Safety Recommendations - Black & Decker BDSG500 Linea PRO Instruction Manual

Notes:
a. Use only 1" (25 mm) long bits that are designed for
use in driving drywall screws.
b. Make sure the bit size is correct for the drywall screws
being driven. This will usually be a #2 size.
Replacing the magnetic bit holder (Fig. F)
If the magnetic bit holder becomes worn or damaged, it
must be replaced. The replacement bit holder must be of
the same dimensions as the original and have the ANSI
retention groove on the end that is inserted into the tool.
1. Remove the nosepiece (2) by turning it counter clockwise.
Note: Do not use pliers on the nosepiece. Only use
your hand.
2. Grasp the screwdriver bit (7) with pliers and pull it out
of the magnetic bit holder (8).
3. Grasp the large end of the bit holder with pliers and
pull it straight out of the screwdriver spindle (9).
4. Reverse the process by inserting the replacement
magnetic bit holder into the tool.
Note: When inserting the replacement for magnetic
bit holder, gently tap it into place to make sure it is
fully inserted. Grasp the large end of the magnetic bit
holder to ensure the retention groove (10) is holding
the magnetic bit holder in place in the tool.
5. Reinstall the screwdriver bit and nose piece.

SAFETY RECOMMENDATIONS

Check the following every time you use the screwdriver:
1. Wear safety glasses or a mask.
2. Use hearing protection.
3. The screwdriver tip is the right size and it is
in good condition.
4. No power cables "live" where you are inserting the screws.
Note: Failure to follow these safety rules will significantly
increase the risk of injury.
Adjusting the screwdrive bit depth (Fig. G)
It is important to control the depth to which the drywall
screw will be driven. Over driving the screw will drive the
screw too deep and break the outer paper layer of the
drywall. Under driving the screw will leave the screw head
above the drywall surface making it impossible to properly
finish the drywall.
The depth control system is made up of the depth stop (1)
and the depth adjuster (2).
Warning! The following adjustments should always be
verified using a scrap piece of drywall to avoid damaging
the "good" drywall sections.
1. Rotate the depth adjuster counter clockwise until
approximately 1/4" of the screwdriver bit extends
beyond the depth stop.
2. Place a drywall screw onto the screwdriver bit. The
magnetized bit will hold the screw onto the bit.
Note: Before driving the screw, press the screw
point into the drywall and make sure the screw is
perpendicular to the drywall.
3. Press the screw against the drywall with steady even
pressure and squeeze the trigger switch. The clutch
in the tool will engage and the screw will be driven to
the preset depth.
4. If the screw is not driven deep enough, the head of the
screw will not be recessed into the drywall (Fig. H). In
this case, turn the depth adjustment sleeve clockwise
until the correct depth has been achieved. If the
screw is driven too deep, it will be recessed too far
into the drywall and the outer paper of the drywall
will be fractured (Fig. I). In this case, turn the depth
adjustment sleeve counter clockwise until the correct
depth has been achieved. Fig. J illustrates the correct
depth for the screw to be driven.
Note: For each revolution the depth adjustment
sleeve is rotated, the depth will increase/decrease
approximately 1/16" (1.6 mm).
Tips for driving drywall screws
f Always drive the screws perpendicular to the drywall
so the heads are properly countersunk. They should
never be driven at an angle.
f Support the tool with both hands wherever possible.
This will provide better control over the tool help
eliminate screws being driven at an angle.
f Place the drywall screw on the screwdriver bit. The
magnetic bit holder will hold any steel screw for easy
starting.
f Press the screw against the drywall with steady even
pressure and squeeze the variable speed trigger switch.
The clutch in the tool will engage and the screw will be
driven to the preset depth. Once fully driven, the
clutch will make a chattering sound until the variable
speed trigger is released.
f When the screw is properly driven, the screw head will
be slightly countersunk into the drywall without
breaking the outer drywall paper. At this point, the
clutch will release to prevent over driving the screw.
This will result in minimum work to fill the holes and
taping the seams.
f The belt clip allows you to conveniently attached the
screwdriver to your belt. This will allow you to use both
hands for positioning the drywall.
Removing drywall screws (Fig. K)
To remove drywall screws, remove the depth stop (1)
to expose the screwdriver bit.
