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.
WARNING
Avoid Personal Injury!
Wear personal protective equipment to protect eyes
and hands when opening the radiator cap to protect
against the pressure in the radiator.
If coolant is spilled on skin or clothing, change
clothing and wash a󰀨ected skin immediately.
WARNING
Avoid Personal Injury!
If the unit has been running, the radiator and radiator
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 o󰀨 the 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 the cap to the rst stop to release
all of the pressure before removing completely.
1.
Attention
Avoid damage to your engine!
Using the 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, phosphate
free antifreeze (ethylene glycol) containing supple-
mental coolant additives (SCA’s) to inhibit corrosion
and rust.
Dye Color does not determine the antifreeze proper-
ties: ethylene glycol antifreeze of di󰀨erent colors can
be mixed.
Park the power unit on a level surface.
2. Engage the parking brake and shut o󰀨 the
engine.
3. Remove the key from the ignition switch and
allow the engine to cool.
4. Open the radiator access panel (A).
5. Slowly open the radiator cap (B) to the rst stop
to allow the pressure to release.

Before making repairs or adjustments set the
parking brake, turn o󰀨 the engine, and remove
the ignition key.
Always disconnect the negative battery cable
from the battery when working with electrical
components. Always work in a manner that does
not put safety at risk!

6. Place a drain pan under the radiator drain port
(C) located underneath the left side of radiator.
7.
CC
Install a 7/16” (11 mm) ID hose onto the drain
port and route the hose down to the drain pan.
8. Turn the radiator drain valve counterclockwise to
open and drain the coolant into the drain pan.
9. When all of the coolant has drained into the pan,
close the radiator drain valve. Leave the hose in
place.
10. Add one can of radiator ush to the radiator and
ll the radiator with clean water.
11. Install the radiator cap, start the engine , and run
the engine until the engine reaches operating
temperature (160-180° F) (71-82° C).
12. Shut o󰀨 the engine and remove the key from the
ignition switch.
13.
WARNING
Hot coolant can cause severe burns. Allow the
temperature of the radiator to drop from hot to warm
before draining the coolant.
Carefully drain the cooling system while the
coolant is still warm.
14. Allow the engine and radiator to cool completely.
15.
CAUTION
Allow the engine and radiator to cool completely.
Engine damage could occur if cold water is added to
a hot engine.
Add clean water to the radiator and allow the
water to run through the system. Add more
water as needed, until the water is owing from
the drain valve clear and free of sediment.
16. After the water has drained completely, close the
radiator drain valve and remove the drain hose.
17.
Attention
NOTE: residual water may be present in the
engine. Adjust the coolant mixture to achieve a
50/50 ratio.
Slowly add the proper coolant (refer to the
Engine Owner’s Manual for the correct type of
coolant) to the radiator until the level reaches
the bottom of the ller neck.
18. Install the radiator cap, start the engine, and run
until the engine reaches operating temperature
(160-180° F) (71-82° C).
19. Shut off the engine and allow the engine to cool.
20. Recheck the coolant level when the engine is
cold. Add additional coolant if necessary.
21. Close and secure the radiator access panel.
