1. Blade
The blade is made of tungsten steel with a long life and cuts the rubber material easily. It is designed to cut rubber material and rubber material only.If used to cut a wood material
the blade will chip and crack. There is no factory warranty on the blade just like a kitchen knife.
2. Gears and Gear Ribs
The gears and gear ribs as well as other parts in the cutter are good to work on the rubber wall base for years. But if used to cut other flooring material like wood or laminate flooring or even LVT flooring, it may cause the damage on the gear or gear ribs. The cutter is designed to cut rubber material, so any damage on the gear and gear ribs will be on user's risk and cost. Keep in mind that this cutter, its mechnical structure and all parts, is especially designed for cutting rubber base ONLY.
3. Square cut
If cutting in the middle of the wall base, you may not get a perfectly square cut. What you need to do is to make a second cut to cut about 1/8" on the previous cut to get a perfect 90 degree cut.
4. Material moving during cutting process
Just let it go, do not hold the material or press it down. Only thing you need to do is to push the material flush with the guide bars on either side of the table in order to get a desired cut.
