PROBLEM
CAUSE
SOLUTION
Cylinder(s) will not retract or
extend.
1. Quick disconnect couplings
are not completely coupled.
A Double acting cylinder
or ram must have
both
hoses and all couplers
securely connected to
both ports. If one of the
two ports is restricted or
becomes disconnected,
pressure will build and
the cylinder, hose or
coupler can burst,
possibly causing serious
injury or death.
1. Check quick disconnect
coupling to cylinders to
ensure that they are
completely coupled.
Occasionally couplers have
to be replaced because the
ball check does not stay
open due to wear.
2. Broken return spring in
spring return cylinder or
seals blown in double-acting
cylinder.
2. Contact a Power Team
Authorized Hydraulic
Service Center.
Pump delivers excess oil
pressure.
1. Faulty pressure gauge.
1. Calibrate gauge.
2. Relief valve not properly
set.
