GENERAL SAFETY RULES
WARNING! Read and understand all instructions. Failure to follow all instructions listed below may result in electric shock, fire and/or serious personal injury.
READ ALL INSTRUCTIONS.
WORK AREA
-
Keep your work area clean and well-lit. Cluttered benches and dark areas invite accidents.
-
Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks that 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 -
Double-insulated tools are equipped with 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, 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 eliminates the need for the three-wire grounded power cord and grounded power supply system.
-
Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded.
-
Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
-
Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep the cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.
-
When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W.” These cords are rated for outdoor use and reduce the risk of electric shock.
PERSONAL SAFETY -
Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tools 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 jewellery. Contains long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
-
Avoid accidental starting. Be sure the switch is off before plugging in. Carrying tools with your finger on the switch or plugging in tools that have the switch on invites accidents.
-
Remove adjusting keys or wrenches 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.
-
Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enable better control of the tool in unexpected situations.
-
Use safety equipment. Always wear eye protection. Dust masks, non-skid safety shoes, hard hats, or hearing protection must be used for appropriate conditions.
TOOL USE AND CARE -
Use clamps or other practical ways to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control.
-
Do not force tools. 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 the tool if the switch does not turn it on or off. Any tool that cannot be controlled with the switch is dangerous and must be repaired.
-
Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.
-
Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.
-
Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools, with sharp cutting edges are less likely to bind and are easier to control.
-
Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool’s operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.
-
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.
SERVICE -
Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury.
-
When servicing a tool, use only identical replacement parts. Follow the instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of electric shock or injury.
SPECIFIC SAFETY RULES FOR ROTARY HAMMER
-
Hold tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.
-
Wear ear protectors when using the tool for extended periods. Prolonged exposure to high-intensity noise can cause hearing loss.
-
Wear a hard hat (safety helmet), safety glasses and a face shield. It is also highly recommended that you wear a dust mask and thickly padded gloves.
-
Be sure the bit is secured in place before operation.
-
Under normal operation, the tool is designed to produce vibration. The screws can come loose easily, causing a breakdown or accident. Check the tightness of screws carefully before operation.
-
In cold weather or when the tool has not been used for a long time, let the tool warm up for several minutes by operating it under no load. This will loosen up the lubrication. Without proper warm-up, the hammering operation is difficult.
Be sure no one is below when using the tool in high locations. -
Always be sure you have a firm footing.
-
Hold the tool firmly with both hands.
-
Keep hands away from moving parts.
-
Do not leave the tool running. Operate the tool only when hand-held.
-
Do not point the tool at anyone in the area when operating. The bit could
-
Do not touch the bit or parts close to the bit immediately after the operation; fly out and injure someone seriously. they may be extremely hot and could burn your skin.

FUNCTIONAL DESCRIPTION
Selecting action mode
When selecting an action mode, first set the change lever and the shift lever
to the position shown on the right. Then proceed as follows.
Rotation with hammering
For drilling in concrete, masonry, etc., depress the lock button and rotate
the change lever so that the pointer points to the symbol. Use the tungsten-
carbide tipped bit.
Hammering only
For chipping, scaling or demolition operations, depress the lock button and
rotate the change lever so that the pointer points to the symbol. Use a bull
point, cold chisel, scaling chisel, etc.
Rotation only
For drilling in wood, metal or plastic materials, rotate the shift lever so
that the symbol is aligned with the pointer on the change lever. Use a twist
drill bit or wood bit.
CAUTION
- Do not rotate the change lever and/or the shift lever when the tool is running under load. The tool will be damaged.
- To avoid rapid wear on the mode change mechanism, be sure that the change lever and/or the shift lever is always positively located in one of the three action mode positions.
- The action mode cannot be changed directly from “hammering only” to “rotation only” or from “rotation only” to “hammering only”. First, set the change lever and the shift lever to the “rotation with hammering” mode position shown on the right. Then set them to the position for “hammering only” or “rotation only”.
Bit angle (when chipping, scaling or demolishing)
CAUTION
Always be sure that the tool is switched off and unplugged before changing the
bit angle.
- The bit can be secured at 12 different angles. To change the bit angle, depress the lock button and rotate the change lever so that the pointer points to the symbol.
- Turn the bit to the desired angle.
- Depress the lock button and rotate the change lever so that the pointer points to the symbol. Then make sure that the bit is securely held in place by turning it slightly.
Side grip
CAUTION
- Always use the side grip to ensure operating safety when drilling in concrete, masonry, etc.
- When the bit begins to break through concrete or if the bit strikes reinforcing rods embedded in concrete, the tool may react dangerously. Maintain good balance and safe footing while holding the tool firmly with both hands to prevent dangerous reactions.
The side grip swings around to 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.
Switch action
CAUTION
Before plugging in the tool, always check to see that the switch trigger
actuates properly and returns to the “OFF” position when released.
- To start the tool, simply pull the trigger.
- Release the trigger to stop.
Speed change
- These revolutions and blows per minute can be adjusted just by turning the adjusting dial.
- The dial is marked 1 (lowest speed) to 6 (full speed). Refer to the table below for the relationship between the number settings on the adjusting dial and the revolutions/blows per minute.
Depth gauge
The depth gauge is convenient for drilling holes of uniform depth. Loosen the
clamp screw and adjust the depth gauge to the desired depth. After adjusting,
tighten the clamp screw firmly.
NOTE
The depth gauge cannot be used at the position where the depth gauge strikes
against the gear housing/motor housing.
Indicator lamp
The green power-ON indicator lamp lights up when the tool is switched ON. If
the indicator lamp is lit but the tool does not start, the carbon brushes may
be worn out, or the electric circuit or the motor may be defective. If the
indicator lamp does not light up and the tool does not start, the ON/OFF
switch or the mains cord may be defective.
The red service indicator lamp lights up when the carbon brushes are nearly
worn out to indicate that the tool needs servicing.
After approx. 8 hours of use, the motor will automatically be shut off
.
ASSEMBLY
Installing or removing a bit
CAUTION
Always be sure that the tool is switched off and unplugged before installing
or removing the bit.
Clean the bit shank and apply the bit grease provided to it before installing
the bit.
- Insert the bit into the tool. Turn the bit and push it in until it engages.
- If the bit cannot be pushed in, remove the bit. Pull the chuck cover down a couple of times. Then insert the bit again. Turn the bit and push it in until it engages.
- After installing, always make sure that the bit is securely held in place by trying to pull it out. To remove the bit, pull the chuck cover down all the way and pull the bit out
OPERATION
Hammer drilling operation
CAUTION
When the bit begins to break through concrete or if the bit strikes
reinforcing rods embedded in concrete, the tool may react dangerously.
Maintain good balance and safe footing while holding the tool firmly with both
hands to prevent dangerous reactions.
Set the change lever and the shift lever to
the symbol. Position the bit at the location for the hole, then pull the
trigger. Do not force the tool. Light pressure gives the 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 it from the hole. By
repeating this several times, the hole will be cleaned out.
Torque limiter
The torque limiter will actuate when a certain torque level is reached. The
motor will disengage from 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.
Chipping/Scaling/Demolition
Set the change lever and the shift lever to the symbol. Hold the tool firmly
with both hands. Turn the tool on and apply slight pressure on the tool so
that the tool will not bounce around, uncontrolled. Pressing very hard on the
tool will not increase efficiency.
Drilling operation
Set the change lever and the shift lever to the symbol.
Drilling in wood
When drilling in wood, best results are obtained with wood drills equipped
with a guide screw. The guide screw makes drilling easier by pulling it into
the workpiece.
Drilling in metal
- To prevent the bit from slipping when starting a hole, make an indentation with a centre punch and hammer at the point to the drilled. Place the point of the bit in the indentation and start drilling.
- Use a cutting lubricant when drilling metals. The exceptions are iron and brass which should be drilled dry.
CAUTION
Pressing excessively on the tool will not speed up the drilling. This
excessive pressure will only serve to damage the tip of your bit, decrease the
tool’s performance and shorten the service life of the tool.
Blow-out bulb (optional accessory)
Use the blow-out bulb to clean out the hole.
Dust cup (optional accessory)
Use the dust cup to prevent dust from falling over the tool and on yourself
when performing overhead drilling operations.
Attach the dust cup to the bit as shown in the figure.
The size of bits to which the dust cup can be attached to is as follows.
Drilling in 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. Set the action mode changing knob to
“rotation only”. You can drill up to 13 mm (1/2″) diameter in metal and up to
30 mm (1-3/16″) diameter in wood.
CAUTION
Never use “rotation with hammering” when the drill chuck assembly is installed
on the tool. The drill chuck assembly may be damaged. Also, the drill chuck
will come off when reversing the tool.
MAINTENANCE
CAUTION
Always be sure that the tool is switched off and unplugged before attempting
to perform inspection or maintenance.
Replacing carbon brushes
When the resin insulating tip inside the carbon 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 identical
carbon brushes.
- Use a screwdriver to remove the brush holder cover.
- Use a screwdriver to remove the 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-packed lubrication system. Lubricate the tool every time the carbon brushes are replaced.
- Run the tool for several minutes to warm it up. Switch off and unplug the tool.
- Loosen the six screws and remove the handle.
- Note that the top screws are different from other screws.
- Disconnect the connector by pulling it.
- Remove the crank cap using a hex wrench.
Rest the tool on the table with the bit end pointing upwards. This will allow
the old grease to collect inside the crank housing. Wipe out the old grease
inside and replace it with fresh grease (30 g). Use only Makita genuine hammer
grease (optional accessory). Filling with more than a specified amount of
grease (approx. 30 g) can cause faulty hammering action or tool failure. Fill
only with the specified amount of grease. Reinstall the crank cap and tighten
it with the hex wrench.
Connect the connector and reinstall the handle.
CAUTION
- Be careful not to damage the terminal or lead wires especially when wiping out the old grease or installing the handle.
- Do not tighten the crank cap excessively. It is made of resin and is subject to breakage.
To maintain product SAFETY and RELIABILITY, repairs, and any other maintenance or adjustment should be performed by Makita Authorized or Factory Service Centers, always using Makita replacement parts.
ACCESSORIES
CAUTION
These accessories or attachments are recommended for use with your Makita tool
