9. Chip cover
Chip cover prevents chips from flying off and
improves the efficiency of dust collector.
Insert the chip cover between the base and lever,
and push with a slight pressure until it catches in
place. (Fig. 7)
When removing chip cover, hold both sides of knob
and slightly open until it can be removed from the
Jig Saw. (Fig. 8)
NOTE:
There is a possibility that chip cover is frosted when
cutting the metal.
10. Sub base
Using the sub base (made from steel) will reduce
abrasion of aluminium base especially in cutting
metals.
Using the sub base (made from resin) will reduce
scratching of cut surface. Attach the sub base to
the bottom surface of base by attached 4 screws.
CUTTING
CAUTION:
In order to prevent blade dislodging, damage or
excessive wear on the Plunger, please make sure
to have surface of the base plate attached to the
work piece while sawing.
1. Rectilinear cutting
When cutting on a straight line, first draw a marking
gauge line and advance the saw along that line.
Using the guide (sold separately) will make it
possible to cut accurately on a straight line.
(1) Loosen the base bolt hexagonal bar wrench attached
on base. (Fig. 9)
(2) Move the base fully forward (Fig. 10), and tighten
the base bolt again.
(3) Attach the guide by passing it through the
attachment hole on the base and tighten the M5
bolt. (Fig. 11)
(4) set the orbital position to “0”.
NOTE:
To ensure accurate cutting when using the Guide
(Fig. 11) always set the orbital position to “0”
2. Sawing curved lines
When sawing a small circular arc, reduce the feeding
speed of the machine. If the machine is fed too fast,
it could cause the blade to break.
3. Cutting a circle or a circular arc
The guide also will be helpful for circular cutting.
After attaching the guide by same way noted as
above, drive the nail or screw into the material
through the hole on the guide, then use it for a
axis when cutting. (Fig. 12)
NOTE:
Circular cutting must be done with the blade
approximately vertical to the bottom surface of the
base.
4. Cutting metallic materials
(1) Adjust the speed Dial between scales “3” and “4”.
(2) Set the orbital position to “0” or “1”.
(3) Always use an appropriate cutting fluid (spindle oil.
soapy water, etc.). When a liquid cutting fluid is not
avaiable, apply grease to the back surface of the
material to be cut.
5. Pocket cutting
(1) In lumber
Aligning the blade direction with the grain of the
wood, cut step by step until a window hole is cut
in the center of the lumber. (Fig. 13)
(2) In other materials
When cutting a window hole in materials other than
lumber, initially bore a hole with a drill or similar
tool from which to start cutting.
6. Angular cutting
base can be swiveled to both sides by up to 45°
for angular cutting. (Fig. 14)
(1) the base bolt by hexagonal bar wrench attached on
base and move the base fully forward. (Fig. 9, 10)
(2) Align the scale (from 0 degrees to 45 degrees by
15-degree increments) of the semi-circular part of
the base with the [
] mark on the gear cover.
(Fig. 15)
(3) Tighten the M5 bolt again. (Fig. 9)
(4) Set the orbital position to “0”.
NOTE:
Angular cutting can not be done when adopting
chip cover or dust collector.
CONCERNING CUTTING OF STAINLESS
STEEL PLATES
CAUTION:
In order to prevent blade dislodging, damage or
excessive wear on the Plunger, please make sure to
have surface of the base plate attached to the work
piece while sawing.
When cutting stainless steel plates, adjust the unit as
described below:
1. Adjust the speed
NOTE:
Dial scale reading is for reference only. The higher
the speed is, the quicker the material is cut. But
the service life of the blade will be reduced in this
case. When the speed is too low, cutting will take
longer, although the service life will be prolonged.
Make adjustments as desired.
2. Set the orbital position to “0”
NOTE:
When cutting use cutting fluid (oil base cutting
fluid) to prolong the blade’s service life.
SELECTION OF BLADES
Accessory blades
To ensure maximum operating efficiency and results,
it is very important to select the appropriate blade
best suited to the type and thickness of the material
to be cut. Three types of blades are provided as
standard accessories. The blade number is engraved
in the vicinity of the mounting portion of each
blade. Select appropriate blades by referring to
Table 1.
