REMEDY
If the motor makes a humming noise
but does not start the capacitor may
have failed. Replace the capacitor.
Check motor turns freely, remove the
black fan cover. It should be possible
to turn the fan with slight pressure
from one finger. If not check for
obstructions of the fan.
Loosen each of the 6 bolts on the
back of the pump by ¼ of a turn and
check if the motor turns freely.
Remove the 6 bolts from the pump
and separate the motor and pump.
Check the gears for any silicone
sealant or other material. When
reassembling, the torque for the bolts
is 12 ft lb, 16 N m.
Check underneath the blade/pusher
and down the sides of the carriage,
for any splinters of wood that may be
obstructing the carriage.
Also check that the plastic spacers
underneath the blade and between
the carriage and the underside of the
splitter have not been dislodged.
Check the log bed for a build up of
sap. Clean the bed and apply a thin
layer of grease to the bed.
Use the Ramstop to lock the ram
in position about 150mm forward.
Remove the 4 bolts holding the
Duocut blade/pusher to the carriage
and remove the blade/pusher. Unlock
the Ramstop, if the carriage returns
then the arms are bent.
Check the amount of bend with a
straight edge, if it is less than 5mm
then you may be able to straighten
them in a vice.
If the ram does not return after
removing the Duocut blade. Loosen
the 2 rear lock nuts on the carriage
arms and remove the 2 nuts in
front of the crosspiece. Remove the
carriage from the log splitter. If the
ram does not return contact the
dealer.
