## Questions & Answers

**Q: Where can I find instructions - How to change and reload line?**
A: Search on you tube. Lovely fella gives very clear instructions.

**Q: Hi bought this but twice the oil has come out black when it goes in red and the engine has been boiling can anyone tell me is this normal, thank you**
A: The engine oil will change colour over time. This is normal. Engine reaches high temperatures especially around the exhaust area. Again this is normal. Use 60ml of SAE15w40 engine oil.

**Q: Where can you get replacement lines and brush cutter blades from?**
A: You can get replacement line anywhere just load the spool not sure about the blade but it should last a long time.

**Q: How long does the petrol last ?**
A: Not as long as I'd hoped but long enough to strim a  45 mtr by 2 mtr path of very dense weeds and brambles using full throttle.  Make no mistake this is a great tool and the petrol tank is irrelevant as its pure petrol so no mixing.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product, price and 24 hour delivery.
*by M***H on 11 September 2018*

Great product, price and 24 our delivery. This is a four- stroke petrol strimmer that I have used to replace a 2-stroke machine.Very much lighter and quieter and smoother to use. The quality of the product is vastly superior to the cheaper Chinese generic strimmers (52cc). The full harness is also great to use and has an easy release clasp. Delivered very quickly (24 hours) and I am delighted with the end product. Easy to assemble but suggest the owners manual is not that good. I looked at the video on You Tube which was much easier to follow. The only extra needed is 0.6 litres of 5/30 semi-synthetic engine oil and they provide a filling bottle to help you with that process.

### ⭐ Don’t waste your time, it will break.
*by T***Z on 21 March 2020*

Updated again down to 1 star. Hyundai, after some chasing, sent a replacement lower drive shaft under warranty. It failed again in exactly the same way after 30 minutes strimming grass. Despite still being under warranty, refund is not possible. The sprung bearing design that stops the drive shaft from rotating might as well be made from cardboard, it is a useless design. Iwehn it fails the whole drive shaft rotates. If I cannot get another replacement (which would probably also break) I will need to improvise sow form of repair.Original reviews: Updated to 2 stars (from 4). Original review below. Engine is running well after a full season of occasional use strimming an allotment and one significant outing clearing an allotment with the brush cutter. But seriously let down by the steel spring breaking on the recoil starter; which I mended myself, as I have yet to find the claimed UK spares network. And yesterday, the pop-up bearing, which secures the bottom half of the drive shaft, simply failed. No idea if this can be repaired or replaced. So the engine and other mechanics are let down by poor build quality. If used commercially, it would have failed in the first week. Here is my original review: It’s a great, reliable machine, well built. But why use a plastic bump head that is awkward to adjust chord, and in my case, broke because I didn’t refit it properly with the awkward catches and spring? I replaced it with a Hawks Head universal bump head, which is brilliantly easy and highly recommended. Together, they make a great machine!

### ⭐⭐⭐⭐ Works well
*by P***O on 13 January 2019*

So far works well. Light and easy to use.
