Operation
15. Do not dig with the excavator tires raised. This can result in
structural and mechanical failures.
16. Do not operate travel lever quickly when traveling in high
range.
• Avoid sudden starts.
• When traveling in one direction come to a complete
stop before reversing directions. Do not rock
excavator back and forth with levers.
• Avoid sudden stops. Return levers to neutral by
hand. Do not let them snap back to neutral on their
own.
17. If the optional long fronts or attachments or heavy duty
front end attachments are used, the machine balance will
be altered. Follow these additional operating precautions.
18. Do not move dirt or objects by swinging the excavator into

WARNING!
Do not travel downhill with the front end attachments
raised.
Do not travel across slopes; travel straight up or down
slope.
Use extreme caution when swinging the upper frame
when positioned on a slope.
Allow extra swing stopping room. The additional
momentum generated by the longer or heavier front
end equipment will increase the amount of time
needed to stop the swing motion.
Make sure that all optional equipment has been
authorized and installed properly.
