Do not engage starter when flywheel is turning.Do not start engine under load.
Above 0°C (32°F)
1. Place the transmission or other power takeoff attachments in NEUTRAL. For air start systems; check the air supply before starting the engine. There must be 690 kPa (100 psi) air pressure available.2. Move governor control lever (throttle) or depress the accelerator to half engine speed position.3. Turn the battery disconnect switch (if equipped) to the ON position. 4. Push the air start knob (1) IN, or ... ... turn the start switch (2) for marine, industrial and generator set engines or ... ... turn the start switch (3) for machines (vehicles) to the START position.
Do not crank the engine for more than 30 seconds. Allow 2 minutes for the starter to cool before cranking again. If oil pressure does not rise within 15 seconds after the engine starts, stop the engine and make necessary corrections.
5. Release the start switch or air start knob when the engine starts.6. Do not apply load to the engine or increase engine speed until oil pressure and all temperature gauges reach operating temperature. Check all gauges during the warm-up period.Below 0°C (32°F)
Ether is poisonous and flammable.Do not store replacement cylinders in living areas or in the operator's compartment.Do not smoke while changing ether cylinders.Use ether only in well ventilated areas.Use it with care to avoid fires.Avoid breathing of the vapors or repeated contact of ether with skin.Do not puncture or burn cylinders.Discard cylinders in a safe place.Keep ether container away from heat, sparks, open flame, or open sunlight. It may explode.Do not store replacement cylinders at temperatures above 49°C (120°F).Do not use cylinders in environments above 93°C (200°F).
1. Depress ether switch and hold for 3 seconds, then release. For air start system; check the air supply before starting the engine. There must be 690 kPa (100 psi) air pressure available.2. Push the air start knob IN or turn the start switch for engines, or turn the start switch for machines (vehicles) to the START position.3. Begin cranking the engine, and depress ether switch and hold for 3 seconds then release. Additional injections of ether may be required to start and/or achieve low idle speed.4. Operate the engine at low speed and/or load until all systems reach operating temperatures. Check all gauges during the warmup period.
Do not use excessive starting fluid during starting or after the engine is running. Do not crank the engine for more than 30 seconds. Allow 2 minutes for the starter motor to cool before cranking again.If oil pressure does not rise within 15 seconds after the engine starts, stop the engine and make necessary corrections.
Turn the battery disconnect switch (if equipped) OFF after the engine is stopped to prevent battery discharge while starter motor is cooling.For starting below -18°C (0°F), use of optional cold weather starting aids are recommended. A coolant heater or extra battery capacity may be required.For temperatures below -23°C (-10°F), consult your Caterpillar dealer or refer to the "Cold Weather Operation
