Load Testing (Electrical Variants Only)
The load test should be carried out in accordance with the manufacturers 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 lifts 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 a󰀨ect the actuator’s useful life.
2 BS EN ISO 10535 Load Raising Test
This test is a straight forward lift of a load 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 should be no more than
15% of the SWL).
3 BS EN ISO 10535 Operator E󰀨ort Test
This test is conducted with the Safe Working Load only.
Using a force gauge (0-500N is a suitable range) push the foot pedals down and note the amount of
force necessary to open or close the legs. Maximum permissible force is 300N (30kgf / 67lbf).
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.

Oxford hydraulic lifts 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.
2 Load Raising Test
This test is a straight forward lift of a load the equivalent to 125% of the Safe Working Load from the
lowest position to highest position of the hoist.
3 BS EN ISO 10535 Leak Test
This test is conducted with a load the equivalent to 125% of the Safe Working Load. With the hoist
in the highest working position, the hoist must maintain the lift for 15 mins. The maximum downward
movement of the hydraulic pump ram must not exceed 3mm over the 15 mins.
4 BS EN ISO 10535 Operator E󰀨ort
This test is conducted with the SWL only. Attach a spring balance (0-20 kg is a suitable range) to
the end of the crank handle and note the amount of pull necessary to operate the handle stroke.
Maximum permissible force is 120N (12.25 kg / 27 lbs).
5 BS EN ISO 10535 Descent Test
This test is conducted with the SWL only. Take the test load to the highest operating position and
measure the height of the weight from the oor. Open the release valve 1/8th of a turn. With a
stopwatch, time the descent until the weight is just clear of the oor. Stop the watch and close the
valve at the same time. Measure the distance travelled by the weight. The rate of fall must not exceed
108mm/second. Return the weight to the highest position and check that the speed of descent
increases as the valve is progressively opened.
6 BS EN ISO 10535 Operator E󰀨ort Test
This test is conducted with the SWL only. Using a force gauge (0 - 500N is a suitable range), push
the foot pedals down and note the amount of force necessary to open or close the legs. Maximum
permissible force is 300N (30 kg / 67 lbs).
7 Horizontal Boom Test
This is not a requirement of BS EN ISO 10535 but is required by users and specied by Joerns Healthcare.
With the release valve closed, pump up the unit until the boom is horizontal. Fully open the release valve.
Check: The boom must remain in the horizontal position and not descend under its own weight. Conrm the
boom will descend when additional pressure is applied by hand to the end of the boom.

assembly. Ret the retaining “O” ring. Check rotation of the pivot in the boss.
3Replace the padded rubber moulding.
4Position the boom end cap over the spreader bar central pivot ensuring the holes align with the holes
in the central pivot.
5Insert the boom end cap/spreader bar assembly into the boom end ensuring the holes in the boom,
boom end cap and spreader bar central pivot point are aligned. NOTE: It is suggested a drift or 6mm
hex key are inserted through the holes in the boom, boom end cap and spreader bar central pivot to
ensure all holes are aligned.
6 Ensure the one circlip and plastic retaining washer are tted to the one end of the fulcrum pin.
7Insert the spreader bar fulcrum pin through the holes in the boom, boom end cap and spreader bar
central pivot, pushing the drift out in the process.
8 Re-t the plastic retaining washer to the fulcrum pin.
9 Fit a new retaining circlip to the fulcrum pin and ret the plastic protective cap. WARNING: Once the
circlip is tted in position, ensure it has not become deformed or over-expanded during the
tting process. If it has, it must be replaced.
WARNING: Following re-assembly of the spreader bar to the boom, it is critical that the underside
of the boom/spreader bar is carefully examined to conrm the spreader bar fulcrum pin has been
correctly inserted through the holes in the boom, boom end cap and spreader bar central pivot.
Failure to do so could result in serious injury or death.

Boom
1 Ensure there is no excessive side movement of the boom and that it is centred and free to rotate.
NOTE: Due to the characteristics of the mast/boom pivot joint, up to 25mm total side movement
measured at the spreader bar end of the boom can be expected (under light sideways pressure).
Movement exceeding this gure should be investigated.
2 Check for wear and security of the actuator mounting.
3Lubricate the mast/boom pivot and actuator fulcrum pin with a light mineral based grease or food
grade spray lubricant.
4Check the mast/boom pivot is fully tightened using a 5mm hex key.
5If the mast/boom pivot is not fully tightened, remove the grey decorative inserts and dismantle the
mast to boom fulcrum pin using a 5mm hex key. Examine the fulcrum pin for signs of wear. The
fulcrum pin in 12mm in diameter. Reduction in diameter due to wear should not exceed 1mm
before replacement.
6 If the mast/boom pivot does not display signs of wear, apply medium strength thread lock (blue) to the
fulcrum pin securing screws prior to assembly. Re-assemble and tighten to 25Nm.
7Examine the actuator mounting point. Without taking the mounting apart check for signs of wear on
the fulcrum pin. Check for excessive vertical and horizontal movement in the mounting. This will give a
good indication of wear but if there is any doubt the assembly should be stripped down as follows:
8Remove one of the circlips that secures the actuator fulcrum pin to the bracket and extract the fulcrum pin.
9 Examine the fulcrum pin for signs of wear and for rm attachment of the remaining circlip. The
diameter of the fulcrum pin is 10mm. Reduction in diameter due to wear must not exceed 1mm
before replacement.
10 Examine the actuator mounting on the boom for wear on the bore of the bracket. Wear should not
exceed 2mm.
11 Examine the actuator top mounting boss for wear/security. Wear should not exceed 1mm.
12 Lubricate the fulcrum pin using a light mineral based grease or food grade spray lubricant.
13 Replace the fulcrum pin through the actuator and boom bracket.
14 Fit a new circlip to the fulcrum pin.
NOTE: Joerns Healthcare recommends the following:
• NEVER reuse circlips.
• ALWAYS use circlip pliers for tting.
• ENSURE the circlip is properly located in the groove and not deformed.
Mast/Boom Pivot
1Check the pivot for lateral, vertical and horizontal play that would indicate excessive wear. Signs of
excessive wear must be investigated and the pivot stripped down. Lateral play at the pivot point
must not exceed 1mm before replacement.
2 Construction of the mast/boom pivot comprises of 11 components: 2 o󰀨 self adhesive screw covers,
2 o󰀨 M8 x 20mm counter sunk head screws, 2 o󰀨 25mm counter sunk steel caps, 1 o󰀨 12mm inner
fulcrum pin and 1 o󰀨 19mm outer sleeve, 2 o󰀨 plastic pivot bearing washers and 1 o󰀨 pivot casting.

Removal of the Mast/Boom Pivot
1 Remove the 2 o󰀨 self-adhesive screw covers.
2The mast/boom pivot fulcrum pin is held in place with two M8 x 20mm counter sunk head screws.
Remove one of the screws from the fulcrum pin and leaving the other in place, withdraw the fulcrum pin.
3 Examine the fulcrum pin for signs of wear and for rm attachment of the remaining screw. The
diameter of the fulcrum pin is 12mm. Reduction in diameter due to wear must not exceed 1mm
before replacement.
4Withdraw the outer sleeve bush from the boom end (hold the boom while doing this as it may fall
forwards). Inspect the sleeve for wear as per the fulcrum pin.
5 Remove the plastic bearing washers (2 o󰀨) from the pivot and examine for any wear or damage.
Lateral movement at the pivot is most likely to be caused by wear on these washers.
6Examine the through holes in the mast and the boom end for wear or damage. The bore and holes
are 19mm in diameter. Wear should not exceed 1mm on diameter or 2mm elongation before
replacement.
Re-Assembling the Mast/Boom Pivot
After performing all the actions and checks in the previous section, reassemble the Mast/Boom pivot as
follows:
1Lubricate the fulcrum pin and sleeve with any light mineral based grease or food grade spray lubricant,
paying particular attention to the bearing washers and the mast/boom pivot internal bore.
2Insert the 19mm outer sleeve into the through hole in the boom end.
3Position the boom between the mast pivot brackets.
4Position one of the plastic pivot bearing washers between the boom and the mast pivot bracket,
ensuring the holes in the mast pivot bracket, the plastic bearing washer and the boom outer sleeve
are aligned.
5 Insert the fulcrum pin with the 1 o󰀨 counter sunk steel cap and the 1 o󰀨 M8 x 20mm counter sunk
head screw still assembled, through the mast pivot bracket, a plastic bearing washer and boom outer
sleeve until it is inside the boom outer sleeve but does not protrude.
6Whilst supporting the boom in the mast pivot bracket, position the second plastic bearing washer
between the boom and the mast pivot bracket, ensuring the hole in the washer aligns with the holes in
the boom outer sleeve and mast pivot bracket.
7Further insert the fulcrum pin so that it passes through the plastic bearing washer and the mast pivot
bracket.
8Assemble the remaining 25mm diameter counter sunk steel cap to the remaining M8 x 20mm counter
sunk screw.
9Apply medium strength thread lock (blue) to the thread of the M8 x 20mm counter sunk screw.
10 Assemble the M8 x 20mm counter sunk screw to the fulcrum pin and tighten using a 5mm hex key to 25Nm.
11 Fit replacement self adhesive screw cover to the heads of the M8 x 20mm counter sunk screws.
NOTE 1: Joerns Healthcare recommends the following:
• NEVER t a new fulcrum pin or sleeve to a worn or damaged boom.
• ALWAYS tighten the fulcrum pin to the correct torque setting.
• ALWAYS assemble the M8 screws with thread lock.
• CHECK the assembled Mast/Boom pivot for unacceptable movement.
NOTE 2: Before applying thread lock to any screw or bolt, check it can be screwed into the

Mast
1 Make sure the mast is fully engaged into the mast socket.
2 Check for presence of the mast ‘fool proong’ pin.
3Check the operation of the mast locking device.
4Check the security of the actuator unit mounting and lubricate with a light mineral based grease or
food grade spray lubricant.
5 Examine all the welded joints on the mast fabrication for hair-line cracks, paying particular attention to
the joints between the positioning handles and the mast and the mast pivot brackets to the mast.
6Examine the actuator mounting point for damage or wear. Without taking the mounting apart check
for signs of wear on the fulcrum pin. Check for excessive vertical and horizontal movement in the
mounting. This will give a good indication of wear but if there is any doubt the assembly should be
stripped down as follows:
7Remove one of the circlips that secures the actuator fulcrum pin to the bracket and whilst supporting
the boom/actuator, extract the fulcrum pin.
8 Examine the fulcrum pin for signs of wear and for rm attachment of the remaining circlip. The
diameter of the fulcrum pin is 8mm. Reduction in diameter due to wear must not exceed 1mm
before replacement.
9Examine the actuator mounting bracket on the mast for wear on the bore of the bracket. Wear should
not exceed 2mm.
10 Examine the actuator bottom mounting boss for wear. This should not exceed 1mm.
11 Lubricate the fulcrum pin using a light mineral based grease or food grade spray lubricant.
12 Replace the fulcrum pin through the mast bracket and actuator.
13 Fit a new circlip to the fulcrum pin.
NOTE 1: It is most important that fulcrum pins are re-assembled carefully. Check to ensure
complete security.
NOTE 2: Joerns Healthcare recommends:
• NEVER reuse circlips.
• ALWAYS use circlip pliers for tting.
• ENSURE the circlip is properly located in the groove and not deformed.
14 Conrm the presence and proper location of the mast engagement label.
15 Check the correct operation of the mast-locking knob. Conrm the mast will lift from the mast socket
when the locking knob is unscrewed.
16 Check the presence and condition of the positioning handle end caps and replace if necessary.

Battery Pack & Control Unit (Electric Variants)
1 Conrm the mounting bracket is rmly attached to the mast. Three no. 2 pozi drive head screws
secure the mounting bracket. Conrm the screws are fully tightened to 5Nm.
2Check the engagement of the battery pack with the mounting. The battery pack should snap into place
and be retained by a latch at the top of the pack. Make sure the latch is functioning correctly and holds
the battery pack rmly in place.
3Check that the actuator and hand control plugs are inserted fully into the appropriate socket on the
base of the control unit. The plugs, particularly the hand control plug, are a tight t in the sockets and
must be pushed fully home. The hand control plug is indexed and can only be tted in one position.
The ‘raise/lower’ actuator plug is not indexed and can be tted with a straight push. The ‘raise/lower’
actuator jack plug connects to the socket marked ‘1’ in the base of the control box.
4Inspect the hand control and coiled lead for any obvious signs of damage. Damage to the hand control
and particularly to the lead can cause intermittent faults. The hand control should be replaced if
damage is evident.
5 Check the operation of the hand control. Press the raise and lower buttons and conrm the boom
moves in the correct direction.
6Check the operation of the Emergency stop switch. Push in the red button; this will latch and remain
depressed and cut o󰀨 all power to the lift. Conrm by looking at the LED panel that should now be
blank. Conrm the boom does not operate when depressing the raise and lower buttons on the hand
control. Return power to the lift by twisting the red button clockwise and releasing. The LED panel
should no longer be blank and battery power should now be displayed instead.
7 Check the operation of the redundant control raise and lower buttons. These are two raised ‘soft push’
buttons on the front of the control unit under the Emergency stop switch identied by up and down
arrows.
