OPERATOR/CREW MAINTENANCE INSTRUCTIONS
Section I. LUBRICATION
3-1. General
The electric motor powered pumps require no periodic lubrication.
3-2. Detailed Lubrication Information
The electric motor powered pumps have been pre- lubricated at the factory and require no specific lubrication. It
may be necessary to use a fine oil around the bearings supporting the shaft in certain areas of operation. The operator
should maintain a constant watch for lubrication failures.
Section II. PREVENTIVE MAINTENANCE CHECKS AND SERVICES
3-3. General
To insure that the pumping units are ready for operation at all times, they must be systematically inspected so that
defects may be discovered and corrected before they result in serious damage or failure. The necessary preventive
maintenance checks and services to be performed are listed in paragraph 3-4. Defects discovered during operation of
the unit will be noted for future correction, to be made as soon as operation has ceased. Stop the unit immediately if a
deficiency is discovered during operation which would damage the equipment if operation were continued. All
deficiencies and shortcomings will be recorded together with the corrective action taken on DA Form 2404 (Equipment
Inspection and Maintenance Worksheet) at the earliest opportunity.
