First, read the English article below.

Set the miter saw to the angle it will need to cut at. Use the included instructions for your machine, as each is different. Place the wood on the machine so that it is upside down, when possible. Always make sure you know where the short and long sides of your wood need to be. Make use of a laser guide if your machine has one (most newer machines do). If you're unsure about how a piece of wood is lined up, keep scrap wood handy to test the cut on. Testing is important.  When cutting a picture frame style cut, place the flat side on the cutting surface. When cutting a box style cut, place the flat side against the fence (or back piece of the cutting surface). If you are not using a piece long enough to hold and have your hands well out of the way of the saw, you should use clamps to hold the wood in place. Seriously, a lot of people lose fingers this way. Be careful. Usually there are a series of buttons and actions you have to take to start and lower the saw. Follow the instructions that came with the machine you have. When you lower the saw, keep your hands away and do not press down very hard. Simply guide it to where it needs to go and let the saw do the cutting. Once it's done, you can unclamp and remove your piece. 

Now, please write a short abstract for it in Indonesian. Abstract:
Sejajarkan gergaji. Sejajarkan kayu. Jepit kayu hingga tidak bergerak. Nyalakan dan turunkan gergaji. Naikkan gergaji dan tunggu sampai bilahnya berhenti bergerak.
