7 Operation

CAUTION
en
In the event of the drill bit sticking, the power tool will
pivot about its own axis. Always use the power tool with
the side handle fitted and hold it securely with both hands
so that the resulting opposing force causes the slip clutch
to release in the event of the drill bit sticking. Use clamps
or a vice to hold the workpiece securely.
7.1 Preparing for use

1. Release the side handle clamping band by turning
the handle counterclockwise.
2. Pivot the side handle into the desired position.
