The Model 300 Series Medical Examination Table is primarily used in examination rooms for general examinations and minor procedures. The table top is adjustable from a full horizontal position to a chair position. Also, when supported with an optional pelvic lift bar, the lithotomy position can be achieved. There are five storage drawers which accommodate supplies used during examinations.

The major serviceable components of the table are the drawer heater plate (optional) (1, Figure 1-1), heater on/off switch (optional) (2), electrical receptacle (3), back lock assembly (4), lift assembly (5), step assembly (6), and two stirrup assemblies (7).

The Model 300 Series Medical Examination Table is available in six different configurations and are distinguished by the following model numbers:

Model 300-001 Non-pelvic tilt, drawers on patient's

right side.

Model 300-002 Non-pelvic tilt, drawers on patient's left

side.

Model 300-003 Pelvic tilt w/ heater, drawers on

patient's right side.

Model 300-004 Pelvic tilt w/ heater, drawers on

patient's left side.

Model 300-005 Perineal cut-out in seat section,

drawers on patient's right side.

Model 300-006 Perineal cut-out in seat section,

drawers on patient's left side.

B. Theory of Operation (See Figures 5-1 for wiring

diagrams / electrical schematics.

Electrical Power:

115 VAC line voltage is supplied thru the power cord to electrical receptacles located on the side of the table. As long as the power cord is plug into a supply outlet 115 VAC power will be present at the receptacles.

1.3 Description Of Model 300 Medical Examination Table.

A. General Description (See Figure 1-1).

Optional Heater Plate: Some units are equipped with the optional heater plate for drawer warming. When the operator turns the (N.O.) Heater On/Off Switch to ON, closing the circuit, power is supplied to the 60 watt heater plate, heating the unit. This provides heat in the top, foot end drawer to warm instruments.

NOTE

For ease of installation it works best to remove the hinge assembly (13, Figure 4-1), lay the head (8) and seat (2) sections in position on a flat surface with the lower or back sides facing upward, and install the hinge cover (11) and top hinge (13). Once this has been completed install the entire upholstered assembly onto the table.

(1) Lay the new head board (8, Figure 4-1) and

seat section (2) in position on a flat surface with the face (upholstery side) down.

The pre-drilled holes on the back of the head (8) and seat section (2) for the top hinge (13) may be hidden by the excess vinyl of the head and seat sections. Cut small incisions over each hole, in the excess vinyl, for insertion of the hinge screws.

(2) Place the hinge cover (11) and the top hinge

(13) in position over the pre-drilled holes on the backs of the head board (8) and seat section (2) and secure with the screws (12 and 14).

CAUTION

Use care when installing the upholstered

top assembly as it weighs approximately 60 lbs. (27.2 kg). Failure to use proper lifting techniques or assistance could result in personal injury.

screws (1) that secure the seat section (2) to the upper wrap cross member (A).

NOTE

Do not tighten the two screws (10) that secure the back support rod assembly (3) to the head board assembly (8) at this time. This will allow the back support rod assembly (3) to self-align itself and prevent binding when the back support rod (3) is inserted thru the back lock assembly (5) and the head board (8) is raised and lowered.

(5) Place the back support rod assembly (3) on the

back of the head board assembly (8) at the location of the pre-drilled holes for the bracket screws (10) and loosely install the screws but do not tighten them yet.

PARTS LIST

6.1 Introduction

The illustrated parts list provides information for identifying and ordering the parts necessary to maintain the unit in peak operating condition. Refer to paragraph 1.5 for parts ordering information.

The parts list also illustrates disassembly and assembly relationships of parts.

6.2 Description of Columns

The

Item

column of the parts list gives a component its own unique number. The same number is given to the component in the parts illustration. This allows a part number of a component to be found if the technician can visually spot the part on the illustration. The technician simply finds the component in question on the illustration and notes the item number of that component. Then, he finds that item number in the parts list. The row corresponding to the item number gives the technician the part number, a description of the component, and quantity of parts per subassembly. Also, if a part number is known, the location of that component can be determined by looking for the item number of the component on the illustration.

The

Part No.

for that component.

column lists the MIDMARK part number

component that is required for the subassembly. The letters “AR” denote “as required” when quantities of a particular component cannot be determined, such as: adhesive.

Bullets { • } in the column show the indenture level of a component. If a component does not have a bullet, it is a main component of that illustration. If a component has a bullet, it is a subcomponent of the next component listed higher in the parts list than itself that does not have a bullet. Likewise, if a component has two bullets, it is a subcomponent of the next component listed higher in the parts list than itself that has only one bullet.

6.3 Torque Specifications and Important Assembly Notes

When specific assembly torque specifications, measurements, or procedures have been identified, by our engineering department, as required to assure proper function of the unit, those torque specifications measurements, and procedures will be noted on the parts illustrations. Adherence to these requirements is essential.
