toward the operator. Make sure the riving knife
is aligned properly with the blade.
Electrical Requirements
•
Pay particular attention to the connection be-
tween your power equipment and your power
source. Before you plug in your Mark V, check
the voltage and the amperage of the circuit you
will be using. The wall receptacle and wires in
the circuit must be rated for at least 15 amps.
Circuit
•
The Mark V 115-volt motor is rated at 1-1/8 hp.
It develops more than 1-1/2 hp in use and
"pulls" 13-14 amps when running under a heavy
load. The headstock motor runs on standard
U.S. house current– 120 volts, 60 hz. The wire
size (gauge) in the circuit you use must be rated
for at least 15 amps. Using wire and receptacles
rated to handle 20 or 25 amps will give you an
even bigger safety margin.
Fuses
•
We recommend you install circuit breakers or
fuses which are time-delayed. Fusetron T-15
fuses are recommended.
Do not use fuses or
circuit breakers larger than 15 amps.
When
you first turn on the machine, the motor pulls
high amperage to get up to running speed. A
time delay fuse or circuit breaker won't blow
during this initial surge. Always start the Mark
V at "Slow" speed setting to prevent blowing
fuses and tripping the circuit breaker.
•
If you need to run a new circuit to operate the
Mark V, be sure that the wire and receptacle you
use is rated to handle the amperage of the head-
stock motor, and is at least 15 amps.
Grounding
•
The circuit you see should be properly grounded.
Extension Cords
•
If you use an extension cord to plug in your
Mark V, be sure it is a three-conductor cord with
a grounding plug and receptacle.
•
The wire gauge must be thick enough to prevent
loss of power and overheating– the longer the
cord, the thicker the wire should be. Use the
chart to determine the American Wire Gauge
wire size required:

•
Before using an extension cord, inspect it for
loose wires or damage insulation.
Replace dam-
aged cords immediately.
•
Do not let the connection between the power
cord and an extension cord lie on a damp or wet
surface.
Shopsmith Safety Kit
WARNING
DO NOT TRY TO MAINTAIN OR REPAIR YOUR
PUSH BLOCKS, PUSH STICKS, FENCE STRAD-
DLERS, OR FEATHER BOARDS. WORN OR
VISUALLY DEFECTIVE SAFETY EQUIPMENT
NEEDS TO BE REPLACED IMMEDIATELY.
•
These safety devices are designed to hold or
maneuver stock close to moving blades, cutters
and discs. They give you better control over the
stock which helps achieve a more accurate cut.
Depending on the operation, use one or more
safety devices. Choose the device that gives you
the most control and keeps your hands out of
danger.
•
Use a push stick to guide stock 1-1/2" to 5" wide.
Place the foot on top of the stock and hook the
heel over the back edge.
•
Use the push block to hold down and guide
stock over 5" wide. As you press down, for-
ward, and to the side, the rubber pad grips the
wood. The handle is tilted to help keep your
hands away from the blade, cutter or disc.
•
Use the fence straddler to hold down and push
stock narrower than 1-1/2" past a blade or cut-
ter. The body rides on the rip fence, while the
heel hooks over the back edge of the stock. To
change the height of the heel, loosen the locking
knob. To reverse the heel, rotate the side 180°.
Keep the locking knob secure.
•
Use the feather board to press stock against the
