1. INTRODUCTION
This manual describes the use and maintenance
instructions of the KEZ pump, and should be carefully read
and understood before using the pump.
Correct use and adequate maintenance will guarantee the
pumps trouble-free operation for a long time. General
Pump declines any responsibility for damage caused by
misuse or the non-observance of the instructions indicated
in this manual.
Upon receiving the pump, check that it is complete and in
perfect condition.. Should anything be found out of order,
please contact us before installing and starting the pump.

3. SAFETY
3.1 General Safety Indications
The misuse of pumps and high pressure units may cause
severe injury to people and/or damage to property. Anyone
requested to assemble or use high pressure units must
possess the necessary competence to do so, should be
aware of the characteristics of the components assembled/used, and must adopt all the necessary precautions
in orter to guarantee maximum safety in any operating
condition. In the interest of safety, no precaution that is
reasonably feasible must be neglected, both by the
Manufacturer and the Operator.
3.2 High pressure unit safety requirements
1. The pressure line must always be equipped with a
safety valve.
2. High pressure unit components, in particular
for those units working outside, must be adequately
protected against rain, frost and heat.
3. The units electrical parts must be adequately
protected from water spray, and must comply with the
specific norms in force.
4. High pressure hoses must be correctly sized for the
units maximum operating pressure, and must only be
used within the pressure range indicated by the hose
manufacturer.
5. The extremeties of high pressure hoses must be
sheathed and fastened to a steady structure in order
to avoid dangerous whiplashes should they burst or
should their connections break.
6. Appropriate safety guards must be provided for the
pump transmission systems (joints, pulleys and belts,
auxiliary drives).

3.3 Safety During Operation
The working area of a high pressure system muste be
clearly signalled. Access must be prohibited to non-authorized personnel and, if possible, the area must be fenced
in. The personnel authorized to access this area must be
previously trained, and informed about the risks that may
arise from failures or malfunctions of the high pressure
unit.
Before starting the unit, the operator must check:
1. That the high pressure unit is correctly fed (see
paragraph 9.5).
Page 3
GENERAL PUMP
3.3 Safety of Operation (continued)
2. That pump intake filters are perfectly clean;
we advise to duse a device that indicates the filters
clogging level.
3. That electrical parts are adequately protected an in
perfect conditions.
4. That high pressure hoses do not show apparent signs
of abrasion, and that fittings are in perfect shape.
Any anamoly or reasonable doubt that may arise before or
during operation must be promptly reported and verified by
competent personnel. In these cases, pressure must be
immediately released and the high pressure unit stopped.
3.4 General Procedures For Using Nozzles
1. The Operator must always place his own and other
worker’s safety before any other interest; his actions
should always be governed by good sense and
responsibility.
2. The Operator must always wear a helmet with a
protective visor, waterproof clothing, and appropriate
boots capabl;e of guaranteeing grip on wet pavement.
Note: appropriate clothing will effectively protect against
water spray, but it may not offer adequate protecttion
against the direct impact of water jets or sprays from a
close distance. Some circumstances may require further
protection.
3. We advise to employ a team of at least two Operators,
able to provide mutual and immediate assistance if
needed, and to rotate their duties in case of long and
heavy work.
4. Access to the work area that is within the water jets’
range must be absolutely forbidden; the area must be
free of objects that may be unintentionally hit by the
pressurized jet, causing damage or dangerous situa
tions.
5. The water jet must only and always be directed towards
the work area, even during testing or preliminary
inspections.
6. The Operator must always pay attention to the trajecto
ry of the debris removed by the water jet. If necessary,
adequate side guards must be provided by the
Operator in order to protect anything that may be acci
entally exposed.
7. For no reason must the Operator be distracted during
operation. The personnel that needs to access the
working area must wait for the Operator to suspend his
work, and then immediately make his presence known.
8. For safety reasons, it is important that each member of
the team is perfectly aware of the intentions and actions
of other team members in order to avoid dangerous
misunderstandings,

9. The high pressure unit must not be started and
brought up to pressure unless each member of the
team is in his designated position, and the Operator
has already directed the nozzle towards the work area.
3.5 Safety During Unit Maintenance
1. The maintenance of the high pressure unit must be
done within the time intervals indicated by the
Manufacturer, who is responsible for the entire unit’s
compliance with the norms in force.
2. Maintenance must always be carried out by special
ized and authorized personnel.
3. Assembly and disassembly of the pump and its various
components must be performed exclusively by author
ized personnel, using appropriate tools in order to
avoid damage to components and connections.
4. To guarantee total reliability and safety, always use
original spare parts.
4. PUMP IDENTIFICATION
Each pump (fig. 1) has: its own serial number XX.XXX.XXX
(see point 1) and a rating plate (see point 2) that indicates:
Pump model and version
Maximum RPM
Power absorbed Hp-kW
Flow Rate l/mn - GPM
Pressure bar/PSI
Pump model, version and serial number
must always be specified when ordering
spare parts.
