The bottom row of controls include the following:
1.Stop pushbutton is used to stop the saw blade drive motor.
2.Emergency stop pushbutton is used to quickly disconnect electrical power to the machine.
3.Coolant On/Off selector switch is used to start and stop the coolant pump motor.
Other Controls
Refer to Figures 1 and 2 for location of the following controls:
1.Drive motor speed control: used to set drive motor speed in meters per minute.
2.Blade guide support adjustment: used to set distance between the saw blade guide bearing as required by the size of the workpiece.
3.Blade tensioning hand wheel: use to tighten the saw blade on the drive and idler wheels.
4.Vise clamping hand wheel: used to tighten the vise jaws against the workpiece.
Setting Blade Speed
1.The blade speed is controlled by an adjustment mechanism on the right end of the saw. Speed increases when the adjustment knob is turned counterclockwise. Speed decreases when the knob is turned clockwise.
2.A placard on the drive belt guard (shown below) provides recommended speeds for various materials.
3.A speed indicator is provided on the barrel of the adjustment mechanism. The indicator provides speed indications in feet per minute and meters per minute. (The meters per minute values are shown in parenthesis on the indicator.) The graduations are:
Feet per Minute | Meters per Minute |
70 | (21) |
100 | (30) |
130 | (40) |
160(48)
4.The feed rates on the placard are expressed in meters per minute. The feed rate graduations available on the indicator may not match the recommended feed rate. An approximate speed may therefore be required. For example, to set a speed rate of 25 meters per minute, the indicator would be set about midway between 21 meters-
WARNING: TO CHANGE SPEED, THE SAW MOTOR MUST BE OPERATING.
5.Turn the speed adjustment knob to the desired rate setting as determined by the material being cut.
Raising/Lowering the Saw Head
1.To raise the saw head, press the Saw Head Up pushbutton. The saw head will raise until the upper limit switch (refer to Figure 4) trips.
2.To lower the saw head, press the Saw Head Down pushbutton. The saw head will lower until the lower limit switch trips.
3.When the saw head is being lowered to cut a workpiece, the saw blade drive motor must be started before lowering the blade against the workpiece. Set the coolant pump selector to the on ( I ) position If coolant is required by the material being cut.
