GENERAL SAFETY RULES

Safety is a combination of common sense, staying alert and knowing how your item works. SAVE THESE SAFE-

TY INSTRUCTIONS.

WARNING: To avoid mistakes and serious injury, do not plug in your tool until the following steps

have been read and understood.

1. READ and become familiar with this entire instruction manual. LEARN the tool’s applications, limitations, and
possible hazards.

2. AVOID DANGEROUS CONDITIONS. Do not use power tools in wet or damp areas or expose them to rain.
Keep work areas well lit.

3. DO NOT use power tools in the presence of flammable liquids or gases.

4. ALWAYS keep your work area clean, uncluttered, and well lit. DO NOT work on floor surfaces that are slippery
with sawdust or wax.

5. KEEP BYSTANDERS AT A SAFE DISTANCE from the work area, especially when the tool is operating.
NEVER allow children or pets near the tool.

6. DO NOT FORCE THE TOOL to do a job for which it was not designed.

7. DRESS FOR SAFETY. Do not wear loose clothing, gloves, neckties, or jewelry (rings, watches, etc.) when op­erating the tool. Inappropriate clothing and items can get caught in moving parts and draw you in. ALWAYS wear
non-slip footwear and tie back long hair.

8. WEAR A FACE MASK OR DUST MASK to fight the dust produced by sawing operations.

WARNING: Dust generated from certain materials can be hazardous to your health. Always operate the
tool in a well-ventilated area and provide for proper dust removal. Use dust collection systems whenever
possible.

9. ALWAYS remove the power cord plug from the electrical outlet when making adjustments, changing parts,
cleaning, or working on the tool.

10. KEEP GUARDS IN PLACE AND IN WORKING ORDER.

11. AVOID ACCIDENTAL START-UPS. Make sure the power switch is in the OFF position before plugging in
the power cord.

12. REMOVE ADJUSTMENT TOOLS. Always make sure all adjustment tools are removed from the saw before
turning it on.

13. NEVER LEAVE A RUNNING TOOL UNATTENDED. Turn the power switch to OFF. Do not leave the
tool until it has come to a complete stop.

14. NEVER STAND ON A TOOL. Serious injury could result if the tool tips or is accidentally hit. DO NOT store
anything above or near the tool.

GENERAL SAFETY RULES

15. DO NOT OVERREACH. Keep proper footing and balance at all times. Wear oil-resistant rubber-soled foot­wear. Keep the floor clear of oil, scrap, and other debris.

16. MAINTAIN TOOLS PROPERLY. ALWAYS keep tools clean and in good working order. Follow instruc­tions for lubricating and changing accessories.

17. CHECK FOR DAMAGED PARTS. Check for alignment of moving parts, jamming, breakage, improper
mounting, or any other conditions that may affect the tool’s operation. Any part that is damaged should be properly
repaired or replaced before use.

18. MAKE THE WORKSHOP CHILDPROOF. Use padlocks and master switches and ALWAYS remove start­er keys.

19. DO NOT operate the tool if you are under the influence of drugs, alcohol, or medication that may affect your
ability to properly use the tool.

20. USE SAFETY GOGGLES AT ALL TIMES that comply with ANSI Z87.1. Normal safety glasses only have
impact resistant lenses and are not designed for safety. Wear a face or dust mask when working in a dusty environ­ment. Use ear protection such as plugs or muffs during extended periods of operation.

SPECIFIC RULES FOR BAND SAW

1. To avoid injury from unexpected movement, make sure the saw is on a firm, level surface, properly secured to
prevent rocking. Make sure there is adequate space for operations. Bolt the saw to a support surface to prevent slip­ping or sliding during operation.

2. Turn off and unplug the saw before moving it.

3. Use the correct size and style of blade.

4. Make sure the blade teeth point down and toward the table.

5. Blade guide, supports, bearings, and blade tension must be properly adjusted to avoid accidental blade contact
and to minimize blade breakage. To maximize blade support, always adjust the upper blade guide and blade guard
so that it barely clears the workpiece.

6. Table TILT lock handle should be tight and locked during operation.

7. Use extra caution with very large, very small, or awkwardly-shaped workpieces.

8. Use extra supports to prevent workpieces from sliding off the tabletop.

9. Workpieces should be secured so they don’t twist, rock, or slip while being cut.

10. Plan intricate or small work carefully to avoid pinching the blade. Avoid awkward operations and hand positions
to prevent accidental contact with the blade.

SPECIFIC RULES FOR BAND SAW

11. Small pieces should be secured with clamps or fixtures. Do not hold small pieces with your hand because your
fingers might go under the blade guard.

12. Support round work properly (use a V block or press it against the miter gauge) to prevent it from rolling and
the blade from biting.

13. Cut only one workpiece at a time. Make sure the table is clear of everything except the workpiece and its guides
before you turn the saw on.

14. Always WATCH the saw run before each use. If there is excessive vibration or unusual noise, stop immediately.
Turn the saw off. Unplug it immediately. Do not start the saw again until the problem has been located and cor­rected.

15. To free any jammed material, turn the switch off. Remove the switch key and unplug the saw. Wait for all mov­ing parts to stop before removing the jammed material.

16. Don’t leave the work area until all moving parts have stopped. Shut off the power to master switches. Remove
the switch key from the band saw and store it in a safe place, away from children. Childproof the workshop!

ELECTRICAL INFORMATION

GROUNDING INSTRUCTIONS

IN THE EVENT OF A MALFUNCTION OR BREAKDOWN, grounding provides the path of least resistance
for an electric current and reduces the risk of electric shock. This tool is equipped with an electric cord that has 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
licensed electrician.

IMPROPER CONNECTION of the equipment grounding conductor can result in 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 licensed electrician or service personnel if you do not com­pletely understand the grounding instructions or whether the tool is properly
grounded.

USE ONLY THREE-WIRE EXTENSION CORDS that have three-pronged
plugs and outlets that accept the tool’s plug as shown in Fig. A. Repair or re­place a damaged or worn cord immediately.

CAUTION: In all cases, make certain the outlet in question is properly grounded. If you are not sure, have a li­censed electrician check the outlet.

ELECTRICAL INFORMATION

WARNING: This tool is for indoor use only. Do not expose to rain or use in damp locations.

UL GUIDELINES AND RECOMMENDATIONS FOR EXTENSION CORDS

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. The table below shows the correct size to be used according to cord length and
nameplate ampere rating. When in doubt, use a heavier cord. The smaller the gauge number, the heavier the cord.

AMPERAGE

2.8 A 18 gauge 16 gauge 16 gauge 14 gauge

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 person before using it.

Protect your extension cords from sharp objects, excessive heat and damp/wet areas.

Use a separate electrical circuit for your tools. This circuit must not be less than a #12 wire and should be protected
with a 15 A time-delayed 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.

WARNING: This tool must be grounded while in use to protect the operator from electric shock.
