Hydraulic Oil Filters
- Change
Charge Filters
The (3) hydraulic oil charge filters are located directly on the
drives (Accessible by tilting the cab up). Using the a strap
wrench, remove and replace the filter(s).
Return Filter
The hydraulic return filter (4) is accessible from the right
hand side of the engine compartment, behind the Hydraulic
filler tube. Using a strap wrench, remove the oil filter and
replace with a new filter.
Hydraulic Oil - Change
1. Steam clean the pumps, motors, cylinders, hydraulic
lines, fittings and tank.
2. Place the machine on level ground.
3. Place containers on the ground under the hydraulic
tank drain plugs.
4. Open the hydraulic oil fill cap and remove the drain
plugs on the bottom of the tank.
5. Loosen hose fittings on cylinders and drain as much
fluid as feasible.
6. Replace and tighten all fittings, plugs and caps. Clean
up all spilled oil, and wipe off fittings.
7. Refill the tank with approx. 24 gallons of oil.
Hydraulics - Start Up Procedure
Diagram Action Step Comments
1. Check All Fittings on hose and tube connections.
Make sure all fittings are tight to prevent fluid leakage
and keep air from entering the system.
2. Fill Reservoir with the proper fluid (see “System Fluid
Spec i fi ca tions”). It should be passed through a 10
micron (nom i nal) non-bypass filter prior to entering
the reservoir. Never reuse fluid. Check reservoir drain
plug for leaking. Install charge pressure gauge.
3. Supply 10 PSI Maximum Compressed Air to the
reservoir while sealing the reservoir fill neck with a rag
held in your hand. The pressure will push or force the
hydraulic fluid into the system.
4. Loosen Case Drain Connection at Motors, to bleed
the system of any entrapped air. This allows the pump
Maintenance
NOTICE
Dispose of drained oil according to local
environment protection regulations.
NOTICE
Hydraulic filters need to be changed after the first
100 hours of operation. Change the filters any time
the hydraulic filter restriction lamp lights up, and
after every 250 hours of operation.
Keep the insides of all hydraulic components clean
as they are installed. Always keep the hydraulic oil
clean. Severe machine damage will likely occur if
oil becomes dirty.
The machine must not be operated without the
filters in place, or severe damage to the major
hydraulic components will likely occur.

NOTICE
Prior to filling with fluid, make certain all system
components (reservoir, hoses, valves, fittings,
pump, etc.) are clean.
Care must be taken to not run pump or hydraulic
motor without a sufficient amount of fluid in them.
