Preventative Maintenance, continued;
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.
3. 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
cooling and WILL eventually cause serious damage to your engine.
The debris accumulating on the radiator can be lessened by lower-
ing 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 cool
-
ant 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.
4. Engine Air Cleaner:
Due to the large amounts of dust generated in collec-
tion leaves, it is critical to your engine's life that the pre-cleaner 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
5. 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.
