Power supply
The machine should be connected only to a power
supply of the same voltage as indicated on the
nameplate, and can only be operated on single-phase
AC supply. They are double-insulated in accordance
with European Standard and can, therefore, also be
used from sockets without earth wire.
Safety hints
For your own safety, please refer to enclosed Safety
instructions.
These symbols mean:
Read instruction manual.
DOUBLE INSULATION
ADDITIONAL SAFETY RULES
1. Avoid cutting nails. Inspect for and remove all
nails from the workpiece before operation.
2. Do not cut oversize workpiece.
3. Check for the proper clearance beyond the
workpiece before cutting so that the blade will
not strike the floor, workbench, etc.
4. Hold the machine firmly.
5. Make sure the blade is not contacting the
workpiece before the switch is turned on.
6. Keep hands away from moving parts.
7. When cutting through walls, floors or wher-
ever ‘‘live’’ electrical wires may be encoun-
tered, DO NOT TOUCH ANY METAL PARTS OF
THE MACHINE! Hold the machine by the insu-
lated grasping surfaces to prevent electric
shock if you cut through a ‘‘live’’ wire.
8. Do not leave the machine running. Operate the
machine only when hand-held.
9. Always switch off and wait for the blade to
come to a complete stop before removing the
blade from the workpiece.
10. Do not touch the blade or the workpiece imme-
diately after operation; they may be extremely
hot and could burn your skin.
SAVE THESE INSTRUCTIONS.
OPERATING INSTRUCTIONS
Installing saw blade (Fig. 1)
Important:
Always be sure that the machine is switched off and
unplugged before installing or removing the blade.
First, use the hex wrench to loosen the bolt. With the
blade teeth facing upward or downward, insert the
blade until the hole in the blade shank is just over the
protrusion on the slider. Then tighten the bolt to
secure the blade.
Adjusting shoe (Fig. 2)
Loosen the two bolts holding the shoe. Then slide the
shoe back or forth to the desired position and tighten
the two bolts securely. When the blade loses its
cutting effectiveness in one place, reposition the shoe
to obtain better cutting in another.
Speed change (For JR3000 only) (Fig. 3)
CAUTION:
Use the speed change switch only after the machine
comes to a complete stop.
To change the machine speed, move the speed
change switch to the ‘‘L’’ position for low speed or the
‘‘H’’ position for high speed.
High speed: ordinary wood, plys or plastics
Low speed: metals (steel pipe, sheet metal, stainless
or copper)
Switch action (For JR3000) (Fig. 4)
CAUTION:
Before plugging the machine, always check to see
that the switch trigger actuates properly and returns to
the ‘‘OFF’’ position when released.
