4.12 DAILY MAINTENANCE _____________________________________________________

Important: 

For more detailed maintenance information,

adjustments, and maintenance/lubrication charts, see the

Parts & Maintenance

 manual.

1.

Park the mower on a flat, level surface. Fully lower the
implements to the ground, engage parking brake, stop
the engine, and remove key from ignition switch. 

2.

Grease and lubricate all points if required. To prevent
fires, wash the cutting units and mower after each use.

a.

Use only fresh water for cleaning your equipment.

Note: 

Use of salt water or effluent water has been

known to encourage rust and corrosion of metal parts
resulting in premature deterioration or failure.
Damage of this nature is not covered by the factory
warranty.

b.

Do not use high pressure spray.

c.

Do not spray water directly at the instrument panel,

or any electrical components.

d.

Do not spray water into the cooling air intake or the

engine air intake.

3.

Fill mower’s fuel tank at the end of each operating day
to within 1 in. (25 mm) below the filler neck.

Use clean, fresh #2 low or ultra-low sulfur diesel fuel.
Minimum Cetane Rating 45.

4.

Handle fuel with care - it is highly flammable. Use an
approved container, the spout must fit inside the fuel
filler neck. Avoid using cans and funnels to transfer
fuel.

a.

Never remove the fuel cap from the fuel tank, or add

fuel, when the engine is running or while the engine
is hot.

b.

Do not smoke when handling fuel. Never fill or drain

the tank indoors.

c.

Never overfill or allow the tank to become empty.

Do not spill fuel. Clean any spilled fuel immediately.

d.

Never handle or store fuel containers near an open

flame or any device that may create sparks and
ignite the fuel or fuel vapors.

5.

Store fuel according to local, state, or federal
ordinances and recommendations from your fuel
supplier.

6.

Inspect hydraulic hoses and tubes daily. Look for wet
hoses or oil spots and replace worn or damaged hoses
and tubes before operating the machine.

7.

Check the engine oil and hydraulic oil at the start of
each day, before starting the engine. If the oil level is
low, remove the oil filler cap and add oil as required. Do
not overfill.

NOTICE

Do not wash a hot or running engine. Use compressed
air to clean the engine and radiator fins.

 

WARNING

To prevent serious injury from hot, high pressure oil,
never use your hands to check for oil leaks, use paper or
cardboard.

Hydraulic fluid escaping under pressure can have
sufficient force to penetrate skin. If fluid is injected into
the skin, it must be surgically removed within a few hours
by a doctor familiar with this form of injury or gangrene
may result.

NOTICE

Care must be used at all times to avoid any
contamination of the hydraulic system. Follow
recommended maintenance practices and adhere to
scheduled intervals for hydraulic oil and filter changes.
Introduction of any type of contamination may result in
operating issues by causing valves to stick or leak
internally.
