SAFETY PRACTICES
CAUTION!
Do not operate motor at relief pressure! The motor should not be
operated for more than a few seconds when the unit is operating at relief
pressure. Longer running times could result in damage to the pump.
CAUTION!
Automatic cylinder retraction possible! Be aware that the cylinder rod
may retract into the cylinder body automatically when the hydraulic hose is
disconnected.
CAUTION!
Avoid air in the system! The presence of air in the system can lead to a
lock-up of the velocity fuses. (Air reacts like a spring when it is
compressed.)
CAUTION!
Protect cylinder rods, hydraulic ports and lines at all times! Welding
splatter and dust from grinding operations can cause severe damage to
this equipment.
CAUTION!
Do not damage the pump or motor! If the motor needs to run during the
installation process and the electrical work is not complete, only do so for a
second or two after the mechanical stop is pressed. Longer activation
could cause damage to the pump or the motor. If the electrical control
system is complete, the motor will stop because of the pressure switch
setting.
