2. Door Latch Adjustment
Normaloperationofthetongmaycausewearofthedoorlatch,whichwillcausethedoortodevelopaloosefitatthelatch.A
latchcamplateislocatedatthetopfaceofthedoor.Thecamplatehaseightpositioningholeslocatedona360degreebolt
circle.Thelatchcamshaftextendsdownthroughthedoorandissecuredatthetopbya3/8”hexheadbolt.Tomakeadjust-
mentsindooralignment,removethe3/8”boltandturnthecamwithawrench.Whenthedoorhasbeenadequatelyaligned,
replacethe3/8”bolt(seeillustrationnextpage).
THE DOOR IS AN IMPORTANT PART OF THE STRUCTURAL INTEGRITY OF THE TONG. IT IS
IMPERATIVE TO KEEP A SECURE FIT AT THE DOOR IN ORDER TO MAINTAIN PROPER GEAR
ALIGNMENT, AND TO MINIMIZE THE POSSIBILITY OF DAMAGE TO THE GEAR TRAIN WHEN
OPERATING THE TONG AT SPECIFIED TORQUE. A CLOSED DOOR ALSO ENSURES SAFETY OF
OPERATING PERSONNEL.
