Warning: Before cleaning, inspecting, or repairing the unit, make sure that the
engine has stopped and is cool.
9.1 Blade lubrication
Warning: before lubricating, be sure your unit is switched off and that the
blade has come to a complete stop.
▪ For easier operation and longer blade life, lubricate the blade before and after each use.
Apply light machine oil along the edge of the blade bar
9.2 Safety lock (Fig. 8)
Warning: Stop using the trimmer if the safety lock is defective
Safety lock is the device which stops the throttle lever from being activated unintentionally. If
you push the safety lock, you will activate the throttle lever.
Safety lock:
▪ Check that the throttle lever does not move if you do not push the safety lock.
▪ Check that the throttle lever moves if you activate or release it while pushing the safety
lock.
▪ Check that the safety lock returns to its original position if you take your hand from safety
lock.
▪ If these checks reveal any defects, contact your nearest dealer and ask to have them
repaired
9.3 Air cleaner (Fig. 9)
Release the air cleaner cover and remove the dust. If the element is dirty, clean it by tapping it
or by blowing away the dirt. If the element is bent or damaged, replace it. After you have
cleaned the element reattach it to the cleaner body with the stamp on the outside (facing the
cleaner cover). After that, replace the cleaner cover
Important: a clogged air cleaner reduces engine performance. Operating with no element or
with a bent or damaged element causes irregular wear and tear of the engine mechanism
9.4 Air cooling
This engine is air-cooled. Dust clogging up the air cooling inlet port and the cylinder fins will
cause the engine to overheat. Periodically check and clean the cylinder fins after removing
the air cleaner and the cylinder cover.
9.5 Spark Plug (Fig. 10)
Starting problems and misfiring are often caused by a fouled sparkplug
Periodically clean the spark plug, and replace with a new one as and when required.
