Information:
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.Keep the ether cylinders out of the reach of unauthorized persons.Avoid breathing of the vapors or repeated contact of ether with skin.Do not store cylinders in direct sunlight.Do not puncture or burn cylinders.Discard cylinders in a safe place.
Do not use excessive starting fluid during starting or after the engine is running. Engine damage can result. Do not crank the engine for more than 30 seconds. Allow 2 minutes for the starter to cool before cranking again.
Turn the battery disconnect switch (if equipped) OFF after the engine is stopped to prevent battery discharge, while starter motor is cooling.1. Repeat steps 1 through 4 in the "Above 0°C (32°F)" procedure.2. Try to start engine without ether. If it does not start, then use ether.3. While cranking the engine, spray starting fluid (ether) sparingly, into the engine air inlet or push the starting aid control switch and hold for three seconds (time required to fill chamber). Ether is injected when aid switch is released.Use additional starting fluid once every two seconds until engine runs smoothly.If oil pressure does not register within 15 seconds, stop the engine immediately to prevent damage.4. 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.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.Temperatures below -23°C (-10°F), consult your Caterpillar dealer or refer to the "Cold Weather Operation Guide," Form SEBU5338, available from your Caterpillar dealer.
