8. IMPACT to ROTATION changeover (Fig. 8)
Shift the change lever between the right and left
positions to switch easily between IMPACT (rotation
and impact) and ROTATION (rotation only),
respectively.
To bore holes in hard materials such as concrete,
stone and tiles, shift the change lever to the right-
hand position (as indicated by the
mark).
The drill bit operates by the combined actions of
impact and rotation.
To bore holes in metal, wood and plastic, shift the
change lever to the left-hand position (as indicated
by the
mark). The drill bit operates by rotational
action only, as in the case of a conventional electric
drill.
