged pad and remove hex socket plug.
• Using a funnel, fill tank through oil level port until oil
reaches bottom threads of the port.
Rotate both of the hydro bypass valve levers on the side of each hydraulic pump about ½ turn
counterclockwise. It is important not to over tighten these levers. Damage may occur to the pump if this
valve is over tightened.
Whenever servicing the hydraulic system, it is of the utmost importance to keep any dirt or debris from
getting into the system. Clean off all parts before disassembly and assembly. When any of the hydraulic
parts are disconnected or removed or when the oil is changed, air must be bled from the system. If air is
entrained in the system, loss of power, excessive heat, and damage to the hydraulic pumps may occur.
First, make sure the oil level in the reservoir is correct. The oil should be level with the bottom threads of the
oil level port. Use fully synthetic oil: Mobil1 15W-50. With the bypass valves open and the engine running,
slowly move the control levers back and forth five or six times. Now close the bypass valves and with the
engine running, slowly move the control levers back and forth five or six times. It may be necessary to
repeat the above steps until all the air is purged and the rear wheels are turning at normal speed. After
purging is complete, adjust the oil level in the reservoir if necessary.
Grease with No. 2 general purpose lithium base or molybdenum base grease.
• Set parking brake, stop the engine and remove the key.
• Clean grease fittings with a rag.
• Connect grease gun to fitting and pump until grease begins to ooze out from the bearings.
• Wipe off excess grease.
• Do not use spray lube of any kind on choke and/or throttle cables.
