General Safety Rules
WARNING! Read and understand all instructions. Failure to follow all instructions
listed below, may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
A. Work Area
1. Keep your work area clean and well lit. Cluttered benches and dark areas
invite accidents.
2. Do not operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases, or dust. Power tools create sparks
which may ignite the dust or fumes.
3. Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control.
B. Electrical Safety
1. Double insulated tools are equipped with a polarized plug (one blade is wider
than the other.) This plug will fit in a polarized outlet only one way. If the plug
does not fit fully in the outlet, reverse the plug. ¥f it still does not fit, contact a
qualified electrician to install a polarized outlet.
Do not change the plug in any way. Double insulation [С eliminates the need
for the three wire grounded power cord and grounded power supply system.
2. Avoid body contact with grounded surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk of electric shock if your body is
grounded.
3. Don't expose power tools to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock.
4. Do not abuse the cord. Never use the cord to carry the tools or pull the plug
from an outlet. Keep cord away from heat, oil, sharp edges or moving parts.
Replace damaged cords immediately. Damaged cords increase the risk of
electric shock.
5. When operating a power tool outside, use an outdoor extension cord marked
“W-A" or “W." These cords are rated for outdoor use and reduce the risk of
electric shock. Be sure to use an extension cord of sufficient size to prevent
overheating and loss of power to the tool.
The table below shows the correct size extension cord to use.
Cord Length Required Wire Size
25 feet 18 ga
50 feet 16 ga
75 feet 14 ga
100 feet 12 ga
C. Personal Safety
1. Stay alert, watch what you are doing and use common sense when operating
a power toot. Do not use tool while tired or under the influence of drugs,
alcohol, or medication. A moment of inattention while operating power tools
may result in serious personal injury.
2. Dress properly. Do not wear loose clothing or jewellery. Contain long hair.
Keep your hair, clothing, and gloves away from moving parts. Loose clothes,
jewellery, or long hair can be caught in moving parts.
3. Avoid accidental starting. Be sure switch is off before plugging in. Carrying
tools with your finger on the switch or plugging in tools, that have the switch on
invites accidents.
4. Remove adjusting keys or wrenches before turning the tool on. A wrench or a
key that is left attached to a rotating part of the tool may result in personal
injury.
5. Do not over reach. Keep proper footing and balance at all times. Proper
footing and balance enables better control of the tool in unexpected situations.
6. Use safety equipment. Always wear eye protection. Dust mask, non-skid
safety shoes, hard hat, or hearing protection must be used for appropriate
conditions.
0. Tool Use and Care
1. Use clamps or other practical way to secure and support the workpiece to a
stable platform. Holding the work by hand or against your body is unstable and
may lead to loss of control.
2. Do not force tool. Use the correct tool for your application. The correct tool
will do the job better and safer at the rate for which it is designed.
3. Do not use tool if switch does not turn it on or off. Any tool that cannot be
controlled with the switch is dangerous and must be repaired.
4. Disconnect the plug from the power source before making any adjustments,
changing accessories, or storing the tool. Such preventive safety measures
reduce the risk of starting the tool accidentally.
5. Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users.
6. Maintain tools with care. Keep cutting tools sharp and clean. Properly
maintained tools, with sharp cutting edges are less likely to bind and are easier
to control.
7. Check for misalignment or binding of moving parts, breakage of parts, and
any other condition that may affect the tools operation. if damaged, have the
tool serviced before using. Many accidents are caused by poorly maintained
tools.
8. Use only accessories that are recommended by the manufacturer for your
model. Accessories that may be suitable for one tool, may become hazardous
when used on another tool.
E. Service
1. Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of injury.
2. When servicing a tool, use only the identical replacement parts. Follow
instructions in the Maintenance section of this manual. Use of unauthorized
parts or failure to follow Maintenance instructions may create a risk of electric
shock or injury.

CAUTION - Never change the direction of bit rotation while the motor is running. To
do so could damage the motor and void warranty. Always turn the tool off before
changing the direction of bit rotation.
PREPARATION BEFORE USE
TOOL PREPARATION BEFORE USE:
(a) Use An Appropriate Power Supply - The power source should conform to the
specifications stated on the nameplate. A direct current (DC) power supply can
damage the unit and cause injury. Before connecting the FD/FLYL41 to a power source,
ensure the trigger switch ts in the "off" position. The motor will start automatically if
the plug is connected to a socket with the switch in the "on" position. Pull the trigger
switch to start the unit and release it to stop. When releasing the switch, always
check that it returns to it's former position.
(b) Installing The Magazine - Push the magazine onto the magazine holder untit it
clicks firmly into position. See figure 4. The magazine is inserted onto the tool from
the motor end in the direction of the feeding mechanism. The magazine may be used
as a stand while the tool is not in use. To remove the magazine, press the clamp plate
on the side of the magazine and remove it from the magazine holder.
(c) Magazine Inner Adjustment - The magazine inner must be adjusted depending
upon the length of fastener to be driven. To make this adjustment open the magazine
cover by pulling the latch as in figure 5. To remove the inner magazine simply
depress the two tabs together and lift as in figure 6. This figure shows the proper
placement of the magazine inner for screws longer than 1-1/2". For 1" to 1-1/2"
screws the magazine inner must be inverted and re-installed as shown in figure 7.
(d) Insertion And Removal Of The Bit - Always use a no. 2 type bit of 184mm (7-
1/4") in length. The bit type should be the same as the type of screws being driven.
For example, if the screws have a phillips head recess, then a phillips bit must be
used. If the screws have a square recess then a square bit must be used. All Muro
bits are double ended. When one bit tip becomes worn the bit can be turned over to
use the other end before replacing completely.
Inserting the bit - Depress the feeder block about 1° in the ‘A’ direction as shown in
figure 8. Pass the bit through the feeder block center hole, through the depth
adjuster dial and align with the hexagonal sleeve hole. Release feeder block. Depress
the locking sleeve in the "A" direction and slide the bit fully into the hole. Release the
focking sleeve to hold the bit in piace. Check that the bit is fully secured.
Removing the bit - Depress the locking sleeve in the 'A' direction and slide bit
forward as far as possible and out of the locking sleeve. Then depress feeder block
about 1” in the ‘À’ direction and slide the bit completely out of the tool.
NOTE: Do not attempt to remove the bit by force using pliers or other tools.
Also, to prevent any chance of injury during bit replacement, ensure the tool's
switch is off and the plug is disconnected from the power source prior to bit
replacement,
(e) Loading of VISROPE Screws Coils- Open the magazine lid and ensure that the
magazine inner is adjusted as described previously corresponding to the fastener
length to be driven. Place the VISROPE into the magazine with the screw heads
facing upwards. Pull the forward end of the VISROPE coil out of the magazine
outlet and close the magazine lid. Insert the VISROPE into the siot between the
feeder block and guide cover (see fig. 9) as far as possible. Then activate the
feeding mechanism by depressing the feeder block about 1" in the "A" direction, as
llustrated and release. The tools feed mechanism will pull the first screw
into place, which should look like figure 10.
(f) Unloading Visrope - To remove the VISROPE, shift the guide cover to the left and
tilt it upwards (see fig. 11) Push the feeder block in the 'A' direction, press the grip
finger downwards and pull the VISROPE to the left to remove the screws.
(9) Screws of Different Lengths - Screws ranging from 1" to 3" can be driven with
your tool. The plastic tape location of collated Muro VISROPE is either 22mm or
30mm down from the head of the screw. The respective position depends upon the
length of the screws being driven. Screws ranging from 1° to 1-3/4" are collated at
22mm, while the longer screws from 1-3/4" to 3" are collated at 30mm. The tool is
designed so that the plastic will always be in the same position on the feeder block.
When loading your VISROPE be sure to feed the screw head into the appropriate slot
as in figure 12.
(h) Stopper Block Adjustment - Depending upon whether 22mm or 30mm collated
screws are being driven, the stopper block needs to be adjusted accordingly. To
adjust the stopper block, loosen the cap screw under the extension block on the right
hand side of the tool. Slide the stopper block fully forward for 30mm collation or
fully backward for 22mm collation. See figure 13. CAUTION: Removing the cap
screw completely will allow the head of the tool to eject from the motor. Take care
not to remove this screw fully when making the stopper block adjustment.
(i) Screw Guide Adjustment - the distance that the screw extends onto the screw
guide should be kept at approximately 3/8". See figure 14. The screw guide is
adjusted by loosening screw 'B' on the top side of the feeder block and by sliding
the screw guide in and out to achieve the appropriate setting. The magazine will
move with the size piece so that the screws may be fed easily into the feeder bluck.
Be sure to retighten screw 'B' when the adjustment is complete.
(j) Countersink Depth Adjustment - By turning the depth adjusting dial left or right,
the depth to which screws may be driven can be adjusted. See figure 15. Rotating
the adjusting dial to the right reduces driving depth, rotating to the left increases
driving depth.
(k) Extension Handle (optional accessory) Installation - The FD/FLVL41 tool is
designed primarily to be used as a flooring and decking tool. For maximum operat-
ing comfort the too! may be fitted with the optional extension handle which allows
the operator to stand up while driving screws. The length of this handle may be
adjusted to suit the operator's height and most comfortable driving posture.
To attach the handle to the tool , place the handle into the handle bracket, as shown
in figure 1, and secure it in position by tightening the knob.

OPERATING INSTRUCTIONS
OPERATION OF THE FD/FLVL41
(a) Driving Screws - With the FD/FLVL41 loaded with the appropriate VISROPE, grasp
the tool solidly and adopt a stable posture. The optional extension handle allows the
tool to be gripped comfortably and firmly with both hands. Pressing the trigger
switch starts the motor but does not cause the bit to rotate. Ensure the tool's screw
guide is placed firmly onto the work surface. Failure to securely hold the screw guide
against the work surface may result in the screw being incompletely driven. Pushing
firmly forward on the tool will force the driver bit into the screw recess and the bit
will start to rotate and begin to drive the screw. Maintain force on the tool until the
screw is completely driven. The screw should be driven with a single action and once
the screw is fully driven, allow the feeder block to return to it's original position and
the next screw will automatically feed forward.
If the feeding mechanism should jam, stop driving immediately. Remove the
VISROPE as previously described, clear the jam, reload and restart driving.
(b) Removing Screws - Should a screw be driven incorrectly or in the wrong
location, you can use the FD/FLVL41 tool to remove screws. To do this you must first
switch off the tool motor, unload VISROPE, press reversing switch to reverse mode
place the bit tip into the recess of the screw. Push down lightly on the tool to hold
bit in the screw recess and press trigger to remove the screw.
WARNING: Whenever driving screws into surfaces which might contain hidden live
electrical wires be sure to hold the tool only by its insulated grasping surface and
not to touch any metal components of the tool which may become live. For
horizontal applications figure 16 shows the proper way to hold the tool.

MAINTENANCE AND INSPECTION
To ensure trouble-free operation of your FD/FLVL4 tool, please note the following:
(1) Inspect the driver bit and replace with a new one whenever excessive wear or
damage is noticed.
(2) To ensure that the grip finger, guide cover and guide poles slide smoothly,
regularly apply 2 - 3 drops of a high grade lubricating oil.
(3) The gap between the guide cover and the feeder block should be sufficient to
allow free movement of the VISROPE. If this gap size is incorrect, it may result
in feeding problems.
To adjust this gap, loosen the lock nut on the adjusting screw using the M4 nut
wrench supplied. See figure 17. The width of the nut wrench's handle is .210'
(5.4mm) and may be used as a guide for adjusting the gap by sliding it on edge 210" С Г
22 30
between the guide cover and feeder block. Using the 3mm allen key, turn the
adjusting screw to widen or narrow the gap. When the gap is set, tighten the lock Figure 17
210” —— > «4 — —
nut while holding the adjusting screw in position with the allen key.
(4) As vibration through use can cause screws to loosen, periodically tighten
screws on the feeder block.
(5) The motor uses carbon brushes. These should be inspected regularly and REPLACE BRUSH WHEN
replaced as necessary. See figure 18. To replace carbon brushes, remove WORN TO 3/16”
brush cap, then remove spring and brush assembly. Carbon brushes should
always be replaced in pairs. Install new brushes and replace brush cap.
(6) The tool should be maintained in good condition. For optimum performance,
clean and adjust the unit regularly. Wood chips or other materials will affect
the tool's performance and consequently it's efficiency. Remove such
materials from the feeder block before and after use.
(7) Dust in the motor should be discharged every 50 hours of operation. A
method of discharging the dust is to run the motor in a no-load situation and
blow compressed air into the housing through the front air vents causing the
dust and air to exhaust together through the rear air vents.
