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 specic 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 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
1

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 qualied 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 at surface, unless a suitable
support is used.

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 oor.
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 qualied 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 qualied 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 qualied 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.
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 t the outlet, have the proper outlet installed by a
qualied electrician.
Improper connection of the equipment-grounding conductor can result In a risk of electric shock.
3

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 qualied 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 Sketch A
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 qualied 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 conguration 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 should be made by qualied service personnel;
and after reconnection, the tool should comply with all local codes and ordinances.

Quick release / blade tensioning
Lifting the quick release handle to release blade tension.
Remove blade and replace with new one. Turn down the
handle to tighten blade.
Turn the handle clockwise to minor tighten blade
tension and counterclockwise to release blade tension.
A blade under tension may also pull drive wheel out
of alignment. Adjust alignment of drive wheel with
tracking knob.

FIGURE 8-1
Adjusting blade support
Whenever changing a blade or adjusting tension and
tracking, the upper and lower blade support bearings
and guide blocks must be re-adjusted. Always adjust the
assemblies away from the blade before installing a new
blade or making blade tracking adjustments. After blade
tension and tracking are set correctly, re-adjust the upper
and lower support bearings and guide block assemblies
into position. See Figure 8-1 for upper blade guide and
Figure 8-2 for lower blade guide.
The support bearings back-up the blade during the
sawing operation. To adjust the support bearings, loosen
the screws the support bearing shafts. See Figure 8-3.
Adjust the shafts in or out so that the upper and lower
support bearings are within 1/64” of the back edge of the
blade. Retighten the screws.
For optimum support, the guide block assemblies should
be adjusted so they are just behind the gullet line (the
hollow points) of the blade. To adjust the guide block
assemblies, loosen the screws securing the guide block
yoke assemblies. Move in or out in relation to the blade
gullets. Once adjusted, retighten the screw.
Now adjust the guide blocks. Loosen the guide block
screws and adjust each block so it is about 0.004” from
the blade. This is about the same thickness as a piece
of typing paper. Retighten the screws and turn the
upper wheel by hand through a complete revolution for
the blade length to ensure that the blade weld passes
through the guide blocks unhindered.
