INSTALLING AND REMOVING DRILL AND SCREWDRIVER BITS

1.CAUTION: Always set reversing button to center (locked OFF) position when installing and removing bits.

2.The three-jaw chuck is designed for self-centering of the bit. Open jaws large enough by turning outer sleeve (A) Fig. 2, counterclockwise, when viewing the chuck from the bit end, so that bit shank can be inserted easily.

3.Clean and insert smooth end of bit as far as it will go into the chuck, or up to the flutes for small bits.

4.While holding the bit with one hand, turn outer sleeve (A) Fig. 2, clockwise until the bit is gripped in the chuck.

5.Tighten chuck by holding chuck ring (B) Fig. 2, with one hand while turning outer sleeve (A) clockwise with other hand. Tighten securely.

WARNING: Do not operate drill motor while installing or removing bits. Operating drill motor can cause bit to be thrown from chuck causing personal injury.

a hammer (impact) position. Lowest torque is

 

 

avaible at setting #1, with maximum torque

 

 

 

available at the “Drill” setting. The amount of

 

 

 

output torque may be adjusted by rotating

delicate work, while higher torque settings

 

 

 

are used for driving larger screws. The “Drill” position is used for drilling and for driving very large screws. The hammer position is used when “impacting” is needed to assist in the drilling operation such as when drilling in concrete, bricks, etc.

TWO-SPEED GEAR SHIFT

The Models 877 and 887 Cordless Hammer Drill/Drivers have a two-speed gear shift which provides spindle speed ranges of approximately: 0 to 475 RPM (LOW) and 0 to 1450 RPM (HIGH) for Model 877; 0-500 RPM (LOW) and 0-1500 RPM (HIGH) for Model 887. To change speed ranges: release trigger switch to stop motor and then slide speed selector (A) Fig. 4, toward rear for HIGH speed or toward front for LOW speed.

The low speed position is normally used when drilling larger holes and when driving or removing screws. The high speed position is normally used for drilling small holes.
