ADJUSTING THE SPEED

See Figure 10.

The hammer drill has a three-speed gear train that provides a super-high speed of approximately 2,200/min., a high speed of approximately 750/min. and a low speed of approximately 370/min. (stated speeds are no-load with the trigger switch in the “Full-on” position).

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

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

nFor 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:

Never change gears while the tool is running. Failure to obey this caution could result in serious damage to the drill.
