Filling the Reservoir for Single Acting and Double Acting Units

1.  Remove the pipe plug from the hydraulic fluid fill hole on the pump.

2.   With the actuator in its normal position (stem extended for double acting), fill the pump reservoir 

approximately 1/2 full with Mobil DTE 24 hydraulic fluid (or equivalent).

3.   Close the pump bypass and hand operate the actuator to its full travel position, adding fluid as necessary to 

maintain the 1/2 full level in the reservoir. This operation assures that the hydraulic cylinder is filled with fluid.

4.  Install breather plug into the hydraulic fluid fill hole after the hydraulic fluid filling procedure.

Do not over fill the reservoir.
