925072 Volvo.Penta O-ring

Above -12°C (10°F)
1. Place the transmission or other power takeoff attachments in NEUTRAL.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. Turn the start switch (1) 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.
4. Release the start switch when the engine starts. If oil pressure does not rise within 15 seconds after the engine starts, stop the engine and make necessary corrections.5. Do not apply load to the engine or increase engine speed until oil pressure gauge indicates normal and all temperature gauges reach operating temperature. Check all gauges during the warm-up period.Below -12°C (10°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.2. Turn the start switch 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 Guide," Form SEBU5338, available from your Caterpillar dealer.Starting From External Electrical Source
Always wear protective glasses when working with batteries.Do not allow the free end of booster cables to make contact with each other or touch the engine. This will help prevent sparks near the batteries.Batteries give off flammable fumes that can explode.Do not smoke when observing the battery electrolyte levels.Electrolyte is an acid and can cause personal injury if it contacts skin or eyes.
Be sure the main power switch is in the OFF position before attaching the booster cables to the engine being started.When using booster cables, be sure to connect in parallel: POSITIVE (+) to POSITIVE (+) and NEGATIVE (-) to NEGATIVE (-).Use only equal voltage for boost starting. The use of a welder or higher voltage will damage the electrical system.
Engines without engine-to-frame ground straps can be damaged by electrical discharge.To prevent electrical discharge damage, check to make sure there is an engine-to-frame ground strap. For engines which have the alternator connected to an engine component, the ground strap must connect that component to the frame.Some engines have starter-to-frame ground straps. But, many of these starters are not electrically grounded to the engine. They have electrical insulation systems. For this reason, the starter-to-frame ground strap may not be an acceptable ground.Connect one end of cable to the POSITIVE (+) (ungrounded) terminal of the battery on the engine being started. Connect the other end to the POSITIVE (+) terminal of the power source.Connect one end of the second cable to the NEGATIVE (-) terminal of the power source. Connect the other end to the frame of the engine to be started.Turn the start switch on and start the engine.Disconnect the cable from the frame first. Disconnect the other end from the NEGATIVE (-) terminal of the power source. Disconnect the cable from the POSITIVE (+) terminal of the battery. Disconnect the other end from the POSITIVE (+) terminal of the power source.
