if
damaged. Keep handles dry, clean, and free from oil and grease.
DISCONNECTTOOLS. When not inuse, 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 keysand adjusting wrenches are removed from tool before 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 USE EXTENSIONCORDS. Whentoolis usedoutdoors, use only

17. STAY ALERT. Watchwhat youare doing, use common sense. Don’t operate
tool when you are tired.
18. CHECK DAMAGED PARTS. Beforefurther 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 its intended function. Check for alignment of
movingparts, 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 unlessotherwiseindicated 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

To remove the battery cartridge, pull out
the
set plate on the tool and grasp both
sides of the cartridge while withdrawing
it from the barrel.
0 To insert the battery cartridge, align the
tongue on the battery cartridge with the
groove in the housing and slip it into
place. Snap the
set plate back into place.
Be sure to close the
set platefully before
usingthe tool.
0 Do not use force when inserting the battery cartridge.
If the cartridge does notslide
in easily, it is not beinginserted correctly.
Charging
Plug the fast charger into your power
source. Insert the battery cartridge so that
the plus and minus terminals on the bat-
tery cartridge are on the same sides
as their
respective markings on the fast charger. In-
sert the cartridge fully intothe port
so that
it restson the charger port floor.
The charging light will come on and charg-
ing will begin. Ifthe charging light does not
come on, press the reset button. If the
83
charging light goes out within 10 seconds even after pressingthe reset button a couple of
times, the battery cartridge
is dead. (CAUTION : Wait for more than 5 seconds after the
charging light goes out to press the reset button again.) Replace
it with a new one. When
the ‘charging light goes out after about one hour,
you may remove the fully charged
battery cartridge. After charging, unplugthe charger from the power source.
CAUTION :
0Your new battery cartridge is notcharged. You will need to charge it before use.
0 If you try to charge a cartridge from a just-operatedtool, sometimesthe charginglight
will not come on. If this occurs,
let the cartridge cool off for a while. Then re-insert
it and try tocharge it once more.
0 When you charge a new battery cartridge or a battery cartridge which has not been used
for
a long period, it may not accept a full charge. This is a normal condition and does
not indicate
a problem. You can recharge the battery cartridge fully after discharging
it almost completely a couple of times.
0 If youwish tocharge two battery cartridges, allow 15 minutes between chargings on the
fast charger.

Installingor removing trimmer bit
CAUTION
:
Always be sure that the tool is switched off and the battery cartridge is removedbefore
installingor removing the bit.
To install the straight bit6, insert
it all the
way into the collet cone and tighten the
collet nutsecurely with the two wrenches.
To install the straight bit3, first insert the
adapter
all the way into the collet cone,
then insert the bit
all the way into the
adapter. Tighten the collet nut securely
with the two wrenches. To removethe bit,
follow the installation procedure in reverse.
NOTE
:
To perform effective operation, the straight bit3 is recommendedonly for cutting off or
cutting out the plaster board. The straight bit6 is used for other operations.
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 clamp screw and move the tool body
until the bit just touches the flat surface.
Tighten the clamp screw slightly. Place the
tool on
its side and loosenthe clamp screw.
Move the tool base until the desired depth
of cut is obtained. Depth of cut can be
checked with the scale label
(2 mm or
about 5/64" per graduation) on the tool.
The tighten the clamp screw securely.
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 mm (3/16")
at a pass when cutting
grooves. When you wish to cut grooves more than 5 mm (3/16") deep, make several
passes with progressively deeper bitsettings.

Adjusting side base
This tool is equipped with an adjustable
side base.
To makethe side base flush with
the tool base, loosen the wing bolt and
set
the tool on a level place. Then tighten the
wing bolt securely.
Switch action
To start the tool, move the slide switch
up. Move
it down to stop.

Operation
oset the tool base on the workpiece tobe cut without the bit making 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 advancingsmoothly 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. (Seethe figure below.)
Feed direction
(View from
the top of the tool)
(3 Bit revolving
direction
I Correct bit feed 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
pieceof scrap lumber. This will show exactly how the cutwill look as well as enableyou
to check dimensions.
.When using the straight guide
or the trimmer guide, be sure to install it on the rightside
inthe feed direction. This will help to keep
it flush with the side of the workpiece.
CAUTION :
If the tool is operated continuously until the battery cartridge has discharged, allow the
tool to restfor 15 minutes before proceedingwith a fresh battery.
