7. HANDLING MACHINE IN COLD ENVIRONMENT
7.1 PREPARING FOR LOW TEMPERATURE
In cold conditions, the machine starts to have some difficulty in starting. Take the following
actions.
[1] LUBRICATION
Change the lubricating oil to one with low viscosity.
See “INSPECTION AND MAINTENANCE 6.1 USE OF LUBRICATING OIL ACCORDING TO
TEMPERATURES” for the specified viscosity.
[2] COOLANT
Antifreezing fluid is inflammable. Do not put the fluid close to fire.
Do not smoke when handling antifreeze.
CAUTION
Never use antifreezing fluid with methanol, ethanol, and propanol.
See “INSPECTION AND MAINTENANCE 9.10 EVERY 1000 HOURS MAINTENANCE [1]
CLEANING ENGINE COOLING SYSTEM
” for the coolant replacement period and mixing rate
of the antifreeze fluid.
[3] BATTERY
• The battery produces combustible gas and can be explosive. Do not put fire close to
the battery.
• The battery fluid is a hazardous substance. Keep it away from your eyes and skin.
Should it come into the contact with eyes or skin, wash the affected area with plenty of
water and consult a physician immediately.
The battery capacity drops when the temperature decreases.
In this condition, the battery fluid can freeze with low battery charging rate. Keep the charging
rate as close to as 100%. Keep the battery warm in order to start the engine next morning.
NOTES
Measure the specific gravity of the battery fluid and
convert it into the charging rate using the chart below.
