Step #2: Follow the tensioner’s instructions on how to install the tensioner.
Step #3: Follow the tensioner’s instructions describing when to pressurize the hydraulic system.
CAUTION
Air can become trapped in the hydraulic system when connecting hoses and tensioners to a
hydraulic pump. Refer to the hydraulic tensioner’s instructions to determine if bleeding the air
out of the hydraulic system is required.
CAUTION
Depending on the amount of air present in the connected hoses or tensioners, it may be
necessary to refill the pump with hydraulic oil.
Step #4: Set the hydraulic pressure to zero by turning the hydraulic pressure control knob
counterclockwise until it stops.
Step #5: Activate the pump’s switch.
Step #6: Slowly turn the hydraulic pressure knob clockwise until the target hydraulic pressure is
reached.
Step #7: Once the target pressure is reached, perform the steps required by the tensioner’s
instructions.
Step #8: Deactivate the pump’s switch to release the hydraulic pressure.
It is the best practice to leave the air‐driven pump connected to the tensioner. Even
though the pump’s pressure gage reads no pressure, the tensioner can still be
retracting.
6.0 Service and Maintenance
6.1 Replacement Hydraulic Oil
Lost oil should be replaced with Enerpac Hydraulic Oil. ISO 32 or equivalent hydraulic oil may be
substituted. Do not overfill the pump’s oil reservoir.
