Failure to properly service the batteries may cause peronal 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 the battery negative (−) to battery negative (−).
Jump start only with an energy source with the same voltage as the stalled machine.
Turn off all lights and accessories on the stalled machine. Otherwise, they will operate when the energy source is connected.
When jump starting the engine with another machine, make sure that the machines do not touch. This could prevent damage to 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 thought to be unusable are still rechargeable.
Use only equal voltage for starting. Check the battery and starter voltage rating of your machine. Use only the same voltage for jump starting. Use of a welder or higher voltage damages the electrical system.
Refer to Special Instruction, SEHS7633, "Battery Test Procedure" available from your AVSpare dealer, for complete testing and charging information.
- Lower the equipment to the ground. Move all controls to the HOLD position. Move the hydraulic lockout control (lever) to the LOCKED position.
- Turn the start switch on the stalled machine to the OFF position. Turn off all accessories.
- Move the machine that is being used as an electrical source near the stalled machine so that the jump start cables reach the stalled machine. Do not allow the machines to contact each other.
- Stop the engine of the machine that is being used as an electrical source. If you are using an auxiliary power source, turn off the charging system.
- Ensure that battery caps on both machines are tight and correctly placed. Ensure that batteries in the stalled machine are not frozen. Make sure that the batteries have enough electrolyte.
Note: The positive terminal of the 12 volt system of the source and the negative terminal of the 12 volt system of the source must be identified correctly before the jumper cables are connected. The positive terminal of the 12 volt system of the discharged battery must be identified correctly before the jumper cables are connected.

- The positive ends of the jump start cable are red. Connect one positive end of the jump start cable to positive cable terminal (1) of the discharged battery.
Do not allow the positive cable clamps to contact any metal except for the battery terminals.
- Connect the other positive end of the jump start cable to positive cable terminal (2) of the electrical source.
- Connect one negative end of the jump start cable to negative cable terminal (3) of the electrical source.
- Finally, connect the other negative end of the jump start cable to engine block (4) of the stalled machine. Do not connect the jump start cable to the battery post. Do not allow the jump start cables to contact the battery cables, the fuel lines, the hydraulic lines, or any moving parts.
- Start the engine of the machine that is being used as an electrical source or energize the charging system on the auxiliary power source.
- Wait at least two minutes before you attempt to start the stalled machine. This will allow the batteries in the stalled machine to partially charge.
- Attempt to start the stalled engine. See Operation and Maintenance Manual, "Engine Starting" for the correct starting procedure.
- Immediately after you start the stalled engine, disconnect the jump start cables in reverse order.
