INTRODUCTION

This work package and referenced technical manual (TM 9-4940-468-13) for the Hydraulic System Test and Repair,

(HSTRU) provides all the required WARNINGs, CAUTIONs, NOTEs and procedures for the maintenance of hydraulic

hose assemblies.

Before attempting to disassemble, repair, or fabricate any hydraulic hose(s) utilizing the HSTRU, read and understand

all WARNINGs, CAUTIONs and NOTEs in this work package and in TM 9-4940-468-13.

WARNING

Do NOT remove or disconnect any hydraulic system line or fitting unless hydraulic system pressure

has been relieved. Hydraulic system pressure can be over 2500 psi (17,237 kPa), even with engine and

pump OFF. To relieve pressure, lower all hydraulic attachments to the ground and shut down engine.

Move control levers through all operating positions, then SLOWLY loosen hydraulic tank filler cap.

After maintenance, tighten all connections before applying pressure. Escaping hydraulic fluid under

pressure can penetrate the skin, causing serious injury or death.

At operating temperature hydraulic oil is hot. Allow hydraulic oil to cool before disconnecting any

hydraulics. Failure to do so could result in injury.
