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.
V-BELT
Visually examine the V-belt (Figure 47) 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.
