Operation; Maintenance - Makita UM104D Instruction Manual

• Do not use force when inserting the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
Charging (Fig. 2)
Connect the charging plug to the charging connector,
then plug in the charger to the power receptacle. Insert
the battery cartridge so that the plus and minus terminals
on the battery cartridge are on the same sides as their
respective markings on the charging base. Insert the car-
tridge fully into the port so that it rests on the port floor.
Charging takes approx. 3 hours.
Battery type
7000
CAUTION:
• Overcharging more than 24 hours shortens the battery
service life. Always unplug the charger after completing
the charge.
• Use only the Makita charger to charge this machine.
Use of other type chargers may cause the battery to
burst, resulting in personal injury and damage.
• When you charge a new battery cartridge or a battery
cartridge which has not been used for a long period, it
may not accept a full charge. This is a normal condition
and does not indicate a problem. You can recharge the
battery cartridge fully after discharging it completely a
couple of times.
Switch action (Fig. 3)
CAUTION:
• Before inserting the battery cartridge into the tool,
always check to see that the switch trigger actuates
properly and returns to the "OFF" position when
released.
To prevent the trigger from being accidentally pulled, a
lock-off button is provided.
To start the tool, push in the lock-off button and pull the
trigger. Release the trigger to stop.
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 blade (Fig. 4 & 5)
Seriously damaged blades or blades that have been
sharpened numerous times should be replaced.
Replacement is accomplished by loosing the screws and
removing the blades.
When installing the new blades, rotate the gear so that its
ring is positioned in the blade guide hole. With
blades held in this position, replace the screws and
tighten them securely.
CAUTION:
• Do not remove the grease on the gears or gear housing
when replacing the blades.

OPERATION

WARNING:
• Keep hands away from blades.
Turn the tool on and hold it so that the foot of the tool rest
on the ground. Then gently move the tool forward into the
area to be cut. (Fig. 6)
When trimming around curb, fence or trees, move the
tool along them. Be careful for the blade not to contact
them. (Fig. 7)
CAUTION:
• Do not let the blades contact the grounds during opera-
tion. The blades will be dulled, causing poor perfor-
mance.
• When trimming twigs and foliage, do not attempt to trim
too much at a time. Proceed gently. Also, do not
attempt to cut thick branches. (Fig. 8)

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.
Blade maintenance
After operation, clean off the blades (both sides) with a
stiff brush. Then wipe the blades with a cloth and coat
them with light machine oil. (Fig. 9 & 10)
If the blades become dull or slightly damaged by contact
with foreign matter, they can usually be restored to their
original performance by sharpening with a file. (Fig. 11)
CAUTION:
• Dirt and corrosion cause excessive blade friction and
shorten the operating time per battery charge.
After use
• To clean off exterior of the tool, dampen a soft cloth in
soapy water and wipe gently. Never use thinner or ben-
zine.
• Do not store the tool in a place where volatile materials
are stored.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts.
