COOLING SYSTEM
Cleaning the Rotary Screen, Radiator, Hydraulic Oil Coolers
and Condenser Core
Inspect the cooling system daily.
The rotary screen is self-cleaning and gives
protection to the radiator, fuel/oil cooler and
condenser. In some conditions a layer of material
may build up on the screen. Periodic cleaning may be
required. With the engine stopped, lightly brush the
exterior of the screen to remove fine material.
Compressed air is recommended to remove material
from the screen, if necessary. Water may cause
plugging of screens and cores.
The radiator/cooler fins are designed to minimize
build up of material in the cooler core. Material will
normally deposit on the front face of the coolers.
Periodic cleaning may be required. With the engine
stopped, lightly brush the exterior of the coolers to
remove material. Compressed air can be used to
remove material from the coolers, if necessary.
IMPORTANT: Always wear face protection when
using compressed air.
