Listing of Warnings and Cautions Operator Manual 075995
The following is a listing of the safety precautions which must be observed when operating and servicing this equipment.
WARNINGS indicate the potential for danger to personnel, and CAUTIONS indicate the potential for damage to
equipment. These precautions are repeated (in whole or in part), where applicable, throughout the manual.
WARNING–LACERATION HAZARD:
When cutting bands always use a tool specifically designed for that purpose. This will help to avoid personal
injuries frequently incurred when bands are cut and tension released.
WARNINGS – PERSONAL INJURY:
Do not sit or stand on end - tipping may occur.
Be sure the I.V. rod is inserted completely into socket up to the arrow before applying load.
To reduce the risk of electric shock, do not remove the cover. Unit is to be service by qualified personnel only.
See Section 3 for the Warnings below:
WARNINGS – CAUTIONS AND PROPER OPERATION:
The stretchers have a warning label located at the head end stating: Maximum patient weight 226 Kilograms (500
Lbs.)
Patient entry, egress and transfer should always be done with the brakes locked.
The brakes should always be locked and patient side rails up when patient is not in transport.
The patient pendant has a warning label on it stating: Clip pendant to rail when not in use - Keep cord clear of
moving parts.
It is important to remember that all electric stretchers are equipped with a built in battery backup system but: It
is recommended that the unit remain plugged in wall receptacle during normal use. The battery back backup
is recommended for transport and emergency only.
The Fowler backrest quick drop handle is intended to be used during emergency situations only.
Be sure rail is locked before leaving patient.
The lock out knobs deactivate both the patient pendant and the control panel.
The stretcher has a warning label on the tube of the leg section stating: Severe damage could occur to stretcher.
Before raising the foot section, the heel stirrup axial adjustment must be straight.
The stretcher has a warning label on the end of the foot section stating: Do not sit on foot section. Tipping may
occur.
The stretcher has a warning label on the foot rest stating: Do not stand on foot rest.
To turn electric controls on, plug into wall receptacle. To turn off, remove plug from wall receptacle. The electric
powered stretchers do not have a separate on/off switch.
The stretcher has a warning label located on the control box cover stating: To reduce the risk of electrical shock
do not remove the cover. Service by qualified personnel only.
Always disconnect the power source whenever servicing any electric powered stretcher.

075995 Operator Manual Listing of Warnings and Cautions
Do not use a sharp instrument to remove fuse, as it may scratch the circuit board.
The batteries are wired in series, failure to install or rewire the same way may cause the batteries to explode.
The stretcher has a warning label on the tube of the leg section stating: Do not transport patient in the chair
configuration (tipping may occur).
Floors must be smooth and level to maintain optimum fifth wheel steering. Fifth wheel steering functions can be
influenced by floor irregularities (bumps or dips) greater than 1/2 inch (13 mm) across the span of the stretcher.

Unpacking Instructions Operator Manual 075995
UNPACKING INSTRUCTIONS 2
IMPORTANT: Report any shipping damage immediately! Inform shipper of
any damages – leave carton intact. Leave the stretcher in the receiving area
until inspection is complete.
Your Converge stretcher has been carefully packaged at our manufacturing
plant to ensure safe shipment to you medical facility. There are several
procedures you must follow to put your new stretcher into service. These
procedures only take a few minutes to complete and are required to ensure
proper operation of the stretcher.
Step 1 – Cut the two metal bands around the shipping carton.
Step 2 – Remove the top half of the carton and cut one side of the bottom half.
Step 3 – Remove the stretcher from the carton. Cut the metal bands from
around the stretcher.
Step 4 – Check to see if all features of the stretcher work properly.
NOTE: You must first plug the unit into a wall socket to check any
electric features, as the battery has not been charged (see Step 6).
If all features work properly, go to step 5. If any of the features of the
stretcher do not work properly, call STERIS for service.
Step 5 – Clean the stretcher using a mild detergent to remove any dirt
accumulated during shipment.
Step 6 – Plug the unit into a wall socket to charge for approximately 8 hours
to charge the battery backup.
Step 7 – Place the unit into service.
WARNING – LACERATION
HAZARD: When cutting
bandsalwaysuseatoolspe-
cifically designed for that
purpose. This will help to
avoid personal injuries fre-
quently incurred when

Step1: Check all motor and column plug connections at the controller box.
Step 2: If a column does not move: Check the the connection at the column.
Step 3: Plug a connector from the faulty component into a different socket:
If the component does not run:
– Replace that component.
If the component does run:
– Test pendant by plugging a functioning component into the non-
functioning socket on the controller. If this component does not run,
replace the pendant. If replacing the pendant does not fix the problem,
then the controller must be replaced.
Step 1: Plug unit into a mains supply wall receptacle, observe the pilot light
on the controller:
If the pilot light is off:
- Replace the controller
If the pilot light is on:
1. Check the nurse control plug connection at the controller.
2. Check the pendant control plug connection at the controller.
Step 1: Plug unit into a wall receptacle overnight. If the batteries do not hold
a charge, replace the batteries.
