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 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.
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.
