Ring Clamp, Extension, and Side Handle for Right Angle Drive (RAD)

For D-handle drill with RAD:

A ring clamp, extension, and side handle are supplied with the Right Angle Drive Unit. When using a right angle drive unit, attach the side handle to the ring clamp. Do not use the extension when using the ring clamp. The ring clamp with attached side handle clamps onto the right angle drive unit and can swivel 360° and locked tight in any position.

For D-handle drill without RAD:

When using the D-handle drill without the right angle drive unit, remove the ring clamp with attached side handle from the RAD, then remove the side handle from the ring clamp. Attach the side handle to the extension. The side handle can be installed on either side of the tool for right or left handed use. To install the extension with attached side handle, thread it into the socket on the desired side of the tool (for right or left-handed use) and tighten securely.

NOTE: If you have an extra ring clamp with attached side handle and extension with attached side handle, do not use the extension with attached side handle when using the right angle drive unit. Remove it from the tool.

the other side of the sleeve and turn

the drive head slightly in either direction

so the hexagonal hole in the coupling

engages the hexagonal portion of the

spindle.

NOTE: Attaching the drill chuck to the

side designated “low” reduces the speed

by 1/3, or 33%. Attaching the drill chuck

to the opposite side of the right angle

drill head increases the speed by 1/2,

or 50%.

3. When assembled, turn the right angle

head to the desired position and tighten

the clamping screws to secure the

unit. Thread the chuck onto the right

angle drive spindle and install the chuck

screw.

1.To remove the left-hand screw inside the chuck, remove the battery pack from the tool and open the chuck jaws. Insert a T-handle hex key into the screw inside the chuck. Turn the T-handle hex key and remove the screw. Save the screw for installing your new chuck.

2.To remove chuck: Tighten a large hex key into the chuck. Place the chuck on a workbench as shown. Strike the hex key with a soft-headed mallet to loosen the chuck. Remove the chuck by hand.
