The DAYLIFF Range of portable petrol generators are dependable, quality products specially designed for mains standby and remote site power supply applications. Particular features of all DG-P models are:

• Reliable and economical air cooled OHV petrol engines equipped with large size exhausts and air cleaners for low noise operation.
• High efficiency square core alternators providing consistent AC power output.
• DC output option for powering DC appliances (Not DG3000E)
• Option of strong tubular frame, trolley mount (T-suffix), canopied (S-suffix) and Economy (E-suffix) low-cost models suited for lighter applications.
• Integrated control panel with selection of different controls for operational convenience
• Fuseless type over current protection.
• Oil alert system to stop engine in the event of low oil level(not DG950P, DG1200P).
• High capacity fuel tank for extended operation (not DG950P).

Also available is the high specification DG4000PSi model that includes inverter technology with the following features:-

• High specification petrol engine incorporating automatic speed control that adjusts engine speed to load leading to reduced operation fuel consumption, reduced emissions and quieter operation.
• Square core alternator fitted with a digital inverter that gives regulated 50Hz frequency and perfect sine wave output suitable for all types of sensitive electronic equipment

Dayliff DG generators are of compact design and their advanced features, reliability and economy of operation make them the ideal solution for all small scale power supply requirements

GENERAL DATA

2. SAFETY WARNINGS

	Read and carefully understand the Instruction Manual before use.
	Avoid proximity to fire when refueling highly inflammable!
	Ensure good ventilation around the generator and do not operate indoors. Exhaust gases are very poisonous
	Do not use generator on a slope. Fuel spillage may occur and cause a fire.
	Do not restrict the exhaust silencer. There is a danger of overheating and fire.
	Do not connect generators together. Generator damage will occur.
	Ensure a competent trained person is used in case of overhaul.

3. CONTROLS

All generators are fitted with the following:-

• 2no. 3 pin AC outlets, +ve and -ve DC connections. DG950 with one outlet.
• Engine on/off switch.
• Magnetic circuit breaker electric cutout.
• Voltmeter (not DG950)

4. ELECTRICAL CONNECTIONS

If the generator is to be connected for standby power use ensure a qualified electrician is employed. The generator must be isolated from the utility power when connected or serious damage will result to the generator and house power circuits.

• Ensure total load does not exceed the generator rating. Maximum power output must only be used briefly or generator damage will occur.
• Ensure total load does not exceed the generator rating. Maximum power output must only be used briefly or generator damage will occur.
• DC output to be used for charging automotive and solar 12V batteries only. Ensure correct polarity when connecting cables, i.e +ve to +ve and -ve to -ve generator to battery terminals.
• Ensure the generator is properly earthed. Consult a qualified electrician if in doubt.

5. GENERATOR OPERATION

Always start generator before applying load by switching the circuit breaker and stop the generator after disconnecting load. Starting and stopping under load will damage the generator and powered accessories.

• CHECK ENGINE OIL. Operating without oil will cause severe engine damage and invalidate the warranty.
• To start ensure ignition ‘ON’, fuel valve ‘ON’ and choke ‘ON’. Then either pull starter cord (manual start) or turn key (electric start). For electric start do not turn the engine on for more than 5 seconds. If ti fails to start release the switch and wait 15 seconds before re-trying. Switch off choke when engine has started.
• Check output voltage is 240V on the voltmeter. If not adjust engine speed. If the speed setting is correct and the voltage is low then the generator is overloaded and load must be reduced.
• If more than an appliance is connected apply load progressively with greatest load first.
• Close fuel valve whenever generator is not operating.
• DG950 generators use two-stroke engines and oil must be pre-mixed with petrol at the ratio of 50:1. Use fuel tank cap as an oil measure adding one inverted capfull for each litre of fuel. Engine damage will occur without pre-mixed oil.

6. ROUTINE MAINTENANCE

For Diesel engines see separate engine manual. The below instructions apply to petrol versions only.

ENGINE OIL

• Check engine oil daily. If low refill with SAE30.
• Change engine oil after first month or after 20hrs operation and thereafter every 3 months or 50 hours of operation, in both cases whichever is sooner.

AIR CLEANER

Check the air cleaner every 3 months or after 50 hours operations, whichever is the sooner. Clean by blowing away accumulated dust and soaking in kerosene.

SPARK PLUG

A correctly set spark plug in good condition is essential for efficient engine operation. Check the plug every 3 months or after 50 hours operation, clean with a wire brush and set the electrode gap to 0.7-0.8mm. If general conduction is unsatisfactory it should be changed with a NGK (BPR5ES) or similar.
