FLYING SPARKS AND HOT METAL
Chipping and grinding cause flying metal. As welds cool, they can
throw off slag.
• Wear approved face shield or safety goggles. Side shields
recommended.
• Wear proper body protection to protect skin.
MOVING PARTS
Moving parts, such as fans, rotors, and belts can cut fingers and
hands and catch loose clothing.
• Keep all doors, panels, covers, and guards closed and
securely in place.
• Stop engine before installing or connecting unit.
• Have only qualified people remove guards or covers for
maintenance and troubleshooting as necessary.
• To prevent accidental starting during servicing, disconnect
negative (-) battery cable from battery.
• Keep hands, hair, loose clothing, and tools away from
moving parts.
• Reinstall panels or guards and close doors when servicing
is finished and before starting engine.
