Check fuel lines



Check all fuel lines and hose clamps for signs of
wear or damage. Check that the fuel lines are
routed so that they do not get damaged due to
abrasion. In case a fuel hose needs to be
replaced, replace all hoses and clamps at the
same time. Use fuel line that meets original
specifications. Make sure that fuel lines are not
tied to electric cables.



Check the fuel tank externally. Check for
abrasions, signs of deformation, and other wear.
Damaged fuel tank must be replaced.



Check the fuel cap and its threads. Clean the
cap if necessary. Check that the fuel cap
tightens on threads of the fuel tank and that the
ratchet system of the cap works. Use only
original type of fuel cap.

Clean fuel tank

Drain and clean the fuel tank annually. If you refuel
the loader frequently with fuel containers the fuel
tank may need to be cleaned more frequently.

To minimise waste operate the loader until the fuel
tank is near empty before cleaning the fuel tank or
taking the loader to annual service. To clean the fuel
tank remove the fuel tank from the loader, flush the
fuel tank by adding a small amount of fresh fuel, then
shake the tank, and finally drain fuel from the tank to
a waste fuel container. Repeat this a few times.

Take waste fuel to appropriate recycling and disposal
station which can dispose of used fuel properly.
Never drain fuel or oil into the environment or to
sewage drains.

Check the battery and its cables,

installation, condition, and charge

capacity

Check the cleanliness, fastening, and condition of
the battery and its electric cables as shown on page
114.

Performance of the battery

If the performance of the battery has degraded, test
the performance of the battery with dedicated service
tool. A voltage reading of a battery does not give
good indication of its condition. Checking the
performance of the battery requires a suitable testing
tool, contact your Avant service.

If necessary, replace the battery with a battery that is
identical type and size as the original one. Make sure
the battery is fastened correctly, and that battery
cables are in good condition. Also check that the
cables are routed and fastened so that they will not
get damaged in use.

The battery is sealed and maintenance free,
meaning that it doesn't need and can’t be refilled with
water during its lifetime. Do not attempt to open the
cover of the battery.

Battery type:

If the battery needs to be replaced, replace it only
with a correct type of battery. Wrong type of battery
can cause risks of fire, explosion, and release of
battery acid. The battery must meet the
specifications of the original battery.

Check electric cables, relays,

and other electric components

Check other electric cables and their routing and
fastening as shown on page 114. If you see signs of
damage on electric cables or components, stop
using the loader and disconnect the battery. Replace
the cables and insulators before you continue to use
the loader.

Check the relays, cables, and fuse boxes near the
hydraulic oil cooler on the right side of front frame.
Make sure all connectors are fully in place. Check all
cables and individual conductors for signs of
damage.

12.

Check hydraulic hoses and

fittings

Check the positioning and routing of the hydraulic
hoses. The outer layer of any hydraulic hose must
not be damaged so that any inner layer is visible.
Replace hoses that show signs of damage.

Move the hoses manually and see if the fittings of the
hoses are loose. Check if hydraulic fittings show
signs of leakage.

Hydraulic hoses age over time. Exposure to sunlight
can accelerate aging of the hoses. Replace any hose
that has cracks on its surface when you bend the
hose.
