Hex key

Adjusting the zero position
After replacing the drill bits, it is necessary to reset the tool
so that the depth guide (14) reads correctly.
1. Loosen the bevel guide locking knob (10) and swivel the
bevel guide (9) fully open (e.g. 90°).
2. Tighten the locking knob (10)
3. Loosen the depth guide locking knob (15).
4. Place the bottom edge of the face plate (12) against a
rigid surface and push the tool forward until the tips of the
drills are flush with the surface of the face plate.
5. Push the depth guide as far as possible in the direction
away from the face plate and tighten the locking knob
(15).
6. Adjust the position of the zero marker (16) so that it aligns
with the zero position on the depth guide.
Operation
Note.
Ensure that the tool is running before contacting the
work piece.
When operating the dowel joiner, use two hands: one on the
tool body and the other on the handle (8).
Take care to correctly adjust the tool prior to drilling. Set
the bevel angle, depth of cut and the distance of the holes
from the edge of the work piece. It is best to make a test
drilling first in a scrap piece of wood, check the results and
re-adjust the settings if necessary.
Note.
If you want to use only one drill bit in your Dowel
Machine, remove the unwanted drill bit and retaining grub
screw.
Service & Maintenance
Cleaning
Never use water or chemical cleaners to clean your power
tool. Wipe the outside clean with a dry cloth.
Note.
Always ensure that the tool is switched off and the
plug is removed from the power point before making any
adjustments or maintenance procedures. Always wear
sturdy gloves when handling or changing drill bits, as they
can be very sharp.
Regularly check to see if any dust or foreign matter has
entered the grills at the front and rear of the motor and
around the on/off switch. Use a soft brush to remove any
accumulated dust. Wear safety glasses to protect your eyes
whilst cleaning.
Replacing carbon brushes
Always ensure that the tool is switched off and the plug
is removed from the power point before making any
adjustments or maintenance procedures.
1. Regularly check that the carbon brushes are not over
worn and replace if necessary.
2. Unscrew the carbon brush caps (3) located either side of
the body of the tool.
3. Replace the two brush and spring sets taking care to
maintain the same positioning.
4. Replace the brush caps.
General inspection
Regularly check that all the fixing screws are tight. They
may vibrate loose over time.
Repairs
Only an authorised service centre should replace the
cordset or effect other repairs. If the cordset is damaged or
worn, have it repaired or replaced by an authorised service
centre.
