Instruction & User Manual
Stroke Rate Selection Dial
m
The maximum stroke rate of the blade can
be adjusted using the dial, from 1 (slow) to
6 (fast).
m
The required stroke rate of the saw blade
is dependant on the material and the saw
blade used and should be determined by
practical tests. The following table can be
used as a guide to help with initial settings.
Material
Stroke Rate
Wood
5 - 6
Soft Steel
3 - 6
Stainless Steel
3 - 4
Aluminium
3 - 6
Plastic
1 - 4
Do not let the jig saw run continuously at the
lowest speed. The motor can overheat.
NOTE
Mitre Cutting
m
For mitre sawing and flush-edge sawing the
base plate can be angled toward either side
in fixed steps (0°, 15°, 30° and 45°).
Only set the mitre angle when the tool is
stopped and the blade has stopped moving.
Otherwise the tool can be damaged.
WARNING!
m
Open the base plate locking lever.
m
Tilt the saw shoe to the required position.
m
Close the base plate locking lever to lock
the base plate into position.
Adjusting the Pendulum Stroke
m
Pendulum stroke is adjusted using the
stroke adjustment lever. The pendulum
stroke moves the saw blade in a horizontal,
pendulum motion.
m
At level 0, the jig saw works in linear stroke
and at levels 1-3 in pendulum stroke.
At level 3 the pendulum motion is at its
greatest.
m
To facilitate the removal of swarf from the
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.
m
Using pendulum stroke increases the service
life of blades.
m
Correctly adjusting the pendulum stroke
improves the operation of the jig saw. The
blade is protected, the ejection of swarf
is improved and frictional heat is greatly
reduced.
The pendulum stroke can be adjusted while
the jig saw is running.
NOTE
Lever Position: 0 - Linear Stroke
