Stopping the Engine
1. Park the machine on level ground, if possible.
Important: If you must temporarily park the
machine on a slope or an incline, position the
machine at a right angle to the slope. Ensure that
the machine is behind an object that will not move.
2. Lower all attachments to the ground.
3. Set the parking brake.
4. Reduce the engine speed to idle and allow it to run for
3 to 5 minutes to adequately cool the engine.
5. Turn the key switch to the Off position.
Note: If you leave the machine unattended, remove
the key from the key switch.
Breaking in a New or Rebuilt Engine
During the first 20 hours of operation of a new or rebuilt
engine, do the following:
•
Run the engine at a normal operating temperature.
•
Do not run the engine at low idle speeds for long periods
of time.
•
Operate the machine with normal loads for the first 8
hours.
•
Do not use special "break-in" lubricating oil. Use the
specified oil; refer to
Checking the Engine-Oil Level (page
24)
and
Servicing the Engine Oil and Filter (page

Operating the Machine in
Extreme Conditions
Both hot and cold weather place unusual demands upon
the machine and the attachments. You can minimize
temperature-related problems on the machine by performing
the following steps:
Operating the Machine in Hot Weather
1. Clean all dirt and debris from the radiator, heat
exchanger, hydraulic-fluid cooler, and engine area to
ensure that there is proper air flow to cool the engine.
2. Remove any debris from the air inlets in the nose and
side panels.
3. Use lubricants that have the correct viscosity; refer to
Checking the Engine-Oil Level (page
4. Operate the machine at an appropriate engine speed
and transmission range for the operating conditions;
do not overload the engine.
5. Use pressure-testing equipment to test the radiator cap
before the hot weather begins; replace the cap if it is
damaged.
6. Maintain the correct coolant level in the reservoir and
in the radiator, and ensure that there is a mixture of
50% ethylene glycol and 50% water in the cooling
system.
Operating the Machine in Cold Weather
Operating your machine in cold weather requires special
attention to prevent serious damage to the machine.
Performing the following procedures will extend the service
life of your machine:
1. Clean the battery and ensure that it is fully charged.
Note: A fully charged battery at -17ºC (0ºF) has
only 40% of the normal starting power. When the
temperature decreases to -29ºC (-20ºF), the battery has
only 18% of the normal power remaining.
Note: The machine comes with a maintenance-free
battery. If you use a different battery and add water to
it when the temperature is below 0ºC (32ºF), ensure
that you charge the battery or run the engine for about
2 hours to prevent the battery from freezing.
2. Inspect the battery cables and terminals. Clean the
terminals, and apply a coat of grease on each terminal
to prevent corrosion.
3. Ensure that the fuel system is clean and free of water;
refer to
Draining Water from the Fuel-Water Separator
(page
23).
Note: Use the proper fuel for cold weather.
Note: To help prevent condensation from building
up in the fuel tank, fill up the fuel tank at the end of
each day.
