.
The fluid level in the
expansion tank must be maintained at 1/2” to 1”
above the bottom of the tank. See Figure 9.

Battery:
The battery is located beneath the
operator’s seat. If so equipped, remove the
fillcaps and check the level of the liquid elec
-
trolyte in the battery every 50 operating hours.
If the level in any of the six cells has dropped
below the bottom of the split ring inside the fill
hole, refill the cell with distilled water. To keep
the outside of the battery clean, brush on a
strong solution of bicarbonate of soda and
water and rinse with clean water. Keep the
contacts and cable ends clean with a wire
brush and make sure the connections are
tight. Coat the terminals with petroleum jelly
to prevent corrosion.

When removing the cables from the battery
follow these steps to avoid a short between
the wrench and the frame.
a. Remove the negative (black) cable.
b. Remove the positive (red) cable.
