Section 4 — Maintenance

Loosen the rocker jam nut. Use an 10mm allen wrench to turn the pivot ball stud while checking clearance between the rocker arm and the valve stem with a feeler gauge. Correct clearance is 0.002-0.004 inch (0.05-0.1 mm).

NOTE:

Hold the rocker arm jam nut in place as the pivot ball stud is turned.

When valve clearance is correct, hold the pivot ball stud in place with the allen wrench and tighten the rocker arm jam nut. Tighten the jam nut to 174 in.lbs. torque. After tightening the jam nut, recheck valve clearance to make sure it did not change.

Install new valve cover gasket.

Re-attach the valve cover. NOTE:

Start all four screws before tightening or it will not be possible to get all the screws in place. Make sure the valve cover gasket is in place.

Re-attach the spark plug wire to the spark plug.

Repeat the process for the other cylinder.

The maximum ambient temperature for the gen- erator is 40° C (104° F).

4.10 ATTENTION AFTER SUBMERSION

If the generator has been submerged in water, it MUST NOT be started and operated. Following any submersion in water, have an Authorized Dealer thor- oughly clean and dry the generator.

4.11 CORROSION PROTECTION

Periodically wash and wax the enclosure using auto- motive type products. Frequent washing is recom- mended in salt water/coastal areas. Spray engine linkages with a light oil such as WD-40®.

4.12 OUT OF SERVICE PROCEDURE

‹4.12.1 REMOVAL FROM SERVICE

If the generator cannot be exercised every seven days, and will be out of service longer than 90 days, pre- pare the generator for storage as follows:

4.9COOLING SYSTEM

Air 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, the engine/generator quickly overheats, which causes it to quickly shut down. (See Figure 4.7 for vent loca- tions.)

The exhaust from this product gets extremely hot and remains hot after shutdown. High grass, weeds, brush, leaves, etc. must remain clear of the exhaust. Such materials may ignite and burn from the heat of the exhaust system.

1.Start the engine and let it warm up.

2.Close the fuel shutoff valve in the fuel supply line and allow the unit to shut down.

3.Once the unit has shut down, it will signal a low oil fault.

4.Set the AUTO/OFF/MANUAL switch to OFF and turn off the utility power to the transfer switch. Remove the 7.5A and 15A fuses from the genera- tor control panel. Disconnect the battery cables as outlined in “General Hazards” (page 2).

5.While the engine is still warm from running, drain the oil completely. Refill the crankcase with oil. See ”Engine Oil Recommendations,” Section 4.3.1.

6.Attach a tag to the engine indicating the viscosity and classification of the oil in the crankcase.
