The main risk of injury presented by sawing using power tools comes from the saw blade. This is the case both when the tool is operational and when it is not. There is also the risk of machine kickbacks in the event of application errors. Only sharp saw blades that are in perfect condition may be used. The saw blades must be suitable and permitted for the relevant saw. Blunt or damaged saw blades can cause the machine to jam or get blocked. Injuries caused by a saw blade can be avoided by taking the following measures:
Never remove protective guards, hold them open or otherwise manipulate them.
Operate the machine with both hands, while holding it in the intended grip areas.
Cover chainsaws with a protective sleeve after use.
With all other saws (except circular saws), remove the saw blade from the saw once you have finished work.
Adjust and attach adjustable protective equipment such as the riving knife in line with regulations.
The saw must be operated firmly and securely when working. You should select the feed pressure such that the saw is not jammed or blocked. This could cause recoil torques.
