Drilling Operation; Maintenance - Makita HP001G Betriebsanleitung

OPERATION
Hold the tool firmly with one hand on the grip and the
other hand on the handle to control the twisting action.
► Fig.14
NOTICE:
When the speed comes down extremely,
reduce the load or stop the tool to avoid the tool
damage.
NOTICE:
Do not cover vents, or it may cause over-
heating and damage to the tool.

Screwdriving operation
NOTICE:
Adjust the dial to the proper torque level
for your work.
NOTICE:
Make sure that the driver bit is inserted
straight in the screw head, or the screw and/or driver
bit may be damaged.
First, turn the action mode changing ring so that the
arrow on the tool body points to the
adjust the torque level.
Place the point of the driver bit in the screw head and
apply pressure to the tool. Start the tool slowly and then
increase the speed gradually. Release the switch trigger
as soon as the tool stops the rotation automatically and
the green light turns on for 5 seconds.
NOTE: When driving wood screw, pre-drill a pilot hole
2/3 the diameter of the screw. It makes driving easier
and prevents splitting of the workpiece.
NOTE: In a cold environment, the tool may stop at
lower torque level depending on circumstances.
Hammer drilling operation
CAUTION:
There is a tremendous and sud-
den 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
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.

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.
will not speed up the drilling. In fact, this excessive
pressure will only serve to damage the tip of your drill
marking, and bit, decrease the tool performance and shorten the
service life of the tool.
when the drill bit begins to break through the
