Troubleshooting
Remedy
The movement of each gearbox is
controlled by "stops" to provide
the correct relationship of the con-
trol arm movement to machine
movement. Excessive pressure
on control arms in any direction
does not improve reaction time
and can damage steering controls
causing machine to wobble.
Replace trowel arm(s).
Replace trowel blade(s).
Replace main shafts(s).
Replace bushings and lubricate at
least every 20 hours.
Reset control arm lever.
Replace lower control arm(s). Use
lifting brackets and/or forklift
pockets provided on machine for
lifting.
Replace drive belt.
Change pitch on blades to break
suction.
Replace damaged key.
Check all keys in drive system.
Replace damaged blades. Align
blades so that one set represents
a (+) and the other an (x) when
viewed from above.
Check all keys in drive system.
Tighten clutch.
