Safety
Oliver Machinery has made every attempt to provide a safe, reliable, easy-to-use piece of machinery.
Safety, however, is ultimately depending on the individual machine operator. Before operating this
machine, please become familiar with the following safety labels and guidelines.
DANGER
This indicates an imminently hazardous situation which, if not avoided, WILL cause
death or serious injury.
WARNING
This means if the warning is not taken seriously, it CAN cause death or serious injury.
CAUTION
This means if the precaution is not taken, it MAY cause minor or moderate injury.
IMPORTANT
This is a tip for properly operating the machine to avoid machine damage.
General Safety Guidelines
1. FAMILIARIZE yourself with all safety instructions found in this manual. Know the limitations and
hazards associated with this machine. Do not operate/service this machine until you are properly
trained.
2. ELECTRICAL GROUNDING, when done properly, reduces the risk of electrocution, shocks, and fire.
Make certain that the machine frame is electrically grounded and that a ground lead is included in the
incoming electrical service. In cases where a cord and a plug are used, make certain that the grounding
plug connects to a suitable ground. Follow the grounding procedure indicated in the electrical code
of your area.
3. DISCONNECT the machine from power before performing any service, maintenance, adjustments, or
changing cutters. A machine under repair should be RED TAGGED to show it should not be used until
the maintenance is complete.
4. EYE PROTECTION: Always wear an approved safety face shield, goggles, or glasses that comply with
ANSI Z87.1 and CSA Z94.3 standards. Common eyeglasses are not safety glasses and may not provide
adequate protection.
5. EAR PROTECTION: Use hearing protective devices where the noise exceeds the level of exposure
allowed in Section 1910.95 of the OSHA Regulations. When in doubt, use it.
6. OTHER PERSONAL PROTECTION: Before the operation, remove tie, rings, watch, and other jewelry.
Roll up sleeves above elbows. Remove all loose outer clothing and confine long hair. Protective
footwear should be used. Do not wear gloves unless it is instructed to perform a particular step(s) in
the manual.
7. GUARDS: Keep machine guards in place for all applicable operations. If any guards are removed for
maintenance, DO NOT OPERATE the machine until all guards are reinstalled. Check clearance between
the guards and the cutter before starting the machine.

10 | Page Oliver Machinery 6320 Sander
8. WORKPLACE SAFETY: Keep the floor around the machine clean. Scrap material, sawdust, oil, and
other liquids increase the risk of tripping or slipping. Be sure to clean up the table before starting the
machine. Make certain the work area is well-lighted and that a proper exhaust system is used to
minimize dust. Use anti-skid floor strips on the floor area where the operator normally stands and
mark off the machine work area. Provide adequate workspace around the machine.
9. ACCESS CONTROL should be enforced so only trained personnel can access the work area and operate
the machine. Use a childproof power switch when applicable.
10. STAY ALERT at all times. Do not operate this machine while under the influence of drugs/alcohol or
when not feeling well.
11. NEVER STAND ON THE MACHINE. This prevents injuries from tipping-related accidents and accidental
contact with cutters.
12. REPLACEMENT PARTS: Use only genuine Oliver Machinery replacement parts and accessories
recommended for this machine. Generic parts made by other manufacturers may create a safety
hazard and WILL void the factory warranty and other guarantees.
13. PROPER USE: Do not use this machine for anything other than its intended use. If used for other
purposes, Oliver Machinery disclaims any real or implied warranty and holds itself harmless for any
injury or damage which may result from that use.
