S 07 MAINTENANCE
BATTERIES
CAUTION!
To avoid accidental short circuit, be sure to attach the
positive cable to the positive terminal before the negative
cable is attached to the negative terminal.
Never remove the battery cap while the engine is running.
Keep electrolyte away from eyes, hands and clothes. If
you are spattered with it, wash it away completely with
water immediately.
Keep open sparks and flames away from the battery at
all times. Hydrogen gas mixed with oxygen becomes very
explosive.
IMPORTANT!
If the machine is to be operated for a short time without
battery (using a slave battery for starting), use additional
current (lights) while engine is running and insulate ter-
minal of battery. If this advice is disregarded, damage to
alternator and regulator may result.
Battery Voltage
Stop the engine prior to measure the voltage with a circuit
tester between the battery terminals.
(1) Positive Terminal (2) Negative Terminal
IMPORTANT!
If the battery voltage is less than the factory specifica -
tion, check the battery specific gravity and recharge the
battery.
Specifications
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 electrolyte temperature differs from that at
which the hydrometer was calibrated, correct the specific
gravity reading following the formula mentioned on the
right.
(a) Good - (b) Bad - (c) Bad
IMPORTANT!
If the specific gravity is less than 1.215 (after it is correct -
ed for temperature), charge or replace the battery.
If the specific gravity differs between any two cells by
more than 0.05, replace the battery.
NOTE!
Hold the hydrometer tube vertical without removing it
from the electrolyte. Do not suck too much electrolyte
into the tube.
Allow the float to move freely and hold the hydrometer at
eye level.
