ANGLE OF OPERATION
Internal combustion engines are designed to run in a
level condition which is where the optimum perfor-
mance is achieved. The maximum angle of operation
for the engine is 15 degrees from horizontal in any
direction. If the engine is to be operated at an angle,
provisions must be made for checking and maintain-
ing the oil at the normal (FULL) oil capacity in the
crankcase in a level condition.
When operating the welder at an angle, the effective
fuel capacity will be slightly less than the specified 10
gallons.
HIGH ALTITUDE OPERATION
If the Ranger 9 will be consistently operated at alti-
tudes above 5000ft.(1524m), a carburetor jet
designed for high altitudes should be installed. This
will result in better fuel economy, cleaner exhaust,
and longer spark plug life. It will not give increased
power which is decreased at higher altitudes. Engine
horsepower is reduced by 3.5% per 1000ft.(304.8m)
for altitudes above 377ft.(114.9m).
Do not operate a Ranger 9 with a high altitude jet
installed at altitudes below 5000ft.(1529m). This
will result in the engine running too lean and
result in higher engine operating temperatures
which can shorten engine life.
-----------------------------------------------------------------------
High altitude jet kits are available from the engine
manufacturer. Contact your local Onan, or Kohler
Authorized Dealer.
Muffler Relocation
Shut off welder and allow muffler to cool before
touching muffler.
The Ranger 9 is shipped with the exhaust coming
out on the left side. The exhaust can be changed
to the opposite side by removing the two screws
that hold the exhaust port cover in place and
installing the cover on the opposite side.
(Operating the Ranger 9 without the cover in
place will result in a higher noise level and no
increase in machine output.)
