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.
• 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 Sagittal 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. • Reuse of single use blades can cause blade breakage and possible injury to the patient and/or user.
CAUTIONS: • 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.
• 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
Features and Functions • Battery Latch - Depress the latch to release the battery pack from the handpiece. • Battery Pack - Contains a rechargeable battery that provides power to the handpiece. • Blade Lock Button - The button allows the insertion and release of the blade. • Blade Retainer- The retainer holds the blade. • Sagittal Head - The sagittal head may be indexed in 45° increments and can turn in a complete 360° rotation to achieve the desired cutting angle. • Trigger Switch - The trigger is pressure sensitive for variable speed operation. When rotated, the trigger switch allows the cutting tool to operate in STD (standard), SAFE and FAST mode.
Blade Lock Button Blade Retainer Sagittal Head
Battery Latch Trigger Switch
Battery Pack
Symbol Definitions The STD (standard) position allows the handpiece to operate at high torque and standard speed when the trigger is depressed.
The SAFE position locks the trigger and prevents inadvertent operation of the handpiece; the handpiece cannot be operated.
4
The FAST position allows the handpiece to operate at high torque and high speed when the trigger is depressed.
Instructions Blade Installation
Sagittal Head Positioning 1. Pull the sagittal head forward and away from the handpiece body; then rotate it to the desired cutting angle (see figure 2).
WARNING: Always place the trigger switch in the SAFE position before attaching or removing any accessory to prevent inadvertent running of the handpiece.
NOTE: The sagittal head has eight possible cutting angle positions (45° increments).
1. Rotate the trigger switch clockwise to the SAFE position.
CAUTION: Before use, the sagittal head must be firmly locked against the handpiece body to prevent damage to the instrument. Ensure NO gap exists between the sagittal head and the handpiece body.
2. Depress the blade lock button and insert the blade until the FULL INSERT line disappears in the blade retainer indicating the blade is positioned properly (see figure 1).
2. Once positioned, gently turn the sagittal head to ensure that it has snapped into place against the handpiece body and is locked into position (see figure 2).
3. Release the blade lock button. Gently tug the blade to ensure it is secure.

2. Test the operation of the handpiece by rotating the trigger switch to either the STD or FAST position and squeezing the trigger.
Battery Pack Installation NOTES:
3. Set the trigger switch to the SAFE position until you are ready to use the handpiece.
• The Sagittal Saw is designed to accept REF 4115, REF 4116, or REF 4126 batteries. These batteries may be charged in the System 4 or 5 Battery Charger configured with Charger Module REF 4110-415, REF 4110-416, or REF 4110-426 respectively. The REF 4115 battery may also be charged in the System 2000 Charger with Battery Adaptor (REF 4110-115). • Refer to the instructions supplied with the battery charger and/or battery for charging details and specifications.
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.
Battery Pack Removal Depress the battery latch and pull the battery pack out.
Blade Removal Depress the blade lock button and remove the blade. Battery Latch
