device designed for this specific application.
Allow only experienced persons to attach loads or to guide operators. The guide must be
visible by the operator and/or must be in voice contact with him.
Depending on the attachment combination, it is possible for the bucket teeth to hit the cab,
the cab protection or the boom cylinders. Be very careful when the bucket teeth get in this
range to prevent any damage.

MACHINE PARKING SAFTY

Park the excavator only firm and level ground.
If it is becomes necessary to park the machine on a grade, properly block and secure it with
wedges.
Lock the upper-carriage with the lock pin.
Lower the attachments to the ground and anchor the bucket lightly in the ground.
Bring all operating levers in neutral position and engage the travel and swing brakes.
Turn the engine off as outlined in the Operation and Maintenance Manual and raise the
safety lever before you leave the operator’s seat.
Lock the machine, remove all keys and secure the excavator against vandalism and
unauthorized use.

MACHINE TRANSPORTATION SAFETY

Use only suitable transporting and lifting devices with sufficient capacity.
Park the machine on the firm and level ground and block the chains.
If necessary, remove the working device during transport.
When loading the machine on a flatbed trailer or railroad car, be sure that the loading ramp
incline is less than 30

º

and covered with wooden planks to prevent skidding.

Remove all mud, snow or ice from track components before moving up the ramp.
Before loading, secure the upper-carriage with the under- carriage with the lock pin.
Align the machine with the loading ramp.
Attach the manual control levers to the foot pedals for sensitive control.
Have another person guide and signal the operator.
Have blocks or wedges ready to block the machine, if necessary, to prevent the machine from
rolling backwards.
Retract the working device as far as possible and lower the working device as close as
possible to the loading surface and carefully drive up the ramp and onto the flat bed trailer.
When the Excavator is on the trailer, release the upper-carriage lock pin, turn the upper-
carriage back and lower the working device. If the backhoe working device is attached, tilt the
stick and bucket in and relock the upper-carriage.
Carefully secure the upper-carriage and other parts with chains, wedges and blocks to prevent
slipping.
Release the hydraulic pressure, remove the ignition key, raise the safety lever, close and lock
the cab and close and secure all other doors and leave the machine.
Carefully check out the transport route. Make sure that width, height and weight allowances
are within the permitted limits. Check that there is enough clearance underneath all bridges,
