3.0 Safety Warnings

1. Read and understand the entire owner’s manual before attempting assembly or operation.

2. Read and understand the warnings posted on the machine and in this manual. Failure to comply with all of these warnings may cause serious injury.

3. Replace the warning labels if they become obscured or removed.

4. This band saw is designed and intended for use by properly trained and experienced perso nnel on ly. If you are no t fam iliar w ith the proper and safe operation of a band saw, do not use until proper training and knowledge have been obtained.

5. Do not use this band saw for other than its intended use. If used for other purposes, JET disclaims any real or implied warranty and hold s itself harmles s from a ny injury t hat may result from that use.

6. Always wear ANSI approved safety glasses/face shields while using this band saw. Everyday eyeglasses only have impact resistant lenses; they are not safety glasses.

7. Before operating this machine, remove tie, rings, watches and other jewelry, and roll sleeves up past the elbows. Remove all loose clothing and confine long hair. Non-slip footwear or anti-skid floor strips are recommended.

8. Wear ear protectors (plugs or muffs) during extended periods of operation.

9. Some dust created by power sanding, sawing, grinding, drilling and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead based paint.

• Crystalline silica from bricks, cement and

other masonry products.

• Arsenic and chromium from chemically

treated lumber.

Your risk of exposure varies, depending on how often you do this type of work. To reduce your exposure to these chemicals, work in a well-ventilated area and work with approved safety equipment, such as face or dust masks that are specifically designed to filter out microscopic particles.

10. Do not operate this machine while tired or under the influence of drugs, alcohol or any medication.

11. Make certain the switch is in the OFF position before connecting the machine to the power supply.

12. Make certain the machine is properly grounded.

13. Make all machine adjustments or maintenance with the machine unplugged from the power source.

14. Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting wrenches are removed from the machine before turning it on.

15. Keep safety guards in place at all times when the machine is in use. If removed for maintenance purposes, use extreme caution and replace the guards immediately after maintenance is complete.

16. Make sure workpiece is securely clamped in the vise. Never use your hand to hold the workpiece.

17. Check coolant level frequently. Replace dirty or weak coolant.

18. Check damaged parts. Before further use of the machine, 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.

19. Inspect blade for cracks, wear or missing teeth. Replace blade if these symptoms are found.

20. Provide for adequate space surrounding work area and non-glare, overhead lighting.

21. Keep the floor around the machine clean and free of scrap material, oil and grease.

22. Keep visitors a safe distance from the work area. Keep children away.

23. Make your workshop child proof w ith padlocks, master switches or by removing starter keys.

24. Give your work undivided attention. Looking around, carrying on a conversation and “horseplay” are careless acts that can result in serious injury.

25. Maintain a balanced stance at all times so that you do not fall or lean against the blade or other moving parts. Do not overreach or use excessive force to perform any machine operation.

26. Use the right tool at the correct speed and feed rate. Do not force a tool or attachment to do a job for which it was not designed. The right tool will do the job better and more safely.

27. Use recommended accessories; improper accessories may be hazardous.

28. Maintain tools with care. Keep blades sharp and clean for the best and safest performance. Follow instructions for lubricating and changing accessories.

29. Turn off the machine and disconnect from power before cleaning. Use a brush to remove chips or swarf — do not use your hands.

30. Do not stand on the machine. Serious injury could occur if the machine tips over.

31. Never leave the machine running unattended. Turn the power off and do not leave the machine until it comes to a complete stop.

32. Remove loose items and unnecessary work pieces from the area before starting the machine.

7.0 Set-Up and Assembly

7.1 Unpacking and cleanup

Insp ect co nte nt s of sh ipp ing co nta ine r f or ship pi ng damage. Report any damage to your distributor.

Remove all contents from carton, and compare to the contents list in this manual. Report any part shortages to your distributor. Do not discard carton or packing material until machine is assembled and running satisfactorily.

Exposed metal areas have a rust preventative applied. Remove this with a soft rag a nd solvent or degreaser. Do not use cellulose-based solvents such as paint thinner or lacquer thinner; these will damage painted and plastic surfaces.

7.2 Shipping contents

If you do not see a part below, check the machine; some parts may have come pre-assembled to t he saw.

7.3 Assembly

Refer to Figure 4.

Figure 4

7. Remove stop bolt (X, Figure 4) and remove shipping bracket (Y). Retain bracket in case you must transport the machine in the future. Reinstall stop bolt.

Band Saw should be

disconnected from electrical power during assembly and setup.

1. Remove brackets holding saw to pallet.

2. Use properly rated lifting equipment (hoist or forklift) with straps placed beneath cast iron portion of saw.

3. Use blocking beneath saw, and install foot stand (H). Secure with four screws and washers (HP-1/2/3).

4. Install axle and wheels (F/G). Install cotter pin (HP-8) through hole in axle, and bend back legs of cotter pin to secure each wheel.

5. Slide workstop rod (B) into hole on saw base and slide workstop (A) onto rod. (NOTE: Do not insert rod too far so that it hits the vise leadscrew).

6. Install handle (E), and place filter screen (C) over coolant drain hole in pan.

After removal of shipping bracket (Y), the stop bolt (X) must be reinstalled and properly adjusted to prevent damage to the on/off switch.

7.4 Vertical cutting plate

These steps are only necessary when using band saw in vertical pos ition.

1. Disconnect machine from power source.

2. Raise bow to vertical position.

3. Remove two screws and remove seat plate, as

shown in Figure 5.

Figure 5

4. Guide blade through slot in vertical cutting plate (D, Figure 5), and tighten with the two screws.

5. Verify that vertical cutting plate is square to blade, using a machinist’s square on the plate and against the blade (Figure 6).

Figure 6

6. If adjustment is needed, loosen screws and place shims where required. Tighten screws.

Figure 8

7.5 Coolant system

Make sure there is coolant in

the tank before operating, to prevent damage to pump.

Use of a water-soluble coolant will increase cutting efficiency and prolong blade life. Do not use black cutting oil as a substitute.

1. Remove coolant return hose (A, Figure 9) from filter cup, and slide tank out of saw base.

2. Fill tank to approximately 80% of capacity. Full capacity is 9 liters (2.25 gal).

3. Place tank into base. Place coolant return hose into the filter cup. Verify that opposite end of coolant return hose is connected to the coolant pan.

4. The coolant supply hose (B, Figure 9) should connect to the taps on the blade guide assemblie s.

7. Place a level on vertical cutting plate (Figure

7).

Figure 7

8. Turn stop screw (J, Figure 8) as needed, until cutting plate is level. Tighten hex nut.

9. Close valve on c ylinder (lever perpendic ular to cylinder) to secure bow in position.

Reinstall seat plate before using bow in horizontal position.
