General Information
20
Most accidents involving bus operation and maintenance are caused by failure to observe basic safety
rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations
before the accident occurs.
Improper operation, lubrication, or maintenance of the coach can be dangerous and could result in injury
or death. Do not perform any lubrication or maintenance on the coach until you read and understand the
instructions in this manual or in the manufacturer-prepared operations and maintenance manuals pro-
vided for the engine, transmission, and other subsystems.
• Do not burn discarded Teflon seals; toxic gases are produced.
• Never dry bearings by spinning them with compressed air. Spinning
a bearing without lubrication can damage the bearing or cause it to
disintegrate.
• Attach a “Do Not Operate” tag to the start switches and controls at the
driver’s area and the rear control panel before servicing or repairing
the engine or transmission or attached components.
• Disconnect all batteries before servicing the electrical system.
• Stay clear of all moving parts and do not wear loose clothing or jewelry
while servicing the bus.
• Relieve all pressure in air, hydraulic, oil, fuel, or coolant lines before
any lines, fittings, or related items are disconnected or removed.
• All fuels, most lubricants, and some coolants are flammable and must
be handled with caution.
• Keep all fuels and lubricants in properly marked containers and store
away from all unauthorized persons.
• Store all oily rags or other flammable material in a protective container
and keep the container in a safe place.
• Do not bend or strike high pressure lines. Do not install bent or
damaged lines, tubes, or hoses.
• Disconnect the batteries and I/O system components when arc-welding
anywhere on the coach; this helps to protect sensitive electronics. See
“Welding Precautions” later in this section.
• In some cases, the auxiliary coolant heater (optional) will operate
even with the ignition turned off. This may create a fire or exhaust gas
hazard in an enclosed space. Always make sure the coolant heater has
not been unintentionally left on when you leave the bus.
