6.0 Operation – [cont’d]
CAUTION
The Breaker is not designed to lift or transport loads.
This practice is unsafe and can damage the
Breaker.
6.3.5 Do Not Operate Breaker with Cylinders at
Stroke End
Operating the breaker with the cylinders fully
extended or retracted can damage cylinders.
Fig 6-10 Do not Operate with Cylinders at Stroke End
6.4 Special Applications & Operating Conditions
6.4.1 Working Underwater
CAUTION
Serious equipment damage may result if proper
procedures are not followed. Never submerge the
Breaker in water without proper equipment
modifications and training.
Fig 6-11 Not Underwater Ready - Modifications Are
Required
Working underwater requires special preparation to
avoid damaging internal components, including the
piston and seals. Additional equipment and training is
required. Further instructions should be directed to
the Allied Technical Service Department.
6.4.2 Working Underground
When using the Breaker underground [tunneling or
mining applications] special safety regulations may
apply. Additional considerations include:

Use of water sprays to suppress dust.

Use of fire-resistant hydraulic fluids. Hydraulic
systems using fire-resistant fluids require special
engineering consideration when using the
Breaker. With some fluids, decreased flow and/or
pressure to the Breaker may be necessary.
6.4.3 Working in Hot Temperatures
IMPORTANT
Serious equipment damage may result if proper
procedures are not followed. Check the oil
temperature often to ensure it does not exceed
176ºF [80ºC]. If higher temperatures are
measured in the tank, refer to the
Troubleshooting Section in this manual.

Specify hydraulic oils with viscosity suitable for
the climate conditions. In general, the hydraulic
oil that was originally specified for the machine by
the carrier manufacturer can be used with this
equipment.

Check the oil level in reservoir

Inspect the cooling system. Good air circulation is
essential in dissipating heat from the hydraulic
oil. Make sure the cooler is clean.
6.4.4 Working in Cold Temperatures
IMPORTANT
Serious equipment damage may result if proper
procedures are not followed. When working in
temperature conditions below minus 4ºF [-20ºC],
operating the Breaker with cold hydraulic oil may
damage the seals.

At temperatures below minus 4º F [-20º C], the
hydraulic oil must be warmed up before starting
the Breaker. Follow instructions provided by the
carrier manufacturer for on warming up the
carrier.
