CAUTION: Before performing any maintenance, remove the Line Cord from the electri-
cal outlet.
1.
Yoke Tightness – Periodically check and tighten the yoke Clamp Handle (66).
Over time this handle may become loose and not tighten entirely. To correct this condition,
tighten the large Nut (64) at the base of the Handle using the 5/8 inch arbor wrench.
2.
Cleaning – After each use, apply compressed air to blow clean all the parts of the Radial
Arm Saw.
3.
Saw Blades – Never use a replacement blade rated lower than 5,000 RPM, and larger
than 8 inches diameter.
4.
Motor Brushes – Inspect the two motor Brushes (55) after the first 50 hours of saw use.
After that, check every 10 hours. Replace if necessary by a qualified technician.
Improper Brush maintenance can cause motor failure. The Brush Caps (56) are located
on each side of the motor housing.
5.
Lubrication – The Radial Arm Saw does not require initial lubrication. Periodically,
however, check all moving 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 Carriage Arm bearings because they are sealed and do not
require lubrication.
6.
Motor Preventative Maintenance – In 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 improper alignment of the motor assembly, especially when
ripping
- Low current or voltage supplied to the machine
- Buildup of dust in the motor housing, which prevents proper cooling.
