VARIABLE SPEED CONTROL AND ON/Off SWITCH
CAUTION
!
for your own safety, always push the switch
"Off" when the scroll saw is not in use. Also, in the
case of power failure (all of your lights go out) push the
knob "OFF". Remove the plug from the power source
outlet to avoid accidental starting.
ON/Off SWITCH (fIG. P)
. To turn power ON, press on/off switch () to "ON"
position.
. To turn power Off, press on/off switch () to "Off"
position.
VARIABLE SPEED CONTROL KNOB (fIG. P)
The variable speed control allows greater versatility to
cut a variety of materials such as wood, plastics, non-
ferrous metals, etc. Depending on the hardness and
thickness of material, the speed should be reduced to
allow the blade teeth to remove cut material from the
kerf.
. Your saw is equipped with a variable speed control
knob (). The blade stroke rate may be adjusted by
simply rotating the variable speed control knob ().
. Turn the speed control knob clockwise to increase up
to ,500 strokes per minute (SPM). Turn the speed
control knob counterclockwise to reduce down to 500
strokes per minute (SPM).
WORK LIGHT (fIG. P)
1. To turn work light on, press the rocker switch (3) to
"ON" position.
2. To turn work light off, press the rocker switch (3) to
"Off" position.
