The ram should only be extended hydraulically; it should never be pulled out by hand or used to
carry the jack.
Do Not position the jack by using the operating lever in the release valve. If the jack is t o be
placed some distance under the load, use the operating lever in the operating lever/quadrant
socket to position the jack.
Do Not drop loads onto the jack. If the jack is inadvertently subjected to a shock load, remove
from service and have it checked by a competent examiner or service agent.
Do Not overload the jack especially when lowering loads.
Do Not under any circumstances go under a load when hydraulic jacks solely support it.
If using more than one jack, all the jacks must be able to individually raise the load e.g. two
PS620 jacks cannot be used to lift a 30T load as it impossible to pump both jacks at exactly the
same rate, or lower the jacks at exactly the same rate, one of the jacks will end up with an excess
load and is liable to fail. In such case two PS630 jacks should be used to raise a load of 30T.
Operating Environments
The jack is intended for use in industrial environments, inside or outside, between
temperatures of –20 to +50°C. Outside these limits, or in explosive atm ospheres/areas of
nuclear radiation, consult the manufacturer before use.
Noise and Vibration
By its design, the jack operates slowly under manual eff ort. There is no noticeable noise or
vibration.
