8 -1 Handling in winter
(541A-0063-1E)
If the outside temperature drops to
−
5
°
C or below, problems can occur such as a difficulty in starting the engine, poor
lubrication, abnormal noise from the pump etc. In areas where the temperature could fall to the − 15 ° C ― − 20 ° C range,
the fuel and engine oil must be changed. In areas which can get as cold as
−
20
°
C or below, adjust the concentration of
Long Life Coolant before the onset of winter. If you are working at temperatures of − 15 ° C or below, contact your
authorised KATO dealer.
(1) Fuel
For fuel, use diesel fuel with a fluidity point at least − 5 ° C below the minimum outside air temperature. For
example, if the outside air temperature falls to
−
15
°
C, use an oil which remains fluid at
−
20
°
C.
Use of a non-recommended fuel will reduce performance and could cause a major accident.
Such problems are not subject to guarantee.
(541A-0065-1E)
(2) Engine oil
Use engine oil with an API service classification of CD
or higher. Engine oil becomes more fluid at higher
temperatures and more viscous at lower temperatures,
so the viscosity of the oil must suit the temperature.
Particularly in winter, using oil of the wrong viscosity
can make it difficult to start the engine.
