CONTENTS
Safety instructions—Personal safety.
Special caution—Machine or component damage.
Read the entire manual before starting any
service work.
Ensure that ventilation (extraction) is adequate
if the engine is run indoors.
It is essential that the machine is properly cared for to
ensure satisfactory operation. Keep the machine clean to
facilitate quick and timely detection of any leakage, loose
bolts and loose connections.
TAKE CARE OF THE ENVIRONMENT
Do not leave behind any oil, fuel or other substances that
are detrimental to the environment.
This manual contains instructions for periodic activities
that should normally be performed by the operator.
For the diesel engine, the engine manufacturer’s
instructions—found in the engine manual—also
apply. This manual is included in the product
binder.

LUBRICANTS, SYMBOLS
Other fuel and lubricants are required for operation in extremely high or extremely low
ambient temperature. See the “Special instructions” chapter, or consult Dynapac.
Always use high-quality lubricants in the recommended amounts. Too much grease or oil can
cause overheating and subsequent increased wear.

MAINTENANCE MEASURES
The periodic measures should be performed primarily
after the specified hours of operation. Use the daily,
weekly, etc. time periods only where this is not possible.
Remove all dirt before filling, when checking
oils and fuel, and when lubricating with oil or
grease.
The engine manual specifies additional ser-
vice/maintenance instructions which relate to
the diesel engine.
