Assembly Instructions
Before operating your Black & Decker trimmer‚ proper assembly is essential for safety and performance․ Begin by securely attaching the guard – never operate the trimmer without it installed‚ as this can lead to overheating and potential injury․ Ensure the guard clicks firmly into place․
If your model utilizes a spool‚ carefully install it according to the diagram in this manual․ Proper spool installation ensures consistent line feed during trimming․ Adjust the handle to a comfortable ergonomic position‚ ensuring a secure grip and optimal control․ Double-check all connections before proceeding to operation․
Attaching the Guard
The guard is a critical safety component of your Black & Decker trimmer and must be securely attached before each use․ Align the guard with the designated mounting points on the trimmer housing․ Push firmly until you hear a distinct “click‚” indicating a secure connection․
Ensure the guard is properly positioned to deflect debris away from the user․ Regularly inspect the guard for cracks or damage; a damaged guard should be replaced immediately․ Operating the trimmer without the guard significantly increases the risk of injury from flying debris and can also cause the motor to overheat․ Prioritize safety – always guard up!
Installing the Spool (if applicable)
For Black & Decker trimmers utilizing a spool system‚ begin by ensuring the trimmer is switched off and the battery is disconnected․ Locate the spool housing‚ typically near the trimmer head․ Lift the retaining latch to access the spool compartment․ Insert the new spool‚ ensuring the line feeds in the correct direction as indicated by the arrows on the housing․
