HOSE INSPECTION
Inspect hoses for leaks regularly to ensure
efficient, economical and safe operation of the
engine and related equipment. Carefully inspect
all fittings, clamps and ties. To prevent chafing,
make sure hoses are not touching shafts,
couplings, heated surfaces, sharp edges or other
parts. Since hose clamps and ties can vibrate
loose or fail over time, frequently inspect and
tighten or replace as necessary.
Correct leaking hoses immediately. Failure to
correct leaks can cause severe damage to the
equipment, as well as increase operating costs
due to lost fluids. Treat fuel and oil leaks as an
immediate fire hazard.
WARNING
Personal injury and property damage may result
from fire caused by leaking flammable fluids.
Hose Service Life
Hoses have a limited service life. Thoroughly
inspect hoses annually. Look for surface damage
or indications of twisted, worn, crimped, cracked
or leaking lines. Replace damaged hoses
immediately.
Hoses should be replaced during major overhaul
or after a maximum of seven service years. Be
certain replacement hoses are matching the
original equipment manufacturer's specifications.
