NOTE:
•
Depending on the conditions of use and the
ambient temperature, the indication may differ
slightly from the actual capacity.
Switch action
Fig.4
CAUTION:
•
Before inserting the battery cartridge into the tool,
always check to see that the slide switch actuates
properly and returns to the "OFF" position when
the rear of the slide switch is depressed.
•
Switch can be locked in "ON" position for ease of
operator comfort during extended use. Apply
caution when locking tool in "ON" position and
maintain firm grasp on tool.
To start the tool, slide the slide switch toward the "I
(ON)" position. For continuous operation, press the front
of the slide switch to lock it.
To stop the tool, press the rear of the slide switch, then
slide it toward the "O (OFF)" position.
Indication lamp with multi function
Fig.5
Indication lamps are located in two positions.
When the battery cartridge is inserted on the tool with
the slide switch positioned in the "O (OFF)" position, the
indication lamp flickers quickly for approximately one
second. If it does not flicker so, the battery cartridge or
indication lamp has broken.
−
Overload protection
−
When the tool is overloaded, the indication
lamp lights up. When the load on the tool is
reduced, the lamp goes out.
−
If the tool continues to be overloaded and the
indication lamp continues to light up for
approximately two seconds, the tool stops.
This prevents the motor and its related parts
from being damaged.
−
In this case, to start the tool again, move the
slide switch to the "O (OFF)" position once
and then to the "I (ON)" position.
−
Battery cartridge replacing signal
−
When the remaining battery capacity gets small,
the indicator lamp lights up during operation
earlier than enough capacity battery use.
−
Accidental re-start preventive function
−
Even if the battery cartridge is inserted on
the tool with the slide switch in the "I (ON)"
position, the tool does not start. At this time,
the lamp flickers slowly and this shows that
the accidental re-start preventive function is
at work.
−
To start the tool, first slide the slide switch
toward the "O (OFF)" position and then slide
it toward the "I (ON)" position.
ASSEMBLY
CAUTION:
•
Always be sure that the tool is switched off and the
battery cartridge is removed before carrying out
any work on the tool.
Installing or removing wheel point
Fig.6
Loosen the collet nut and insert the wheel point into the
collet nut. Use one wrench to hold the spindle and the
other one to tighten the collet nut securely.
The wheel point should not be mounted more than 10
mm from the collet nut. Exceeding this distance could
cause vibration or a broken shaft.
Fig.7
To remove the wheel point, follow the installation
procedure in reverse.
CAUTION:
•
Use the correct size collet cone for the wheel point
which you intend to use.
