Overload protector and blade RPM speed control
The saw has a two-speed blade RPM speed control
(Fig A / 15). When cutting stainless or acid-proof
steel use the lower RPM setting l. When cutting
other materials use the faster RPM setting ll.
The saw also has an overload protector which
displays electric motor loading with three indicator
lights (Fig A / 5).
Explanation of indicator lights (FIGURE J)
GREEN
If green light is on, the motor temperature
and power output are normal.
You can continue using the tool.
YELLOW
If yellow light begins to flash, the motor is
hot and/or overloaded.
You should slow down the cutting
speed
(It is possible, that you are using a
worn-out blade)
RED
If the red light begins to flash, motor
power is automatically reduced to the
minimum to protect the motor. Cutting is
not possible.
Press the motor switch and let it run
freely (
UNDER NO LOAD)
until the
green light is on.
ATTENTION!
If the yellow light turns on when saw
is powered, it indicates that the motor control unit
has been damaged. You can finish the sawing, but
the saw should take out for service. If the motor
control unit is not repaired, the motor of the saw will
get damaged.
Improving possible misalignment of the cut
The cut is affected by many factors, e.g. the size of
the pipe, the material, the wall thickness, the quality
of the pipe's surface, the roundness, welded seams,
blade condition, feed rate, operator's experience.
For this reason, the saw may move to left or right
cussing unperfect cut (see Fig K).
