• Do not jam the Disc or apply excessive
pressure. Do not attempt to make an
excessive depth of cut. Overstressing
the cut-off disc increases the loading
and susceptibility to twisting or
binding of the cut-off disc in the cut
and the possibility of kickback, cut-off
disc breakage and overheating of the
motor may occur.
• Do not start when disc is in the
workpiece. To do so causes the cut-off
disc binding or kickback. Let the
cut-off disc reach full speed and then
carefully cut the workpiece.
• During cutting operations, never
change the angle of the disc. Placing
side pressure on the cut-off disc (as in
grinding) will cause the disc to crack
and break, causing serious personal
injury.
CAUTION
• To prevent excessive temperature
increase of the tool surface, do not
operate the tool continuously using
two or more battery packs. The tool
needs cool-off time before switching
to another pack.
• Do not close up ventilation slots
on the sides of the body during
operation. Otherwise, the machine
function is adversely affected to
cause a failure.
• Do not strain the tool (motor). This
may cause damage to the unit.
• Use the tool in such a way as to
prevent the air from the ventilation
slots from blowing directly onto
your skin. Otherwise, you may get
burned.
Indicator lamp for On lock
start prevention function
The grinder will not start when the
battery pack is inserted with the switch
at the ON position (switch lever at ON).
The warning lamp will flash at this
time to indicate that the ‘On lock start
prevention function’ has operated.
[Fig.12]
Press the switch to the OFF position
(switch lever at OFF) and then press it
back to the ON position (switch lever at
ON) to start the grinder. [Fig.13]
Overheat warning lamp
[Fig.14]
Indicates operation has been halted due
to motor or battery overheating.
To protect the battery, be sure to note
the following when carrying out this
operation.
•
If the battery becomes hot, the
protection function will be activated
and the motor or battery will stop
operating. The overheat warning lamp
on the control panel illuminates or
flashes when this feature is active.
•
If the overheating protection feature
activates, allow the tool to cool
thoroughly (at least 30 minutes).
The tool is ready for use when the
overheat warning lamp goes out.
•
Avoid using the tool in a way that
causes the overheating protection
feature to activate repeatedly.
• If the tool is operated continuously
under high-load conditions or if it is
used in hot-temperature conditions
(such as during summer), the
overheating protection feature may
activate frequently.
•
If the tool is used in cold-temperature
conditions (such as during winter) or
if it is frequently stopped during use,
the overheating protection feature
may not activate.
•
The ambient temperature range
is between 0°C (32°F) and 40°C
(104°F). If the battery pack is used
when the battery temperature is
below 0°C (32°F), the tool may fail to
function properly.
•
When charging a cool battery pack
(below 0°C (32°F)) in a warm place,
leave the battery pack at the place
and wait for more than one hour to
warm up the battery to the level of the
ambient temperature.
