9.0 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.

Disconnect machine from power source befor e changing any voltage components!

The HBS-916W Band Saw is rated at 115/230V single phase, and is pre-wired 115 volt from the factory. The HBS-1018W is rated at 230V only, single phase. Confirm that power available at the saw’s location matches that for which the saw is wired.

To convert the HBS-916W from 115V to 230V , the following items will have to be changed:

Main Motor – follow diagram inside junction box cover.

Coolant Pump – Remove chip pan on front of saw, remove junction box cover on pump, and follow diagram inside junction box cover.

Control Transformer – Open electrical panel on rear of base and change the fuse from 115V to 230V.

Power Indicator Light (A) – lit whenever machine is running.

Start Button (B) – press to start band saw. Emergency Stop Button (C) – press to

immediately stop all machine functions. Coolant Switch (D) – Turn arrow to “I” to turn on

coolant flow. Turn arrow to “O” to stop coolant flow. Cutting Pressure Control (E) – turn clockwise to

decrease cutting pressure. Turn counter-clockwise to increase cutting pressure.

Hydraulic On-Off Valve (F) – turns hydraulic cylinder on and off.

11.0 Prior to Operation

1. Check that blade tooth direction matches diagram on blade guides.

2. Check to see that blade is properly seated on wheels after applying correct tension (approximately 25,000 lbs.).

3. Set blade holder guides for approximately .003” to .005” clearance between guides and blade.

4. Check for slight clearance between back up rollers and back of blade.

5. Position blade guides as close to workpiece as possible.

6. Select proper speed and f eed rate for m aterial being cut. See speed selection chart found in the enclosed “Guide to Band Sawing” booklet supplied with this saw.

7. Material to be cut must be securely held in vise.

8

8. Check to see that coolant level is adequate and turn on coolant pump if m aterial to be cut requires it. Machine should be filled with four gallons of the proper coolant mixture. Follow the directions on the product maker’s label and fill the coolant tank through the chip tray area.

9. Do not start cut on a sharp edge.

10. Keep machine lubricated. See “Lubrication” section.

12.0 Adjustments

12.1 Adjusting vise square to blade

1. Disconnect the machine from the power source.

2. Place a machinist’s square on the table against the blade and the vise. The square should lie along the entire length of the vise and blade without a gap.

3. If adjustment is necessary, loosen bolts holding the vise and adjust vise so square lines up properly. Tighten bolts.

4. Connect machine to the power source.

when finger pressure on the belt between the two pulleys causes approximately a 1/2" deflection.

6. Close pulley cover and fasten.

7. Connect machine to the power source.

12.3 Adjusting feed rate

Rate of feed is adjusted by turning the cutting pressure control knob on the control panel. Rate of feed is important to band saw performance; excessive pressure may break the blade or stall the saw. Insufficient pressure rapidly dulls the blade.

Material chips or shavings are the best indicator of proper speed and pressure. The ideal chip is thin, tightly curled, and warm to the touch. Chips that range from golden brown to black indicate excessive force. Blue chips indicate extreme heat from too high a band speed which will shorten blade life. Thin or powdered chips indicate insufficient feed pressure.
