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: Close the release knob and pump the lever until the target hydraulic pressure is
reached.
Step #5: Once the target pressure is reached, perform the steps required by the tensioner’s
instructions.
Step #6: To relieve the hydraulic pressure, open the release knob to allow the tensioner to fully
retract. The tensioner will take approximately 30 seconds to retract.
It is the best practice to leave the release knob in the open position while the
tensioner is connected to the pump. Even though the pump’s pressure gage reads no
pressure, the tensioner can still be retracting.
5.2 Air‐Driven Pump Operation
The figures 3 and 4 at the end of this manual depict the location of the components used to
operate the hydraulic pump kits.
Refer to the inside cover of the pump for instructions that are specific to the pump. The
following sections are generic instructions that may be superseded by the instructions inside
the pump.
Step #1: Connect the pump to the tensioner with the appropriate hydraulic hose.
WARNING
Check the maximum working pressures of the hoses and tensioners connected to the pump. Do
not exceed the maximum working pressure of the pump, hose, or tensioner.
