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 at an angle, the effective fuel capaci- ty will be slightly less than the specified 10 gallons.
HIGH ALTITUDE OPERATION
If the Weldmark 225 will be consistently operated at altitudes above 5000 ft, 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.
CAUTION
Do not operate a Weldmark 225 with a high alti- tude jet installed at altitudes below 5000 ft. 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. For the Kohler model order kit part no. 2475501.
WARNING
Muffler Relocation Shut off welder and allow muffler to cool before touching muffler.
The Weldmark 225 is shipped with the exhaust com- ing 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 Weldmark 225 without the cover in place will result in a higher noise level and no increase in machine output.)
LOCATION / VENTILATION
The welder should be located to provide an unrestrict- ed flow of clean, cool air to the cooling air inlets and to avoid heated air coming out of the welder recirculating back to the cooling air inlet. Also, locate the welder so that engine exhaust fumes are properly vented to an outside area.
WARNING
• Damage to the fuel tank may cause fire or explosion. Do not drill holes in the WELDMARK 225 base or weld to the WELDMARK 225 base.
