GENERAL SAFETY RULES
(For All Tools)
WARNING! Read and understand all instructions. Failure
to
follow all instructions listed below, may result inelectric
shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
READ ALL INSTRUCTIONS.
1. Keepyour work area cleanand well lit. Cluttered benchesand dark areas invite
accidents.
2. Donotoperate power tools in explosiveatmospheres, suchas in the presence
of flammable liquids, gases, or dust. Power tools create sparks which may
ignite the dust or fumes.
3. Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to loose control.
4. Double Insulatedtools are equipped with a polarizedplug(onebladeis 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 not fit,
contact a qualified electrician to install a polarized outlet. Do not change
the plug
in any way. Double insulation H eliminates the need for the three
wire grounded power cord and grounded power supply system.
5. Avoid body contactwith grounded surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk of electric shock if your body is
grounded.
6. Don't expose power tools to rain or wet conditions. Water entering a power
tool
will increase the risk of electric shock.
7. Do notabuse the cord. Never use the cord tocarry the tools or pullthe plug
from an outlet. Keep cordaway from heat, oil, sharp edges or movingparts.
Replace damaged cords immediately. Damaged cords increase the risk of
electric shock.
8. When operating a powertool outside, usean outdoor extensioncord marked
"W-A" or
"W." These cords are rated for outdoor use and reduce the risk
of electric shock.
9. Stay alert, watch what you are doing and usecommon sense when operating
a power tool. Do not use tool while tired or under the influence of drugs,
alcohol, or medication.
A momentof inattention while operating power tools
may result in serious personal injury.
IO. Dressproperly. Do not wear looseclothing or jewelry. Containlonghair. Keep
your hair, clothing, and glovesawayfrom movingparts. Looseclothes, jewelry
or long hair can be caught in moving parts.

11. Avoid accidental starting. Be sure switchisoff before plugging in. Carrying
tools withyour finger onthe switch or plugging
in tools that have the switch
on invites accidents.
12. Removeadjusting keys or switches before turning the tool on.
A wrench or
a key that is left attached to a rotating part of the tool may result
in personal
injury.
13. Donotoverreach. Keep properfooting andbalanceatalltimes. Proper footing
and balance enables better control of the tool in unexpected situations.
14. Use safety equipment. Always wear eye protection. Dust mask, non-skid
safety shoes, hard hat, or hearing protection must be used for appropriate
conditions.
15. 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.
16. Do notforce 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.
17. Do not use tool
if switch does not turn it on or off. Any tool that cannot
be controlled
with the switch is dangerous and must be repaired.
18. Disconnect the plugfrom the powersource before makingany adjustments,
changing accessories, or storing the
tool. Such preventive safety measures
reduce the risk of starting the tool accidentally.
19. Store idle tools out of reach of children and other untrained persons.
Tools
are dangerous in the hands of untrained users.
20. Maintain tools with care. Keep cutting tools sharp and clean. Properly
maintainedtools, with sharp cutting edges are less likely
to bindand are easier
to control.
21. Check for misalignment or binding of moving parts, breakage of parts, and
any other condition that may affect the tools operation. If damaged, have
the toolservicebefore using. Many accidentsare caused by poorly maintained
tools.
22. Use only accessories that are recommended by the manufacturer for your
model. Accessories that may be suitable for one tool, may become hazardous
when used on another tool.
23.
Tool service must be performed only by qualified repair personnel. Service
or maintenance performed by unqualified personnel could result in a risk of
injury.
24. When servicing a tool. use only identicalreplacement parts. Follow instruc-
tions in the Maintenance section of this manual. Use of unauthorized parts
or failure tofollow Maintenance Instructionsmay create a risk of electric shock
of injury.

SPECIFIC SAFETY RULES FOR ROTARY HAMMER
1. Holdtools by insulatedgripping surfaceswhen performingan operationwhere
the cutting tool may contact hidden wiring or its own cord. Contact with a
"live" wire will make exposed metal parts of the tool "live" and shock the
operator.
2. Wear ear protectors when using the tool for extended periods. Prolonged
exposure
to high intensity noise can cause hearing loss.

Always be sure that the tool is switched off
and unplugged before installing or removing
the bit.
To installthe bit, turn the chapge ring in the
direction
of the arrow until the fi mark on
the change ring
is aligned with the I mark
on the rubber cap. Align the key groove on
the bit shank with the mark on the
rubber cap and insert the bit.

Side grip (auxiliary handle) r
The side grip swings aroundto either side,
allowing easy handling
of the tool in any
position. Loosen the side grip
by turning it
counterclockwise, swing
it to the desired
position and then tighten
it by turning
clockwise.
Depthgauge
The depth gauge is convenient for drilling
holes of uniform depth. Insert the depth
gauge into the hole in the grip base.Adjust
the depth gauge to the desired depth and
then tighten the clamp screw to secure the
depth gauge.
NOTE:
The depth gauge cannot be used at the
position where the depth gauge strikes
againstthe gear housing.
Switchaction
To start the tool, simply pull the trigger.
Tool speed is increased
by increasingpres-
sure on the trigger. Release the trigger to
stop.

Torquelimiter
The torque limiter will actuate when a certain torque level is reached. The motor will
disengagefrom the output shaft. When this happens, the bit will stop turning.
CAUTION:
*As soon as the torque limiter actuates, switch off the tool immediately. This will help
prevent premature wear of the tool.
*Hole saws, core bits, diamond core bits, etc. cannot be used with this tool. They tend to
pinch or catch easily in the hole. This will cause the torque limiter to actuate too
frequently.
Hammer drillingoperation
Position the bit at the desired location for the hole, then pull the trigger. Do not force the
tool. Light pressure gives best results. Keep the tool in position and prevent
it from
slipping away from the hole.
Do not apply more pressure when the hole becomes
clogged with chips or particles. Instead, run the tool at an idle, then remove the bit
partially from the hole.
By repeating this several times, the hole will be cleaned out and
normal drilling maybe resumed.
CAUTION:
There is
a tremendous and sudden twisting force exerted on the tool/bit at the time of
hole breakthrough, when the hole becomes clogged with chips and particles, or when
striking reinforcing rods embedded in the concrete. Always use the side grip (auxiliary
handle) and firmly hold the tool by both side grip and switch handle during operations.
Failure to do
so may result in the loss of control of the tool and potentially severe injury.
Bit grease
Coat the bit shank head beforehand with a small amount (about 0 5 - 1 g, 0 02 - 0 04 02 )
of bit grease This chuck lubricationassures smooth action and longer service life
BloW-Outbulb
Use the blow-out bulb to clean out the
hole
7

Dust cup c
Use the dust cup to prevent dust from fall-
ing over the
tool and on yourself when
performing overhead drilling operations.
Attach the dust cup to the bit as shown in
the figure. The dust cup can be attached
to
the bit up to 14.5 mm (9/16")in diameter.
Drillingin wood or metal
Use the optional drill chuck assembly
(consisting of drill chuck and chuck adapter
assembly). When installing it, refer to
"installing or removing drill bit" described
on the previous page. You can drill up to
13 mm (1/2") diameter in metal and up to
24 mm (15/16")diameter in wood.

brush
is exposed to contact the commutator,
it will automatically shut
off the motor.
When this occurs, both carbon brushes
should be replaced at the same time. Use
only identicalcarbon brushes.
Use
a screwdriverto removethe brush holder
caps. Take out the worn carbon brushes,
insert the new ones and secure the brush
holder caps.

Lubrication
This tool requires no hourly or daily lubrication because it has a grease-packedlubrication
system. Lubricatethe tool every timethe carbon brushes are replaced.
Run the tool for several minutes to warm it up. Switch off and unplug the tool. Remove
the crank cap using a Makita lock nut wrench (optional accessory). Rest the tool on the
table with the bit end pointing upwards. This will allow the old grease the collect inside
the crank housing. Wipe out the
old grease inside and replacewith a fresh grease (30 g;
1 oz). Use only Makita genuine grease (optional accessory). Filling with more than the
specified amount of grease (approx.
30 g; 1 oz) can causefaulty hammering action or tool
failure. Fill only with the specified amount of grease. Reinstall the crank cap and tighten
with the lock nut wrench.
Do not tighten the crank cap excessively. It is made of resin
and issubject to breakage.
