Warning : Always wear correct safety clothing, including ear, eye
and lung protection.
The Power Chisel should only be used with two hands, placing the left
hand holding the chisel housing and the right hand holding the tool
body in control of the switch. (as shown in fig.17)
• Use a maximum of 25
o
angle when removing wood. (see fig.18)
• Ensure the machine is running BEFORE contacting the material to be
worked on.
NOTE : The Power Chisel will only work when the chisel
10
is
engaged in the workpiece (this is when the chisel anvil (fig.2)
comes in contact with the cam
5
.
For detailed carving, the Power Chisel can be held as shown in fig.17
• Do not force the tool into the wood at steep angles.
• Do not use the chisels
10
as a lever to break out wood.
Warning : Always ensure that chisels are sharp! Blunt chisels will
not cut and will wear the tool prematurely.
Warning : The chisel shaft becomes very hot during prolonged use.
Only handle by the chisel blade.
Note : Do not cause motor speed to drop by forcing the chisel into
the workpiece. This means you are using too much pressure.
For fast rebates hold the Power Chisel upside down as seen in fig.19
Use only medium pressure. The stroke is delivered at constant power,
speed and length, and will not cut faster by forcing the tool.

securely. If loose, ensure that all screws are securely fitted.
