injury, always remove the plug from
power source before removing or
installing bits or accessories.
INSTALLING A ROUTER BIT
Place router upside down with the top of the
router resting on the bench. Another option
is to remove the motor from the base before
installing the bit.
1. Remove the chip shield.
2. Press collet lock to stop rotation of
armature shaft. NOTE: It may be
necessary to rotate collet chuck assembly
to engage collet lock (Fig. 1).
3. Next, use the collet wrench to loosen the
collet nut in counter-clockwise direction
(viewed from under the router).
4. Insert the shank of the router bit into the
collet chuck assembly as far as it will go,
then back the shank out until the cutters
are approximately 1/8" to 1/4" away from
the collet nut face.
5. With the router bit inserted and the collet
lock holding the armature shaft, use the
collet wrench to firmly tighten the collet
nut in a clockwise direction (viewed from
under the router). To ensure proper
gripping of the router bit, the shank of the
router bit must be inserted at least 3/4".
When the template guide has been
removed from base, do not use router
bits greater than 2" in diameter as they
will not fit through the sub-base.
To prevent damage to tool, do not tighten
collet nut without a bit.
NOTE: The router bit shank and collet
chuck should be clean and free of dust,
wood, residue and grease before
assembling.
REMOVING THE ROUTER BIT
1. Press collet lock to stop rotation of
armature shaft and turn the collet chuck
assembly in a counter-clockwise
direction.
.
Once the collet chuck assembly is
loosened, continue to turn the collet
chuck assembly until it pulis the collet
free from its taper, and the router bit
can be removed.
NOTE: The collet chuck is self-extracting;
it is NOT necessary to strike the collet chuck
to free the router bit.
