perform this operation.

1. Inspect the fuel filter water separator daily. If the fuel
filter/water separator (Figure 49) has collected a
significant amount of water and sediment at the bottom
of the cup, it should be drained off.
Figure 49. Fuel Water Separator
2. To remove water and sediment from the cup, place
any fuel valves to the OFF position and unscrew the
cup from the base.
3. Pour the contents of the cup into a safety container.
Rinse cup with a mild detergent and reattach cup to

300 hours.

Oil And Fuel Lines
1. Check the oil and fuel lines and connections regularly
for leaks or damage. Repair or replace as necessary.
2. Replace the oil and fuel lines every two years to
maintain the line's performance and flexibility.
Visually examine the V-belt (Figure 51) and determine if it
is full of tiny cracks, frayed, has pieces of rubber missing,
is peeling or otherwise damaged.
Also, examine the belt and determine if it is oil soaked or
"glazed " (hard shiny appearance on the sides of the belt).
Either of these two conditions can cause the belt to run hot,
which can weaken it and increase the danger of it breaking.
If the V-belt exhibits any of the above wear conditions
replace the V-belt immediately.
