The diamond insert in the hub of the blade keeps falling out as soon as I start a cut. What is wrong?
DO NOT USE SAW!!!
1. switch off saw, remove cord from socket (positive electrical insulation)
2. lift table for maximum cut and check size of the washer holding the blade,
3. you should have holding nut with collar, collar is about 1 1/4 (32mm) diameter, then blade (diamond is actually universal reducing bush in some blades) and lastly you should have internal washer, again, about 1 1/4" (32mm) diameter. if your collar are smaller, you need to replace blade as not suitable for your particular model, albeit I am rather suspicious that you have wrong collared nut and internal collar. Please check if both collars are exactly this same diameter. Please check if collars cover diamond cut-out.
4. if you see discreptancy between description in 3, purchase suitable blade (external diameter is 7 1/4" (184mm), as you did not supply what model of your saw, therefore most probably shank is 5/8" (16mm),
5. mount internal bush (collar), will go correctly only in one way.
6. mount blade (pay attention to cut direction, cutting surface should be clockwise if you look at mounting shaft.
7. mount external flared nut
8. check blade for slippage and wobbliness
9. connect power cord and switch on/off
10. check saw blade againg for slippage/wobbliness
11. make test cut if 10 was correct
12. use normally
Do not forget that this is not a toy, it will cut through wood, ocassional nail and your fingers.
Opearating saw crate flying debris, always wear googles or facemask, you have only two eyes and there is no spares.
Please leave note how you go with this advice.
