1. ESSENTIAL SAFETY REQUIREMENTS
1.1 GENERAL CONSIDERATIONS.
LARZEP hydraulic electrical pumps have been specially designed and manufactured in accordance with our quality
standards and the controls demanded by the ISO 9001 standard. 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.
¾
In light of the above, it is important that the machine should only be used under perfect technical conditions and in accordance
with the considerations outlined in this manual. The operator should be aware of the risks inherent in the use of high-pressure
hydraulic appliances, familiar with the working of the machine and capable of giving the relevant orders to the personnel working
in the area.
¾
The machine is designed exclusively for the applications described in this manual. The manufacturer accepts no
responsibility for damage resulting from any other application or improper use.
1.2 ORGANISATIONAL PRINCIPLES
¾
The operator should have access to the instructions at all times.
¾
As a complementary precaution, in addition to the instructions manual, the operator should be instructed in the use of the
machine and the rules and regulations covering this type of operation, such as those relating to accident prevention and
environmental protection, for example.
¾
All personnel working with the machine must use personal protection equipment:
Boots, Helmets Goggles Gloves and Protective clothing.
¾
With the aim of avoiding personal injury or material damage, the operator should receive practical training in the use of the
machine, and be aware of and apply the necessary safety measures.
¾
Each time the machine is used; all personnel should follow the instructions outlined in the ‘Start up’ section of this instructions
manual.
¾
Never modify the equipment or add elements that affect its safety without the manufacturer’s express authorisation.
¾
Repairs and maintenance operations, etc. should only be carried out by specialist personnel. Always use original Larzep spare
parts.
¾
Replace the flexible hydraulic hoses on a regular basis, even if they show no signs of wear or damage.
¾
Maintenance operations should be carried out on a regular basis in accordance with the instructions outlined in this manual.
¾
Once you have finished using the machine, disconnect it, clean it and store it in a clean, safe place.
1.3 GENERAL SAFETY INSTRUCTIONS
¾
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.
¾
Before switching the machine on, make sure that no one is located in the danger zone.
¾
Check that the machine and its accessories have not been damaged during transportation and installation.
¾
Use the equipment in a well-light area.
¾
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.
You should calculate a maximum use of 80% of the machine’s nominal capacity.
Do not work under the load. If this is absolutely unavoidable, first block the load mechanically.
¾
Locate the load points in areas of maximum stability, and distribute the load uniformly.
Do not expose equipment to intense heat sources, such as welding, for example.
Eliminate pressure and disconnect the machine before carrying out maintenance operations.
¾
Never, under any circumstances, exceed the machine’s nominal capacity. Use indicators to monitor the operating pressure.
¾
Controls should be used with your hands. Do not use tools or levers, etc. for this purpose. When using tools (to regulate the
external limiting valve, for example), make sure you select the correct one and do not use excessive force.
¾
Clean the machine after use and store in a safe place where there is no risk of damage or dirt.
¾
Make sure that the plugs and accessories in general are kept perfectly clean. Dirty plugs are difficult to connect and may result in
dirt entering the hydraulic circuit.
¾
Make sure that the flexible hydraulic hoses are not twisted or flattened by loads.
¾
Make sure that the remote pendant is not activated and that the electro valve is in its standby or neutral position (centre open).
When using manual valves, ensure that they are set to position ‘C’ (centre) before initiating the operation.
¾
Never trust the load to the pump valves alone. Use safety valves when you wish to stabilise the cylinder pressure, and if
possible, block the load mechanically.
