Set the operating table surface as low as possible while transporting to ensure transport comfort. Transport
the operating table with the leg section at the front. Remember the directional castor!

Note! If the operating table surface is not raised high enough when the leg section is dropped into its lowest
position, it may impact with the table base casing damaging the operating table and creating pinching
hazard.

4. MAINTENANCE AND R EPAIR

4.1 Maintenance procedures

We recommend the following advance check-up and maintenance procedures to ensure continued
maintenance and trouble-free operation.

4.1.1 Daily maintenance

• During normal cleaning of the table, make a general visual inspection to ensure that it is in proper

working order.

• The PRACTICO Operating Table must be cleaned after each surgical procedure.

• We recommend that the batteries be charged every day. This will ensure a sufficient battery charge

and long service life

!

!

4.1.2 Monthly maintenance

• Lubricate all tabl e jo ints with lig h t mach in e oil .

• Ensu re tha t all cas tors roll eas il y and lock secu re ly.

• Check all table functions by fully extending and retracting them.

• Ensure that motor-equipped back sections are properly mounted to the seat. If necessary, tighten the

locking screws. See section 4.9 page 26.

• Ensure that the accessory rails are properly mounted.

4.1.3 Annual maintenance

• Perform all the same inspections as in monthly maintenance.

• Check and adjust column clearance, if required.

• Check cables and their connections.

All electrical repairs must be performed by a licensed electrician.

Before pe rform in g ma in te na n ce proce d ure s :

• Disconnect power supply

4.2 Troubleshooting and checklist

When troubleshooting, check the following items first:

• Does the malfunction affect all table functions?

• Does the malfunction only affect one control function?

• If the problem on ly affe cts one control fu nction , d oes it do so in b oth di rection s ?

• Is the malfu n ction tha t the tabl e doe s n ot move or that it will not main tai n its po si tion?

The following components are common to all systems. If there is a malfunction in these, all control functions
will be affe cted .

• Control unit

• Hand control unit

• Battery

• Power source/battery

If there is a malfunction in one of the following components, it usually affects only one function.

• Motor

• Gas spring

Malfunction Cause

Table adjustments do not function. • Switch is in STAND BY position

• Hand control is unplugged

• Battery is dead

• Fuse is blown

• Faulty hand control

• Faulty control unit

Table functions are sluggish and weak. • Low battery charge

•Faulty motor

Operating table function duration is short, even
though the battery has been charged in accordance
with instructions.

Castors ma k e ab n orm al nois e s wh en rolling • Pedal in wron g po si tion

• Faulty charger

• Faulty battery

• Battery too old

• Castor bearings worn
