J1 J2 J3 & J5 OPERATION TABLES Part 3

DO:

♦Keep the instruction manual close-to-hand.

♦Read the instructions carefully before using

the table.

♦Check that the leg section is secure, and put

the table base in the brake position before

use.

♦Lower the table top fully before washing the

table.

♦Readandfollowtheinstructionsforcleaning,

and for the care of the mattresses and pads.

♦Use the correct mattress and accessories.

♦Service the table and accessories regularly.

♦Remove table accessories and their clamps,

in particular rotary clamps from side bars,

when they are not in use.

3. SAFETY NOTES

Attention to the following points will prolong the life and efficiency of your operating table and

will help to avoid the risk of accidents, or damage:

DO NOT:

♦Lift the table by its top.

♦Push the table over rough surfaces, use a

trolley.

♦Drop the table (or individual sections) when

transporting it.

♦Put heavy weights on the table sections.

♦Put sharp objects on, or against mattresses,

pads, or the radiographic table top.

♦Drop heavy objects onto the radiographic

top.

♦Spill oil, ether, or other chemical fluids onto

the mattress or the pads.

♦Pull the table by the head or leg section,

always push it.

♦Exceed maximum table loading

WARNINGS

The J Series of Operation Table have been designed to minimise the possibility of accidental

electrosurgery burns. Contact with any metal surfaces (e.g. table side bars, or other equipment

etc.) can cause burns during electrosurgery and must be avoided.

The J Series of Operation Table have been designed for patients weighing up to 135kg with their

centre of gravity (normally the perineum) over the base. However patient positioning and

additional loads can compromise table stability. Ensure that loading does not compromise table

stability.

With the table in (or during transition into) the castor position, the centre of gravity of the

patient (normally the perineum) should lie over the centre of the column. Whenever this is not

practical the overhanging weight of the patient and table should be adequately supported (e.g.

by at least two able people). Take extreme care when moving a table with a patient on and

ensure that the table is at minimum height

The patient’s weight should be supported whenever the sections are adjusted or removed from

the table during re-positioning.

The head and leg sections are designed to support and position the appropriate part of the

patient’s weight only. Damage leading to failure of the section may be caused if excessive weight

is applied.

Themaximum loading weightof 10kg mustnot be exceededfor the Detachableophthalmic head

flap and the Non-Detachable head flap accessories, as this may cause damage to the accessory

and could result in injury to the patient.

It is necessary to check at regular intervals for wear, corrosion, material fatigue and ageing on

allaccessories whichsupport all orpart of thebody of thepatient using asingle gas-spring. Such

accessories are the detachable ophthalmic head flap and the divided leg section.

4. MAINTENANCE

GENERAL

4.1 The information provided in this Service

Manual falls into four categories:

♦ Cleaning, Disinfection, Care and Storage.

♦ Periodiclubrication,checksandadjustments

♦ Fault diagnosis and remedies

♦ Removal and installation of components

CLEANING, DISINFECTION, CARE AND

STORAGE

4.2 For Cleaning, Disinfection, Care and

Storage instructions refer to Section 8 of the

InstructionsforUse(PublicationT-IM22,alsosee

section 1.3).

PERIODIC LUBRICATION, CHECKS

AND ADJUSTMENTS

Base Components (Fig. 2)

4.3 Inorderto carry outmaintenanceprocedures

to the table base, it is necessary to tilt the table on

its side and expose the underside of the base.

Proceed as follows:

i Removethelegsectioninthenormalmanner.

ForJ3 tableremovealso theperineal section

and traverse the table top (see Instruction

Manual, Publication No. T-IM22).

ii Raise the table top to its maximum height.

iii Placeananaesthetist’sstool,orsimilarstrong

support, alongside the table.

iv Placethebrakepedalinthe‘castor’position.

v Stand on the same side of the table as the

support but with the pump lever on the

opposite side. Push the table away about

30 cmandthenpullitback.This ensuresthat

all the castors are pointing away from the

operator.Twopeople on the same side of the

tableasthesupport(oneateachend)cannow

each place a foot against the base and lever

the table over gently, lowering it onto the

support.

Castors and wheels (Fig. 2)

4.4. Clean each castor and wheel free of debris,

then lubricate the castor and wheel ball races with

a light machine oil (or WD40 aerosol lubricant).

Part 4

Brakes and brake mechanism (Fig. 2)

4.5. Check the action of the brake mechanism

and also check for wear on the brake pads, broken

brake pinion or quadrant teeth and play in the

quadrant taper pins. Check stop screws for wear.

To replace quadrant see section 4.39; to replace

quadrant pinion, see section 4.40.

4.6 Fit new brake pads where necessary,

referring to section 4.38.

Hydraulic Cylinder (Fig. 1)

4.7 Raise the table top to its maximum height,

then depress the height adjustment (hydraulic

pump) pedal fully and check for smoothness and

rate of descent.

Fig. 1 Ram key adjustment

4.8 Raise the table top to its maximum height

again and release the ram cover securing screws

at the top. Lower the 3-section telescopic cover

(1) to expose the ram (2) and ram key (3).

4.9 Remove the ram key, clean out keyway and

refit key.

4.10 Examineramsurfaceforrustand, if present,

cleanoff with fine emery cloth. Lubricate exposed

surface of ram. Seal the top of the cylinder with

cloth wound round the ram to prevent damage if

using emery cloth.

4.11 Before refitting ram cover, check that table

will raise and lower smoothly. If this is not the

case, the ram key is probably secured too tightly.

Release the key attachment bolts (4) slightly to

remove excessive friction, then retighten.
