SET−UP PROCEDURES
It is important that the Model 660Z Stretcher is working properly before it is put into service. The following
list will help ensure that each part of the unit is checked.
SPlug the power cord into a properly grounded, hospital grade wall receptacle. The 12 volt batteries that
provide power to the drive wheel and back−up power to the unit functions will charge whenever the power
cord is plugged into the wall socket. The batteries require approximately 6 hours of charging time before
the stretcher is put into service.
WARNING
The Model 660Z Stretcher is equipped with a hospital grade plug for protection against shock hazard. It must
be plugged directly into a properly grounded three−prong receptacle. Grounding reliability can be achieved
only when a hospital grade receptacle is used.
SDepress the pedal at either end of the stretcher fully to set the four wheel brakes and verify all four casters
are locked.
SEnsure the siderails raise and lower smoothly and lock securely in the full up position.
SRun through the operation of the drive wheel to ensure it is operating properly.

Quaternary Germicidal Disinfectants, used as directed, and/or Chlorine Bleach products, typically 5.25% So-
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 damage 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 cor-
rosive residue on the surface of the stretcher, possibly causing premature corrosion of critical components.
NOTE
Failure to follow the above directions when using these types of cleaners may void this product’s warranty.
REMOVAL OF IODINE COMPOUNDS
This solution may be used to remove iodine stains from mattress cover surfaces.
1. Use a solution of 1−2 tablespoons Sodium Thiosulfate in a pint of warm water to clean the stained area.
Clean as soon as possible after staining occurs. If stains are not immediately removed, allow solution to
soak or stand on the surface.
2. Rinse surfaces which have been exposed to the solution in clear water before returning bed to service.
