•
Check for any visible damage of electrical or mechanical parts.
•
With Actuators fully extended, clean the back rest and knee break actuator shafts
with a soft, dry cloth.
•
Check all electrically controlled functions.
•
Check wheels for damage and brake lock function.
•
Raise and lower the bed fully, then tilt the bed fully in both directions. Listen for unusual
noises in the mechanism and watch for ‘jerky’ action. Call for maintenance personnel if
anything unusual is discovered.
•
If fitted with battery back-up, check that the battery is charged and able to operate
the bed.
Every 12 Months
•
Remove the mattress from the bed. With the bed 100mm raised from its lowest height,
remove the column covers. Carefully examine the lifting screw for wear. Replace linear
actuator if faulty or screw is worn.
•
Check mains cable, ensure there are no breaks in the lead and the strain relief is intact.
•
Check all wiring for kinks, damage, dislocation or worn insulation. Replace where
necessary.
•
Operate all controls of the bed through the full movement of each function. Listen for
noise in the bearings and ensure the operation is smooth.
•
Check the wear on back rest and knee break pivots. Replace pivot bolts if they appear
worn.
•
Any pivot bolts attached to the ends of the actuators must be fitted with new nyloc nuts
if nuts are removed. The nuts must not be tightened against the clevis - leave about 1mm
of side play.
•
Look closely at all welds, especially around the backrest and knee break actuator
connections. Overloading may cause these welds to crack. Replace any faulty
components or send the bed for repair.
•
Check all wheels for wear, flat spots or damage.
•
Check for correct castor brake function.
•
Check for damage to paint work or significant rusting. Repair where necessary.
•
Check mattress base sheets for signs of wear and looseness. Replace bolts where
necessary.
ROUTINE MAINTENANCE
