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.
