SAVE THESE INSTRUCTIONS TABLE OF CONTENTS This manual contains important instructions that should be followed during installation and maintenance of the generator and batteries. Read and understand all instructions in the manual before starting and operating the generator set. USING THIS MANUAL Congratulations on your choice of a Winco generator set. You have selected a high-quality, precision-engineered generator set designed and tested to give you years of satisfactory standby service.
IMPORTANT SAFETY INSTRUCTIONS 2. a. b. SAVE THESE INSTRUCTIONS This manual contains important instructions that should be followed during installation and maintenance of the generator and batteries. This engine generator set has been designed and manufactured to allow safe, reliable performance. Poor maintenance, improper or careless use can result in potential deadly hazards; from electrical shock, exhaust gas asphyxiation, or fire.
TESTING POLICY: Before any generator is shipped from the factory, it is fully checked for performance. The generator is loaded to its full capacity, and the voltage, current, and frequency are carefully checked. Rated output of generators is based on engineering tests of typical units, and is subject to, and limited by, the temperature, altitude, fuel, and other conditions specified by the manufacturer of the applicable engines.

INSTALLING THE FUEL LINE **** CAUTION **** EQUIPMENT DAMAGE - These units must be mounted on a solid concrete pad to prevent air from exiting under the unit. Allowing air to exit under the unit may cause the unit to overheat from lack of proper air flow. Before beginning the installation process recheck the rating of the generator set and its transfer switch rating. Be certain they can handle the intended load and are compatible with the entrance voltage, phase and current ratings.

The supply line is connected to a liquid withdrawal valve on the supply tank and runs directly to the fuellock strainer mounted on the engine generator set.
CAUTION – PERSONAL DANGER CAUTION - NEVER dispose of a battery in a fire. The battery is capable of exploding. CAUTION - DO NOT open or mutilate the battery. Released electrolyte is known to be harmful to the skin and eyes and to be very toxic. These engine generator sets are all NEGATIVE ground. Be very careful not to connect the battery in reverse polarity, as this may short circuit the battery charging system on the engine.
