2. Cleaning of the machine
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 cleaned regularly. A
dirty machine will run hotter and will collect more dirt
into the air cleaner, which may shorten the engine life.
Pay special attention to the cleanliness of the engine, the
engine compartment, the radiators, the hydraulic pump
compartment, hydraulic quick couplings and the oil tank
cover. The outer surfaces of the loader can be washed
with a pressure washer. However, avoid direct spraying
on hydraulic components (hoses, cylinders), decals, and
the radiators. Clean cab interior with appropriate mild
detergent and cleaning supplies After washing grease all
greasing points, also the attachment coupling plate and
locking pins.
The loader is equipped with a hydraulic oil
cooler, which is located in the front frame
on the right side. 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 being used in dusty
conditions. Take off the right side cover plate
before cleaning the oil cooler.
3. Greasing of the machine
Greasing of pivot points is very important in order to
avoid wear. Most of the greasing points are on the loader
boom. The picture on page 35 shows the location of
grease nipples.
4. Battery check
Inspect and clean battery terminals regularly. Check also
condition and fastening of battery cables and terminal
insulators. Make sure that battery cables cannot chafe
against any sharp edges. Check also condition and
fastening of battery disconnect switch and cables.
5. Hydraulic oil level
Hydraulic oil level can be checked
with the dipstick in the filler.
Oil level should be at the lower
mark of the dipstick when the
loader boom is up. Refill when necessary. Do not let
any contaminents enter the hydraulic oil tank during this
procedure. There is a breather filter inside the dipstick
cap which should be cleaned or changed once a year.
Remember to use the service support (page 28).
6. Check coolant level
Never open the
pressurized radiator
while engine is warm.
Hot coolant may burst
out causing serious
burns. Allow engine to
cool completely before
opening.
7. Changing of hydraulic oil filters
The hydraulic oil return filter is
located on top of the hydraulic oil
tank, under the front cover. Take off
the cover and replace the oil filter
cartridge.
Remember to use the service
support (page 28).
The hydraulic pressure filter is located
in the back frame beside the hydraulic
pumps. When unscrewing the filter
hold the screw in the housing with a
12 mm allen key and replace the filter.
8. Hydraulic oil change
When changing hydraulic oil, the oil can be removed with
a suction pump or by opening the drain plug on the right
side of the front frame, next to the articulation joint. In
both cases it is important to clean
the magnetic drain plug. Hydraulic
oil tank capacity is 36 litres. Use
ISO VG-46 certified mineral
hydraulic oil.
Use of synthetic or bio
hydraulic fluids is not
allowed.
