Angle of Operation
Engines are designed to run in the level condition which is where the optimum performance 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 maintaining the oil level at the normal (FULL) oil capacity in the crankcase.
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 altitudes above 5,000 feet, 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 1000 feet for altitudes above 377 feet.
High altitude jet kits are available from the engine manufacturer. Order Onan kit part number
CAUTION
Do not operate a Ranger 9 with a high altitude jet installed at an altitude below 5,000 ft. This will result in the engine running too lean and result in higher engine temperatures which can shorten engine life.
Muffler Relocation
WARNING
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 of the machine. 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.)
