LUBRICATION
STEP 1 – Thoroughly clean all three shas.
STEP 2 – Flood spray all three shas with CRC 3-36 unl the lubricant is dripping o the shas. Do not use
Then run the grinding head assemblies back and forth through their full range
of travel. This will remove the dust and deposits from inside the wheel anges. Repeat if necessary unl
lubricaon is clear of deposits. Clean keyways located on the grinding sha with so brush.
STEP 3 – With a clean rag, wipe o the excess amount of lubricant from the shas. Run the grinding
assemblies through their range of travel and wipe the shas aer each traverse. Repeat unl the shas are
dry to the feel. This completes the lubricaon process.
IMPORTANT:
If the unit will be shut down for an extended period of me, more than four weeks, then the shas and other
appropriate parts of the unit should be ooded with lubricant and that lubricant le in place unl the unit is

CLEANING AND MAINTENANCE GUIDELINES FOR POLYCARBONATE
WINDOWS
Wash polycarbonate windows with a mild dish washing liquid detergent and lukewarm water, using a clean
so sponge or a so cloth. Rinse well with clean water. Dry thoroughly with a moist cellulose sponge to
prevent water spots. Do not scrub or use brushes on these windows. Also, do not use butyl cellosolve in
direct sunlight.
Fresh paint splashes and grease can be removed easily before drying by rubbing lightly with a good grade
of VM&P naphtha or isopropyl alcohol. Aerward, a warm nal wash should be made, using a mild dish
washing liquid detergent soluon and ending with a thorough rinsing with clean water.
Scratches and minor abrasions can be minimized by using a mild automobile polish. Three such products
that tend to polish and ll scratches are Johnson paste Wax, Novus Plasc Polish #1 and #2, and Mirror Glaze
plasc polish (M.G. M10). It is suggested that a test be made on a corner of the polycarbonate window with
the product selected following the polish manufacturer's instrucons.
• DO NOT use abrasive or highly alkaline cleaners on the polycarbonate windows.
• Never scrape polycarbonate windows with squeegees, razor blades or other sharp instruments.
• Benzene, gasoline, acetone or carbon tetrachloride should be used on polycarbonate windows.
• DO NOT clean polycarbonate windows in hot sun or at elevated temperatures.
• Butyl cellosolve, (for removal of paints, marking pen inks, lipsck, etc.)
• The use of masking tape, adhesive tape or lint removal tools works well for liing o old weathered
paints.
• To remove labels, sckers, etc., the use of kerosene, VM&P naphtha or petroleum spirits is generally
eecve. When the solvent will not penetrate scker material, apply heat (hair dryer) to soen the
adhesive and promote removal.

located on the spin board as remote torque preset at 2:00 for torque seng. See FIG. 17. The (SSP) is located
on the control panel and is for spin speed adjustment.
Spin Torque Pot (STP) controls maximum torque allowable in the spin grinding cycle only. This should never
be adjusted past the 3:00 posion. If the reel does not turn, check that the reel is free turning by hand
spinning with the power OFF and the spin drive disconnected.
The Spin Speed Pot (SSP) controls reel spin speed, adjust as required. This controls the spin drive speed for
spinning the reel.
The IR Compensaon Pot is factory set at 9:00. Regulaon of the spin or relief grind spin motor
may be improved by a slight adjustment of the IR COMP Pot clockwise from its factory-set posion.
Overcompensaon causes the motor to oscillate or to increase speed when fully loaded. If you reach such a
point, turn the IR COMP Pot counterclockwise unl symptoms just disappear.
