Replace the hydraulic oil at one-year intervals, or test after every 500 hours of operation, and
replace when necessary. Testing equipment, kits, and laboratory services are available through
your local Parker Fluid Power Motion & Control Distributor.
CAUTION: OIL MUST BE REPLACED IF IT BECOMES OVERHEATED (HOTTER THAN 140°F, 60°C)
OR CONTAMINATED. FAILURE TO DO SO WILL DAMAGE THE HYDRAULIC PUMP AND/OR OTHER
HYDRAULIC COMPONENTS.
•
Always use clean, filtered hydraulic oil.
•
Filter the oil through a 10-micron (or finer) filter as it is added to the reservoir.
•
Never return spilled oil to the reservoir.
•
Protect the LV1 processor from dirty and dusty environments.
•
Keep the reservoir filler breather cap in place at all times.
NOTE:
When draining oil, do not crack the hydraulic fitting to break the vacuum since this adds
contaminants. Instead remove the filler/breather cap.
Cleaning the Hydraulic Oil Reservoir & Servicing the Suction Strainer
and Return Line Filter
The hydraulic power unit is protected from contamination by a suction strainer and a return line
filter. The suction strainer is located inside the reservoir. To clean the oil reservoir and suction
strainer, proceed as follows:
1.
Vacuum the oil from the reservoir and discard using the supplied transfer pump (10.3425).
To facilitate suction, remove the filler/breather cap.
4.
Disconnect all the hydraulic lines connected to the power pack.
5.
Disconnect the electrical connections to the motor of the power pack.
6.
Disconnect the motor from the vertical wall of the frame.
7.
Remove the power pack from the body of the processor.
8.
Remove the bolts that fasten the reservoir to the motor/pump adapter.
9.
Pull the reservoir from the motor/pump adapter.
10.
Remove the suction strainer from the oil tube attached to the pump.
11.
Wipe out the inside of the oil reservoir with Stoddard solvent or high flash point mineral
spirits. Do this only in an area that is well ventilated. Clean out any debris that may have
collected inside the reservoir.
12.
Locate magnet and clean.
13.
To clean the suction strainer, wash it in high-flash point mineral spirits or Stoddard
solvent. Do this only in an area that is well ventilated.
