HOSES AND FITTINGS
There exists the potential for shock in using anything other
than certified nonconductive hoses and hydraulic oil with
dielectric properties, when using system components near
energized electrical lines. Failure to recognize these conditions
could cause electrocution.
Hoses and fittings used with this tool must comply with S.A.E. J1273
which covers
recommended practice for selection, installation, and maintenance of hose and hose
assemblies. The
correct hoses and fittings are available from your supplier.
WARNING:
Failure to comply with these warnings could result in severe bodily injury.
WARNING
UNIT/HOSE CONNECTIONS
ALWAYS DISCONNECT
pump/power source and move toggle
switch to
OFF
before connecting or disconnecting any components.
ALWAYS DEPRESSURIZE
hydraulic system, before slowly
disconnecting this unit or any of the systems components.
ALWAYS TIGHTEN
couplings completely. Loose or improperly
tightened couplings will not allow fluid to pass through the
hose creating a blockage in the supply or return line.
ALWAYS INSPECT HOSES AND CONNECTORS
before
connection to tool. Replace or repair if any leakage is evident.
Leakage is a sign of deterioration in component parts. Worn or
leaking parts must be repaired or replaced, or tool damage or
severe injury could result.
WARNING
HOSE INSTALLATION
ALWAYS ENSURE CONNECTORS ARE CLEAN
DOUBLE ACTING
- Care must be taken to assure the correct
connection of the hoses to the pressure and return (tank) ports.
Connect the return hose to the return (tank) port on the power
source, then to the return port on the tool.
Connect the pressure hose to the pressure port on the tool,
then to the “P” pressure port on the power source.
Operation with hydraulic flow reversed can cause malfunction.
SINGLE ACTING
- Connect the pressure hose to the pressure
port on the tool, then to the “P” pressure port on the power source.
Failure to fully comply can result in severe injury or death.
