Cooling System: Service; Air Cleaner Service - Vanguard CPW 125-4-S Series Operation And Maintenance Manual

Cooling System: Service

Coolant is toxic. Keep away from children and pets.
To service the cooling system (Check, Drain, Flush), follow the instructions outlined in the Cummins® Operation and
Maintenance Manual QSB4.5 and QSB6.7 Engine (Bulletin 4021531); see the appendices at the end of the Weld-Deck
Operation and Maintenance Manual, Weld-Deck welding package CPW 125-4-S2-4.

Air Cleaner Service

Never operate the engine without the complete air cleaner assembly installed. Intake air must be filtered to prevent dirt and
debris from entering the engine and causing premature wear or engine damage.
Figure 78: Monitor genset air filter
The red flag in the Indicator window gradually rises as the filter cartridge loads with dirt. After changing or replacing the
cartridge, reset the indicator by pushing its reset button.
For detailed air cleaner service instructions, refer to the Air Cleaner Service manual in the appendices at the end of the Weld-
Deck Operation and Maintenance Manual, Weld-Deck welding package CPW 125-4-S2-4.
Note: Service the primary filter element only when the Air Cleaner Restriction indicator showing fully RED. Do not open
the filter compartment unless it is time for service. Opening the filter compartment can cause dirt to get into the clean side of
the filter housing.
Note: Extremely short air filter life can result if the precleaner system malfunctions. If air filter life is drastically reduced
from typical for the operating conditions, consult your Dealer.
Service the engine air filters with the engine stopped. Engine damage could result. Never operate the engine without the
complete air cleaner assembly installed. Intake air must be filtered to prevent dirt and debris from entering the engine and
causing premature wear or engine damage.
Note: Do not use the air filter for longer than one year.
