Safety and operating instructions

Overview

To reduce the risk of serious injury or death
to yourself or others, read the Safety
instructions section found on the previous
pages of this manual before operating the
machine.

Design and function

Handheld hydraulic breakers are sturdy and reliable
breakers designed for working together with Chicago
Pneumatic hydraulic power packs or, by means of
a Chicago Pneumatic OFD oil flow divider, with most
hydraulic excavators, backhoe loaders and tractors.
There are no limitations on the ambient temperature
at the work place as long as the hydraulic fluid used
keeps within its operational parameters.
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. No other use is permitted. To choose the
correct insertion tool, see the spare part list or
accessories catalogue.
All handheld breakers are delivered with tail-hoses
with Flat-Face quick-release couplings for easy
connection to the Chicago Pneumatic power packs.

Choosing the correct
breaker for a task
It is important to choose the correct size of breaker
for the work to be performed.
A breaker that is too small means that the work will
take longer.
A breaker that is too large means that there must be
frequent repositioning, which is unnecessarily tiring
for the operator.
A simple rule for choosing the correct size of breaker
is that a normal sized piece of broken material should
be removed from the workpiece within 10–20
seconds operation.
> If it takes less than 10 seconds a smaller breaker
should be selected.
> If it takes more than 20 seconds a larger breaker
should be selected.

Labels

The machine is fitted with labels containing
important information about personal safety and
machine maintenance. The labels must be in such
condition that they are easy to read. New labels can
be ordered from the spare parts list.
