INSTALLING AND REMOVING BITS
WARNING: Be sure to switch power OFF and disconnect the plug from the
receptacle to avoid serious trouble.
1. Installing bits
(1) Remove the motor housing from base as
follows.
(a) Open the lever. (Fig. 2)
(b) While holding the base, turn the motor
housing counterclockwise.
(c) Turn it until the pin in the base is
disengaged from the groove in the
motor housing. Lift the motor housing
free from the base.
(2) Clean and insert shank of bit into the collet
chunk until shank bottoms, then back it out
approximately 1/16” (approx. 2 mm).
(3) With the bit inserted and 16 mm wrench
holding the armature shaft, use the 23 mm
wrench to firmly tighten the collet chuck in
a clockwise direction (viewed from under
the router). (Fig. 3)
(4) When using the 1/4” diameter shank bit,
replace the equipped collet chuck with the
one for 1/4” diameter shank bit which is
provided as the standard accessory.
CAUTION:
ⅷ Ensure that the collet chuck is firmly
tightened after inserting a bit. Failure to do
so will result in damage to the collet chuck.
