Normal operations of hydraulic systems are at temperatures at

and below levels to cause discomfort on unprotected skin.There are conditions at which the fluid and surfaces will be

above 138F that will cause burns to unprotected skin. Extreme caution and safetyclothing should be used while in contact with these surfaces.

The majority of hydraulic systems use an electric motor as theprime mover. This system may also include switches, solenoidsand/or motor starters running at high voltages. These high

voltages are at lethal levels. All electrical power must be disconnected anytimemaintenance is performed on this unit. Only qualified electricians should maintain theelectrical system of this unit.

This unit must not be exposed to an explosive atmosphere.

Hydraulic fluid is flammable. Other debris in this area may beflammable as well. There should be no smoking or other formsof ignition in and around the location of this unit.

Working Fluid

The correct fluid is critical to the proper operation of any fluid power system. This

unit is only compatible with standard mineral based hydraulic fluid. The fluid mustalso be compatible with the fluid in the main hydraulic system or the fluid in thehydraulic actuator on the Tyco Knife Gate Valve. Poor performance may be causedby improper fluid type. Below are some suggested fluid manufacturers:

Ambient Temperature Range ISO Grade Hydraulic Fluid Manufacturers Examples

-20F* to 80F 32Chevron Rykon 32Shell Tellus Premium 32Mobil DTE 24

10F to 100F 46Chevron Rykon 46Shell Tellus Premium 46Mobil DTE 25

40F to 120F 68Chevron Rykon 68Shell Tellus Premium 68Mobil DTE 26

All these fluids are compatible with each other. Phosphate Ester or water glycol fluidsare not acceptable for this power unit. Synthetic oils are acceptable as long as they arecompatible with the above mentioned brands of oil.
