Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The
exclamation point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk.
Refer back to these warnings. Additional, product-specific warnings may be found throughout the body of this manual
where applicable.
WARNING
DUST AND DEBRIS HAZARD
Use of this equipment to grind concrete and other paving materials can result in the release of potentially
harmful dust or chemicals from the materials.
• For use only by sophisticated users familiar with applicable governmental safety and industrial
hygiene regulations.
• Use equipment only in a well-ventilated area.
• Wear a properly fit-tested and government approved respirator suitable for the dust conditions.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not operate the unit when fatigued or under the influence of drugs or alcohol.
• Do not leave the work area while equipment is energized. Turn off all equipment when equipment is
not in use.
• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manufacturer’s replacement parts only.
• Do not alter or modify equipment.
• Use equipment only for its intended purpose. Call your distributor for information.
• Keep children and animals away from work area.
• Comply with all applicable safety regulations.
• Maintain a safe operating distance from other people in the work area.
• Avoid any pipes, columns, openings, or any other objects protruding from work surface.
MOVING VEHICLE HAZARD
Careless and reckless behavior causes accidents. Falling from vehicle, running into people or object, or
being struck by other vehicles may result in serious injury or death.
• Do not step on forward/reverse pedals.
• Make turns slowly. Do not make turns greater than 45°.
• Loss of traction may occur going downhill. Do not operate on slopes greater than 15°.
• Do not carry passengers.
• Do not tow.
• Use with line striping equipment only.
• Use appropriate traffic control in all traffic areas. Refer to Manual on Uniform Traffic Control Devices
(MUTCD), U.S. Department of Transportation, Federal Highway Administration or local highway and

270 and 390 models are designed for “forward cut”
grinding (the drum rotates in the same direction that it
travels). 480 models are design for “reverse (up cut)”
grinding (the drum rotates in the opposite direction that
it travels).
