Caution
During certain applications, it may be necessary to plane against the
grain. This application requires that the operator use a shallow depth
of cut and a slower feed rate.
Caution
If you are inexperienced at jointing, use scrap pieces of lumber to
become familiar with the machine and its operation before doing
normal work.
WaRninG
Do not operate this machine with the safety guard removed.
Before starting the machine, inspect the machine to ensure it is free
of all debris.
Inspect area around cutterhead to ensure the cutterhead is free of
debris.
Never start the machine with the workpiece in contact with the
cutterhead.
Make sure the workpiece is free of nails, loose knots, and other
defects that could cause personal injury or damage the knives.
Remove wood chips and shavings only with the power off.
Stand to the side of the workpiece when feeding it through the
jointer to avoid potential injury from kickback and loose chips.
Keep your hands at least 3" (7.6cm) away from the cutterhead area.
Never pass your hands directly over the cutterhead.
Do not perform jointing operations on material shorter than
8" (20cm), narrower than ¾" (2mm), or less than ¼" (.65mm) thick.
To stop a workpiece before it is entirely fed through the machine,
press the Off button. Wait until the cutterhead has completely
stopped before removing material. Attempted removal while
cutterhead is turning may cause kickback.
To feed a workpiece:
1. Turn the red power switch on the control panel to on.
2. Press the green on button to turn on the cutterhead.
3. Feed the workpiece through the machine.
NOTE: If only workpieces of the same dimensions are run through
the jointer, the operator may want to occasionally adjust the fence
forward or backward to prevent wear on only one area of the knives.
Hand Placement When Feeding a Workpiece
At the start of the cut, your left hand holds the workpiece firmly
against the infeed table and fence while your right hand pushes the
workpiece toward the knives.
After the cut is under way, your left hand presses down on the new
wood surface so it rests firmly on the outfeed table and maintains
flat contact with the fence.
Before your right hand reaches the cutterhead area, move it to the
workpiece on the outfeed table. NEVER PASS HANDS DIRECTLY
OVER THE CUTTERHEAD.
NOTE: Push blocks are recommended for additional safety.
Proper Grain Direction
Avoid feeding workpieces into the jointer against the grain to prevent
chipped and splintered edges. Feed with the grain to obtain a
smooth surface.
