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.

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

ELECTRIC SHOCK can kill.

• Do not touch electrically live parts or electrode with skin or wet clothing.

Insulate yourself from work and ground

Always wear dry insulating gloves.

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

ENGINE EXHAUST can kill.

• Use in open, well ventilated areas or vent exhaust outside.

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

MOVING PARTS can injure.

Do not operate with doors open or guards off.

• Stop engine before servicing.

Keep away from moving parts.

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

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 mov- ing 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.

 

 

Kohler

 

 

CH23S

 

Oil

100 Hrs.

 

 

 

 

Oil Filter

200 Hrs.

 

 

 

The above schedule is for normal operating conditions. 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 fil- ter are not changed according to the manufac- turer’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 con- tainer.

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.

ENGINE OIL REFILL CAPACITIES

Without oil filter replacement:

• 1.7qt. (1.6 liter)-Kohler

With oil filter replacement:

• 2.0qt. (1.9 liter)-Kohler
