SAFETY SYMBOLS
The purpose of safety symbols is to attract your attention to possible dangers. The safety symbols
and the explanations with them deserve your careful attention and understanding. The symbol
warnings do not, by themselves, eliminate any danger. The instructions and warnings they give are
no substitutes for proper accident prevention measures.
WARNING Be sure to read and understand all safety instructions in this Operator’s Manual,
including all safety alert symbols such as “DANGER,” “WARNING,” and
“CAUTION” before using this tool. Failure to follow all instructions listed below may result in electric
shock, re, and/or serious personal injury.
The denitions below describe the level of severity for each signal word. Please read the manual and
pay attention to these symbols.
This is the safety alert symbol. It is used to alert you to potential personal
injury hazards. Obey all safety messages that follow this symbol to avoid
possible injury or death.
DANGER DANGER indicates a hazardous situation which, if not avoided, will result in
death or serious injury.
WARNING WARNING indicates a hazardous situation which, if not avoided, could result
in death or serious injury.
CAUTION CAUTION, used with the safety alert symbol, indicates a hazardous situation
which, if not avoided, will result in minor or moderate injury.
Damage Prevention and Information Messages
These inform the user of important information and/or instructions that could lead to equipment or
other property damage if they are not followed. Each message is preceded by the word “NOTICE”,
as in the example below:
NOTICE: Equipment and/or property damage may result if these instructions are not followed.
WARNING The operation of any power tools can result in foreign
objects being thrown into your eyes, which can result in
severe eye damage. Before beginning power tool operation, always wear
safety goggles or safety glasses with side shields and a full face shield when
needed. We recommend a Wide Vision Safety Mask for use over eyeglasses
or standard safety glasses with side shields. Always use eye protection which
is marked to comply with ANSI Z87.1.

SAFETY RULES FOR COLLATED SCREW MAGAZINE
WARNING Read all safety warnings, instructions, illustrations and specications
provided with this power tool. Failure to follow all instructions listed below may
result in electric shock, re and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE
The collated screw magazine is designed to
only be used with the FLEX FX1611 drywall
screwdriver.
Observe all operating instructions and
safety regulations contained in the manual
for the FLEX FX1611 drywall screwdriver.
Before use, ensure that the magazine is
properly attached to the power tool.
Avoid body contact with grounded (or
earthed) surfaces such as pipes, radiators,
ranges and refrigerators. There is an
increased risk of electric shock if your body is
grounded.
Detach the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
When driving screws, never reach into
the magazine. Keep hands clear of the
advancing mechanism and the spot where
the screw is being driven.
Do not use the magazine as a gripping
surface.
Hold power tool by insulated gripping
surfaces, when performing an operation
where the fastener may contact hidden
wiring. Fasteners contacting a “live” wire may
make exposed metal parts of the power tool
“live” and could give the operator an electric
shock.
Use only screw strips with screw sizes #6,
#7 and #8 with this magazine. Only insert
screw strips when the screwdriver is turned
off and the trigger is locked.
WARNING
• Some dust created by power sanding, sawing,
grinding, drilling and other construction
activities contains chemicals known to the
State of California to cause cancer, birth
defects or other reproductive harm. Some
examples of these chemicals are:
– Lead from lead-based paints.
– Crystalline silica from bricks, cement, and
other masonry products.
– Arsenic and chromium from chemically-treated
lumber.
• Your risk from these exposures varies,
depending upon how often you do this type
of work. To reduce your exposure to these
chemicals:
– Work in a well-ventilated area.
– Work with approved safety equipment, such
as dust masks that are specially designed to
lter out microscopic particles.
– Avoid prolonged contact with dust from power
sanding, sawing, grinding, drilling, and other
construction activities. Wear protective clothing
and wash exposed areas with soap and water.
Allowing dust to get into your mouth or eyes or
to lie on the skin may promote absorption of
harmful chemicals.

ADJUSTMENTS
WARNING Detach the battery pack
from the drywall
screwdriver and lock the variable-speed
trigger switch “OFF” by placing the
direction-of-rotation selector in the center
position.
SETTING THE SCREW LENGTH
CAUTION Do not adjust the screw
length while a screw strip
is in the magazine. Remove the screw strip
prior to making adjustments.
This magazine is designed for screws that are
1 – 2 inches (25 – 51 mm) long. Failure to set
the correct screw length can cause screws to
not be driven accurately which can result in the
failure to advance the next screw or screws
not being screwed-in properly. The shoe has
the specic length marks for the most common
screw lengths. The arrow points at the length
mark indicating the current screw length
(Fig. 6a).
a. Slide the screw length adjustment tab to the
left (Fig. 6a).
b. While holding the screw length adjustment tab
in place, adjust the shoe to the desired length
by pulling the shoe out or pushing it into the
magazine until the arrow is aligned with the
desired length mark (Fig. 6a).
c. Release the screw length adjustment tab.
Make sure that the locking pin on the other
side of the magazine has fully returned and is
in the desired marked depth position (Fig. 6b).
SETTING SCREW-IN DEPTH (FIG. 7)
Use the dial for screw-in depth to set the
desired screw-in depth.
Turn the dial up (or clockwise) for driving
the screws deeper into the workpiece, or
down (counterclockwise) to allow more of the
screwhead to stick out from the workpiece. The
actual setting position is shown on the screw-in
depth indicator.
Upon setting, drive some screws for testing and
use the dial to adjust the depth, if required.
