Important safety precautions
This manual contains critical safety information. Please read the entire manual closely.
Because safety is paramount and using a generator carries significant responsibilities, we have outlined
warnings and the general hazards of operating generators. In addition, we have summarized the
recommended procedures for operating, repairing, maintaining, and storing your specific generator to
keep you and others safe.
It would be impossible for us to warn you of each risk and all of the hazards involved in the use of
generators. Therefore, it’s essential that you use your best judgment and take precautions when using,
maintaining, repairing, and storing your generator.
There are many safety warnings in this manual and on the generator itself to guide you:
Generator safety labels: The safety labels on your generator warn of potential danger. It’s
critical that you read them. If any labels become difficult to read or have been removed, contact
your dealer for a replacement label.
Manual safety messages: This manual contains specific instructions and severe warnings
about the ramifications of using poor judgment and not following the instructions outlined in this
manual. The ramifications range from serious injury and losing consciousness to death.
Manual headings and sections: We’ve devoted several sections of this manual to outline the
risks, hazards, and warnings when using, repairing, maintaining, and storing your generator.
Pay attention to cautions such as, “Carbon monoxide WARNINGS” or “Electric shock WARNINGS” or
“Burn and fire WARNINGS.”
Not following instructions or using poor judgment when using
and maintaining your generator can cause you or someone
else to be
KILLED
or
SERIOUSLY INJURED.

Safety warnings
Carbon Monoxide WARNINGS
Only operate your generator outdoors.
Operating a generator carries serious responsibility. There are precautions that you need to take when
operating a generator:
•Never operate your generator indoors
or near any windows or doors.
•Never operate your generator in an
enclosed or a partially enclosed area
such as a garage.
•Do not let the exhaust from your
generator build up to dangerous
levels.
•Do not breathe the poisonous gas in
your generator’s exhaust.
•Become familiar with your generator.
Understand all of your generator’s
controls, connections, and output receptacles. Know how to quickly stop your generator in case of
an emergency.
•If anyone else operates your generator, be sure he/she is properly instructed.
•Do not let children play with or operate your generator.
•Keep your generator at least seven feet away from flammable materials.
The exhaust from your generator contains carbon monoxide.
Breathing this poisonous gas, which is odorless and colorless, can
cause unconsciousness and could even kill you.

DG66M-R62, -B62 & DG67M-R62, -B62
Electrical shock WARNINGS
•Keep your generator dry.
•Do not operate your generator when your hands are wet.
•Do not operate your generator in wet conditions such as rain, snow or fog. Do not use it near a pool
or sprinkler.
•Store your generator in a dry place. If your generator is stored outdoors and is not protected from the
weather, check the electrical components on the Control Panel before each use. Look for moisture
and ice, which could cause your generator’s electrical components to malfunction or short circuit.
This could result in electric shock or electrocution.
•Do not exceed your generator’s wattage or amperage capacity. Exceeding these limits could damage
your generator and any device attached to it.
•If you use your generator on highly conductive areas such as metal decking or steel work, use a
ground fault circuit interrupter.
•Do not use electrical cords that are damaged, worn, bare or frayed.
•Do not touch your generator’s bare receptacles or wires.
•Always properly ground your generator. Failing to ground your generator could result in electric
shock or electrocution.
Your generator is equipped with a system that connects its frame components to the ground
terminals in the AC output receptacles.
This system and the AC neutral wire are not connected.
Therefore, if you test your generator with a receptacle tester, it will not produce the same ground
circuit condition as would be the case for a home receptacle.
Your generator produces significant electrical power.
It could cause electric shock or even electrocution if not used properly.
System Ground Terminal Location

DG66M-R62, -B62 & DG67M-R62, -B62
Electrical system WARNINGS
When connecting to a building’s electrical system for standby power, this
connection must be made by a qualified electrician. This connection must
isolate your generator’s power from the utility’s power and remain in
compliance with all electrical codes and applicable laws.
•Do not connect your generator to a commercial power outlet such as a building’s electrical
system unless an isolation switch is used, and that switch was installed by a qualified electrician.
•Improperly connecting your generator to a building’s electrical system could allow electrical
current from your generator to backfeed into the utility’s lines. This could electrocute utility
employees and others who make contact with the lines during a power outage. Your generator
could also explode, burn, or cause fires when the power is restored. Consult a qualified
electrician and/or the utility company before proceeding.
Burn and fire WARNINGS
•Stop engine when refueling.
•Do not smoke when refueling your generator.
•Keep your generator at least seven feet (or 2 meters) away from buildings and equipment.
•Keep flammable materials away from your generator.
•Do not allow sparks or flames near your generator when it’s refueled and keep them away
from your stored gasoline.
•Fuel vapors are highly flammable, so they could ignite after your generator is started. Wipe
up any spilled fuel before you restart your generator.
•Do not operate your generator in enclosed or partially enclosed areas.
•Avoid touching your generator’s muffler. It becomes extremely hot when your generator is in
use. It remains hot for quite a while after you turn your generator off, so wait to move your
generator into storage until the muffler has completely cooled to avoid severe burns.
Your generator’s exhaust system becomes hot enough that it
could ignite some materials and cause severe burns.
Gasoline is highly flammable and can be explosive, so use
extreme caution when refueling and operating your generator.

2. First, you’ll place the wheels on the frame.
To do this, place the washer on the axle and insert it from the inside of the
frame toward the outside of the frame as shown at right;
Then, install the spacer as shown;
Place wheel onto axle;
Secure wheel with nut and then repeat the steps above on the other
wheel: *Use M16 x 1.5 nuts
3. Next, attach the front support. On the handle side of the
generator, lift and support the bottom of the frame to enable the
assembly of the front support: *Use M8 x 16 bolts and M8 nuts.
Then, fasten the foot bar onto the generator by
threading the bolts into the holes in the frame of the
generator at the points shown. Tighten the bolts.
4. The last step is attaching the handle.

18 | Page
DG66M-R62, -B62 & DG67M-R62, -B62
Please note there are two different length bolts; the longer bolt will go through the upper hole and
the short bolt through the lower hole:
Start by installing the upper bolt and nut to hold the handle in place, only tighten by hand at this
point.We will tighten the bolt later: * Use M8 x 35 bolts and M8 nuts.
Now partially remove the handle pivot bolt as shown to allow the
insertion of the lower bolt. This bolt is an M8 x 50.
Next secure the upper and lower bolts by tightening them with the
wrenches or sockets as shown.
Now reassemble the handle pivot bolt and tight enough
that the handle moves freely and will drop down from its’
own weight. Then repeat these steps for the other handle.
When complete the handles should look like the photo.
Handle Operation:
These handles have a self locking mechanism that must
be set before raising the handle. Simply raise the locking
pin up and away from the frame into this position. Then
raise the handle, the handle should lock with the locking
pin moving forward and dropping into the locking slot. To
lower the handles just pull up on the locking pins and the
handles will drop.
