OPERATION
CAUTION:
Always use the side grip (auxiliary handle) and
•
firmly hold the tool by both side grip and switch
handle during operations.

Hammer drilling operation
CAUTION:
There is tremendous and sudden twisting force
•
exerted on the tool/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
operations. Failure to do so may result in the loss
of control of the tool and potentially severe injury.
When drilling in concrete, granite, tile, etc., slide the
action mode changing lever to the position of
to use "rotation with hammering" action.
Be sure to use a tungsten-carbide tipped bit.
Position the 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 bit partially from the hole. By
repeating this several times, the hole will be cleaned out
and normal drilling may be resumed.
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.
Drilling operation
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 bit, decrease
the tool performance and shorten the service life
of the tool.
There is a tremendous force exerted on the tool/bit
•
at the time of hole break through. Hold the tool
firmly and exert care when the bit begins to break
through the workpiece.
A stuck 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.
Always secure small workpieces in a vise or
•
similar hold-down device.
When drilling in wood, metal or plastic materials, slide
the action mode changing lever to the position of
symbol to use "rotation only" action.
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 bit into the
workpiece.
Drilling in metal
To prevent the 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 bit in the
indentation and start drilling. Use a cutting lubricant
when drilling metals. The exceptions are iron and brass
which should be drilled dry.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and
•
unplugged before carrying out any work on the
tool.
symbol
Never use gasoline, benzine, thinner, alcohol or
•
the like. Discoloration, deformation or cracks may
result.
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.
