Ryobi HD500 specifications Using Depth Gage ROD, To Adjust Drilling Mode

INSTALLING AUXILIARY HANDLE (Continued)

4.Align tabs on depth gage clamp with slots in threaded hole in motor housing. NOTE: Depth gage clamp can be rotated 180° so that depth gage rod will fit on either side of motor housing.

5.Carefully start the fine screw threads (#3/8-24) into fine threaded hole in motor housing and tighten securely. DO NOT cross thread handle bolt in motor housing.

To prevent thread damage and possible loss of control, auxiliary handle should be checked periodically for tightness.

DO NOT operate hammer drill with handle loose or with depth gage clamp removed. In addition to securing depth gage rod to your hammer drill, depth gage clamp also provides the proper amount of handle screw thread engagement when depth gage rod is not being used.

USING DEPTH GAGE ROD

See Figure 7.

A depth gage rod has been packed with your hammer drill to assist you in controlling the depth of drilled holes.

1.Install depth gage rod thru depth gage clamp as shown in figure 7.

2.Adjust depth gage rod so that the drill bit extends beyond the end of the rod to the required drilling depth.

3.Securely tighten auxiliary handle against depth gage clamp. This secures depth gage rod at desired depth of cut. It also secures auxiliary handle.

When drilling holes with the depth gage rod installed, the desired hole depth has been reached when the end of the rod comes in contact with the surface of the material being drilled.

TO ADJUST DRILLING MODE

See Figure 8.

To adjust for type of drilling, slide adjustment button on side of motor housing up to hammer mode or down to drilling mode. For your convenience a hammer symbol and drill bit symbol have been molded into adjustment button.

NOTE: Adjustment button may be difficult to slide when changing drilling modes. If this situation occurs, turn you hammer drill on and slide adjustment button while drill is running.

WARNING:

Your hammer drill has not been designed for reverse hammering.

We recommend that you use carbide-tipped bits and select hammer mode when drilling in hard materials such as brick, tile, concrete, etc.

We recommend that you select normal drill mode when drilling with twist drills, hole saws, etc. in soft materials.
