EUROPEAN HYDRAULIC TOOL MANUFACTURERS ASSOCIATION CODE OF PRACTICE – HYDRAULIC POWER SYSTEMS
Before Starting. Refer to manufacturer's operating instructions.
Compatibility.
Hydraulic Power Systems are designed to operate at a speci c Flow and Pressure. Equipment produced by EHTMA
members carries a triangular colour coded range identi cation label. Check that both the tool and power unit have
the same identi cation label before operation. It is imperative that power systems and tools having
different colour codings are not interconnected as this practice is both inef cient and dangerous.
For reference the EHTMA colour code is as follows:-

If in doubt consult the equipment manufacturer.
Characteristics. Operators not familiar with the use of hydraulic tools should note the following points:-
1) Hydraulic breakers are usually more powerful than the equivalent weight pneumatic tools.
2) The body of the hydraulic breaker and the supply hoses will become quite warm during normal operation.
3) As the breaker has no exhaust it is generally much quieter in operation. This should not be taken as a lack of power.
Safety Points.
1) Always wear safety footwear when operating breaking equipment.
2) Eye protection is strongly recommended, particularly on hard surfaces.
3) Ensure that the 'steel' is securely locked into the breaker.
4) Check hoses for deep cuts or exposed braiding; replace any damaged hose.
Safe Disposal.
Instructions for the protection of the environment. The
machine contains valuable materials. Take the discarded
apparatus and accessories to the relevant recycling
facilities.
