CLEANING WITH COMPRESSED AIR
Directing compressed air, pressurized water, or steam directly at your body, or using these and causing dust to fly may cause
personal injury. Always wear protective glasses, anti-dust mask, and other protective equipment.
When carrying out cleaning, always stop the engine and check that the fan is not rotating. If you touch the fan when it is
rotating, it will cause serious personal injury.
NOTICE
When using compressed air for cleaning, blow it keeping some distance to avoid damaging the fins. Damage on the fins can cause
water leakage and overheating. In a dusty job site, check the fins every day, regardless of the maintenance interval.
