H8508 Hydraulic Impact Wrench
4455 Boeing Dr., Rockford, IL 61109-2988 815/397-7070
Operation (cont’d)
Pre-Operation (See Figure 1)
1.
Stop the power source. Disconnect tool from power
source.
2.
Set Open-Center/Closed-Center spool (4) to corre-
spond to the power source hydraulic system, that
the tool will be connected to. See Operation -
Setting Tool for Open-Center/Closed-Center
Operation.
3.
Slide desired 1/2" square drive socket onto 1/2"
drive on tool (8) or insert desired bit in quick-change
chuck.
4.
Connect the hydraulic hoses from the power source
to the tool. Start the power source.
5.
It is recommended that the power source be al-
lowed to run (idle) for a few minutes to warm the
hydraulic reservoir fluid. Actuating the tool inter-
mittently will reduce the time required to warm the
fluid to an efficient operating temperature.
Operation (See Figure 1)
1.
Set reversing spool (3) to desired position (forward
or reverse).
Note:
Never shift the reversing spool (3) while the
tool is operating. Always allow the tool to
come to a complete stop before changing
drill direction. Shifting the spool while the
tool is operating may cause internal
tool damage.
2.
Grasp the trigger handle. Place your opposite hand
on the top of the tool. This will allow leverage to be
applied while operating.
3.
To start the wrench, squeeze the trigger (2).
4.
To stop the wrench, release the trigger (2).
5.
After the tool has stopped rotating, lay the wrench
on a flat surface.
6.
When the tool is not in use, stop the power source
to reduce heat and wear on the tool components.
