engine.
1. Check for leaks under the machine. Repair leaks as
necessary.
2. Check the tires for wear and damage.
3. Check the machine for debris, especially around the
engine area. Make sure this area is clean so engine
cools properly.

the 10 hour items.
NOTE:
If this is a new machine or a machine with a
rebuilt engine, see Run-In procedure.
Run-In Procedure For a New Machine
During the first 20 hours of operation for a new machine
or a machine with a rebuilt engine, the following
procedure should be followed:
8. Keep the engine at normal operating temperatures.
9. Do not run the engine at low idle speeds for long
periods of time.
10. Operate the machine with normal loads for the first
eight (8) hours.

OPERATING IN HOT WEATHER
Extreme conditions, hot or cold, place unusual demands
on equipment. The owner or operator can minimize
temperature related problems on equipment by following
these general recommendations.
1. Clean all dirt and debris from the radiator and engine
area to make sure there is proper air flow to cool the
engine. Wipe debris from air inlets in the hood side
panels.
2. Use lubricants of the correct viscosity. See the
Recommendation Chart in this manual.
3. Check the air cleaner dust valve more frequently
during extreme dust conditions.
4. Use the correct engine speed and transmission range
for your operating conditions. Run the engine at high
idle. Do not overload or lug down the engine.
OPERATING IN COLD WEATHER
Cold weather conditions cause special problems. During
these conditions your machine will require special
attention to prevent serious damage. Cold weather
maintenance will extend the service life of your machine.
1. BATTERY AND ELECTRICAL SYSTEM: Clean the
battery and make sure the battery is at full charge.
NOTE:
A fully charged battery at -17°C (0°F) has
only 40 percent of the normal starting power. When
the temperature decreases to -29°C (-20°F), the
battery has only 18 percent of the power remaining.
WARNING
: Before starting engine, study
operator’s manual safety messages. Read all
safety signs on machine. Clear the area of other
persons. Learn and practice safe use of controls
before operating. It is your responsibility to
understand and follow manufacturer’s
instructions on machine operation, service, and
to observe pertinent laws and regulations.
Operators and service manuals can be obtained
from your equipment dealer.
