Operator Maintenance
Follow
the
manufacturer's
maintenance to make sure the forklift continues to meet
manufacturer's specifications. Failure to properly maintain
the forklift can result in improper performance, which could
cause death, serious injury, or property damage.
NOTE: Keep the Operation and safety manual in the protective
case provided inside the operator cab, as shown below.
In liquid-cooled engines, the coolant must be conditioned
and monitored, otherwise the engine could be damaged by:
•
Corrosion
•
Cavitation
•
Freezing
•
Overheating
The right water quality is important for conditioning the cool-
ant. Clear, clean water within the following analysis values
should always be used:
The conditioning of the coolant for liquid-cooled DEUTZ com-
pact engines is performed by mixing an anti-freeze with cor-
rosion protection inhibitors based on ethylene glycol into the
water. The cooling system corrosion protection agent should
be free from nitrite, amine, and phosphate to protect the ma-
terials used in DEUTZ engines.
The cooling system must be monitored regularly. This also
includes checking the coolant system corrosion protection
agent concentration in addition to checking the coolant level.
The cooling system corrosion protection agent concentration
can be checked with conventional test instruments (e.g. re-
fractometer).
At temperatures below -41 °C, please contact your local
Xtreme Manufacturing or DEUTZ partner.

It is possible to use other cooling system corrosion protection
agents (e.g. chemical corrosion protection agents) in excep-
tional cases. Consult your Xtreme Manufacturing or DEUTZ
partner.
Check coolant reservoir level only when the engine is cool to
touch. Add coolant, if necessary.

Modern diesel engines place very high demands on the lubri-
cating oil to be used. The specific engine performances lead to
an increased thermal load on the lubricating oil. The lubricat-
ing oil is also more exposed to contamination due to reduced
oil consumption and longer oil change intervals. For this rea-
son it is necessary to observe the requirements and recom-
mendations described in this operating manual in order not
to shorten the life of the engine.
Lubricating oils always consist of a base oil and an additive
package. The most important tasks of a lubricating oil (e.g.
wear protection, corrosion protection, neutralization of acids
from combustion products, prevention of coke and soot de-
posits on the engine parts) are assumed by the additives. The
properties of the base oil are also decisive for the quality of the
product, e.g. with regard to thermal load capacity.

Never remove the radiator cap while the
engine is hot. The cooling system is under
pressure. Hot coolant could cause severe
burns or eye injury. Wear protective clothing
and safety glasses.
