OPERATING AND OPERATION
117
WL50
Take the following precautions at low temperatures to pre-
vent the loader from being damaged and to make the loader
easier to start:
Use the proper coolant mix.•
Use engine lubricating oil of the proper viscosity
•
class.
Use diesel fuel for low temperatures.•
Fill the fuel reservoir at the end of the work shift.•
Make sure the battery is always fully charged.•
Install the cold starting aid (see note above!).•
Hydraulic and lubricating uids are more viscous
when cold. When ambient temperatures are at or
near the freezing point of 0°C (32°F), permit the
engine, drivetrain and hydraulic system to warm up
at idle speed until the temperature indicator for the
system indicates warming has progressed.
Operate the wheel loader slowly and smoothly •
to accelerate the warming process.
Observe the hydraulic system lter pressure
•
display to determine if pressure is excessive.
Do not connect two 12V batteries in series (+
•
to –) and then connect the remaining battery
poles to the starter or starter solenoid. This will
damage the electrical system
