IMPORTANT
- The machine used for jump starting should have a 12 volt battery with at least 500
cold cranking amperes, and a negatively grounded system.
DANGER!
FROZEN BATTERIES CAN EXPLODE and result in death or serious in-
jury. DO NOT charge a frozen battery. Let the battery thaw out before putting on a charger.
UNIT MOVEMENT can result in death or serious injury. NEVER jump-start the machine
with cables directly on the starter motor or solenoid valves The machine could move for-
ward or backward and injure the person jump starting it.
To jump-start with the cables:
1. Ensure battery is not frozen. If the fluid is frozen, remove the battery from unit and allow to thaw
before charging.
2. Connect the positive (+) jumper cable to the positive (+) terminal of the discharged battery.
3. Connect the other end of the same jumper cable to the positive (+) terminal of the booster bat-
tery.
4. Connect one end of the second jumper cable to the negative (-) terminal of the booster battery.
5. Make the final jumper cable connection to the engine block or the furthest ground point away
from the discharged battery.
WARNING!
-
Make sure the cables are clear of any moving engine parts before
starting the engine.
6. Start the engine. If the engine will not start after several tries, the machine or battery may need
servicing.
7. After engine starts, leave cables connected for one to two minutes.
8. Disconnect cables in reverse order.
9. Use the machine normally to charge the battery.
9.3.2 Checking the switches and micro switches function
Switches either open a circuit to stop current flow or close and allow current to flow through.
• A normally open (NO) switch prevents current flow until the switch is switched on, completing
the circuit and allowing current to flow through it.
• A normally closed switch (NC) allows current to flow until the switch is actuated, breaking the
circuit and stopping current flow through it.
To check the operation of a switch or micro switch you must have an Ohmmeter-dependent tester.
