STARTING THE ENGINE (CONT’D)
Warming The Hydraulic / Hydrostatic System
Let the engine operate for a minimum of 5 minutes to
warm the engine and hydrostatic transmission fluid
before operating the loader
When the temperature is below -30°C (-20°F),
hydrostatic oil must be warmed before starting. The
hydrostatic system will not get enough oil at low
temperatures and will be damaged. Park the machine
in an area where the temperature will be above -18°C
(0°F) if possible.

If the temperature is below freezing, perform the following
to make starting the engine easier:
• Replace the engine oil with the correct type and
viscosity for the anticipated starting temperature.
(See Engine Oil Chart on Page 161.)
• Make sure the battery is fully charged.
• Install an engine heater, available from your Bobcat
loader dealer.
NOTE: The display screen of the Deluxe
Instrumentation Panel may not be at full
intensity when the temperature is below -26°C
(-15°F). The display screen may take 30
seconds to several minutes to warm up. All
systems remain monitored even when the
display screen is off.
