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.
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.
Chip Blower
Your jig saw is equipped with a two
position chip blower to help keep the
cutting line clear of chips.
Operating Instructions
Setting O
Hard materials such as
metals or thin sheet
metals. This setting can
be used with
blades, grit edge blades,
rasp work and down
cutting blades.
Setting I
Soft materials where
cleaner cutting
delicate scrolling work is
performed.
Setting II
Medium density
materials such as harder
woods or particle board.
Setting III
Soft materials such as
wood, plastics, etc. and
when fast cutting is
more important than a
clean cut.
By adjusting the chip blower lever the
force of the discharge air may be altered
as follows;
Footplate Angle Adjustment
The footplate may be tilted to allow
angle cuts up to 45° in either direction
(Fig. 8).
Note: before adjusting the footplate,
remove dust shroud and anti-splinter if
used.
Open the lock lever to unlock footplate.
Push and hold the footplate firmly
towards the back of tool as shown.
While holding the footplate backwards
knife
tilt footplate to desired angle on bevel
scale, then release pressure on
footplate so it engages into detent at
desired angle (Fig. 8).
