Keyless Chuck
A keyless chuck (1) has been provided with your drill to allow for easy installation and
removal of bits. The chuck is divided into two parts, the rear is called the collar and the
front is the body. To open and close the keyless chuck (1) grasp and hold the collar of
the chuck with one hand and 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 power of the
drill to tighten or loosen the chuck jaws. The chuck body could slip and your
hand could come in contact with a rotating accessory. This could cause an
accident resulting in personal injury.
Installing Drill/Driver Bits
•
Remove battery (13) from the drill.
•
Open or close the keyless chuck (1) to a point where the opening is slightly larger
than the drill bit you intend to use.
•
Insert the drill bit into the keyless chuck (1) ensuring the end of the drill bit does
not touch the screw inside the keyless chuck (1).
•
Tighten the keyless chuck (1) onto the drill bit as described above.
Removing Drill/Driver Bits
•
Remove the battery (13) from the drill.
•
Loosen the keyless chuck (1) as described above.
•
Remove the drill bit from the keyless chuck (1).
Note:
Do not handle drill bits without gloves as drill bits and other accessories are
sharp and can cause a personal injury.
General Hints for Drilling in all Materials
•
Always use sharp drill bits.
•
Mark the place where you would like the hole to be drilled.
•
Commence with a slow rotation speed to start the hole.
•
Reduce your pressure on the tool when the drill bit is about to break through the material.
Metal Drilling
•
Support thin material with a wooden plate.
•
Use a punch to mark the position of the hole.
•
If drilling a large hole use a small drill at first to establish a pilot hole then use the
required large size drill bit.
•
Use only HSS (high speed steel) drill bits or those recommended for metal use.
•
When drilling into iron or steel, use a cooling lubricant such as thin oil. With
aluminium, use turpentine or paraffin. With brass, copper and cast iron, use no
lubricant but withdraw the drill regularly to assist cooling.
