CAUTION
Obstructions during extending and lowering can lead to squeezing!
Squeezing danger: During lowering the piston rod will accelerate by applied forces.
High force and high speed can develop.
5. TROUBLESHOOTING
DISTURBANCE CAUSE SOLUTION
Short-term pressure build
up only
Over travel of the overflow Operator tries to create tension with far
extended piston rod.
Max. stroke reached The overflow is over traveled during
pressure build up. This results in an
immediate pressure loss. The piston
rod travels the length of the excess
to the overflow back, about 2 mm.
Pressure will not build up Safety valve is responding Ensure intended use!
Hydraulic unit polluted Keep the lowering valve open and try
pumping several times.
Repeat this procedure several times.
Pumping jerkily with open and closed
lowering valve. Produce strong internal
oil flow to flush pollutants of the valve
seating.
Repeat this procedure several times.
Unit does not hold the
pressure
Drain valve not fully closed Check drain valve if contamination
prevents complete closing.
