Checking And Cleaning The Air Intake Screen; Checking The Tire Pressure; Inflation Pressure; Checking Transaxle Fluid Level - Kubota Z231BR-AU Operator's Manual

DAILY CHECK
avoid affecting the machine operation, fill the
fuel tank at the end of daily operations.
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 best results, use unleaded fuel
with a minimum of 87 octane.
3. Checking and cleaning the air
intake screen
WARNING
To avoid serious injury or death:
• Be sure to stop the engine and remove the key
before cleaning.
• Make sure that the engine is cool to the touch
before cleaning.
IMPORTANT :
• The air intake screen and air intake area must
be clear of debris to prevent the engine from
overheating.
Daily or after every 5 hours of operation, make sure the
air intake screen and the air intake area are clean.
Dirt or chaff around the air intake screen, air intake
area, or the engine cooling area decrease cooling
performance.
1. Check that the air intake screen is clear of grass
clippings and debris.
2. If the screen is dirty, clean it with a brush or cloth.
3. Remove the dust and all foreign material from the
engine plate.

4. Checking the tire pressure

WARNING
To avoid serious injury or death:
Z231BR-AU,Z231KH-AU,Z251BR-AU,Z251KH-AU
• Do not attempt to mount a tire on a rim. This
should be done by a qualified person with the
proper equipment.
• Always maintain the correct tire pressure.
The inflation pressure in the front tires rises
quickly when using compressed air.
Do not inflate the tires above the recommended
pressure shown in the operator's manual.
IMPORTANT :
• Do not use tires larger than specified.

5. Inflation pressure

Even though the inflation pressure is factory-set to the
prescribed level, it naturally drops slowly in the course
of time. Therefore, check it everyday and inflate as
necessary.
Tire sizes
Front 11 × 4 - 5, 4PR smooth
Rear 22 × 10 - 14, 4PR turf
(1) Ground

6. Checking transaxle fluid level

1. Park the machine on a flat surface, lower the
implement to the ground and shut off the engine
and remove the key.
