ADjUSTING DEPTH OF CUT
Proper cutting depth should be determined
according to the hardness, gumminess or
moisture content of the material being cut, as
well as the feed rate, and is largely a matter of
experience. Start with a light cut and increase
the depth setting if the planer moves freely
through the workpiece with no excessive load
on the motor. Do not change depth of cut
while planing.
The cutting depth is determined by the
difference in height between the adjustable
front shoe, and the fixed rear shoe of the
planer. As the front shoe is adjusted, it retracts
and exposes the blade, which can then
TRIGGER "ON/OFF" SWITCH
Hold the tool with both
WARNING
hands while starting the
tool, since torque from the motor can
cause the tool to twist.
To turn tool "ON", depress the "Lock-OFF"
button and squeeze the trigger switch. To turn
the tool "OFF", release the trigger switch which
is spring loaded and will return to "OFF"
position automatically.
To increase switch life, do not turn switch on
and off while tool and drum are held against a
workpiece.
When the trigger is released it activates the
electrical brake to stop the blade quickly. This
feature is especially useful when making
repetitive cuts.
PLANING ACTION
Check that the workpiece is held in place
securely on your work surface. Stand
comfortably, hold the planer firmly with both
hands. With the planer fully adjusted, place
the front shoe on the workpiece, (be certain
that the cutter drum is not in contact with the
work) and start the planer. With pressure on
the front shoe, and the fence against the side
of the work (to control the width or angle) feed
the planer steadily until the rear shoe fully
engages the workpiece. Gradually transfer
pressure to the rear shoe and continue planing
to the end of the cut. Feed the planer at a
uniform and reasonable rate, which does not
put excessive strain on the motor or blades.
Do not pull the planer back over the surface
already cut. Use progressive cuts until you are
Operating Instructions
BRAKE
remove the desired amount from the
workpiece. The cutting depth is graduated
from 0 to 1/16 of an inch, and the "0" indicates
the blade is fully retracted.
Adjusting depth of cut:
adjustment knob until the indicator engages
the detent which indicates the desired cutting
depth on the depth scale (Fig. 1).
The planer may be set to cut any depth from 0
to 1/16 of an inch.
PORT SELECTOR LEVER
Moving the port selector lever to position 1
(towards front of tool) discharges chips to the
left, while position 2 (towards rear of tool)
discharges chips to the right (Fig. 1)
near the desired depth, and then re-adjust to a
light cut for the final pass to obtain a good
surface finish.
The motor may stall if
CAUTION
improperly
overloaded. Reduce the pressure (feed rate)
or depth of cut to prevent possible damage to
the tool if the motor labors.
STANDARD GUIDE FENCE
The guide fence can be used to control the
width of the cut or for simply providing added
stability and protection when cutting materials
that are up to 3-1/4" wide.
Note: When used for rabbeting, the fence
must be attached to the left side of the tool.
(Fig. 1).
Installing the guide fence: Place the wing knob
through the appropriate hole in the guide
bracket and screw into preferred side of the
housing. Securely tighten wing knob. Setting
the cutting width: Place wing knob through the
appropriate fence arm and slide along the
guide bracket to the desired position. Securely
tighten wing knob. Be certain that the flat
washer (supplied) is fitted between the bottom
of the guide fence and wing knob or the guide
fence is likely to slip.
DELUxE GUIDE FENCE
The deluxe guide fence can be used to control
the width of the cut or for simply providing
added stability and protection when cutting
materials that are up to 3-1/4" wide, with the
additional capability of guiding the planer on
any angle up to 45 degrees, to allow edge
chamfering and beveling (Fig. 7).
