Operation (cont’d)
Setup (See Figure 1)
1.
Stop the power source. Disconnect tool from power
source.
2.
Set open-center/closed-center spool (4) to
correspond 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 allowed
to run (idle) for a few minutes to warm the hydraulic
reservoir fluid. Actuating the tool intermittently 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.
