6.7 Check and Replace Fasteners
Timberwolf recommend that any nuts or bolts which are disturbed during the course of
operation or maintenance should be inspected by the operator for signs of wear or stress. If
any doubt exists over the serviceability of the fasteners then they should be replaced with
new items to the same specification. Use only Timberwolf fasteners, as they are of a higher
grade. Failure to use the appropriate grade may result in damage, injury or death.
The Timberwolf TW 280PHB is subject to large vibrations during the normal course of
operation.
All fasteners must be periodically checked to ensure they have not worked loose. They
should be tightened to the correct torque, using a calibrated torque wrench. (Refer to Table
5.)
An uncalibrated torque wrench may be inaccurate by as much as 25% and result in
fasteners being either too loose, or overtightened.
