Operation
CONNECTION TO HYDRAULIC POWER SOURCES
CHECK HYDRAULIC POWER SOURCE
•
Using a calibrated flow meter and pressure gauge,
make sure the hydraulic power source develops flow
and pressure that is appropriate for the ring saw.
•
Make certain that the power source is equipped with
a relief valve set to open at 2,500 psi/172 bar
maximum.
•
Make sure the ring saw is connected correctly to the
powerpack and that hoses are not leaking from
rubber or couplings.
CONNECTING HYDRAULIC HOSES
•
Wipe all hose couplers with a clean lint free cloth
before making connections. Do not connect pressure
to the return port.
•
Connect the hoses from the hydraulic power source
to the couplers on the ring saw hoses. It is a good
practice to connect return hose first and disconnect it
last to minimize or avoid trapped pressure within the
hydraulic motor.
•
Make sure the hydraulic hoses are connected
properly and fully seated to ensure that the flow is in
the proper direction. The female coupler on the
pump is the inlet (pressure) coupler.
Note: If uncoupled hoses are left in the sun, pressure
increase inside the hoses might make them difficult to
connect. Whenever possible, connect the free ends of the
hoses together.
General working Instructions
WARNING
•
Observe all safety precautions.
•
Never use the machine if you are tired, if you have
drunk alcohol, or if you are taking medication that
could affect your vision, your judgment or your co-
ordination.
•
Look around to ensure that no obstacles can affect
your control of the ring saw.
•
Do not use the machine in bad weather, such as
dense fog, rain, strong wind, intense cold, etc.
Working in bad weather is tiring and can lead to
dangerous conditions, e.g. slippery surfaces.
•
Never start to work with the power cutter before the
working area is clear and you have a firm foothold.
Look out for any obstacles with unexpected
movement. Ensure when cutting that no material can
become loose and fall, causing operating injury.
Take great care when working on sloping ground.
•
Be aware that your clothes or limbs have contact to
the moving parts on the ring saw or power.
•
Always keep a safe distance to the moving parts.
•
The guard protection of the spinning disc must
ALWAYS be in good condition and ALWAYS
mounted correctly.
•
Always have enough illumination for a secure
working environment.
•
Always ensure you are in balance and having a
good foothold when operating the ring saw.
•
ALWAYS check for hidden gas pipes or electrical
cables in the material you cut!
Cold Weather Operation
If the ring saw is to be used during cold weather, preheat the
hydraulic fluid at low power source speed. When using the
normally recommended fluids, fluid should be at or above
freezing level 32°F/0° C before use. Damage to the hydraulic
system or hydraulic motor seals can result from use with fluids
that is too viscous or thick.
Note: remember to empty the saw from water after cutting
in freezing conditions to avoid damage.
Equipment Protection and Care
•
Make sure all couplers are wiped clean before
connection.
•
The hydraulic circuit control valve must be in the
“OFF” position when coupling or uncoupling the ring
saw. Failure to do so may result in damage to the
quick couplers and cause overheating of the
hydraulic system.
•
Make sure the circuit PRESSURE hose (with male
quick disconnect) is connected to the “P” port. The
circuit RETURN hose (with female quick disconnect)
is connected to the opposite port. Do not reverse
circuit flow. This can cause damage to internal seals.
•
Always replace hoses, couplings and other parts
with replacement parts recommended by HYCON.
Supply hoses must have a minimum working
pressure rating of 3,040 psi/207 bar.
•
Do not exceed the rated flow or pressure (refer to
Specifications in this manual for correct flow rate and
pressure). If specifications are exceeded, rapid
failure of the internal seals may result.
•
Always keep critical labels and markings, such as
warning stickers and tags legible.
•
Ring saw repair should be performed by
experienced personnel only.
•
Make certain that the recommended relief valves are
installed in the pressure side of the system.
This section describes basic instructions on
how to use the HRS ring saw. If you feel
unsafe while operating the HRS ring saw,
STOP and seek expert advice. Do not attempt
to use the HRS ring saw any further until
instructions on how to proceed is given. Ask
specialist or your local HRS ring saw dealer.
