Do not use petroleum solvents such as kerosene
to clean the air cleaner. They may cause deterio-
ration of the air cleaner. DO NOT OIL THE AIR
CLEANER OR USE PRESSURIZED AIR TO CLEAN
OR DRY THE AIR CLEANER.
To service the pre-cleaner:
1. Wash in liquid detergent and water.
2. Squeeze dry in a clean cloth.
3. Saturate in clean engine oil.
4. Squeeze in a clean, absorbent cloth to remove all
excess oil.
CLEAN ENGINE: Remove dirt and debris with a cloth
or a brush. Do not clean with a forceful spray of
water. Water might contaminate the fuel system.
Periodically clean the muffler area to remove
combustible debris.
Clean Rotating Screen: If your POWER-ARC 4000 is
equipped with an engine that has a rotating screen,
you should clean it as often as needed, to remove dirt
or debris that may collect on the screen. A dirty
screen can result in engine overheating and damage.

vent. After cleaning or when installing a new spark
plug, set the terminal gap to .030 inch (.76 mm) with a
feeler gauge. See Figure D.4.
