Operation

 

 

 

 

 

 

The load meter shown in Figure 16 displays the current amperage draw of the sanding belt motor. The needle rises when you increase the load on the sanding belts and decreases when you decrease the load. Use this meter to avoid over- loading your machine with too heavy of a cut.

NEVER exceed 30 amps—this is the maxi- mum that your machine can safely handle!

Since various types of stock will react differently to various loads, use trial-and-error to determine the best settings for your applications. As a gen- eral rule, always start with a small load and work your way up. DO NOT push your machine to its maximum load; instead, use multiple passes or install a coarser grit paper.

Long term exposure to this machine while oper- ating may cause hearing loss. Wear approved hearing protection to minimize this risk!

Under most sanding conditions, a normal cut is no more than .5mm (approx. 1Ú64"). This depth can be achieved by 1Ú8th turn of the conveyor height handle. Attempts to remove too much can cause jamming, wood burning, rapid paper wear or tear- ing, poor finish and belt slippage. For each pass, turn the stock 180¡ to ensure an even cut.

Make sure any stock that you run through the sander is clean and free of any defects or for- eign materials that might damage the sand- ing or conveyor belt.

NOTICE

We strongly recommend sending wide stock through the sander two or three times after the correct height has been estab- lished. This is an important step to prevent burning your wood or ruining sandpaper.

The following is the correct start-up and oper- ating procedure:

1.Start the dust collector.

2.Make the thickness adjustment by placing the workpiece on the conveyor table and turn ing the conveyor handle until the workpiece can be sanded and fed through smoothly. Turning the handle clockwise will raise the conveyor table. Turning the conveyor handle counter-clockwise will lower the conveyor table.

3.Remove the workpiece from the conveyor belt.

4.Start the sander and feed your stock. Retrieve by standing at the sideÑnot at the outfeed end.
