Danger:
Read General Safety Precautions Nos. 9 and 10.
1. Battery: The battery is located beneath the
operator’s seat. Remove the fillcaps and check
the level of the liquid electrolyte 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 bat-
tery clean, brush on a strong solution of bicar-
bonate of soda and water and rinse with clean
water. Keep the contacts and cable ends clean
with a wire brush and make sure the connec-
tions are tight. Coat the terminals with petro-
leum jelly to prevent corrosion.
2. Battery Storage: When storing the Mower for
long periods of time the following guidelines
should be taken.
a. Disconnect the battery cables from the ter-
minals and remove the battery. You will have
to remove the control panel to access the
battery strap. Replace control panel.
b. Clean the battery before storing. A dirty bat-
tery will lose its charge over time.
