MAINTENANCE
General maintenance practices are crucial to the
performance and longevity of your trowel. This equipment
requires routine cleaning, lubrication, and inspection of
components for wear or damage.
Refer to Table 6 and Table 7 to schedule engine and trowel
maintenance. The following maintenance procedures can
prevent serious trowel malfunction or damage.
DANGER
DO NOT
use gasoline or low flash
point solvents to clean the engine or
any of its components. The possibility
exists of
fire
or
explosion
which can
damage the equipment and cause
severe bodily harm
or even
DEATH
.
WARNING
Some maintenance operations may
require a running engine.
ALWAYS
make sure the maintenance area
is well ventilated. Gasoline engine
exhaust contains
poisonous carbon
monoxide gas
that can result in
unconsciousness
and/or
DEATH
when inhaled.
CAUTION
ALWAYS
allow the engine to cool before
servicing.
NEVER
attempt to service a
hot engine.
CAUTION
ALWAYS
disconnect the spark plug wire from the
spark plug and secure it
away
from the engine before
performing trowel maintenance or adjustments.
ENGINE MAINTENANCE
Inspect the engine daily for cleanliness, oil or fuel leakage,
and loose fasteners.
Air Cleaner
The engine air cleaner is equipped with a replaceable,
high-density, paper element. Refer to Figure 37 for air
cleaner maintenance.
Figure 37. Air Cleaner Maintenance
1. Remove the air cleaner cover and foam filter element.
2. To remove dirt, tap the paper filter element several
times on a hard surface or blow compressed air, not
exceeding 30 psi (207 kPa or 2.1 kgf/cm²), through the
filter element from the inside out.
DO NOT
brush off
dirt. Brushing will force dirt into the fibers. Replace the
paper filter element if it is excessively dirty.
CAUTION
ALWAYS
wear personal protective
equipment such as approved safety
glasses, face shields, dust masks, or
respirators when cleaning air filters with
compressed air.
