Air Ratchet Operation

FIGURE 1

Warning!  Do not use a “cheater” bar or other extension to increase torque for this tool.
Do not exceed the maximum torque rating on this tool.

Warning!  Disconnect the Ratchet from the air source when attaching and removing
sockets.  There is no safety lock mechanism on this tool; always disconnect from the
air source when not in use.

Refer to the photograph above.

1.

Attach a 3/8” drive socket to the Ratchet Anvil (15).

2.

By following the directions on page 5, attach the Ratchet to the air source hose.

3.

Gently press the Throttle Lever (5) to activate the Ratchet.  Do not force the unit;
allow it to do the work for you.  To change direction (loosen vs. tighten), stop the tool
and move it away from the workpiece, then turn the Reverse Switch (13).

4.

To adjust the torque, re-adjust the air pressure by changing the setting on the compressor.

Do not exceed the maximum air pressure of 90 PSI for this tool at any time.

5.

When you are finished working, turn off the compressor and disconnect the air source
hose.

Warning!  

There may still be air in the Ratchet.  Squeeze the Throttle Lever (5) and activate the

Ratchet to expel any air still inside the tool.

6.

Remove the socket.

Warning!

  Always disconnect the Ratchet from the air source hose before attempting any

maintenance.

1.

Wipe the unit down with a lint free cloth.

2.

Periodically apply a high grade, light machine oil to the Trigger Pivot area (see above).

3.

Make sure the Ratchet Anvil (15), the Air Inlet (01), and the Reverse Switch (13) are
clear of grease, dirt, or debris.
