• Make sure the piston is at Top Dead Center (TDC)of its compression stroke (both valves closed). Toget the piston at TDC, remove the intake screen atthe front of the engine to gain access to the flywheelnut. Use a large socket and socket wrench to rotatethe nut and hence the engine. While watching thepiston through the spark plug hole. The pistonshould move up and down. The piston is at TDCwhen it is up as high as it can go.• Loosen the rocker jam nut. Use an 10mm allenwrench to turn the pivot ball stud while checkingclearance between the rocker arm and the valvestem with a feeler gauge. Correct clearance is0.002-0.004 inch (0.05-0.1 mm). See Figure 4.6.NOTE:Hold the rocker arm jam nut in place as the pivotball stud is turned.When valve clearance is correct, hold the pivot ballstud in place with the allen wrench and tighten therocker arm jam nut. Tighten the jam nut to 174in/lbs. torque. After tightening the jam nut, recheckvalve clearance to make sure it did not change.Figure 4.6 - Valve Clearance AdjustmentJam NutPivot BallStudRockerArmValveStem• Install new valve cover gasket.• Re-attach the valve cover.NOTE:Start all four screws before tightening or it will notbe possible to get them in place. Make sure thevalve cover gasket is in place.• Re-attach the spark plug wire to the spark plug.• Repeat the process for the other cylinder.4.9 COOLING SYSTEMAir inlet and outlet openings in the generator com-partment must be open and unobstructed for con-tinued proper operation. This includes such obstruc-tions as high grass, weeds, brush, leaves and snow.Without sufficient cooling and ventilating air flow, theengine/generator quickly overheats, which causes itto quickly shut down. (See Figure 4.7 for vent loca-tions.) The exhaust from this product gets extremelyhot and remains hot after shutdown. High grass,weeds, brush, leaves, etc. must remain clear ofthe exhaust. Such materials may ignite and burnfrom the heat of the exhaust system.Figure 4.7 – Cooling Vent Locations The maximum ambient temperature for thegenerator is 48.9° C (104° F).4.10 ATTENTION AFTER SUBMERSIONIf the generator has been submerged in water, it MUSTNOT be started and operated. Following any submer-sion in water, have a dealer thoroughly clean and drythe generator.4.11 CORROSION PROTECTIONPeriodically wash and wax the enclosure using auto-motive type products. Frequent washing is recom-mended in salt water/coastal areas. Spray enginelinkages with a light oil such as WD-40.Section 4 — Maintenance15 kW Generator19
