Makita HP2032 Betriebsanleitung Seite 6

For HP2033 (Fig. 3)
Hold the ring and turn the sleeve counterclockwise to
open the chuck jaws. Place the bit in the chuck as far
as it will go. Hold the ring firmly and turn the sleeve
clockwise until the chuck is tightened with a little click.
After the click, always tighten the chuck additionally to
prevent accidental loosening during operation.
To remove the bit, hold the ring and turn the sleeve
counterclockwise.
Depth gauge (Fig. 4)
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 gear
housing.
Switch action (Fig. 5)
CAUTION:
Before plugging in the machine, always check to see
that the switch trigger actuates properly and returns to
the ''OFF'' position when released.
For HP2032 and HP2033
To start the machine, simply pull the trigger. Machine
speed is increased by increasing pressure on the
trigger. Release the trigger to stop. For continuous
operation, pull the trigger and then push in the lock
button. To stop the machine from the locked position,
pull the trigger fully, then release it.
For HP2034
To start the machine, simply pull the trigger. Release
the trigger to stop. For continuous operation, pull the
trigger and then push in the lock button. To stop the
machine from the locked position, pull the trigger fully,
then release it.
Reversing switch action (Fig. 6)
For HP2032 and HP2033
CAUTION:
• Always check the direction of rotation before opera-
tion.
• Use the reversing switch only after the machine
comes to a complete stop. Changing the direction of
rotation before the machine stops may damage the
machine.
This machine has a reversing switch to change the
direction of rotation. Move the reversing switch lever
to the position
the position for counterclockwise rotation.
Speed change knob (Fig. 7)
Two rpm ranges can be preselected with the speed
change knob. Turn the speed change knob to the
position 1 or position 2.
Position 1:0 – 850 rpm (Fig. 7-1)
Position 2:0 – 2,900 rpm. (Fig. 7-2)
If it is hard to turn the knob, first turn the chuck slightly
in either direction and then turn the knob again.

Selecting action mode (Fig. 8)
This machine has an action mode change knob.
For rotation with hammering, turn the action mode
change knob to the posision of
For rotation only, turn the action mode change knob to
the position of
CAUTION:
Always turn the action mode change knob all the way
to your desired mode position. If you operate the
machine with the kob positioned half-way between
the mode symbols, the machine may be damaged.
Operation
1) Hammer drilling operation
When drilling in concrete, granite, tile, etc., turn
the action mode change knob to the position of
symbol to use ''rotation with hammering''
action. Be sure to use a tungsten-cabide tipped
bit. Do not apply more pressure when the hole
becomes clogged with chips or particles. Instead,
run the machine 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. (Fig. 9)
2) Drillng operation
When drilling in wood, metal or plastic materials,
turn the action mode change knob to the position
of symbol to use ''rotation only'' action.
• Drilling in wood
When drilling in wood, 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 centerpunch
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 machine will not
speed up the drilling. In fact, this excessive
pressure will only serve to damage the tip of
your bit, decrease the machine performance
and shorten the service life of the machine.
• There is a tremendous twisting force exerted on
the machine/bit at the time of hole breakthrough.
Hold the machine firmly and exert care when the
or
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 machine may back out
abruptly if you do not hold it firmly.
• Always secure small workpieces in a vise or
similar hold-down device.
