Electrical Requirements And Safety - KNOVA KN M-2504RC Manual

TABLE SAW SAFETY
c. Keep saw blade guard assembly, riving knife and
anti-kickback assembly in place and operating properly.
If anti-kickback assembly is not operational, return your
unit to the nearest authorized service center for repair.
The riving knife must be in alignment with the saw blade
and the anti-kickback pawls assembly must stop a
kickback once it has started. Check their action before
ripping by pushing the wood under the anti-kickback
assembly. The teeth must prevent the wood from being
pulled toward the front of the saw.
d. Plastic and composite (like hardboard) materials may be
cut on your saw. However, since these are usually quite
hard and slippery, the anti-kickback pawls may not stop a
kickback. Therefore, be especially attentive to following
proper set up and cutting procedures for ripping.
e. Use saw blade guard assembly, anti-kickback pawls
assembly and riving knife for every operation for which it
can be used, including all through-sawing.

ELECTRICAL REQUIREMENTS AND SAFETY

POWER SUPPLY AND MOTOR SPECIFICATIONS
WARNING
To avoid electrical hazards, fire hazards, or
damage to the tool, use proper circuit protection. Your
saw is wired at the factory for 120 V operation.
Connect to a 120 V, 15 A circuit and use a 15 A time
delay fuse or circuit breaker. To avoid shock or fire,
if power cord is worn or cut, or damaged in any way,
have it replaced immediately.
GROUNDING INSTRUCTIONS
WARNING
This tool must be grounded while in use
to protect the operator from electrical shock.
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN,
grounding provides a path of least resistance for electric
currents and reduces the risk of electric shock. This tool is
equipped with an electrical cord that has an equipment
grounding conductor and a grounding plug. The plug must be
plugged into a matching receptacle that is properly installed
and grounded in accordance with all local codes and ordinances.
DO NOT MODIFY THE PLUG PROVIDED. If it will not fit
the receptacle, have the proper receptacle installed by a
qualified electrician.
IMPROPER CONNECTION of the equipment grounding
conductor can result in risk of electric shock. The conductor
with the green insulation (with or without yellow stripes) is
the equipment grounding conductor. If repair or replacement
of the electrical cord or plug is necessary, do not connect the
equipment grounding conductor to a live terminal.
CHECK with a qualified electrician or service person if you do
not completely understand the grounding instructions, or if
you are not certain the tool is properly grounded.
USE only 3-wire extension cords that have three-pronged
grounding plugs with three-pole receptacles that accept
the tool's plug. Repair or replace damaged or worn cords
immediately.
Use a separate electrical circuit for your tool. This circuit must
not be less than # 14 wire and should be protected with a
15 Amp time delay fuse. Before connecting the motor to the
power line, make sure the switch is in the off position and the
electric current is rated the same as the current stamped on
the motor nameplate. Running at a lower voltage will damage
the motor.
f. Push the workpiece past the saw blade prior to release.
g. Never rip a workpiece that is twisted or warped, or does
not have a straight edge to guide along the fence.
h. Never saw a large workpiece that cannot be controlled.
i. Never use the fence as a guide or length stop when
crosscutting.
j. Never saw a workpiece with loose knots, flaws, nails or
other foreign objects.
k. Never rip a workpiece shorter than 10 in. (254 mm).
l. NEVER use a dull blade – replace or have resharpened.
m. NEVER use a rip fence and miter gauge together.
n. Keep hands out of saw blade.
USE THE PROPER EXTENSION CORD. Make sure your
extension cord is in good condition. Use an extension cord
heavy enough to carry the current your product will draw.
An undersized cord will cause a drop in line voltage resulting
in loss of power, overheating and burning out of the motor.
The table below shows the correct size to use depending on
cord length and nameplate ampere rating. If in doubt, use the
next heavier gauge. The smaller the gauge number, the
heavier the cord.
GUIDELINES FOR EXTENSION CORDS
Make sure your extension cord is properly wired and in good
condition. Always replace a damaged extension cord or have
it repaired by a qualified technician before using it. Protect
your extension cords from sharp objects, excessive heat and
damp or wet areas.

WARNING
This tool is for indoor use only. Do not
expose to rain or use in damp locations.
This tool is intended for use on a circuit that has a receptacle
like the one illustrated in Fig. 1. Fig. 1 shows a three-pronged
electrical plug and receptacle that has a grounding conductor.
If a properly grounded receptacle is not available, an adapter
(Fig. 2) can be used to temporarily connect this plug to a
two-contact grounded receptacle. The adapter (Fig. 2) has a
grounding lug extending from it that MUST be connected to
a permanent earth ground, such as a properly grounded
receptacle box.
CAUTION
In all cases, make certain the receptacle is
properly grounded. If you are not sure, have a qualified
electrician check the receptacle.
