7. WARNING: Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities, contain 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
and cement or other masonry products, arsenic and chromium from chemically
treated lumber. Your risk from these exposures varies, depending on how often
you do this type of work. To reduce your exposure to these chemicals: work in a
well ventilated area, and work with approved safety equipment, such as those
dust masks that are specially designed to filter out microscopic particles.
(California Health & Safety Code 25249.5, et seq.)
8. WARNING: People with pacemakers should consult their physician(s) before
using this product. Operation of electrical equipment in close proximity to a heart
pacemaker could cause interference or failure of the pacemaker.

BASIC POWER MACHINE TOOL OPERATION TIPS
1. Keep all safety guards in place, in proper adjustment, and in proper alignment.
2. Make sure the On/Off Power Switch (located on the Electrical Cord) is in the “OFF” position
before plugging the 12 Volt Transformer (part #58) into a grounded, 3-hole, 120 Volt, electrical
outlet.
3. Prior to starting a power machine tool, make sure all adjusting keys and wrenches are removed
from the tool.
4. Always keep a firm grip on the tool with both hands, and whenever possible secure the
workpiece with a vise or clamps (not included).
5. Always feed the Turning Gouge (part #49) into and against the rotational direction of the
woodstock.
6. Never leave a power machine tool unattended when it is running. Turn off the tool, and wait until
it has completely stopped before leaving.
7. Always unplug a power machine tool from its electrical supply source before performing any
inspection, maintenance, or cleaning procedures.
WOODWORKING LATHE OPERATING INSTRUCTIONS
1. On both ends of the woodstock workpiece (not included), locate and mark the center, using the
Center Finder (part #30). (See Assy. Diagram.)
2. Align the marked center of one end of the woodstock with the Drive Center (part #31), and align
the marked center of the other end of the woodstock with the Live Center (part #28).
(See Figure E.)
3. Turn the Handle on the Tailstock (part #7) clockwise until the woodstock is held firmly in place.
(See Figure E.)
4. Turn the Handle of the Large Slide (part #9) clockwise, or counterclockwise, to move the Large
Slide horizontally to the desired position in front of the woodstock. (See Figure E.)
5. Connect the Power Cord of the High Speed Motor Unit (part #4-A) to the 12 Volt Transformer
(part #58). Plug the 12 Volt Transformer into a grounded, 120 volt electrical outlet. Then, turn the
Power Switch to its “ON” position. (See Figure A.)
6. Wait until the Woodworking Lathe is turning the woodstock at full speed. Grasp the Turning
Gouge (part #49) firmly with both hands. Rest the Turning Gouge firmly on the Wood Turning
Support (part #18). (See Figure E.)
7. Slowly and carefully, move the cutting tip of the Turning Gouge (part #49) forward into the revolv-
ing woodstock, steadily applying forward pressure to make the desired depth of cut.
8. To make a cut in a different location on the woodstock pull the Turning Gouge (part #49) away
from the woodstock, and turn the Handle of the Large Slide (part #9) clockwise or counterclock-
wise to reposition the Large Slide. (See Figure E.)

INSPECTION, MAINTENANCE, AND CLEANING
1. CAUTION: Always unplug the 12 Volt Transformer (part #58) from its 120 volt electrical outlet
before performing any inspection, maintenance, or cleaning.
2. BEFORE EACH USE, inspect the general condition of the Multi-Purpose
Machine. Check for loose screws, misalignment or binding of moving parts, cracked or broken
parts, damaged electrical wiring, and any other condition that may affect its safe operation. If
abnormal noise or vibration occurs, have the problem corrected before further use. Do not use
damaged equipment.
3. DAILY: With a soft brush, cloth, or vacuum, remove all debris from the
Multi-Purpose Machine. Then, use a premium quality, lightweight machine oil to lubricate all
moving parts.
9. Continue cutting the woodstock until the job is finished. Then turn the Power Switch to its “OFF”
position, and unplug the Woodworking Lathe from its electricl outlet.
10. Wait until the woodstock has completely stopped revolving before removing it from the Wood-
working Lathe.
