CAUTION: If fixing bolts for counterweight are
loosened, consult your nearest authorized dealer.
IMPORTANT:
Apply lubricant (e. g. white zinc B solved into spindle
oil) to bolts and nuts to stabilize their friction
coefficient.
Remove soil, dust, and/or dirt from the nut and bolt
thread surfaces before tightening.
Tighten nuts and bolts to specifications. If tightened
with excessively low or high torque, missing or
breakage of nuts and/or bolts may result.
