This guideline will describe the operation and safety principles required for cleaning hydraulic hoses and tubes, using the Caterpillar hose cleaning group.This guideline will also describe the cleaning procedures of hydraulic system lines and tubes following a catastrophic failure.This hose cleaner group is CE certified.The three basic components required are:
A specially designed pneumatic launcher, which provides the pressure energy to force the projectile through the fluid carrier.
The nozzles that allow the unit to be utilized on varying sizes and types of hose, tube, pipe, and coupling configurations.
The projectile, which cleans the inside surface of the hose, tube, or pipe.Note: Throughout this publication the word "hose" will be used to identify all types of fluid carriers pipe, tubing and hose.To provide cleaning, the projectile is launched through a fluid carrier by a compressed gas. This gas (air) is delivered from the launcher through the nozzle. As the projectile travels the length of the hose, a cleaning force is applied to the inside walls. This force is applied to the wall of the passage due
