OPERATION

STARTINg AND STOPPINg JOINTER
1. The on/off switch (A) Fig. 21 is located on the front of the
jointer. To turn the machine "ON", move switch (A) up to
the "ON" position.
To turn the machine "OFF", move the switch down to the
2.
"OFF" position.
Make sure that the switch is in the "OFF"
position before plugging in the power cord. In the event of
a power failure, move the switch to the "OFF" position. An
accidental start-up can cause injury.
LOCKINg SWITCH IN THE "OFF" POSITION
IMPORTANT: When the machine is not in use, the switch
should be locked in the "OFF" position to prevent
unauthorized use. To lock the machine, grasp the switch
toggle (B) and pull it out of the switch (Fig. 21). With the switch
toggle (B) removed, the switch will not operate. However,
should the switch toggle be removed while the jointer is
running, the machine can be turned "OFF," but cannot be
restarted without re-inserting the switch toggle (B).
VARIABLE SPEED CONTROL
Your jointer is supplied with variable speed control (A) Fig. 23A
that enables you to operate the machine at cutterhead speeds
between 6,000 and 11,000 RPM. Speed indicators of 1-2-3-4
and 5 are provided on the speed dial. When the pointer on
the speed knob is pointing to 1, the cutterhead speed will be
6,000 RPM; 2 – 7,250 RPM; 3 – 8,800 RPM; 4 – 9,750 RPM;
and 5 – 11,000 RPM.
SPEED SELECTION CHART
Use the speed selection chart (Fig. 23B) to determine the
proper setting for your workpiece.
NOTE: For convenience, make a copy of this chart and post it
on or near the machine.
DEPTH OF CUT ADJUSTMENT
The jointer can be set to cut any depth from a very thin shaving
to 1/8 inch (3.2 mm) deep. A dual English/Metric scale (A)
Fig. 24, and pointer (B) are provided to indicate the depth of
cut. To adjust for depth of cut, loosen lock knob (C) and turn
adjusting knob (D) clockwise to lower and coun ter clock wise to
raise the infeed table. Raising the infeed table decreases the
depth of cut, while lowering it will increase the depth. After the
infeed table is at the desired setting, tighten lock knob (C).
NOTE: For best results, final positioning of the infeed table
should always be made from the bottom to the up position.
