Controls and Indicators, Blade Speeds

2.Place a warning placard or tag on the service panel to prevent accidental electrical shock.

3.When installing the motor power cord into a receptacle, make sure the plug is compatible with the receptacle.

4.When using hard-wired connections, connect the wires as shown in the Wiring Data section.

5.Install the fuses or reset the breakers. Check operation of the saw.

Controls and Indicators

Control Panel

The operating controls for the cut-off saw are located on the control panel (Figure 5) and consist of the following controls and indicators:

Coolant Pump Switch – turns the coolant pump on and off.

Emergency Stop Switch – press to stop the drive motor. Note: A micro switch also stops the motor when the workpiece is cut and the saw head is completely down.

Start Switch – press to start the drive motor. The saw head must be in the raised position.

Power Light – indicates that machine is plugged in and the outlet circuit breaker is turned on. The machine does not need to be running for the power light to be on.

Feed Rate Control – this knob is used to set the amount of downward force that is applied to the saw blade. The feed rate is proportional to the opening of the valve. When set to zero, the saw head is locked in the raised position. Increasing the valve opening (counterclockwise adjustment) increases the feed rate; decreasing the valve opening (clockwise adjustment) reduces the feed rate.

Blade Speeds

The Model 7015 horizontal cut-off bandsaw has four blade speeds. The different speeds are obtained by changing the position of the motor drive V-belt on step pulleys. Change blade speeds as follows:

1.Disconnect the electrical power from the cut-off saw branch circuit to prevent accidental motor start-up

2.Set the saw head at the fully down position.

3.Remove the knob from the drive belt cover. Swing cover out and downward to expose the V-belt and pulleys.

4.Loosen the drive motor locking handle. Pivot the motor inward to slacken the belt.

5.Select the speed using the placard on the cover. Put the V-belt in the pulley grooves of the pulley for the desired speed. Refer to Figure 6 for belt locations and the speeds available.

6.Pivot the motor outward to tighten the V-belt. Tighten the locking handle.

7.Check V-belt tension by pushing the V-belt firmly downward; press down about midway between the pulleys. When properly tight- ened, the V-belt should depress no more than the width of the belt.
