Introduction
Thank you for purchasing this McElroy product.
The McElroy® MegaMc® Pipe Stand allows efficient alignment
of pipe in the fusion machine jaws. Using the pipe stand's
34" vertical and 24" lateral adjustments, the pipe is efficiently
aligned with the fusion machine jaws. Aligning the pipe
quickly reduces the overall cycle time for the joint, increasing
productivity. Good alignment in the jaws means less stress
on the fusion machine, easier to close jaws and less hi-low
mismatch.
With reasonable care and maintenance, this machine will give
years of satisfactory service.
Before operating this machine, please read this manual
thoroughly, and keep a copy with the machine for future
reference. This manual is to be considered part of your machine.

Wear Safety Equipment
Wear a hard hat, safety shoes, safety glasses, and other applicable
personal protective equipment.
Remove jewelry and rings, do not wear loose-fitting clothing,
and tie back long hair that could catch on controls or moving
machinery.

Gas Powered Units
Gasoline engines will cause explosions when
operated in a hazardous environment. Do not
operate gas powered machines in a hazardous
environment.

Equipment Safety
FUEL
Fuel Handling
Gasoline and diesel fuel are extremely flammable
and their vapors will explode if ignited.
Do not fill the fuel tank while the engine is hot or running, as
spilled fuel could ignite.
Refuel in a well ventilated area. Do not smoke or allow flames or
sparks in the area where the engine is refueled, or where gasoline
is stored.
Do not start the engine near spilled fuel. Wipe up spills
immediately.
Make sure the fuel tank cap is closed and properly secured.
Avoid repeated or prolonged contact with skin or breathing of
vapor.
TX00953-2-19-97
CD00365c-3-31-97
Carbon Monoxide
Engine exhaust gases contain poisonous carbon
monoxide. Carbon monoxide can cause severe
nausea, fainting and death. Avoid inhaling
exhaust fumes, and never run the engine in a
closed or confined area.
TX00954-04-18-16
Crush Points
Hydraulically operated equipment operates
under high pressure and generates extremely
high forces. Anything inadvertently caught in
the machine will be crushed. Keep fingers, feet,
arms, legs, and head out of the machine while
operated. Always ensure machine power is off
before entering the machine for any reason.

Equipment Safety
Pipe Handling Safety
Do not position yourself under supported
or raised pipe or near the end of the pipe.
Pipe could travel uncontrolled on the rollers
in either direction and cause serious injury
or death.
In order to minimize the potential for the pipe to travel
uncontrolled, keep the pipe level when it is placed on the
rollers of the fusion machine and on the rollers of the pipe
stand(s). Hold pipe securely by either clamping in the fusion
machine jaws or by other means.
NOTICE: Do not leave stand unattended while HPU is
running. When not operating the pipe stand, turn off the
HPU to prevent accidental or unintentional movement of the
stand.
IMPORTANT: Engine does not need to be running to hold
load. However, do not leave raised pipe unattended as the
hydraulic pressure may bleed off over time and lower the
load.

Units With Hydraulics
It is important to remember that a sudden hydraulic oil leak
can cause serious injury, or even be fatal if the pressure or oil
temperature is high enough.
Escaping fluid under pressure can penetrate the
skin causing serious injury. Keep hands and
body away from pinholes which eject fluid under
pressure. Use a piece of cardboard or paper to
search for leaks. If any fluid is injected into the
skin, it must be immediately removed by a doctor
familiar with this type of injury.
Unwanted movement of the machine could result
in serious injury or damage to machine. Unwanted
movement of the machine may take place if switches
do not match machine state when the machine power
is turned on.
NOTICE: Wear safety glasses, and keep face clear of area when
bleeding air from hydraulic system to avoid spraying oil into eyes.
