(2) Deeply inset the bit into the collet chuck hole. (The
distance is 15 mm or more from side of collet
chuck.)
(3) Depress spindle lock (Fig. 2) and rotate collet nut
clockwise by hand until lock engages hole in motor
spindle.
(4) While holding spindle lock engaged, tighten collet
nut securely by turning clockwise using wrench

CAUTIONS
Make sure to tighten the collet chuck after inserting
the bit. Collet chuck may be damaged if it is tightened
without inserting the bit.
Avoid depressing the lock pin while the bit is still
in rotation. Because, there is a fear that doing so
may result in an abnormal noise or damage in the
fixed section of the rotating shaft.
(5) Fit the removed base assembly to the rack provided
on the body's outer housing after adjusting the
pinion of the base assembly thereto. Then tighten
the wing nut and fix the assembly securely.
2. Removal of the bit
Loosen the collet chuck in the reverse manner as
described for the fitting the bit.
CAUTION
Bit is heated after the cutting work.
Do not touch it directly.

2. Cutting
It is recommended that the most appropriate guide
be used which is suitable to the type of the work
in order to carry out the work exactly without failure.
(Refer to "How to use guide".) The material to be
processed should be firmly fixed.
(1) Keep the bit separated from the material and hold
the body firmly before switch is turned on. (Fig. 5)
(2) Feeding direction
The bit rotates clockwise as seen from above. Use
the unit by feeding the trimmer in the direction
shown in Fig. 6. If the trimmer is fed in the reverse
direction as shown in the figure, you will receive
reaction of the bit and finishing of the plane to be
cut becomes coarse.
