Functional Description - Makita DUR142L Instruction Manual

SAVE THESE INSTRUCTIONS.
CAUTION: Only use genuine Makita batteries.
Use of non-genuine Makita batteries, or batteries that
have been altered, may result in the battery bursting
causing fires, personal injury and damage. It will also void
the Makita warranty for the Makita tool and charger.
Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely
discharged.
Always stop tool operation and charge the battery
cartridge when you notice less tool power.
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room
temperature at 10°C - 40°C (50°F - 104°F). Let a hot
battery cartridge cool down before charging it.
4. Charge the battery cartridge if you do not use it for
a long period (more than six months).

FUNCTIONAL DESCRIPTION

WARNING:
• Always be sure that the tool is switched off and
battery cartridge is removed before adjusting or
checking the functions on the tool. Failure to switch
off and remove the battery cartridge may result in
serious personal injury from accidental start-up.
Installing or removing battery cartridge
(Fig. 5)
CAUTION:
• Always switch off the tool before installing or removing
of the battery cartridge.
• Hold the tool and the battery cartridge firmly when
installing or removing battery cartridge. Failure to
hold the tool and the battery cartridge firmly may cause
them to slip off your hands and result in damage to the
tool and battery cartridge and a personal injury.
To remove the battery cartridge, slide it from the tool while
sliding the button on the front of the cartridge.
To install the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip it
into place. Insert it all the way until it locks in place with a
little click. If you can see the red indicator on the upper
side of the button, it is not locked completely.
CAUTION:
• Always install the battery cartridge fully until the red
indicator cannot be seen. If not, it may accidentally fall
out of the tool, causing injury to you or someone
around you.
• Do not install the battery cartridge forcibly. If the
cartridge does not slide in easily, it is not being inserted
correctly.
Power switch action
WARNING:
• Before inserting the battery cartridge in the tool,
always check to see that the switch trigger

actuates properly and returns to the "OFF"
position when released. Do not pull the switch
trigger hard without turning the lock-off lever. This
can cause switch breakage. Operating a tool with a
switch that does not actuate properly can lead to loss
of control and serious personal injury. (Fig. 6)
Push the power button on the housing so that the tool is
powered on and power indicator lights. (Fig. 7)
To prevent the switch trigger from being accidentally
pulled, a lock-off lever is provided.
To start the tool, turn the lock-off lever and then pull the
switch trigger. Release the switch trigger to stop.
NOTE:
• After the power button is pushed and the tool is left one
minute without any operations, the tool is automatically
powered off.
Reversing switch for debris removal
WARNING:
• Always be sure that the tool is switched off and
battery cartridge is removed before removing
weeds or debris entangled in the tool that could not
be removed when operated in the reverse mode.
Failure to switch off and remove the battery cartridge
may result in serious personal injury from accidental
start-up. (Fig. 8)
This tool has a reversing switch which is only provided to
change the direction of rotation so that it can be used to
remove weeds and debris entangled in the tool. To
operate the tool normally the "A" side of the switch should
be depressed.
To remove weeds and debris that are jammed in the
rotating head the tool can be reversed by depressing the
"B" side of the switch. In the reverse position the tool will
only operate for a short period of time and automatically
shut off.
NOTICE:
• Always check the direction of rotation before operation.
• Use the reversing switch only after the tool comes to a
complete stop. Changing the direction of rotation
before the tool stops may damage it.
Speed adjusting dial (Fig. 9)
The tool speed can be infinitely adjusted from 3,500 min

to 6,000 min with the speed adjusting dial.
Turn the speed adjusting dial clockwise for higher speed,
and counterclockwise for lower speed.
Battery protection system (Lithium-ion
