Servicing The Cooling System
Attention
Avoid damage to your engine!
Using incorrect coolant mixture and/or type can
cause engine damage. Use only a mixture of 50%
distilled water and 50% ethylene glycol antifreeze.
Recommended antifreeze: a low silicate, phos-
phate free antifreeze (ethylene glycol) containing
supplemental coolant additives (SCA’s) to inhibit
corrosion and rust.
Dye Color does not determine the antifreeze
properties; ethylene glycol antifreeze of different
colors can be mixed.
WARNING
Avoid Personal Injury!
If the unit has been running, the radiator and radia-
tor coolant will be hot and can burn skin! Built-up
pressure in the radiator can cause an explosive
release of coolant if the radiator cap is removed:
• Shut off engine and allow to cool.
• Do not remove the radiator cap unless the
radiator and engine are cool enough to touch
with bare hands.
• Slowly loosen cap to the first stop to release
all the pressure before removing completely.
WARNING
Avoid Personal Injury!
Wear personal protective equipment to protect
eyes and hands when opening radiator cap to
protect against the pressure in the radiator.
If coolant is spilled on skin or clothing, change
clothing and wash affected skin immediately.
CAUTION
Coolant is poisonous to humans and animals and
is hazardous to the environment. Drain coolant into
an approved container. Dispose of used coolant in
accordance with local laws.
Checking The Cooling System
1. Park the power unit on a level surface.
2. Engage the parking brake and shut off the engine.
3. Remove the key from the ignition switch and
allow the engine to cool.
4. Open the engine hood to access the engine
compartment.
5. Check the coolant level in the coolant recovery
tank (A). When cold, the coolant recovery tank
should be approximately half full of coolant.
6.
A
B
If the coolant level is low, add coolant to the tank
and reinstall the cap.
7. If the coolant recovery tank is empty, slowly
open the radiator cap (B) to the first stop to allow
any pressure to release. Press down on the cap
slightly and continue to turn counterclockwise to
remove the cap from the radiator.
8. Check to ensure the coolant level is up to the
bottom of the filler neck.
9. If the coolant level is low, add coolant to the radi-
ator until it reaches the bottom of the filler neck.
10. Install the radiator cap.
11. Inspect the radiator hoses and clamps for leaks
and deterioration. Replace as necessary.
12. Close the engine hood.
