11.
Avoid accidental starting. Be sure switch is
off
before plugging
in.
Carrying tools with your finger on the switch or plugging in tools that
have the switch on invites accidents.
12. Remove adjusting keys or switches before turning the tool on. A
wrench or a key that is left attached to
a
rotating part of the tool may
result in personal injury.
13. Do not overreach. Keep proper footing and balance at all times.
Proper footing and balance enables better control of the tool in
unexpected situations.
14.
Use safety equipment. Always wear eye protection. Dust mask, nonskid safety shoes, hard hat, or hearing protection must be used for
appropriate conditions.
TOOL USE AND CARE
15.
Use clamps or other practical way
to
secure and support the work-
piece to a stable platform. Holding the work by hand or against your
body

17.
Do not use

if switch does not turn
it
on or off. Any tool that
cannot be controlled with the switch is dangerous and must be
repaired.
18. Disconnect the plug from the power source before making any
adjustments, changing accessories, or storing the tool. Such
preventive safety measures reduce the risk of starting the tool
accidentally.
19. Store idle tools out of reach of children and other untrained persons.
Tools
are dangerous in the hands of untrained users.
20. Maintain tools
with
care. Keep cutting tools sharp and clean. Properly
maintained tools, with sharp cutting edges are less likely to bind and
are easier to control.
21. Check for misalignment or binding of moving parts, breakage of parts,
and any other condition that may affect the tool’s operation. If
damaged, have the tool serviced before using. Many accidents are
caused by poorly maintained tools.
22. Use only accessories that are recommended by the manufacturer for
your model. Accessories that may be suitable for one tool, may
become
hazardous when used on another tool.
SERVICE
23.
Tool
service must be performed only by qualified repair personnel.
Service or maintenance performed by unqualified personnel could
result in a risk of injury.
24.
When servicing a tool, use only identical replacement parts. Follow
instructions
in
the Maintenance section of this manual. Use of
unauthorized parts or failure to follow Maintenance Instructions may
create a risk of electric shock or injury.

OPERATION
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 work-
piece.
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.

should be drilled dry.
N
CAUTIO
:
Pressing excessively on the tool will not speed up the drilling. In fact, this excessive
pressure will only serve damage the tip of your bit, decrease the tool performance
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 though the workpiece.
Always grip the small workpiece firmly with a vise or a holding means.
A stuck bit can be removed simply by setting the reversing switch to reverse rotation
in order to back out. However, the tool will pull away easily unless you hold it firmly
before starting the tool.
