Maintenance:
Frequently inspect all system components for leaks
or damage. Electrical components (example; power
cord) may only be repaired or replaced by a qualified
electrician, adhering to all applicable local and national
codes.
Check Oil Level:
Check the oil level of the pump prior to start-up, and add
oil, if necessary, by removing the oil fill plug. Always be
sure the cylinders are fully retracted before adding oil to
the reservoir.
Change Oil and Clean Reservoir:
The ATP III pump oil is a crisp blue color. Frequently
check the oil condition for contamination by comparing
the reservoir oil to new unused oil. As a general rule,
completely drain an clean the reservoir every 250 hours
of use, or more frequently if used in dirty environments
NOTE: This procedure requires that you remove the
pump from the reservoir. Work on a clean bench and
dispose of used oil according to local codes.
1. Unscrew the 13 bolts holding the cover plate to the
reservoir and lift the pump unit out of the reservoir.
Be careful not to damage the filter screen.
2. Pour all oil out of the reservoir.
3. Thoroughly clean the reservoir and magnet with a
suitable cleaning agent.
4.
Remove the pick-up filter screen for cleaning.
CAUTION: Do not pull on the screen or the
bottom of the intake to avoid possible damage.
Clean the screen with solvent and a soft brush.
Reinstall the filter screen.
5. Reassemble the pump and reservoir, installing a
new reservoir gasket.
6. Fill the reservoir with clean manufacturer
recommended hydraulic oil. The reservoir is full
when the oil level is in the middle of the sight gauge,
see Figure 28.
Troubleshooting Guide (see Table B):
Only qualified factory technicians should service the
pump or system components. A system failure may or
may not be the result of a pump malfunction. To determine
the cause of the problem, the complete system must be
included in any diagnostic procedure.
The information contained in Table B is intended for use
as an aid in determining if a problem exists. For repair
