Action
CAUTION
The delta unit will become unstable when a lower
arm is removed.
Support the weight of the delta unit before remov-
ing the arm to minimize the movement. Either
support the weight from underneath or secure the
weight with a lashing strap through the universal
joints closest to the telescopic shaft.
Loosen the both lower arm shafts from the upper
arm by loosening the bolts.
Use an interchangeable head torque wrench and
the open-end head insert.
Disconnect the lower arms from the upper arm.
