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, reduce 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
when 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 complies 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.
