DISCONNECT TOOLS. When not in use, before servicing, and when chang-
ing accessories, such as blades, bits, cutters.
REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keys and adjusting wrenches are removedfrom tool beforeturning
it on.
AVOID UNINTENTIONAL STARTING. Don't carry plugged-intool
with finger
on switch. Be sure switch is OFF when plugging in.
OUTDOOR USE EXTENSION CORDS. When tool isusedoutdoors, use only
extension cords intended for use outdoors and so marked.
STAY ALERT. Watch what youare doing, use common sense. Don't operate
tool when you are tired.
CHECK DAMAGED PARTS. Before further use of the tool, a guard or other
part that isdamaged should be carefully checked to determine that
it will
operate properly and perform its intendedfunction. Check for alignment of
movingparts, bindingof movingparts, breakage of parts, mounting, andany
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 indicatedelsewhere 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.
GUARD AGAINST ELECTRIC SHOCK. Prevent body contact
with grounded
surfaces. For example; pipes, radiators, ranges, refrigerator enclosures.
REPLACEMENT PARTS. When servicing, use only identical replacement parts.
VOLTAGE WARNING: Before connecting the 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 toolcan result in SERIOUS INJURY tothe 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 bit
0 Loosen the collet nut and insert the bit
into the chuck hole. Press the shaft lock
and use the wrench tosecurethe bitcare-
fully. Use the collet
sleeve if necessary.
I
CAUTION :
0 Do not tighten the collet chuck without inserting a bit; do not install a small bitwith-
out using
a collet sleeve.
Either can lead to collet chuck breakage.
Adjusting cutting depth
Release the lock lever and lower the tool
to the desired depth. Then pull up on the
lock lever to lock.
Now adjust the stopper
block and pole
so that, even if the lock
lever is released, the router stops at the
uniform depth.
If you press the fast-feed button on the
stopper pole, the pole can be advanced
rapidly.Ordinarily the pole moves
1.5 mm
(1/16”) per turn. Minute depth adjust-
ments can be obtained by raising or
lowering the stopper pole.
5

Stopper block
.The stopper block has an adjustment hex
bolts which move
1 mm (1/32") per turn.
After obtaining the desired depth setting,
tighten the hex nut on the bolt with the
spanner.

Nylon nut
By turning the nylon nut, the upper limit
of the tool can be adjusted.When the tip
of the bit is retractedmore than required
in relation to the base plate surface, turn
the nylon nut to lower the upper limit for
more effective routing.
CAUTION
:
0 Do not lower the nylon nuttoo lowor the bitwill dangerously protrude.
0 Before operating the tool, check to be sure that the router automatically rises to the
upper limit.
Switch action
*To start the tool, position the switch
lever
to "ON" side. To stop, to "OFF"
side.
CAUTION
Prevent accidental starting by making
sure the tool
is switched off before you
plug it in.

Operation
*After switching on the tool, lower the
router, keeping the base plate firmly
against the work surfacewhile routing.
CAUTION
0 When doing edge routing, the workpiece surfaceshould be on the left side of the bitin
the router feed direction or
a dangerous kickback may result.

Correct bit feed direction
0 Adjustment should not be more than 15 mm (5/8") at once when usingstraight bit.
7

Straight guide
.The straight guide is effectively used for
straight cuts when chamfering or groov-
ing. When grooving, the router tends to
pull away to the left in relation to the
feed direction. Install the straight guide
on the right side
to assure a good finished
cut.
.The straight guide with the guide holder
installs on the router by means of the
thumb bolts
A. To obtain the desired dis-
tance between the bit and the straight
guide, turn the fine adjustment screw
(1.5" or 1/16" per turn).Then tighten
the thumb bolt
B to secure the straight
guide inplace.
By bolting larger pieces of wood onto the
straight guide, an even larger (wider)
guide can be obtained as shown.
When using a board-jointing bit, attach
pieces
of wood to the straight guide
which have a thickness of more than
15mm (5/8") so that the bit does not
strike the straightguide.

Trimmer guide
.Trimming, inside work and curvedcuts in
veneers
for furniture and the like can be
done easily with the trimmer guide. The
guide roller rides the curve and assures
a
fine cut.
*The trimmer guide can be attachedto the
guide holder with the thumb bolt
B.
Looseningthe thumb bolt B, the distance
between the bit and the guide surface
can be adjusted by the fine adjustment
screw
(1.5 mm or 1/16" per turn). When
the thumb bolt
C is released, the guide
roller can be moved.

Templet guide
.The templet guide provides a sleeve through which the router bit passes, when making
exact duplicates of
a given pattern (templet). The templet guide is installed by loosen-
ing the two panhead screws on the router base, inserting the templet guide and then
securingthe two screws.

brushes clean and free to slip in the
holders. Both brushes should be changed
at the same time. Use only Makitacarbon
