(For All Tools)
WARNING: WHEN USING ELECTRICTOOLS, BASICSAFETY
PRECAUTIONSSHOULD ALWAYS
BE FOLLOWEDTO REDUCE
THE RISK OF FIRE, ELECTRIC SHOCK, AND PERSONAL
INJURY, INCLUDING THE FOLLOWING:
READ ALL INSTRUCTIONS.
1. KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.
2. 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.
3. KEEP CHILDREN AWAY. All visitors should be kept away from work area.
Don't let visitors contact tool or extension cord.
4. STORE IDLETOOLS. When not in use, tools should be stored in dry, and high
or locked-up place
- out of reach of children.
5. DON'T FORCETOOL. It willdothejob better and safer at the ratefor which
it was intended.
6. USE RIGHT TOOL. Don't force small tool or attachment to do the job of a
heavy-dutytool. Don't use tool for purpose not intended; for example, don't
use circular saw for cutting tree limbs or logs.
7. DRESS PROPERLY. Don't wear loose clothingorjewelry. They can becaught
in moving parts. Rubber gloves and non-skid footwear are recommended
when working outdoors. Wear protective hair coveringtocontain long hair.
8. USE SAFETY GLASSES. Also use face or dust mask if cutting operation is
dusty.
9. DON'T ABUSE CORD. Never carry tool bycord or yank it todisconnect from
receptacle. Keep cord from heat, oil, and sharp edges.
IO. 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.
11. DON'T OVERREACH. Keep proper footing and balance at all times.
12. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and
safer performance. Follow instructionsfor lubricating and changing acces-
sories. Inspect toolcords 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.
13. 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 keys and adjusting wrenches are removed fromtool before turning
it on.
15. AVOID UNINTENTIONALSTARTING. Don't carry toolwithfinger on switch.
Be sure switch is OFF when plugging in.
16. EXTENSION CORDS. Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one heavy enough to carry
the current your product will draw. An undersized cord will cause a drop
in line voltage resulting in loss of power and overheating. Table shows the
correct size touse depending oncord lengthand nameplate ampere rating.
If in doubt, use the next heavier gage. The smaller the gage number,
the
heavier the cord.

18. STAY ALERT. Watchwhat you are doing, use common sense. Don't operate
tool when you are tired.
19. 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 itsintendedfunction. Check for alignment of
moving parts, bindingof moving parts, 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 unlessotherwise indicatedelsewhere inthis instructionmanual.
Have defective switches replaced by authorized service center. Don't use
tool
if switch does not turn it on,and off.
20. GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded
surfaces. For example; pipes, radiators, ranges, refrigerator enclosures.
21 . REPLACEMENT PARTS. When servicing, useonly identicalreplacementparts.
22. 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 still does notfit, contact a qualified electrician toinstall
the proper outlet. Do not change the plug in any way.

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 tool can result inSERIOUS 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.

Installingor removing router bit
CAUTION :
Always be sure that the tool is switched off and unplugged before installing or removing
the bit.
Insert the bit
all the way into the collet
cone. Press the shaft lock to keepthe shaft
stationary and use the wrench to tighten
the collet nut securely. When using smaller
shank bits, first insert the appropriate
collet sleeve into the collet cone, then
install the bit
as mentioned above.
To remove the bit, follow the installation
procedure in reverse.

using
a collet sleeve. Either can leadto breakage of the collet cone.
Adjustingdepth of cut
Place the tool on a flat surface. Loosenthe
lock lever and lower the tool body until
the bit just touches the flat surface. Press
the lock lever down to lock the tool body.
Now lower the stopper pole until it makes
contact with the adjusting hex bolt. The
stopper pole can be moved rapidly by de-
pressing the fast-feed button. Raise the
stopper pole until the desired depth
of cut
is obtained. The depth of cut is equal to
the distance between the stopper pole and
the adjusting hex bolt. Stopper pole travel
can be checked with the scale
(1 mm or 1/16’ per graduation)on the tool body. Minute
depth adjustments can be obtained by turning the stopper pole
(1.5 mm or about 1/16’
per turn). 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.
5

By turning the knob, the upper limit of the
tool body can
be adjusted.When the tip of
the bit
is retracted more than required in
relation to the base plate surface, turn the
knob to lower the upper limit.
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 20 mm (25/32")
at a pass when cutting
grooves. When you wish to cut grooves more than 20 mm (25/32") deep, make several
passes with progressively deeper bit settings.
.Do not lower the knob too low. The bitwill protrudedangerously.
Stopper
The stopper has three adjusting hex bolts
which raise or lower
0.8 mm (about 1/32")
per turn. You can easily obtain three dif-
ferent depths of cut using these 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 dif-
ferences in height of these hex bolts are
equal to the differencesin depths of cut.TO
adjust the hex bolts, first loosen the hex nuts
on the hex boltswith thewrench and then
turn the hex bolts. After obtaining the desired position,tighten the hex nuts while hold-
ing the hex bolts in that desired position. The stopper block
is also convenient for making
three passes with progressively deeper bitsettings when cutting deep grooves.
Switch action
To start the tool, move the switch lever to
the
"ON" position. To stop, move the Switch lever
switch lever to the "OFF" position.
CAUTION
:
0 Make sure the shaft lock is released beforethe switch is turned on.
0 Hold the tool firmly when turning off the tool, to overcome the reaction.

Speed change
This tool allows infinitelyvariable tool speeds from 9,000 to 23,000 rpm. This allows the
bit speed to be adjusted to most ideally match the bit or cutter diameter and the type
of material to be routed. This helps to produce top quality finished surfaces in a wide
variety of materials includinghardwoods, softwoodsor plastics.
Number
To change the tool speed, turn the speed
change knob on the top of the tool. The
tool speed can be adjusted between
9,000
rpm and 23,000 rpm. Numbers from 1 to
5 are indicated on the knob. Faster speeds
are obtained by setting the knob to
a
higher number.

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 how the cut will look as well as enable you
tocheck dimensions.
*When using
the straight guide or the trimmer guide, be sure to install it on the right side
in the feed direction. This will help to keep
it flush with the side of the workpiece.

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
(B). Tighten the
wing bolt
(B) only tight enough to hold
the straight guide temporarily. Then insert
the guide holder into the holes in the tool
base and tighten the wing bolts (A).Adjust
the distance between the bit and the
straight guide by turning the fine adjusting
screw (1.5 mm or about 1/16" per turn).
At the desired distance, tighten the wing
bolt
(B) to secure the straight guide in
place.
When cutting, movethe tool with the straight guide flush with the side of the workpiece.
Wider straight guide of desired dimensions
may be made by using the convenientholes
in the guide to bolt on extra pieces of
wood.
When using
a large diameter bit, attach
pieces of wood to the straight guide which
have
a thickness of more than 15 mm
(5/8")
so that the bit does not strike the
straight guide.

Trimmer guide (Optional accessory)
Trimming,curved cuts in veneers for fur-
niture and the like can be done easily with
the trimmer guide. The guide roller rides
the curve and assures a fine cut.
Install the trimmer guide on the guide
holder with the wing bolt
(B). Tighten the
wing bolt
(6) only tight enough toholdthe
trimmer guide temporarily. Then insert the
guide holder into the holes in the tool base
and tighten the wing bolts (A).Adjust the
distance between the bit and the trimmer
guide by turning the fine adjusting screw
(1.5 mm or about 1 /16’ per turn). At the
desired distance, tighten the wing bolt
(B)
to secure the trimmer guide in place. When
adjusting
