CARTRIDGE GP-VANE PUMP 1555091 - Caterpillar

Refer to the Owner's Manual of the OEM for your type of controls. Use the following procedure to start the engine.
DO NOT USE ETHER (starting fluids) unless specifically instructed to do so. If the engine is equipped with an Air Inlet Heater (electrically or fuel ignited manifold heater), DO NOT use ether (starting fluids) at any time. The use could result in engine damage and/or personal injury.
Startability will be improved at temperatures below 0 °C (32 °F) from the use of a jacket water heater or from other means that are used to heat the crankcase oil. This will help reduce white smoke and misfire during start-up in cold weather. Additional batteries or extra battery capacity may be required in order to start the engine at colder temperatures.Note: Consult your Caterpillar dealer before installing an oil heater. Immersion oil heaters are NOT recommended for heating of the engine oil.
When using ether (starting fluid), follow the manufacturer's instructions carefully, use it sparingly and spray it only while cranking the engine. Excessive ether can cause piston and ring damage. Use ether (starting fluid) for cold weather starting purposes only.
For engines that are not equipped with an Air Inlet Heater, use ether when temperatures are below 0 °C (32 °F). If the engine is equipped with an injection system for starting fluid, crank the engine. Depress the ether switch for three seconds. Additional injections may be necessary in order to start the engine.Note: If the engine has not been run for several weeks, fuel may have drained. Air may have moved into the filter housing. Also, when fuel filters have been changed, some air will be left in the filter housing. Refer to the Operation and Maintenance Manual, "Fuel System - Prime" topic for more information.
Place the transmission in NEUTRAL. Disengage the flywheel clutch in order to allow the engine to start faster. This also reduces draining of the battery.
Move the throttle to the low idle position.
Turn the ignition switch to the ON position.
Do not engage the starting motor when flywheel is turning. Do not start the engine under load.If the engine fails to start within 30 seconds, release the starter switch or button and wait two minutes to allow the starting motor to cool before attempting to start the engine again.
Push the start button or turn the ignition switch to the START position in order to crank the engine.
As soon as the engine starts, release the start button, or the ignition switch.
Oil pressure should rise within 15 seconds after the engine starts. Do not increase engine speed until the oil pressure gauge indicates normal. If oil pressure is not indicated on the gauge within 15 seconds, DO NOT operate the engine. STOP the engine, investigate and correct the cause.
Allow the engine to idle for approximately five minutes. Idle the engine until the water temperature gauge has begun to rise. Check all gauges during the warm-up period.Note: Oil pressures and fuel pressures should be in the normal range on the instrument
