Pre-Start Checks; Ehtma Code Of Practice - Belle Group 188-00010 Manuel De L'opérateur

The following components must be checked before you can use the saw safely. Running the saw with an undetected defect in either
of these components will quickly cause equipment damage.
Hydraulic System
1. Before making any hydraulic connections, inspect all hoses for leaks and risks of rupture as follows:
Inspect each hose for breaks, cracks, worn spots, bulges, chemical attack, kinks or any other damage. Never stop any detected
leak with your hand or fi ngers. Do not put your face close to suspected leaks. Hold a piece of cardboard close to suspected leaks
and then inspect the cardboard for signs of hydraulic oil. Replace a damaged hose immediately. Never repair the hose.
2. Connect the return (tank) line from the saw return port to the hydraulic power source return port. Then connect the pressure line
from the saw pressure port to the hydraulic power source pressure port. Clean fi ttings before making connections to
prevent contamination of hydraulic system.
3. Pressure relief valve must not exceed 2500 psi @ 8 gpm. The pressure relief valve must be located in the supply circuit between
the power supply and tool to limit excessive hydraulic pressure to the tool.
Flanges and Blade
1. Inspect the fl ange and arbor fl ange for gouges, hairline cracks, and wear. Replace these fl anges immediately if any of these
conditions are present as described in the Service and Maintenance section.
2. Be sure fl anges are clean and straight so blade will run true on sides.
3. Always use the blade recommended by the blade manufacturer for your application. Use approved dry cutting type blades in dry
cutting operations and approved wet cutting type blades in wet cutting operations.
4. Inspect the blade for cracks, chips, gouges, or loose or missing tips. Destroy the blade if any of these conditions are present.
5. Insure a blade is installed to blade manufacturer's specifi ed direction of rotation. Saw rotation is clockwise as viewed from the
blade side of the saw.
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 specifi c Flow and Pressure. Equipment produced by EHTMA
members carries a triangular colour coded range identifi cation label. Check that both the tool and power unit have
the same identifi cation label before operation. It is imperative that power systems and tools having
different colour codings are not interconnected as this practice is both ineffi cient and dangerous.
For reference the EHTMA colour code is as follows:-
Classifi cation Colour Code.
A Yellow
B Blue
C Green
D Brown
E Red
F Black
G Orange
Z Grey
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.
