NOTE:
When the machine is not in use, the machine
should be locked in the “OFF” position to prevent
unauthorized use.
• To lock the machine, turn the switch to the “OFF”
position.
Pull the key out. The switch cannot be turned on without
the key.
• If the key is removed when the switch is at the "ON"
position, the switch can be turned off but cannot be
turned on again.
• To unlock, place the key into the slot on switch unit until
it snaps.
CIRCUIT BREAKER
Refer to Figure 8
• This machine has a circuit breaker installed next to the
main power switch. The circuit breaker protects the
motor unit by shutting off the power supply when
excessive electric current is detected. If the circuit
breaker is tripped, the machine will not power on.
• Before resetting the circuit breaker, check motor, switch,
and line connection for short circuit or faulty
components.
• To reset the circuit breaker, Turn the switch to "OFF"
position. Then press the circuit breaker reset button next
to the main switch.
BEFORE OPERATING THE PLANER
• Understand the machine function and observe all the
safety measurement.
• In general, the desired depth-of-cut and final thickness
of workpiece are determined before planing. Since
there is limit of maximum depth-of-cut, the workpiece
may have to pass the machine several times before
reach the desired final thickness.
• The rollercase has to be lowered manually before each
pass, if more than one pass is necessary.
• The planer machine setting involves readings of
elevation scale and operation of the rollercase elevation
crank handle.
• The rollercase elevation crank handle controls
rollercase position in height and determines the amount
of wood material to be removed (depth-of-cut) in each
pass. Thickness of the remaining workpiece, after
planing (final thickness), is observed in elevation scale.
• In general, thin depth-of-cut produces better outcome:
smooth surface, even thickness, less kickback, less
snipe, even thickness, less wear on cutterhead and
motor.
• Set thin depth-of-cut for hardwood, wide workpiece, and
uneven surface.
• This planer machine is designed to process natural
wood material only.
• Remove glue and any foreign objects from the
workpiece before planing.
• Avoid wood stock with many or large knots.
• Avoid wood stock with excessive twisting, cupping, or
bowing.
• If necessary, process one side with jointer machine first
to obtain at least one flat surface before using the planer
machine.
• For better outcome, plane both sides of wood board with
½ of depth removed from each side. This will produce
two smooth surfaces with equal amount of moisture
content. The board is less likely to warp when it dries
naturally.
• Test cut with similar wood material for better accuracy.
• The Minimal length of workpiece that can be processed
is 15”. The minimal width is
¾ ”. The minimal thickness is
1/8”. (This is not to be confused with depth-of-cut.)
• The maximal width of workpiece that can be processed
is 12 1/2”. The maximal thickness is 6”.
• To protect long use life of motor and cutterhead unit, the
recommended maximum depth-of-cut are:
3/32” for workpiece up to 5” wide
1/16” for workpiece from 5” to 12 1/2” wide
• Use additional roller stand for workpiece longer than 24”.
