Intended Use
The tool is intended for heavy chiselling and demolition work as well as for driving and compacting with appropriate accessories.
Power supply
The tool should be connected only to a power supply of the same voltage as
indicated on the nameplate, and can only be operated on single-phase AC
supply. They are double-insulated and can, therefore, also be used from
sockets without earth wire.
General Power Tool Safety Warnings
WARNING: Read all safety warnings, instructions, illustrations and
specifications provided with this power tool. Failure to follow all
instructions listed below may result in electric shock, fire and/or serious
injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded)
power tool or battery-operated (cordless) power tool.
Electric Breaker safety warnings
Safety instructions for all operations
- Wear ear protectors. Exposure to noise can cause hearing loss.
- Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
- Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
Additional safety warnings
- Wear a hard hat (safety helmet), safety glasses and/or face shield. Ordinary eye or sun glasses are NOT safety glasses. 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 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 a while by operating it under no load. This will loosen up the lubrication. Without proper warmup, hammering operation is difficult.
- Always be sure you have a firm footing. Be sure no one is below when using the tool in high locations.
- 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 any one in the area when operating. The bit could fly out and injure someone seriously.
- Do not touch the bit, parts close to the bit, or workpiece immediately after operation; they may be extremely hot and could burn your skin.
- Some material contains chemicals which may be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.
- Do not touch the power plug with wet hands.
- Before operation, make sure that there is no buried object such as electric pipe, water pipe or gas pipe in the working area. Otherwise, the bit may touch them, resulting an electric shock, electrical leakage or gas leak.
- Do not operate the tool at no-load unnecessarily.
SAVE THESE INSTRUCTIONS.
WARNING :
DO NOT let comfort or familiarity with product (gained from repeated use)
replace strict adherence to safety rules for the subject product. MISUSE or
failure to follow the safety rules stated in this instruction manual may cause
serious personal injury.
FUNCTIONAL DESCRIPTION
CAUTION:
- Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool.
Switch action (Fig. 1)
CAUTION:
- Before plugging in the tool, always check to see that the switch lever actuates properly and returns to the “OFF” position when released.
- Do not tape, tie or otherwise secure the switch lever in the “ON” position.
To start the tool, simply squeeze the switch lever. Release the switch lever
to stop.
ASSEMBLY
CAUTION:
- Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.
Installing grip (Fig. 2)
Install the grip securely with the bolts using the hex wrench.
Installing or removing the bit (Fig. 3 & 4) Turn up the tool retainer. With
the notched portion of the bit facing the tool retainer, insert the bit into
the tool barrel as far as it will go.
Return the tool retainer to its original position to secure the bit.
To remove the bit, follow the installation procedure in reverse.
OPERATION
Chipping/Scaling/Demolition (Fig. 5)
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.
- Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.
Lubrication (Fig. 6 & 7)
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.
First, switch off and unplug the tool.
Remove the plate 50 using a screwdriver, then replenish with fresh grease (60
g). Use only Makita genuine hammer grease (optional accessory). Filling with
more than the specified amount of grease (approx. 60 g) can cause faulty
hammering action or tool failure. Fill only with the specified amount of
grease.
Reinstall the plate 50 and secure with the screws.
To maintain product SAFETY and RELIABILITY, repairs, carbon brush inspection
and replacement, any other maintenance or adjustment should be performed by
Makita Authorized or Factory Service Centers, always using Makita replacement
parts.

The use of any other accessories or attachments might present a risk of injury to persons. Only use accessory or attachment for its stated purpose.
If you need any assistance for more details regarding these accessories, ask your local Makita Service Center.

ENG905-1
Noise
The typical A-weighted noise level determined according to EN62841-2-6:
Sound pressure level (LpA): 83 dB (A)
Sound power level (LWA): 103 dB (A)
Uncertainty (K): 1.35 dB (A)
NOTE :
- The declared noise emission value(s) has been measured in accordance with a standard test method and may be used for comparing one tool with another.
- The declared noise emission value(s) may also be used in a preliminary assessment of exposure.
WARNING:
- Wear ear protection.
- The noise emission during actual use of the power tool can differ from the declared value(s) depending on the ways in which the tool is used especially what kind of workpiece is processed.
- Be sure to identify safety measures to protect the operator that are based on an estimation of exposure in the actual conditions of use (taking account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger time).
Vibration
The vibration total value (tri-axial vector sum) determined
according to EN62841-2-6:
Work mode: chiseling
Vibration emission (ah, CHeq): 19.4 m/s2
Uncertainty (K): 1.5 m/s
NOTE :
- The declared vibration total value(s) has been measured in accordance with a standard test method and may be used for comparing one tool with another.
- The declared vibration total value(s) may also be used in a preliminary assessment of exposure.
WARNING :
- The vibration emission during actual use of the power tool can differ from the declared value(s) depending on the ways in which the tool is used especially what kind of workpiece is processed.
