CUTTING
CAUTION
䡬 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.
䡬 At low speed do not cut a wood with a thickness of
more than 10 mm or metal with a thickness of more
than 1 mm.
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. 15)
(2) Move the base fully forward (Fig. 16), 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. 17)
(4) Set the orbital position to “0”.
NOTE:
To ensure accurate cutting when using the Guide (Fig.
17), 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 an axis when cutting.
(Fig. 18)
NOTE:
Circular cutting must be done with the blade
approximately vertical to the bottom surface of the
base.
4. Cutting metallic materials
(1) Set the orbital position to “0” or “I”.
(2) Cut the material at medium speed.
(3) 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. 19)
(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. 20)
(1) Loosen the base bolt by hexagonal bar wrench
attached on base and move the base fully forward.
(Fig. 15, 16)
(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. 21)
(3) Tighten the M5 bolt again. (Fig. 15)
(4) Set the orbital position to “0”.
NOTE:
Angular cutting can not be done when adopting chip
cover or dust collector.
CONNECTING WITH CLEANER
By connecting with cleaner (sold separately) through dust
collector (sold separately) and adapter (sold separately),
most of dust can be collected.
(1) Remove the hexagonal bar wrench from the base.
(2) Move the base fully forward. (Fig. 15, 16)
(3) Attach the chip cover.
(4) Connect the dust collector with adapter. (Fig. 22)
(5) Connect the adapter with the nose of cleaner. (Fig.
22)
(6) Insert dust collector into the rear hole of the base until
the hook catches in the notch. (Fig. 23)
(7) Press the hook to remove the dust collector.
NOTE:
Wear the dust mask additionally, if available.
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:
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:
䡬 When cutting use cutting fluid (oil base cutting fluid)
to prolong the blade’s service life.
SELECTION OF BLADES
䡬 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 5.
HOUSING THE HEXAGONAL BAR WRENCH
It is possible to house the hexagonal bar wrench on the
base. (See Fig. 24)
