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 first five 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 first. Remove paper
cartridge yearly, or every 100 hours, whichever
occurs first and clean by tapping gently on a
flat surface. Replace if very dirty. Keep hands
and face away from the carburetor when the
air cleaner is removed. A sudden backfire 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
filter 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 muffler. 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.
