understand the danger perform inspection or
maintenance.
IMPORTANT
• Do not
disconnect or remove the battery when
you operate engine.
Tools required
• Battery / coolant tester
Zero adjustment
1. Open the cover and drip water on the prism surface
using the included rod.
2. Close the cover.
3. Aim in a direction that is bright, look into the lens,
and adjust the focus until the gradations can be
seen clearly.
4. If the boundary line is not on the gradation baseline
(0 position), turn the adjustment screw until it
matches.
5. When zero adjustment is complete, wipe the prism
and cover surface with a soft cloth or tissue paper.
Measurement of test field
1. Open the cover and drip test fluid on the prism
surface using the included rod.
2. Close the cover.
3. Aim in a direction that is bright, look into the lens
and read the gradation of the blue boundary line.
4. When the measurement is complete, wipe the
prism and cover surface with a soft cloth or tissue
paper.
NOTE
• Electrolyte specific
gravity and amount of
discharge.
Use the following table as a reference.
(A) Electrolyte specific gravity
(B) Discharge
(C)
Good
(D) Charging is necessary.
NOTE
• Temperature
conversion of electrolyte
specific gravity.
• Battery electrolyte specific gravity changes
based on temperature.
• Insert the value identified on a specific
gravity meter into the following conversion
equation for temperature correction to learn
an accurate specific gravity value. (Standard
temperature assumed to be 20 ℃ [68 ℉].)
D20 = Dt +0.0007 (t -20)
D20 = specific gravity value converted to
standard temperature of 20 ℃ (68 ℉)
Dt = measured specific gravity value at the
electrolyte temperature t ℃

CAUTION
• To
prevent an accidental short circuit, attach
the positive cable to the positive terminal before
the negative cable is attached to the negative
terminal.
• Do not remove the battery cap while the engine
operates.
• Keep electrolyte away from eyes, hands and
clothes.
If you are spattered with it, clean with water
immediately.
• Keep open sparks and flames away from the
battery at all times.
Hydrogen gas mixed with oxygen becomes very
explosive.
• Hold the starter to prevent its movement when
you do a test on the motor.
