Frame Ground Connection
WARNING: Be sure the system is properly grounded before applying power. Do not apply AC power
before you ensure that grounds are connected. Electrical shock can cause serious or fatal
injury. NEC requires that the frame and exposed conductive surfaces (metal parts) be
connected to an approved earth ground. Local codes may also require proper grounding of
generator systems.
The NEC requires that the frame and exposed metal surfaces be at local ground reference
potential to avoid electrical shock hazard. A local ground reference may require a driven earth
ground conductor at the generator installation site. Make the ground connection as shown in
Figure 3-3. Use the appropriate size wire (normally 6 AWG) as required by NEC and local
codes. The local reference ground is normally a copper clad earth ground rod driven into the
earth at least 8 feet or as necessary to reach the water table.

Engine Oil Refer to the engine manual that was provided with your generator. Determine the correct type of
engine oil and the amount specified by the engine manufacturer. Add the required amount of oil
to bring the oil level to full.

Use of Electric Motor Loads
Electric motors require much more current (amperes) to start them than to keep them running.
Some motors, particularly split−phase motors are very difficult to start and require 5 to 7 times
more current to start them. Repulsion−induction type motors are the easiest to start and normally
only require 2 to 3 times as much current to start them.
Most fractional horsepower motors take about the same amount of current to start them and
keep them running. This is true whether they are the repulsion−induction type motor, capacitor
type motor, or the split−phase type motor.
Other factors that influence the amount of current needed to start a motor are:
1. The type of load connected to the motor. If the electric motor is connected to a hard
starting load such as an air compressor it will require more starting current. If the same
electric motor is connected to a light load such as a heater or power saw it will require
less starting current.
2. The brand or design of the electric motor. The expected starting current for a
particular size motor will vary depending on the brand of the electric motor as well as
the type of electric motor (Split Phase, capacitor, Repulsion−induction type, etc.)
3. The condition of the electric motor. A clean motor with free turning bearings will
require less starting currents than a similar type motor that is dirty and the bearings are
not as free turning as they used to be.
Optional Wheel Kit
PDG2 − 2 Wheel Dolly Kit; and PDG4 − 4 Wheel Dolly Kit
An optional 2 or 4 wheel dolly kit is available for portable generators. If you have purchased one
of these kits, refer to MN2409 for the installation instructions.
