measures reduce the risk of starting the tool accidentally.
Plunger Speed
The jigsaw cutting speed or stroke rate
required depends on the material being
cut, the type of blade being used, and
the feed rate preferred by the operator.
The best speed for a particular
application is largely determined by
experience though as a general rule,
slower speeds are for denser materials
and faster speeds for softer materials.
Note: that when the jigsaw is used at
low speed settings for an extended
length of time, the motor temperature
will rise due to slower speeds of the
internal cooling fan. In such cases, it is
necessary to occasionally run the tool at
full speed for a few minutes to keep the
motor running at high efficiency.
Variable Speed Dial
Your Jigsaw is equipped with a variable
speed dial. The blade stroke rate may be
adjusted during cutting operation by
presetting the dial on or between any
one of the six numbers (Fig. 5).
