dium Hypochlorite in dilutions ranging between 1 part bleach to 100 parts water, and 2 parts bleach to 100
parts water are not considered mild detergents. These products are corrosive in nature and may cause dam-
age to your stretcher if used improperly. If these types of products are used to clean Stryker patient handling
equipment, measures must be taken to insure the stretchers are rinsed with clean water and thoroughly dried
following cleaning. Failure to properly rinse and dry the stretchers will leave a corrosive residue on the surface
of the stretcher, possibly causing premature corrosion of critical components. Failure to follow the above
directions when using these types of cleaners may void this product’s warranty.
CAUTION
Do not steam clean or hose off the Thermaltek Series Warming Stretcher. Do not immerse any part of the
stretcher. Some of the internal parts of the stretcher are electric and may be damaged by exposure to water.

SIDERAIL LATCH ADJUSTMENT
Required Tools:
1/8 Hex Allen Wrench
WARNING
The siderail latch adjustment is pre–set at the factory, and there should not normally be a need for readjust-
ment. If adjustment must be done it is important to follow the procedure below. If it is not done properly, injury
to the patient or user could occur.
Adjustment Procedure:
1. Using a 1/8 hex Allen wrench, adjust the hex Allen screw located on the latch assembly opposite the latch.
Turning the Allen screw clockwise will DECREASEthe amount of ”play”in the latching mechanism. Turn-
ing counterclockwise will INCREASE the amount.
NOTE
The amount of ”play”in the siderail, when in full up engaged position, should be approximately 1/8 to 3/16
inches.
CAUTION
Too much ”play”when the siderail is in the full up engaged position will give the siderail the appearance of
being unstable and could also cause premature wearing of the latch system.
Too little ”play”will obstruct the latch and keep it from engaging completely in the full up position, which may
cause damage to the latch and/or injury to the patient or user.
