2. Installation
The Streamlight Battery Door is a direct replacement for the original battery door and switch assembly on TLR-1 and TLR-2 weapon lights. Installation requires careful handling of a small pin.
2.1 Required Tools
- Small flathead jeweler's screwdriver (optional, for pin alignment)
2.2 Installation Steps
- Remove the Old Battery Door: Carefully push out the retaining pin from your existing battery cap assembly. This pin secures the battery door to the flashlight body.
- Position the New Battery Door: Place the new Streamlight Battery Door into the slot on the flashlight body where the old cap was removed.
- Insert the Retaining Pin: Slide the retaining pin back through the flashlight body and the new battery door.
- Aligning the Pin (if needed): If the pin does not slide easily, use a small flathead jeweler's screwdriver to gently lift or adjust the internal components of the battery door assembly to align the pin holes. Do not force the pin.
- Secure the Pin: Ensure the pin is fully inserted and secure, holding the new battery door firmly in place.
Note: Proper installation ensures the battery door functions correctly, providing both power connection and environmental sealing for your TLR-1 or TLR-2 flashlight.
3. Operation
Once installed, the battery door facilitates the power connection for your Streamlight TLR-1 or TLR-2 flashlight. Ensure the door is fully closed and secured by the retaining pin for proper operation and to maintain the flashlight's water resistance.
- Battery Insertion: Open the battery door, insert the correct batteries (not included) according to the polarity markings inside the flashlight, then close the door securely.
- Switch Functionality: The battery door assembly includes the switch mechanism for momentary-on or constant-on light functions, depending on your TLR model. Verify that the switch operates smoothly after installation.
4. Maintenance
Regular maintenance of the battery door ensures the longevity and reliability of your Streamlight flashlight.
- Inspection: Periodically inspect the battery door and its gasket for any signs of wear, damage, or corrosion. A damaged gasket can compromise the flashlight's water resistance.
- Cleaning: Clean the battery door and contact points with a dry, lint-free cloth. Avoid using abrasive cleaners or solvents.
- Gasket Care: If the gasket appears dry, a small amount of silicone grease can be applied to maintain its flexibility and sealing properties. Ensure the gasket is seated correctly before closing the door.
