User/Patient Safety

WARNINGS:

• Prior to each use, operate system components and inspect 

for damage.  DO NOT use if damage is apparent.  Take 
special precautions regarding electromagnetic compatibility 
(EMC) when using medical electrical equipment like the Cast 
Cutter REF 941.  Install and place the Cast Cutter REF 941 
into service according to the EMC information in this manual.  
Portable and mobile RF communications equipment can affect 
the function of the Cast Cutter REF 941.

• Use only Stryker approved accessories.  Other accessories 

may result in increased emissions or decreased immunity of 
the system.  Contact your Stryker sales representative for a 
complete list of accessories.  DO NOT modify any accessory.  
Failure to comply may result in patient and/or operating room 
staff injury.

• This equipment is not suitable for use in the presence of 

flammable anesthetic mixture with air or with oxygen or nitrous 
oxide.

 Use only Stryker Cast Cutter Blades.

 Titanium nitrided blades 

are intended to cut synthetic casting material; and stainless 
steel blades to cut plaster casting material.  Ion nitrided blades 
will cut synthetic or plaster casting material.  See 

Reorder List

 

in this manual for details.

• Prior to use, check blades for wear.  DO NOT use a dull 

blade.  Use of a dull blade could result in a burn injury to 
tissue.

• Make sure blade is properly seated and retaining nut is 

tightened before each use.  An improperly tightened retaining 
nut may come loose, causing blade to fracture, thereby 
endangering patient and user.

• Excessive pressure, such as bending and prying with the 

blade, may cause the blade to fracture.  This could result in 
injury to the patient or user.

• Do not cut casting material using a continuous linear motion.  

Continuous contact of the blade against skin or padding will 
cause a burning sensation to the underlying skin.

• Use extreme caution when cutting synthetic casting materials.  

The Cast Cutter blade may overheat, causing burn to 
underlying tissue.

• DO NOT remove a non-padded cast with the Cast Cutter.  Skin 

may adhere to the casting material which could result in injury 
to the tissue.

• Your Stryker Cast Cutter is double insulated; grounding is not 

required.  The Cast Cutter must be completely dry when it 
is used.  Do not use if any moisture is apparent, which may 
occur after cleaning the instrument.

• Disconnect the Cast Cutter from the electrical supply before 

performing any cleaning or maintenance procedures.

• DO NOT autoclave or immerse this instrument in liquids.  Do 

not flush the internal vacuum line with liquids.  Liquids would 
seriously damage the internal components of the Cast Cutter 
and create an unsafe electrical condition.

• Do not use in the presence of fluids.

• Use only identical replacement parts. 

CAUTION:

 Stryker does not recommend using Stainless Steel 

Blade REF 940-25 for cutting
