Preventative Maintenance, continued;
Engine Radiator:
The engine radiator on a leaf vacuum becomes
clogged with dust and debris frequently because of the nature of the
job. If the radiator is not cleaned properly it WILL cause improper cool -
ing and WILL eventually cause serious damage to your engine. The
debris accumulating on the radiator can be lessened by lowering the
RPM on the engine to a level just enough to vacuum the leaves. The
higher the RPM the more dust that is put into the air. Also, it may be
necessary to put mesh or tarps on the top of the leaf box container to
reduce the debris and dust. If this is done, make sure there is enough
air ventilation on the box so the box is not blown apart. Proper belt
condition and coolant mix-ratio, as well as coolant conditioners, are
all critical to proper engine cooling. See the engines owner's manual
for specifics on coolant mixture ratios and conditioners. The radiator
should be inspected and cleaned with compressed air everyday at the
very least.
Engine Air Cleaner: Due to the large amounts of dust generated in
collection leaves, it is critical to your engine's life that the pre-clean-
er and air filter be maintained properly. The pre-cleaner should be
cleaned at least daily of any debris that has accumulated. If conditions
warrant it should be cleaned more. The air filter should be checked
daily and should be replaced at the first sign of it being dirty. DO NOT
attempt to clean the air filter, replace the dirty air filter. It is a good idea
to clean out the air filter housing once a week to clean any dust debris
that may have accumulated.
Tires and Wheels: Tires and wheel lug nuts should be checked on a
daily basis. Tires should be checked for excessive wear and proper air
pressure. Check the side wall of the tire for proper inflation pressure.
Torque all 1/2" diameter lug nuts from 90 to 120 foot pounds. Torque all
5/8" diameter lug nuts from 175 to 225 foot pounds. Consult the axle
manufacturers owner's manual for more detailed information.
NEVER attempt to clean or inspect the radiator with the engine run-
ning or while the engine is HOT. Allow the engine to cool at least
one hour before mantaining the radiator. Check the engine owner's
manual for instructions. ALWAYS wear eye and hand protection
when working with the radiator.
