STARTING AND OPERATING THE VEHICLE CAUTION: Never operate the starter motor while the engine is running. The starter and flywheel gears could clash or jam, severely damaging them. • Wait until normal engine oil pressure registers on the gauge before idling or accelerating the engine beyond 1000 rpm. • Watch the air pressure gauge. Wait until both pointers register at least 100 psi (689 kPa) before releasing the spring brake and moving the vehicle. Also, check the alarm system for any type of faults and correct them before moving the vehicle. CAUTION: Do not try to put the vehicle in motion before pressure in the air system reaches 100 psi (689 kPa) because the wheels will still be locked by the spring brake action. • Unnecessary stress and possible brake malfunction could occur if the vehicle is forced to move before the air system reaches 100 psi (689 kPa). Starting Procedure — Cold Temperatures In addition to the previous “Normal Starting Procedures,” use these Cold Weather Starting guidelines when the air temperature falls below a certain temperature. Check your Engine Operation and Maintenance Manual for further details on when cold weather starting aids are needed. Using special cold-starting equipment will help the engine start easier. And in cold weather, fast engine starting helps relieve the loads on the electrical system and cranking motor. If you follow these few simple guidelines, you will extend the service life of your vehicle's engine: • Keep the electrical system in top condition. • Use the best quality and recommended grade of fuel (see Engine Operation and Maintenance Manual). • Use the recommended engine lubricating oil. • As stated in the Normal Starting Procedures, when temperatures are below normal, fully depress the accelerator pedal after engaging the starter. – 92 – Y53-6027 Medium Duty (R05/09)

STARTING AND OPERATING THE VEHICLE Engine Block Heater (Option) To preheat the engine before starting, plug the optional engine block heater into a properly grounded AC electrical source. Do not start the engine with the heater plugged in. WARNING! Engine block heaters can cause fires resulting in death or serious personal injury and/or property damage if not properly maintained and operated. Regularly inspect the engine block heater wiring and connector for damaged or frayed wires. Do not use the heater if there are any signs of problems. Contact your Authorized Service Center or the manufacturer of the heater if you are in need of repairs or information. CAUTION: Always unplug the heater before starting the engine. Damage to the cooling system could occur if the heater is not turned OFF (unplugged). When the temperature falls below 0°F (–18°F) for Caterpillar engines, or –10°F (–24°C) for Cummins engines, the block heater is required. • Use a solution of half ethylene glycol antifreeze and half water for best heater performance. Do not exceed 60 percent concentration of antifreeze, as it can shorten heater life. See page 146 for more information. • After servicing the cooling system, operate the vehicle for a day or two before using the heater. Trapped air inside the engine needs time to escape. Cold Weather Starting—Air Intake Heater Do not use ether or any other starting fluid as a cold starting aid in your Medium Duty vehicle. Engine conditions are automatically monitored and in cold weather the fuel/ air mixture is preheated in the manifold. WARNING! Do not use ether or other starting fluids as a cold-starting aid in your Medium Duty vehicle. Your engine uses either an electrical grid or an open flame inside the manifold, to heat the air/fuel mixture for cold weather starting. If ether or another starting fluid is used, the air/fuel will ignite inside the manifold, which could cause an explosion and death or severe injury. Medium Duty (R05/09) Y53-6027 – 93 –

Engine Block Heater (Option)<br />

To preheat the engine before starting, plug the optional<br />

engine block heater into a properly grounded AC electrical<br />

source. Do not start the engine with the heater plugged in.<br />

WARNING! Engine block heaters can cause<br />

fires resulting in death or serious personal<br />

injury and/or property damage if not properly<br />

maintained and operated. Regularly inspect<br />

the engine block heater wiring and connector<br />

for damaged or frayed wires. Do not use the<br />

heater if there are any signs of problems. Contact<br />

your Authorized Service Center or the<br />

manufacturer of the heater if you are in need<br />

of repairs or information.<br />

CAUTION: Always unplug the heater before<br />

starting the engine. Damage to the cooling<br />

system could occur if the heater is not turned<br />

OFF (unplugged).<br />

When the temperature falls below 0°F (–18°F) for Caterpillar<br />

engines, or –10°F (–24°C) for Cummins engines, the<br />

block heater is required.<br />

Cold Weather Starting—Air Intake Heater<br />

Do not use ether or any other starting fluid as a cold starting<br />

aid in your <strong>Medium</strong> <strong>Duty</strong> vehicle. Engine conditions<br />

are automatically monitored and in cold weather the fuel/<br />

air mixture is preheated in the manifold.<br />

WARNING! Do not use ether or other starting<br />

fluids as a cold-starting aid in your <strong>Medium</strong><br />

<strong>Duty</strong> vehicle. Your engine uses either an electrical<br />

grid or an open flame inside the manifold,<br />

to heat the air/fuel mixture for cold<br />

weather starting. If ether or another starting<br />

fluid is used, the air/fuel will ignite inside the<br />

manifold, which could cause an explosion and<br />

death or severe injury.<br />
