Storage Tips (3)

The first thing that you should never do is store this trimmer in the outdoors – it must be stored indoors in your garage, shed or house and the charging of the battery should be done indoors also. The second thing is that you should allow it to cool down prior to storage and store in a place out of reach for children (fully recharge the battery before Winter storage). The 3rd and final storage tip is to keep the battery and charger in a cool dry place when not in use. If they battery starts to deplete very quickly after a 2.5 hours recharge time, then the time has come for the battery to get replaced.

Pros for the Flymo Cordless Grass Trimmer:

  • Cord free and cable free grass trimming solution that can tidy up after the lawnmower work or even be used for small mini gardens or small grass patches on its own
  • Slightly longer trimming runtime on the battery which can last from 25 to 33 minutes depending on trimming conditions and the level of work being carried out.
  • The length of the shaft can be extended for taller people unlike many of the cheaper lower priced trimmers seen on the market.
  • You get a reliable 2 year warranty as back up which protects your investment well into the future.
  • It includes the lawn edge facility and plant guard which is not available on the Flymo C link model or many other trimmers elsewhere
  • Assembly instructions do take a bit of work but the diagrams in the manual are laid out well which can be followed easily step by step
  • The wheeled edge support works great for clean, neat and tidy finishes around the patio edges and flower beds.

Cons for the Flymo Cordless Grass Trimmer:

  • Some brands like Spear & Jackson offer a second spare spool in the delivery where you only get 1 spool line here
  • Heavier duty work or tougher thicker conditions will deplete the battery charge a lot quicker (less than 20 mins) so be prepared in advance for this.
  • Arm fatigue will set in after 10 or 15 minutes so you may need to take regular breaks instead of trying to get it all done in the one go.
  • Lacks the superior power for cutting thicker taller meadow type grasses and lacks the power to cut large thistles and brambles (suitable for lighter type work only)

Price Guide: £90 to £130

Key Features

Many of the key features associated to this Grass trimmer are outlined in the diagram below which include the adjustable handle, the edging mode, the battery and also the shrubbing mode to mention just a few.

Auto Feed Line System

When you switch on the trimmer, a small amount of line is fed out automatically and you will hear a little noise. Don’t be alarmed when you hear this as this is normal as the line hits the line cutter sides and it comes to normality after around 5 seconds. This is the line being cut to the correct size for normal trimming functions. To feed out more line, you can stop the machine and restart again which in turn feeds out more cutting line. Releasing more line manually can also be done by pressing the manual feed button on the head and pulling the line at the same time.

Trouble Shooting:

If you come across any issues such as the line not feeding correctly or if there are excessive vibrations or if the line snaps continuously, the solutions outlined below can help you get these potential problems that may arise resolved.

What’s in the Box?

There are 10 main parts included with this grass trimmer which are all outlined and labelled below. Examples of what you can expect to see are the battery pack & charger, the upper and lower shafts, the guards and also the safety lock off switch. Each of these are numbered below

Part 5: Alternative Flymo Grass trimmers

This cordless grass trimmer is a reliable tool but it is not the cheapest to buy and if you need to buy a lower priced trimmer from Flymo, they offer 2 corded lower priced alternatives which are more designed for people who don’t mind using a cord or cable while they work and also for people who are seeking the lowest possible price.

Part 6: Conclusion & Optional Feedback

Would we recommend the Flymo Cordless trimmer? While it is not the best we have ever used, it is hard to fault it in any major way. The battery does last 25 minutes plus but it does get depleted a lot quicker with heavier duty work, so you need to keep it to normal or standard type edge trimming work to get the most of the battery.

The manual is decent with all the information one would need, and the auto feed line system worked exactly as expected with no issues experienced whatsoever. Time will tell if it continues as good as it does but for now, it did a fairly decent job to be fair.
