General Power Tool Safety Warnings
WARNING Read all safety warnings and all instructions. Failure to follow
the warnings and instructions may result in electric shock, fire and/or
serious injury.
Save all warnings and instructions for future reference.
HAMMER SAFETY WARNINGS
- 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 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.
- 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.

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.
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.
To start the tool, simply squeeze the switch lever. Release the switch lever to stop.
For model HM1812 only
NOTE:
- Blows at no load per minute becomes smaller than those on load in order to reduce vibration under no load, but this does not show trouble. Once operation starts with a bit against concrete, blows per minute increase. When temperature is low and there is less fluidity in grease, the tool may not have this function even with the motor rotating.
Indicator lamps (Fig. 2)
The green power-ON indicator lamp lights up when the tool is plugged. The
indicator lamp is lit but the tool does not start even if the tool is switched
on, the carbon brushes may be worn out, or the controller, the motor or the
ON/OFF switch may be malfunction.
The red service indicator lamp flickers up when the carbon brushes are nearly
worn out to indicate that the tool needs servicing. After some period of use,
motor will automatically be shut off.
ASSEMBLY
CAUTION:
- Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.
Installing soft grip (Fig. 3 & 4)
Soft grip is NOT installed before factory shipment. Install soft grip
securely. Set the triangle alignment marks on the hammer body and on the soft
grip when installing the soft grip.
Installing or removing the bit (optional accessory) (Fig. 5)
CAUTION:
- Always assure that the bit is securely retained by attempting to pull the bit out of the tool holder after installing the bit.
- Follow the below 2 installation methods in accordance with the 2 different types of bits. If inappropriate installation method is selected, the bit cannot be secured.
This tool accepts bits either with or without a collar on its shank.
To install the bit, follow either procedure (1) or (2) described below.
(1) For bits with a collar (Fig. 6)
Pivot the tool retainer downward (approx. 60 degrees). Insert the bit into the
tool holder until it stops. Return the tool retainer and secure the bit.
(2) For bits without a collar (Fig. 7)
Pivot the tool retainer upward (approx. 60 degrees).
Face the notched portion of the bit upward. Insert the bit into the tool
holder until it stops. Pivot the tool retainer further until it stops at the
tool holder.
To remove the bit, follow the installation procedure in reverse.
OPERATION
Chipping/Scaling/Demolition (Fig. 8)
CAUTION:
- Keep well-balanced posture when holding the heavy tool before / during / after operation to avoid personal injuries.
- Secure debris in case of breaking it into smaller pieces.
- 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.
- Do not pull out the tool if stuck. Instead, break the work around the bit tip.
- Be sure to place the tool on the stable floor or ground after use.
Always use the soft grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations.
MAINTENANCE
CAUTION:
- Store the machine in horizontal position to avoid possible grease leakage.
- Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.
To maintain product safety and reliability, repairs, any maintenance or adjustment should be performed by Makita Authorized Service Centers, always using Makita replacement parts.

Vibration
The vibration total value (tri-axial vector sum) determined according to
EN60745:
Model HM1802
- Work mode: chiselling
- Vibration emission (ah, CHeq): 14.0 m/s2
- Uncertainty (K): 1.5 m/s2
Model HM1812
Work mode: chiselling
Vibration emission (ah, CHeq): 6.5 m/s2

- The declared vibration emission value 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 emission value depending on the ways in which the tool is used.
- 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).
