Troubleshooting: Mechanical and Electrical Problems

Trouble
Uneven depth of cut
side to side.
Board thickness does
not match depth of
cut scale.
Chain is jumping.
Machine will not
start/restart or
repeatedly trips
circuit breaker or
blows fuses.
Probable Cause
Knife projection from cutterhead is
incorrect (209 only)
Table not parallel to cutterhead.
Depth of cut scale is incorrect.
Inadequate tension.
Sprockets misaligned.
Sprockets are worn.
No incoming power.
Overload automatic reset has not
reset.
Planer frequently trips.
Building circuit breaker trips or fuse
blows.
Loose electrical connections.
Remedy
Adjust knife projection.
Adjust table/cutterhead parallelism.
Adjust depth of cut scale.
Adjust chain tension.
Align sprockets.
Replace sprockets.
Verify power connections to planer.
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 box.
One cause of overloading trips which
is 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.
Verify that planer is on a circuit of
correct size. If circuit size is correct,
there is probably a loose electrical
lead. Check amp settting on motor
starter.
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.
