Checking the Spark Plug
N Clean dirty spark plug.
N Check electrode gap (A) and
readjust if necessary – see chapter
"Specifications."
N Use only resistor type spark plugs of
the approved range.
Rectify problems which have caused
fouling of spark plug:
– too much oil in fuel mix,
– dirty air filter,
– unfavorable running conditions, e.g.
operating at part load.
WARNING
To reduce the risk of fire and burn injury,
use only spark plugs authorized by
STIHL. Always press spark plug boot (1)
snugly onto spark plug terminal (2) of the
proper size. (Note: If terminal has
detachable SAE adapter nut, it must be
securely attached.) A loose connection
between spark plug boot and ignition
wire connector in the boot may create
arcing that could ignite combustible
fumes and cause a fire.
Installing the spark plug
N Screw home the spark plug, fit the
boot and press it down firmly.
Use STIHL gear lubricant (special
accessory) for lubrication.
N Check grease level about every 100
hours of operation.
N Unscrew the filler plug (1). If no
grease can be seen on the inside of
the filler plug, screw the tube of
lubricant (2) into the filler hole.
N Squeeze up to 1/5 oz (5 g) grease
into the gearbox.
NOTICE
Do not completely fill the gearbox with
grease.
N Refit the filler plug and tighten it
down firmly.
