Insert the splinter guard in the space on the base, and
push it completely. (see Fig. 6)
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
CAUTIONS
While sawing, the base must be firmly in contact with
the material surface, and the blade must be held at a
right angle.
If the base becomes separated from the material, it
could cause the blade to break.
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)
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
Always use an appropriate cutting fluid (spindle oil,
soapy water, etc.) When a liquid cutting fluid is not
available, 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
The base can be swiveled to both sides by up to 45°
for angular cutting. (Fig. 14)
(1) Loosen 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)
NOTE:
Angular cutting can not be done when adopting chip
cover or dust collector.
CONCERNING CUTTING OF STAINLESS STEEL
PLATES
CAUTION
While sawing, the base must be firmly in contact with
the material surface, and the blade must be held at a right
angle. If the base becomes separated from the material,
it could cause the blade to break.
When cutting stainless steel plates, adjust the unit as
described below:
1. Adjust the speed......
Blade
Thickness of material
No. 96
0.5 – 1.5 mm
No. 95
1.5 – 2.5 mm
No. 97
1.5 – 2.5 mm
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.
HOUSING THE HEXAGONAL BAR WRENCH
It is possible to house the hexagonal bar wrench on the
base. (see Fig. 16)
