−During use of the machinery and industrial use, people are subject to the risk of damage or
injury by mechanical elements in linear or gyrating movement, high voltage electric
components and static components under high temperature, due to which, during design
and construction of its equipment, ERM Engineering. has aimed to reduce and minimise
those risks by including protection devices and safety systems based on the European
Community Council Directives.
−Pay special attention to the following danger, prohibition and obligation signs located at
different places on the machinery:
-Installation and start-up:
Site the machine in working area and fix the two-back mast with metallic’s bolts on floor.
ATTENTION: DO NOT USE THE MACHINE IF NOT FIXED ON FLOOR; RISK OF
FALLING.
Install a vacuum cleaner and connect the milling head tube.
Connect power supply cable 3 phases 230V:

It must also be connected to a compressed air supply with input pressure 6 bar.
Place the tensioner body aligned with the driver roller to the size of 18 centimeters on the side
as shown on the picture.

NOTE: Depending on the strap length we can distance this tensioning body from the drive
head.
Connect the air tube of the tensioning body to the driving body.

-Operation:
Preparation
Remove the control knob from the support plate of the drive roller.
Remove the support from the drive roller to insert the “endless” belts for this, remove the
control knob.
Remove the support from the driver roller to insert the “endless” belts.
Insert the belt and then reassemble and fix the plate.

NOTE. Do not operate or tighten the belt without this fastening element, could cause mechanical
damage.
Then we will adjust the tension roller to the size of the tape, loosening the tension cylinder
moving it to the size required.
Place the tension roller inside the strap and tension the strap activating the valve of the tensor
cylinder.

Once the strap is tensioned adjust the roller guides.
To achieve a good centering of the strap, it is recommended to start-up the the drive motor to
the highest speed.
Now adjust the “milling” head and welding to the size required, to achieve this we must release
the brake from the welding head.
And from the milling head.

Fix both brakes once the elements are positioned.
Select the pulley to the size required and place it in the welding head.
Select the milling tool to the size required and assemble it, for this operation we will press the
two emergency stops.

WARNING: Remove the protective cover.
Remove the cover and using a 22mm key and 13mm key to break the shaft rotation.
NOTE: The nut screw of the milling tool is opposite of the usual way.
Start de Leister and program the weld temperature and air caudal.

When display stop to blink, minds that Leister is hot and ready to weld.
Adjust the belt speed, pressures of winder and unwinder and welder head pressures.
Note that any changes made to the temperature will not become effective until a few minutes
have elapsed. Adjusting the welding rate using the control potentiometer has immediate results.
Adjust the pressure by moving the pressure control knob located on the piston of the welding
pulley this adjustment only becomes effective on operating the pulley drive system, even though
it only affects the welding pulley.
NOTE: Check the weld by attempting to pull the welder joint.

-Care and maintenance:
➢Because various chemical components are used during the welding process, there is an
accumulation of highly corrosive waste in the welding area (rollers, pulleys, guides, etc.
and so they should be cleaned regularly to ensure correct operation.
➢Do not grease or lubricate any component of the machine.
These components are self-lubricated, and the mixture of different lubricants could cause
jamming or seizing.
➢Make sure the machine frame is always closed to prevent any deformation of the
structure.
➢Always make sure the black intake grille on the rear of the Leister is clean, if it is blocked
this would reduce the air flow rate and alter the weld quality.
➢Protect the pulleys from knocks that could mark or damage their profiles as they would
cause imperfections in the welding.
➢In the event of unusual noises in the welder, check the condition of the brushes. They
have relative wear.
