■ AIR CLEANER
Take off the air-cleaner cover and remove the dust
inside the air cleaner every 25 hours of use.
When the air-cleaner element has become extremely
contaminated, clean it thoroughly with warm water
including a neutral detergent. Install it after drying it
completely.
When the air-cleaner element has become deformed or
damaged, replace it with a new one.

If the air-cleaner element becomes clogged, the output
of the engine decreases and fuel consumption worsens.
If you continue to operate the machine without an air-
cleaner element, or with an air-cleaner element which
has been deformed or damaged, the inside of the
engine will wear severely.

bottom corner is rounded. (MA1)

• Do not cool the blade with water in case of using

grinder. It may cause cracks on blade.

■ REFILLING TRIMMING LINE (MA2)
1. For replacement line, use a diameter of .095in

may cut down the trimming performance. 

2. Pinch the slotted area on the both sides of the spool

housing to unhook the bottom cap.

3. Take out the spool and pull off the old line. Fold new

line so that one half line is 4.7in.(12cm) shorter than
