Operation; Maintenance - Makita DTM40 Instruction Manual

Lighting up the front lamp (Fig. 6)
WARNING:
• Never look into the light directly. Direct light causes
damage to your eyes.
Slide the slide switch toward the "I (ON)" position to light
up the front lamp. The lamp keeps on lighting while the
switch is the "I (ON)" position. The light automatically
goes out after pressing the rear of the slide switch, and
then sliding the slide switch toward the "O (OFF)" posi-
tion.
Overload protection
When the tool is overloaded and the tool temperature
reaches a certain level, the front lamp blinks and the tool
automatically stops. Remove a cause of overload to
restart.
Indication lamp (Fig. 7)
• When the remaining battery capacity gets low, the indi-
cation lamp blinks.
• When the remaining battery capacity gets much lower,
the tool stops during operation and the indication lamp
lights up about 10 seconds.
At this time, remove the battery cartridge from the tool
and charge it.
ASSEMBLY
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.
Installing or removing application tool (optional
accessory) (Fig. 8, 9 & 10)
WARNING:
• Do not install application tool upside down. Installing
application tool upside down may damage the tool and
cause serious personal injury.
• Install attachment tool in the correct direction according
to your work. Application tool can be installed at an
angle of every 30 degree.
Put an application tool (optional accessory) on the tool
flange so that the protrusions of the tool flange fit in the
holes in the application tool and secure the application
tool by tightening the bolt firmly with the hex wrench.
When using sanding application tool, mount the applica-
tion tool on the sanding pad so that it matches the sand-
ing pad direction.
The sanding pad has a hook and loop type fitting system
which allows easy and rapid fitting of a sanding paper.
As sanding papers have holes for dust extraction, mount
a sanding paper so that the holes in a sanding paper
match those in the sanding pad.
To remove a sanding paper, raise its end and peel it off.
Loosen and remove the application tool installation bolt
using a hex wrench and then take off the application tool.
When using application tools with a different type of
installation section, use a correct adapter (optional
accessory).
Hex wrench storage (Fig. 11)
When not in use, store the hex wrench as shown in the
figure to keep it from being lost.

OPERATION

WARNING:
• Before starting the tool and during operation, keep your
hand and face away from the application tool.
CAUTION:
• Do not apply excessive load to the tool which may
cause a motor lock and stop the tool.
Cutting, sawing and scraping (Fig. 12)
CAUTION:
• Do not move on the tool forcibly in the direction (eg.
towards either side) of tool application with no cutting
edge. It may damage the tool.
Put the application tool on the workpiece.
And then move the tool forward so that the application
tool movement does not slow down.
NOTE:
• Forcing or excessive pressure on the tool may reduce
efficiency.
• Before cutting operation, it is recommended to preset
the orbital stroke rate 4 – 6.
Sanding (Fig. 13)
CAUTION:
• Do not reuse a sanding paper used for sanding metal
to sand wood.
• Do not use a worn sanding paper or sanding paper
without grit.
Apply a sanding paper on the workpiece.
NOTE:
• Using a test material sample to try is recommendable
to determine a correct orbital stroke rate suitable for
your work.
• Use a sanding paper with the same grit until sanding
the whole workpiece is completed. Replacing a sand-
ing paper with different grit sanding paper may not get
a fine finish.
Dust extraction attachment (optional accessory)
(Fig. 14 & 15)
• Install dust nozzles and dust attachment.
• Install the nozzle band on the tool so that its protru-
sions fit in the holes in the tool to secure it.
• Put the felt ring and the sanding pad on the dust attach-
ment and then secure them with the application tool
installation bolt.
When you wish to perform cleaner operation, connect a
vacuum cleaner to your tool. Connect a hose of vacuum
cleaner to the dust extraction attachment (optional
accessory).

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.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
To maintain product SAFETY and RELIABILITY, repairs,
carbon brush inspection and replacement, any other
maintenance or adjustment should be performed by
Makita Authorized Service Centers, always using Makita
replacement parts.
