Maintenance - Makita 6216D Instruction Manual

Screwdriving operation (Fig. 9)
Place the point of the driver bit in the screw head and
apply pressure to the tool. Start the tool slowly and then
increase the speed gradually. Release the trigger as
soon as the clutch cuts in.
NOTE:
• Make sure that the driver bit is inserted straight in the
screw head, or the screw and/or bit may be damaged.
• When driving wood screws, predrill pilot holes to make
driving easier and to prevent splitting of the workpiece.
See the chart below.

• If the tool is operated continuously until the battery car-
tridge has discharged, allow the tool to rest for 15 min-
utes before proceeding with a fresh battery.
Drilling operation
First, turn the adjusting ring so that the pointer on the tool
m
body points to the marking. Then proceed as follows.
• 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
workpiece.
• 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. 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 perfor-
mance and shorten the service life of the tool.
• There is a tremendous 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.
• If the tool is operated continuously until the battery car-
tridge has discharged, allow the tool to rest for 15 min-
utes before proceeding with a fresh battery.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and the bat-
tery cartridge is removed before carrying out any work on
the tool.
Replacement of carbon brushes (Fig. 10 & 11)
Replace carbon brushes when they are worn down to the
