Attaching the Blade
To prevent personal injury,
always disconnect plug from
power source before assembling parts, making
adjustments, or changing blades.
1. Insert the saw blade (teeth in cutting
direction) until it latches in the plunger
(Fig. 3).
When inserting the saw blade, the back of
the blade must rest in the groove of the
guide roller (Fig. 4).
2. To remove blade, lift tool-less blade change
cover up with index finger and thumb and
remove blade.
For use with both T or U shank jigsaw blades.

TRIGGER SWITCH
(Models 4480 & 4540 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
nameplate SPM by the pressure you apply to the
trigger. Apply more pressure to increase the
speed and release pressure to decrease speed
(Fig. 1).
"LOCK-ON" BUTTON
The "Lock-ON" button, located in the handle of
your tool allows for continuous operation at
maximum SPM without holding the trigger
(Fig. 1).
TO LOCK TRIGGER "ON": squeeze trigger,
depress button and release trigger.

Your tool 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.

ELECTRONIC FEEDBACK CIRCUITRY (EFC)
(Models 4485 & 4580 only)
The internal electronic feedback system
helps to keep the no load speed virtually
constant between no-load and load
conditions.
PLUNGER SPEED
The stroke rate may be adjusted as described
earlier under “Variable Speed Dial”. The best
results for a particular application are
determined by experience, though as a general
rule, slower speeds are for denser materials
and faster speeds are for soft materials.
