displacement of the cord and evidence of fluid
contamination.
The belt must be replaced if the following conditions
are present.
• The belt has a crack in more than one rib.
• More than one section of the belt is displaced in
one rib of a maximum length of 50.8 mm (2 inch).

NOTICE
Care must be taken to ensure that fluids are con-
tained during performance of inspection, mainte-
nance, testing, adjusting and repair of the product. Be
prepared to collect the fluid with suitable containers
before opening any compartment or disassembling
any component containing fluids.
Dispose of all fluids according to Local regulations
and mandates.
NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
Clean the cooling system and flush the cooling
system before the recommended maintenance
interval if the following conditions exist:
• The engine overheats frequently.
• Foaming of the coolant is observed.
• The oil has entered the cooling system and the
coolant is contaminated.
• The fuel has entered the cooling system and the
coolant is contaminated.
Note:
When the cooling system is cleaned, only
clean water is needed.
