Operation BS 50-2
4.2 Recommended Fuel
Overview
This rammer engine does not have a separate lubrication system. Instead, it
requires a two-cycle gasoline/oil mixture. Two-cycle oil must be mixed with the
gasoline so that the engine is lubricated as it burns fuel.
NOTICE: Use only the recommended gasoline/oil mixture to fuel this machine.
Using gasoline alone will severely damage the engine.
Requirements
Use only Wacker Neuson two-cycle or other fully synthetic oil meeting the
NMMA TC-W3, JASO FD, or ISO-L-EGD specification.
A gasoline/oil ratio in a range from 50:1 to 100:1 can be used. For optimum
engine performance and durability, a 100:1 ratio with a fully synthetic oil meeting
the specification described above is preferred.
Mix regular unleaded gasoline and two-cycle motor oil in a separate container
before filling the tank.
Refer to the chart below for the proper quantities to use when mixing gasoline
and oil.
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 and
provinces require this information to be posted on the fuel pump.
The following is the Wacker Neuson approved percentage 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.
