Turning the crankshaft by han during adjusting or cleaning might start the engine, and cause serious injury to th operator.   ■ Operate the engine on a stable, level surface.   If the engine is tilted, fuel spillage may result.   NOTE   Operating the engine at a steep incline may cause seizure due to improper lubrication   even with a maximum oil level.   ■ Do not transport the engine with fuel in tank or with fuel strainer cock open.   ■ ■ Do not move the engine while in operation when it has been removed from the   equipment.   US   Keep the unit dry (do not operate it in rainy conditions).   WARNING   : WHEN CHARGING THE BATTERY   ■ ■ Battery electrolyte contains sulphuric acid. Protect your eyes, skin and clothing. In   case of contact, flush thoroughly with water and get prompt medical attention,   especially if your eyes are affected.   Batteries generate hydrogen gas, which can be highly explosive. Do not smoke or   allow flames or sparks near a battery, especially during charging.   ■ ■ Charge the battery in a fully ventilated location.   Be sure to confirm Battery polarity.   CAUTION   : PRE-OPERATION CHECKS   ■ ■ Carefully check fuel hoses and joints for looseness and fuel leakage. Leaked fuel   creates a potentially dangerous situation.   Check bolts and nuts for looseness. A loose bolt or nut may cause serious engine   trouble.   ■ ■ ■ ■ Check the engine oil and refill if necessary.   Check the fuel level and refill if necessary. Take care not to overfill the tank.   Keep cylinder fins and recoil starter free of dirt, grass and other debris.   Wear snug fitting working clothes when operating the engine.   Loose aprons, towels, belt, etc., may be caught in the engine or drive train, causing a   dangerous situation.   3 Download from Www.Somanuals.com.

INSPECTING THE SPARK PLUG   (See Fig.7 w)   6. CLEANING AIR CLEANER   (See Fig.7 y,u)   - - (1) Clean off carbon deposits on the spark plug electrode   using a plug cleaner or wire brush.   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.   (2) Check electrode gap. The gap should be 0.6 mm to 0.7   mm (0.02 inch.-0.03 inch.). Adjust the gap, if necessary,   WARNING Flame Prohibited   by carefully bending the side electrode.   Recommended Spark Plug : NGK BR-6HS   (CHAMPION RL86C)   (1) Urethane Foam Element Type   (See Fig.7 y)   - ■ Remove the element and wash it in kerosene or diesel   fuel. Then saturate it in a mixture of 3 parts kerosene or   diesel fuel and 1 part engine oil. Squeeze the element   to remove the mixture and install it in the air cleaner.   4. ENGINE OIL CHANGE (See Fig. 7-e,r)   Initial oil change   Thereafter   : After 20 hours of operation   : Every 100 hours of operation   (2) Urethane Foam Dual Element Type   (See Fig.7 u)   US   (1) When changing oil, stop the engine and loosen the drain   plug.

After   cleaning, dry it. Clean the urethane foam element every   50 hours.   CAUTION   To prevent injury, pay attention to the hot oil.   ■ Second element (See Fig.7   -u   -q)   Clean by tapping gently to remove dirt and blow off dust.   Never use oil. Clean the paper element every 50 hours   of operation, and replace element set every 200 hours.   (2) Re-install the drain plug before refilling oil.   OIL CAPACITY : EX13/17/21: 0.6 liter   EX27: 1.1 liter   Clean and replace air cleaner elements more often when   operating in dusty environments.   (3) Refer to page 5 for the recommended oil.   ■ Always use the best grade and clean oil.

FUEL HOSE REPLACEMENT (See Fig.7-i)   oil, poor quality oil and shortage of oil cause damage to   engine or shorten the engine life.   WARNING   Take extreme caution when replacing fuel   hose ; gasoline is extremely flammable.   5. CLEANING FUEL CUP   (See Fig. 7-t)   Replace the fuel hose every 1,000 hours or every year.   If fuel leaks from fuel hose, replace the fuel hose immediately.   WARNING Flame Prohibited   (1) Inspect fuel cup for water and dirt.   (See Fig.7-t   -q)   8. CHECKING BOLTS, NUTS AND SCREWS   ■ Retighten loose bolts and nuts.   (2) To remove water and dirt, close the fuel cock and remove   the fuel cup.   ■ Check for fuel and oil leaks.   (3) After removing dirt and water, wash the fuel cup with   kerosene or gasoline. Reinstall securely to prevent   leakage.   ■ Replace damaged parts with new ones.   9.
