Regular Maintenance

The engine coolant level and quality should be 
checked before each use, when the engine is cool 
and off.

 1.  Remove the radiator pressure cap (A, Figure 18) 

to check the fluid level.

 2.  Coolant level should be 1/2” (13mm) below the 

bottom of the filler tube.  If coolant level is low, 
add coolant until level is 1/2” (13mm) below the 
bottom of the filler tube.  Proper coolant mix is 
a 50/50 mixture of ethylene glycol and distilled 
water.  See engine owners manual for engine 
coolant specifications.

 3.  Check the coolant level in the radiator expansion 

tank (Figure 19).  If coolant level is low, remove 
the cap add coolant until level is at the “FULL” 
line.  Proper coolant mix is a 50/50 mixture of 
ethylene glycol and distilled water.  See engine 
owners manual for engine coolant specifications.

See engine owners manual for specific engine 
coolant procedures.  The drain valve is located at the 
base of the right-hand side of the radiator.

Clean the radiator, screen and oil cooler fins before 
each use, or as required (depending on conditions) to 
allow proper air-flow through radiator and hydraulic oil 
cooler.

 1.  Raise the seat plate.

 2.  Lift the radiator screen straight up to remove the 

screen.  Flush the screen with water or blow clean 
with air.  Flush the radiator core with water or blow 
clean with air.  See engine owners manual for 
proper radiator cleaning procedures.

• Do NOT touch hot radiator or open reservoir 
when engine is running.
• Stop and allow engine to cool before removing 
the radiator cap or the reservoir cap and before 
changing or adding coolant.

 3.  Clean all dirt, grass, and debris from the oil cooler 

fins.

 4.  Reinstall the radiator screen.  Make sure the 

screen is fully seated in the carrier.

 5.  Lower the seat plate.
