Operating Instructions

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.

TRIGGER SWITCH WITH "LOCK-ON" BUTTON

(Model 1590EVS only)

Your jigsaw can be turned "ON" or "OFF" by squeezing or releasing the trigger. Your jigsaw is also equipped with a "Lock-ON" button located just above the trigger that allows continuous operation without holding the trigger (Fig. 1).

TO LOCK SWITCH ON: Squeeze trigger fully, depress button and release trigger.

TO UNLOCK THE SWITCH: Squeeze trigger and release it without depressing the "Lock- ON" button.

!WARNING If the "Lock-ON" button is continuously being de-

pressed, the trigger cannot be released.

SLIDE ON-OFF SWITCH (Model 1591EVS only)

The tool is switched “ON” by the switch button located at the side of the motor housing. The switch locks in the “ON” position, a convenience for continuous operation (Fig. 1).

TO TURN THE TOOL “ON” slide the switch button forward.

TO UNLOCK THE SWITCH, slide the switch button backward.

CONSTANT RESPONSE CIRCUITRY The internal electronic feedback system provides a "soft start", which will reduce the stresses that occur from a high torque start. The system also maintains the selected speed under load for maximum 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.

Setting SPM rating (strokes per minute)

1500

2500-800

3500-1400

4500-1900

5500-2400

6500-2800

BLADE ORBIT SELECTOR LEVER

Maximum cutting efficiency can be obtained by adjusting the blade orbit selector lever to suit the material being cut.

The following chart will help you determine which setting to use for your application. This chart is intended as a guideline only, and test cuts in scrap material should be performed first to determine the best setting.

Setting O

Hard materials such as metals or thin sheet metals. This setting can be used with knife blades, grit edge blades, rasp work and down cutting blades.

Setting 1

Soft materials where cleaner cutting or delicate scrolling work is performed.

Setting 2

Medium density materials such as harder woods or particle board.

Setting 3

Soft materials such as wood, plastics, etc. and when fast cutting is more important than a clean cut.
