Section 9 - Maintenance
Page 27
Always clean the surrounding area before opening hydraulic systems.
Use only recommended lubricants. Improper lubricants or incompatible
lubricants may cause as much damage as no lubrication.
Watch for makeshift "fixes" which can jeopardize safety as well as lead
to more costly repair.
Inspection and maintenance should be performed by qualified personnel
familiar with the equipment.
