ENGINE OIL
Recommendations
Use premium quality motor oil, Class SJ or SL. Look for the SAE
(Society of Automotive Engineers) or API viscosity grade. Referring to
the table below, choose the viscosity grade appropriate for the ambient
temperatures expected during the period of time until the next sched-
uled oil change.
Single-grade SAE 30 oil is preferable when temperatures are 50° and
90°F (10° - 32°C).
If multi-grade oil is used, oil consumption tends to increase if the ambi-
ent temperature is high.
Filling and Change Interval
After the fi rst 20 hours of operation the initial oil and oil fi lter should be
replaced.
Thereafter, change the oil every 100 hours of operation and change
the oil fi lter every 200 hours.
Apply a thin coat of oil to the oil fi lter gasket surface and install by
tightening the oil fi lter about 3/4 turn after the seal has reached the
crankcase surface.
The oil capacity of the crankcase is 1.55L (53 fl .oz.).
When fi lling the crankcase, keep the engine level and fi ll up to the up-
per mark of the oil gauge. Check the oil with the oil gauge pushed all
the way in its seat.
Crankcase pressure can blow hot engine oil out
the fi ll tube causing severe burns. Always stop
the engine before removing the oil fi ll cap or the
oil gauge.

! WARNING
Check the oil level daily, before starting. Keep the oil level between the
upper and lower level on the gauge.
STARTING BATTERIES
An engine equipped with an electric starter requires a properly sized
battery along with appropriately sized interconnecting cables to insure
proper starting. Neither cranking performance or starter service life will
be satisfactory if an undersized battery is used.
Use a battery rated 12V-30 amp or larger.
The customer must supply battery cables. Use the table below to
select the proper cable for the positive side connection.
Connect a ground strap to the negative terminal. Use a fl at strap
25.0mm (0.25”) wide.
