General

WARNING Maintenance must be done only by suitably qualified and competent persons.
Before doing any maintenance make sure the machine is safe, it must be correctly parked on solid, level
ground.
To prevent anyone starting the engine, remove the ignition key. Disconnect the battery when you are not
using electrical power. If you do not take these precautions you could be killed or injured.
A badly maintained machine is a danger to the operator and the people working around him. Make sure that
the regular maintenance and lubrication tasks listed in the service schedules are done to keep the machine
in a safe and efficient working condition.
Apart from the daily tasks, the schedules are based on the machine running hours. Keep a regular check on
the hourmeter readings to correctly gauge the service intervals. When there is no hourmeter installed, use the
calendar equivalents to determine the service intervals.
Do not use a machine which is due for a service. Make sure any defects found during the regular maintenance
checks are corrected immediately.
More frequent checks of engine components than the engine manufacturer recommends do not invalidate
emissions warranty.

How to Use the Maintenance Schedules

The schedules show the service tasks which must be done and their intervals.
The services must be done at either the hourly interval or the calendar equivalent, whichever occurs first.
The intervals given in the schedules must not be exceeded. If the machine is operated under severe conditions
(high temperature, dust, water, etc.) shorten the intervals.
