Inspection of Cooling System
Hoses
Check the cooling system hoses and fan belt for
any cracks or deterioration after every 100 hours of
operation. Check for loose hose connections. Replace
any damaged hoses and tighten any loose connections.
Replace a worn or damaged fan belt.
Changing the Engine Coolant
The engine coolant should be drained and replaced with
new coolant solution every 2 years or 500 hours.
Dilute the antifreeze with water at a 1 : 1 ratio to mix the
coolant solution (50% antifreeze : 50% water).
Change the engine coolant as follows:
1. Drain the coolant when the engine is cold.
2. Place the unit on a level surface and raise the hood.
3. Slide the overflow reservoir upward and off the
reservoir bracket to access the radiator drain plug.
4. Locate the radiator drain plug in the lower right rear
corner of the radiator.
5. Place a suitable container beneath the drain plug
and remove the cap from the overflow reservoir.
6. Turn the drain plug counterclockwise to re-move.
Allow as much of the old coolant as possible to drain
from the system.
