Batteries
CAUTION: Use extreme caution when working with batteries. Sulfuric acid in batteries can cause severe
injury if allowed to contact the skin or eyes.
• Explosive hydrogen gas is vented from the batteries through openings in the battery caps. Do not
smoke while servicing the batteries.
• Remove all jewelry. Wear safety glasses, rubber gloves and a rubber apron
• Do not allow tools to touch more than one battery terminal at a time
• Electrical components in this machine can be severely damaged if the batteries are not installed and
connected properly.
• The batteries are extremely heavy and may require a lifting device or assistance to remove and
replace into the machine.
1. Turn the off the machine and
disconnect the main battery
connector (A).
2. Pull back the insulating boot (B)
and disconnect the main battery
connector’s positive terminal at
(E)
. Do not disconnect at lug (F)
because that secures the 150 amp
fuse.
3. In a similar manner, remove the
main battery connector’s negative
terminal (C). However, there is no fuse at the
negative terminal.
4. Taking care to not short across the battery
terminals, remove each of the interconnecting
cables (H) from the batteries.
5. Make sure the battery straps (D) are not
damaged or cut, and then lift out each of the
batteries from the battery bay.
6. Install the new batteries into the compartment.
Note the orientation of the batteries shown
above.
7. Reconnect the battery cables.
– All cables are connected positive-to-negative for a series connection between all 6 batteries.
– Position the cables so the battery caps can be easily removed for battery service.
– Take care to not over torque the cable connector, as this may damage the battery post.
8. Coat the terminals with spray-on battery terminal coating (available at most auto parts stores).
