Push Blocks
When used correctly, a push block reduces the risk of injury by keeping hands away from the blade while cutting. In the event of an accident, a push block often takes the damage that would have otherwise happened to hands or fingers.
Using a Push Block
A push block can be used in place of or in addi- tion to a push stick for feeding workpieces into the blade. Due to their design, push blocks allow the operator to apply firm downward pressure on the workpiece that could not otherwise be achieved with a push stick.
The push block design on this page can be used in two different ways (see inset Figure below). Typically, the bottom of the push block is used until the end of the workpiece reaches the blade.
The notched end of the push block is then used to push the workpiece the rest of the way through the cut, keeping the operator's hands at a safe distance from the blade. A push stick is often used at the same time in the other hand to sup- port the workpiece during the cut (see "Using a Push Stick" on previous page).
