Drilling Operation - Makita HP1630 Betriebsanleitung

To stop the tool from the locked position, pull the switch
trigger fully, then release it.
Reversing switch action (Fig. 2)
This tool has a reversing switch to change the direction of
rotation. Move the reversing switch to the
side) for clockwise rotation or the
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.
• If the switch trigger can not be depressed, check to see
that the reversing switch is fully set to position
E
side) or (B side).
Selecting the action mode (Fig. 3)
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 (
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.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing side grip (auxiliary handle) (Fig. 4)
Always use the side grip to ensure operating safety.
Install the side grip on tool barrel.
Then tighten the grip by turning clockwise securely at the
desired position. It may be swung 360° so as to be
secured at any position.
NOTE:
• The side grip cannot swing 360° when the depth gauge
is installed.
Installing or removing drill bit
For Model HP1630 (Fig. 5)
To install the bit, place it in the chuck as far as it will go.
Tighten the chuck by hand. Place the chuck key in each
of the three holes and tighten clockwise. Be sure to
tighten all three chuck holes evenly.
To remove the bit, turn the chuck key counterclockwise in
just one hole, then loosen the chuck by hand.
For Model HP1631 (Fig. 6)
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 clock-
wise to tighten the chuck.
To remove the bit, hold the ring and turn the sleeve coun-
terclockwise.
Depth gauge (Fig. 7)
The depth gauge is convenient for drilling holes of uni-
form 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
CAUTION:
• Always use the side grip (auxiliary handle) and firmly
hold the tool by both side grip and switch handle during
operations.
Hammer drilling operation (Fig. 8)
CAUTION:
• There is a tremendous and sudden twisting force
exerted on the tool/bit at the time of hole break-
(A
through, when the hole becomes clogged with chips
and particles, or when striking reinforcing rods embed-
ded 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 pres-
sure gives best results. Keep the tool in position and pre-
vent 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
bol 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 excep-
tions are iron and brass which should be drilled dry.
