Overload protection
When the tool/battery is operated in a manner that
causes it to draw an abnormally high current, the tool
stops automatically. In this situation, turn the tool off
and stop the application that caused the tool to become
overloaded. Then turn the tool on to restart.
Overheat protection
When the tool/battery is overheated, the tool stops
automatically. In this situation, let the tool/battery cool
before turning the tool on again.
Overdischarge protection
When the battery capacity is not enough, the tool stops
automatically. In this case, remove the battery from the
tool and charge the battery.
Protection lock function
When the protection system works repeatedly, the tool is locked.
In this situation, the tool does not start even if turning the tool
off and on. To release the protection lock, remove the battery,
set it to the battery charger and wait until the charging finishes.
Switch action
CAUTION:
Before installing the battery car-
tridge into the tool, always check to see that the
tool is switched off.
► Fig.2: 1. Slide switch
To start the tool, slide the slide switch toward the "I
(ON)" position.
To stop the tool, slide the slide switch toward the "O
(OFF)" position.
Adjusting the orbital stroke rate
► Fig.3: 1. Dial
The orbital stroke rate is adjustable. To change the orbital
stroke rate, turn the dial between 1 and 6. The higher the
number is, the higher the orbital stroke rate is. Preset the
dial to the number suitable for your workpiece.
NOTE: The dial cannot be turned directly from 1 to 6
or from 6 to 1. Forcing the dial may damage the tool.
When changing the dial direction, always turn the dial
moving it through each intermediate number.
Lighting up the front lamp
CAUTION:
Do not look in the light or see the
source of light directly.
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 front lamp goes out 10 seconds after sliding switch
toward the "O (OFF)" position.
► Fig.4: 1. Front lamp
NOTE: When the overheat protection or the protec-
tion lock function is working, the front lamp blinks for
about 1 minutes. Refer the section for the tool / bat-
tery protection system.
Electronic function
The tool is equipped with the electronic functions for
easy operation.
Constant speed control
The speed control function provides the constant orbital
stroke rate regardless of load conditions.
Soft start feature
Soft start feature reduces starting reaction.
Accidental re-start preventive
function
When installing the battery cartridge while the slide
switch in the "I (ON)" position, the tool does not start.
To start the tool, first slide the slide switch toward the
"O (OFF)" position and then slide it toward the "I (ON)"
position.
ASSEMBLY
Installing or removing battery
cartridge
CAUTION:
Always switch off the tool before
installing or removing of the battery cartridge.
CAUTION:
Hold the tool and the battery car-
tridge 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.
► Fig.5: 1. Red indicator 2. Button 3. Battery cartridge
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 as
shown in the figure, 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.
CAUTION:
Do not install the battery cartridge
forcibly. If the cartridge does not slide in easily, it is
not being inserted correctly.
CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before carrying out any work on the tool.
