20. REPLACEMENTPARTS. Whenservicing, use only identicalreplacementparts.
21. POLARIZEDPLUGS. To reduce the risk of electric shock, this equipment has
a polarized plug (one blade is wider than the other). This plug
will fit in a
polarized outlet only one way. If the plug does not fit fully in the outlet,
reversethe plug. If it stilldoes notfit, contacta qualified electriciantoinstall
the proper outlet. Do not change the plug in any way.
VOLTAGE WARNING: Beforeconnectingthe tooltoa power source (receptacle,

for the tool can result
in SERIOUS INJURY to the user - as well as damage to
the tool. If in doubt, DO NOT PLUG IN THE TOOL. Using a power source with
voltage less than the nameplate rating is harmful to the motor.

Installing or removing trimmer bit
CAUTION :
Always be sure that the tool is switched off and unplugged before installing or removing
the bit.
Use the hex wrench to loosen the clamp
bolt and lower the
tool base. lnser the bit
all the way intothe collet cone and tighten
the collet nut securely with the two
wrenches.
To remove the bit, follow the installation
procedurein reverse.
CAUTION
:
Do not tighten the collet nut without inserting a bit, or the collet cone will break.
Adjusting depth of cut
Place the tool on a fiat surface. Loosenthe
clamp bolt and move the tool body until
the bitjust touchesthe flat surface.Tighten
the clamp bolt slightly. Place the tool on
its side and loosen the clamp bolt. Move
the tool base untilthe desired depth of cut
is obtained. Depth of cut can be checked
with the scale label
(1 mm or about 3/64"
per graduation) on the tool. Then tighten
the clamp bolt securely.
Bit protrusion
2
Clamp bolt
CAUTION :
Since excessive cutting may cause overload of the motor or difficulty in controlling the
tool, the depth of cut should not be more than 3 mm (1/8") at a pass when cutting
grooves. When you wish tocut grooves more than 3 mm (1/8") deep, make several passes
with progressively deeper bitsettings.

Switch action
To start the tool, move the switch lever
to the
“ON” position. To stop, move the
switch lever to the
“OFF” position.
Operation
*Set the tool base on the workpiece tobe cut without the bitmaking any contact. Then
turn the tool on and wait until the bitattains full speed. Move the tool forward over the
workpiece surface, keeping the tool base flush and advancing smoothly until the cutting
is complete.
0 When doing edge cutting, the workpiece surface should be on the left side of the bit in
the feed direction.

Correct bitfeed direction
NOTE :
0 Moving the tool forward too fast may cause a poor quality of cut, or damage tothe bit
or motor. Moving the tool forward too slowly may burn and mar the cut. The proper
feed rate will depend on the bit
size, the kind of workpiece and depth of cut. Before
beginning the cut on the actual workpiece,
it is advisable to make a sample cut on a
piece of scrap lumber. This will show exactly howthe cut will look as well as enable you
to check dimensions.
When using the straight guide or the trimmer guide, be sure to install it on the right side
inthe feed direction. This will help to keep itflush with the side of the workpiece.

Straight guide (Optional accessory)
The straight guide is effectively used for
straight cuts when chamfering or grooving.
Install the straight guide on the guide
holder with the wing bolt. Then use the
hex wrench
to loosen the bolts on the tool
base and insert the guide holder into the
grooves in the tool base. Adjust the dis-
tance between the
bit and the straight
guide and tighten the bolts securely. When
adjusting the straight guide up or down,
loosen the wing bolt. After adjusting
it,
tighten the wing bolt securely.

When cutting, move the tool with the straight guide flush with the side of the workpiece.
Wider straight guide of desired dimensions
may be made by using the convenient holes
in the guide to bolt on extra pieces of
wood.
