GENERAL MAINTENANCE
Keep the generator in a clean and dry environment
where it is not exposed to dust, dirt, moisture, or
corrosive vapours.
Do not allow the cooling air slots in the generator to
become clogged with foreign material such as
leaves, snow, etc.
Do not use a garden hose to clean the generator.
Water entering the fuel system or other internal
parts of the unit can cause problems that will
decrease the life of the generator.
To clean the unit:
1. Use a soft bristle brush and/or vacuum cleaner
to loosen and remove dirt and debris.
2. Clean air vents with low pressure air that does
not exceed 25 psi.
3. Wipe the exterior surfaces of the generator with
a damp cloth.
SPARK PLUG MAINTENANCE
To ensure proper engine operation, the spark plug
must be properly gapped and free of deposits.
Remove the 4 access panel screws with a
screwdriver and then remove panel, Fig.15.

Pull the HT lead off the spark plug, Fig 16, and
clean any dirt from around the spark plug base.
Using the spark plug socket supplied remove the
spark plug, Fig 17.
Inspect spark plug for damage, and clean with a
wire brush before reinstalling. If insulator is cracked
or chipped, spark plug should be replaced. Make
sure electrode gap is 0.60mm-0.80mm.
NOTE: If replacing, use the following
recommended spark plug: ER6C.
MAINTENANCE
Screw spark plug back by hand, avoid damaging
threads of the cylinder.
Put the spark plug back in position and use the
spark plug wrench to tighten it. If spark plug is new,
use 1/2 turn to compress washer appropriate
amount. If reusing old spark plug, use 1/8 to 1/4
turn for proper washer compression.
Replace spark plug cap.
Reinstall the spark plug maintenance cover and se-
cure with the 4 screws.
Warning! Spark plug must be assembled firmly, or
it will become hot and may damage generator.
A loose spark plug can overheat and damage the
engine.
CLEANING THE EXHAUST PORT & MUFFLER
Depending on the type of fuel used, the type and
amount of oil used, and/or your operating
conditions, the exhaust port and muffler may
become blocked with carbon deposits. If you notice
a power loss with your petrol-powered tool, you
may need to remove these deposits to restore
performance. We highly recommend that only
qualified service technicians perform this service.
