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

4. This band saw is designed and intended for use by properly trained and experienced personnel only. If you are not familiar with 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 holds itself harmless from any injury that may result from that use.

6. Always wear leather gloves when handling saw

blades. The operator shall not wear gloves when operating the machine.

7. Machinery must be anchored to the floor.

8. Secure work. Use clamps or a vise to hold work,

when practical. It is safer than using your hands and it frees both hands to operate the machine.

9. All doors shall be closed, all panels replaced,

and other safety guards in place prior to the machine being started or operated.

10. Be sure that the blade is not in contact with the

workpiece when the motor is started. The motor shall be started and you should allow the saw to come up to full speed before bringing the saw blade into contact with the workpiece.

11. Keep hands away from the blade area.

12. Remove any cut off piece carefully while

keeping your hands free of the blade area.

13. Saw must be stopped and electrical supply

must be cut off before any blade replacement or adjustment of blade support mechanism is done, or before any attempt is made to change the drive belts or before any periodic service or maintenance is performed on the saw.

14. Remove loose items and unnecessary

workpieces from area before starting machine.

15. Bring adjustable saw guides and guards as

close as possible to the workpiece.

16. Always wear protective eye wear when

operating, servicing, or adjusting machinery. Eyewear shall be impact resistant, protective safety glasses with side shields complying with ANSI Z87.1 specifications. Use of eye wear which does not comply with ANSI Z87.1 specifications could result in severe injury from breakage of eye protection.

17. Wear proper apparel. No loose clothing or

jewelry which can get caught in moving parts. Confine long hair.

18. Anti-skid floor strips, nonslip footwear and

safety shoes are recommended.

19. Wear hearing protection (plugs or muffs) if

sound reaches unsafe levels.

20. The workpiece, or part being sawn, must be

securely clamped before the saw blade enters the workpiece.

21. Remove cut off pieces carefully, keeping hands

away from saw blade.

22. Saw must be stopped and electrical supply cut

off or machine unplugged before reaching into cutting area.

23. Avoid contact with coolant, especially guarding

your eyes.

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

25. This saw must be grounded in accordance with

the National Electrical Code and local codes and ordinances. This work should be done by a qualified electrician. The saw must be grounded to protect the user from electrical shock. Caution: For circuits which are far away from the electrical service box, the wire size must be increased in order to deliver ample voltage to the motor. To minimize power losses and to prevent motor overheating and burnout, the use of wire sizes for branch circuits or electrical extension cords according to sect. 6.4, Table 2, is recommended.

26. Disconnect electrical power before servicing.

Whenever changing accessories or general maintenance is done on the machine, electrical power to the machine must be disconnected before work is done.

27. 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.

28. 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 completion of maintenance.

29. 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.

30. Maintain all machine tools with care. Follow all

maintenance instructions for lubricating and the changing of accessories.

31. No attempt shall be made to modify or have

makeshift repairs done to the machine. This not only voids the warranty but also renders the machine unsafe.

32. Keep work area clean. Cluttered areas invite accidents. Keep the floor around the machine clean and free of scrap material, oil and grease.

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

34. Make your workshop child proof with padlocks, master switches or by removing starter keys.

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

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

37. 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.

38. Use only recommended accessories; improper accessories may be hazardous.

39. Keep saw blades sharp and clean for the best and safest performance.

40. Turn off the machine before cleaning. Use a brush or vacuum to remove chips or debris — do not use bare hands. Never brush away chips while machine is in operation.

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

5.2 Tools required for assembly

All tools needed for assembly are provided with the machine. Additional tools may be necessary for maintenance and adjustments.

5.3 Uncrating and spotting

1. Finish uncrating the saw and inspect for damage. Should any have occurred, contact your local distributor. Do not discard packing material until saw is assembled and running satisfactorily.

2. Compare contents of shipping crate with the contents list in sect. 5.1. Report shortages, if any, to your distributor.

3. Remove four screws holding machine to shipping pallet.

4. Use lifting straps that are isolated from the band saw’s finished surfaces and clear of any handles or levers; lift machine and place in desired location. The band saw should be located on a solid and level foundation for best performance. When determining location, allow room for servicing and moving large stock around the machine.

NOTE: Motor installation requires 2 persons.

1. Unbolt motor assembly from shipping pallet.

2. Remove nut and washer from motor support shaft, and slide out support shaft (A, Figure 5-

2).

Figure 5-2: motor installation

3. Carefully lift motor and align holes in motor mounting plate and motor bracket.

4. Slide motor support shaft through motor mount bracket to secure motor in place. Use a rubber mallet if needed to tap shaft through the holes.

5. Reinstall nut and washer onto shaft.

6. Attach motor tilt plate (B, Figure 5-3) to motor bracket using the provided locking handle (C, Figure 5-3) with lock washer and flat washer.

Note: Locking handle (C) is adjustable. Pull out on handle and rotate it on the pin to a more convenient position, then release it. Make sure it reseats on the pin.

5.4.2 V-belt and pulley cover

1. Loosen tilt locking handle (C, Figure 5-3), and allow motor to lower. Place v-belt around both pulleys.

2. Push up motor and tighten tilt locking handle (C) to tension v-belt. Correct tension is achieved when finger pressure midway between the two pulleys causes approximately 1/2” deflection. See Figure 5-4.

3. Remove two hex cap bolts and washers (D, Figure 5-4).

4. Position belt cover (E, Figure 5-4) around pulley shafts and attach to saw with the two bolts and washers.

5. Close pulley cover and fasten with knob.

Cutting fluid/coolant must be supplied by the operator. See sect. 11.0.

6.0 Electrical connections

Electrical connections must be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded while in use to protect the operator from electrical shock and possible fatal injury.

The HBS-916EVS and HBS-1018EVS are prewired for single phase, 115 volt incoming power. The inverter converts the incoming current to the 230 volt required by the three phase motor. Confirm that power available at the saw’s location matches that for which the saw is wired.

An unattached power cable with plug is provided with the machine. The user may connect the 115V power cable, or “hardwire” the machine directly to an electrical panel. If hardwiring to a panel, a disconnect between panel and machine must be made available to the operator.

Before wiring, make sure saw is disconnected from power source or the fuses have been removed or breakers tripped in the circuit to which the saw will be connected. Use appropriate Lock-Out/Tag-Out

procedures.

6.1 Connecting motor cable

1. Loosen strain relief nut on motor junction box.

Remove junction box cover.

2. Insert motor cable (see F, Figure 5-2) through

strain relief and connect the leads inside the box. Make sure the grounding wire is properly connected.

3. Tighten strain relief nut and replace junction box

cover.

Figure 5-4: installing belt and pulley cover

5.5 Control box

Mount the control box atop the bow using the screws that are preinstalled in the two holes.

5.6 Lubrication

The band saw is shipped with the appropriate level of gear oil. The operator should verify this before using the saw, by checking the sight glass. (See Figure 11-2 for location.)

6.2 Connecting power cable

1. On right side of base, loosen strain relief nut on

junction box. Remove junction box cover.

2. Insert power cable through strain relief and

connect the leads inside the box. Make sure the grounding wire is properly connected.

3. Tighten strain relief nut and replace junction box

cover.

6.3 GROUNDING INSTRUCTIONS

This machine must be grounded. 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 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. Failure to comply may cause serious or fatal injury.

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.

This tool is for use on a nominal 120-V circuit, and has a grounded plug that looks like the plug illustrated in A, Figure 6-1. A temporary adaptor that looks like the adaptor illustrated in B and C may be used to connect this plug to a 2-pole receptacle as shown in B if a properly grounded outlet is not available.

The temporary adaptor should be used only until a properly grounded outlet (A, Figure 6-1) can be installed by a qualified electrician. The green colored rigid ear, lug, or the like extending from the adaptor must be connected to a permanent ground such as a properly grounded outlet box cover. Whenever the adaptor is used, it must be held in place by a metal screw.

In Canada, the use of a temporary adaptor is not permitted by the Canadian Electrical Code, C22.1.

6.4 Extension cords

The use of extension cords is discouraged; try to position machines near the power source. If an extension cord is necessary, make sure it 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 2 shows correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.
