DO NOT ADJUST GAPS WITHOUT
CONSULTING FACTORY. Gap settings can only
be verified after residual load against spring plate has
been neutralized. This can be accomplished by
draining the tank and removing any impediments or
if draining is not possible, then by removing motor
and rotating the input shaft of the primary reducer,
releasing tension on drive chain. Continue to rotate
input shaft until final gear starts to move opposite of
normal rotation. Stop. Further rotation of input shaft
will cause damage. Gap settings are indicated on the
inside of the torque overload housing cover or on the
General Arrangement Specification Drawing.
WARNING: DO NOT OPERATE DRIVE IN THE
REVERSE ROTATION. Torque overload switches
are NOT operative during reverse rotation. Severe
damage can occur to mechanism's structure and drive
unit. Use reversing switch, if furnished, only for
momentary jog to dislodge the rake arm from
hang-up or to unload the drive unit.
DRIVE CHAIN
SPROCKETS
Check for loose bolts, setscrews or keys. If necessary,
retorque to the correct torque value. Check teeth for
wear. Replace when tooth wear presents an
observable hooked profile.

DRIVE CHAIN
Check chain for excessive slack. Shift primary gear
reducer or remove link when required. Check
sprocket alignment by placing a straight edge across
the machined surfaces of the sprockets. Check chain
for wear.
