Operation; Maintenance; Optional Accessories - Maktec MT652 Instruction Manual

For Model MT653
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 opera-
tion, 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 (For Model MT653)
(Fig. 2)
This tool has a reversing switch to change the direction
of rotation. Move the reversing switch lever to the D
position (A side) for clockwise rotation or to the E posi-
tion (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.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing drill bit (Fig. 3)
CAUTION:
• Always be sure that the tool is switched off and
unplugged before installing or removing the bit.
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.

OPERATION

CAUTION:
• Always hold the tool only by the handle when perform-
ing an operation. Do not touch the metal part.
Drilling operation
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.
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 perfor-
mance 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.

• Always secure small workpieces in a vise or similar
hold-down device.

• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.

like. Discoloration, deformation or cracks may result.
