Maintenance; Drilling Operation; Optional Accessories - Makita DP4010 Instruction Manual

OPERATION
Holding the tool
Always use side grip (auxiliary handle) and fimly
hold the tool by side grip and switch handle during
operations.

Drilling operation

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 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 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.
• Avoid drilling in material that you suspect con-
tains hidden nails or other things that may cause
the bit to bind or break.
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.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspec-
tion or maintenance.
Cleaning vent holes
► 1. Vent holes
CAUTION:
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.

brush inspection and replacement, any other maintenance or
adjustment should be performed by Makita Authorized Service
