OPERATING INSTRUCTIONS
BOOSTER BATTERY CONNECTIONS TO MACHINE BATTERIES (JUMP START) WARNING: Batteries contain acid and explosive gas. Explosion can result
!
from sparks, flames or wrong cable connections. To connect the jumper cables correctly to the battery of this machine, see the correct method shown on this page. Failure to follow these instructions can cause serious injury or death. WARNING: Battery explosion and/or damage to electrical components
!
can result from improper connection of booster batteries or charger. Connect positive to positive and negative to negative. Externally, battery acid can cause burns and blindness, and taken internally it is poison. Turn ignition key to the start position. When the engine starts, release the key. Immediately pull throttle lever into low idle. Then set at one half speed. Maintain one half maximum speed until coolant temperature gauge needle moves from its minimum position.
Two persons are required for this procedure. Make sure the person making the connections is wearing face protection. NOTE: Make sure the batteries are not frozen. Do not use batteries that have been frozen. Replace the batteries if the batteries have been frozen. 1. Open the engine hood. Sit in the operators seat and have the other person make the connections.
NOTE: Do not use the starter for more than 15 seconds without a pause of 30 seconds to allow it to cool down. Observe all instruments for proper reading.
2. Make sure the jumper batteries are 24 volts.
It is extremely important to allow the engine to run for three to five minutes at 1/4 to 1/2 throttle to permit the lubrication oil to warm and circulate freely through the bearings. This procedure is mandatory for cold weather operation.
3. If using another machine for power, make sure the two machines DO NOT touch. 4. Connect the positive (+) jumper cable to the positive (+) battery terminals first. 5. Connect the negative (-) jumper cable to the negative (-) terminal on the jumper batteries on the other machine. Connect the other end of the negative (-) jumper cable to a good frame ground away from the batteries.
Check engine lubricating oil pressure. With engine running at high speed and the coolant at normal operating temperature, oil pressure must be within normal operating range. When the oil is cold no pressure may be indicated on the gauge for several seconds after the engine starts. If the pressure does not rise to normal or above, after a few seconds, the engine must be stopped immediately and the cause determined and corrected. Check the transmission fluid pressure. Within a few seconds after the engine starts the transmission oil pressure gauge must register in or near the green range.
6. Start the engine according to the instructions in this manual. See Starting the Engine Using Booster Batteries, in this manual. 7. Have the other person disconnect the jumper cables in the reverse order that they were connected in. Close the engine hood. Turn master switch key, located in operator’s compartment to the “ON” position. Pull throttle lever back to full speed position if engine is cold (1/4 speed position, if engine is warm). 63
