SELECTING THE DRILLING MODE PC650HD (FIGURE G)
• For drilling in masonry, set the drilling mode selector (5) to the "hammer symbol"
position.
• For drilling in other materials and for screwdriving, set the drilling mode selector (5) to
the "drill symbol" position.
TWO-GEAR SELECTOR PC650HD (FIGURE H)
• For drilling in steel and for screwdriving applications, turn the two-gear selector (4) into
position 1 by aligning the number with the mark on the housing (1st gear). Also when
using larger diameter bits in wood turn the two gear selector into position 1.
• For drilling in materials other than steel and when using smaller diameter bits, turn the
two-gear selector (4) into position 2 by aligning the number with mark on the housing
(2nd gear).
SETTING THE DRILLING DEPTH PC650HD (FIGURE D)
• Slacken the side handle (9) by turning the grip counterclockwise.
• Set the depth stop (8) to the desired position. The maximum drilling depth is equal to
the distance between the tip of the drill bit and the front end of the depth stop.
• Tighten the side handle by turning the grip clockwise.

SWITCHING ON AND OFF

• To switch the tool on, press the variable speed switch (1). The tool speed depends on
how far you press the switch.
• For continuous operation, press the lock-on button (2) and release the variable speed
switch. This option is available only at full speed.
• To switch the tool off, release the variable speed switch. To switch the tool off when in
continuous operation, press the variable speed switch once more and release it.
:
The drill should only be locked ON when it is held stationary in a drill
press stand or other means; NOT BY HAND! Never unplug the tool with the locking
feature engaged. To do so will cause the tool to start immediately the next time it is
plugged in.
DRILLING
• Always unplug the drill when attaching or removing accessories. When attaching
accessories in the drill chuck, it is important to securely tighten the chuck using all
three holes to prevent slippage. When using a keyless chuck, hand tighten firmly.
• Use sharp drill bits only.
• Support and secure work properly, as instructed in the Safety Instructions.
• Use appropriate and required safety equipment, as instructed in the safety
instructions.
• Secure and maintain work area, as instructed in the safety instructions.
• Run the drill very slowly, using light pressure, until the hole is started enough to keep
the drill bit from slipping out of it.
• Apply pressure in a straight line with the bit. Use enough pressure to keep the bit
biting but not so much as to stall the motor or deflect the bit.
• Hold the drill firmly with both hands to control its twisting action. One hand
should be placed on the side handle.
• Drills equipped with a side handle must use the side handle.
• DO NOT CLICK THE TRIGGER OF A STALLED DRILL OFF AND ON IN AN
ATTEMPT TO START IT. DAMAGE TO THE DRILL CAN RESULT.
• Minimize stalling on breakthrough by reducing pressure and slowly drilling through the
last part of the hole.
• Keep the motor running while pulling the bit out of a drilled hole. This will help reduce
jamming.
