WARNING - READ ALL INSTRUCTIONS
Disconnect the power cord from the receptacle before performing any
maintenance on this tool. Do not attempt to repair this tool unless you are a
Dixon authorized qualified electrician. When using electric tools, basic safety
precautions should always be followed to reduce the risk of fire, electric shock
and personal injury.
SECTION 1 - IMPORTANT SAFETY INSTRUCTIONS
1. Work Area:
1-1
Keep your work area clean and unobstructed.
- Cluttered and poorly lit work areas invite accidents.
1-2
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.
1-3
Keep bystanders, children, and visitors away while operating a
power tool.
- Distractions can cause you to lose control of the tool.
2. Electrical Safety:
2-1
Grounded tools must be plugged into a properly installed outlet and
grounded in accordance with all codes and ordinances. Never
remove the grounding prong or modify the plug in any way. Do not
use adaptor plugs. Check with a qualified electrician if you think the
outlet may not be properly grounded.
All non-UL listed drivers are ESD housed.
-If the tool should electrically malfunction or break down, proper
grounding provides a low resistance path to carry electricity away
from the user.
2-2
Double insulated tools are equipped with a polarized plug (one
blade is wider than the other). This plug will only fit in a polarized
outlet one way. If the plug does not fully fit in the outlet, reverse the
plug. If the plug still does not fit, contact a qualified electrician to
install a polarized outlet. Do not change the plug in any way.
2-3
Do not expose power tools to rain or wet conditions.
- Water entering a power tool will increase the risk of electric shock.
2-4
Do not operate power tools in damp or wet locations.
- Operating tools in these conditions will increase the risk of electric
shock.

2-5
Do not abuse the cord. Never use the cord to carry the tool or to
yank the tool from an outlet. Keep the cord away from heat, oil,
sharp edges, or moving parts. Immediately replace damaged cords.
- Damaged cords increase the risk of electric shock.
2-6
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.
3. Personal Safety:
3-1
Stay alert and use common sense while operating a power tool. Do
not use these tools while tired or under the influence of drugs,
alcohol, or medications.
- A moment of inattention while operating a power tool may result in
serious personal injury.
3-2
Dress properly. Do not wear loose clothing or jewelry. Tie back or
contain long hair. Keep your hair, clothing, and gloves away from
moving parts.
- Loose clothes, jewelry, or long hair can be caught in moving parts.
3-3
Avoid accidental starting. Be sure the switch is off before plugging
in the tool.
- Carrying tools, with your finger on the switch or plugging in tools
that have the switch "ON," invites accidents.
3-4
Remove adjusting keys or switches 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.
3-5
Do not overreach. Keep proper footing and balance at all times.
- Proper footing and balance enables better control of the tool in
unexpected situations.
3-6
Use safety equipment. Always wear eye protection.
- Dust masks, non-slip safety shoes, hard hats, or hearing
protection must be used when conditions warrant their use.

4. Tool Use and Care:
4-1
Use clamps or other practical ways to secure and support the work
piece to a stable platform.
- Holding the work piece by hand or against your body is unstable
and may lead to loss of control and injury.
4-2
Do not force the tool. Use the correct tool for your application.
- Operate the tool within its design parameters. The correct tool will
do the job better and safer.
4-3
Do not use the tool if the power switch does not turn the tool on or
off.
- Any tool that cannot be controlled with the switch is dangerous
and must be repaired.
4-4
Disconnect the plug from the power source before making any
adjustments, changing accessories, or storing the tool.
- These preventive safety measures reduce the risk of the tool
accidentally starting.
4-5
Store idle tools out of reach of children and other untrained
persons.
- Tools are dangerous in the hands of untrained users.
4-6
Maintain tools with care and, in accordance with, standard industrial
practices.
- Properly maintain tools.
4-7
Check for misalignment or binding of moving parts, breakage of
parts, and any other condition that may affect the tool’s operation. If
the tool has any damage, have the tool serviced before using.
- Many accidents are caused by poorly maintained tools.
4-8
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.
Page 3 of 14
5. Service:
5-1
Tool service must be performed only by qualified repair personnel.
- Service or maintenance performed by unqualified personnel could
result in a risk of injury.
5-2
When servicing a tool, use only factory provided replacement parts.
- Use of unauthorized parts or failure to follow maintenance
instructions may create a risk of electric shock or injury.

SECTION 2 - GROUNDING INSTRUCTIONS
1. The tool should be grounded while in use to protect the operator from
electric shock. Notice! To ensure proper grounding, the grounding
conductor of the power cord must be well connected to the grounding
terminal of the power facility. The tool is equipped with a three-conductor
cord and three-prong grounding-type plug to fit the proper grounding-type
receptacle. The green (or green and yellow) conductor in the cord is the
grounding wire. Never connect the green (or green and yellow) wire to a
line terminal.
Green and Yellow ----- Ground
Blue ------ Neutral
Brown ------ Line
2. Grounding of the tool is the most important precaution taken to protect
the user. Every 3-6 months use an Ohm meter to check the ground
connection. Follow these simple instructions: (a) set the Ohm meter level
to R*100 (Ohm), (b) touch the 2 testing probes ("+" & "-") together and
reset the meter to "0", and (c) use the Red ("+") probe to touch the ground
wire on the plug of tool’s cord, and the Black "-" probe to touch the end of
bit head. Grounding is normal if the meter reading is close to "0". To get a
normal indication from the meter while testing, the test probes must be
firmly pressed with both hands to the test points.
3. This tool has been tested at the factory by applying 26 amps to the
grounded metal. The ground resistance was equal to or less than 0.2
Ohms.

SECTION 3 - OPERATOR CAUTIONS
1. When changing a bit, make certain the Forward / Reverse switch is in
the "OFF" position and the tool is unplugged.
2. Do not allow chemicals such as acetone, benzene, thinner,
trichloroethylene, ketone, or other similar chemicals to come in contact
with the screwdriver housing or damage will result.
3. Do not drop or abuse the screwdriver.
4. Do not adjust the torque setting higher than 8 on the torque scale.
5. There should be a tool rest interval of three seconds or longer. This tool
is intended for a cycle of 0.8 sec on, 3.2 sec off. Do not tighten more than
15 pieces per minute. Do not allow the motor to overload or overheat.
6. Do not tighten more than 900 self-tapping screws per hour.
7. Do not switch from Forward to Reverse while the motor is running.
8. Be sure the Forward / Reverse switch is in the "OFF" position before
connecting or disconnecting the screwdriver plug.
9. Whenever the tool is not being used or when changing accessories,
move the Forward / Reverse Switch to the "OFF" position and unplug the
screwdriver.
WARNING
Do not drop or abuse the tool.
Whenever a tool is not being used,
set the Power Switch to the "OFF"
position and unplug the power cord.

SECTION 5 – BIT CHANGING AND SCREWDRIVER
OPERATION
Attaching / Detaching Bits and Types of Bits:
Push the bit holder clamp up with your finger tip, and it will unlock the bit. The bit
can be freely attached and detached (single finger motion type). Select a power
drive hex bit with a shank equal to the size shown below.
Shape of Bit:
6.35mm Hex
Basic Screwdriver Operation:
Insert the power plug into a receptacle and set the direction switch to the forward
“F” position.
For a push-to-start type screwdriver, apply the bit to the screw head and push the
main body against the bit to start the motor running. The motor is turned "OFF"
when the torque level (set by the torque adjustment) is reached or when the
screwdriver is pulled back away from the screw head.
For a lever type screwdriver, apply the bit to the screw head. Then push the lever
to start the motor running. The motor is automatically turned "OFF" when the
torque level (set by the torque adjustment) is reached or when the lever is
released.
To remove a screw, (Dis-Assembly) set the Forward / Reverse switch to the
reverse "R" position, and use the method described above for your type of
screwdriver whether push-to-start or lever type. Note the torque level may need
to be increased to remove a screw once installed at its torque level.
Page 8 of 14
SECTION 6 - TORQUE ADJUSTMENT OPERATION
The screwdriver tightens a screw until the torque level set by the torque adjusting
ring is reached. When the torque level is reached, power is automatically
removed from the motor. To adjust the screwdriver's torque, follow the procedure
outlined below:
1. Increase or decrease the torque level by rotating the torque adjusting ring by
hand. Rotating the ring clockwise to a higher number increases the torque level.
Rotating the torque adjusting ring counterclockwise to a lower number decreases
the torque level.
2. Check the new torque level with a torque meter. The torque should be
checked for each job because a number of factors affect the torque output from
one job to another. The final torque level should be set using the actual job
pieces through a series of gradual torque increases. You should always start
below the desired torque level and work upward.
3. The torque of all the 3100 series screwdrivers can be measured with our
KTM-100/A Torque Meter.
4. After using a torque meter to measure and adjust the torque of the
screwdriver, you may want to install a torque fixing ring accessory around the
torque adjusting ring. The torque fixing ring simply screws onto the housing of the
screwdriver. The torque fixing ring prevents operators from re-adjusting the
torque of the screwdriver. For further adjustments, the torque fixing ring must
first be removed.
5. Sometimes the Reverse “R” torque required to remove (Dis-Assembly) a
screw is larger than the torque that was used to tighten that screw. If the
tightened screw will not loosen easily, the clutch may skip or slip. If slipping does
occur, you must reset the screwdriver torque to a higher value to loosen the
screw.
Page 9 of 14
CAUTION
1. For reverse rotation, the clutch turns the motor off in the same manner it does
for the forward rotation. Accordingly, when a screw is tightened at a high torque,
and it cannot be backed out because the motor turns off, set the torque level to a
higher torque setting to back the screw out.
2. The numbers from zero to eight on the torque adjusting ring are reference only
numbers and not an exact indication of actual torque output.
3. The mechanical "clutch facing", or wear, of the SK series screwdrivers
depends on the torque output used on the tool, on the frequency the tool is used,
and on total usage time of the tool. The more the tool is used the more "facing"
occurs. A new tool set at a torque output level of 4 may experience a decline of
approximately 5-7% after being used for one month (a 7-10% decline may occur
if torque level is set at 8). However, the declining torque will become minor and
stabilized after about one month. To verify the torque output, the user should
check the torque output periodically with a torque meter and adjust the torque
upward 1-2 positions on the torque fixing ring scale to achieve the desired output.
To avoid arbitrary operator adjustments, the torque fixing ring accessory is
recommended when a torque adjustment is made.

SECTION 8 - SERVICING
Maintenance and Inspection:
1. The screwdriver must be operated in peak condition, and the working day
must not exceed more than eight hours.
2. Periodically check for wear of the motor's carbon brushes. If the brushes have
worn down by 2-3mm, replace them with a new brush assembly. Brush life
depends on the operation frequency and torque output. The greater the use and
higher the torque, the more rapidly the brushes will wear. Expect to replace the
brushes every 5-6 months.
3. When the total usage hours reach 1,000 hours or every 5-6 months: (a) clean
the tool's inner parts, (b) replace brushes with new brushes, (c) lubricate the gear
wheel, (d) inspect the cord assembly and armature, and (e) check if the ON/OFF
switch functions normally. This maintenance will extend the tool life and help
maintain torque accuracy.
4. Keep the motor dry and clean. Avoid the carbon build up that may decrease or
destroy the insulation.
5. Every 3-6 months lubricate the gear wheels with the recommended Magnalube
G grease. This will keep the gear assembly running smoothly and decrease the
facing of the clutch.
6. Please note - Do not let the motor get over heated. No more than 10 to 15
screws should be tightened each minute. The duty cycle for the tool is 1:4
(.8 seconds on and 3.2 seconds off).
7. Some models have an EMC box on the power cord that is equipped with a 2.5
amp fuse. The fuse will melt if the tool is supplied with high voltage by mistake, or
if there is a short caused by defects of the inner circuit or motor. The blown fuse
terminates the power supply and disables the tool.
8. Replace the fuse if it is blown. If the new fuse blows again soon after it has
been replaced, send the tool to a service center for repair.
