battery cartridge is removed before adjusting or
checking function on the tool.
Installing or removing battery cartridge
Fig.1
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.
Switch action
CAUTION:
Before installing 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 by pushing the rear of the slide switch. 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.
Accidental re-start preventive function
Even if the battery cartridge is installed on the tool with 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.
Electronic torque control function
The tool electronically detects situations where the
wheel or accessory may be at risk to be bound. In the
situation, the tool is automatically shut off to prevent
further rotation of the spindle (it does not prevent
kickback).
To restart the tool, switch off the tool first, remove the
cause of sudden drop in the rotation speed, and then
turn the tool on.
