Maintenance; Operation - Makita 6016 Instruction Manual

ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing top grip (auxiliary handle)
(Fig. 2)
Screw the top grip on the tool securely.
Installing or removing drill bit (Fig. 3)
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, be sure to return to the original
position.
Adjusting depth of drilling (Fig. 4)
The depth gauge is convenient for drilling holes of uniform
depth.
Loosen the wing bolt and adjust the depth gauge to the
desired depth. After adjusting, tighten the wing bolt.

OPERATION

CAUTION:
• Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
"OFF" position when released.
Drilling operation (Fig. 5)
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.
• 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
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. 6)
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. (Fig. 7)
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.
