SAFETY PRECAUTIONS

WARNING

•Have qualified personnel do all maintenance and troubleshooting work.

•Turn the engine off before working inside the machine.

•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, get replace- ments from a Lincoln Distributor. See the EXPLOD- ED VIEW AND PARTS LIST at the back of this man- ual.

Read the Safety Precautions in the front of this manu- al and in the Briggs & Stratton Operating and Maintenance Instructions manual before working on the POWER-ARC 4000.

Keep all equipment safety guards, covers, and devices in position and in good repair. Keep your hands, hair, clothing, and tools away from the recoil housing, fans, and all other moving parts when start- ing, operating, or repairing this machine.

ROUTINE AND PERIODIC

MAINTENANCE

ENGINE MAINTENANCE

CAUTION

To prevent the engine from accidentally starting, dis- connect the spark plug lead before servicing the engine.

See Table D.1 for a summary of maintenance intervals for the items listed below. Follow either the hourly or the calendar intervals, whichever come first. More fre- quent service may be required, depending on your specific application and operating conditions. Table D.2 shows engine maintenance replacement parts and numbers.

OIL: Check the oil level after every 5 hours of operation or daily. BE SURE TO MAINTAIN THE OIL LEVEL.

Change the oil the first time after 5 hours of operation. Then, under normal operating conditions, change the oil after every 50 hours or once a year, whichever occurs first. If the engine is operat- ed under heavy load or in high ambient temperatures, change the oil every 25 hours.

Drain the oil from the drain plug located on either side of the engine bottom, as shown in Figure D.1. Refill through the oil fill plug until the oil reaches the top of the fill hole. Use SAE 10W-30 grade oil.
