IMPORTANT: IT IS IMPORTANT THAT THE ENTIRE INSTALLATION INSTRUCTIONS BE READ THOROUGHLY
BEFORE PROCEEDING WITH THE INSTALLATION.
1. INTRODUCTION
Thank you for choosing a Link Mortuary Equipment DD2000 Double Deck system. We want to help you to get the best
results from the deck and to operate it safely. This manual contains information to introduce you to the Link Mortuary
Equipment DD2000 and to assist you with its operation. The manual is intended solely for use with this product.
All information in this manual is based on the latest information available at the time of printing. Link Manufacturing
reserves the right to change its products or manuals at any time without notice. Contact Link Mortuary Equipment at (800)
248-3057 for information on recent changes to products.
Damaged components should be returned to Link with a pre-arranged Returned Materials Authorization (RMA) number
through the Customer Service Department. The damaged component may then be replaced if in compliance with warranty
conditions.
2. SAFETY SYMBOLS, TORQUE SYMBOL, and NOTES
3. SAFE WORKING PRACTICES
The operation of the DD2000 Double Deck transport system involves moving parts.
During the course of travel pinch points may exist between components.
Keep hands and fingers clear of moving components during operation.
Practice safe lifting procedures.
The deck weldments are heavy, and can cause injury if lifted improperly or dropped. Consider size,
shape, and weight of objects being moved.
Obtain help or the assistance of a crane when lifting heavy assemblies. Make certain the path of travel is
clear.
4. OPERATION GUIDELINES
4.1 In order for this deck to operate properly, it must operate in the parameters specified by Link.
4.2 No alterations of any Link deck component is permitted without proper authorization from qualified Link personnel.

5. OPERATION
Make certain the vehicle is in park and the parking brake is engaged before loading / unloading the ve-
hicle.
Vehicle movement during loading / unloading could cause operator injury or death.
The capacity of the top deck is 600 pounds maximum, evenly distributed.
Loading beyond the capacity may result in equipment damage or failure that may result in injury or
death.
5.1 Top Deck Controls & Operation
Immediately inside the rear doors against one of the side walls is the top deck control box.
There are three items on the control box:
• System Lock On/Off switch (with key)
• Top Deck Raise / Lower Rocker Switch
• Circuit Breaker Reset Button
Operation:
• To operate the deck, turn the power key to the “ON” position.
• Push the rocker switch to “RAISE” to raise the deck.
• To lower the top deck, push the rocker switch to “LOWER”.
• Turn the power switch to the “OFF” position and remove the key when you are finished operating the deck.
The System Lock On/Off key switch should be turned to off and the key removed if the unit is left unat-
tended to prevent unauthorized use.
5.2 Loading / Unloading Procedure
1. With the vehicle in park and the parking brake secured, open the rear door of the vehicle.
2. Fold down the rear ramp.
3. If the top deck is to be used and is in the up position, lower the top deck by following the procedures outlined in
Step 5.1 of this manual.
Make certain that the load is properly secured by properly tightening the bier pin(s).
Caskets placed on both the top and bottom deck are prevented from lat-
eral movement by the friction of the front bumpers combined with the
clamping force of the bier pin.
4. Slide the items to be transported on to the top deck, taking care to evenly distribute
the load as best as possible. Secure items with the bier pins (if caskets) or by plac-
ing the legs in the cups (hospital cots).
5. Raise the top deck and place items to be transported on the bottom deck, taking care
to properly secure the load.
6. Turn the System Lock On/Off Switch to “OFF” and remove the key.
7. Raise the rear ramp.
8. Close the rear doors.
9. Reverse the procedure for unloading.
6. MAINTENANCE
Park the vehicle in a level, flat area, and apply the parking brake before performing any maintenance.
Turn the “System Lock” key switch to the “Off” position and remove the key before performing any maintenance.
Perform maintenance work from outside the deck, whenever possible.
The DD2000 is designed to last for many years without any major maintenance. Periodically, check the following items:
Each Time the System is Used:
• Listen for unusual noises and watch to ensure proper movement of the system. If there is a problem, correct it be-
fore continuing to use the system.

6. MAINTENANCE (CONT’)
Annually:
• Check tightness of all fasteners. (Refer to Torque Table below)
• Visually inspect for cracks or damage at all pivots on the framework and torsion bar and replace pivot bushings or
pins if necessary.
• Check for cracks in the framework and decks and repair or replace if necessary.
• Verify that the electrical control system functions as intended.
Perform these checks with the Upper Deck lowered.
7. SERVICE
Procedure for replacing an inoperative actuator:
1. If the deck is lowered, or can be lowered, skip to step 6. If the deck is raised and stuck, complete steps 2 through
5 before proceeding.
Park the vehicle in a level, flat area, and apply the parking brake before performing any maintenance.
Turn the “System Lock” key switch to the “Off” position and remove the key before performing any
maintenance.
Perform maintenance work from outside the deck, whenever possible.
1.
2. If the deck is loaded, remove the load if possible.
3. Place jack stands or blocks under the top deck to support it in the raised position while preparing it to be lowered.
4. If necessary, use a jack or forklift to lift the top deck slightly, to free the actuators and actuator pivot bolts.
5. Disconnect the inoperative actuator(s) from the control wiring harness. Unfasten the inoperative actuator(s) from
the torsion arm weldment and the actuator mount.
The top deck will be free to move if both actuators are disconnected from the torsion arm, and Will Fall
if Unsupported.
Do NOT force out the actuator pivot bolts. If the pivot bolts are difficult to remove they may still be sup-
porting the top deck. When the load is removed from the actuators the pivot bolts will be easy to re-
move.
6. Check that no persons or objects are on the lower deck, or in the cargo area, then remove the supports and care-
fully lower the top deck. If one actuator is still functioning and connected, lower the top deck using the normal op-
erating procedure. NOTE: One actuator is sufficient to safely lower the top deck, but does not have the capacity to
raise the top deck while loaded.
• If both actuators were non-functioning and disconnected, use a jack or forklift to carefully lower the top deck
onto wood blocks placed on top of the lower deck. The top deck should be held 1-2 in. above the lower deck.
7. Extend the replacement actuator(s) with an auxiliary 12 volt source, and fit the new actuator(s) to the actuator
mount and torsion arm.
8. Connect the new actuator(s) to the control wiring harness. Ensure that all persons are clear of the cargo area, and
test the operation of the deck through several cycles.
Procedure for clearing blockages in the DD-2000:
1. If the deck is loaded, remove the loads, and lower the top deck, if possible.
2. If the top deck is in the raised position, place jack stands under the top deck for support.
3. Remove the blockage, working from above the upper deck or from the side door, if possible.
Park the vehicle in a level, flat area, and apply the parking brake before performing any maintenance.
Turn the “System Lock” key switch to the “Off” position and remove the key before performing any
maintenance.
Perform maintenance work from outside the deck, whenever possible.
4. Inspect the decks, frame, and mechanism for damage.
5. Ensure that all persons are clear of the cargo area, and remove the jack stands.
6. Test the operation of the deck through several cycles.
