TSL Extender - Scoop EXL
Lubrication
Clean and disinfect the stretcher before lubricating it. Use
appropriate lubricants.
The couplings for the head and feet sections are lubricated
during assembly of the stretcher, but may require additional
lubrication, if necessary, during normal use.
It is possible to choose one of the following methods (A or
B) of lubrication:
A. WHITE LITHIUM GREASE: apply a small amount of
white lithium grease on the sliding surfaces of the couplings.
Eliminate any excess.
B. TEFLON LUBRICANT SPRAY FOR GENERAL
USE: spray a small amount of lubricant on the sliding
surfaces of the couplings. Eliminate any excess.
Important
If you lubricate components that do not need to be
lubricated, this can allow dirt and foreign particles
to accumulate, causing damage to the components.
Lubricate only the components indicated.
6.6 Monitoring and locking of the
coupling pins
There are two threaded pins in each Twin Safety Lock (TSL)
system.

During assembly of the stretcher, thread-lockers are applied
to these pins. If a pin has come loose, it is possible to apply
additional thread-locker, as reported in the subsection
"Reinstalling the pins".
The procedures described should be performed solely and
exclusively by qualified technical staff. Contact Ferno
Washington Italia's Technical Support Service.
INSPECTION OF THE PINS
To check if the pin is loose, proceed as follows:
1. Use 12 mm max. needle-nose pliers
2. Cover the nose pliers with duct tape to prevent damage
to the surface of the pins.
3. Try to unscrew the first pin. If the pin holds and you
cannot unscrew it without further effort, the pin is
locked into place. If the pin unscrews easily, follow the
instructions in the subsection "Reinstalling the pins".
4. Check the remaining three pins and reinstall only the
pins that are not locked properly.
REINSTALLING THE PINS
In the event that one of the pins is loose, proceed as follows
to lock it properly:
1. Unscrew the loose pin and remove it from the Twin
Safety Lock system.
2. Completely remove all traces of thread-locker in the
pin's thread and seat.
3. Dry the cleaned surfaces of the thread of the pin and
seat.
4. Apply Loctite 270 on the dried surfaces of the two
threads until they are completely covered by the thread
locker.
5. Insert the pin into the coupling seat and use the pliers
Pin
to tighten it.
6. Remove any excess thread-locker.
7. Let the thread-locker dry for a few hours before
resuming use of the stretcher.
If a pin is missing, put the stretcher out of service immediately
and contact Ferno Washington Italia's Technical Assistance
Service.
