6 Troubleshooting
6.1 Troubleshooting the Machine
Problem Reason Remedy
Machine out of balance; wobbling
excessively. Operator is over-steering. 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.
Trowel arm(s) bent. Replace trowel arm(s).
Trowel blade(s) bent. Replace trowel blade(s).
Main shaft(s) bent due to machine
being dropped. Replace main shafts(s).
Poor handling; excessive range in
control lever movement. Worn bushings due to lack of
lubrication. Replace bushings and lubricate at
least every 20 hours.
Control arm lever adjustment has
moved or control arm has been
bent. Reset control arm lever.
Lower control arm(s) bent. This
can be caused by dropping
machine. Replace lower control arm(s). Use
lifting brackets and/or forklift
pockets provided on machine for
lifting.
Machine does not move. Drive belt broken. Replace drive belt.
Vacuum between bottom of
blades and surface of concrete. Change pitch on blades to break
suction.
Key sheared in the main shaft. Replace damaged key.
Machine does not respond cor-
rectly to control lever movement. Sheared key. Check all keys in drive system.
Trowel noisy. Trowel blades have become mis-
aligned and are contacting each
other during rotation. Replace damaged blades. Align
blades so that one set represents
a (+) and the other an (x) when
viewed from above.
Sheared key. Check all keys in drive system.
Loose clutch. Tighten clutch.
