PERIODICALLY LUBRICATE THESE POINTS
Use SAE No. 10W-30 automotive engine oil. Refer to the
Parts Lists for locations, and lightly lubricate the following
points:
1. The rea_ bearing surface of the elevation crank shaft
assembly - and also the two meshed gears through
which this shaft drives the elevation shaft assembly.
There is an oil hole in the bracket at the rear end of the
etevatior, crank shaft, through which the rear bearing
surface can be oiled.
2. The threads of the elevation shaft assembly -- and also
the bottom bearing surface of this shaft where it is held
by the retaining plate. Use the oil hole at the center of
the radial-arm cap.
3. The bevel-latch pin.
4. The bearing surface of the swivel-latch pin in the
latch-pin housing.
5. The face of the column tube and keyway (by wiping
with a lightly oiled cloth) to lubricate the surfaces that
bear against the key and the column support assembly,
I CAUTION: Excessive oil at any location will I
!
attract airborne dust particles and sawdust.

TROUBLE SHOOTING CHART--MOTOR
NOTE: Motors used on wood-working tools are particularly and *-hould be blown out or "vacuumed" frequently to
susceptible _o the accumulation of sawdust and wood chips prevent interference with normal motor ventilation.
TROUBLE
Motor will not run.
Motor will not run and
fuses "BLOW".
Motor fails to develop
full power. (Power output
of motor decreases rapidly
with decrease in voltage at
motor terminals. For
example: a reduction of
10% in voltage causes a
reductior_ of 19% in
maximum power output
of which the motor is
capable, while a reduction
of 20% in voltage causes
reduction of 36% in
maximum power output.)
PROBABLE CAUSE
1. Protector open; circuit
broken.
2. Low voltage.
1. Short circuit in line, cord
or plug.
2. Short circuit in motor or
loose connections.
1. Power line overloaded with
lights, appliances and other
motors.
2. Undersize wires or circuit
too long.
3. General overloading of
power company's facitities.
(In many sections of the
country, demand for
electrical power exceeds
the capacity of existing gen-
erating and distribution
systems.)
4. h_correct fuses in power line.
REMEDY
1. Reset protector by pushing on red button, located
on top of motor (indicated by audible click).
2. Check power line for proper voltage.
1. Inspect line, cord and plug for damaged insulation
and shorted wires.
2. Inspect all terminals in motor for loose or shorted
terminals or worn insulation on wires.
1. Reduce the line load.
2. Increase wire sizes, or reduce length of wiring
3. Request a voltage check from the power company.
4. Install correct fuses.
