8. oIL sensor
•
The oil sensor detects the fall in oil pressure in the crankcase and automatically stops the engine
when the oil pressure falls below a predetermined value.
•
When engine has stopped automatically, turn off the key switch of the generator, and check the oil
level. Refill engine oil to the upper level (see the part 5. pre-operation check) and restart the engine.
•
If the engine does not start by usual, consult your nearest Robin dealer or service shop.

Some appliances need a ‘‘surge’’ of energy when starting. This means that the amount of
electrical power needed to start the appliance may exceed the amount needed to maintain
its use. electrical appliances and tools normally come with a label indicating voltage,
cycles/Hz, amperage (amps) and electrical power needed to run the appliance or tool. Check with your
nearest dealer or service center with questions regarding power surge of certain appliances or power
tools.
•
electrical loads such as incandescent lamps and hot plates require the same wattage to start as is
needed to maintain use.
•
Loads such as fluorescent lamps require 1.2 to 2 times the indicated wattage during start-up.
•
Loads for mercury lamps require 2 to 3 times the indicated wattage during start-up.
•
electrical motors require a large starting current. Power requirements depend on the type of motor
and its use. Once enough ‘‘surge’’ is attained to start the motor, the appliance will require only 30%
to 50% of the wattage to continue running.
•
Most electrical tools require 1.2 to 3 times their wattage for running under load during use. For
example, a 5,000 watt generator can power a 1800 to 4000 watt electrical tool.
•
Loads such as submersible pumps and air compressors require a very large force to start. They need
3 to 5 times the normal running wattage in order to start. For example, a 5,000 watt generator would
only be able to drive a 1,000 to 1,700 watt pump.
note
The following wattage chart is general guide only. Refer to your specific appliance for correct wattage.
To determine the total wattage required to run a particular electrical appliance or tool, multiply the
voltage figure of the appliance/tool by the amperage (amps) figure of the same appliance / tool. The
voltage and amperage (amps) information can be found on a name plate which is normally attached to
electrical appliances and tools.
