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 completion of maintenance.

16. 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.

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

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

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

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

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

22. 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.

23. 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.

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

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

26. Maintain proper adjustment of blade tension, blade guides and thrust bearings.

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

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

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

31. Never hand hold the material. Always use the vise and clamp it securely.

32. Be sure that blade is not in contact with workpiece when motor is started. Allow motor to come up to speed before bringing blade into contact with workpiece.

33. Avoid contact with coolant, especially guarding your eyes.

35. Do not remove jammed pieces until blade has stopped.

36. Don’t use in dangerous environment. Don’t use power tools in damp or wet location, or expose them to rain. Keep work area well lighted.

37. 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 2 (sect. 6.3) shows 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.

34. Never reach around or over saw blade during operation. Keep hands and fingers away from blade area.

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 to help prevent electrical shock and possible fatal injury.

The MBS-1018-1 Horizontal Band Saw is rated at single phase, 230V power only. The band saw comes with a plug designed for use on a circuit with a grounded outlet that looks like the one pictured in Figure 9-1.

It is recommended that the MBS-1018-1 band saw be connected to a dedicated 15-amp circuit with circuit breaker or time-delay fuse marked “D”. Local

codes take precedence over recommendations.

The MBS-1018-3 Horizontal Band Saw is rated at 3phase, 230/460V and is prewired for 230V. The MBS-1018-3 is not provided with an electrical plug; you may either attach a proper UL/CSA-listed plug, or “hardwire” the machine directly to a service panel.

It is recommended that the MBS-1018-3 band saw be connected to a dedicated 7-amp circuit with circuit breaker or time-delay fuse marked “D”. Local

codes take precedence over recommendations.

Before connecting to power source, be sure switch is in off position.

6.1 GROUNDING INSTRUCTIONS

This tool 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 ser ious 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 intended for use on a circuit that has an outlet that looks like the one illustrated in Figure 9-

1. The MBS-1018-1 has a grounding plug that looks like the plug illustrated in Figure 9-1. Make sure the tool is connected to an outlet having the same configuration 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 elec tric circuit, the reconnection should be made by qualified service personnel; and after reconnection, the tool should comply with all local codes and ordinances.

If hardwired:

Permanently connected tools: This tool should be connected to a grounded metal permanent wiring system; or to a system having an equipmentgrounding conductor. Make sure a disconnect is available for the operator. During hard-wiring of the machine, make sure the fuses have been removed or the breakers have been tripped in the circuit to which the drill press will be connected. ALWAYS FOLLOW PROPER LOCK-OUT/TAG-OUT PROCEDURES.

Figure 9-1: 230V plug and receptacle

6.2 Voltage conversion (MBS-1018-3

only)

1. Reconnect leads in motor junction box according to diagram inside junction box cover. Diagrams are also found at back of this manual. (If discrepancies should occur, diagrams on machine take precedence.)

2. Reconnect leads on transformer in electrical box.

3. Reconnect leads to coolant pump according to diagram inside pump junction box cover.

4. If using a plug, connect a proper UL-listed plug for the incoming voltage.

Make sure incoming current matches power requirements of saw. If saw blade does not move in proper direction, disconnect machine from power supply and reverse any two of the three power leads (except green ground wire).

6.3 Extension cords

The use of extension cords is discouraged; try to position equipment within reach of the power source. If an extension cord becomes necessary, be sure it is 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 recommended 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.
