Startup; Mitre Cutting; Use Of Hex Key On Base Plate Adjustment; Adjusting The Pendulum Stroke - jcb -20JS Instructions & User's Manual

Startup

Before switching on the jig saw the front
m
of the base plate must lie flat on the work
piece.
Always hold the jig saw firmly with both
m
hands. Make sure that the saw blade is not
in contact with the work piece before the jig
saw is turned on.
Allow the blade to come to a full stop
m
before removing it from the cut.
NOTE
Do not let the jig saw run in continuous
operation at the lowest speed. The motor
can overheat.

Mitre Cutting

For mitre sawing and flush-edge sawing the
m
base plate can be angled toward either side
in fixed steps (0°, 15°, 30° and 45°).
WARNING!
Only adjust the mitre angle when the jig saw
is switched off.
WARNING!
When adjusting the base plate, make sure
the forward and the rear locating teeth in the
jig saw body are aligned and fully engaged
in the corresponding slots in the base plate
before closing the locking lever.
Open the base plate locking lever (4).
m
Tilt the base plate (5) to the required
m
position.
Close the base plate locking lever to lock
m
the base plate into position.

Use of hex key on base plate
adjustment
NOTE
A hex key is provided in the package to use
for base plate tightening.
When adjusting the base plate, if required,
m
use a hex key to tighten the bolt underneath
the base plate.

Adjusting the Pendulum Stroke

Pendulum stroke is adjusted using the
m
stroke adjustment lever. The pendulum
stroke moves the saw blade in a horizontal,
pendulum motion.
At level 0, the jig saw works in linear stroke
m
and at levels 1-3 in pendulum stroke.
At level 3 the pendulum motion is at its
greatest.
To facilitate the removal of swarf from the
m
blade during cutting, the saw is pushed
backwards in the downward stroke.
This increases the cutting speed in the
longitudinal sections and less force is
therefore needed when cutting.
Using pendulum stroke increases the service
m
life of blades.
Correctly adjusting the pendulum stroke
m
improves the operation of the jig saw. The
blade is protected, the ejection of swarf
is improved and frictional heat is greatly
reduced.
NOTE
The pendulum stroke can be adjusted while
the jig saw is running.
