Three Speed Gear Train, Keyless Chuck

OPERATION

THREE SPEED GEAR TRAIN

See Figure 11.

The hammer drill has a two-speed gear train that provides a high speed of approximately 1,400/min and a low speed of approximately 400/min (stated speeds are with the trigger switch in the “Full-on” position).

Follow these steps to adjust the speed.

■For super high speed: Slide the three-speed gear train switch to “3.”

■For high speed: Slide the three-speed gear train switch to “2.”

■For low speed: Slide the three-speed gear train switch to “1.”

Note: If you have difficulty changing from one gear range to the other, turn the chuck by hand until the gears engage.

CAUTION:

To prevent gear damage, always allow chuck to come to a complete stop before changing the speed or the direction of rotation.

KEYLESS CHUCK

See Figure 12.

A keyless chuck has been provided with your drill to allow for easy installation and removal of bits. As the name implies, you can hand tighten or release drill bits in the chuck jaws. Grasp and hold the collar of the chuck with one hand. Rotate the chuck body with your other hand. The arrows on the chuck indicate which direction to rotate the chuck body in order to GRIP (tighten) or RELEASE (unlock) the drill bit.

WARNING:

Do not hold the chuck body with one hand and use the power of the drill to tighten chuck jaws on drill bits. Chuck body could slip in your hand or your hand could slip and come in contact with rotating drill bit. This could cause an accident resulting in serious personal injury.
