OPERATION
CAUTION! Injury Hazard! To avoid injury, always disconnect the air
supply to the tool when attaching or removing sockets or accessories.
Use only sockets and accessories rated for impact use.
1. Disconnect the air supply.
2. Snap the socket or accessory over the retaining ring nested in the
square drive.
3. Connect the air supply, hold the tool securely and press the trigger
to begin the rotating action.
4. To loosen fasteners, move the lever (Fig. 1-1) on the back of the
drive head counter-clockwise to align the
arrow to the reverse arrow (Fig. 1-2).
5. To tighten fasteners, move the lever
clockwise and align the arrow to select
either low (Fig. 1-3), medium (Fig. 1-4),
or high torque (Fig. 1-5) settings (small,
medium or large circles).
PRESSURE DROP
Apply the air consumption and pressure rate numbers to the tool’s air
inlet, not the compressor’s outlet. Calculate the pressure drop for your
air supply set-up and increase the compressor outlet pressure to
compensate. Make sure you do not exceed the maximum pressure for
any part of your air supply system.
Installing a pressure gauge at the tool inlet is the best way to measure
the air pressure and adjust the compressor’s output.
CARE & MAINTENANCE
1. Maintain the tool with care. A tool in good condition is efficient,
easier to control and will have fewer problems.
2. Inspect the tool fittings, alignment and hoses periodically. Have
damaged or worn components repaired or replaced by an authorized
technician. Only use identical replacement parts when servicing.
3. Follow instructions for lubricating and changing accessories.
4. Only use accessories intended for use with this tool.
