Snorkel TB126J - Manual (Page 52)

8. EMERGENCY OPERATION
8 - 5 P/N 0191915
D A N G E R
Death or serious injury can result from being
crushed by the main boom as it lowers. At the
next step do not reach for the manual bleed-
down valve from above the turntable.
Death or serious injury can result if a TB126J
tips over. A TB126J can tip over if the booms
lower without retracting. At the next step,
stop immediately if the booms lower without
retracting.
If you have any control over turntable swing,
align the turntable with the chassis to take
advantage of the extended base of support.
2. Reach the manual bleed-down valve from the
position shown above.
3. Very slowly open the bleed-down valve. The
further it is opened, the faster the booms come
down
D A N G E R
Be certain you close the emergency bleed-
down valve at the next step. Failure to do so
prevents the main boom from remaining
stationary in an elevated position.
4. Close the emergency bleed-down valve when
the main boom is horizontal.
