Drilling Operation; Drilling In Wood; Drilling In Metal - Makita DA001G Instruction Manual

When drilling a large hole with a self-feed bit, etc., the
side grip (auxiliary handle) should be used as a brace to
maintain safe control of the tool.
When drilling action is forward (clockwise), the tool
should be braced to prevent a counterclockwise reac-
tion if the bit should bind.

When reversing, brace the tool to prevent a clockwise
reaction. If the drill bit must be removed from a partially
drilled hole, be sure the tool is properly braced before
reversing.

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 drill bit into
the workpiece.

Drilling in metal

To prevent the drill 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
drill 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 drill bit, decrease
the tool performance and shorten the service life of the tool.
Hold the tool firmly and exert care
CAUTION:
when the drill bit begins to break through the
workpiece. There is a tremendous force exerted on
the tool/drill bit at the time of hole break through.
CAUTION:
A stuck drill 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.
CAUTION:
Always secure workpieces in a
vise or similar hold-down device.
CAUTION:
Avoid drilling in material that you
suspect contains hidden nails or other things that
may cause the drill bit to bind or break.
CAUTION:
If the tool is operated continuously until
the battery cartridge has discharged, allow the tool to rest
for 15 minutes before proceeding with a fresh battery.
Lanyard (tether strap) connection
Safety warnings specific for use at height
Read all safety warnings and instructions. Failure to follow
the warnings and instructions may result in serious injury.
1. Always keep the tool tethered when working "at
height". Maximum lanyard length is 2 m (6.5 ft).
The maximum permissible fall height for lan-
yard (tether strap) must not exceed 2 m (6.5 ft).
2. Use only with lanyards appropriate for this tool
type and rated for at least 8.0 kg (17.6 lbs).
3. Do not anchor the tool lanyard to anything on
your body or on movable components. Anchor
the tool lanyard to a rigid structure that can
withstand the forces of a dropped tool.
4. Make sure the lanyard is properly secured at
each end prior to use.
5. Inspect the tool and lanyard before each use for dam-
age and proper function (including fabric and stitching).
Do not use if damaged or not functioning properly.
6. Do not wrap lanyards around or allow them to
come in contact with sharp or rough edges.
7. Fasten the other end of the lanyard outside the
working area so that a falling tool is held securely.
8. Attach the lanyard so that the tool will move away
from the operator if it falls. Dropped tools will swing on
the lanyard, which could cause injury or loss of balance.
9. Do not use near moving parts or running
machinery. Failure to do so may result in a crush
or entanglement hazard.
10. Do not carry the tool by the attachment device
or the lanyard.
11. Only transfer the tool between your hands
while you are properly balanced.
12. Do not attach lanyards to the tool in a way that keeps
guards, switches or lock-offs from operating properly.
13. Avoid getting tangled in the lanyard.
14. Keep lanyard away from the cutting area of the tool.
15. Use multi-action and screw gate type carabineers.
Do not use single action spring clip carabineers.
