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 loose clothingorjewelry. They can be caught
in moving parts. Rubber gloves and non-skid footwear are recommended
when working outdoors. Wear protective hair covering to contain long hair.
USE SAFETY GLASSES. Also use face or dust mask
if cutting operation is
dusty.
DON'T ABUSE CORD. Never carry tool by 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

rized service facility. Inspect extension cords periodically and replace if
damaged. Keep handles dry, clean, and free from oil and grease.
DISCONNECTTOOLS. When not inuse, beforeservicing, and when chang-
ing accessories, such as blades, bits, cutters.

14. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keysand adjusting wrenches are removedfromtool before turning
it on.
15. AVOID UNINTENTIONALSTARTING. Don't carry plugged-in tool withfinger
on switch. Be sure switch is OFF when plugging in.
16. OUTDOOR USE EXTENSIONCORDS. Whentool is used outdoors, use only
extension cords intended for use outdoors and
so marked.
17. STAY ALERT. Watchwhat 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 perform itsintended function. Check for alignment of
moving parts, binding of moving parts, breakage of 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
service center unless otherwise indicated elsewhere in this instruction
manual. Have defective switches replacedby 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. REPLACEMENT PARTS. When servicing, useonly identicalreplacementparts.
21. POLARIZEDPLUGS. To reducethe 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,
reverse the plug. If
it stilldoes notfit, contact a qualified electrician to install
the proper outlet.
Do not change the plug in any way.
VOLTAGE WARNING: Before connecting the tool to a 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.

ADDITIONAL SAFETY RULES
1. Handle the bits very carefully.
2. Check the bit carefully for cracks or damage before operation. Replace
3. Avoid cutting nails. Inspect for and remove all nails from the workpiece be-
4. Hold the tool firmly with both hands.
5. Keep hands away from rotating parts.
6. Make sure the bit is not contacting the workpiece before the switch isturned
on.
7. Before using the tool on an actual workpiece, let it run for a while. Watch
for vibration or wobbling that could indicate improperly installed bit.
8. Be careful of the bit rotating direction and the feed direction. (cf. P. 7)
9. Do not leave the tool running. Operate the tool only when hand-held.
IO. Always switch off and wait for the bit to come to a complete stop before
11. Do not touch the bit immediately after operation; it may be extremely hot

Installing or removing router 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 inreverse.
Tighten
t
CAUTION :
Do nottighten the collet nutwithout inserting a bit, or the collet cone will break.
Adjusting depth
of cut
Place the tool on
a flat surface. Loosen the
screw securing the stopper pole.
Loosen the lock lever and lower the tool
body until the bit just touches the flat
surface. Tighten the lock lever to lock the
tool body.
5

Next, lower the stopper pole until it makes
contact with the adjusting hex bolt. Align
the depth pointer with the
"0" graduation.
Raise the stopper pole until the desired depth of cut is obtained. The depth of cut is
indicated on the scale (1 mm or 1/16" per graduation) by the depth pointer. Then tighten
the screw to secure the stopper pole.
Now, your predetermined depth of cut can be obtained by loosening the lock lever and
then lowering the tool body until the stopper pole makes contact with the adjusting hex
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
(5/8") at a pass when cutting grooves with
a (1/4") diameter bit.
[Note: When cutting grooves with an (3/4") diameter bit, the depth of cut should not be
more than (1/4")
at a pass.] When you wish to cut grooves more than (5/8") deep with a
(1/4") diameter bit or more than (1/4") deep with an (3/4") diameter bit, make several
passes with progressivelydeeper bitsettings.
Stopper block
The stopper block has three adjusting hex bolts which raise or lower 0.8 mm (about
1/32") per turn. You can easily obtain three different depths of cut usingthese adjusting
hex bolts without readjustingthe stopper pole.
Adjust the lowest hex bolt to obtain the deepest depth of cut, following the method of
"Adjusting depth of cut". Adjust the two remaining hex bolts to obtain shallower depths
of cut. The differences in height
of these hex bolts are equal tothe differences indepths
of cut.
To adjust the hex bolts, first loosen
the hex nuts on the hex bolts with the wrench and
then turn the hex bolts. After obtaining the desired position, tighten the hex nuts while
holding the hex bolts in the desired position.
The stopper block
is also convenient for makingthree passes with progressivelydeeper bit
settingswhen cutting deep grooves.
6

Adjusting lock lever
The locked position of the lock lever is
adjustable. To adjust it, loosen the lock
lever
3/4 turn and press the center of the
lock lever. The hex nut will come out. Set
the hex nut to the desired position and
tighen the lock lever.
Switch action
To start the tool, simply pull the trigger.
Release the trigger tostop.
CAUTION:
Before plugging in the tool, always check
to
see that the trigger switch actuates pro-
perly and returns to the
"OFF" position
when released.
Operation
*Set the tool base on the workpiece to be cut without the bitmaking any contact. Then
turn
the tool on and wait until the bit attains full speed. Lower the tool body and move
the tool forward over the workpiece surface, keepingthe tool base flush and advancing
smoothly untilthe cutting
is complete.
When doing edge cutting, the workpiece surface should be on the left side of the bit in
the feed direction. (See the figure below)
Feed direction r__-, ~..
///,'/!3it revolving direction 7,
(View from the top of the tool)
v
Correct bit feed 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
pieceof scrap lumber. This will show exactly howthe cut will look as well as enable you
tocheck dimensions.
*When using the straight guide, be sure to install
it on the right side inthe feed direction.
This will help to keep
it flush with the side of the workpiece.
7

Straightguide (optionalaccessory)
The straight guide
is effectively used for
straight cuts when chamfering or grooving.
To install the straight guide, insert the
guide bars into the holes in the tool base.
Adjust the distance between the bit and
the straight guide. At the desired distance,
tighten the wing bolts to secure the straight
guide inplace.
1 J
When cutting, move the tool with the straight guide flush with the side of the workpiece.
If the distance (A) between the side of the
workpiece and the cutting position
is too
wide for the straight guide, or if the side
of the workpiece
is not straight, the
straight guide cannot be used.
In this case,
firmly clamp a straight board to the work-
piece and use
it as a guide against the
router base. Feed the tool in the direction
of the arrow.
8

Templetguide (optionalaccessory)
The templet guide provides
a sleeve through
which the bit passes, allowing use of the
router with templet patterns.
To install the templet guide, loosen the
screws on the tool base, insert the templet
Screw Base plate

guide and then tighten the screws.
1 Templet guide
Secure the templet tothe workpiece. Place
the tool on the templet and move the tool
with the templet guide sliding along the
side of the templet.
MA1NTENANCE
CAUTION :
Always be sure that the tool is switched off and unpluggedbefore attempting to perform
inspection or maintenance.
To maintain product SAFETY and RELlABlLITY, repairs, carbon brush inspection
and replacement, any other maintenance or adjustment should be performed
by Makita
Authorized or Factory Service Centers, always using Makita replacementparts.
