Intended use

The tool is intended for chiseling work in concrete, brick, stone and asphalt 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.

HAMMER 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 RULES

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 or parts close to the bit immediately after operation; they may be extremely hot and could burn your skin.
Do not operate the tool at no-load unnecessarily.
Some material contains chemicals which may be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.

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 trigger actuates properly and returns to the “OFF” position when released.

To start the tool, simply pull the switch trigger. Release the switch trigger to stop. For continuous operation, pull the switch trigger and then push in the lock button.
To stop the tool from the locked position, pull the switch trigger fully, then release it.

ASSEMBLY

CAUTION:

Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.

Installing side grip (auxiliary handle) (Fig. 2)
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.

Bit grease (optional accessory)
Coat the bit shank head beforehand with a small amount of bit grease (about 0.5 – 1 g; 0.02 – 0.04 oz.). This chuck lubrication assures smooth action and longer service life.

Installing or removing bit (Fig. 3 & 4)
Pull the change ring down all the way and insert the bit into the tool holder as far as it will go. Release the change ring and it will return automatically to its original position to secure the bit. 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 change ring down all the way and pull the bit out.

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.
OPERATION

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)

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, 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.

OPTIONAL ACCESSORIES

NOTE:

Some items in the list may be included in the tool package as standard accessories. They may differ from country to country.

Noise
The typical A-weighted noise level determined according to EN62841-2-6:
Sound pressure level (LpA): 86 dB (A)
Sound power level (LWA): 100 dB (A)
Uncertainty (K): 4 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: chiselling
Vibration emission (ah,CHeq): 16.0 m/s2
Uncertainty (K): 1.5 m/s2

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.
