LEACH HYDRAULIC FLUID RECOMMENDATION
All Leach hydraulic systems are factory filled with a high quality anti-wear htdraulic fluid meeting an ISO 32
specification. On units put into service where there are high ambient temperatures or sustained high duty cycles,
it may be desirable to change the fluid to an ISO 46 specification (higher viscosity). In colder climates or light duty,
an ISO 22 might be more appropriate. The International Standards Orginization assigns specification numbers so
that a consumer receives the same product from various suppliers.

Do not use engine oil, automatic transmission fluid (ATF) or add diesel
fuel or kerosene to the hydraulic fluid. Service life of all hydraulic system
components may be adversely affected.
HYDRAULIC FLUID
To serve its purpose and give long and satisfactory service, hydraulic fluid must possess desirable physical and
chemical characteristics. Stability over a wide range of trmperatures and under agitation is very important.
Premium hydraulic fluids should be used in Leach hydraulic systems. In addition to the above characteristics
selected additives should be incorporated to provide additional resistance to wear, corrosion, oxidation, decom-
position and foaming. All additive blending should be done by the lubricant supplier so that they are compatible
with each other.
A reputable lubricant supplier backed by a reputable oil company is great assurance of obtaining high quality
products and generally speaking, higher quality is worth the higher initial cost.
