Maintenance/Repairs
Photo 5-44: Follow battery removal and replacement instructions carefully.
C. Battery Removal
and Replacement
WARNING
When removing the battery,
always disconnect the nega-
tive (-) cable first followed by
the positive
(+)
cable. Re-
verse this procedure when re-
installing the battery.
(A, Photo 5-44) and bend the cable
away from all metal parts.
2. Disconnect the negative cable
from the negative (-) battery post
(B, Photo 5-44), and remove cable.
3. Disconnect positive (+) cable
from positive battery post (C,
Photo 5-44) and bend it safely
away from metal parts. Cover
cable terminal with rubber boot.
4. Remove the battery holddown
clamp and remove the battery.
5. Reverse the previous steps to
replace the battery. The battery
posts must face the rear of the
tiller. (The positive post must be
on the left side as you face forward
from the handlebars.)
6. Insert the vent tube (on positive
side of battery) into the vent tube
shield. Be sure it is not crimped,
pinched or folded along its length.
WARNING
To help avoid personal injury,
stop the engine, wait for all
moving parts to come to a
complete stop, remove the
electric start key, disconnect
the spark plug wire and move
wire away from spark plug,
and let the engine and muf-
fler cool before removing or
replacing the battery.
7. Replace the filler caps and wash
off any spilled electrolyte with a
baking soda and water solution.
8. Store the battery in a cool, dry
location. Avoid freezing tempera-
tures. Batteries lose voltage when
in storage, more so in hot weather
than in cold. Ideal storage temper-
ature is 50°P'
necessary to adjust level to the cor-
rect height. Then reconnect the
charger cables to the battery and
charge the battery for one more
hour.
1. Disconnect the negative (-)
cable from the grounding screw on
the right side of the battery bracket
CAUTION
Do not charge the battery at a
rate higher than 12 amperes.
A charge rate greater than
this generates excessive heat
and gassing, and will perma-
nently damage the battery.
6. When battery is fully charged,
tum charging equipment off and
disconnect the cables. Check elec-
trolyte level in all cells. Add dis-
tilled or demineralized water if
1. Remove the battery from the
tiller (see "Battery Removal" in-
structions on this page) and place
on a stable, level surface.
2. Clean the battery if needed. If
the battery is very cold, let it warm
up to between 60-to-80°P'
3. Remove filler caps. Keep them
off when filling and charging.
4. Carefully check the electrolyte
level. If low, add distilled or dem-
ineralized water (do not add bat-
tery acid) to bring the solution
level in each cell up to the correct
height. Avoid overfilling.
5. Charge the battery (with caps
removed) until all cells are gassing
freely. (To check for gassing, wear
protective goggles and inspect
each cell with a flashlight for bub-
bling of the electrolyte solution.)
Use one of the following methods
to charge the battery:
a) Recommended Method: charge
the battery at a rate of I-to-2
amperes until cells are gassing
freely. Do not exceed 24 hours
charging time.
b) First Alternative Method: charge
battery at 4-to-6 amperes until
cells gas freely. Do not exceed
8 hours charging time.
c) Second Alternative Method:
charge the battery at a rate of 6-
to-12 amperes until cells gas
freely. Do not exceed 4 hours
charging time.
