WARNING
•Make sure that the engine has stopped and is cool before performing any service to the machine. Con- tact with hot muffler may result in a personal injury.
•Do not modify the pump or dismantle the engine.
•When replacing parts please use Zenoah original parts or designated parts.
■Air cleaner
•After every 25 hours of operation, please remove the air cleaner cover and inspect the element. If it is too dirty, wash it carefully in warm water containing a neu- tral detergent, and return it to its original position af- ter drying it thoroughly.
•If the element is distorted or damaged, please replace it with a new one.

IMPORTANT
•If the air cleaner element is blocked, the efficiency of the engine will be reduced. In addition, the engine interior will suffer abnormal wear if operated without the element or if continually operated with a distorted or damaged element fitted.
■Fuel filter
After every 25 hours of operation, empty the fuel tank, detach the fuel filter from the tank, and remove all dirt. If the filter is too clogged, please replace it with a new one.

a. Fuel filter
IMPORTANT
•If the fuel filter is clogged, the engine speed may be limited or speed fluctuations may occur.
•If the engine is operated without a fuel filter, dirt will accumulate in the carburetor and cause it to malfunc- tion.
■Spark plug
WARNING
•Do not touch the spark plug with your bare hands immediately after operation, as there is the risk of burns due to high temperature.
•After every 50 hours of operation, detach the spark plug and remove dirt from the electrodes with a wire brush or similar.
•The correct electrode gap is 0.6 to 0.7mm.
