4. Setup and Preparation
4.1 Charging the Battery
- Ensure the battery charger is connected to a suitable power outlet.
- Insert the battery pack into the charger. The charger's indicator light will show the charging status.
- Allow the battery to fully charge before first use. Refer to the charger's manual for specific charging times and indicators.
- Once charged, remove the battery from the charger.
4.2 Installing the Battery
- Ensure the tool's trigger is not engaged.
- Align the charged battery pack with the battery compartment at the base of the tool's handle.
- Slide the battery pack firmly into place until it clicks, indicating it is securely locked.
- To remove, press the battery release button (if present) and slide the battery out.
4.3 Installing Dies
- Ensure the tool is off and the battery is removed for safety.
- Retract the ram fully by pressing the return button.
- Open the die retainer pin or mechanism on the crimping head.
- Insert the appropriate "U" type dies for the specific connector and cable size you are working with.
- Close and secure the die retainer pin. Ensure dies are properly seated and aligned.
5. Operating Instructions
5.1 Pre-Operation Check
- Verify the correct dies are installed for the application.
- Ensure the battery is fully charged and securely installed.
- Inspect the tool for any visible damage or loose parts.
- Confirm the work piece (cable and connector) is clean and prepared according to manufacturer specifications.
5.2 Performing a Crimp
- Open the crimping head by pressing the return button until the dies are fully retracted.
- Position the cable and connector within the open dies. Ensure the connector is properly seated and aligned for the crimp.
- If necessary, rotate the crimping head to achieve the optimal working angle.
- Press and hold the trigger switch. The dies will advance rapidly until they contact the connector, then slow down as crimping pressure builds.
- Continue holding the trigger until the tool's internal bypass system audibly "bypasses" (a distinct click or hiss), indicating that optimal crimping pressure has been reached.
- Release the trigger switch.
- Press the return button to retract the ram and open the dies.
- Remove the crimped connector and inspect the crimp for quality and completeness.
5.3 Single-Handed Operation
The REC-B6510 is designed for single-handed use. This allows the operator to hold the tool with one hand while the other hand is free to position the cable or connector, particularly useful in overhead or confined spaces. Ensure a firm grip and stable footing when operating with one hand.
6. Maintenance and Care
6.1 General Cleaning
- After each use, wipe down the tool with a clean, dry cloth to remove dirt, dust, and debris.
- Pay special attention to the crimping head and die areas to prevent accumulation that could affect performance.
- Do not use harsh chemicals or solvents that could damage the tool's housing or internal components.
6.2 Battery Care and Storage
- Store batteries in a cool, dry place away from direct sunlight and extreme temperatures.
- Do not store batteries in a discharged state for extended periods. Recharge them periodically if not in use.
- Avoid dropping or physically damaging battery packs.
- If a battery pack becomes hot during use or charging, discontinue use and allow it to cool before handling.
6.3 Die Maintenance
- Keep dies clean and free of debris.
- Inspect dies regularly for wear, cracks, or damage. Replace worn or damaged dies immediately to ensure proper crimps.
