GB 1) The forward operating lever moves freely and does
not operate the mechanism : the machine has been
overloaded and the shear pin has sheared. See section
8.2 for replacing the shear pin (Jockey
2) Pumping :
A lack of lubricant in a machine sometimes brings about
a condition known as 'pumping' which is not at all dan-
gerous but which is inconvenient. This situation occurs
when the jaw which is gripping the rope becomes locked
onto it preventing the other jaw from taking over the
load. As the operating lever is moved in one direction

machine in reverse direction over a short distance to

3) Jerkiness :
This is also a symptom of lack of lubrication. The JOC-
KEY ™ machine should be thoroughly lubricated. Follow
the instructions for 'pumping' above.
4) Blockage :
If the wire rope becomes blocked in the machine, gene-
rally because a damaged section of wire rope is stuck
within the jaws, it is imperative to stop operating the
machine. The load should be taken by another machine
on a separate wire rope, or by another means, whilst
ensuring that all safety precautions are taken. When the
blocked machine is no longer under load, it may be relea-
sed and removed. Should this not be possible, return the
machine and wire rope to an approved repairer.
