Secure the workpiece. Use clamps or a vice to hold the
workpiece securely in position. It is then held more
safely and both hands remain free for holding and oper-

7.1 Setting forward or reverse rotation
The forward / reverse switch is used to set the direction
of rotation of the drive spindle. An interlock prevents
operation of the switch while the motor is running.
– Push the forward / reverse switch to the left (as seen
when the tool is in use) = forwards.
– Push the forward / reverse switch to the right (as seen
when the tool is in use) = reverse.
