4. Spark Plug

Spark plug type: BP6ES, BPR6ES (NGK) or NHSPLD F6RTCU

Proper spark plug clearance will avoid spark plug deposits and wear.

a) Remove the spark plug using the included

spark plug wrench.

b) Clean the spark plug with a steel brush. If the

insulator is damaged, replace the spark plug.

c) Measure the spark plug clearance with a feeler.

The clearance should be 0.7-0.8mm. If adjustment

is necessary, bend the side electrode carefully.

d) Check that spark plug gasket is in good condition,

or replace with a new one. Install the spark plug

first by hand and then tighten it using a spark plug

wrench. If a new spark plug is used, twist ½ turn

after impacting the gasket; if reinstall the

original one, just twist 1/8-1/4 turn more.

CAUTION

● The spark plug must be tightened securely, or it may become very hot and damage the engine.

● Only use listed spark plug or equiv. Incorrect spark plug heat range may damage the engine.

WARNING

Be careful not to touch the muffler

during or just after running the engine.
