SECTION 7: MAINTENANCE

Disconnect power to the machine when perform- ing any maintenance or assembly. Failure to do this may result in serious personal injury.

General

Make a habit of inspecting your Model G9983 each time you use it. Failure to routinely inspect your wide-belt sander for damage and wear could result in unsatisfactory work results, premature component or machinery failure, or operator injury. We recommend you create a checklist for routine inspection and maintenance. Check for the following conditions and repair or replace when necessary.

•Loose mounting bolts.

•Worn or damaged sanding belt.

•Worn or damaged cords, plugs or switch.

•Damaged V-belt.

•Any other condition that could hamper the safe operation of this machine.

Cleaning Sanding Belts

You can greatly increase the lifespan of your sanding belts if you clean them often. As men- tioned on page 22, cleaning pads are the best way to do this.

Whenever sanding belts decrease in perfor- mance because of heavy loading, feed the clean- ing pad through the sander. Repeat this process until the sanding belts are clean againÑthis will ensure optimum performance.

Emptying Filters

There are two filters on the Model G9983. The first filter is located under the main regulator that houses the pressure gauge. The second filter, shown in Figure 19, is located near the oscillation controls. Since the eye fork configuration is prone to collecting sawdust, check and empty this filter often.

Lubrication

Roller bearing blocks must be lubricated every 20 hours of operation with high-quality, lithium based grease via grease fittings on top of each block.

Other moving parts, such as chains, should be lubricated periodically with a light machine oil. Do not use too much lubrication because excess can attract dirt and sawdust and will clog the chain mechanism.

Figure 19. Unscrew this filter to empty it.
