Operator Maintenance; Coolant - Xtreme Manufacturing XR5919-A Operation And Safety Manual

y Align the wheels and set the Steering Select
switch to 2 wheel (2W) steering.
• Align the wheels and set the Steering Select
switch to 4 wheel (4W) steering.
13. Check the gauges on the display after the engine
warms to the proper operating range.
• Check the voltage gauge. The voltage gauge
should read between 12.5 to 14 Volts.
• Check the engine coolant temperature gauge.
The engine coolant temperature gauge should
read between 180 to 200°F.
• The Oil Pressure Indicator will be displayed when
the engine oil pressure is below normal. If the
Oil Pressure Indicator comes on during normal
operation, stop the telehandler, follow proper shut
down procedures, tag telehandler with "Do Not
Operate" tags, and have a qualified mechanic
service or repair the telehandler BEFORE placing
it into service again.

Operator Maintenance

Warning
Follow the manufacturer's instructions for proper
maintenance to make sure the telehandler contin-
ues to meet manufacturer's specifications. Failure
to properly maintain the telehandler can result in
improper performance, which could cause death,
serious injury, or property damage.

Coolant

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
coolant. Use clear, clean water within the analysis values
in Figure 5.1.

Chapter 5 – Pre-Operation Inspection
Figure 5.1 – Water Quality
The conditioning of the coolant for liquid-cooled Deutz
compact engines is performed by mixing an anti-freeze
with corrosion protection inhibitors based on ethylene gly-
col into the water. The cooling system corrosion protection
agent should be free from nitrite, amine, and phosphate
to protect the materials 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 concen-
tration can be checked with conventional test instruments
such as a refractometer (refer to Figure 5.2).

At temperatures below -42°F, 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 exceptional cases. Consult your local Xtreme
Manufacturing or Deutz partner.
