KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.
CONSIDER WORK AREA ENVIRONMENT. Don’t use power tools in damp
or wet locations. Keep work area well
lit. Don’t expose power tools to rain.
Don’t use tool
in presence of flammable liquids or gases.
KEEP CHILDREN AWAY.
All visitors should be kept away from work area.
Don’t let visitors contact tool or extension cord.
STORE IDLETOOLS. When not
in use, tools should be stored in dry, and high
or locked-up place - out of reach of children.
DON’T FORCETOOL.
It will dothejob betterand safer at the ratefor which
it was intended.
USE RIGHT TOOL. Don‘t force small tool or attachment to do the job of a
heavy-duty tool. Don’t use tool for purpose not intended.
DRESS PROPERLY. Don’t wear looseclothingorjewelry. They canbecaught
in moving parts. Rubber gloves and non-skid footwear are recommended
when working outdoors. Wear protectivehair coveringto contain longhair.
USE SAFETY GLASSES. Also use face or dust mask if cutting operation is
dusty.
DON’T ABUSE CORD. Never carry toolby cord or yank
it todisconnect from
receptacle. Keep cord from heat, oil, and sharp edges.
SECURE WORK. Use clamps or a vise to hold work. It’s safer than using
your hand and
it frees both hands to operate tool.
DON’T OVERREACH. Keep proper footing and balance at all times.
MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and
safer performance. Follow instructionsfor lubricating and changingacces-
sories. Inspecttoolcords periodically and if damaged, have repairedbyautho-
rized service facility. Inspect extension cords periodically and replace if
damaged. Keep handles dry, clean, and free from oil and grease.
DISCONNECTTOOLS. When not
in use, before servicing, and when chang-
ing accessories, such as blades, bits, cutters.

14. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keys and adjusting wrenches are removedfromtoolbefore turning
it on.
15. AVOID UNINTENTIONALSTARTING.Don't carry plugged-intool with finger
on switch. Be sure switch is OFF when plugging in.
16. OUTDOOR USEEXTENSION CORDS. Whentool is usedoutdoors, use only
extension cords intended for use outdoors and
so marked.
17. STAY ALERT. Watch what you are doing, use common sense. Don't operate
tool when you are tired.
18. CHECK DAMAGED PARTS. Before further use of the tool, a guard or other
part that is damaged should be carefully checked to determine that
it will
operate properly and performitsintended function. Check for alignment of
movingparts,
binding of movingparts, breakageof parts, mounting, and any
other conditions that may affect its operation. A guard or other part that
is damaged should be properly repaired or replaced by an authorized serv-
ice center unless otherwise indicated elsewhere
in this instruction manual.
Have defective switches replaced by authorized service center. Don't use
tool if switch does not turn
it on and off.
19. GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded
surfaces. For example; pipes, radiators, ranges, refrigerator enclosures.
20. REPLACEMENTPARTS. When servicing, use only identicalreplacement parts.
VOLTAGE WARNING: Before connectingthe tool toa power source (receptacle,
outlet, etc.) be sure the voltage supplied is the same as that specified on the
nameplate of the tool. A power source
with voltage greater than that specified
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.

before operation.
5. Hold the tool firmly.
6. Keep hands away from rotating parts.
7. Makesure the bit is not contacting the workpiece beforethe switch isturned
8. Before using the tool on an actual workpiece, let it run for a while.
9. Be careful of the bit rotating direction and the feed direction.

Installingor removingtrimmer bit
CAUTION :
Always be sure that the tool is switched off and unpluggedbefore installing or removing
the bit.
Insert the bit
all the way into the collet
cone and tighten the collet nut securely
with the two wrenches.
To remove the bit, follow the installation
procedure in reverse.
CAUTION
:
0 Do not tighten the collet nutwithout inserting a bit, or the collet cone will break.
0 Use only the wrenches provided with the tool.
Adjusting bit protrusion
To adjust the bit protrusion, loosen the
clamp screw and move the tool base up or
down
as desired. After adjusting, tighten
the clamp screw firmly to secure the tool
base. On the tool base, there are two sight
windows through which you can read
a
graduation on the scale label. Select a sight
window convenient for your work and
align the scale label with the selected sight
window.

NOTE :
The trimmer shoe is factory installed on the tool.
Use the bolts, wing nuts, spring washers
and flat washers to install the trimmer shoe
as shown at right.

Adjusting amount of chamfering
To adjust the amount of chamfering, loosen the wing nuts and adjust the trimmer shoe.
CAUTION :
With the tool unplugged and switch in the "OFF" position, rotate the collet nut on the
tool several times to be sure that the bit turns freely and does not contact the tool base
or trimmer shoe in any way.
Switch action
To start the tool, move the switch lever
to the "ON" position. To stop, move the
switch lever tothe "OFF" position.
Operation
Turn the tool on without the bit making
any contact with the workpiece and wait
untilthe bit attains full speed. Then move
the tool over the workpiece surface, keep-
ing the tool base and trimmer shoe flush
with the sides
of the workpiece.

When doing edge cutting, the workpiece surface should be on the left side of the bit in
the feed direction.

direction
NOTE :
Moving the tool forward too fast may cause a poor quality of cut, or damage to the 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 how the cut will look as well as enable
you to check dimensions.
When using the trimmer shoe, the straight guide or the trimmer guide, be sure to keep it
on the right side in the feed direction. This will help to keep itflush with the side of the
workpiece.

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.

Straight guide
The straight guide is effectively used for
straight cuts when chamfering or grooving.
Attach the guide plate to the straight guide
with the bolt, the wave washer, the flat
washer and the wing nut.
Loosen the wing bolts and secure the tool
base horizontally. Attach the straight guide
with the clampscrew (A).Loosen the wing
nut on the straight guide and adjust the
distance between the bit and the straight
guide. At the desired distance, tighten the
wing nut securely.

Trimmer guide
Trimming, curvedcuts for furniture and the
like can be done easily with the trimmer
guide. The guide roller rides the curve and
assures
a fine cut.
Loosen the wing bolts and secure the tool
base horizontally. Install the trimmer guide
on the tool base with the clamp screw
(A).
Loosen the clamp screw (6) and adjust the
distance between the bit and the trimmer
guide by turningthe adjusting screw
(1 mm
or about
3/64" per turn). At the desired
distance, tighten the clamp screw (6) to
secure the trimmer guide in place.

Templet guide
The templet guideprovides a sleeve through
which the bit passes, allowing use of the
trimmer with templet patterns.
Remove the tool base fromthe tool.
Loosen the wing bolts and secure the tool
base horizontally. Loosen the two screws
on the tool base.
Place the templet guide on the tool base.
There are four convex portionson the tem-
plet guide. Secure two of the four convex
portions using the two screws. Install the
tool base on the tool.

MAINTENANCE
CAUTION :
Always be sure that the tool is switched off and unpluggedbefore attempting to perform
inspection or maintenance.
Replacingcarbon brushes
I
Remove and check the carbon brushes
regularly. Replacewhen they wear down to
the limit mark. Keep the carbon brushes
clean and free to slip in the holders. Both
carbon brushes should be replaced
at the
same time. Use only Makitacarbonbrushes.
