HOW TO USE

1. Adjustment of cutting depth
(1) Loosen the wing nut on the base ass'y.
(2) Move the base ass'y up and down by turning knob
bolt (A) and fit the front end of base with the
pointed end of the bit. (Fig. 3)
(3) Read the value indicated by the top of the base
ass'y. (A in Fig. 4)
(4) Move the base ass'y to the cutting depth.
(5) After moving the base ass'y to the cutting depth,
tighten wing nut securely. (Fig. 4)
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.
3. Base angle adjustment
Loosen the right and left wing bolts and adjust the
base angle. (Fig. 7)
The interval of the embossed graduations is 5˚. Lay
a ruler, etc., along the side of the base for use in
chamfering work.
HOW TO USE GUIDE
NOTE:
Avoid tilting the base when the guide is used.
1. Trimmer guide
Application:
The guide is handy when used in processing of
materials such as trimming and beveling of plywood.
(1) Fit the trimmer guide on the base with knob bolt
(B).
(2) Loosen knob bolt (B) to move the trimmer guide
up and down.
(3) Loosen knob bolt (C) and turn the stop screw to
move the guide pin. (Fig. 8)
After moving the guide pin, tighten knob bolt (C)
to secure it.
(4) When cutting refer to term "Feeding direction" in
"How to use". (Fig. 9)
2. Straight guide
Application:
It is handy when used for linear processing work
such as beveling, grooving and the like.
(1) Fit the straight guide with knob bolt (B) on the base
and fix it.
(2) Adjust the length "B" from the bit to the surface
of straight guide by loosening the knob bolt (D) and
rnoving the straight guide as necessary (Fig. 10)
(3) When cutting refer to term "Feeding direction" in
"How to use". (Fig. 11)
3. Template guide
Application:
It is handy to process with a template a number
of materials in one same shape.
(In this case 6 × 6 mm or 6.35 × 6.35 mm
(1/ 4" × 1/4") straight bit is usable.)
(1) Remove the base ass'y from the main unit.
(2) Loosen the right and left wing bolts and secure the
base horizontally.
(3) Install the template in the recessed part of the base
and secure it with two screws.
NOTE:
Tighten the two screws moderately. Optimum
tightening torque is 10-15 kg-cm.
(4) Install the base ass'y in the main unit. (Fig. 13)
CAUTION
When fit the template guide, the upper part of the
template guide must not touch the collet chuck.
(5) Securely fix the template to the workpiece. Feed the
trimmer following the template. (Fig. 13)
Template
Template is referred to also as profillig mold and
is made from a plywood or a thin wooden plate.
Be careful of the following in producing a
template:
When putting following the inner edge of the
template, the workpiece is cut smaller because
of the distance between the template guide and
bit edge (with a 6 × 6 mm straight bit: 2.0 mm
or 6.35 × 6.35 mm (1/4" × 1/4"): 1.8 mm). By
following the outer edge of the template, the
workpiece is cut larger. (Figs. 14 and 15)
The thickness of the template should be 5 mm
or more.

MAINTENANCE AND INSPECTION

1. Inspecting the bit
Continued use of a dull or damaged bit will result
in reduced cutting efficiency and may cause
overloading of the motor. Replace the bit with a
new one as soon as excessive abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure
to do so could result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the
power tool. Exercise due care to ensure the winding
does not become damaged and/or wet with oil or
water.
4. Inspecting the carbon brushes (Fig. 16)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush can result in motor trouble, replace the carbon
brush with new ones having the same carbon brush
No. shown in the figure when they becomes worn
to or near the "wear limit". In addition, always keep
carbon brushes clean and ensure that they slide
freely within the brush holders.
5. Replacing carbon brushes
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
