15. Care and Service in Cold Weather

15-1-3. Battery
Battery performance deteriorates as the temperature goes
down. When the battery voltage is low, battery electrolyte will
easily freeze. Keep the charging rate close to 100% (full charg-
ing) and keep the battery warm for easy start the next day.
Note :
Measure the specific gravity of the electrolyte to determine
the charge ratio using the conversion table given below.
The specific gravity of the electrolyte varies with its tem-
perature and recharged condition.
15-1-4. Preparing heater
Use the heater in cold weather, if equipped.
1) To use the heater, turn the handle (1) on the thermostat
case of the engine section counterclockwise to open the
valve.
2) Operate the heater switch in the cabin/canopy and send
warm air into the operator’s cabin/canopy.
• When you do not use the heater for a long time during the
off season, turn the handle (1) clockwise to close the valve.
• The battery generates flammable gas and it can
cause a fire and an explosion. Keep sparks or
flames away from the battery.
•
Battery electrolyte contains dilute sulfuric acid which
is a strong acid. To avoid serious injury, do not allow
the electrolyte to contact skin or splash into eyes.
If the electrolyte contacts your skin or gets in your
eyes, flush immediately with large amounts of wa-
ter, and obtain medical treatment at once.
