Battery Specific Gravity
1. Measure the specific gravity of the electrolyte in each cell with a
hydrometer.
2. If the electrolyte temperature is different from the one that the
hydrometer calibrated, correct the specific gravity
measurement. Use the formula below in (Reference).
3. If the specific gravity is less than 1.215 (after it is corrected for
temperature), charge or replace the battery.
4. If the specific gravity is different between 2 cells by more than
0.05, replace the battery.
• Hold the hydrometer tube vertically but do not remove it
from the electrolyte.
• Do not put too much electrolyte into the tube.
• Let the float move freely and hold the hydrometer at eye
level.
• You must read the hydrometer at the highest electrolyte
level.
(Reference)
• The specific gravity changes with temperature.
To be accurate, the specific gravity
decreases by 0.0007 when temperature increases by 1 °C
(decreases by 0.0004 when temperature increases by 1 °F),
increases by 0.0007 when temperature decreases by 1 °C
(increases by 0.0004 when temperature decreases by 1 °F).
Thus, if you refer to 20 °C (68 °F), correct the specific gravity
reading by the formula below :
– Specific gravity at 20 °C = Measured value + 0.0007 ×
(electrolyte temperature −20 °C)
– Specific gravity at 68 °F = Measured value + 0.0004 ×
(electrolyte temperature −68 °F)
At an electrolyte temperature of 20 °C (68 °F)

Replacement of Air Cleaner Element
1. Remove used air cleaner element.
2. Replace it with a new one.
• The air cleaner uses a dry element. Do not apply oil to it.
• Do not operate the engine without the filter element.
