MAINTENANCE
Before cleaning or inspecting make certain all moving parts have stopped. Disconnect the spark plug wire and keep the
wire away from the plug to prevent accidental starting. Do not put hands, feet, tools or other objects near rotating parts.
Always wear eye protection.
1. CHANGE ENGINE OIL after rst ve hours of operation. Thereafter, change oil every 25 hours of
operation. Use 4-stroke automotive detergent oil SAE 10W-30 .
2. SERVICE AIR CLEANER. Clean and re-oil the pre-cleaner at three month intervals, or every 25 hours,
whichever occurs rst. Remove paper cartridge yearly, or every 100 hours, whichever occurs rst and
clean by tapping gently on a at surface. Replace if very dirty. Keep hands and face away from the
carburetor when the air cleaner is removed. A sudden backre can cause serious burns.
3. SPARK PLUG. Clean and reset gap to .030” every 100 hours of operation.
4. FUEL. Every 250 hours replace the in-line fuel lter or clean the screen and bowl.
5. REMOVE DUST AND DEBRIS DEPOSITS from cylinder head and cylinder head shield every 100 to
300 hours of operation.
6. CHECK GUARDS. Operate the power supply only with the guards and shields in place and working
correctly. If rotating parts are left exposed they are hazardous.
7. MUFFLER. Inspect periodically and replace if necessary. Do not operate the power supply without a
mufer. Inspect spark arrestor screen every 50 hours and replace if damaged.
8. INSPECT GENERATOR BRUSHES after every 100 hours of operation and replace when worn to 3/8
inch (1cm) or less. To inspect brushes, remove brush holder caps, lift brushes out gently and inspect for
wear or breaks in the brush shunts. Replace brushes in the same position. Always replace brushes in sets.
9.CLEAN COLLECTOR RINGS at the same time the brushes are inspected, or after unit has been out of
service for a period of time. Consult your generator’s OEM manual for proper cleaning procedures.
