W1772/W1773 37" Drum Sander Depth.of.Cut The optimum depth of cut will vary based on the type of wood, feed rate, and sandpaper grit. Under most sand- ing conditions, the depth should not exceed " (approx. turn of the handwheel). Each full turn of the table height handwheel raises the conveyor table approximately 0.020".
W1772/W1773 37" Drum Sander Using.the.Amp.Draw. Meter The amp draw meter (Figure.26) is used to keep machine from being overloaded during sanding operations. As a general rule, always start with a shallow sand- ing depth and carefully increase the sanding depth.

W1772/W1773 37" Drum Sander Conveyor.Tensioning.&. Tracking Tensioning The conveyor may slightly stretch with continued use and will eventually need to be tensioned. This is most obvious if the conveyor starts slipping on the rollers. When you tension the conveyor, focus on turning the adjustment bolts in even increments.
Page 37
W1772/W1773 37" Drum Sander Tracking If the conveyor tracks to either side, then the tracking must be corrected or the conveyor will load up to one side and could rip or tear and have to be replaced. Replacing a damaged conveyor is a big job. Always be careful to make sure that the belt does not travel too far to one side or the other.
W1772/W1773 37" Drum Sander Drum.Adjustments There are three adjustments for the sanding drums: 1) the drums must be perpendicular to the feed direction (par- allel with the conveyor roller, Figure.49); 2) the drums must be parallel to the top of the conveyor belt (Figure.

W1772/W1773 37" Drum Sander Pressure.Roller.Height The pressure rollers are factory set at 0.039"–0.078" below the bottom of the rear sanding drum and are fully adjust- able either up/down with the lock nuts shown in Figure.59. Proper pressure on the workpiece helps avoid kickback and keeps the workpiece from slipping.
W1772/W1773 37" Drum Sander Scale.Pointer.Calibration For the scale pointer to be accurate, it must be calibrat- We recommend calibrating your scale pointer any time you adjust the drum heights or table lift screws. To.calibrate.the.scale.pointer,.do.these.steps: 1. Sand a workpiece with the drum sander and measure the thickness of the sanded workpiece.
W1772/W1773 37" Drum Sander Table.Lift.Scews The table lift screws are connected by a chain and driv- en by the table elevation handwheel. When the chain is removed from a sprocket on one of the lift screws, that lift screw can adjust that portion of the table up/down independently to assist in setting the table parallel to the drums.
