BATTERY CHARGING
For efficient charging of the batteries we recommend
setting the engine to a minimum of 1,200 rpm when
charging out of gear until the battery/ies are fully
charged.
This also applies for AC generation through an inverter.
Charging below 1,200 rpm risks damage.
ENGINE LUBRICANT
WARNING!
New engines are supplied with the engine lube
oil drained off.
Engine oil: Engine oil quality should have the minimum
properties of the American Petroleum Institute 'API'
classification CF with multi-grade SAE ratings as listed in
the following table.
NB: An acceptable alternative is a mineral based, semi-
synthetic lubricating oil with a content mix no greater
than 30% being synthetic based.
The adjacent table gives grades of oil viscosity required for
various ambient temperature ranges.
