6.1. Storage
NEVER store the pump without having the protector cap installed or a hydraulic hose and crimping heads
attached to the hydraulic connection. The pump should be stored in a clean, dry area with low humidity
noncondensing). Check for proper pump function after storage.
6.2. Hydraulic Fluid Reservoir
Checking Oil Level and Refilling the Reservoir
CAUTION
Air can accumulate in the hydraulic system if the oil level is too low. This accumulation causes the cylinders to respond in an
unstable or slow manner.
Check the hydraulic oil level in the hydraulic fluid reservoir of the pump after each 10 hours of operating
the pump. Proceed as follows:
Depress the DUMP switch to fully retract the cylinders of the crimping heads.
Clean the entire area around the oil filler cap. Any dirt or dust caught in the oil could damage the
polished surfaces and precision-fit components of the pump.
Remove the oil filler cap. Check that the oil level is 12.7 mm [.50 in.] from the top of the oil filler hole.
If additional oil is needed, proceed as follows:
1. Depress the DUMP switch to release the pressure from the system, then DISCONNECT the pump
from the power supply. Make sure that the cylinders are retracted.
DANGER
The cylinders must be fully retracted before replenishing the oil. Overfills can cause personal injury due to excess reservoir
pressure created if the cylinders are not retracted.
2. Pour oil into the hydraulic fluid reservoir using a clean funnel with a filter. DO NOT exceed the
maximum capacity.
CAUTION
It is essential that the proper grade of oil be used. Refer to Figure 4.
3. Re-install the oil filler cap.
4. Connect the pump to the power supply, and cycle the pump (fully extend and retract the cylinders)
several times, ending with the cylinders retracted.
