ATTACHMENTS AND OPTIONS
Every 500 Hours Maintenance
Clean Air Conditioner Condenser
If compressed air, high-pressure water, or steam hit your body directly, or they cause dirt or dust to be blown up, there is a hazard
of serious injury. Always use safety glasses, dust mask, or other protective equipment.
NOTICE
When using compressed air, keep the air nozzle at a distance to prevent damage to the fins. Especially for the aftercooler, blow
the air from 300 mm (11.8 in) or more, and at a 45 degree angle.
To prevent damage to the fins, apply compressed air from an appropriate distance. Damaged fins may cause water leakage or
overheating. On dusty sites, check the fins daily, regardless of the maintenance interval.
1. Blow off mud, dust or leaves clogging the condenser fins using
compressed air.
Steam or wter may be used instead of compressed air.
2. Check the rubber hose. Replace with a new one if the hose is
found to have cracks or to be hardened by aging.
Also, check hose clamps for looseness.
