SAFETY PRECAUTIONS
WARNING
•Have qualified personnel do all maintenance and troubleshooting work.
•Turn the engine off before working inside the machine or servicing the engine.
•Remove guards only when necessary to perform maintenance and replace them when the mainte-
nance requiring their removal is complete. If guards are missing from the machine, obtain replacements from a
Lincoln Distributor. (See Operating Manual Parts List.)
•Read the Safety Precautions in the front of this manual and in the Engine Owner’s Manual before working on this machine.
•Keep all equipment safety guards, covers, and devices in position and in good repair. Keep hands, hair, clothing, and tools away from the 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.
