Cooling System
1. If you must remove the cap for the radiator follow the instructions below and then carefully replace the cap
securely.
2. If a coolant leak occurs immediately consult manufacturer.
3. DO NOT overfill the safety relief tank above the line marked “FULL”.
Coolant System Guidelines
1. Always wear appropriate PPE such as rubber gloves, face shield, protective apron, etc., when handling coolant or
refrigerant.
2. In any case of ingestion of coolant/refrigerant force regurgitation and immediately seek medical attention.
3. If contact with exposed skin or clothing occurs wash with water immediately.
4. DO NOT mix different types of coolant. Use only manufacturer approved items.
5. Keep coolant away from flames and small children.
6. Dispose of used coolant in accordance with local, state, and federal guidelines.
7. To drain coolant or refrigerant always be sure to open both drain valves and open the cooler cap. If you do not
open the cap coolant will not drain correctly.
8. Remove the overflow hose from the radiator pressure cap to drain the expansion tank.
Coolant/Refrigerant Overheating
If the alarm light turns on due to coolant/refrigerant temperature or because coolant/refrigerant steam begins splashing
from the overflow pipe. Turn off the load and operate the engine at idle for a minimum of five minutes to allow it too
gradually cool. Then, stop the engine and inspect the following:
1. Leaks in the coolant system.
2. Pinched lines or obstructions to the coolant system itself.
3. That radiator fins and cooling fan blades are free from dust build up
4. Verify the tightness of the fan belt
Coolant System Cleaning
1. DO NOT clean the cooler with any hardened tools such as screwdrivers, paint scrapers, etc. These tools can
damage the fins and lead to leakage.
2. Remove dust and build up by washing it with running water.
