Bosch Power Tools AG40-85PD-2P manual Functional Descriptions, Assembly Instructions, Hand Shield

Functional Descriptions

Electronic Clutch:

The electronics in the power tool detects situations where the wheel or accessory may be at risk to bind. The electronics prevents further rotation of the drive spindle by switching the power tool off (it does not prevent kickback). To resume operation, turn on/off switch to the off position, then restart tool.

Constant Response Circuitry:

Helps maintain near constant RPMs between no-load and load conditions.

Soft Start:

Helps reduce stress on the motor that occurs from a high torque start. Helps bring accessory smoothly up to speed.

Automatic Restart Protection:

Helps prevent accidental startups after power has been interrupted, e.g. the tool was

unplugged with the switch locked in the on position. To resume operation, turn on/off switch to the off position, then restart the tool.

Overload Protection:

Helps protect tool from excessive heat that may damage motor. If tool stops or slows during operation, allow motor to cool for 30 seconds by running no-load. If the overload protection stops the tool repeatedly, excessive force is causing the tool to overload. Stop excessive force and readjust work piece to reduce force applied.

Variable Speed:

Allows the grinders RPM to be adjusted for greater versatility to match needs of specific applications.

Assembly Instructions

Lock Nut & Backing Flange

Your tool is equipped with a threaded spindle for mounting non-threaded hub accessories. Always use the supplied backing flange with a lock nut. Inner flange is keyed to output shaft. Always ensure that arbor diameter matches accessory diameter. Accessories that run eccentrically may burst. (Fig. 3)

Installing Side Handle

The side handle is used to control and balance the tool. Securely thread handle into either side of gear housing, depending on personal preference, comfort, operation being performed. The handle should always be installed onto the guard protected side of the tool. Use the side handle for safe control and ease of operation (Fig. 4).
