• Hard hats, protective glasses, protective shoes, gloves, reflector type vests, respirators and ear protection are examples of types of equipment that may be required. Certain protective equipment should be replaced and renewed upon age and wear. Old hard hats may not afford the original users intention.
• Faded and soiled vests are no longer as highly visible as original intended. See the manufacturer’s recommendation. Do not rush. Walk, do not run. Know and use the hand signals required for particular jobs and know who has the responsibility for signaling.

• Do not operate this excavator or perform maintenance work if you have not had appropriate training and have not read and fully understand the instructions and warnings in this manual.
• Wear the seat belt at all times when operating the excavator. Inspect the seat belt end mounting bolts on a daily basis to ensure their integrity.
• Make sure all protective guards are in place and secure. Remove all loose objects stored in the excavator. Remove all objects which do not belong in or on the excavator and its equipment.
