1/2019 MC405C-3 5-79
COLD TEMPERATURE
PREPARATION
When the temperature goes down, the machine
starts to have some difficulty in starting. Take the
following actions.
Lubrication
Change the oil to the one with low viscosity. See
For more information on the specified viscosity,
see "LUBRICATING OIL" on page 5-14.
Coolant
WARNING! The antifreezing fluid is
inflammable. Do not put the fluid close to fire
and do not smoke while handling the fluid.
Do not smoke when handling the antifreezing
fluid.
CAUTION: Never use antifreezing fluid with
methanol, ethanol, and propanol.
For more information on the coolant replacement
period and mixing rate of antifreezing fluid, see
"Cleaning Inside Engine Cooling System" on
page 5-74.
Battery
WARNING!
• The battery produces combustible gas and
can be explosive. Do not put fire close to
the battery.
• The battery fluid is a harmful substance.
Keep it away from your eyes and skin.
Should it come into contact with your eye or
skin, wash the affected area with plenty of
water and consult a physician immediately.
The battery capacity drops when the temperature
goes down.
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.
Cautions After Completing the
Operation
Observe the followings to prevent the machine
from not being able to function the next morning
because of deposits such as dirt and water and
materials around the feet frozen.
• Remove the dirt and water on the machine.
Keep the hydraulic cylinder rod surface
especially clean to prevent seal from being
damaged with the dirt coming into the seal
together with the water drops.
• Park the machine on the solid and dry ground.
If there is no such location to park, place a
board on the ground to park the machine on the
board.
This prevents the ground and around the feet of
the machine from freezing and allows the
machine to start travelling next morning.
• Remove the drain plug to drain the water in the
fuel system to prevent the water from freezing.
• The battery ability remarkably drops at low
temperature.
Cover the battery or remove the battery from
the machine and keep it at warm place to be
installed next morning.
After the Cold Weather Is Gone
When the season changed and it started to get
warm, take the following action.
• See "LUBRICATING OIL" on page 5-14 to
change the oil in the system to the one with
specified viscosity.
