5.
Always attempt one final cycle to ensure the stall point has been reached.
Loosening procedure
First, set the pump to 10,000 psi. Change the drive and the reaction arm to the loosening mode,
ensuring the reaction arm abuts squarely off a solid reaction point. Press and hold the pump
advance button down. Pressure will decrease as the socket beings to turn. As the cylinder
extends fully, you will hear a click. Release the remote control button, and the cylinder
automatically retracts, at which time you again hear the click. Repeat this process until the
fastener can be removed by hand.
NOTE:
If the bolt / nut does not loosen with the above procedure, it is an indication that you
require the next larger size DSX to loosen the bolt.
Lubrication frequency depends on factors known only to the user. The amount of contaminants
in the working area is one factor. Wrenches used in a clean room environment will obviously
require less maintenance than wrenches used outdoors and dropped in loose dirt or sand.
1.
When lubrication is required, lubricate all moving parts.
2.
Springs are used for the drive pawl assembly and for the accuracy assurance pawl.
These springs can be replaced if necessary.
3.
If the cylinder requires disassembly, it is recommended that the cylinder seals be
replaced at the same time. Seal kits are readily available.
4.
Hoses should be checked for cracks and leaks before, and after each job. Hydraulic
fittings can become plugged with dirt and should be flushed periodically.
5.
Fittings should be kept clean and not allowed to be dragged along the ground or floor as
even small particles of dirt can cause the internal valves to malfunction.
All structural parts on the tools should be inspected at least once a year to determine if there are
any cracks, chips, or deformities.
