Drilling Operation - Makita HP0300 Betriebsanleitung

Installing hook
Optional accessory
CAUTION:
When installing the hook, always
secure it with the screw firmly. If not, the hook
may come off from the tool and result in the personal
injury.
► Fig.7: 1. Groove 2. Hook 3. Screw
The hook is convenient for temporarily hanging the tool.
This can be installed on either side of the tool. To install
the hook, insert it into a groove in the tool housing on
either side and then secure it with a screw. To remove,
loosen the screw and then take it out.
Installing driver bit holder
Optional accessory
► Fig.8: 1. Driver bit holder 2. Driver bit
Fit the driver bit holder into the protrusion at the tool foot
on either right or left side and secure it with a screw.
When not using the driver bit, keep it in the driver bit
holders. Driver bits 45 mm-long can be kept there.
OPERATION
CAUTION:
When the speed comes down
extremely, reduce the load or stop the tool to
avoid the tool damage.
► Fig.9: 1. Vent
Hold the tool firmly with one hand on the grip.
In the case of the twisting action, hold the grip firmly
with both hands.
NOTICE:
Do not cover vents, or it may cause over-
heating and damage to the tool.
Screwdriving operation
CAUTION:
Adjust the adjusting ring to the
proper torque level for your work.
CAUTION:
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
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 clutch cuts in.
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.

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

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
Optional accessory
► Fig.10: 1. Blow-out bulb
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.

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.
