Introduction and
technical
specifications
Foreword
MEP S.p.A.,in response to modern production techniques, has developed the new
SHARK 282.
This work tool has been designed to satisfy the wide range of cutting needs of a
modern workshop with simplicity and reliability, while at the same time
complying with all EEC safety standards.
The SHARK 282 is structurally rigid, silent and safe: it produces a minimum of
waste (1.2 mm) while its great versatility makes it suitable for cutting various
materials such as stainless steel light alloys, aluminium, copper and bronze at
high speed and with high precision.
Its high cutting capacity, combined with the possibility of making inclined cuts
from 60° left to 45° right, make this model the ideal solution for satisfying the
wide strange of cutting needs of machine shops, turneries, structural steel shops
and engineering workshops.
We congratulate our clients on having chosen this product, which will give
effective and faithful service for many years, especially if the instructions
contained in this use and maintenance manual are carefully followed.
This cutting machine has been designed and made specifically for cutting
metallic materials.

1--2 2 Use and maintenance manual SHARK 282
Machine presentation
Functioning is completely manual: the operator, after having checked the
workpiece in the vice, grips the control lever and presses the bandsaw start
microswitch; with a downwards movement, the material is cut to the preset
length; the cutting head returns up at the end of the cutting operation, ready to
start a new work cycle.
In the MA version (Automatic Vice), a pneumatic cylinder applied on the vice
blocks the material between the jaws: the open/close control is located on the
base of the machine.
With the CCS accessory (Cut Control System), the machine can also perform a
semi---automatic work cycle. The operator, after using the selector located on the
control panel to choose the semi---automatic work cycle, clamps the material in
the vice and presses the button on the cutting head handgrip to start up the
bandsaw; the saw begins turning and the head commences its downstroke, the
speed of which can be adjusted using the control valve (head downstroke speed
regulator) located on the control panel. The head performs the cutting operation;
once the cut has been made, a limiter stops the cutting cycle, after which the head
is manually returned to its upper position so that, when a new workpiece is in
place, a new cycle can be started using once more the handgrip button.
Both the Automatic Vice and the Cut Control System are optional for the
SHARK 282 model; they can be factory installed on request made during the
ordering procedure, or may be installed by the user after the machine has
been bought.

Cutting head
The cutting head is the unit that cuts the material. It consists of a cast iron head
on which the following are mounted: the band saw, the blade guide components,
the blade tensioner components, the transmission box and the spindle motor. The
cutting head is limited in its movements by the joint on the work table, and its
cutting stroke is manually guided by the operator.

Control Panel
The control panel has a protection rating of IP 54 and contains the electrical
equipment. Access is gained by removing the screws fastening a safety panel,
while the operator’s safety is guaranteed by a key---operated safety switch,
designed to prevent any intentional interference with the unit. In order to remove
the panel from its mounting, the main switch has to be shifted to 0 (OFF), which
automatically cuts off the electrical supply.

Safety and accident
prevention
The SHARK 282 has been designed and produced in accordance with European
standards. For the correct use of the machine we recommend that the
instructions contained in this chapter are carefully followed.
Use of the machine
The SHARK 282 band saw cutting machine is intended exclusively for cutting
metallic materials, ferrous or non---ferrous, in section or solid.
Other types of material and machining are not compatible with the specific
characteristics of the saw.
The employer is responsible for instructing the personnel who, in turn, are
obliged to inform the operator of any accident risks, safety devices, noise
emission and accident prevention regulations provided for by international
standards and national laws regarding the use of the machine. The operator must
be perfectly aware of the position and function of all the machine’s controls.The
instructions, warnings and accident prevention standards in this manual must be
respected without question by all those concerned.The following definitions are
those provided for by EEC MACHINES DIRECTIVE 2006/42/CE :
H“Danger zone”: any zone in and/or around a machine in which the presence of a
person constitutes a risk for the safety and health of that person.
H“Person exposed”: any person finding himself either completely or partly in a
danger zone.
H“Operator”: the person or persons given the responsibility of installing, operating,
adjusting, maintaining, cleaning, repairing or transporting the machine.
The manufacturer declines any responsibility whatsoever, either civil or
criminal, should there be unauthorised interference or replacement of one or
more parts or assemblies on the machine, or if accessories, tools and
consumable materials are used that are different from those recommended by
the manufacturer itself or if the machine is employed in a plant system and its
proper function is thereby altered.

General recommendations
LIGHTING
Insufficient lighting for the types of operation envisaged could constitute a safety
hazard for the persons concerned. For this reason, the machine user must provide
lighting in the working area sufficient to eliminate all shadowy areas while also
avoiding any blinding light concentrations. (Reference standard ISO 8995---89
“Lighting in work environments”).
CONNECTIONS
Check that the power supply cables and pneumatic feed systems comply with the
maximum machine absorption values listed in the “Machine Specification” tables;
replace if necessary.
EARTHING
The installation of the earthing system must comply with the requirements set out
in IEC STANDARD 204.
OPERATOR POSITION
The position of the operator controlling machine operations must be as shown in
the diagram below.
