2. Two brushes are located under plastic caps on opposite sides of the
lower part of the motor. Unscrew the plastic caps and slide the brushes
out. Replace brushes when they are worn down to 3/16" (0.48 cm) in
length.

not adjustable.
4. To align a pulley, loosen the motor pulley set screws, slide the pulley
up or down into alignment then securely tighten the motor pulley set

Washing: Clean with a solution of mild soap or detergent and lukewarm
water. Use a clean soft cloth, applying only light pressure. Rinse with clean
water and blot dry with a damp cloth or chamois.
Grease, oil, or tar may be removed with a good grade of hexane, aliphatic
naphtha, or kerosene. These solvents may be obtained at a paint or
hardware store and should be used in accordance with manufacturer's
recommendations.
Caution Do not use window cleaning sprays, kitchen scouring compounds
or solvents such as acetone, gasoline, benzene, alcohol, carbon
tetrachloride, or lacquer thinner. These can scratch the sheet's surface
and/or weaken the sheet causing small surface cracks called "crazing."
Dusting: Remove dust with a soft, damp cloth or chamois. Avoid dry or
gritty cloths as they may cause surface scratches and create a static electric
charge on the surface causing dust to cling to the lid.
Polishing: Protect the lid and maintain its surface gloss by occasional
polishing with a good plastic cleaner and polish. Apply a thin, even coat
with a soft clean cloth and polish slightly with cotton flannel. Then wipe
with a damp cloth to help eliminate electrostatic charges that can attract
dust particles.
Use of proper cleaning agents: When selecting a cleaning or
decontamination agent, use the following table as a guideline.
