Genset Engine Starting With Jump Start Cables; Use Of Jump Start Cables - Vanguard CPW 125-4-S Series Operation And Maintenance Manual

Note: Never hold the Ether Starting Aid button in for more than five seconds.
Note: Use the Ether Starting aid during start-up while cranking the engine only, do not push the button once the engine is
running. Significant damage to the engine could occur if the button is pushed while the engine is running.
Note: Refer to the Ether Starting Aid Cylinder – Replace section of this manual in order to change the ether starting aid
cylinder.
4. Release the Stop/Run/Start switch after the engine starts.

Genset Engine Starting with Jump Start Cables

Warning! Explosion Hazard! Batteries give off flammable fumes that can explode resulting in personal injury.
Prevent sparks near the batteries; they could cause vapors to explode. Do not allow the jump start cable ends to
contact each other or the machine.
Do not smoke when checking battery electrolyte levels.
Electrolyte is an acid and can cause personal injury if it contacts skin or eyes.
Always wear eye protection when starting a machine with jump start cables.
Improper jump start procedures can cause an explosion resulting in personal injury.
Always connect the battery positive (+) to battery positive (+), and battery negative (—) to battery negative (—).
Jump start only with an energy source with the same voltage as the stalled machine.
When starting from another machine, make sure that the machines do not touch. This could prevent damage to the engine
bearings and electrical circuits.
Severely discharged maintenance free batteries do not fully recharge from the alternator after jump starting. The batteries
must be charged to proper voltage with a battery charger. Many batteries though to be unusable are still rechargeable.
This machine has a 24 volt starting system. Use only the same voltage for jump starting. Use of a welder or higher voltage
damages the electrical system.

Use of Jump Start Cables

1. Determine the failure of the engine to start.
2. On a stalled machine, turn the Stop/Run/Start switch (Starter Switch) to the stop position. Turn off any accessories.
3. On a stalled machine, turn on the battery disconnect switch.
4. Move the machines together in order for the cables to reach. DO NOT ALLOW THE MACHINES TO CONTACT.
5. Stop the engine on the machine that is the electrical source. When you use an auxiliary power source, turn off the
charging system.
6. The batteries on this machine are located inside the genset enclosure, on the turbo-side (starter-side) of the engine, and
are accessible via the genset service-panel on the inner deck-side of the enclosure.
7. Check the battery caps for correct placement and for correct tightness. Make these checks on both machines. Make sure
the batteries in the stalled machine are not frozen. Check the batteries for low electrolyte.
8. Connect the positive jump start cable to the positive cable terminal of the discharged battery.
9. Batteries in series may be in separate compartments. Use the terminal that is connected to the starter solenoid. Trace this
cable in order to make sure that the cable is connected to the starter.
10. Connect the positive jump start cable to the positive terminal of the electrical source. Use the procedure from step9 in
order to determine the correct terminal.
11. Connect one end of the negative jump start cable to the negative terminal of the electrical source.
12. Make the final connection. Connect the negative cable to the frame of the stalled machine. Make this connection away
from the battery, the fuel, the hydraulic lines, or moving parts.
