1. SAFETY ESSENTIAL REQUIREMENTS
GENERAL CONSIDERATIONS
The LARZEP hydraulic electric pumps have been designed in accordance with our Quality Standards and under the control described by the ISO
9001 rules. Nevertheless, improper use may result in the death or serious injury of the user and third parties, as well as causing grave damage to
the machine and related materials.
The machine is exclusively designed for the operations described in this manual. No other uses are foreseen and therefore the manufacturer will
not feel responsible for any damages caused by a wrong operation of the tool.
ORGANIZATIVE PRINCIPLES
The instructions guide must be always available at user’s reach.
Hydraulic equipment can be used with such little effort that it is often easy to forget the magnitudes of force involved. As a complement to the
instruction manual, the user should be trained as far as the machine operation and the corresponding safety and technical rules are concerned,
such as those about prevention of accidents and protection of environment.
The operators must wear protective clothes like helmet, goggles,
gloves, boots, protective clothing and others.


In order to prevent any personal or material damage, the operator should be duly trained in the working operation and apply the relevant
safety actions.

Whenever the machine is used, the steps described in the paragraph “START UP” of this manual should be followed.

Any modification on the equipment or replacement of components affecting the general safety should be avoided without the previous
authorisation by the manufacturer.

Any repairing and maintaining operation, etc. should be done only by specialised staff and with original LARZEP spare parts.

Replace the hydraulic hoses periodically, even if they show no signs of wear or damage.

Maintenance operations should be carried out on a regular basis in accordance with the instructions outlined in this manual.

After operation, the machine should be disconnected, cleaned and stored in a safe and clean place.
GENERAL SAFETY INSTRUCTIONS
Before starting the operation, make sure that the user will work steady. Operate the equipment in a well‐light area.

Before switching the machine on, make sure that no one is located in the danger zone.

All the material in the installation should be securely installed and thoroughly stable, and the operator fully aware of all the movements to
be carried out during the application.

If you notice that the machine or one of the installation’s elements is not working properly, stop the operation in process immediately,
block the load and then correct the problem.

Locate the load points in areas of maximum stability and distribute the load uniformly.
Bearing the above in mind, obviously the use of the pump must be done as per the relevant instructions described in the manual.
The operator must be aware of the inherent risks when handling high pressure hydraulic devices, command properly the working
operation and instruct accordingly the staff staying nearby to the working area.
Check that both the machine and the accessories have not been damaged during transportation, handling or installation.
Ensure that all the components of the hydraulic system can support the maximum pressure.
You should calculate a maximum use of 80% of the machine’s nominal capacity.
Never, under any circumstances, exceed the nominal capacity of the machine. Use indicators to monitor the operating pressure.
Do not work under the load. If this is absolutely unavoidable, first block the load mechanically.
Do not expose the tool to intense heat sourcing, such as welding.
Eliminate pressure and disconnect the machine before carrying out maintenance operations.
