BLADE INSTALLATION

Set the blade orbit selector lever to position III.

Pull blade change knob upward as far as it will go and turn it three turns counter-clockwise (viewed from the top of the tool).

Insert the blade into blade plunger at a 90˚ angle to the cutting direction. With a slight upward pressure, turn the blade teeth forward (direction of cut) and guide the back of the blade into the groove in the center of blade roller guide. Pull gently down on the blade to seat the blade tabs in the plunger.

With the blade in the proper position, turn

knob clockwise until a noticable "Clic" noise is heard, indicating that the blade is locked in place. Depress knob to disengage and continue to turn knob until it is aligned with the curvature of the handle, and can be pressed back into its normal position. Press down on knob until it is flush with the handle, and the jigsaw is ready for use.

Removing the blade is essentially the reverse of the installation procedure, however, take note that once the blade change knob is loosened, gently push the blade upward to release the blade tabs from the plunger.

Operating Instructions

VARIABLE SPEED CONTROLLED

TRIGGER SWITCH

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 nameplate RPM by the pressure you apply to the trigger. Apply more pressure to increase the speed and release pressure to decrease speed.

"LOCK-ON" BUTTON

The "Lock-ON" button, located in the handle of your tool allows for continuous operation at maximum RPM without holding the trigger.

TO LOCK TRIGGER "ON": squeeze trigger, depress button and release trigger.

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

!WARNING If the “Lock-ON” button is continuously being depressed,

the trigger can not be released.

TRIGGER PRESET SPEED ADJUSTING DIAL This feature enables you to preset the trigger at desired speeds by rotating the dial on the trigger to a higher or lower setting. Regardless of the the pressure applied on trigger, the tool will not operate any faster that the maximum speed setting selected.

A-B	Low stroke
C-D	Medium stroke
E	High stroke

PLUNGER SPEED

The jigsaw cutting speed or stroke rate required depends on the material being cut, the type of blade 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 soft materials. Note that when the jigsaw is used at low speed settings for any length of time, the motor temperature will rise due to the slower speed 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 operating at high efficiency.

BLADE ORBIT

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.
