To reduce the risk of serious injury or death to yourself or others, before operating the machine, read the Safety instructions section
found on the previous pages of this booklet.
Design and Function
The Belle Group BHB Range of handheld Hydraulic Breakers are sturdy and reliable breakers designed for working together with Belle
Group Hydraulic Power Packs.
The handheld Breakers are available in many different sizes with varying impact energies and commonly used tool sizes. The handheld
Breakers are designed for various jobs from light brickwork and asphalt jobs to heavy duty jobs in reinforced concrete.
All Belle Group BHB Range handheld breakers are delivered with ½" tail-hoses with ½" Flat-Face quick-release couplings for easy
connection to the Belle Group Hydraulic Power Packs.
Choosing the correct hydraulic breaker for a task
It is important to choose the correct size of hydraulic breaker for the work to be performed.
A hydraulic breaker that is too small means that the work will take longer.
A breaker that is too big means that there must be frequent repositioning, which is unnecessarily tiring for the operator.
A simple rule for choosing the correct size of hydraulic breaker is that a normal sized piece of broken material should be removed from
the workpiece within 10–20 seconds of operation.
•
If it takes less than 10 seconds a smaller hydraulic breaker should be selected.
•
If it takes more than 20 seconds a larger hydraulic breaker should be selected.
Installation
Hoses
For connection of the breaker, the hydraulic hose must be approved for a working pressure of at least 200 bar (2900 psi) and have a
½" inner diameter. To resist exterior wear and tear, we recommend using a 2-layer hydraulic hose. The breaker connection marked P
(pump) is oil inlet, and the connection marked T (tank) is oil outlet.
Quick-release couplings
The original Belle Group hydraulic hoses are ¿ tted with Flat-Face quick-release couplings that are strong and easy to clean. The quick-
release couplings are ¿ tted so that the male connection supplies oil and the female connection receives oil.
Fitting and Removing the Breaker 'Steel'
Whenever ¿ tting/removing the 'Steel', the following instructions must be observed:
1) To prevent an accidental start, switch off the oil supply. Bleed the machine by pressing the
start/stop device. Disconnect the machine from the power source.
2) Remove the 'Steel' by swinging the latch (C) fully down (Image A).
3) Fit a 'Steel' by ensuring that the latch (C) is fully down. Then insert the 'Steel' in the breaker
as shown and swing the latch (C) fully up (Image B).
Operating Instructions
Checking for wear
2
Using a working tool with a worn out shank leads to increased machine
vibrations. To avoid increased vibrations, check the shank for wear before the working
tool is ¿ tted in the machine.
Use the checking gauge that corresponds to the working tool's shank dimension. If the
gauge's hole (2) can be pushed down on the working tool's shank, this means that the
shank is worn out and the working tool should be replaced.
* Note:- The Checking Gauge is not supplied with the machine.
