1.7.2 Cummins B3.3QSB, Fuel Filter, Lubricity
1.
The fuel filter must be changed every 250 hours of operation or 6 months
after the date of installation, whichever comes first. The filter needs to be
changed to insure a continuous supply of additive to the fuel pump.
2.
The filter head itself has a special threaded spud to insure that the correct
filter with lubricity additive is used. Failure to change the fuel filter every
250 hours will result in damage to the fuel pump.
3.
The filter must be changed every six months whether the machine is in
operation or not due to static release of the additive into the fuel when the
engine is not in operation. Failure to change the filter a minimum of every
six months will result in damage to the fuel pump.
4.
Seasonal applications should consider storing the filter off engine, insuring
that ALL fuel is drained from the filter.

1.8 HYDRAULIC SYSTEM
1.8.1 Hydraulic System Safety
To minimize risk of serious injury or death, follow these
hydraulic servicing precautions:
• Follow all necessary lockout/tagout procedures.
• Hydraulic systems have residual, stored pressure. Relieve all pressure from
the hydraulic system before servicing.
• Allow fluid to cool before working on system.
• Hydraulic fluid escaping under pressure can have sufficient force to enter
eyes and penetrate skin. If fluid gets in eyes or skin, flush with large
quantities of water and seek medical attention.
• Wear eye protection when servicing hydraulic components or systems.
