Switch action (Fig. 7, 8 & 9)
CAUTION:
Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
"OFF" position when released.
For tools with lock button

When the portion with
cent to the pointer, full speed can be obtained
Continuous operation can be performed only when
the knob is set to the full speed position. To perform
continuous operation, pull the trigger fully and then
push the lock button up. To stop the tool from the
locked position, pull the trigger fully, then release it.

Operation (Fig. 10)
Press the shoe firmly against the workpiece. Do not
allow the tool to bounce. Bring the blade into light
contact with the workpiece. First, make a pilot
groove, using a slower speed. Then use a faster
speed to continue cutting.
CAUTION:
• Always use a suitable coolant (cutting oil) when cut-
ting metal. Failure to do so will cause premature
blade wear.
• Always wear gloves to protect your hands from hot
flying chips when cutting metal.
• Always press the shoe firmly against the workpiece
during operation. If the shoe is held away from the
workpiece during operation, strong vibration and/or
twisting will be produced, causing the blade to snap
dangerously.
• Be sure to always wear suitable eye protection
which conforms with current national standards.
