DUAL ELEMENT AIR CLEANER SERVICE
Refer to the Maintenance Schedule at the end of this sec-
tion and ensure that the recommendations are followed.
More frequent service is required when operating in ad-
verse conditions.
- Gain access to the pre-cleaner (4) and cartridge (5)
by loosening screw (2) and cover (3).
- To service the pre-cleaner, carefully remove and
wash in a solution of liquid detergent and water. Al-
low to air dry thoroughly before replacing.
- Clean the cartridge by tapping gently on a flat sur-
face. If very dirty, replace or wash in a solution of
non-foaming detergnt and warm water. Rinse thor-
oughly with running water from the mesh side until
the water is clear. Allow the cartridge to stand and
air dry thoroughly before replacing. Do not use pe-
troleum solvents during cleaning as this will cause
the cartridge to deteriorate. Do not use pressurised
air as this may damage the cartridge. Do not oil the
cartridge.
- After servicing, install the pre-cleaner and car-
tridge in the cover. Insert the tabs on the bottom of
the cover into the slots in the bottom of the base (6).
Tilt the cover upwards and securely tighten the
screw to the base.

SPARK PLUG SERVICE

spark as shown in the diagram.
Replace the spark plug every 100 hours or every season,
whichever occurs first. A spark plug wrench is available
from any authorised Briggs & Stratton service dealer.
The spark plug gap (2) should be checked with a feeler
gauge and set at 0.76mm (0.030").
