Hydraulic fluid cooler
Checking - Cleaning
The water and hydraulic fluid coolers are accessible
when the cooler grill (4) is removed.
Make sure that the air flow through the cooler is
unobstructed. Dirty coolers are blown clean with
compressed air or washed clean using a
high-pressure water cleaner.
Take care when using a high-pressure water jet.
Do not hold the nozzle too near the cooler.

Battery
- Check condition
The batteries are sealed and maintenance-free.
Make sure there is no open flame in the vicinity
when checking the electrolyte level. Explosive gas
is formed when the alternator charges the battery.
Fig. Batteries
When disconnecting the battery, always
disconnect the negative cable first. When
connecting the battery, always connect the
positive cable first.
The cable shoes should be clean and tightened.
Corroded cable shoes should be cleaned and
greased with acid-proof Vaseline.
Wipe the top of the battery.

Hydraulic filter
Change
Remove the filter (1) and deliver to special waste
handling. This is a single-use filter and cannot be
cleaned.
Thoroughly clean the filter holder sealing surface.
Apply a thin coat of fresh hydraulic fluid to the rubber
gasket on the new filter.
Screw the filter on by hand, firstly until the filter gasket
makes contact with the filter base. Then rotate a
further ½ turn.

Drum - Oil change
Take great care when draining the fluid. Wear
protective gloves and goggles.
Set the roller so that the drain plug (1), the large plug,
is at the lowest position in its rotation.
Place a receptacle that holds at least 20 liters (5.3 gal)

Rubber elements and attachment screws
Check
Check all rubber elements (1). Replace all elements if
25% or more than 25% of the number on one side of
the drum have cracks deeper than 10-15 mm (0.4-0.6
in).

Hydraulic reservoir cap - Check
Turn up the machine so that the tank cap is accessible
from the left side of the machine.
Unscrew and make sure that the reservoir cap is not
clogged. Air must have unobstructed passage through
the cap in both directions.

Fuel tank
- Cleaning
1
It is easiest to clean the tank when it is almost empty.
A drain plug is placed under the left side of the front
frame.
Alternatively drain the tank with a suitable pump, e.g.
an oil drain pump, to bring up any bottom sediment.
Collect the fuel and sediment in a container and
deliver to environmentally correct handling.
Fig. Fuel tank
Keep in mind fire risk when handling fuel.

Watering system
- Draining
Remember that there is a risk of freezing during
the winter. Empty the tank, pump, filter and lines,
or mix antifreeze in the water.

There is a drain cock (2) in the space for the pump
system on the central water tank. This can be used to
drain both the tank and parts of the pump system.

Steering hitch - Tightening
Nobody must be allowed near the steering joint
when the engine is running. Risk of being
crushed when the steering is operated. Switch
off the engine and activate the parking brake

before lubricating.
The easiest way to identify if you have this type of
steering hitch is that it has a new type of nut (1) at the
top, as shown.
