SAFETY PRECAUTIONS

WARNING

Have qualified personnel do the maintenance work. Turn the engine off before working inside the machine. In some cases, it may be necessary to remove safety guards to perform required maintenance. Remove guards only when necessary and replace them when the mainte- nance requiring their removal is complete. Always use the greatest care when working near moving parts.

Do not put your hands near the engine cooling blower fan. If a problem cannot be corrected by following the instructions, take the machine to the nearest Lincoln Field Service Shop.

See additional warning information throughout this operator’s manual and the Engine manual as well.

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

Read the Safety Precautions in the front of this manual and the engine instruction manual before working on this machine.

Keep all equipment safety guards, covers, and devices in position and in good repair. Keep hands, hair, cloth- ing, and tools away from gears, fans, and all other moving parts when starting, operating, or repairing the equipment.

Routine Maintenance

•At the end of each day’s use, refill the fuel tank to minimize moisture condensation in the tank. Running out of fuel tends to draw dirt into the fuel system. Also, check the crankcase oil level and add oil if indicated.

The above schedule is for normal operating condi- tions. More frequent oil changes are required with dusty, high temperature and other severe operating conditions. Refer to the maintenance section of the Engine Owner's Manual for more information.

NOTE: Engine life will be reduced if the oil and oil filter are not changed according to the manufacturer’s recommendation.

ENGINE OIL CHANGE

Drain the oil while the engine is warm to assure rapid and complete draining.

•Remove the oil filler cap and dipstick. Remove the yellow cap from the oil drain valve and attach the flexible drain tube supplied with the machine. Push in and twist the drain valve counterclockwise. Pull the valve out and drain the oil into a suitable contain- er.

•Close the drain valve by pushing in and twisting clockwise. Replace the yellow cap.

•Refill to the upper limit mark on the dipstick with the recommended oil. Tighten the oil filler cap securely.
