Wanco Two-Bearing Belt-Drive Generators

Operation

3.1

Before starting

3.1.1

Safety

Before operating the Wanco Generator:

Read and be familiar with this instruction manual.

Read and follow all safety instructions (see Section 2, page 5).

If using an engine to power the generator, read the engine 
manufacturer’s instructions.

3.1.2

Power requirements

You must supply the power source—usually an engine—for use 
with your generator. The factory does not supply engines.

All engines have a horsepower curve. Always operate the engine at 
a speed that develops the required horsepower, as listed in 
Table 3-1.

If you do not have enough horsepower from the engine, you will 
not obtain the full electrical output from the generator. If you 
attempt to draw full power from the generator without enough 
horsepower, the result will be low voltage and higher amperage, 
which will damage the generator and the equipment you are 
powering with the generator.

The generator will not operate properly if powered by a tractor (as a 
PTO generator). The RPMs from a tractor engine are too low. If a PTO 
generator is required, contact the factory.

CAUTION

Insufficient horsepower will damage generator and other 
connected equipment.

Use a power source that is properly sized for the generator.
