Maintenance
CAUTION: Before performing any main- tenance, remove the Line Cord from the electrical outlet.
1.Yoke Tightness – Periodically check and tighten the yoke Clamp Handle
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.
2.Cleaning – After each use, apply compressed air to blow clean all the parts of the Radial Arm Saw.
3.Saw Blades – Do not use a replace- ment blade rated lower than 5,000 RPM, and larger than
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 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.
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 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.
