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 torain.
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 bestoredindry, andhigh
or locked-up place
- out of reach of children.
DON'T FORCETOOL.
It will dothejob better andsafer atthe ratefor which
it was intended.
USE RIGHT TOOL. Don't force small tool or attachment to do thejob of a
heavy-dutytool. Don't usetoolfor purpose not intended; for example, don't
use circular saw for cutting tree limbs
or logs.
DRESSPROPERLY. Don't wear looseclothingorjewelry. They can becaught
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 bycordor 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
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, haverepairedbyautho-
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. REMOVEADJUSTING KEYS AND WRENCHES. Form habit of checking to
seethat keysand adjusting wrenches are removedfromtoolbeforeturning
it on.
15. AVOID UNINTENTIONALSTARTING. Don't carry tool
with finger 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 resultingin
loss of power and overheating. Table 1 shows the
correct size touse depending on cord length and nameplateampere rating.
If
in doubt, use the next heavier gage. The smaller the gage number, the
heavier the cord.

17. OUTDOOR USE EXTENSIONCORDS. When toolisusedoutdoors, use only
extension cords intended for use outdoors and
so marked.
18. STAY ALERT. Watch what 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 itsintended function. Check for alignment of
movingparts,
binding of movingparts, breakageof parts, mounting, andany
other conditions that may affect its operation. A guard or other part that
isdamaged should be properly repaired or replaced by an authorized serv-
ice center unless otherwise indicated 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.
20. GUARDAGAINST ELECTRIC SHOCK. Prevent body contact with grounded
surfaces. For example; pipes, radiators, ranges, refrigerator enclosures.
21. REPLACEMENTPARTS.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,
reversethe plug. If
it still does not fit, contact aqualified electrician toinstall
the proper outlet. Do not change the plug in any way.

VOLTAGE WARNING: Beforeconnecting thetooltoa 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 tothe user - as well as damage to
the tool.
If in doubt, DO NOT PLUG INTHE TOOL. Using a power source with
voltage less than the nameplate rating is harmful to the motor.

CAUTION:
The fast charger Model DC1201 is specifically designed to charge only Makita battery
cartridges. Never use
it for other purposes or for other manufacturer's batteries.
When youcharge anew batterycartridge or a battery cartridge which hasnot beenused
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 rechargethe batterycartridge fully after discharging
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 beenleft in
a locationexposedto direct sunlight or heat for a long time, the charging
light may flash in red color. If this occurs, wait for a while. Charging will begin after the
battery cartridge cools.
If the charging light flashes alternately in green and red color and a tone sound "beep,
beep, beep,
..." for about 20 seconds, a problem exists and charging is not possible. The
terminalson the charger or battery cartridgeare cloggedwithdust or the battery cartridge
is worn out or damaged.
If you wish to charge two battery cartridges, allow 15 minutes between chargings on
the fast charger.
