Additional Safety Rules; Maintenance - Makita 6407 Betriebsanleitung

20. Check damaged parts
Before further use of the tool, a guard or other part
that is damaged should be carefully checked to
determine that it will operate properly and perform
its intended function. Check for alignment of moving
parts, binding of moving parts, breakage of parts,
mounting, and any other conditions that may affect
its operation. A guard or other part that is damaged
should be properly repaired or replaced by an autho-
rized service center unless otherwise indicated else-
where in this instruction manual. Have defective
switches replaced by and authorized service center.
Do not use tool if switch does not turn it on and off.
21. Warning
The use of any other accessory or attachment other
than recommended in this operating instruction or
the catalog may present a risk of personal injury.
22. Have your tool repaired by an expert
This electric appliance is in accordance with the rel-
evant safety rules. Repairing of electric appliances
may be carried out only by experts otherwise it may
cause considerable danger for the user.

ADDITIONAL SAFETY RULES

1. Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
2. Hold the tool firmly.
3. Keep hands away from rotating parts.
4. When drilling into walls, floors or wherever
"live" electrical wires may be encountered, DO
NOT TOUCH ANY METAL PARTS OF THE TOOL!
Hold the tool by the insulated grasping surfaces
to prevent electric shock if you drill into a "live"
wire.
5. Do not leave the tool running. Operate the tool
only when hand-held.
6. Do not touch the drill bit or the workpiece imme-
diately after operation; they may be extremely
hot and could burn your skin.
SAVE THESE INSTRUCTIONS.
OPERATING INSTRUCTIONS
Installing or removing drill bit
Important:
Always be sure that the tool is switched off and
unplugged before installing or removing the bit.
For 6407 (Fig. 1)
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.
After using the chuck key, remember to return it to the
chuck key holder.
For 6408 (Fig. 2)
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.

Switch action (Fig. 3)
CAUTION:
Before plugging in the tool, always check to see that the
switch trigger actuates properly and returns to the "OFF"
position when released.
To start the tool, simply pull the trigger. Tool speed is
increased by increasing pressure on the trigger. Release
the trigger to stop. For continuous operation, pull the trig-
ger and then push in the lock button. To stop the tool from
the locked position, pull the trigger fully, then release it.
Reversing switch action (Fig. 4)
CAUTION:
• Always check the direction of rotation before drilling.
• Use the reversing switch lever only after the tool comes
to a complete stop. Changing the direction of rotation
before the tool stops may damage the tool.
This tool has a reversing switch to change the direction of
rotation. Move the reversing switch lever to the
tion for clockwise rotation or the
clockwise rotation.
Drilling operation
• 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 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 breakthrough. Hold the tool firmly and
exert care when the 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 tool may back out abruptly if you do not
hold it firmly.
• Always secure small workpieces in a vise or similar
hold-down device.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
