The HLA 66 is a battery-powered long-reach hedge trimmer that makes it easy for you to trim tall or wide hedges across your property.



The cutter bar is adjustable by 115° and can be folded right over for neat and compact storage. The loop handle means you can easily control the hedge trimmer, particularly when using it to trim tall hedges.

It also comes with a single strap harness as standard to help balance the tool, especially when using it for longer periods of time. The double-sided blades give you a precise finish on your hedges too so you can be sure you'll get the job done right the first time.

#1 Cleaning your HLA 66

When you have finished using the hedge trimmer, remove the battery and wipe clean with a soft, damp cloth. We also suggest spraying a little resin solvent onto the blades to remove sap or resin, protect them from corrosion and stop them getting stuck together.

#2 Looking after your battery

Don't use a damp or wet battery in your HLA 66 and avoid using them in extreme temperatures (very hot or very cold).

#3 Storing your HLA 66

Store your HLA 66 in a clean and dry area and keep out of the reach of children at all times.
