1. Routine Radiator Maintenance tips
• Regularly check radiator hoses. Inspect clamps and make sure they are secure.
• If hoses become deformed, develop bulges, hardening or cracking is visible, they need to be
changed immediately!
• Inspect and clean the cooling fins on the radiator regularly, use compressed air to blow out
excess dust and dirt. Important! Blow compressed air from the inside out. Debris can build over
time and affect the cooling system.
2. Routine Belt inspection tips
Adjust and replace timing belt and water pump belt as needed. Inspect them regularly for cracking
or missing pieces of rubber. Timing belt needs replacement every 1,000 hours of use! Water pump
belt is extremely important. It drives the water pump that cools the engine and entire system.
Note: Listen for sounds coming from the belts. If you hear the belts squealing when the generator
starts up, this is a sign that the belts are loose or worn and the system will run hot! If belts show
signs of cracks or pieces of belt are missing, contact service provider.
Important! To check to see if the belt is too tight make sure the main power
switch is in the off position.
Perform the following inspections and adjust or replace belt as needed.
Deflection check of the belt:
7~10mm (0.28-0.35in) ∕ 100N {10.01kgf (22.1 lbs.)
Adjust the deflected belt:
• Stop the engine.
• Use thumb to press on the belt between pulley wheels.
• If the tightness is not correct, adjust it by relaxing the tension wheel to the acceptable degree.
• Replace the water pump belt when it is cracked, missing pieces of rubber or singes of considerable wear.
