Makita 6319D, Instruction Manual

Installing side grip (auxiliary handle) (Fig. 7)

Always use the side grip to ensure operating safety.
Install the side grip so that the steel band of the grip fits
on the tool barrel.
Then tighten the grip by turning clockwise at the desired
position. It may be swung 360° so as to be secured at
any position.

Installing or removing driver bit or drill bit

Turn the sleeve counterclockwise to open the chuck jaws.
Place the bit in the chuck as far as it will go. Turn the
sleeve clockwise to tighten the chuck. To remove the bit,
turn the sleeve counterclockwise. 

(Fig. 8)

When not using the driver bit, keep it in the bit holders.
Bits 45 mm long can be kept there. 

(Fig. 9)

Adjustable depth rod (accessory) (Fig. 10)

The adjustable depth rod is used to drill holes of uniform
depth. Loosen the clamp screw, set to desired position,
then tighten the clamp screw.

OPERATION

Screwdriving operation (Fig. 11)

First, slide the action mode change lever to the position
of 

 symbol and select the fastening torque.

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 switch 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.

NOTE:
• 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, slide the action mode change lever to the position
of 

m

 symbol.

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.

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 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.

• 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 attempting to perform
inspection or maintenance.

Replacing carbon brushes (Fig. 12 & 13)

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.
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 per-
formed by Makita Authorized or Factory Service Centres,
always using Makita replacement parts.
