Chapter 5 Trouble Shooting - Unitronics CP1 Manual

Weekly Maintenance
1. Check oil level in the hydraulic reservoir. If necessary, add oil (AW32)
Quarterly Maintenance
The hydraulic fluid (oil) should be checked for water contamination every three (3) months. This check is
carried out as follows:
1. Turn off the Power Unit for several hours before the test procedure.
2. Wipe off the top of the reservoir carefully. Absolutely no impurities should drop into the reservoir.
3. Remove the Breather Cap.
4. Remove a sample of the oil in the reservoir from the bottom of the tank. This is best done with a
plastic tube and an aspirator bulb, which can siphon off the necessary sample.
5. Check the oil drawn out of the reservoir. If it has a milky white appearance, water is present in the
fluid. If this is the condition of the fluid, the hydraulic system must be drained and flushed.
A compactor should be serviced about every 10,000 cycles. The first password protected display shows the
number of machine cycles. The hydraulic oil should be drained, flushed and refilled with clean oil at least
twice a year. While the reservoir is empty, the suction strainer should be replaced.
NOTE: A certified service representative should carry out this replacement and cleaning
procedure.
