PRB _ OPERATION INSPECTION
I . ENGINE OIL
CAUTION
O Engine oil is a key f'actor in deciding the engine's performance. Do not apply engine oil with additives or 2
- stroke gasoline engine oil, as they haven's enough lubrication, which may shorten the engine's service life.
O Check the engine with it stopped on a level ground.
SAEI0W - 30 (Fig.2) is recommended for general, all temperature use.
As viscosity varies with regions and temperatures, so the lubricant has
to be selected in accordance with our recomrnendation. If single viscosity
engine oil is to be used instead, its viscosity corresponding to average îsmp.rârurô
temperature of the region must be considered. lrrrrrlr
