Do’s and Dont’s
Do ensure the following are observed:
• The trolley should only be used by properly trained staff at all times.
• The trolley must be operated by 2 people when transporting a patient.
• When a patient is on board, the cot sides must be in an upright locked position before
moving the trolley or adjusting the trolley height.
• The trolley must only be used for the purpose for which it was designed.
• When disposing of the trolley, ensure that the hydraulic oil is drained and removed, and
disposed at an oil bank. In the UK find the nearest oil bank to you at: http://
www.oilbankline.org.uk/. For outside the UK check your governments guidance and
dispose of the oil appropriately.
Don't:
• lift the trolley upwards by the top.
• push the trolley over rough or uneven ground.
• drop heavy or sharp objects onto the solid plastic table top.
• push the trolley by the cot sides, these are for patient safety only.
• place a weight of over the equivalent of 34 Stone (220Kg/485lbs) onto the trolley.
• spill oil or other liquids/chemicals on the mattress.
• attempt to rectify any faults on the trolley without contacting Wardray Premise Ltd.
• use the trolley without a mattress.
• allow staff or patients to fix or store any items on the trolley unless you have verified the
MR safety of the items.
The trolley should be serviced regularly, but only by Wardray Premise trained
engineers, as they will carry the correct spares to guarantee safety and
compatibility of the trolley. Failure to comply with this will invalidate your warranty
and could compromise its MR compatibility and therefore safety.
Any serious incidents that occur in relation to this device should be reported to
Wardray Premise LTD and the competent authority of the member state in which
the user and/or patient are established.

General Maintenance
It is strongly recommended that the following checks are carried out on a weekly basis by
trained personnel, to ensure trouble free operation of the trolley.
• Check the solid plastic table top for cracks or other obvious signs of damage or
contamination. Report any damage found.
• Check mattress for any sign of damage or contamination. Report damage or clean where
necessary with mild soap and water.
• Check cot side covers for signs of damage, splits or tears.
• Check castors for free movement and the braking mechanism for functionality, check and
remove any debris that may have been caught between the forks and around the axles.
This is a common occurrence and can lead to a shortened life expectancy of the castor if
left unattended.
• Check the backrest function.
• Check the Trendelenburg function of the trolley.
• Particular attention must be made to the raise and lower function. Raise and lower the
trolley a couple of times before using, check for any leaks, especially if the trolley has not
been used for a long period of time.
• Check the cot sides for functionality and damage, especially the cot side brackets and
plungers, as these take the brunt of any impacts from the side. Ensure that the plungers
work freely and locate into the holes.
• Ensure that the IV Pole fitted is correct and the serial no. corresponds with the trolley serial
no. located on the inside of the backrest board (see page 5 for location). Make sure there
are no sharp burrs from misuse.
