This time by using the battery angle grinder, we managed to make an improved version of the angle grinder hack 4.

Step 1: Angle Grinder

We decided to use the particular angle grinder as it has a protective mechanism which automatically stops when more power than the one allowed has been exerted.

Therefore, we are protected from any accidents that might happen in case the tree-cutters make a kick back and the chain hits the human body.

Step 2: Lubricate the Chain

After the experiment that we had done on the previous hack, we found it necessary to lubricate the chain bar as well as the chain itself in order to avoid the rising of the temperature of both the bar and the chain. Doing this, we managed to increase the existence of the chain. The lubrication is achieved using an automated mechanism that when it orbits, it releases a quantity of oil on the chain derived from a pot that is placed on the chain bar. Another important advantage of this structure is that is portable so that the user is able to move it around easily and cut the wood that he needs to use.

However, its only disadvantage is its limited power and consequently, only a small chain bar and a cutting chain can be used.

Step 3: Video

Although, the power is obviously less than the equivalent hack 4, the advantages overweigh in a great extent the disadvantages as well as it provides much more security than the previous version.
