Some dust created by power sanding sawing, grinding, drilling, and other construction activities contains chemicals
known [to the State of California] to cause cancer, birth defects or other reproductive harm. Some examples of these
chemicals are:
® Lead from lead-based paints.
@ Crystalline silica from bricks and cement and other masonry products, and
@ Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to
these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks
that are specially designed to filter out microscopic particles.

GENERAL SAFETY INSTRUCTIONS
;! i
BEFORE USING THE BAND SAW
Safety is a combination of common sense, staying alert and
knowing how to use your band saw.
To avoid mistakes that could cause serious injury, do not
plug the band saw in until you have read and understood the
following:
1. READ and become familiar with this entire instruction
manual. LEARN the tool's applications, limitations, and
possible hazards.
2. KEEP GUARDS IN PLACE and in working order.
3. REMOVE ADJUSTING KEYS AND WRENCHES. Form
the habit of checking to see that keys and adjusting
wrenches are removed from the tool before turning ON.
4. KEEP WORK AREA CLEAN. Cluttered areas and
benches invite accidents.
5. DON'T USE IN A DANGEROUS ENVIRONMENT. Don't
use power tools in damp or wet locations, or expose
them to rain. Keep work area well lighted.
6. KEEP CHILDREN AWAY. All visitors should be kept at a
safe distance from the work area.
7.

safer at the rate for which it was designed.
9.
USE THE RIGHTTOOL. Don't force the tool or the
attachment to do a job for which it was not designed.
10.
USE PROPER EXTENSION CORD. Make sure your
extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to
carry the current your product will draw. An undersized
cord will result in a drop in line voltage and loss of power
which wilt cause the tool to overheat. The table on page
5 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 numbeq the
heavier the cord.

ELECTRICAL REQUIREMENTS
POWER SUPPLY AND MOTOR SPECIFICATIONS
To avoid electrical hazards, fire hazards, or damage to the
tool, use proper circuit protection. Use a separate electrical,
circuit for your tools. Your saw is wired at the factory for
120V operation. Connect to a 120V, 15 Amp circuit and use
a 15 Amp 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
This tool must be grounded while in use to protect the
operator from electrical shock.
This tool is intended for use on a circuit that has a
receptacle like the one illustrated in FIGURE A. FIGURE A
shows a 3-prong electrical plug and receptacle that has a
grounding conductor, tf a properly grounded receptacle is
not available, an adapter (FIGURE B) can be used to
temporarily connect this plug to a 2-contact ungrounded
receptacle. The adapter (FIGURE B) has a rigid lug
extending from it that MUST be connected to a permanent
earth ground, such as a properly grounded receptacle box.
THE TEMPORARY ADAPTER SHOULD BE USED ONLY
UNTIL A PROPER GROUNDED OUTLET CAN BE
INSTALLED BY A QUALIFIED ELECTRICIAN. The
Canadian Electrical Code prohibits the use of adapters.
CAUTION: In all cases, make certain the receptacle is

IN THE EVENT OF A MALFUNCTION OR BREAKDOWN,
grounding provides a path of least resistance for electric
current and reduces the riskof electric shock. This toolis
equipped with an electriccord that h_s an equipment
groundingconductor 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 MODIFYTHE 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 electric 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 sure the tool is properly grounded.
USE ONLY 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept the
tool's plug. Repair or replace damaged or worn cord
immediately.
Use a separate electrical circuit for your tools. This circuit
must not be less than #12 wire and should be protected with
a 15 Amp time lag 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.
