User/Patient Safety* WARNINGS: • Read and understand the information in this manual. Familiarization with the Stryker System 5 Battery Powered Instruments prior to use is important. • Prior to each use, operate system components and inspect for damage. DO NOT use if damage is apparent. Take special precaution regarding electromagnetic compatibility (EMC) when using medical electrical equipment like the System 5 handpiece. Install and place the handpiece into service according to the EMC information in this manual. Portable and mobile RF communications equipment, such as wireless phones, can affect the function of the handpiece. • 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. • Prior to each use, system components should be operated and inspected for any loose components or damage. DO NOT use if these conditions exist. Loose components could fall off the handpiece into the wound site causing potential patient injury. • Clean and sterilize instruments before first and every use. • This equipment is not suitable for use in the presence of flammable anesthetic mixture with air or with oxygen or nitrous oxide. • Avoid unintentional operation of the handpiece. A handpiece that contains a battery should always be placed in the SAFE mode while it is either sitting idle or an accessory is being attached or removed. Remove the battery pack from the handpiece when the instrument is not in use.
• DO NOT pry or use excessive force on the blade as the blade may bend and/or break causing potential patient injury. • Use only Stryker approved accessories. Only Stryker saw blades can be used with the Recip/Sternum Saw. A list of accessories is available from your Stryker Instruments sales representative. • DO NOT service handpieces or battery packs. These products contain no parts that the user can service. • If you are using a Stryker Reciprocating Double Sided Blade (REF 277-96-275) or a Reciprocating Heavy Duty Blade (REF 277-96-325), be alert to blade whip when the handpiece is operated below the maximum speed. Blade whip increases the chance of blade fracture and user/patient injury. • DO NOT operate the handpiece until the blade is in contact with bone or tissue. Operating the handpiece before the blade is in contact with bone or tissue may cause the blade to break or eject from the handpiece and endanger persons nearby. • Reuse of single use blades can cause blade breakage and possible injury to the patient and/or user.
CAUTIONS: • DO NOT stall the handpiece to prevent damaging the electric motor and/or battery pack. If the handpiece jams, release the trigger immediately. Remove any obstructions before continuing the procedure. • DO NOT immerse the handpiece or battery pack. Water may enter the casing and damage the electrical components.
*For further information, contact your Stryker Instruments sales representative or Customer Service at 1-800253-3210. Outside the USA, contact your nearest Stryker subsidiary. 3

Instructions Blade Installation
Sternum Blade Guard Installation
WARNING:
NOTE: When the sternum blade guard is used, it can be installed in the orientation shown or rotated 180° (see figure 2). The blade teeth must point away from the sternum blade guard.
Always place the safety switch in the SAFE position before attaching or removing any accessory to prevent inadvertent running of the handpiece. 1. Rotate the safety switch clockwise to the SAFE position. 2. Rotate the spring-loaded blade collar clockwise aligning the slots. Insert the blade (see figure 1).
NOTE: The blade teeth may be directed in any of four positions. However, if using the sternum blade guard, the teeth must point away from the sternum blade guard.
Figure 2 Guard Installation
3. Release the blade collar. Ensure the blade collar springs back to its original position indicating the blade is properly seated.
1. Slide the guard actuating button and position the sternum blade guard over the blade so that the blade’s teeth are pointing away from the guard. Release the guard actuating button to secure the sternum blade guard.
4. Gently tug the blade back and forth to ensure it is secure.
2. Gently tug the sternum blade guard to ensure it is secure. 3. Visually inspect the blade and sternum blade guard to ensure the blade neither retracts nor extends from the sternum blade guard.
Figure 1 Blade Insertion 5
Instructions (cont’d) WARNINGS: • If the blade retracts or extends from the end of the sternum blade guard, the blade may cause tissue damage. • Do not grasp the handpiece near the guard actuating button or handle the handpiece in a way that may displace the guard actuating button during use. Displacing the guard actuating button causes the sternum blade guard to disengage and may cause loss of tactile control and patient injury.

2. Test the operation of the handpiece by setting the safety switch to the RUN position and squeezing the trigger.
NOTES: • The Recip/Sternum Saw is designed to accept REF 4112, REF 4212, REF 4215, REF 4222 or REF 4226 batteries (or kit). These batteries may be charged in the System 4 Battery Charger configured with Charger Module REF 4110-412, REF 4110-422, or REF 4110-426 respectively. The REF 4112 battery may also be charged in the System 2000 Charger with Battery Adaptor (REF 4110-112). • Refer to the instructions supplied with the battery charger and/or battery for charging details and specifications.
3. Set the safety switch to the SAFE position until you are ready to use the handpiece.
Saw Operation NOTE: The handpiece has a variable speed motor that is controlled by slight pressure variations on the trigger.
CAUTION:
1. Slide a fully charged battery pack firmly into the handpiece until the battery latch snaps, indicating the pack is secure (see figure 3).
When operating the saw, let the blade do the cutting. Applying too much pressure will bend the blade and reduce the cutting quality.
