Daily inspections and maintenance
2. Cleaning of the loader
Pay special attention to the cleanliness of the engine
compartment and engine bay, battery, and radiators.
A dirty machine will run hotter and can cause poor
performance, shorter battery life, or stopping of loader
due to overheating.
Cleanliness of the loader is not only a question of outer
appearance. All surfaces, painted and others, will stay in
better condition when they are kept clean.
Keep all lights, windows, and mirrors clean to ensure
visibility.
You can wash the outer surfaces of the loader carefully
with a pressure washer. Never use the pressure washer
to clean the inner parts of the loader or the battery,
electric parts may become damaged. Wash hydraulic
components (hoses, ttings, cylinders, valves), any
electric component, decals, and the radiators carefully,
never with a high pressure washer.
NOTE: There is a service hatch on the underside of the
loader to help the cleaning of the rear frame. Reinstall
the cover plate after cleaning to protect the internal
components of the loader.
Clean the cab interior with an appropriate mild detergent
and cleaning supplies.
After washing with a pressure washer grease all greasing
points.
Never spray the engine
compartment or radiators with a
pressure washer. Cooling radiators
and electric equipment, their
connectors and insulators, and the
battery may get damaged. Use
cool or warm water to wash other
parts of the loader. Never use hot
water (above 160ºF / 70ºC).
Clean cooling systems
There are two cooling fans on the loader:
• Hydraulic oil cooler
• Engine cooler
Keep both coolers clean to ensure reliable operation and
long service life of the loader.
If you operate the loader in dusty conditions, clean the
cooling fans and surfaces more frequently.
The loader is equipped with a
hydraulic oil cooler, which is located
at the right side of the loader, near
the controls of the loader. Make
sure to clean the oil cooler cell
with compressed air every time
you are servicing the loader - and
even more frequently if the loader
is operated in dusty conditions.
Proper cooling is essential. To
prevent overheating, clean screens,
cooling ns, and external surfaces
of electric motors, inverters, and
the charger. Avoid spraying water
at wiring harness or any electrical
components.
