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 toANSI 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 TOOL it 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. A
guard 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 TOOL RUNNING 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
1. If you are not thoroughly familiar with the operation of band saws, obtain
advice 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

3
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 from the 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.
ON-OFF SWITCH PADLOCK – To safeguard the band saw from unauthorized
operation and to avoid accidental starting by children or other not qualified to use,
the use of padlock is required. To lock out the on – off switch, open the padlock,
insert through the hole of the switch on button and close the padlock. Place the
key in a location that is inaccessible to children and other not qualified to use the
tool.
SWITCH WITH KEY – The switch key must be inserted into the switch before
saw can operate. To lock the switch in the OFF position, remove the switch key
from the switch. Place the key in a location that is inaccessible to children and
others not qualified to use the tool.
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.

4
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 A in Figure 1. The tool has a grounding plug that looks like the plug illustrated in
SketchA in Figure 1.A temporary 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 Sketch D in Figure 1. The tool has a grounding plug that looks like the plug illustrated in
Sketch D in Figure 1. Make sure the tool is connected to an outlet having the same
configuration as the plug. No adapter is available or should be used with this tool. If the
tool must be reconnected for use on a different type of electric circuit, the reconnection

5
should be made by qualified service personnel; and after reconnection, the tool should
comply with all local codes and ordinances.
Note : In Canada, the use of a temporary adaptor is not
permitted by the Canadian Electrical Code.
