Fusion Equipment Safety
General Safety
Safety is important. Report anything unusual that you notice
during set up or operation.
LISTEN for thumps, bumps, rattles, squeals, air leaks, or unusual
sounds.
SMELL odors like burning insulation, hot metal, burning rubber,
hot oil, or natural gas.
FEEL any changes in the way the equipment operates.
SEE problems with wiring and cables, hydraulic connections, or
other equipment.
REPORT anything you see, feel, smell, or hear that is different from
what you expect, or that you think may be unsafe.
TX00114-4-22-93

Wear Safety Equipment
Wear a hard hat, safety shoes, safety glasses, and other
applicable personal protective equipment.
Remove jewelry and rings, and do not wear loose-fitting clothing
or long hair that could catch on controls or moving machinery.
TX00032-4-7-93
Heater Is Not Explosion Proof
This heater is not explosion proof. Operation
of heater in a hazardous environment without
necessary safety precautions will result in
explosion and death.
If operating in a hazardous environment, the heater should be
brought up to temperature in a safe environment, then unplugged
before entering the hazardous atmosphere for fusion.

Electric Motors are Not Explosion Proof
Electric motors are not explosion proof.
Operation of these components in a hazardous
environment without necessary safety precautions
will result in explosion and death.
The armature brushes must be removed from the electric motor
when manually operating in a hazardous condition. Unscrew
the brushes from both sides of the motor. (Both brushes must
be removed). A 7/8" hex shaft allows for manual operation in
hazardous conditions.
TX00873-9-22-09
Electrical Safety
Always ensure power cords are properly
grounded. It is important to remember that you
are working in a wet environment with electrical
devices. Proper ground connections help to
minimize the chances of an electric shock.
Frequently inspect electrical cords and unit for damage. Have
damaged components replaced and service performed by a
qualified electrician.
Do not carry electrical devices by the cord.
NOTICE: Always connect units to the proper power source as
listed on the unit, or in the owner's manual. On units with two
power cords, plug each cord into separate power circuits. Do not
plug into both outlets of one duplex receptacle.
NOTICE: Disconnect the machine from the power source before
attempting any maintenance or adjustment.

Facer Blades Are Sharp
Facer blades are sharp and can cut. Never
attempt to remove shavings while the facer is
running, or is in the facing position between the jaws. Use care
when operating the facer, and when handling the unit.
NOTICE: Disconnect power from the facer, and remove the facer
blades before attempting any maintenance or adjustment.
NOTICE: Never extend the blade beyond the inner or outer
circumference of the facer.

Fusion Equipment Safety
Heater is Hot
The heater is hot and will burn clothing and skin.
Keep the heater in its insulated heater stand or
blanket when not in use, and use care when
heating the pipe.
NOTICE: Use only a clean non-synthetic cloth such as a cotton
cloth to clean the heater plates.
TX00104-8-12-94
Fusion Procedures
Obtain a copy of the pipe manufacturer's procedures or
appropriate joining standard for the pipe being fused. Follow the
procedure carefully, and adhere to all specified parameters.
Failure to follow pipe manufacturer's procedure
could result in a bad joint. Always follow pipe
manufacturer's procedures.

Do Not Tow Fusion Machine at Speeds Greater
than 5 MPH
The chassis is not designed for over-road towing.
Towing at speeds greater than five miles per
hour can result in machine damage as well as
injury. Always transport the machine by flatbed
truck or similar means, and make sure that unit is
properly secured.
TX00101-4-12-93
Periodically Check Temperature
NOTICE: Incorrect heating temperature can result in bad fusion
joints. Check heater plate surface temperature periodically with a
properly calibrated pyrometer, and make necessary adjustments.
The thermometer on heaters indicates internal temperature, and
should be used as a reference only.

Fusion Equipment Safety
Positioning Fusion Machine
Place fusion machine on as level ground as possible, and set the
brake on the rear wheel. If it is necessary to operate machine on
unlevel grade, chock the wheels and block the unit to make it as
stable as possible.
TX00112-9-15-94
Transporting 2LC and 2CU Units
On smaller machines it is easiest to carry the unit if the facer is
securely installed and locked on the fusion unit. The facer has a
handle that allows the unit to be firmly grasped and carried.
NOTICE: Do not carry unit by the lever handles because they
can release or bend. Care must be used if the unit is grasped
elsewhere because numerous pinch points exist.
