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, toolsshould bestored in dry, andhigh
or locked-up place
- out of reach of children.
DON'T FORCETOOL.
It will dothejob better and safer atthe ratefor which
it was intended.
USE RIGHT TOOL. Don't force small tool or attachment to do the job
of a
heavy-dutytool. Don't usetool for purpose not intended; for example, don't
use circular saw for cutting tree limbs
or logs.
DRESS PROPERLY. Don't wear looseclothing
or jewelry. They canbecaught
in moving parts. Rubber gloves and non-skid footwear are recommended
when working outdoors. Wear protective hair covering tocontain longhair.
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 todisconnectfrom
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 instructions for lubricatingand changing acces-
sories. Inspecttoolcordsperiodicallyandifdamaged, haverepaired byautho-
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, 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 removed fromtoolbefore turning
it on.
15. AVOID UNINTENTIONALSTARTING. Don't carry toolwithfinger onswitch.
Be sure switch is OFF when plugging in.
16. EXTENSIONCORDS. 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
inlinevoltage resulting in
loss of power and overheating. Table 1 shows the
correct size to use depending on cord length and nameplate ampere rating.
If in doubt, use the next heavier gage. The smaller the gage number, the
heavier the cord.

VOLTAGE WARNING: Beforeconnecting the tool to a power source (receptacle.
outlet, etc.) be sure the voltage supplied is the same as that specified on
the
nameplateof the tool. A power source with voltage greater than that specified
for the toolcan 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.

Charging
Your new batterycartridge is not charged.
You will need to charge
it before use. Use
the fast charger Model
DC1201 to charge
the battery cartridge.
*Plug the fast charger into the proper
A/C
voltage source. The charging light will
flash in green color.
*Insert the battery cartridge
so that the
plus and minus terminals on the battery
cartridge are on the same sides
as their
respective markings on the fast charger.
Insert the cartridge fully into the port
so that it rests on the charger port floor.
*When the battery cartridge
is inserted, the charging light color will charge from green to
red and chargingwill begin. The charging lightwill remian
lit steadily during charging.
*When charging
is completed, the charging light color will change from redtogreen and
a tone will sound steadily for about 5 seconds. The chargingtime is approximately one
hour.
*After charging, unplugthe charger fromthe power source.

CAUTION :
*The fast charger Model DC1201 is for charging Makita battery cartridge. Never use it
for other purposes or for other manufacturer’s batteries.
*When
you charge a new battery cartridge or a battery cartridge which has not been used
for
a long period of time, 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 dis-
charging
it completely and recharging a couple of times.
If you charge a battery cartridge from a just-operated tool or a battery cartridge which
has been left in
a location exposed to direct sunlight or heat for a long time, the charg-
ing light may flash in red color. If this occurs, wait for
a while. Chargingwill begin after
the battery cartridge cools. The battery cartridge will cool faster if you remove the
battery cartridge from the fast charger.
If the charging light flashes alternately in green and red color and a tone sounds “beep,
beep, beep,
. . .” for about 20 seconds, a problem exists and charging is not possible.
The terminals on the charger or battery cartridge are clogged with dust or the battery
cartridge
is worn out or damaged.
0 If youwish to charge two battery cartridges, allow 15 minutes between chargings on the
fast charger.
Selecting correct socket
Always use the correct size socket for boltsand nuts. An incorrect size socket will result
in inaccurate and inconsistent fasteningtorque and/or damage to the bolt or nut. Refer to
accessories section for socket
