ADDITIONAL SAFETY RULES FOR GENERATORS

Do not force the generator. Use the correct generator for your application. The correct generator will do the job better and safer at the rate for which it was designed.
Do not use the generator if the engine switch does not turn it on and off. Any generator that cannot be controlled with the switch is dangerous and must be repaired.
Know exactly how to use the generator correctly. Be thoroughly familiar with proper use of the equipment and all engine controls, output receptacles, and connections. Know how to stop the engine quickly (see “Stopping the Generator”).
Instruct operators. The engine owner must instruct all operators in safe engine set-up and operation.
Only trained adults should set up and operate the engine – Do not let children operate.
Intended use. Carefully read about and understand the intended use of this engine. Do not use for other purposes, as unforeseen hazards or equipment damage may result.
Never operate, or let anyone else operate the generator while under the influence of alcohol, drugs, or medication.
Do not operate the generator with damaged, missing, or broken parts.
Do not modify the generator in any way. Modifications can create serious safety hazards and will also void the warranty.
Never attempt to modify the generator speed setting. The generator speed is preset for safe and optimal performance of the generator. If speed needs adjusting, it must be done by factory authorised personnel.
Never attempt to connect external fuel sources in order to increase generator run time. Larger tank at pressure or higher elevation will cause to leak from carburetor during operation. Fire or explosion could result.
Always turn off generator and remove spark plug(s) or spark plug wire(s) before working on the generator to prevent accidental starting. Always discharge the capacitor before working on the generator head to prevent electrical shock.  (See Maintenance & Repair section of this manual for instructions on how to do this.)
The running of a generator gives off carbon monoxide, a poisonous gas that can kill you. You CAN NOT smell it, see it, or taste it. Follow all instructions for site selection and positioning the generator, and avoid inhaling the exhaust. If  you start to feel sick, dizzy, or weak while using the generator, shut off the generator and get to fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.

WARNING
NEVER exceed the rated wattage capacity of your generator. OVERLOADING may cause SERIOUS DAMAGE to the generator and attached electrical devices and may result in fire.
Your generator MUST BE SIZED PROPERLY to provide both the running and starting (surge) wattage of the devices you will be powering. Before using your generator, determine the running and starting wattage requirements of all the electrical devices you will be powering simultaneously. Following below 4 simple steps and example on the right: Step 1. Determine the tools and appliances you want to power at the same time
Step 2. List the start up and running power usage (Watts) for each product
Step 3. Add the total power usage and add 10% as a safety net
Step 4. Choose a generator with a rated and maximum power that equals or exceeds your totals. In this case a generator with a rated power of at least 3108W and a maximum power output greater than 7233W would be required.

STARTING POWER CONSUMPTION
Electronic appliances and brushed motors generally will not draw more than running Watts at start up. Induction motors in equipment like air conditioners, welders, water pumps and compressors can draw 2 to 5 times their running  power to start. Please consult your equipment’s rating label, manual or the manufacturer to confirm specific requirement. If only the running wattage is given on the nameplate for a device with an electric motor, the starting wattage can  be approximated to be three to five times the running wattage. Estimates for the running wattage requirements for common devices are listed in the table below. Guidance for starting wattages is provided in the table’s footnotes. To size  your generator correctly you need to use Watts – here are some useful calculations: Watts = Volts x Amps Example 240 Volts x 5 Amps = 1200 Watts
