General Safety
The following precautions should be taken before operating Belle Hydraulic
Power Units and Road Breaking Tools.
a) Read this Operators Guide and the operating handbook for the tool to be
connected and run. Observe the manufacturers recommendations.
b) Never operate the power units and tools without the correct Personal
Protection Equipment. Belle recommend the use of protective goggles and/or
face shield, ear defenders, protective footwear, gloves, and hand hat.
c) Ensure that the ‘STEEL’ is securely locked into the breaker.
d) Only operate the Power unit in a well Ventilated area ensuring adequate flow
of air for the cooling fan and the removal of the exhaust gases.
e) Ensure that a safe operating work position (Workstation) is selected. Belle
recommend that tools are operated at the extremity of the transmission
hoses connecting the tool to the power unit.
f) Ensure that the hydraulic tool is compatible with the hydraulic power supply
to be used. It is DANGEROUS to use a hydraulic tool with an incompatible
flow rate and pressure.
NOTE:- Hydraulic power units and tools supplied by EHTMA member companies
carry range identification labels and it is
essential to check that the tools and power unit have the same identification label.
g)
h)
j)
Check the power unit, hoses and tools frequently for damage and/or leaks.
Do not adjust the power pack settings, ie:- the engine speed/flow rate, Relief
Valve pressure setting etc. Operating with flows and pressures outside the
specifications can be dangerous.
Use only Belle replacement parts. It can Prove dangerous to fit obscure
parts.

EHTMA - Code Of Practice

CODE OF PRACTICE – HYDRAULIC BREAKERS
Before Starting. Refer to manufacturer’s operating instructions.
Compatibility.
Hydraulic tools are designed to operate at a specific Flow and
Pressure. Equipment produced by EHTMA members carries a
triangular colour coded range identification label. Check that both the
tool and power unit have the same identification label before
operation. It is imperative that power systems and tools having
different colour codings are not interconnected as this practice is both
inefficient and dangerous.
For reference the EHTMA colour code is as follows:-

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.
Steel Selection It is essential that the correct type and size of steel is chosen if
optimum performance is to be achieved, with particular reference
being made to the shank length and across flat dimensions.
Recommendations as follows:Material.
Recommended Steel
Concrete.
Pointed or narrow bladed chisels.
Tarmac.
Sharp edged wide bladed tools with straight cutting edges.

Health & Safety
Vibration
Some vibration from the machines operation is transmitted through the handle to the
operator’s hands. The Belle Group Hydraulic Breaker range has been specifically
designed to reduce hand/arm vibration levels. Refer to specifications & technical data for
vibration levels and usage times (recommended maximum daily exposure time). DO NOT
exceed the maximum usage times.
PPE (Personal Protective Equipment)
Personal injury or property damage may be caused by knocks, crushing, slipping, tripping,
falling, or by flying chips due mainly to the improper or careless handling of the machine,
or working in a confined area.
Suitable PPE must be worn when using this equipment i.e. Safety Goggles, Gloves, Ear
Defenders, Dust Mask and Steel Toe capped footwear.
Wear clothing suitable for the work you are doing. Tie back long hair and remove any
jewellery which may catch in the equipment’s moving parts.
Dust
Using the Hydraulic Breaker can produce dust, which may be hazardous to your health.
Always wear a mask that is suited to the type of dust being produced..
Pre-Start Checks
ENSURE THAT ALL HOSE COUPLINGS ARE THOROUGHLY CLEANED
BEFORE CONNECTING. FAILURE TO DO SO MAY CAUSE DAMAGE TO
CAUTION THE SEALS.
2) Check that connection has been made to a suitable Power Unit delivering 201/min
EHTMA Category ‘C’ and 140 Bar Max. Presure. It is DANGEROUS to use the
hydraulic breaker with an incompatible flow rate and pressure.
3) Make sure that the unit will not start when the hydraulic power is applied by checking
that the trigger is free and not stuck in the down position.
4) Ensure that the ‘Steel’ is securely locked in the breaker and the latch is properly
closed.
NOTE:- HYDRAULIC POWER UNITS AND TOOLS SUPPLIED BY EHTMA MEMBER
COMPANIES CARRY RANGE IDENTIFICATION LABELS AND IT IS ESSENTIAL TO
CHECK THAT THE TOOL AND POWER UNIT HAVE THE SAME RANGE LABEL.
This code of practice applies to hydraulic power systems generally. Please ensure that
you have read and understood the manufacturers instructions before operating.

1) Ensure that the transmission hoses are positioned to avoid damage by vehicles etc.,
and that they will not be under strain when the accessory tool is in use.
ALWAYS USE SHARP STEELS - Blunt steels increase vibration and reduce efficiency.

Operating Instructions
STARTING THE BELLE HYDRAULIC POWER SUPPLY.
NOTE:- REFER TO THE ENGINE MANUAL FOR DETAILS. ALWAYS ENSURE
THAT THE BYPASS LEVER IS IN THE BYPASS POSITION.
Petrol Engines.
1)
Open the fule tap.
2) Close the choke on the carburetter.
3) Set the engine ignition switch to ‘ON’.
4) Start the Engine by pulling on the recoil starter rope.
5) As the engine warms up, gradually return the choke to ‘OPEN’.
NOTE:- MIDI AND MAJOR POWER PACKS ARE FITTED WITH A POWER ON
DEMAND DEVICE AND THE ENGINE WILL RUN AT IDLE SPEED UNTIL
PRESSURE IS GENERATED IN THE HYDRAULIC SYSTEM.
Diesel Engines.
1) Open the fuel tap.
2) Set the engine speed control to the ‘START’ position.
3) Set the decompressor lever to the ‘START’ position.
4) Start the engine by pulling the recoil starter rope.
OPERATING CHECKS.
Before commencing operation with the accessory tool, the following checks
should be carried out:1) Bypass lever is in the ‘FLOW’ position.
2) Ensure that there are no hydraulic leaks from hoses or couplings.
3) Check that there are no leaks from the breaker particularly between
joints, and at the nose end. Depending on the ambient temperature,
optimum performance is usually achieved after 5-10 minutes operation,
this is the time required for the hydraulic oil to reach its correct operating
temperature.
Operating Instructions
STOPPING THE BREAKER, 2012, 2025 and 3025.
1) Release the trigger to stop the breaker, remembering that the hydraulic supply
is still connected to the tool, and that the tool will work again when the trigger
is pressed.
2) Once the work period is complete isolate the breaker by moving the ‘BYPASS’
lever on the pack to the ‘BYPASS’position, and switch off the power pack as
detailed in the manufacturers instructions.
STARTING THE BREAKER, 2018, 2021 U/D, 2023, 2026 U/D, 2021X & 2025X
1) Ensure a comfortable operating position and that the cutting point is resting
on the surface to be broken.
2) Maintain a positive grip on the breaker handles and twist the trigger lock cam
away from you then press the trigger tostart work.
3) During breaking it will be necessary to move the cutting point to new
positions on the cutting surface, and Belle
recommend that the trigger is released during these manoeuvres. To restart
twist the trigger lock cam and press the trigger to start work again.
