Operations
Fuel Requirements
Use unleaded gasoline ONLY. DO NOT use any
gasoline additives. We recommend the use of clean,
fresh, unleaded gasoline intended for automotive use.
High octane gasoline should NOT be used with the
engine on this unit. These engines are NOT designed
to use E-85 or Flex Fuels.
Engine Oil Requirements
Use high quality detergent 10W-30 oil of at least API
(American Petroleum Institute) service class SG, SH,
SJ or higher.
NOTE: Using a lower service class oil or extending oil
change intervals longer than recommended can
cause engine damage.
NOTE: Synthetic oils meeting the listed
classifications may be used with oil changes
performed at recommended intervals. However to
allow piston rings to properly seat, a new or rebuilt
engine should be operated for at least 50 hours using
standard petroleum based oil before switching to
synthetic oil.
Altitude Requirements
Engines perform differently with increases/decreases in
altitude. Be sure to check engine speeds during initial
installation. See engine speeds in Technical Specifica-
tions section.
NOTE: To ensure correct engine operation at
altitudes above 1525 meters (5000 ft.), it may be
necessary to have an authorized dealer install a
special high altitude jet kit in the carburetor. If a high
altitude kit has been installed, the engine must be
reconverted to the original jet size, before it is
operated at lower altitudes, or overheating and
engine damage can result.
Chemical Requirements
This cleaning unit, due to its chemical injection pump
design, can be used with a variety of water-diluted
chemical compounds (either acidic or alkaline),
depending on the job to be done. However, to obtain
optimum results with this unit, we recommend using the
PROCHEM line of chemicals. For information on using
the cleaning compounds, refer to the chemical manual.
