radiator, oil cooler, additional transmission
cooler and air conditioner condenser
greatly reduce their cooling efficiency. Use
compressed air, water and steam to clean
fins on radiator, oil cooler, and
transmission cooler.

site, clean fins every 50 hours.
On other work sites, clean fins
every 500 hours.
