Application:
It injects high efficiency into manual chipping, riveting, breaking of concrete and asphalt etc.
Operation Method:
1. Before starting work drain any water from the air tank and blow condensation from the air line. Drain compressor more
frequently in hot humid weather.
2. Always ensure air is turned off before installing or removing tools etc.
3. To install the needle tube, complete with needles. Push the assy on the nose of the tool and screw in fully(hand tight
only).
4. To install a chisel, unscrew the needle tube assy, if fitted and insert chisel into the hole in the end of the nose of the
tool.
5. Place the spring retainer over the chisel and screw on to the nose fully, using the appropriate lug.
6. Once the appropriate tool is fitted, you are ready to start.
7. Turn on the air supply, and check for air leaks, if any are apparent, rectify before proceeding. Ensure the air pressure
is set to 90psi (6.2Bar).
8. Hold the tool with one hand around the handle and the other around the barrel, bring the tool towards the work at an
angle of approx. 60-70°. Depress the trigger and allow the needles /chisel to come into contact with the work.
9. Needle /chisel force can be adjusted by turning the regulator knob.
10. To increase force, turn regulator clockwise and anticlockwise to reduce.
Common Troubleshooting:
Event Appearance Possible Cause Solution
Piston damaged Replace piston
Cylinder damaged Replace cylinder
Air is coming from the air inlet
Rusty motor or clogged with objects Disassemble and repair
Regulator is set at off Adjust regulator
Not
operating No air coming from the air
inlet No air flow Check air system and connections
Not enough air pressure Check air pressure
Air leakage form the tool Check all connect points and
repair
Low
efficiency
Low revolution rate
Disk valve damaged Change the disk valve
