AIR FILTER

• The air filter, if clogged, will reduce the engine perfor-

mance. Check and clean the filter element in warm,

soapy water as required. Dry completely before in-

stalling. If the element is broken or shrunk, replace

with a new one.

FUEL FILTER

• When the engine runs short of fuel supply, check the

fuel cap and the fuel filter for blockage.

fouled spark plug. Clean the spark plug and check

that the plug gap is in the correct range. For a re-

placement plug, use the correct type specified by

KOMATSU ZENOAH.
