MAINTENANCE
The preventive maintenance which you yourself
carry out is the most important form of care. It in-
volves lubrication and various checks and adjust-
ments.
Most of these service measures are easy to per-
form and do not require any detailed explanation.
In some cases, however, more detailed instructions
are needed, as described in the following.
DIESEL ENGINE
Running in
Observe the following during the running-in pe-
riod. Change the engine oil and oil lter after 50
hours of service. Never run the machine when it is
cold, but rst let the engine and the hydraulic oil
become warm.
Measures during cold weather
Under winter conditions with temperatures below
0°C observe the following:
· Make certain the cooling water has sufcient
anti-
freeze protection according to the instructions
on
page 22.
· Use oils recommended for winter use, see page
34.
· Fill the fuel tank after nishing your work to
prevent
the formation of condensation water in the tank.
Valve mechanism
Check the valve clearance after every 800 hours
of service. If necessary, adjust the clearance. This
valve adjustment must be carried out by an autho-
rized service centre.
