5.CLEANING FUEL CUP (See Fig. 7-r)

WARNING Flame Prohibited

(1)Inspect fuel cup for water and dirt. (See Fig.7-r-q)

(2)To remove water and dirt, close the fuel valve and remove the fuel cup.

(3)After removing dirt and water, wash the fuel cup with kerosene or gasoline. Reinstall securely to prevent leakage.

6.CLEANING AIR CLEANER (See Fig.7-t,y)

A dirty air cleaner element will cause starting difficulty, power loss, engine malfunctions, and shorten engine life extremely. Always keep the air cleaner element clean.

WARNING Flame Prohibited

(1)Urethane Foam Element Type (See Fig.7-t)

Remove the element and wash it in washing oil (kerosene). Then saturate it in engine oil and squeeze it firmly before installing. (See Fig.7-t-q)

(2)Urethane Foam Dual Element Type (See Fig.7-y)

■For EX13/16/17 urethane foam, remove it from the paper element and wash it in washing oil (kerosene). Then saturate it in engine oil and squeeze it firmly before installing. (See Fig.7-y-w)

■ For EX27/40 urethane foam, remove it from the paper element and wash it thoroughly with detergent. Then dry it before installing. (See Fig.7-y-w)

■ For the paper element, clean by blowing on it with

■Pull the casing toward you, and then remove the casing and the inner casing.

■Clean the inside of pump casing and casing cover with clean water.

10.HIGH ALTITUDE ENGINE OPERATION

■Please have an authorized SUBARU Industrial Power Products dealer modify this engine if it is to be run continuously above 5000 feet (1500 meters). Failure to do so, may result in poor engine performance, spark plug fouling, hard starting, and increased emissions.

■Carburetor modification by an authorized SUBARU Industrial Power Products dealer will improve performance and allow that this engine meets EPA (Environmental Protection Agency) and California ARB (Air Resources Board) emission standards throughout its useful life.

■An engine converted for high altitudes can not be run at 5000 feet or lower. In doing so, the engine will overheat and cause serious engine damage.

Please have an authorized SUBARU Industrial Power Products dealer restore high altitude modified engines to the original factory specification before operating below 5000 feet.
