1. CLEANING OF THE LOADER
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 clean machine also lasts longer. A dirty
machine will run hotter and will collect dirt into the
air cleaner, which is likely to damage the engine. Pay
special attention to the cleanliness of the engine, the
oil tank cover, the engine compartment and the
hydraulic pump compartment. The loader can be
washed with a pressure washer.
ATTENTION! If 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.
2. TYRE PRESSURE
Correct tyre pressure means that the tyres last much
longer. Wrong tyre pressure increases tyre wear and
can be a safety risk when working with the loader.
Recommended tyre pressures are:
- 27 x 8.50-15 tyre 2.5 bar (36.3 PSI)
- 23x10.50-12/23x8.50-12 tyre 2.0 bar (29.0 PSI)
- 26x12.00-12 tyre 2.0 bar (29.0 PSI)
3. BATTERY CHECK
In order to secure the starting and safe operation the
battery of the loader must
be checked regularly.
Checking the electrolyte
level of the battery happens
by opening the filler caps.
ATTENTION! Clean the
battery before opening
the caps so that dirt
cannot get in the battery.
Check also the contacts and clean if necessary.
4. HYDRAULIC OIL LEVEL
Hydraulic oil level can be checked with the dipstick
in the filler. Oil level should
be at the low mark in the
dipstick with the boom
raised to max. height. Refill
when necessary. Clean the
area before checking
hydraulic oil level. Do not
let any contaminents enter
the hydraulic tank during this
procedure. There is a breather filter inside the dipstick
cap which should be cleaned or changed once a year.
5.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.
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.
6. 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 38 litres. Use ISO VG-46
certified mineral hydraulic
oil (e.g. Shell Tellus TX oil).
Use of synthetic hydraulic
fluids is not allowed.
7. CHECK AND TIGHTENING OF
BOLTS, NUTS AND FITTINGS
Check tightness of bolts, nuts and hydraulic fittings
regularly. ATTENTION! Tighten wheel nuts after
first 5 operating hours. Check tightness of wheel
nuts regularly. Wheel nuts shall first be tightened
to 120 Nm diagonally opposite and finally
tightened to 140 Nm.
8. CHECK PRESSURE OF HYDRAULIC SYSTEM
Pressure checking points for different functions are
as follows:
Boom lifting: Pressure is checked from the
manometer fitting which is mounted on the main
control valve (or from the
quick coupler of rear
auxiliary hydraulics if the
machine is equipped with
rear aux. hydraulics outlet.)
Pressure is measured with
full engine revs and by
turning e.g. the bucket tilt control to end position.
Pressure setting should be 205 bar.
