WARNING
OXFORD RECOMMENDS THE USE OF GENUINE OXFORD PARTS. Oxford slings and lifters are not designed to be interchangeable with other manufacturer’s products. Using other manufacturer’s products on Oxford products is potentially unsafe and could result in serious injury to patient and/or caregiver.

Load Testing

The load test should be carried out in accordance with the manufacturer’s test procedures and the directive detailed in EN ISO 10535:2006 – Annex B – Periodic Inspection B1 – see excerpt below. It is strongly recommended that an authorised service dealer carry out the test.
EN ISO 10535:2006
Annex B
(Informative)
Periodic Inspection
B. 1 Periodic inspection of the hoist should be undertaken at the time intervals stated by the manufacturer, but at least once a year. By periodic inspection is meant a visual examination (particularly of the hoist’s load bearing structure and lifting mechanism with attachments, brakes, controls, safety devices and person-support devices) and whatever function tests and maintenance measures may be required, e.g. adjustment of brakes, tightening of fasteners.
Every inspection should include a working load test of one (1) lifting cycle with the maximum load.
Oxford Electric hoists have been designed to the requirements of:

1. BS EN ISO 10535 2006 Hoists for the transfer of disabled persons
   The hoists are designed to lift the Safe Working Load only. The load lifting capability is set electronically and must not be increased as this causes excessive loading when the actuator reaches the limits of travel. This will afect the actuator’s useful life.

2. BS EN ISO 10535 Load Raising Test
   This test is a straightforward lift of a load the equivalent to the Safe Working Load from the lowest position to highest position of the hoist. Check that the hoist is not capable of lifting much more than the Safe Working Load (A small additional lifting capability is allowable but no more than 15% of the SWL).

3. BS EN ISO 10535 Operator efort Test
   This test is conducted with the Safe Working Load only.
   Using a force gauge (0-500N is a suitable range) push the one of the foot pedals down and note the amount of force necessary to open or close the legs. Maximum permissible force is 300N (30 kgf / 67 lbf).

Checking Welds For Fractures
NOTE: During the load testing procedure, while the lift is loaded with the safe working load, check ALL welded joints on the lift for signs of fracture. If fractures are evident, the lift should be taken out of service and not used until damaged components of the frame are replaced.
Test Loads – Oxford Advance
SWL 155kgs/342lbs.
NOTE: The load for calibrating the service monitor is 126kg.
The load test should be carried out in accordance with the manufacturers test procedures. It is strongly recommended that an authorised service dealer carries out the test.
Certification
An authorised service dealer will issue a test certiicate after satisfactory completion of the thorough inspection and test. This certiicate will be valid for six months.
Thorough Examination Report
Lifting Operations and Lifting Equipment Regulations 1998 (LOLER UK ONLY)
LOLER requires certain information to be included on the report given to a customer after a thorough examination. The information can be found in Schedule 1 (page 59) in the LOLER L113 publication.
Joerns Healthcare Ltd has prepared a Thorough Examination Report that includes all the required information and a copy can be found later in this manual. Please feel free to use this as the basis of your own report.

2. Ensure the castors swivel and the wheels rotate freely. If the free rotation of any castor is afected by threads, hairs or ibres the castor should be replaced as these are non-serviceable components.
3. To remove a loose or damaged castor, irst remove the two M6 button head screws under the leg that secure the front leg insert.
4. Pull the insert out of the leg and push the rubber protective jacket (it may require a tap with a soft mallet from the back to loosen it) down the castor housing insert far enough to enable the castor nut to become accessible to a 21mm A/F Spanner (supplied) and remove the castor.
5. Re-assemble with thread lock. Tighten to 10Nm.
6. Check all four castors are seated irmly on the ground.

NOTE: Before applying thread lock to any screw or bolt check, it can be screwed into the component without hindrance from old remaining thread lock. This could afect the proper torque setting.

Leg Locking Mechanism – Inspection and Re-Assembly

When inspecting or re-assembling either the leg locking knob or leg locking mechanism, see Fig 1 & 2, on the Oxford Advance lift, it is imperative to ensure the legs open and close correctly when the foot pedals are operated.

When re-assembling the leg locking knob to the M10 threaded steel shaft, ensure it is ONLY tightened to the position where the rear of the knob moulding just contacts the adjacent base casting of the lift, see Fig 3.
Once the correct positioning of the knob is achieved, securely tighten the M4 x 5mm grub screw, see Fig 4.
WARNING
If the leg locking knob is continually tightened after contacting the base casting, it could compromise the engagement of the leg locking mechanism, See Fig 5 & 6, and in extreme circumstances, the legs may close without warning and jeopardise the safety of the patient/care giver.
