OPERATION
Fig.5
Drilling operation
Always use the top or back grip (auxiliary handle) and
firmly hold the tool by top or back grip and switch handle
during operations.
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 exceptions
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 performance and shorten the service life
of the tool.
•
There is a tremendous twisting 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.
•
Avoid drilling in material that you suspect contains
hidden nails or other things that may cause the bit
to bind or break.
MAINTENANCE
CAUTION:
•
Always be sure that the tool is switched off and
unplugged before attempting to perform inspection
or maintenance.
•
Never use gasoline, benzine, thinner, alcohol or
the like. Discoloration, deformation or cracks may
result.
Replacing carbon brushes
Fig.6
Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. Keep
the carbon brushes clean and free to slip in the holders.
Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes.
Fig.7
Use a screwdriver to remove the brush holder caps.
Take out the worn carbon brushes, insert the new ones
and secure the brush holder caps.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers,
always using Makita replacement parts.
