USER MANUAL
(TERMS OF WARRANTY)
Introduction
User manual of the 2200x0.8 (3050x0.8) folding machine is the basic equipment of the
machine. To meet the requirements of construction companies and sheet metal working
plants we started to manufacture a new model of a manual folding machine with high
reliability, outstanding durability and aesthetic appearance.
Before using this machine, please read this manual carefully. Please follow the instructions
and safety rules when operating this machine. If you find the information included in this
manual unclear please contact your retailer or the manufacturer for assistance.
. Intended use
This folding machine is intended to fold steel sheets in straight lines up to the max. angle of
45° ( 35° for 3-meter folding machine) and max. thickness of 0.8 mm for steels sheets.
2. Safety rules
This folding machine can only be operated by an adult person who has read this manual and
is familiar with the rules for safe work and operation.
When working on the machine observe the basic safety regulations for steel sheet handling,
use personal protective equipment and use the machine as intended. Where the machine is
operated by two persons do not tamper with the movable parts of the machine if you are not
sure that the hands of your partner are outside the working areas of the machine.
The machine should be placed on a stable and even surface with the minimum distance from
a wall or the nearest partition being less than 50 cm to ensure easy and safe operation of the
machine. No bystanders should be in the vicinity of the machine. Keep order by placing the
finished products at a safe distance from the machine.
Do not allow the folding machine to be operated by unexperienced persons. Protect the
working area to prevent the access of children and animals.
Pay special attention to your fingers as they can be injured by the pressing beam or the
folding beam. To ensure safety the upper beam should always be in extreme positions i.e.
closed or open. To minimize the risk of the pressing beam dropping the machine is equipped
with two gas springs (not applicable to 2.5- and 3-meter folding machines except for
customized machines).
When moving the folding beam, the pressing beam should always be closed.
Any defects or damages found during the operated can be repaired by an authorized person
only or the manufacturer in case of more complicated defects.
The folding machine must not touch food directly and it should not be used in a potentially
explosive atmosphere.

4. Design
The 2200x0.8 folding machine is composed of:
- main frame, fixed part with a square cross section,
- upper pressing beam, a moving part with a triangular cross section,
- folding beam, moving part with a rectangular cross section,
- base, two screwed T-shaped feet,
- optionally, the machine can be equipped with a circular knife or a coiler.
5. Operation of the folding machine
The machine is delivered disassembled. Upon acceptance of the folding machine the user should
check the completeness of the delivery and perform a visual inspection to find any damage
caused in transit. Before starting the operation install the feet by fastening them with 0x 6 mm
bolts and put the machine in an upright position.
The machine is ready to operate when delivered to the user.
The operator must use the folding machine according to the safety requirements.
To keep the machine in an operational condition it must be maintained and the folding edges,
welded and bolted joints inspected need to be inspected.
The maintenance includes all the machine cleaning operations, general corrosion preventive
maintenance and operation checks. Frequency of maintenance inspections: once per quarter.
Perform lubrication every 00 hours of operation. Use ŁT-43 grease or machine oil.
6. Description and principle of operation
Sheet folding operation can be performed only after circular knifes are installed, if included in
the machine equipment.

Lift the sheet pressing lever with a rotary movement until resistance is felt, the pressing beam is
in the upper position. Insert the sheet part to be folded and set the position. Clamp the upper
beam by pressing the lever until resistance is felt and the eccentric mechanism, the machine is
equipped with, is engaged.
Hold the beam and lift it. Use the pre-installed protractor to adjust the required sheet folding
angle. Loosen the pressing beam and take out the part.
The folding machine is adjusted by setting the folding components so that the sheet being folded
is even. The manufacturer guarantees the tolerance of mm in the length of 2.000 mm.
Remember that stress is produced in the sheet when being cut and the stress is released when the
sheet is folded for the first time to produce slight curvature of the edge being folded. The
phenomenon is corrected with the second folding to stiffen the whole part.
Eccentric clamp can be adjusted with M20 nuts marked A and B, respectively. With the folding
machine closed loosen nuts B on both sides and tighten nuts A while observing the pressure gap
in the back of the machine. The gap should be visible but must not be larger than 0.5 on both
sides. Adjust the position of the central part of the clamp with the M 2 nut marked E.
When adjusting the folding arm needs to be raised to the horizontal position and the gaps on the
left and on the right must be inspected visually (they should be identical). Loosen nuts C and D
to fine tune the machine and retighten them to lock the settings. the central part of the folding
beam should be tight according to the thickness of the sheet metal to be worked, by using the
M 2 nut inside the profile (you will need a ring spanner 9 mm). All the components are
illustrated in detail No. . The required tightness should be locked with the M 2 nuts visible
from the outside.

7. Transport and storage
Both short- and long-distance transport can be performed only after the folding arm is fixed to
protect it from rotating, by using a tie-down strap or any other effective method. In the case of
longer distances the folding machine should be transported on a platform of any means of
transportation. The machine should be fixed, preferably with tie-down straps, and protected
from mechanical damage for transportation.
Store the folding machine in conditions which ensure protection from corrosion and prevent any
damage.

9. Adjustment of circular knives
The circular knives the OLMET folding machine is equipped with are factory-set and ready to
use.
If the knives need to be adjusted e.g., due to incorrect use or the frame fork being bent please
follow the instructions below:
a) Place the knives on a guide on the top of the clamping beam – Fig. 1 – A

b) The adjustment is carried out by loosening and tightening the
M 2 nuts on the fork Fig. 1 – B
c) The frame should be tilted towards the guiding (clamping)
beam up to the max. 5° - Fig. 1
d) Adjustment of circular knives against each other: knife edges should overlap by approx. ~ .5
mm, and are driven by each other due to the friction against the flank face – Fig.1 – C.
They are adjusted after prior loosening of the nuts on the spindles of the circular knives.
e) Knife cutting line is approx. 3~4 mm above the sheet metal line after it is fixed in the folding
machine. Use the longitudinal openings of the knife frame to adjust the cutting line height –
Fig. 1 – D
f) Foot (heel) of the knives should be set below the level of the sheet metal to be cut – Fig. 2 - E
Fig.

g) It is advised to move the rear part of the knife frame away from the front part a couple of
degrees – Fig. 2
