Be familiar with the work area.
Always check the work area before using the ratchet wrench.
Keep the work area clean, uncluttered and well lit.

After assembling the socket and connecting the flexible compressed air supply hose, grab the

impact wrench by its "gun" handle.

To adjust the direction of rotation of the wrench it it necessary to push the pin located at the
front (Figure 5 / A), the pressure on this side causes the exiting of the pin from the back

which allows the rotation direction to be inverted (figure 5/B).

F

(FORWARD)

Rotate clockwise to TIGHTEN/SCREW

R

(REVERSE)

Rotate anticlockwise to LOOSEN/UNSCREW

Figure 5 – Adjusting the rotation direction.

Rotate the speed adjustment knob of the wrench (and

the maximum torque) to the desired position, 9
different positions are possible (Figure 6).

“1”

minimum speed

“9”

Figure 6 – Speed adjustment.

To turn on the wrench and begin the rotation of the socket, press the "trigger" lever on the

butterfly valve (Ref. 4 in Figures 2 and 7).
