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 radia-
tor is not cleaned properly it WILL cause improper cooling and WILL eventu-
ally 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
specics on coolant mixture ratios and conditioners. The radiator should be
inspected and cleaned with compressed air everyday at the very least.
NEVER attempt to clean or inspect the radiator with the engine running 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.
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 lter 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 lter should be checked daily and should be replaced at the rst sign of
it being dirty. DO NOT attempt to clean the air lter, replace the dirty air lter.
It is a good idea to clean out the air lter 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 ination 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.
