TRANSPORTING AND LIFTING
IMPORTANT: Lifting and carrying operations should be carried out by skilled workers,
such as a truck operator, crane operator, etc. If a crane is used to lift the machine, attach the
lifting chain carefully, making sure the machine is well balanced.
Follow these guidelines when lifting with truck or trolley:
•The lift truck must be able to lift at least 1.5 – 2 times
the machines gross weight.
•Make sure the machine is balanced. While
transporting, avoid rough or jerky motion, and maintain
a safe clearance zone around the transport area.
•Use a fork lift with sufficient lifting capacity and forks
that are long enough to reach the complete width of
the machine.
•Remove the securing bolts that attach the machine to
the pallet.
•Approaching the machine from the side, lift the machine on the frame taking care that there
are no cables or pipes in the area of the forks.
•Move the machine to the required position and lower gently to the floor.
•Level the machine so that all the supporting feet are taking the weight of the machine and no
rocking is taking place.
Follow these guidelines when lifting crane or hoist:
•Always lift and carry the machine with the lifting holes provided at the top of the machine.
•Use lift equipment such as straps, chains, capable of lifting 1.5 to 2 times the weight of the
machine.
•Take proper precautions for handling and lifting.
•Check if the load is properly balanced by lifting it an inch or two.
•Lift the machine, avoiding sudden accelerations or quick changes of direction.
•Locate the machine where it is to be installed, and lower slowly until it touches the floor.

INSTALLATION
IMPORTANT:
Consider the following when looking for a suitable location to place the machine:
•Overall weight of the machine.
•Weight of material being processed.
•Sizes of material to be processed through the machine.
•Space needed for auxiliary stands, work tables, or other machinery.
•Clearance from walls and other obstacles.
•Maintain an adequate working area around the machine for safety.
•Have the work area well illuminated with proper lighting.
•Keep the floor free of oil and make sure it is not slippery.
•Remove scrap and waste materials regularly, and make sure the work area is free from
obstructing objects.
•If long lengths of material are to be fed into the machine, make sure that they will not extend
into any aisles.
•LEVELING: The machine should be sited on a level, concrete floor. Provisions for securing it
should be in position prior to placing the machine. The accuracy of any machine depends on
the precise placement of it to the mounting surface.
•FLOOR: This tool distributes a large amount of weight over a small area. Make certain that
the floor is capable of supporting the weight of the machine, work stock, and the operator.
The floor should also be a level surface. If the unit wobbles or rocks once in place, be sure to
eliminate by using shims.
•WORKING CLEARANCES: Take into consideration the size of the material to be
processed. Make sure that you allow enough space for you to operate the machine freely.
•POWER SUPPLY PLACEMENT: The power supply should be located close enough to the
machine so that the power cord is not in an area where it would cause a tripping hazard. Be
sure to observe all electrical codes if installing new circuits and/or outlets.

ELECTRICAL
Motor Specifications
Your tool iswired for 240 volt, 50Hz alternating current. Before connecting the tool to the
power source, make sure the machine is cut off from power source.
Considerations
•Observe local electrical codes when connecting the machine.
•The circuit should be protected with a time delay fuse or circuit breaker with a amperage
rating slightly higher than the full load current of machine.
•A separate electrical circuit should be used for your tools. Before connecting the motor to the
power line, make sure the switch is in the “OFF” position and be sure that the electric current
is of the same characteristics as indicated on the tool.
•All line connections should make good contact. Running on low voltage will damage the
motor.
•In the event of a malfunction or breakdown, grounding provides a path of least resistance for
electric current to reduce the risk of electric shock. This tool is equipped with an electric cord
having an equipment-grounding conductor and a grounding plug. The plug must be plugged
into a matching outlet that is properly installed and grounded in accordance with all local
codes and ordinances.
ATTENTION: HAVE ELECTRICAL UTILITIES CONNECTED TO MACHINE BY A
CERTIFIED ELECTRICIAN!
Your Baileigh Machine is Certified
Check if the available power supply is the same as required by the machine (consult
nameplate on machine)
WARNING: Make sure the grounding wire (green) is properly connected
to avoid electric shock. DO NOT switch the position of the green grounding wire if any
electrical plug wires are switched during hookup.
WARNING: In all cases, make certain the receptacle in question is
properly grounded. If you are not sure, have a qualified electrician check the
receptacle.

•Improper connection of the equipment-grounding conductor can result in risk of electric
shock. The conductor with insulation having an outer surface that is green with or without
yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric
cord or plug is necessary, do not connect the equipment-grounding conductor to a live
terminal.
•Check with a qualified electrician or service personnel if the grounding instructions are not
completely understood, or if in doubt as to whether the tool is properly grounded.
•Repair or replace damaged or worn cord immediately.

WIRE GAUGE
An undersized cord decreases line voltage, causing loss of power and overheating. All cords
should use a ground wire and plug pin. Replace any damaged cords immediately.
Power cord connection:
1. Turn the main disconnect switch on the control panel to the OFF position.
2. Unwrap the power cord and route the cord away from the machine toward the power supply.
a. Route the power cord so that it will NOT become entangled in the machine in any
way.
b. Route the cord to the power supply is a way that does NOT create a trip hazard.
3. Connect the power cord to the power supply and check that the power cord has not been
damaged during installation.
4. When the hammer and dies area is clear of any obstruction. The main disconnect may be
turn ON to test the operation. Turn the main disconnect to OFF when the machine is not in
operation.

OPERATION
The MH-19 Reciprocating Hammer is a multi-stroke reciprocating machine, capable of many
different metal forming operations. In the next few steps, we will explain each mode of operation
as well as setting the tooling
Power Hammer Mode
In power hammer mode, the upper slide ram is connected to the crank toggle mechanism via a
multi stack leaf spring. As the crank turns, speed and momentum load the spring which in turn
“throws” the upper slide ram down with spring force and gravity. The amount of throw and force
are controlled by speed and/or stroke.
The speed is controlled through a
variable foot control and a limiting
potentiometer on the upper control box.
The foot control fully depressed will max
out at whatever the limiting potentiometer
is set to.
1. To set the machine to power hammer
mode the control box must be turned
in the “off” position.
2. Remove the shear bolt (A) and
bushings in the upper rear lever
connection point. Store the bolt and
spacer bushings in a safe place.
Removing the bolt will separate the
leaf spring from rigid mode and the
spring will be free to move.
3. Next, the stroke can be set. Insert the
hand wheel (B) onto the hex shaft.
CAUTION: Always wear proper hearing and
eye protection with side
shields, safety footwear, and leather gloves to protect from burrs and sharp edges.
Keep hands and fingers clear of the hammer dies.
When handling large heavy sheets make sure they are properly supported.
WARNING:
HEARING PROTECTION MUST BE WORN AT ALL TIMES
WHEN OPERATING THIS MACHINE.

4. Rotate until the scale (C) reads .400, this
is a good place to start for thumbnail
shrink dies. Tighten the lock lever.
5. To install the tools, remove the 1” quick
release pin (D) and drop the lower tool
holder out of the way, then remove the
1/2" pins (E).
6. Install the tools and re install the pins.
7. After the tools are installed, the gap needs
to be set. To set the gap, turn the main
crank hand wheel (F) to the “bottom dead
center” or the lowest the slide ram will go.
8. Loosen the down feed lock lever (G) and
rotate the down feed hand wheel (H) until the
gap between the tools is about 1/4". This is
where most dies work the best. Make sure all
lock levers are tight and the quick release pins
are fully installed. Check the motion, tool
clearance and verify the gap by rotating the
main crank hand wheel (F).
9. Set the control switch (I) to the “ON Foot
Control” position.
10.Set the limiting potentiometer (J) to about 1000
BPM (Beats Per Minute), slowly press the foot
control, the machine should begin to
“hammer”, hitting harder the faster you go.
WARNING: The tools on this machine should never come in contact with
each other, if they do, machine damage will occur.

11.Shrinking as well as most of the shaping functions will take time to learn and control. To
practice shrinking, use 3003-H14 .059 wall aluminum. This is a good material to learn on
because it shapes easily and is more forgiving. To shrink start feeding the metal in slowly
controlling the shrink by your foot control; slowing as you pull out not to flatten the edge too
much.
12.The hammer mode is also used for planishing. Install the flat top die and the 6000R x 1000F
lower hammer die. This die has a contact patch of 1” diameter. Install the tools following the
same steps as before. Adjusting the stroke will give different results. Shortening the stroke
will allow different speed settings, faster speeds can be achieved by finding the “sweet spot”,
just before the spring begins to float. The stroke CAN be adjusted on the fly. The
combinations of stroke / speed / down feed are almost endless.
13.These dies can be used for planishing as well as stretching. The flat top die is used for most
of the stretching applications except for aggressive doming. The rubber die can be installed
on either the top or bottom depending on your application.
Rigid Mode
Rigid mode is used for functions similar to a Pullmax® machine. The hammer spring is
deactivated and bolted rigid. This mode is used for short stroke tooling such as beading,
flanging, mechanical shrinking, mechanical stretching etc.
1. To set the machine in this mode, turn the control switch to “Off”.
2. Loosen the down feed lock lever and rotate the down feed hand wheel to lift the upper
tooling all the way “up”. This will allow enough clearance to install the lock bolt.
3. Install the lock bolt and bushings through the lever assembly and tighten to 50ft.lbs. The lock
bolt is designed to shear off if the machine is set to crash, or the load is too great.
4. With the bolt in place, install the mechanical stretch dies. There is no top or bottom, but
make sure they are both “stretch” dies.
IMPORTANT: With the tools installed, it is very important that the tool gap is set
properly or the shear bolt will fail.
5. Always set your tools with the main crank hand wheel. The gap should be set to material
thickness first, then slowly bring the slide ram down to get the desired stretch. Be careful not
to give it too much stretch or the tools may bottom out. The stroke should be no greater than
.250 and the max speed around 200 BPM. Use the foot control to work the stretching tools.
6. Beading tools can be installed in the same fashion; but the tool clearance is more critical. It
must be slightly greater than the material thickness.
7. When beading or flanging, use of the roller fence will ensure perfectly straight forms. Setting
the roller fence is self-explanatory.

15
15
8. When beading, flanging, or forming the control can be either foot or the preset “on”,
whichever the user wants.
9. The maximum speed is 1500 BPM; you should only use maximum BPM if the stroke is set to
the minimum. Most forming applications in rigid mode work at 1000 BPM.
10.Another common tool in this mode is a joggle tool which can be simply made from 1/2" mild
steel and installed in the universal tool holder.
English Wheel Mode
Note: Optional tooling required.
1. To set the machine to English wheel mode, the main power switch must be turned off to
prevent accidental machine start up.
2. The machine must be in rigid mode.
3. Set the stroke to the minimum and bottom dead center.
4. Remove all the tooling and quick release pins.
5. Now you can install the upper wheel assembly. The down feed may need to be adjusted
down to gain enough clearance for the wheel assembly. It is best if two people do this job,
one person holding the wheel assembly, and one person to install the 1/2" quick release pin.
6. Once the pin is installed, the pinch bolt can be tightened locking the upper wheel assembly
onto the slide ram.
7. Raise up the upper wheel with the down feed hand wheel and install the lower wheel holder
onto the lower tool holder receiving hole, install the 1/2" quick release pin.
8. Choose a lower roller and drop it into the saddles and lower the upper wheel to match the
material thickness. The lower wheel can be tipped by loosening the center arc bolt and
rotating its holder, this is used for “tipping” or edging panels.
9. When wheeling, the down force is controlled by the down feed hand wheel.
