RETIGHTENING OF BOLT JOINTS, TORQUE
In order to choice exactly the correct torque, information
about the friction conditions is required.
WARNING
It is important that the torque of the bolt joints
is regularly checked.
It is in particularly important that all bolts are
checked at the "first service".
WARNING
The torque of the wheel nuts must be checked
daily for the first 14 days, or until the wheels,
clamps and nuts have been tightened and no
further retightening is possible. This must be done:
• after new delivery of a machine
• after first use of the machine
• after the removal or replacement of a wheel
The bolt joints described on the following pages are to be tightened
with a torque wrench.
The chart below states the torque for bolts "slightly lubricated".
