tion.
HOT COOLANT CAN BURN SKIN
•
Always be sure coolant is not hot before doing any
work on cooler parts.
ROTATING FAN BLADES ARE HAZARDOUS
• Do not put your hands near an operating fan.
• Keep all equipment safety guards, covers and devices in position
and in good repair.Keep hands, hair, clothing and tools away from
fans and all other moving parts when starting, operating or repair-
ing equipment.
• In some cases it may be necessary to remove safety guards to
perform required maintenance. Remove guards only when neces-
sary and replace them when the maintenance requiring their
removal is complete. Always use the greatest care when working
near moving parts.
