5. Inspect spark plug for damage, and clean with a wire
brush before reinstalling. If insulator is cracked or chipped,
spark plug should be replaced.
6. Measure plug gap. The correct gap is 0.020 – 0.028 in. (0.5
- 0.7 mm). To widen gap, if necessary, carefully bend the
ground (top) electrode. To lessen gap, gently tap ground
electrode on a hard surface.
7. Seat spark plug in position; thread in by hand to prevent
cross-threading.
8. Secure the spark plug with wrench. Do not over-tighten,
replace the spark plug cap.
NOTE: An improperly tightened spark plug will become
very hot and could damage the engine.

2. Allow 30 minutes of "cool down" time before transporting
the machine. Make sure engine and exhaust of unit are
cool.
3. Pull the lock pin ring to unlock the handle, and turn the
handle up to the transporting position.
4. Tilt the machine until it balances on the wheels, then roll
the machine to the desired location.
5. If transporting in a vehicle, securely restrain the generator.
6. If the generator need to be lifted, fold the handle to the

people to lift. To avoid back injury, keep your knees bent
and lift with your legs, not your back, and get help when
needed.
