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 jig saw 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).

Controlled Trigger Switch
(Model JS470E only)
Your tool is equipped with a variable
speed trigger switch. The tool can be
turned "ON" or "OFF" by squeezing or
releasing the trigger. The speed can be
adjusted from the minimum to maximum
SPM as set on the variable speed dial by
the pressure you apply to the trigger.
Apply more pressure to increase the
speed and release pressure to decrease
speed.
Regardless of the pressure applied on
the trigger, the tool will not operate any
faster than maximum speed setting
selected on the variable speed dial.
