PRO SERIES WALK-BEHIND TROWELS • OPERATION MANUAL — REV. #0 (9/21/17) — PAGE 43
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
NEVER 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
NEVER attempt to service a hot engine.
ALWAYS allow the engine to cool before
servicing.
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, any oil or fuel
leakage, or loose fasteners.
Air Cleaner
The engine air cleaner is equipped with a replaceable,
high-density, paper element. Refer to Figure 60 for air
cleaner maintenance.
Figure 60. Air Cleaner Maintenance
1. Remove the air cleaner cover and foam filter element.
2. Tap the paper filter element several times on a hard
surface to remove dirt, or blow compressed air, not
exceeding 30 lb/in² (207 kPa, 2.1 kgf/cm²), through
the filter element from the inside out.
NEVER 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.
