SAFE OPERATION NEEDS A QUALIFIED OPERATOR*

A QUALIFIED OPERATOR MUST DO THE FOLLOWING:

• UNDERSTAND THE WRITTEN INSTRUCTIONS, RULES AND REGULATIONS

• The written instructions from Melroe Company include the delivery report, operator handbook, Operation & Maintenance Manual, and machine signs (decals).

• Check the rules and regulations at your location.

• HAVE TRAINING WITH ACTUAL OPERATION

• Operator training must consist of a demonstration and verbal instruction. This training is given by your excavator dealer before the excavator is delivered.

• The new operator should start in an area without bystanders and use all the controls until he can operate safely unde r all conditions of the work area.

• KNOW THE WORK CONDITIONS

• For each material to be handled, the operator must know how to avoid exceeding the rated lift capacity of th e excavator. For example, you should not use the excavator for lifting heavy objects.

• The operator must know any prohibited uses or work areas, for example, he needs to know about excessive slopes

• Know the location of any underground lines. Call local utilities or ONE CALL before you dig.

• Wear tight fitting clothing. Always wear safety glasses when maintaining or servicing excavator. Safety glasses, hearing protection or an excavator special application kit are required for some work. See your dealer about Melro e Safety equipment.

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

Fire Prevention

The excavator has several components that are at high temperature under normal operating conditions. The primary source of high temperatures is the engine and exhaust system. The electrical system, if damaged or incorrectly maintained, can be a source of arcs or sparks. These conditions make it important to avoid applications where explosive dust or gases can be ignited by arcs, sparks or heat.

Flammable debris (leaves, straw, etc.) must be removed regularly. If flammable debris is allowed to accumulate, it will increase the fire hazard. The excavator must be cleaned as often as necessary to avoid this accumulation. This flammable debris in the engine compartment can be a fire hazard when the machine is parked with a hot engine.

If equipped the spark arrestor muffler is designed to control the emission of hot particles from the engine and exhaust system, but the muffler and the exhaust gases are still hot. This spark arrestor muffler does not change the need to avoid use of the excavator in an atmosphere with explosive dust or gases or where the exhaust can contact flammable material.

• Do not use the Hydraulic Excavator where explosive dust or gases can be ignited by arcs, sparks, hot components or exhaust gases.

• The operator cab, engine compartment and engine cooling system must be inspected every day and cleaned if necessary to prevent overheating. Remove all flammable material.

• Check all electrical wiring and connections for damage. Keep the battery terminals clean and tight. Repair or replace any damaged part.

• Check fuel and hydraulic tubes, hoses and fittings for damage and leakage. Tighten or replace any parts that show leakage. Always clean fluid spills.

• Do not use ether or starting fluids on any engine which has glow plugs. These starting aids can explode and injure bystanders.

• Always clean the excavator before doing any welding. Cover rubber hoses, battery and all other flammable parts. Keep a fire extinguisher near the machine when welding.

• Stop the engine and let it cool before adding fuel. No smoking!

• Use the procedure in Operation & Maintenance Manual for connecting the battery.

• Use the procedure in the Operation & Maintenance Manual for servicing the spark arrestor muffler (if equipped) every 100 hours of operation.

• Know where fire extinguishers and first aid kits are located and how to use them. A fire extinguisher is available from your Bobcat Dealer.
