WELDING OUTPUT CAbLES

With the engine off, connect the electrode and work cables to the studs provided. These connections should be checked periodically and tightened if neces- sary. Loose connections will result in overheating of the output studs.

When welding at a considerable distance from the welder, be sure you use ample size welding cables. Listed below are copper cable sizes recommended for the rated current and duty cycle. Lengths stipulated are the distance from the welder to work and back to the welder again. Cable sizes are increased for greater lengths primarily for the purpose of minimizing cable voltage drop.

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 capacity will be slightly less than the specified 12 Gal. (45 L).

LIFTING

The Ranger® 250 GXT weighs approximately 685lbs.(411kg) with a full tank of gasoline. A lift bail is mounted to the machine and should always be used when lifting the machine.

ADDITIONAL SAFETY PRECAUTION

WARNING

 

• Lift only with equipment of

 

adequate lifting capacity.

 

• be sure machine is stable

 

when lifting.

 

• Do not lift this machine using

 

lift bail if it is equipped with a

 

heavy accessory such as trail-

 

er or gas cylinder.

FALLING

• Do not lift machine if lift bail is

cause injury.

• Do not operate machine while

 

suspended from lift bail.

------------------------------------------------------------------------

HIGH ALTITUDE OPERATION

At higher altitudes, Welder output de-rating may be necessary. For maximum rating, de-rate the welder output 3.5% for every 1000 ft. (305m) above 3000 ft. (914m). If operation will consistently be at altitudes above 5,000 ft. (1525m), 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. Contact your local authorized engine service shop for high altitude jet kits that are available from the engine manufacturer.

CAUTION

Do not operate with a high altitude 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.

------------------------------------------------------------------------

MUFFLER OUTLET PIPE

Using the clamp provided secure the outlet pipe to the outlet tube with the pipe positioned such that it will direct the exhaust in the desired direction. Tighten using a 9/16” socket or wrench.
