PREPARATION

PLANNING YOUR WORK

Planning your work before operation will help to save time and minimize setups. Group your 
workpiece by thickness and grit requirements. Work through each required sanding grit from the 
thickest to the thinnest material. Then, change to a finer grit sandpaper and work through the 
process again.

      WARNING:

 To avoid injury from accidental startups, always ensure that the tool is switched 

OFF and unplugged from the power supply before making adjustments.

INTRODUCTION

The drum sander is a machine designed to sand wooden workpieces to a desired thickness and 
smoothness. Before adjusting and operating the machine, it is important to know that drum sanding 
is different from thickness planing. Drum sanding can only remove material in increments of 1/32 
inch (0.8mm) or less, depending on the sanding grit, material hardness, sanding width, etc. The drum 
sander is not suitable for quick bulk material removal. Forcing your drum sander to remove too much 
material too fast will cause damage to your machine and the workpiece. 

WORKPIECE INSPECTION

This drum sander is intended for sanding natural and man-made wood materials. This machine 
cannot sand other materials such as metal, glass, stone, tile, etc. Make sure to inspect all workpieces 
before operation and refer to the list below for materials that you should avoid or take extra care with.

FOREIGN OBJECTS. Foreign objects such as nails, staples, dirt, rocks, etc. are often embedded in wood. The 

objects may cause kickback that can hit the operator and damage the machine. Remove those foreign objects 

before operation. 

LARGE OR LOOSE KNOTS. Choose workpieces that do not have large or loose knots. Large knots may cause 

kickback and damage the machine. Loose knots in stock can become dislodged during sanding operations. 

WOOD SPECIES WITH TOXIC PROPERTIES. Wood species such as the rosewood family (e.g. cocobolo) have toxic 

properties that may result in allergic reactions. Even with dust control, you may inhale small airborne particles and 

possibly suffer an allergic reaction.

HIGHLY RESINOUS SPECIES. Highly resinous species tend to quickly clog or load up sandpaper easily. This 

includes some common pine species. It is almost impossible to clear the sandpaper of the pitch and sawdust from 

those species of wood. Avoid sanding those wood species or make sure to replace sandpaper often.

WET OR GREEN STOCK. Wood stock with a moisture content over 20% causes excessive wear on the sandpaper 

and motors as you’re sanding. This may increase the risk of kickback and result in a poor surface finish. Use stock 

with moisture content below 20%.

EXCESSIVE WARPING. Do not sand workpieces with excessive warping or twisting as they are unpredictable and 

difficult to hold stable. DO NOT sand workpieces with excessive warping.
