G9983 15" Open-End Wide-Belt Sander -23-
General
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.
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.
Disconnect power to the
machine when perform-
ing any maintenance or
assembly. Failure to do
this may result in serious
personal injury.
SECTION 7: MAINTENANCE
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 again—this 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.
