Checking The Spark Plug; Suction Head In The Fuel Tank - Dolmar Ms-252 Originalbetriebsanleitung

Checking the spark plug

– Only use the supplied universal wrench to remove or to install the spark plug.
– The gap between the two electrodes of the spark plug should be 0.6
(0.024" – 0.028"). If the gap is too wide or too narrow, adjust it. If the spark plug is
clogged with carton or fouled, clean it thoroughly or replace it.
CAUTION: Never touch the spark plug connector while the engine is running (danger
of high voltage electric shock).
Supply of grease to gear case
– Supply grease (Shell Alvania 3 or equivalent) to the gear case through the grease
hole every 30 hours. (Genuine DOLMAR grease may be purchased from your
DOLMAR dealer.)

Suction head in the fuel tank

– The fuel filler (5) of the suction head is used to filler the fuel required by the
carburetor.
– A periodical visual inspection of the fuel filter is to be conducted. For that purpose
open the tank cap, use a wire hook and pull out the suction head through the tank
opening. Filters found to have hardened, been polluted or clogged up are to be
replaced.
– Insufficient fuel supply can result in the admissible maximum speed being
exceeded. It is therefore important to replace the fuel filter at least quarterly to
ensure satisfactory fuel supply to the carburetor.

suitable tool.
