Safe Operation Needs A Qualified Operator

For an operator to be qualified, he or she must not use drugs or alcoholic drinks which impair alertness or coordination while working. An operator who is taking prescription drugs must get medical advice to determine if he or she can safely operate a machine and the attachment

A Qualified Operator Must Do The Following:
Understand the Written Instructions, Rules and Regulations

• The written instructions from Bobcat Company include the Delivery Report, Operation & Maintenance Manual, Operator’s Handbook, Safety Manual and machine signs (decals).
•  Check the rules and regulations at your location. The rules may include an employer’s work safety requirements. Regulations may apply to local driving requirements or use of a Slow Moving Vehicle (SMV) emblem. Regulations may identify a hazard such as a utility line.

Have Training with Actual Operation

• Operator training must consist of a demonstration and verbal instruction. This training is given by your Bobcat dealer before the product is delivered.
• The new operator must start in an area without bystanders and use all the controls until he or she can operate the machine and attachment safely under all conditions of the work area. Always fasten seat belt before operating.

Know the Work Conditions

• • Know the weight of the materials being handled. Avoid exceeding the machine load capacities. Material which is very dense will be heavier than the same volume of less dense material. Reduce the size of load if handling dense material.
• The operator must know any prohibited uses or work areas, for example, he or she needs to know about excessive slopes.
• Know the location of any underground lines. Call local utilities or the TOLL FREE phone number found in the Call Before You Dig Section of this manual.
• Wear tight fitting clothing. Always wear safety glasses when doing maintenance or service. Safety glasses, respiratory equipment, hearing protection, Special Applications Kits or a Front Window Guard are required for some work. See your Bobcat dealer about Bobcat Safety equipment for your machine.
