FUNCTIONAL DESCRIPTION
Switch action
CAUTION:
•
Before plugging in the tool, always check to see
that the switch trigger actuates properly and
returns to the "OFF" position when released.
Fig.5
To start the tool, simply pull the switch trigger. Tool speed is
increased by increasing pressure on the switch trigger.
Release the switch trigger to stop. For continuous operation,
pull the switch trigger, push in the lock button and then
release the switch trigger. To stop the tool from the locked
position, pull the switch trigger fully, then release it.
Reversing switch action
Fig.6
This tool has a reversing switch to change the direction
of rotation. Move the reversing switch lever to the
position (A side) for clockwise rotation or to the
position (B side) for counterclockwise rotation.
CAUTION:
•
Always check the direction of rotation before operation.
•
Use the reversing switch only after the tool comes
to a complete stop. Changing the direction of
rotation before the tool stops may damage the tool.
Selecting the action mode
Fig.7
This tool has an action mode change lever. For rotation
with hammering, slide the action mode change lever to
the right (
symbol). For rotation only, slide the action
mode change lever to the left ( symbol).
CAUTION:
•
Always slide the action mode change lever all the
way to your desired mode position. If you operate
the tool with the lever positioned halfway between
the mode symbols, the tool may be damaged.
OPERATION
Fig.8
Always hold the tool only by the handle when
performing an operation. Do not touch the metal part.
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 toll and potentially serve injury.
When drilling in concrete, granite, tile, etc., slide the
action mode change lever to the position of
symbol
to use "rotation with hammering" action. Be sure to use
a tungsten-carbide tipped bit. 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.
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, slide
the action mode change 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.
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 carrying out any work on the
tool.
•
Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
To maintain product safety and reliability, repairs,
maintenance or adjustment should be carried out by a
Makita Authorized Service Center.
