SAFETY INSTRUCTIONS ENA001-2
WARNING:
When using electric tools, basic safety precautions, including the following,
should always be followed to reduce the risk of fire, electric shock and
personal injury. Read all these instructions before operating this product
and save these instructions.
For safe operations:
1. Keep work area clean.
Cluttered areas and benches invite injuries.
2. Consider work area environment.
Do not expose power tools to rain. Do not use
power tools in damp or wet locations. Keep work
area well lit. Do not use power tools where there is
risk to cause fire or explosion.
3. Guard against electric shock.
Avoid body contact with earthed or grounded sur-
faces (e.g. pipes, radiators, ranges, refrigerators).
4. Keep children away.
Do not let visitors touch the tool or extension cord.
All visitors should be kept away from work area.
5. Store idle tools.
When not in use, tools should be stored in a dry,
high or locked up place, out of reach of children.
6. Do not force the tool.
It will do the job better and safer at the rate for which
it was intended.
7. Use the right tool.
Do not force small tools or attachments to do the job
of a heavy duty tool. Do not use tools for purposes
not intended; for example, do not use circular saws
to cut tree limbs or logs.
8. Dress properly.
Do not wear loose clothing or jewellery, they can be
caught in moving parts. Rubber gloves and non-skid
footwear are recommended when working outdoors.
Wear protecting hair covering to contain long hair.
9. Use safety glasses and hearing protection.
Also use face or dust mask if the cutting operation is
dusty.
10. Connect dust extraction equipment.
If devices are provided for the connection of dust
extraction and collection facilities ensure these are
connected and properly used.
11. Do not abuse the cord.
Never carry the tool by the cord or yank it to discon-
nect it from the socket. Keep the cord away from
heat, oil and sharp edges.
12. Secure work.
Use clamps or a vice to hold the work. It is safer
than using your hand and it frees both hands to
operate the tool.
13. Do not overreach.
Keep proper footing and balance at all times.
14. Maintain tools with care.
Keep cutting tools sharp and clean for better and
safer performance. Follow instructions for lubrica-
tion and changing accessories. Inspect tool cord
periodically and if damaged have it repaired by an
authorized service facility. Inspect extension cords
periodically and replace, if damaged. Keep handles
dry, clean and free from oil and grease.
15. Disconnect tools.
When not in use, before servicing and when chang-
ing accessories such as blades, bits and cutters.
16. Remove adjusting keys and wrenches.
Form the habit of checking to see that keys and
adjusting wrenches are removed from the tool
before turning it on.
17. Avoid unintentional starting.
Do not carry a plugged-in tool with a finger on the
switch. Ensure switch is off when plugging in.
18. Use outdoor extension leads.
When tool is used outdoors, use only extension
cords intended for outdoor use.
19. Stay alert.
Watch what you are doing. Use common sense. Do
not operate tool when you are tired.
20. 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
its intended function. Check for alignment of moving
parts, free running of moving parts, breakage of
parts, mounting and any other conditions that may
affect its operation. A guard or other part that is
damaged should be properly repaired or replaced
by an authorized service center unless otherwise
indicated in this instruction manual. Have defective
switches replaced by an authorized service facility.
Do not use the tool if the switch does not turn it on
and off.
21. Warning.
The use of any accessory or attachment, other than
those recommended in this instruction manual or
the catalog, may present a risk of personal injury.
22. Have your tool repaired by a qualified person.
This electric tool is in accordance with the relevant
safety requirements. Repairs should only be carried
out by qualified persons using original spare parts,
otherwise this may result in considerable danger to
the user.

ADDITIONAL SAFETY RULES FOR TOOL ENB009-1
1. Hold tools by insulated gripping surfaces when
performing an operation where the cutting tool
may contact hidden wiring or its own cord. Con-
tact 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.
3. Wear a hard hat (safety helmet), safety glasses
and/or face shield. It is also highly recom-
mended that you wear a dust mask and thickly
padded gloves.
4. Be sure the bit is secured in place before opera-
tion.
5. Under normal operation, the tool is designed to
produce vibration. The screws can come loose
easily, causing a breakdown or accident. Check
tightness of screws carefully before operation.
6. In cold weather or when the tool has not been
used for a long time, let the tool warm up for a
while by operating it under no load. This will
loosen up the lubrication. Without proper warm-
up, hammering operation is difficult.
7. Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
8. Hold the tool firmly with both hands.
9. Keep hands away from moving parts.
10. Do not leave the tool running. Operate the tool
only when hand-held.
11. Do not point the tool at any one in the area when
operating. The bit could fly out and injure some-
one seriously.
12. Do not touch the bit or parts close to the bit
immediately after operation; they may be
extremely hot and could burn your skin.

and turn it a full 180 degrees. Then release it to secure the bit.
To remove the bit, follow the installation procedure in reverse.
OPERATION Chipping/Scaling/Demolition
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 the efficiency.
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 car-
bon brushes should be replaced. Keep the carbon brushes clean and free to
slip in the holders. Both carbon brushes should be replaced at the same time.
Use only identical carbon brushes.

Use a hex wrench to remove the rear 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. It should be relubricated after every 6 months of
operation. Send the complete tool to Makita Authorized or Factory Service
Center for this lubrication service. However, if circumstances require that you
should lubricate it by yourself, proceed as follows.
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 35 (optional accessory).
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 with a fresh grease (30 g; 1 oz).
Use only Makita genuine hammer grease (optional accessory). Filling with
more than the specified amount of grease (approx. 30 g; 1 oz) can cause faulty
hammering action or tool failure. Fill only with the specified amount of grease.
Reinstall the crank cap and tighten with the lock nut wrench.
CAUTION:
•Do not tighten the crank cap excessively. It is made of resin and is
subject to breakage.
To maintain product SAFETY and RELIABILITY, repairs, any other mainte-
nance or adjustment should be performed by Makita Authorized Service Cent-
ers, always using Makita replacement parts.
