1PRESENTATION AND GENERAL ASPECTS
1.1 GENERAL POINTS
The SENA key cutting machine has been designed on the basis of the safety standards
currently in force in the EU.
The safety of the personnel involved in the handling of this type of machines can only be
achieved with a well designed worker safety programme, like the implementation of a
maintenance programme and following recommended advice as well as compliance with
the safety standards included in this manual.
Although the machine is not difficult to install, it is best not to try to install, adjust or use it
without having first read this manual.
The machine leaves our factory ready for use and only requires calibration operations for
the tools that are going to be used.
1.2 TRANSPORT AND PACKING
The machine comes inside packing with the following dimensions:
Width = 520 mm, length = 600 mm, height = 500mm
Weight of machine plus packing = 55 Kg.
When you unpack the machine, check carefully if it has suffered any damage during
transportation. If you find any problems, please inform the carrier immediately and do not
do anything with the machine until the carrier’s agent has carried out an inspection.
1.3 IDENTIFICATION LABEL
The SENA key cutting machine has an identification label, specifying the serial number,
manufacturer’s name and address, the CE mark and the year of manufacture.

2CHARACTERISTICS OF THE MACHINE
The SENA key cutting machine is a professional semi-automatic key cutting machine.
It has been prepared to cut single and double bladed bit keys, pump keys, Muel type keys and
vertical groove keys. The machine’s design enables all the models of key mentioned to be cut
without having to change the slide, only having to move the slide to the correct position. These
characteristics make it a versatile machine.
The clamps have been designed to ensure that the keys are clamped correctly. Flat keys and
wedge bit mortice keys can be cut.
The clamp-holder slide is mounted on guides that slide on roller cages. This system provides the
machine with maximum precision, rigidity and sensitivity when it is being used.
Asynchronous motor with two speeds which provides greater flexibility when cutting keys
(speed1: steel, speed2: brass).
It also has an adjustable lamp to light any area of the machine and a brush for removing burrs on
the key.

2.5 PRELIMINARY OPERATIONS AND WARNINGS.
Place the machine on a solid table that will withstand the weight, bearing in mind that the line
and machine voltage must be the same.
The machine has been tested at our facilities before being sent out.
Before starting up the machine and carrying out any operation, block the X and Y slides with
controls 16 and 17.
The key clamping operations and slide movements must be carried out with the machine switched
off.
Positions on the clamp-holder slide:
Sliding the slide on the dovetail, position one of the three reference points Rwith the base
reference point S.
•The first reference point R1 is for cutting single and double bladed bit keys.
•The second reference point R2 is for cutting pump keys and Muel type keys.
•The third reference point R3 is for cutting keys with vertical grooves, wedge bit mortice
and ADPLE1,2,3,4 keys.
Once the slide is in the correct position, block it by turning the knobs (15).
