Pre-operational inspection
DANGER
: Personal injury
▪
There are components rotating at high speed in the welder.
▪
Make sure to stop the engine, before starting maintenance and
inspection of the welder.
Personal injury may arise due to roll-in of your hands by rotating
components, if you fail to observe the precautions given above.
Carry out inspection described below prior to operation.
(1) Check of engine oil level
Fully insert the engine oil level gauge, and check if the oil level is within the range of “H”" level and
“L” level on the level gauge. Check the oil for contamination at the same time.
Replenish oil If the oil level is less than the “L” level (lower limit).
[Caution]:The oil level should not be higher than the “H” level (upper limit). Damage to engine
cylinder interior may occur otherwise.
Regarding engine oil
Engine oil exerts major influence over the engine performance, startability, lifetime and others.
Therefore, select engine oil of viscosity that is most appropriate for the atmospheric temperature of
the place of use.
(a) Use engine oil of CC class or higher of API service classification.
(b) Oil for summer (SAE30) is recommended for use in summer, and oil for winter (SAE20) is
recommended for use in winter. In addition, oil for all seasons (SAE10W-30), the viscosity of
which hardly changes by temperature, is recommended for use throughout the year.
Select appropriate engine oil in accordance with the lower right table.
(c) The oil volume required for oil change is as follows.
