Filling the Hydraulic Fluid Reservoir
The pump is shipped without oil in the hydraulic fluid reservoir. The proper oil to be used is included with the
pump in a separate container. Fill the reservoir as follows:
DANGER
Always use proper eye protection and oil-resistant gloves when handling hydraulic fluid.
1. Make sure that the pump is NOT CONNECTED to the power supply.
2. Ensure that the entire area around the oil filler hole is clean. Any dirt or dust caught in the oil could
damage the polished surfaces and precision-fit components of the pump.
3. Remove the oil filler cap
4. Using a clean funnel with a clean filter, pour the oil into the reservoir. The proper level is 12.7 mm
[0.50 in.] from the top of the oil filler hole.
5.
NOTE
6.
Use only an approved brand of hydraulic oil (see Table 12).

4.3.
Preparing the Hydraulic Connections
1. Clean the areas around the hydraulic connection (oil pod) of the pump and the crimping heads.
2. Clean the areas around all of the hose ends and quick-disconnect couplers.
3. Remove the protector cap from the quick-disconnect coupler of each accessory.
4. Remove the protector cap from the hydraulic connection of the pump.
5. Inspect the threads and fittings for signs of wear or damage, and replace them as needed.
6.
Optional:
Seal the hydraulic connections by coating the threads of the quick-disconnect couplers with a
high-grade, non-hardening sealant.
7.
NOTE
A sealant is preferred, but PTFE tape can be used if only one layer of the tape is applied. If using the tape, apply it carefully to
prevent it from being pinched by the quick disconnect coupler and breaking off inside of the hose. Loose pieces of tape can
travel through the system and obstruct the flow of oil.
