6.8 SPARK PLUG SERVICE
To ensure proper engine operation, the spark plug must be properly gapped and free of deposits.
1. Remove the spark plug
If the engine has been running, the muffler will be very hot. Be careful not to touch the muffler (A).
(Fig. 6-8A)
2. Visually inspect the spark plug. Discard it if the insulator is cracked or chipped. Clean the spark plug
with a wire brush if it is to be reused.
3. Measure the plug gap with a feeler gauge. The gap should be 0.7-0.8mm (0.028-0.031 in). Correct as
necessary be bending the side electrode (Fig 6-8B).

4. Check that the spark plug washer is in good condition, and thread the spark plug in by hand to pre-
vent crossthreading.
5. After the spark plug is seated, tighten with a spark plug wrench to compress the washer.
NOTE: If installing a new spark plug, tighten 1/2 turn after the spark plug seats to compress the washer.
If reinstalling a used spark plug, tighten 1/2-1/4 turn after the spark plug seats to compress the washer
(Fig 6-8C).
The spark plug must be securely tightened. An improperly tightened plug can become very hot and
damage the engine. Never use a spark plug with an improper heat range.

6.9 STORAGE
1. Drain the fuel
a. With the fuel valve in the ON position, remove the carburetor drain screw (B) (side of carburettor
bowl), and drain all the petrol from the fuel tank into a suitable container. (Fig. 6-8D)
b. Reinstall the carburetor drain screw (B) (Fig. 6-8D).
Gasoline is extremely flammable and is explosive under certain conditions. Perform this task in a well
ventilated area. Do not smoke or allow flames or sparks in the area during this procedure.
2. Change the engine oil.
3. Remove the spark plug and pour about a tablespoon of clean engine oil into the cylinder. Crank the
engine several revolutions to distribute the oil, then reinstall the spark plug.
4. Pull the starter rope slowly until resistance is felt. Continue pulling until the notch on the starter pulley
aligns with the hole on the recoil starter (see illustration below). At this point, the intake and exhaust
valves are closed, and this will help to protect the engine from internal corrosion (Fig. 6-8E).
5. Cover the unit to keep out dust.
7. HOW TO USE SPRAY LANCE
The nozzles for the spray wand are stored in nozzle holder on the panel assembly. Colors on the panel
identify nozzle location and spray pattern. See chart to choose the correct nozzle for the job to be
performed.
