Avoid Dozer Blade Impact
Fig. 4-41
0002874
Do not strike rocks or other hard objects with the dozer
blade. This can shorten the service life of the dozer blade or
the hydraulic cylinder.
Avoid Shifting Travel Directions Suddenly
•
Never jerk the control levers. Jerking the control levers
can cause travel motor strain and shorten the service
life.
•
Avoid moving the control levers quickly from forward
travel to reverse travel.
•
Never quickly move the control levers from high speed
to neutral.

When the dozer blade is used as a stabilizer, never use one
end of the blade to support the machine.
Excavating Hard Ground
Use alternate work equipment to break up hard ground before excavation to prevent machine damage.
