Section 1 — General Information

Guardian Liquid-cooled 10 kW, 15 kW, 20 kW and 25 kW Generators

INSPECTION:

After unpacking, carefully inspect the generator for any damage that may have occurred during shipment. If loss or damage is noted at the time of delivery, have the person(s) making delivery note all damage on the freight bill or affix his signature under the consignor’s memo of loss or damage.

LIFTING THE GENERATOR

WARNING: When lifting or hoisting equipment is used, be careful not to touch overhead power lines. The gener-

ators weight of more than 900 pounds requires proper tools, equipment, and qualified personnel to be used in all phases of handling and unpacking.

ENGINE OIL RECOMMENDATIONS

The unit has been filled with 15W-40 engine oil at the factory. Use a high-quality detergent oil classified “For Service CC, SD, SE, SF.” Detergent oils keep the engine cleaner and reduce carbon deposits. Use oil having the following SAE viscosity rating, based on the ambient temperature range anticipated before the next oil change:

Temperature	Oil Grade (Recommended)
Above 80° F (27° C)	SAE 30W or 15W-40
32° to 80° F (-1° to 27° C)	SAE 20W-20 or 15W-40
Below 32° F (0° C)	SAE 10W or 15W-40

CAUTION: Any attempt to crank or start the engine before it has been properly serviced with the recommended oil may result in an engine failure.
