4.2 Application

This machine is designed for compaction of sand, gravel, soil and
asphalt. The RS 800 has tight clearances, making it ideally suited for
small repairs and maintenance of roads, walks, bridges, and parking
lots. The high exciter forces ensure excellent compaction of cohesive­type soils, as well as loose soils and gravel. The sprinkler system and
water control valve allow the roller to be used wet or dry.

4.3 Recommended Fuel (RS 800A, RSS 800A)

The engine requires regular grade unleaded gasoline. Use only fresh,
clean gasoline. Gasoline containing water or dirt will damage fuel
system. Consult engine owner’s manual for complete fuel
specifications.

Use of oxygenated fuels

Some conventional gasolines are blended with alcohol. These

gasolines are collectively referred to as oxygenated fuels. If you use
an oxygenated fuel, be sure it is unleaded and meets the minimum
octane rating requirement.

Before using an oxygenated fuel, confirm the fuel's contents. Some

states / Provinces require this information to be posted on the fuel
pump.

The following are Wacker Neuson approved percentages of

oxygenates:

ETHANOL - (ethyl or grain alcohol) 10% by volume. You may use

gasoline containing up to 10% ethanol by volume (commonly referred
to as E10). Gasoline containing more than 10% ethanol (such as E15,
E20, or E85) may not be used because it could damage the engine.

If you notice any undesirable operating symptoms, try another service

station, or switch to another brand of gasoline.

Fuel system damage or performance problems resulting from the use

of an oxygenated fuel containing more than the percentages of
oxygenates mentioned above are not covered under warranty.
