PREFACE Thank you for purchasing a Hyundai Portable generator. Please register your product in order for us to ensure your continuous satisfaction with our product. This manual covers the safety, operation and maintenance proce- dures for the HHD3500, HHD6250 and HHD7250 models.
1. SAFETY PRECAUTIONS 1.1) Safety Labels DANGER This symbol warns of hazards which can result in severe or lethal personal injury. WARNING This symbol refers to a hazardous or unsafe practice which has the potential to result in personal injury or product / property damage.
• Gasoline is a highly flammable and explosive liquid. Refuel in a well ventilated area with the engine stopped. • When refueling the generator, keep it away from cigarette, open flames, smoke and/or sparks. • Connections for standby power to a building’s electrical system must be done by a qualified electrician and must comply with all applicable laws and electrical codes.
damages to the generator set. 1.4) Maintenance Safety • After any maintenance is performed, wash your body immedi- ately using soap and clean water because repeated exposure to lubricant may cause skin irritation. • Do not clean the filter element with flammable liquids like gasoline because explosion may occur.
3. PRE-OPERATION INSPECTION WARNING Exhaust gas contains poisonous carbon monoxide. Never run the generator in an enclosed area. Be sure to provide adequate ventilation Operate the generator on a level surface. If the generator is tilted, fuel spillage may result Keep away from rotating parts while the generator is running.

Valve Lever Fig. 4.9 If the engine is cold, pull the choke lever out to close the choke. Refer to Fig. 4.10 Choke Open Close Fig. 4.10 Turn the engine switch to the ON position, and hold it until started, but the start time cannot be more than 5 seconds, otherwise the alternator might be damaged.
Do not use the choke if the engine is warm or if the air temperature is high (above 50 4.3) Using the Generator Set For HHD3500 Turn off the switches of the device before connecting to the generator Select the receptacles to be used by using the AC Voltage Selector.
Page 33
Fig. 4.12 If the 120V/240V option of the selector switch is chosen, insert the plug of the device into the 120V/240V receptacle. Refer to Fig. 4.13 Fig. 4.13 Turn the Master Breaker to ON and turn on the device. Refer to Fig.

Visually inspect the spark plug. Discard it if the insula- tor is cracked or chipped. Clean the spark plug with a brush if it is to be reused. Measure the plug gap with a feeler gauge. The gap should be 0.7 to 0.8 mm (0.028 to 0.031 inch). Correct as necessary by carefully bending the side electrode.
