CAUTION!
Risk of burns to exposed skin.
Hydraulic oil becomes hot during
operation. Hoses, lines, and other
parts become hot as well. Wait for
the oil and components to cool
before starting any maintenance or
inspection work.
Change the hydraulic fluid at 100 hours of operation or
annually.
• Hydraulic oil type: Dexron® III ATF
• Hydraulic reservoir volume: 4.8 US gal (18 L). An extra
1/2 gal (1–2 liters) may be required to top up the circuit.
There are two hydraulic tank drain plugs located under the
machine. Both must be removed to fully drain the tank. Place the
machine in a Safe Condition. See page 9.
A 3/8" hex key is required to remove the drain plugs.
NOTE: Earlier models had one drain plug.
Procedure
1. Place a drain pan of suitable capacity under the drain plugs.
2. Clean the area around drains and remove the drain plugs.
3. Allow the oil to fully drain, then flush the tank.
4. Dispose of used oil in an environmentally safe manner.
5. Replace the plug and fill the tank with clean oil, up to the
full mark on the dipstick.
6. Start the machine up and cycle hydraulic functions to purge
air from the system.
7. Stop the engine and recheck the oil level. Top up to the full
mark.
