Figure 2: Belt and Disc Sander Features

(Left Side View)

The sander has both a sanding belt and a sanding	7
disc for use on a variety of work pieces and materi-
als.

The platen housing for the belt sander can be positioned vertically or horizontally. When in the vertical position, the drum at the upper end of the platen housing can be used for contouring. A tracking adjustment mechanism for the sanding belt is provided at the upper end of the platen housing.

The platen housing has a lever that is used to apply tension to the sanding belt. The sanding belt is easily replaced by releasing the tension lever, removing a sanding shroud and dust collection duct at the bottom of the platen housing, and slipping the belt from the belt sander drums. Installation is the reverse of the removal steps.

The disc sander consists of an aluminum disc onto which is installed an adhesive-backed sanding and other abrasive discs. The disc is contained within a ducted shroud.

The sanding disc can be replaced by removing the table and a cover over the lower portion of the disc. If desired, the aluminum disc can be removed from its drive shaft to ease replacement of the sanding disc.

The drive motor for the belt and disc sander is attached to the underside of the machine base. An ON/OFF switch is mounted on the machine base on the side opposite the disc sander. Electrical wiring for the motor enters the machine base below the ON/ OFF switch and is routed to the switch and motor inside the machine base.

The belt and disc sander is driven by V-belts connected to the drive motor. A pulley on the motor shaft drives a V-belt that drives a dual-groove pulley on an idler shaft. A second V-belt is installed in the second groove of the dual-groove pulley and connects to a pulley on belt sander drive shaft.

The aluminum sanding disc is driven off the end of the idler shaft. A shaft connected to the second V- belt pulley drives the belt sander drive drum.

The belt and disc sander is mounted on a stand that can be secured to the floor to stabilize the machine. The stand has a door for access to the fasteners for the machine base.

Installation and Setup

Mounting

It is recommended that the belt and disc sander be secured to the floor for safe operation. The machine stand has mounting holes in a flange on the inside of stand enclosure. The stand can be secured to the floor using these mounting holes.

Electrical Connection

Refer to the Wiring Data section for wiring information. Electrical power should be connected by a qualified electrician. Observe local electrical codes when connecting and grounding the machine.
