Checking And Cleaning Bonnet Screen And Air Intake Area To Prevent Overheating - Kubota ZG327A Operator's Manual

A Fuel blend differs from season to season for the best
seasonal engine performance. To prevent engine
performance troubles such as vapor lock or hard
starting, use fuel within the season in which the fuel is
purchased.
A Infrequent use of the engine during a season can
make fuel stale in the fuel tank of the machine. Stale
fuel condition can cause engine performance troubles
by varnish and plugged carburetor components.
A Seal the fuel storage container tightly and store it out
of sunlight and heat to prevent fuel degradation.
A Condensation in the fuel tank may occur because of
various operating or environmental conditions. To
reduce condensation and avoid affecting machine
operation, fill the fuel tank at the end of daily
operations.
A Do not use old fuel.
[Use of alcohol mixed gasoline (Gasohol)]
Use "gasohol" only when the ethanol additive is less than
10% of the fuel. The use of methanol additive is not
recommended. For the best results, use unleaded fuel
with a minimum of 87 octane.

BChecking and Cleaning Bonnet Screen
and Air Intake Area to Prevent
Overheating
To avoid serious injury or death:
A Engine components can get extremely hot from
operation. To prevent severe burns, do not
touch these areas while the engine is running,
or immediately after it is turned off.
Never operate the engine without heat shields
or guards.
To avoid personal injury:
A Be sure to stop the engine and remove the key
before cleaning.
A The bonnet screen and air intake area must be clear
of debris to prevent the engine from overheating.
Daily or after every 5 hours of operation, check to be sure
the air intake screen and the air intake area are clean.
Dirt or chaff around the air intake screen and air intake
area or the engine cooling area decrease cooling
performance.
1. Remove all foreign materials from the bonnet screen.
2. Open the hood.
3. Remove the dust and all foreign materials from the air
intake area between the transmission and the engine
dust cover.
4. Clean the engine shroud panel as necessary. For this,
refer to "EVERY 100 HOURS" in "MAINTENANCE"
section.
5. Each time the bonnet screen is covered with grass and
foreign materials during operation, rub it off the screen
with hand. Check the air intake area from time to time
if grass accumulates.
