8.5Feed speed adjustment
The Model 1632 has two speeds that feed the workpiece at 15 feet per minute (FPM) finished surface sanding, and 32.5 FPM for faster, lighter sanding.
To change the feed rate:
1.Disconnect machine from power source.
2.Remove cap screw that holds the sprocket cover at the right rear of the working table.
3.Loosen the four set screws holding the sprockets in place.
4.Remove the sprockets and chain together and position according to the required operation. See Figure 6.
5.Retighten the four set screws, then replace cover and cap screw.
9.0Operation
9.1Controls
(see Figure 7):
Emergency stop (A) will stop the feeding belt and sanding belt. The button must be turned clockwise to reset sanding functions.
Amp Meter (B) displays the amperage. Feeding Start (C) will start the feeding belt only. Feeding Stop (D) will stop the feeding belt only.
Sanding Belt Start (E) will start the sanding belt only.
Sanding Belt Stop (F) will stop the sanding belt only.
NOTE: The orange bar on the front of the infeed roller acts as a safety stop. When the bar is pressed, the brakes are applied.
1.Connect the air line to the sander.
2.Adjust the pressure gauge to 75 psi.
3.Engage the upper roller by turning the knob (A), Figure 8, to the upper position.
4.Adjust the platen with the lever (B) and lock it
(C)in the desired position. The platen or main rubber roller can act as the sanding contact, as well as a combination of both.
5.Rotate the main handwheel (A), on the lower cabinet, to raise or lower the table. See Figure
9. Refer to the scale for the desired setting. The recommended depth of sanding is .0164" or two revolutions of the handwheel. The table can be locked in place by the lever at the base of the column.
6.Turn on the power to the machine.
7.Start the sanding belt.
8.Start the feeding conveyor.
NOTE: If you are sanding a workpiece greater than 16 inches, pull out the support extension, and tighten the wing nuts. After the first pass, the workpiece can be spun around and fed back through the machine, for a maximum sanding width of 32 inches.
10.0Maintenance
Before performing any maintenance on the sander, disconnect it from the electrical supply by pulling out the plug or switching off the main switch. Failure to comply may cause serious injury.
The interior of the machine should be thoroughly cleaned each day after using the sander.
Remove the sanding belt before cleaning and re- install it when finished.
Keep the sanding belt clean using cleaning sticks or pads (not provided).
Blow dust off the conveyor belt with compressed air or use a dust collector vacuum attachment.
The drum bearings should be greased (via grease fittings on each side) after every 150 work hours.
