PERSONAL SAFETY

CAUTION! Wear protective equipment approved by the Canadian Standards Association (CSA) or American

National Standards Institute (ANSI) when using the tool.

1. Dress properly, wear protective equipment. Use breathing, ear, eye, face, foot, hand, and head protection.

Always wear ANSI approved impact safety goggles, which must provide both frontal and side protection.

Protect your hands with suitable gloves. Wear a full face shield if your work creates metal ﬁlings or wood

chips. Protect your head from falling objects by wearing a hard hat. Wear an ANSI approved dust mask

or respirator when working around metal, wood and chemical dusts and mists. Wear ANSI approved

earplugs. Protective, electrically non-conductive clothes and non-skid footwear are recommended when

working. Wear steel-toed boots to prevent injury from falling objects.

2. Control the tool, personal movement and the work environment to avoid personal injury or damage to the

tool. Stay alert, watch what you are doing and use your common sense.

3. Keep articles of clothing, jewellery, hair, etc., away from moving parts to avoid entanglement with tool.

4. Do not operate any machine / tool when tired or under the inﬂuence of drugs, alcohol or medications.

5. Do not overreach when operating a tool. Proper footing and balance enables better control of a tool in

unexpected situations.

6. Use clamps or other practical ways to support or secure the work piece to a stable platform. Holding the

work piece by hand or against your body is not stable and may lead to loss of control and injury.

SPECIFIC SAFETY PRECAUTIONS

1. Accessories must be rated for at least the recommended RPM speed of the tool. See the Speciﬁcations

section for the no load speed.

2. Keep hands away from cutting area and the blade. If both hands are holding the saw, the blade cannot

cut them.

3. Keep your body positioned to either side of the blade, but not in line with the saw blade.

4. Keep the guards in place and in working order. Do not remove or modify any of the safety

features of the tool.

5. Never hold a work piece being cut in your hands. Secure the work piece to a stable platform. It is important

to support the work piece properly to minimize body exposure, blade binding, or loss of control.

6. Feed the work piece into a blade or cutter against the rotating direction of the blade or cutter.

7. Stay clear of end pieces that may fall after cutting. They may be hot, sharp and / or heavy. Serious personal

injury may result.

8. Never stand on the tool. Serious injury could occur if the tool is tipped or if the saw blade is accidentally

touched. To avoid having to stand or lean over the tool, do not store materials above or near it.

9. Be careful when moving the tool. Always turn off the power and lower the head to its horizontal position

before moving the saw unit.

9. Always handle the saw blade with care when mounting or removing it.

10. Do not start the tool when the blade is touching the work piece.

11. Never use damaged or incorrect blade washers or bolt. The blade washers and bolt were specially

designed for your saw, for optimum performance and safety of operation.

12. Do not use the tool on any material containing asbestos.

13. Avoid cutting nails. Inspect the work piece for any nails and remove before cutting.

14. Do not touch the blade or the surface that has been cut with this tool immediately after use. The surface

will be hot and may cause an injury.

ELECTRICAL SAFETY

1. Disconnect power supply. Disconnect the tool from the power supply when not in use, before cleaning,

servicing or changing any parts.

2. Protect yourself against electric shocks when working on electrical equipment. Avoid body contact with

grounded surfaces such as pipes, radiators, cooking stoves and refrigerators. There is an increased

Heavy Duty 7 in. Metal Cutting Band Saw

3460015

V 3.03

chance of electrical shock if your body is grounded.

3. Double insulated tools are equipped with a polarized plug (one blade is wider than the other.) This plug

will ﬁt in a polarized outlet only one way. If the plug does not ﬁt fully in the outlet, reverse the plug. If

it still does not ﬁt, contact a qualiﬁed electrician to install a polarized outlet. Do not change the plug in

any way. Double insulation eliminates the need for a three wire grounded power cord and grounded

power supply system.

4. Grounded tools must be plugged into an outlet that is properly installed and grounded in accordance with

all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use

any adapter plugs. Check with a qualiﬁed electrician if you are in doubt as to whether the outlet is properly

grounded. If the tool should electronically malfunction or break down, grounding provides a low resistance

path to carry electricity away from the user.

5. Do not abuse the cord. Never use the cord to pull the plug from an outlet. Keep the cord away from heat,

oil, sharp edges or moving parts. Do not operate this tool if the power cord is frayed or damaged. Replace

damaged cords immediately. Damaged cords increase the risk of electric shock. Do not modify the plug in

any way.

6. When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”. These cords

are rated for outdoor use and reduce the risk of electric shock. Use in conjunction with a Ground Fault

Circuit Interrupter (GFCI). If operating a power tool in a damp location is unavoidable, the use of a GFCI

reduces the risk of electric shock. It is recommended that the GFCI should have a rated residual current of

30 mA or less.

7. Avoid using an unnecessarily long extension cord. Choose a cord that is appropriate for the situation, as a

cord that is too long and running across the ﬂoor can be more dangerous than helpful. Using a cord that is

too long or too thin could damage the tool. Unroll the cord completely to prevent it from overheating.

8. Place the electrical cord in a position that prevents it from coming into contact with the tool and from

getting caught by the work piece. The cord should always stay behind the tool.

9. Keep all connections dry and off the ground to reduce the risk of electric shock. Do not touch the plug with

wet hands.

WARNING! People with pacemakers should consult their physician(s) before using this product. Operations

of electrical equipment in close proximity to a heart pacemaker could cause interference or failure

of the pacemaker.

KICKBACK PRECAUTIONS

Kickback is a sudden reaction to a pinched, bound or misaligned saw blade; − when the blade is pinched or bound

tightly by the kerf closing down, the blade stalls and the motor reaction drives the unit rapidly back. Kickback

may result in loss of control of the tool leading to serious personal injury and / or damage to the work piece

and / or tool.

Kickback can be avoided by taking proper precautions:

1. Maintain a ﬁrm grip on the tool / work piece and position your body and arms to allow you to resist

kickback forces.

2. Never place your hand near the blade. Use clamps or a vice to hold down the work piece.

3. Use special care when working on corners, sharp edges etc. Corners, sharp edges or bouncing have a

tendency to snag the blade and cause loss of control or kickback.

4. When the blade is binding, or when interrupting a cut for any reason, cut the power and hold the saw

motionless in the material until the blade comes to a complete stop. Never attempt to remove the work

piece from the saw while the blade is in motion or kickback may occur. Investigate and take corrective

actions to eliminate the cause of blade binding.

5. When restarting a saw in the work piece, center the saw blade in the kerf and check that saw teeth are not

engaged into the material. If saw blade is binding, it may walk up or kickback from the work piece as the

saw is restarted.

V 3.03

6. Support large panels to minimize the risk of blade pinching and kickback. Large panels tend to sag under

their own weight. Supports must be placed under the panel on both sides, near the line of cut and near the

edge of the panel.

7. Only use blades designed for the tool. Do not use dull or damaged blades. Unsharpened or improperly set

blades produce narrow kerf causing excessive friction, blade binding and kickback. Keep blades sharp and

clean. Gum and wood pitch hardened on blades slows the saw and increases potential for kickback.

8. Never force the cut. Forcing the saw can cause uneven cuts, loss of accuracy, and possible kickback.

VIBRATION PRECAUTIONS

This tool / work piece vibrates during use. Repeated or long-term exposure to vibration may cause temporary or

permanent physical injury, particularly to the hands, arms and shoulders.

1. Anyone using vibrating tools regularly or for an extended period should ﬁrst be examined by a doctor and

then have regular medical check-ups to ensure medical problems are not being caused by or worsened

from vibrations. Pregnant women or people who have impaired blood circulation to the hands, past hand

injuries, nervous system disorders, diabetes or Raynaud’s Disease should not use tool’s that vibrate. If you

feel any medical symptoms related to vibrations (such as tingling, numbness, and white or blue ﬁngers),

seek medical attention as soon as possible.

2. Do not smoke during use. Nicotine reduces the blood ﬂow to the hands and ﬁngers, increasing the risk of

vibration-related injury.

3. Wear suitable gloves to reduce the vibration effects on the user.

4. Use tools with the lowest amount of vibration when there is a choice between different processes.

5. Do not use for extended periods. Take frequent breaks when using vibrating tools.

6. Let the tool do the work. Grip the tool as lightly as possible (while still keeping safe control of it).

7. To reduce vibrations, maintain the tool as explained in this manual. If abnormal vibrations occur, stop

using this tool immediately.

3. Loosen the hex head screw in the tilting mechanism but do not remove it.

4. With the machine running, adjust both the set screw (167) and the blade tension knob (181)

simultaneously to keep constant tension on the blade. The set screw and blade tension knob always turn

in the opposite direction. i.e., When one is turned clockwise, the other is turned counterclockwise. The

blade is tracking properly when the back side just touches the shoulder of the puller or when a slight gap

appears near the center line of the pulley. Be careful not to over tighten the saw blade.

5. Tighten the hex head screw in the tilting mechanism.

CAUTION! Sometimes, while trying to make this critical adjustment, it is possible to cause an accidental

misalignment of the pieces of the tool. Should this occur, proceed as follows:

a. Loosen the set screw as far as it can go while remaining in the threaded hole.

b. Turn the hex head screw in the tilting mechanism clockwise until it stops (do not tighten).

c. Turn the set screw clockwise until it hits the bottom, then continue for half a turn and check the

tracking by turning on the machine.

d. If further adjustment is required, go back to step 4 and repeat the process.

6. Unplug the band saw.

7. Replace the blade guide assemblies – it may be necessary to loosen the blade tension slightly.

8. Adjust the vertical position of the blade guide bearing assemblies so that the back side of the blade just

touches the ball bearings.

9. Make a ﬁnal run to check the tracking. If further adjustment is required, go back to step 4 and

repeat the process.

10. Replace the blade guards.
