Other Important Instructions for All Lexan Sheets:
•Never use abrasive or highly alkaline cleaner on Lexan polycarbonate materials.
•Never use aromatic or halogenated solvents like toluene, benzene, gasoline, acetone or carbon tetrachloride on Lexan polycarbonate materials.
•Use of incompatible cleaning materials with Lexan sheet can cause structural and/or surface damage.
•Contact with harsh solvents such as methyl ethyl ketone (MEK) or hydrochloric acid can result in surface degradation and possible crazing of Lexan sheet.
•Never scrub with brushes, steel wool or other abrasive materials.
•Never use squeegees, razor blades or other sharp instruments to remove deposits or spots.
•Do not clean Lexan polycarbonate in direct sunlight or at high temperatures as this can lead to staining.
•For all mentioned chemicals consult the manufacturer's material safety data sheet (MSDS) for proper safety precautions.

PROPER TORQUE FOR FASTENERS
The chart lists the correct tightening torque for fasteners. When bolts are to be tightened or replaced, refer to this chart to determine the grade of bolts and the proper torque except when specific torque values are assigned in manual text.
RECOMMENDED TORQUE IN FOOT POUNDS UNLESS OTHERWISE STATED IN THE MANUAL*
NOTE: These values apply to fasteners as received from supplier, dry or when lubricated with normal engine oil. They do not apply if special graphitic or molydisulphide greases or other extreme pressure lubricants are used. This applies to both UNF fine and UNC coarse threads.
