INSPECTION AND MAINTENANCE
4.1
GENERAL MAINTENANCE RULES
1.
Proper maintenance of the HydraPak and related hydraulic equipment consists of adhering to all the guidelines given in
this chapter and in the Pre-Operative Checklist in the front of this manual. Proper maintenance is required to maintain
the system in good condition, which is defined as each part being free of damage or functional defects.
2.
Review and follow all the safety rules given in Chapter 1 before attempting any maintenance.
3.
Only authorized personnel should be allowed in the maintenance area. Authorized personnel are the trained people as
defined below and their supervision.
4.
Repairs must be made only by trained personnel. A trained person is one who has read and thoroughly understands this
instruction manual and related equipment manuals and, through training and experience, has shown knowledge
regarding the safe operational procedures.
5.
All authorized maintenance personnel must wear the appropriate personal protective equipment as defined by their
employer.
WARNING:
SHUT DOWN THE HYDRAPAK BEFORE DOING ANY MAINTENANCE OR REPAIRS.
PREVENT ACCIDENTAL STARTUP BY REMOVING THE SPARK PLUG WIRE AND
DISCONNECTING THE NEGATIVE WIRE FROM THE BATTERY TERMINAL.
WARNING:
DO NOT ADJUST OR REMOVE HYDRAULIC COMPONENTS, LINES, OR FITTINGS WHILE
THE HYDRAPAK IS RUNNING OR WHENEVER THE HYDRAULIC FLUID IS HOT.
WARNING:
LIQUID UNDER HIGH PRESSURE CAN PIERCE THE SKIN, CAUSING DEATH OR SERIOUS
INJURY. IN CASE OF INJURY, GET IMMEDIATE MEDICAL ATTENTION.
4.2
HYDRAULIC SYSTEM INSPECTION AND MAINTENANCE
1.
Check to see that the hydraulic fluid is clean, and change oil and filter at recommended intervals to extend the life of
the HydraPak. Refer to the maintenance summary in Section 4.5.
2.
Clean debris from heat exchanger daily.
3.
Before making any hydraulic connections, inspect all hydraulic lines, fittings and hoses for leaks and risks of rupture as
follows:
a.
Inspect each hydraulic line, fitting, and hose for breaks, cracks, worn spots, bulges, chemical attack, kinks or any
other damage. Never try to stop any detected leak with any body parts. Do not put your face close to suspected
leaks. Hold a piece of cardboard close to suspected leaks and then inspect the cardboard for signs of hydraulic oil.
b.
Replace a damaged line, fitting or hose immediately. Never repair the part.
4.
The HydraPak uses flush-face quick-release couplings that are durable and easy to clean. Wipe the mating surfaces of
the couplings with a clean rag prior to making connection. They are always fitted such that the male coupling gives oil
and the female coupling receives oil.
