IMPORTANT: • Before installing, clean the bolt and nut threads to remove soil, rust, and/or dust.
• When installing new bolts and/or nuts, apply lubricant (e.g. white zinc B dissolved into spindle oil)
to the screw threads.
• Tighten bolts and nuts to the specifications. If tightened with excessively high or inadequate
torque, missing or breakage of bolts and/or nut may result.
• In case the counterweight mounting bolts became loose, consult your authorized dealer for
retightening.
