S 07 MAINTENANCE
BATTERIES
CAUTION!
To avoid accidental shorting, be sure to attach the pos-
itive cable to the positive terminal before attaching the
negative cable to the negative terminal.
Never remove the battery cap while the engine is running.
Keep electrolyte away from eyes, hands and clothing. If
splashed, rinse immediately and thoroughly with water.
Keep sparks and flames away from the battery at all
times. Hydrogen gas mixed with oxygen becomes highly
explosive.
IMPORTANT!
If the machine is to be used for a short period of time
without a battery (using a temporary battery for starting),
use extra power (lights) while the engine is running and
isolate the battery terminal. If this advice is not followed,
the alternator and regulator may be damaged.
Battery voltage
• Stop the motor before measuring the voltage with
a circuit tester across the battery terminals.
(1) Positive Terminal (2) Negative Terminal
IMPORTANT!
If the battery voltage is below factory specifications,
check the density and recharge the battery.
Spécifications
Battery Voltage - Factory
Specification
More than 12 V
Battery specific gravity
• Check the specific gravity of the electrolyte in
each cell with a hydrometer.
• When the temperature of the electrolyte differs
from that to which the hydrometer has been cali-
brated, correct the specific gravity reading.
(a) Good - (b) Bad - (c) Bad
IMPORTANT!
If the specific gravity is less than 1.215 (after correction
for temperature), charge or replace the battery.
If the specific gravity differs between two cells by more
than 0.05, replace the battery.
NOTE!
Hold the hydrometer tube vertically without removing it
from the electrolyte. Do not draw too much electrolyte
into the tube.
Allow the float to move freely and hold the hydrometer at
eye level.
The hydrometer reading should be taken at the highest
