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. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
Safety instructions when using long drill bits with rotary hammers
- Always start drilling at low speed and with the bit tip in contact with the workpiece. At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
- Apply pressure only in direct line with the bit and do not apply excessive pressure. Bits can bend, causing breakage or loss of control, result-ing in personal injury.
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 recom-mended 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 warm-up, 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 inhala-tion and skin contact. Follow material supplier safety data.
- Always be sure that the tool is switched off and the battery cartridge and the bit are removed before handing the tool to other person.
- 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 drill bit/chisel may touch them, resulting an electric shock, electrical leakage or gas leak.
- Do not operate the tool at no-load unnecessarily.
SAVE THESE INSTRUCTIONS.

Turn the dial on the dust case three times after col-lecting every 50,000 mm3
of dust or when you feel the vacuum performance declined.
NOTE: 50,000 mm3 of dust equivalents to drilling 10 holes of ø10 mm and 65 mm depth. Fig.30: 1. Dust case 2. Dial
Disposing of dust
CAUTION: Always be sure that the tool is switched off and the battery
cartridge is removed before carrying out any work on the tool.
CAUTION: Be sure to wear dust mask when disposing of dust.
CAUTION: Be sure that the tool is completely stopped when disposing of dust.
CAUTION: Empty the dust case regularly before the dust case becomes full.
Failure to do so may decrease the dust collection performance and cause dust
inhalation.
CAUTION: The performance of dust collection decreases if the filter in the
dust case become clogged. Replace the filter with new one after approximately
200 times of dust fulfillment as a guide. Failure to do so may cause dust
inhalation.
- Remove the dust case while pressing down the lever of the dust case. ► Fig.31: 1. Lever
- Open the cover of the dust case. ► Fig.32: 1. Cover
- Dispose of the dust, and then clean the filter. ► Fig.33
NOTICE: When cleaning the filter, tap the case of the filter gently by hand to remove dust. Do not tap the filter directly; touch the filter with brush or similar; or blow compressed air on the filter. Doing so may damage the filter.
Replacing filter of dust case
- Remove the dust case while pressing down the lever of the dust case. ► Fig.34: 1. Lever
- Open the filter cover of the dust case. ► Fig.35: 1. Filter cover
- Remove the filter from the filter case. ► Fig.36: 1. Filter 2. Filter case
- Attach a new filter to the filter case, and then attach the filter cover.
- Close the cover of the dust case, and then attach the dust case to the dust collection system.
Replacing sealing cap
- Insert a flat-blade screwdriver into one of the grooves placed on the sides of the nozzle head. Tilt the flat-blade screwdriver at an angle to squeeze and pop the cube hook of the sealing cap out. Then peel the rubber edge of the sealing cap away from the rim of the nozzle head opening. ► Fig.37: 1. Sealing cap 2. Cube hook 3. Groove 4. Nozzle head
- Set one of cube hooks of a new sealing cap into the lower part of the groove in the nozzle head with a recessed surface of the sealing cap facing forward. ► Fig.38: 1. Cube hooks 2. Lower part of the groove 3. Sealing cap 4. Recessed surface
- Place the other hook into the opposite side, while repositioning the sealing cap to fit finely to the nozzle head. ► Fig.39: 1. Sealing cap 2. Cube hook 3. Lower part of the groove 4. Nozzle head 5. Rims
- Gently lay the rubber edge of the sealing cap down over the rim of the nozzle head opening from bottom to top. ► Fig.40: 1. Rubber edge 2. Sealing cap 3. Nozzle head
OPERATION
CAUTION: Always use the side grip (auxiliary handle) and firmly hold the tool
by both side grip and switch handle during operations.
CAUTION: Always make sure that the work-piece is secured before operation.
CAUTION: Do not pull the tool out forcibly even the bit gets stuck. Loss of
control may cause injury.
NOTICE: Before using the dust collection sys-tem with the tool, read the section about the dust collection system.
NOTE: If the battery cartridge is in low temperature, the tool’s capability may not be fully obtained. In this case, warm up the battery cartridge by using the tool with no load for a while to fully obtain the tool’s capability. Fig.41
Hammer drilling operation
CAUTION: There is tremendous and sudden twisting force exerted on the tool/drill bit at the time of hole break-through, when the hole becomes clogged with chips and particles, or when striking reinforcing rods embedded in the concrete. Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during opera-tions. Failure to do so may result in the loss of control of the tool and potentially severe injury.
Set the action mode changing knob to the symbol. Position the drill bit at the
desired location for the hole, then pull the switch trigger.
Apply feed force to the switch handle (main handle) for working accuracy and
efficiency, and hold the side grip (auxiliary handle) to keep balance of the
tool.
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 the drill bit
partially from the hole. By repeating this several times, the hole will be
cleaned out and normal drilling may be resumed.
NOTE: Eccentricity in the drill bit rotation may occur while operating the tool with no load. The tool auto-matically centers itself during operation. This does not affect the drilling precision.
Drilling in wood or metal
CAUTION: Hold the tool firmly and exert care when the drill bit begins to
break through the workpiece. There is a tremendous force exerted on the
tool/drill bit at the time of hole break through.
CAUTION: A stuck drill bit can be removed simply by setting the reversing
switch to reverse rotation in order to back out. However, the tool may back
out abruptly if you do not hold it firmly.
CAUTION: Always secure workpieces in a vise or similar hold-down device.
NOTICE: Never use “rotation with hammering” when the drill chuck is installed
on the tool. The drill chuck may be damaged.
Also, the drill chuck will come off when reversing the tool.
NOTICE: Pressing excessively on the tool will not speed up the drilling. In
fact, this excessive pressure will only serve to damage the tip of your drill
bit, decrease the tool performance and shorten the service life of the tool.
Set the action mode changing knob to the symbol. Attach the chuck adapter to a keyless drill chuck to which 1/2″-20 size screw can be installed, and then install them to the tool. When installing it, refer to the section “Installing or removing drill bit”. Fig.42: 1. Drill chuck assembly 2. Chuck adapter
Blow-out bulb
Optional accessory
After drilling the hole, use the blow-out bulb to clean the dust out of the
hole. Fig.43
Using dust cup set
Optional accessory
Fit the dust cup set against the ceiling when operating the tool. Fig.44
NOTICE: Do not use the dust cup set when drill-ing in metal or similar. It may
damage the dust cup set due to the heat produced by small metal dust or
similar.
NOTICE: Do not install or remove the dust cup set with the drill bit installed
in the tool. It may damage the dust cup set and cause dust leak.
MAINTENANCE
CAUTION: Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance.
NOTICE: Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.
To maintain product SAFETY and RELIABILITY, repairs, any other maintenance or adjustment should be performed by Makita Authorized or Factory Service Centers, always using Makita replacement parts.
