Ground
This metal saw is single insulated tool, so the
ground
system is provided to protect you
from being shocked. The appropriate
ground
system is set up as soon as this machine is
plugged into the proper power supply
system. Therefore, the standard power
supply system shall be provided for this
machine in order to protect you from the risk
of shock.
DANGER: To avoid electric shock
1. Do not change the power cord and
plug to another specification not
provided by the manufacturer.
2. Do not use in rain or where floor is
wet. This tool is intended for indoor
residential use only.
Motor Safety Protection
CAUTION:
To avoid motor damage,
this motor should be blown out or
vacuumed frequently to keep
sawdust from interfering with normal
motor ventilation.
1.
Connect this tool to a 120V, 8A branch
circuit with a 8A time delay fuse or circuit
breaker. Using the wrong size fuse can
damage the motor.
2.
If the motor does not start,
turn
off the
toggle switch immediately. UNPLUG THE
TOOL. Check the saw blade to make sure
it turns freely. If the blade is free, try to
start the motor again.
3.
If the motor suddenly stalls while cutting
steel, turn the toggle switch off, unplug the
tool, and free the blade from the steel.
Then you may restart the motor and finish
the cut.
4. Fuses may “blow” or circuit breakers may
trip frequently if:
a.
Motor is overloaded-overloading can
occur if you feed too rapidly or make
too many start/stops in a short time.
b. Voltage not more than 10% above
or below the nameplate voltage can
handle normal loads. For heavy
loads, however, the voltage (caused
by a small size wire in the supply
circuit or an overly long supply
circuit wire) may drop too low for the
motor to operate. Always check the
connections, the load and the
supply circuit whenever motor does
not work well. Check wire sizes and
length with the Wire Size Chart
below.
5. Most motor troubles may be trace to
loose or incorrect connections, overload,
low voltage (such as small size wire in
the supply circuit) or to overly long supply
circuit wire. Always check the
connections, the load and the supply
circuit whenever motor doesn’t work well.
Check wire size and length with the Wire
Size Chart below
.
Wire Sizes
T
he use of any extension cable will cause
some loss of power. To keep this to a
minimum and to prevent overheating and
motor burn-out, use the table below to
determine the minimum wire size (lead
cross-section) of an extension cable.
For circuits that are more than
130'
away
from the electrical service box, the wire size
must be increased proportionately in order to
deliver ample voltage to the saw motor.
