AIR SUPPLY
The efficiency of the tool is dependent on the proper supply of clean dry air at 90 psig (6.2 bar). The use of a line filter, pressure
regulator, and lubricator will insure maximum output and life of tools. Before connecting tool, blow out the air line to remove water
and dirt which may have accumulated.
HOSE AND HOSE CONNECTIONS
Supply hose should be not less than 3/4" (19.05 mm) I.D. Extension hoses should be at least 3/4" (19.05 mm) I.D. Use couplings
and fittings with at least 3/4" (19.05 mm) I.D. When using quick couplers, install a 6 ft (2m) leader hose between tool and quick
couplers.
LUBRICATION
Use SIOUX No. 288 air motor oil. An airline lubricator, set to deliver 6 to 8 drops per minute, is recommended. If a lubricator is
not used, remove screw from top of handle and fill chamber daily.
Grease hammer mechanism every 40 hours, with up to 1 1/2 oz. (42 1/2 g) of Cat. No. 289A grease, thru grease fitting on rear
of tool. When regreasing hammer mechanism after servicing, use 1 1/2 oz. (42 1/2 g) of Cat. No. 289A grease. Make certain all
moving parts are lubricated.
GENERAL OPERATION
Reversing Spindle Rotation
The direction of spindle rotation is controlled with the reversing lever located ahead of the volume control.
For counterclockwise rotation.
Output Control
The output control is located on the left side of the handle and is graduated from minimum to maximum. The output control valve
controls the torque output in the right and left hand rotation. Turn the output control knob full counter clockwise for maximum output.
Sockets
Use only impact sockets in good shape.
Use deep socket rather than extension bars.
Ensure that the socket is held square to the fastener and that the tool is in-line with the socket.
