Cleaning the Chassis

Service Interval: Every 100 hours—Check for dirt
build-up in the chassis.
Over time, the chassis under the engine collects dirt
and debris that must be removed. Using a flashlight,
open the hood and inspect the area under the engine on
a regular basis. When the debris is 1 to 2 inches deep,
complete the following procedure (refer to Figure 57
throughout this procedure):

from spilling the gasoline.
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and
others and can damage property.
• Remove the fuel tank outdoors in an open
area. Wipe up any gasoline that spills.
• Do not remove the fuel tank near an open
flame or where gasoline fumes may be
ignited by a spark.
• Do not smoke while handling the fuel tank.
14. Remove any large deposits of debris.
15. Wash out the chassis with water until the water
running out the back of the unit is clear.
Important: Take care not to get water into the
engine or electrical components.
16. Slide the fuel tank part way into the chassis
(Figure 57).
17. Connect the fuel line and remove the clamp.
18. Secure the tank cap.
19. On the right side of the tank, connect the orange
wire to the center post and the black wire to the
outside post (Figure 58).
