Assembling and Fitting the Side
Handle (fig. 2A, 2B)

MOUNTING IN FRONT POSITION (FIG. 2A)
1. Snap the steel ring (k) over the collar (x)
behind the tool holder (m). Squeeze both ends
together, mount the bush (l) and insert the pin
(q).
2. Place the side handle clamp (j) and screw on
the clamp wheel (h). Do not tighten.
WARNING: Once assembled, the side
handle clamp should never be removed.
3. Screw the side handle (c) into the bush (l) and
then into clamp wheel. Tighten securely.
4. Rotate the side handle mounting assembly to
the desired position. For drilling horizontally
with a heavy drill bit, we recommend to place
the side handle at an angle of approx. 20° for
optimum control.
5. Lock the side handle mounting assembly in
place by tightening the clamp wheel (h).
MOUNTING IN REAR POSITION (FIG. 2B)
The rear position is particularly useful when drilling
down into a floor.
1. Unscrew the side handle (c) and remove it
from the front position. Leave the side handle
mounting assembly in front position.
2. Screw the side handle directly into one of the
rear side handle positions (i) on either side of the
tool.
