Scoop EXL Stretcher Series
5.5 Inspecting the Stretcher
Have your service’s equipment maintenance personnel
inspect the stretcher regularly. Follow the checklist
below and work the stretcher through all its functions
as described in this manual.
5.6 Lubricating the Stretcher
The stretcher’s head-end and foot-end couplings are
lubricated during assembly but may require additional
lubrication with use.
Choose one of the following lubrication methods. Apply
lubricant(s) to the points indicated below:
METHOD A
(WHITE LITHIUM GREASE)
1. Apply a small amount of white lithium grease to
the sliding surfaces of the end couplings.
2. Wipe off excess lubricant.
METHOD B
(DRY-COATING TEFLON
™
LUBRICANT)
1. Spray a very small amount of general purpose,
dry coating Teflon
™
lubricant onto the sliding
surfaces of the end couplings. Follow the lubricant
manufacturer’s instructions.
2. Wipe off excess lubricant.
If inspection indicates damage or excessive wear, take
the stretcher out of service until repairs are made (see
Parts and Service
, page 19).
If inspection indicates damage or excessive wear to
restraint(s), take restraint(s) out of service and destroy
to prevent accidental use. For replacement restraints,
contact your Ferno distributor or Ferno Customer
Relations (page 21).
Keep maintenance records.

5.7 Checking and Securing Pins in
the Couplings
Follow the instructions below to check that the pins in
the Twin Safety Lock

If a pin has loosened, follow the instructions on page
16 to tighten it. If a pin is missing, remove the stretcher
from service until the pin has been replaced (see
Parts
and Service
, page 19).
CHECKING THE PINS
There are four threaded pins in the couplings: one pin
in each half of each coupling (Figure 11). Loctite
®
270
threadlocker is applied to the pins during assembly of

INSPECTION CHECKLIST
Are all components present?
Is the stretcher free of excessive wear?
Do all moving parts (couplings, levers, hinges,
and sliding frame) operate smoothly and
properly?
Are the coupling pins securely in place? (See
subsection 5.7, pages 15 and 16.)
Does the foot section lock properly into each
position?
Are all 8 speed-clip pins securely in place?
(For stretchers with pins.)
Do the head- and foot-end couplings require
lubrication?
