3. ENGINE OIL
Engine oil viscosity largely affects engine startability, so the use of lubricant
with selected viscosity according to the atmospheric temperature is
important. (Refer to 3.2 LUBRICANT.)
At low atmospheric temperature, engine oil viscosity will increase to cause
hard engine starting.
4. BATTERY
1) Always pay attention to charging the batteries completely in cold
season.
As the discharge current from the battery is large in cold engine
starting, it takes a comparatively long while to recharge the batteries
than the recharge after the normal engine starting.
Particularly, as the gravity of the insufficiently charged battery’s
electrolyte is low, it will easily be frozen.
Pay attention to keep the batteries warm in the cold season.
2) To replenish the battery with distilled water, do it immediately before
the engine operation.
CAUTION:
If the work is done after the engine has already been in an
operation, the distilled water replenished will not be mixed with
the original electrolyte, allowing the danger of freezing not
mixed distilled water staying in the battery cell upper part.
