Safety Information
Always prioritize safety when operating power tools. Failure to follow safety instructions can result in serious injury or property damage.
- Eye Protection: Always wear appropriate eye protection, such as safety goggles, when operating the saw.
- Hand Protection: Wear heavy-duty gloves to protect your hands from sharp blades and debris.
- Secure Workpiece: Ensure the material you are cutting is securely clamped or held to prevent movement during operation.
- Proper Grip: Maintain a firm grip on the saw with both hands during operation.
- Clear Work Area: Keep your work area clean and well-lit. Remove any obstacles that could cause tripping or entanglement.
- Avoid Kickback: Be aware of potential kickback, especially when cutting through dense materials or if the blade binds.
- Blade Selection: Use the correct blade type for the material being cut (e.g., wood, metal).
- Battery Safety: Only use RYOBI ONE+ 18V Lithium-Ion batteries. Do not expose batteries to water or extreme temperatures.
- Child Safety: The saw features a safety switch to prevent accidental activation. Always engage the safety switch when the tool is not in use, especially around children.

Setup
Battery Installation:
This tool is sold as a bare tool and requires a RYOBI ONE+ 18V Lithium-Ion battery (sold separately).
- Ensure the saw's lock-off switch is engaged (in the locked position).
- Align the battery with the battery port on the bottom of the saw.
- Slide the battery into the port until it clicks securely into place.

- Ensure the saw is disconnected from its power source (battery removed) before changing blades.
- Lift the blade clamp lever located near the front of the saw.
- Insert the shank of the reciprocating saw blade fully into the blade clamp.
- Release the blade clamp lever. The blade should be securely locked in place. Gently pull on the blade to confirm it is seated properly.
- To remove a blade, lift the blade clamp lever and pull the blade straight out.
Operating Instructions
General Operation:

- Ensure a fully charged battery is installed and the correct blade is attached.
- Grip the saw firmly with both hands.
- To start the saw, push the lock-off switch to the unlocked position, then depress the trigger. The saw will begin to operate.
- To stop the saw, release the trigger. Always engage the lock-off switch when finished cutting or when setting the tool down.
Cutting Techniques:
- Starting a Cut: Place the shoe firmly against the workpiece. Start the saw before the blade contacts the material.
- Cutting Wood: Use a wood-cutting blade. Apply steady, even pressure. Allow the saw to do the work; do not force it.
- Cutting Metal: Use a metal-cutting blade. For thicker metals, consider using cutting fluid to prolong blade life and improve cutting efficiency. Maintain a moderate speed.
- Plunge Cutting: For plunge cuts (starting a cut in the middle of a workpiece), ensure the blade is sharp and the shoe is firmly pivoted against the material. Slowly angle the saw until the blade penetrates the surface.
- Demolition: This saw is ideal for demolition tasks. Be aware of hidden wires or pipes within walls or structures.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your reciprocating saw.
- Cleaning: After each use, wipe down the tool with a clean, damp cloth. Remove any sawdust, metal shavings, or debris from the ventilation openings and blade clamp area. Do not use harsh chemicals or abrasive cleaners.
- Blade Care: Inspect blades before and after each use for sharpness and damage. Replace dull or bent blades immediately. Store blades in a dry place to prevent rust.
- Battery Storage: Store batteries in a cool, dry place away from direct sunlight and extreme temperatures. For long-term storage, ensure batteries are partially charged.
- General Inspection: Periodically check all screws and fasteners for tightness. Ensure the shoe moves freely and locks securely.
Troubleshooting
If you encounter issues with your saw, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Saw does not start. | Battery not installed correctly or discharged. Lock-off switch engaged. | Ensure battery is fully seated and charged. Disengage the lock-off switch. |
| Blade not cutting effectively. | Dull or incorrect blade for material. Excessive force applied. | Replace with a sharp, appropriate blade. Reduce cutting pressure. |
| Excessive vibration. | Loose blade. Damaged blade. | Ensure blade is securely clamped. Replace damaged blade. |
| Saw stops during operation. | Overload protection activated. Battery discharged. | Reduce load on the saw. Allow tool to cool. Recharge or replace battery. |
