GENERAL SAFETY RULES
(For All Battery Operated Tools)
WARNING! Read and understand all instructions. Failure
to follow
all instructions listed below, may result in electric
shock, fire andlor serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
*Keep your work area clean and well lit. Cluttered benches and dark areas invite
accidents.
Do not operate power tools inexplosive atmospheres, such as inthe presence
of flammableliquids, gases, or dust. Powertools create sparks which may ignite
the dust or fumes.
Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
A batteryoperatedtoolwithintegralbatteriesor a separate battery packmust
be recharged only
with the specified charger for the battery. A charger that
may be suitable for one type of battery may create a risk of fire when used with
another battery.
Use batteryoperated tool only with specifically designated battery pack. Use
of any other batteries may create a risk of fire.
Personal Safety
Stay alert, watchwhat you are doing, and use common sense when operating
a power tool. Do not usetool while tired or under the influence of drugs, alcohol,
or medication.
A moment of inattention while operating power tools may result
in serious personal injury.
Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep
your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry,
or long hair can be caught
in moving parts.
Avoid accidental starting. Be sure switchisinthe locked or off position before
inserting battery pack. Carrying tools withyour finger onthe switchor inserting
the battery pack into a tool
with the switch on invites accidents.
Remove adjusting keys or wrenches before turning the tool on. A wrench or
a keythat is left attachedtoa rotating part of the
tool may result inpersonalinjury.
Donot overreach. Keep proper footing and balance at all times. Proper footing
and balance enable better control
of the tool in unexpected situations.
Usesafety equipment. Always wear eye protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must be used for appropriate conditions.
2

Tool Use and Care
Use clamps or other practical way to secure and support the workpiece to a
stable platform. Holdingthe work by hand or against your body is unstable and
may lead to
loss of control.
*Do not force tool. Use the correct tool for your application. The correct tool
will do the job better and safer at the rate for which it is designed.
.Do not use tool if switch does not turn
it on or off. A tool that cannot be
controlled with the switch is dangerous and must be repaired.
Disconnect battery pack from tool or place the switch in the locked or off
position before making any adjustments, changing accessories,
or storing the
tool. Such preventive safety measures reduce the risk of starting the tool
accidenta
I I y.
Store idletools out of reach of children and other untrained persons. Tools are
dangerous
in the hands of untrained users.
When battery pack is not in use, keep it away from other metal objects like:
paper clips, coins, keys, nails, screws, or other small metal objects that can
make aconnectionfrom oneterminal toanother. Shortingthe battery terminals
together may cause sparks, burns, or a fire.
Maintaintools with care. Keepcutting tools sharpand clean. Properly maintained
tools with sharp cutting edge are less likely to bind and are easier to control.
Check for misalignmentor binding of moving parts, breakage of parts, andany
other conditionthat may affect the tool's operation.
If damaged, have the tool
serviced before using. Many accidents are caused by poorly maintainedtools.
Use only accessories that are recommended by the manufacturer for your
model. Accessories
that may be suitable for one tool may create a risk of injury
when used on another tool.
Service
Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel may result
in a risk of injury.
When servicing a tool, use only identicalreplacement parts. Follow instructions
inthe Maintenance sectionof this manual, Useof unauthorized parts or failure
to follow Maintenance Instructions may create a risk of shock or injury.

FUNCTIONALDESCRIPTION
Charging
Your newbattery cartridge is not charged.
You
will needto charge it before use. Use
the high capacity battery charger Model
DC1801 to chargethe battery cartridge.
Plug the high capacity battery 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 high capacity
battery charger. Insert the cartridge fully
intothe port
so that it rests on thecharger portfloor.
When the batterycartridge is inserted, the charging lightcolor will change from green to
redandcharging
will begin. The charging lightwill remain lit steadily during charging.
When the charginglight color changesfrom red to green, the chargingcycle iscomplete.
The chargingtime is approximately one hour.
If you leavethe batterycartridge in the charger after the chargingcycle is complete, the
charger will switch into its "trickle charge (maintenance charge)" mode which
will last
approximately
24 hours.
After charging, unplugthe charger from the power source.
CAUTION:
The high capacitybattery charger Model DC1801 isfor charging Makita battery cartridge.
Never use
it for other purposes or for other manufacturer's batteries.
When you charge a newbattery cartridge or a battery cartridge which has not been used
for
a long periodof time, it may not accept a full charge. This is a normal conditionand
does not indicate
a problem. You can rechargethe battery cartridge fully after discharg-
ing it completely and rechargingacouple of times.
If you charge a battery cartridge from a just-operated tool or a battery cartridge which
has been left in
a location exposedto direct sunlight or heatfor a longtime, the charging
light may flash in redcolor. If this occurs, wait for
a while. Charging will begin after the
battery cartridge cools. The battery cartridge will cool faster if you remove the battery
cartridge from the high capacity battery charger.
*If the charginglightflashes alternately in green and redcolor, a problem exists and charg-
ing is not possible. The terminals on the charger or battery cartridge are clogged with
dust or the batterycartridge is worn out or damaged.

Tricklecharge (Maintenance charge)
If you leave the battery cartridge in the charger to prevent spontaneous discharging after
full charge, the charger will switch into its "trickle charge (maintenance charge)"
mode
and keepthe battery cartridge fresh and fully charged.
Tipsfor maintaining maximum batterylife
1. Charge the battery cartridge before completely discharged.
Always stop tool operation and charge the battery cartridge when you notice less tool
power
2. Never recharge a fully charged battery cartridge.
Overchargingshortens the battery service life.
3. Chargethe battery cartridge with room temperature at 10°C - 40°C (50°F - 104°F)
Let
a hot battery cartridge cool downbefore charging it.
Adjustingshoe
When the blade loses its cutting efficiency
in orle place along its cutting edge, reposi-
tion the shoe to unitize
a sharp, unusedpor-
tion of its cutting edge. This will help to
lengthen the life of the blade. To reposition
the shoe, loosen the lever and slide the
shoe forward or back to the desired posi-
tion. Then tighten the lever to firmly secure
the shoe.

*Always be sure that the
tool is switchedoff and the battery cartridge is removed before
installing or removingthe blade.

Do not allow the tool to bounce.
Bring the blade into light contact with the
workpiece. First,make
a pilot groove, using
a slower speed. Then use a faster speed to
continue cutting.
If the tool is operated continuously until the battery cartridge has discharged, allow the
tool to rest for
15 minutes beforeproceedingwith a fresh battery.
MAINTENANCE
