2. Important Safety Instructions
Always observe basic safety precautions when using electric tools to reduce the risk of fire, electric shock, and personal injury.
- Work Area Safety: Keep your work area clean and well-lit. Cluttered or dark areas invite accidents. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
- Electrical Safety: Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is grounded.
- Personal Safety: Always wear eye protection. Use safety glasses or goggles. Wear hearing protection for extended periods of operation. Dress properly; do not wear loose clothing or jewelry. Keep hair, clothing, and gloves away from moving parts.
- Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. Disconnect the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools.
- Battery Pack Use and Care: Recharge only with the charger specified by the manufacturer. Do not use a battery pack or tool that is damaged or modified.

4. Setup
4.1 Charging the Battery
The Ryobi HP108L features an internal 8 Volt Lithium Ion battery. To charge the drill:
- Connect the charger to a standard electrical outlet.
- Plug the charger into the charging port on the drill.
- Allow the drill to charge until the charging indicator light on the charger or drill indicates a full charge. Charging time may vary, typically taking several hours.
Note: The drill cannot be operated while charging. Refer to the charger's specific instructions for detailed charging procedures and indicator meanings.
4.2 Installing/Removing Bits
The drill is equipped with a keyless chuck for quick bit changes.
- To install a bit, rotate the chuck counter-clockwise until the jaws are open wide enough to insert the bit.
- Insert the desired drill bit or driving bit into the chuck. Ensure the bit is inserted as far as possible and centered.
- Rotate the chuck clockwise to tighten the jaws securely around the bit. Hand-tighten firmly.
- To remove a bit, rotate the chuck counter-clockwise until the jaws release the bit.
The kit includes a double-sided hex bit (Phillips/slot head) for immediate use.
5. Operating Instructions
5.1 Powering On/Off and Speed Control
The drill is activated by the variable speed trigger. The speed of the drill is directly proportional to the amount of pressure applied to the trigger.
- To start the drill, pull the trigger.
- To increase speed, apply more pressure to the trigger.
- To stop the drill, release the trigger.
5.2 Forward/Reverse Operation
The forward/reverse selector switch is located above the trigger.
- Push the selector to the left for forward rotation (for drilling and driving screws).
- Push the selector to the right for reverse rotation (for removing screws or backing out drill bits).
- Position the selector in the center to lock the trigger and prevent accidental starting.
5.3 Using the LED Work Light
The LED work light, located below the chuck, activates automatically when the trigger is pulled, illuminating the immediate work area. This feature is particularly useful in low-light conditions.
5.4 Monitoring Battery Charge (Fuel Gauge)
The LED fuel gauge on the side of the unit provides an approximate indication of the remaining battery charge. Refer to the indicator lights to determine when recharging is necessary.
5.5 Drilling and Driving Techniques
When drilling or driving, apply steady, even pressure. For driving screws, start at a lower speed to prevent stripping the screw head or damaging the workpiece. Increase speed as needed. For drilling, ensure the drill bit is appropriate for the material and apply consistent pressure.

6. Maintenance
6.1 Cleaning
Keep the tool's air vents clear to prevent overheating. Use a clean, dry cloth to wipe down the exterior of the drill. Do not use harsh chemicals or abrasive cleaners. Never immerse the tool in liquid.
6.2 Storage
Store the drill in a dry, secure location away from children and direct sunlight. Ensure the forward/reverse selector is in the center (locked) position to prevent accidental activation. For long-term storage, it is recommended to store the battery with a partial charge.
6.3 Battery Care
To maximize battery life, avoid completely draining the battery before recharging. While the battery is internal, proper charging habits contribute to its longevity. Avoid storing the drill in extreme temperatures.
