Joerns Healthcare Ltd recommends the Oxford Up and its accessories are subjected to inspection and
maintenance, as detailed in this manual, at appropriate intervals depending on a risk assessment of the
frequency of use and environmental factors. This will ensure the equipment is adequately maintained and
remains safe for use as detailed in PUWER (Provision and Use of Work Equipment Regulations). The risk
assessment is necessary as PUWER does not detail specic time intervals.
WARNING
OXFORD RECOMMENDS THE USE OF GENUINE OXFORD PARTS. Oxford sling/belt and products
are designed to be compatible with one another. For country specific guidance on sling/belt use
and compatibility, please refer to the sling/belt label or contact your local market distributor or
Joerns Healthcare.

NOTE: Before applying medium strength removable threadlock to any screw or bolt, ensure it can be
screwed into the component without hindrance from old remaining threadlock as this could a󰀨ect the
correct torque setting.

2. Carefully position the leg operating mechanism assembly in the central position to enable access to
the M8 securing screws. See gs. 2 and 3.
3. Once the leg mechanism is re-assembled into the chassis, ensure the M8 mechanism block securing
screws are tightened securely to 20Nm.
