MAINTENANCE
CAUTION: Before performing any main-
tenance, remove the Line Cord
from the electrical outlet.
Yoke Tightness – Periodically check 1.
and tighten the yoke Clamp Handle
(66).
Over time this handle may become
loose and not tighten entirely. To cor-
rect this condition, tighten the large
Nut (64) at the base of the Handle
using the 5/8” arbor wrench.
Cleaning – After each use, apply 2.
compressed air to blow clean all the
parts of the Radial Arm Saw.
Saw Blades – Do not use a replace-3.
ment blade rated lower than 5,000
RPM, and larger than 8-1/4” diam-
eter.
Motor Brushes – Inspect the two 4.
motor Brushes (55) after the rst 50
hours of saw use. After that, check
every 10 hours. Replace if necessary
by a qualied technician.
Improper Brush maintenance can
cause motor failure. The Brush Caps
(56) are located on each side of the
motor housing.
Lubrication – The Radial Arm Saw 5.
does not require initial lubrication.
Periodically, however, check all mov-
ing parts (i.e., knobs, levers, column
shaft, Elevating Handle, shafts) to
make sure that they move smoothly.
If lubrication is required, use a small
amount of light oil. Do not oil the Car-
riage Arm bearings because they are
sealed and do not require lubrication.
Motor Preventative Maintenance – In 6.
addition to worn motor Brushes, the
following are major causes of motor
failure:
Using a dull or sticking Saw Blade•
Feeding the stock through the Saw •
Blade too fast
Starting the cut before the Saw •
Blade has reached full speed
Abnormal friction caused by improp-•
er alignment of the motor assembly,
especially when ripping
Low voltage supplied to the machine•
Buildup of dust in the motor housing, •
which prevents proper cooling.
