Bosch Power Tools 4100DG manual Basic Table Saw Operation, Safety Power Switch, Smart Guard System

Basic Table Saw Operation

Safety Power Switch

NOTE: This table saw has a safety feature that helps prevent accidental starting.

To turn saw on: lift switch lever by pinching side walls and pulling up. This action starts the saw (Fig. 30)

To turn off power: push switch lever down to its original position (Fig. 31).

To prevent unauthorized use, the switch can accommodate a padlock with a long, 3/16" or 1/4” diameter shackle (not provided with table saw), (Fig. 31).

Smart Guard System

The Bosch Smart Guard has been designed for modularity, enabling the use of multiple combinations of the three main components – Main barrier guards, Anti-kickback device, and riving knife. Additionally, the riving knife can be quickly adjusted to three positions (high, middle, and stored), depending on the application requirement.

❶Component Parts (figure 32):

Riving Knife

The Riving Knife is the central element of the Bosch Smart Guard blade guarding system, serving as the attachment point for both the Main Barrier Guard and the Anti-Kickback Device. In the event that the Main Barrier Guard and Anti- Kickback Device are removed, the Riving Knife maintains its functionality as material splitter, and is adjustable to three positions. Because of this adjustability, the Riving Knife can

be appropriately positioned	for all cutting applications.
❷ Main Barrier Guard

The main guard is comprised of a pair of plastic barriers attached to the metal upper barrier guard. The side barriers (one to the left and one to the right of the blade) operate independently of one another, maintaining maximum blade coverage during cutting operations. The main guard incorporates a quick-connect attachment point and can be attached or removed from the blade guarding system independent of the Anti-Kickback Device and Riving Knife.

Note: To best secure the main guard for transport, adjust the blade to its lowest position. This keeps the guard tight to the table surface and prevents damage related to the

❸ guard swinging during transport.

Anti-Kickback Device

In the event of kickback, the Anti-Kickback Device, (also known as dogs, or pawls) is intended to help prevent the board from being thrown in the direction of the user. The sharp teeth of the pawls are intended to “catch” the material in the event of kickback.

Attachment/Removal

(see page 26 for detailed instructions)

The three primary components of the Smart Guard blade guarding system are designed for rapid attachment, adjustment, and/or removal without the need for additional tools.

The Main Barrier Guard component can be quickly attached and detached through the use of a quick release lever. The guard is attached by seating the crossbar into the top of the Riving Knife and engaging the locking lever. Following this process in
