Frequently Asked Questions - GL420CX BLACK & DECKER
How to replace the cutting line?
Unplug the mower, remove the cutting head by turning it counterclockwise. Cut two lengths of 120 mm line and insert them into the provided slots. Wind the line in the indicated direction, then reassemble the head. Check that the line unwinds correctly before using the device again.
What type of extension cord can I use?

How to adjust the cutting height?

Why won't the mower start?
Check that the device is properly plugged in and that the cable is not damaged. Then check the safety lock: you must press the lock button before pressing the trigger. If the problem persists, check the fuse in the circuit.

How to avoid jams?
To avoid jams, mow dry grass and do not exceed the cutting width of 30 cm. Advance at a moderate pace and do not cut on overly sloping ground. Clean the cutting head regularly to prevent debris buildup.
What is the warranty for the mower?
The legal warranty is 2 years from the date of purchase. It covers defects in material and workmanship. Keep the invoice or receipt as proof of purchase. Wear parts such as the nylon line are not covered.
