counterclockwise.
Depth gauge
Fig.7
The depth gauge is convenient for drilling holes of
uniform depth. Loosen the side grip and insert the depth
gauge into the hole in the side grip. Adjust the depth
gauge to the desired depth and tighten the side grip.
NOTE:
The depth gauge cannot be used at the position
•
where the depth gauge strikes against the tool
body.

OPERATION

Hammer drilling operation
Always use the side grip (auxiliary handle) and firmly
hold the tool by both side grip and switch handle during
operations.
Fig.8
CAUTION:
There is a 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,
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., move 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.
Blow-out bulb (optional accessory)
Fig.9
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.
Drilling operation
When drilling in wood, metal or plastic materials, move
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.
or when striking

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.
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.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before attempting to perform inspection
or maintenance.
To maintain product SAFETY and RELIABILITY, repairs,
carbon brush inspection and replacement, any other
maintenance or adjustment should be performed by
Makita Authorized Service Centers, always using Makita
replacement parts.
