Hammer drilling operation

CAUTION:

There is a tremendous and sudden 

twisting force exerted on the tool/drill bit at the 

time of hole breakthrough, when the hole becomes 

clogged with chips and particles, or when striking 

reinforcing rods embedded in the concrete.

First, turn the action mode changing ring so that the arrow 

on the tool body points to the 

 marking. The adjusting 

ring can be aligned in any torque levels for this operation.

Be sure to use a tungsten-carbide tipped drill bit.

Position the drill bit at the desired location for the hole, 

then pull the switch trigger. Do not force the tool. Light 

pressure gives best results. 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.

 Blow-out bulb

After drilling the hole, use the blow-out bulb to clean the 

dust out of the hole.

Drilling operation

First, turn the action mode changing ring so that the arrow 
points to the 

 marking. Then proceed as follows.

Drilling in wood

When drilling in wood, the best results are obtained with wood 

drills equipped with a guide screw. The guide screw makes 

drilling easier by pulling the drill bit into the workpiece.

Drilling in metal

To prevent the drill bit from slipping when starting a hole, make an 

indentation with a center-punch and hammer at the point to be drilled. 

Place the point of the drill bit in the indentation and start drilling.

Use a cutting lubricant when drilling metals. The excep

-

tions are iron and brass which should be drilled dry.

CAUTION:

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.

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.

CAUTION:

If the tool is operated continuously until 

the battery cartridge has discharged, allow the tool to rest 

for 15 minutes before proceeding with a fresh battery.

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.
