E. GENERAL COMMENTS
The following factors generally contribute to poor hydraulic operation and premature wear of equipment:
1. Contaminated hydraulic fluid due to overuse, overheating, or inadequate fluid filtration.
2. Unsuitable hydraulic fluid, especially in extreme climatic conditions.
3. Defective packing or seals in components of the hydraulic system.
4. Poor or incomplete hydraulic system training. Users must be fully qualified to operate the equipment, and
have complete understanding of the hydraulic system.
If your hydraulic troubleshooting procedures involve flow and pressure tests at the power unit, McCoy Completions & Drilling recom-
mends construction of a test rig that can easily be connected to the main suction and discharge ports of the power unit.
