Safety Warnings and Precautions
WARNING: When using tool, basic safety precautions should always be followed to
reduce the risk of personal injury and damage to equipment.
Read all instructions before using this tool!
1.
Keep work area clean. Cluttered areas invite injuries.
2.
Observe work area conditions. Do not use machines or power tools in damp or wet
locations. Don’t expose to rain. Keep work area well lighted. Do not use electrically
powered tools in the presence of flammable gases or liquids.
3.
Keep children away. Children must never be allowed in the work area. Do not let them
handle machines, tools, or extension cords.
4.
Store idle equipment. When not in use, tools must be stored in a dry location to inhibit
rust. Always lock up tools and keep out of reach of children.
5.
Use the right product for the job. Do not attempt to force a small product or attachment to do the work of a larger industrial tool. There are certain applications for which
this product was designed. It will do the job better and more safely at the rate for which
it was intended. Do not modify this product and do not use this product for a purpose for
which it was not intended.

SKU 03914
For technical questions, please call 1-800-444-3353.
Page 6.
Dress properly. Do not wear loose clothing or jewelry as they can be caught in moving
parts. Protective, electrically nonconductive clothes and nonskid footwear are recommended when working. Wear restrictive hair covering to contain long hair.
7.
Do not overreach. Keep proper footing and balance at all times. Do not reach over or
across running machines.
8.
Maintain tools with care. Keep needles sharp and tools clean for better and safer
performance. Follow instructions for lubricating and changing accessories. Inspect tool
cords periodically and, if damaged, have them repaired by a qualified technician. The
handles must be kept clean, dry, and free from oil and grease at all times.
9.
Disconnect power. Always turn the machine off and, if possible, disconnect the power
plug of the machine from the receptacle before adjusting, repairing, or cleaning the
machine; leaving the machine unattended; tilting the machine head; or removing the
V-belt.
10. Remove adjusting keys and wrenches. Check that keys and adjusting wrenches are
removed from the machine work surface before plugging it in.
11. Avoid unintentional starting. Be sure the switch is in the Off position when not in use
and before plugging in.
12. Stay alert. Watch what you are doing, use common sense. Do not operate when you
are tired.
13. Check for damaged parts. Before using any product, any part that appears damaged
should be carefully checked to determine that it will operate properly and perform its
intended function. Check for alignment and binding of moving parts; any broken parts
or mounting fixtures; and any other condition that may affect proper operation. Any part
that is damaged should be properly repaired or replaced by a qualified technician. Do
not use if any switch does not turn On and Off properly.
14. Guard against electric shock. Prevent body contact with grounded surfaces such as
pipes, radiators, ranges, and refrigerator enclosures.
15. Replacement parts and accessories. When servicing, use only identical replacement
parts. Use of any other parts will void the warranty. Only use accessories intended for
use with this tool. Approved accessories are available from Harbor Freight Tools.
16. Do not operate tool if under the influence of alcohol or drugs. Read warning labels
if taking prescription medicine to determine if your judgment or reflexes are impaired
while taking drugs. If there is any doubt, do not operate the tool.
17. Use proper size and type extension cord. If an extension cord is required, it must be
of the proper size and type to supply the correct current to the tool without heating up.
Otherwise, the extension cord could melt and catch fire, or cause electrical damage to
the tool. This tool requires use of an extension cord with up to 10 amps capability (up to
50 feet), with wire size rated at 18 AWG. Longer extension cords require larger size wire.
If you are using the tool outdoors, use an extension cord rated for outdoor use (signified
by “WA” on the jacket).
20. Maintenance. For your safety, service and maintenance should be performed regularly
by a qualified technician.
21. Pacemaker safety warning. People with pacemakers should consult with their
SKU 03914
For technical questions, please call 1-800-444-3353.
Page physician(s) before using this product; operation of electrical equipment in close proximity to a heart pacemaker could cause interference to or failure of the pacemaker.
Note: Performance of this tool may vary depending on variations in local line voltage. Extension cord usage may also affect tool performance.
Warning: The warnings, cautions, and instructions discussed in this instruction manual
cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be built
into this product, but must be supplied by the operator.

tightness, move the Feed Eccentric Cam down (counterclockwise).
Adjusting the Height of the Feed Dog
The Feed Dog is factory adjusted so that it juts
out from the Throat Plate surface 0.8 mm to 0.9
mm. If the Feed Dog juts out too much, puckering may result when sewing lightweight materials. To adjust the height of the Feed Dog:
1.
Loosen Screw (2) of Crank (1).
2.
Move the Feed Bar up or down to make
the adjustment.
3.
Tighten Screw (2), being careful not to
overtighten.
Adjusting Needle-to-hook Timing

marker line “B” on the needle bar (2) with
the bottom end of the needle bar lower
bushing (3), then tighten Set Screw (1).
4.
When using a DBX1 needle, loosen three
Hook Set Screws, turn the Hand Wheel,
and align the marker line “B” on the needle
bar (2) with the bottom end of the needle bar lower bushing (3).
When using a DAX1 needle, align the marker line “D” on the needle bar (2) with the
bottom end of the needle bar lower bushing (3).
5.

center of the needle (4).
Provide a clearance of .001” to .004” (0.04 to 0.1 mm) between the needle and the
hook. This clearance is less than 1/64” (almost touching). Securely tighten the three
Set Screws. If the clearance is too small, the tip of the hook will be abraded. If it is too
large, it will lead to skip over.

special or consequential damages arising from the use of our product. Some states do not allow the exclusion or
limitation of incidental or consequential damages, so the above limitation of exclusion may not apply to you. This
warranty is expressly in lieu of all other warranties, express or implied, including
the warranties of merchantability and fitness.
To take advantage of this warranty, the product or part must be returned to us with transportation charges prepaid.
Proof of purchase date and an explanation of the complaint must accompany the merchandise. If our inspection
verifies the defect, we will either repair or replace the product at our election or we may elect to refund the purchase
price if we cannot readily and quickly provide you with a replacement. We will return repaired products at our
expense, but if we determine there is no defect, or that the defect resulted from causes not within the scope of
our warranty, then you must bear the cost of returning the product.
This warranty gives you specific legal rights and you may also have other rights which vary from state to state.
