MACHINE PARKING SAFETY Before loading, secure the uppercarriage with the undercarriage with the lock pin (if lock pin is installed). Park the excavator only on firm and level ground. If it becomes necessary to park the machine on a grade, properly block and secure it with wedges. Align the machine with the loading ramp. Lock the uppercarriage with the lock pin (if lock pin is installed). Attach the manual control levers to the foot pedals for sensitive control. Lower the attachments to the ground and anchor the bucket lightly in the ground. 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. Be careful to crushing risks when handling and applying these wedges. Keep clear of wheels and do not attempt to chock or block the machine before its complete standstill. 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.

Proceed with the same precaution while climbing up and down the cab, as for the ascension of the machine Retract the attachment as far as possible and lower the attachment as close as possible to the loading surface and carefully drive up the ramp and onto the flat bed trailer. Before climbing down the cab, you must make sure the machine is parked on a flat, firm and level ground and the ladders and steps are aligned on upper and undercarriage. When the excavator is on the trailer, release the uppercarriage lock pin, turn the uppercarriage back and lower the attachment.

If the backhoe attachment is attached, tilt the stick and bucket in and relock the uppercarriage (if lock pin is installed). Then open the cab door and lock it in opened position and make sure it is securely fixed in this position. Be aware of difficult weather conditions and anticipate their possible consequences. The wind for example could slam the cab door. If necessary unfasten the seat belt. Carefully secure the uppercarriage 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 begin climbing down, facing the machine and always holding the contact at three points, keeping the contact with the access components at the same time with two hands and one foot or with one hand and the two feet, until you reach the height where you can close the cab door in the best conditions, keeping yourself apart from its slewing range. Unlock the door using the unlocking lever designed for this purpose and close the door guiding it by the handle. If you want so lock the door and take away the key. 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, underpasses, utility lines, and in tunnels. During the unloading procedure, proceed with the same care and caution as during the loading procedure. Remove all chains and wedges. Start the engine as outlined in the Operation and Maintenance Manual. Carefully drive off the loading platform. Keep the attachment as close as possible to the ground level. Have another person guide and signal you. Slowly and carefully go down to the floor. Lock the cab, covers and boxes, remove all keys and secure the excavator against vandalism, unauthorized use, and any attractive nuisance.

MACHINE TRANSPORTING SAFETY Use only suitable transporting and lifting devices with sufficient capacity. Park the machine on firm and level ground and block the chains or wheels. If necessary, remove part of the attachments during transport. When loading the machine on a flatbed trailer or railroad car, be sure that the loading ramp incline is less than 30° and covered with wooden planks to prevent skidding. Remove all mud, snow or ice from track components before moving up the ramp. 2.7
