SAFETY RULES
WARNING: FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS
PERSONAL INJURY.
1. FOR YOUR OWN SAFETY, READ INSTRUCTION MANUAL BEFORE OPERATING
THE TOOL. Learn the tool’s application and limitations as well as the specific hazards peculiar
to it.
2. KEEP GUARDS IN PLACE and in working order.
3. ALWAYS WEAR EYE PROTECTION. Wear safety glasses. Everyday eyeglasses only have
impact resistant lenses; they are not safety glasses. Also use face or dust mask if cutting operation
is dusty. These safety glasses must conform to ANSI Z87.1 requirements.
Note: Approved glasses have Z87 printed or stamped on them.
4. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys
and adjusting wrenches are removed from tool before turning it on.
5. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
6. DON’T USE IN DANGEROUS ENVIRONMENT. Don’t use power tools in damp or wet
locations, or expose them to rain. Keep work area well lighted.
7. KEEP CHILDERN AWAY. All visitors should be kept safe distance from work area.
8. MAKE WORKSHOP KID PROOF with padlocks, master switches, or by removing starter
keys.
9. DON’T FORCE TOOLit will do the job better and safer at the rate for which it was not
designed.
10. USE RIGHT TOOL. Don’t force tool or attachment to do a job for which it was not designed.
11. 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 cause a drop in line voltage resulting in loss of power and
overheating. Table 1 shows the correct size to use depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.
12. WEAR PROPER APPAREL Do not wear loose clothing, gloves, neckties, rings, bracelets, or
other jewelry which may get caught in moving parts. Nonslip footwear is recommended. Wear
protective hair covering to contain long hair.
13. ALWAYS USE SAFETY GLASSES.Also use face or dust mask if cutting operation is dusty.
Everyday eyeglasses only have impact resistant lenses, they are NOT safety glasses.
14. SECURE WORK. Use clamps or a vise to hold work when practical. It’s safer than using your
hand and it frees both hands to operate tool.
15. DON’T OVERREACH. Keep proper footing and balance at all times.

16. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest
performance. Follow instructions for lubricating and changing accessories.
17. DISCONNECT TOOLS before servicing; when changing accessories, such as blades, bits,
cutters, and the like.
18. REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure switch is in off
position before plugging in.
19. USE RECONNENDED ACCESSORIES. Consult the owner’s manual for recommended
accessories. The use of improper accessories may cause risk of injury or persons.
20. NEVER STAND ON TOOL Serious injury could occur if the tool is tipped or if the cutting tool
is unintentionally contacted.
21. CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is
damaged should be carefully checked to determine that it will operate properly and perform its
intended function-check for alignment of moving parts, binding of moving parts, breakage of parts,
mounting, and any other conditions that may affect its operation. Aguard or other part that is
damaged should be properly repaired or replaced.
22. DIRECTION OF FEED. Feed work into a blade or cutter against the direction of rotation of the
blade or cutter only.
23. NEVER LEAVE TOOLRUNNING UNATTENDED. TURN POWER OFF. Don’t leave tool
until it comes to a complete stop.
24. MAME SURE TOOL IS DISCONNECTED from power supply while motor is being mounted,
connected or reconnected. SAVE THESE INSTRUCTIONS
 ADDITIONAL SAFETY RULES FOR BAND SAWS

from your supervisor, instructor or other qualified person.
2. Follow all wiring codes and recommended electrical connections. Make certain that
the tool is properly grounded.
3. Make all adjustments with the power “OFF”
4. Always maintain proper adjustment of blade tension, blade guides, and blade
support bearings.
5. Avoid awkward hand positions. A sudden slip could allow the hand to contact the
blade.
6. Do not attempt to saw stock that does not have a flat surface, unless a suitable
support is used.
7. Make sure blade is not contacting the workpiece before turning on the power switch.
8. Always keep hands and fingers away fromthe blade when the machine is running.
9. Hold workpiece firmly against table and feed into blade at a moderate speed.

10.Made sure that the saw blade teeth point downward toward the table.
11.Adjust upper guide to just clear work piece.
12.Disconnect machine from the power source when making repairs.
13.Replace all guards after servicing.
14.Turn off band saw if the material is to be backed out of an uncompleted cut.
15.Make relief cuts before cutting long curves.
16.Do not cut material that is too small to be safely supported.
17.Support long heavy work from the floor.
18.Before leaving the machine, make sure the work area is clean.
19.Important: When the tool is not in use , the switch should be in the “OFF” position
and the power cord disconnected.
20.Do not remove jammed cutoff pieces until blade has stopped.
 GROUNDING INSTRUCTIONS
1. All grounded, cord-connected tools:
In the event of a malfunction or breakdown, grounding provides a path of least resistance for
electric current to reduce the risk of electric shock. This tool is equipped with an electric cord
having an equipment-grounding conductor and a grounding plug.
The plug must be plugged into a matching outlet 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 outlet, have the proper outlet installed by
a qualified electrician.
Improper connection of the equipment-grounding conductor can result In a risk of electric shock.

The conductor with insulation having an outer surface that is green 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 personnel if the grounding instructions are not
completely understood, or if in doubt as to whether 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.
2. Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating less
than 150 volts:
This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in
Sketch Ain Figure 1. The tool has a grounding plug that looks like the plug illustrated in Sketch A
in Figure 1. Atemporary adapter, which looks like the adapter illustrated in Sketches B and C, may
be used to connect this plug to a 2-pole receptacle as shown in Sketch B if a properly grounded
outlet is not available. The temporary adapter should be used only until a properly grounded outlet
can be installed by a qualified electrician. The green-colored rigid ear, lug, and the like, extending
from the adapter must be connected to a permanent ground such as a properly grounded outlet box.
3. Grounded, cord-connected tools intended for use on a supply circuit having a
nominal rating between 150-250 volts, inclusive:
This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in
