G0486/G0487 Wide Belt Sander -21- T able Mo v emen t The table height can be adjusted manually or with the digital key pad and motor (see Figure 16 ). Manual Table Movement: Turn the handwheel located under the front of the infeed table for manual table positioning.
-22- G0486/G0487 Wide Belt Sander Am p Dra w M eter The amperage draw meter ( Figure 18 ) is located above the control panel. Use the meter to monitor the amperage draw on the machine while per- forming sanding operati ons. As a general rule, always start with a small load and work your way up.
G0486/G0487 Wide Belt Sander -23- Sand in g W or k piece Typically, no more than 0.5mm (approx. 1 ⁄ 64 ") of material is removed during each pass. Attempts to remove too much material can cause jamming, wood burning, rapid sandpaper wear or tearing, poor finish, short motor life, and belt slippage.
-24- G0486/G0487 Wide Belt Sander Figure 21. Sanding belt cleaning pad. H2845—Cleaning Pads Cleaning pads are the perfect accessory for wide belt sanders. Simply set the conveyor table to height and feed the pad through to “unload” a dirty sanding belt.
G0486/G0487 Wide Belt Sander -25- Disconnect power to the machine when perform - ing maintenance, assem - bly or adjustments. Failure to do this may result in serious person - al injury.

-30- G0486/G0487 Wide Belt Sander 5. Tighten the lock nut ( Figure 28 ) to secure the airflow adjustment knob. 6. Restrict the airflow across the air fork gap with a scrap piece of wood. You should notice the roller pivot to the right. When the stick is removed, the roller should pivot back to the left.
G0486/G0487 Wide Belt Sander -31- NOTICE The table has been adjusted at the fac- tory and should require no further attention. However, we recommend verifying that it is parallel with the sanding roller. The oscillation speed of the sanding belt is adjustable.
