WARNING
Maintain proper torque to provide safe and secure
attachment of the wheel hub/drum. Improperly tightened
wheel nuts can cause the wheel to separate from the wheel mounting surface
during operation. This could result in property damage, serious personal injury,
or possibly loss of life.
NOTE
- If wheel does not have chamfers to match profile of the nuts, use flat side of
nuts against rim face.
Install all lug nuts/bolts by hand to prevent cross threading and tighten lug nuts/bolts
following the steps and tightening sequence diagram below.
NOTE
- Recheck the torque settings of lug nuts/bolts after 10km (6 miles) and again
after 50km (30 miles). Periodically and at the beginning of each season check the
condition and the torque of the lug nuts/bolts.
