Constant Response Circuitry
The JS470EB's internal electronic
feedback system provides a "soft start",
which will reduce the stresses that
occur from a high torque start. With
both JS470EB and JS470E, 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.
By adjusting the chip blower lever the
force of the discharge air may be altered
as follows;
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.
Footplate Angle Adjustment
The footplate may be tilted to allow
angle cuts up to 45° in either direction
(Fig. 6).
To adjust footplate, remove dust shroud
if used, loosen the footplate screw with
5mm hex key and slide the footplate
slightly forward towards the back of tool,
then rotate to desired angle (Fig. 6).
The detent slots will hold the footplate
firmly at 0° or 45°, and there are
additional position marks for 15°, 22.5°
and 30° angles. Intermediate angles may
be set with a protractor (Fig. 6).
After positioning the footplate, securely
knife
tighten the footplate screw (Fig. 6).
