1.0 PRELIMINARY INFORMATION

WARNING

Before servicing this operation table the

engineer should be familiar with all the

warnings and cautions contained within the

‘Instructions for use’ detailed in section 1.1.

This service manual does not provide details

of how to operate the table nor does it provide

information on the symbols and warning signs

provided on the table. All this information is in

the‘Instructions foruse’supplied withthe table.

Additional copies of the ‘Instructions for use’

can be obtained from Eschmann Equipment.

Only qualified and trained engineers should

service or maintain this operation table to

ensure that all the built-in safety features are

not compromised.

The number in brackets above, is the part number for that

publication.

1.2 ‘Instructions for use’ and ‘Service manuals’ should

be readily accessible for reference prior to and when

operating,cleaning,servicing,or,maintaining the operation

table.

1.3 Thetable and allaccessories arenot suppliedsterile

therefore the table and all accessories should be cleaned

and disinfected in line with hospital practice and the

informationsuppliedinthe‘Instructions for Use’beforeuse.

1.4 The manuals listed above and the Application

software,areavailabletoorderfromEschmannEquipment,

see inside front cover for address details.

1.5 Make sure that routine servicing is carried out as

detailedinthe serviceschedule,section5.4,by Eschmann

trained or accredited engineers.

1.6 Theservice scheduleprovided inthis manualdetails

a program of maintenance work to be carried out at six

monthly intervals, refer to the applicable section of this

manualfordetailsofhowtoperformthese variousfunctions.

Any special adjustments required for components are

detailed in the part replacement (section 6.0) for that item

tosaveduplication.Asroutinethe Service Scheduleshould

be followed in the event of an additional service due to a

faultdevelopingwithanyaspectofthe table, thiswill ensure

that all aspects of the table are covered.

WARNING

Ensure that the correct screw torque settings

are used as detailed within this manual to

ensure safety and that parts are not damaged.

1.7 Throughout this manual there are recommended

torque settings for many of the screws. In the main, these

are only provided on the illustrations. Ensure that these

arecheckedandthecorrecttorquesettingsare used where

specified.These areprovidedtoensure safety(i.e.screws

are tightened correctly) and that components are not

damaged by excessively high torques.

1.8 Fig. 1.0 identifies the main parts of the T20-a

operationtable.

1.9 The tablecanbeplacedinto a ‘ServicePosition’that

provides easy access to components within the ‘top of

column’area (ensuretableis switched‘off’beforeopening

top). To achieve this position first note the safety warning

insection 4.1.Removeasmuch aspossiblefromthe table

top (e.g. leg and head sections, accessories and

mattresses etc.). Remove the top of column steel covers

(items13 and 14ofFig.6.1). RemovethefourM10 screws

(each side) that secure the trunk sections to the pedestal

(not the M6 cap head screws that can be seen passing

throughthe oilitebushesoneach side)andallow thetrunk

section to pivot (short trunk down) about the oilite bush

pivots(item 16, Fig.6.3).Extreme careshouldbe takenat

all times with the table in this position, especially during

transition into and out of the ‘Service Position’. Use tool

numberT2203to maintain contactbetweenthe connector

blocksifrequired when thetableisinthe‘Service Position’.

Whenreturningthetableoutofthe‘ServicePosition’ensure

the eight M10 screws are tightened to the correct torque

and that the covers are replaced.

Continued use of the table batteries when

‘criticallylow’candamage thebatteries. Charge

batteries regularly to maintain peak

performance. Do not remove the table from

charge until both charging LED’s are ‘green’to

avoid false battery level indication on the

handset.

2.5.5 Duty cycle

Thissymbolis usedtoindicatethetable’sdutycycle

which, in the worst case, is ‘60s : 600s’, the ratio of the

operating time to the sum of the operating time and the

ensuing interval (see note below). Each motor drive has

its own duty cycle and this is dependent on loading and

table position as detailed below.

Trendelenburg 1 : 4 (60s : 240s) at a maximum torque of

417Nm (e.g. 135kg load offset 31cm from the

fulcrum, or a 300kg load offset 14cm from the

fulcrum. Where this load is the patient and

accessoriesweightandtheoffsetishowfartheloads

centre of gravity is, from the centre of the column).

Traverse 1 : 4 (60s : 240s) when the table is

horizontal and at the maximum load of 300kg, or at

17.5°with apatientweight of 225kg,orat 35°witha

patient weight of 150kg.

Break 1 : 10 (60s : 600s) at maximum patient

weight of 300kg.

Height 1 : 4 (60s : 240s) at maximum patient

weight of 300kg (not offset).

Tilt 1 : 4 (60s : 240s) at maximum patient

weight of 300kg.

Note:Theduty cyclesaboveare allforthe worstcase(i.e.

maximum loads). For reduced loading the above duty

cycles can be increased.

2.7 Use in conjunction with other

equipment

2.7.1 Electrosurgical equipment (h.f.)

TheT20-aoperation tablehasbeen designedtominimise

the possibility of accidental electrosurgery burns and can

be used in conjunction with electrosurgical equipment.

However, contact with any metal surfaces (e.g. table side

bars, or other equipment etc.) can cause burns during

electrosurgery and must be avoided.

2.7.2 Defibrillation equipment

With the mains cord attached the equipment has

defibrillator proof applied parts with type BF protection

against electric shock.

2.7.3 Other

When the T20-a is used in conjunction with other infrared

controlled devices, their controllers should be checked to

ensurethatno interferencebetweenthemandtheT20-ais

possible, prior to surgical intervention. Also see the

‘Instructions for Use’.

2.8 Standards compliance

The table has been designed and built to comply with the

followinginternational standards:
