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.
(See Figure D.2).

blast the spark plug clean with an abrasive cleaning
device. Clean the plug by scraping it or by using a
wire brush. Wash the plug with a commercial sol-
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.
