MAINTENANCE
Starter Unit
90
Use a brush to keep the cooling vents of the starter assembly free
and clean of debris (Fig. 90).
WARNING: The coil spring is under tension and
could fly apart causing serious injuries. Never try to
disassembly or modify it.
Engine
Clean the cylinder & flywheel fins with compressed air or a brush
periodically (Fig. 91). Dangerous overheating of engine may occur
91
due to impurities on the cylinder.
WARNING: Never run the saw without all the parts,
including the drivecase cover and starting housing,
securely in place.
Because parts can fracture and pose a danger of
thrown objects, leave repairs to the flywheel and
clutch to trained Servicing Dealers.
Spark Plug
This engine uses a NGK CMR7A with .02" (0.5 mm) electrode gap
(Fig. 92). Use an exact replacement and replace every six months
or more frequently, if necessary.
WARNING: Never test the ignition system with
ignition wire connector removed from spark plug or
with unseated spark plug, since uncontained
sparking may cause a fire. A loose connection
between spark plug terminal and ignition wire
connector in the boot may create arcing that could
ignite combustible fumes and cause a fire.
92
Use only resistor type spark plugs of the approved range.
Factors such as:
- too much oil in fuel mix;
- dirty air filter;
- unfavourable running conditions, e.g. operating at part load;
may result in rapid deterioration of the spark plug.
Spark Arresting Muffler
The chainsaw is provided with a Spark Arrester System p.n.
Emak 50230157 complying with the requirements of SAE J335
93
standard; you can check the p.n. of the Spark Arrester System on
the muffler itself.
WARNING: A faulty or altered spark arrester system
screen can create a fire hazard.
Through normal use the screen can become dirty and should be
inspected weekly and cleaned as required.
To clean:
• Allow the muffler to cool.
• Remove the three (3) protection screws (B, Fig. 93).
• Remove the protection (C).
• Remove the spark arrester screen screw (D).
• Remove the spark arrester screen (A) p.n. 8850230152.
