Lubrication

Ball Bearings

All the motor bearings in this tool are lubri- cated with a sufficient amount of high grade lubricant for the life of the unit, therefore, no further lubrication is required.

1.Apply automotive type oil directly on slide tubes. It will be picked up and dis- persed by built in felt wicks.

2.Apply a light oil or a pressurized light spray oil to the arm pivot shaft.

3.Apply a light oil or a pressurized light spray oil to the torsion spring as shown.

4.Apply a light oil or a pressurized light spray oil to the lower guard spacer, roller and cover plate as shown.

Motor Belt Tension

The motor belt tension was properly adjusted at the factory. However, to check the belt tension:

1.Use a Phillips screwdriver to remove the five screws holding the belt cover and remove the cover.

2.To check the belt tension squeeze the belt. Using light pressure the belt should deflect approximately 1/4".

3.To adjust the tension:

a.Use a Phillips screwdriver to loosen (but do not remove) the six motor mount screws.

b.To increase the belt tension turn the adjusting socket head set screw clockwise. To decrease the tension turn the adjusting set screw counter- clockwise.

NOTE: Excessive belt tension will cause the motor to fail prematurely.

c.Securely tighten the six motor mount screws.

4.Replace the belt cover.
