Troubleshooting: Mechanical & Electrical Problems
Trouble Probable
Cause
Remedy
Board thickness does
not match digital
display
Digital display not calibrated properly.
Follow calibration procedures.
Inadequate chain tension.
Adjust chain tension.
Sprockets misaligned.
Align sprockets.
Chain jumping
Sprockets worn.
Replace sprockets.
No incoming power.
Verify unit is connected to power, and
main switch is set to “I”.
Overload automatic reset has not
reset.
When planer overloads on the circuit
breaker built into the motor starter, it
takes time for the machine to cool
down before restart. Allow unit to
adequately cool before attempting
restart. If problem persists, check
amp setting on the motor starter
inside the electrical enclosure.
Planer frequently trips.
One cause of overloading trips which
are not electrical in nature is too
heavy a cut. The solution is to take a
lighter cut. If too deep a cut is not the
problem, then check the amp setting
on the overload relay. Match the full
load amps on the motor as noted on
the motor plate. If amp setting is
correct then there is probably a loose
electrical lead. Check amp setting on
motor starter.
Building circuit breaker trips or fuse
blows.
Verify that planer is on a circuit of
correct size. If circuit size is correct,
there is probably a loose electrical
lead. Check amp setting on motor
starter.
Loose electrical connections.
Go through all the electrical
connections on the planer including
motor connections, verifying the
tightness of each. Look for any signs
of electrical arcing which is a sure
indicator of loose connections or
circuit overload.
Machine will not
start/restart or
repeatedly trips
circuit breaker or
blows fuses.
Motor starter failure.
Examine motor starter for burned or
failed components. If damage is
found, replace motor starter. If motor
starter looks okay but is still suspect,
you have two options: Have a
qualified electrician test the motor
starter for function, or purchase a new
starter and establish if that was the
problem on changeout. (continued)
