Model G0505 (Mfg. since 4/04)
No list of safety guidelines can be complete.
Every shop environment is different. Always
consider safety first, as it applies to your
individual working conditions. Use this and
other machinery with caution and respect.
Failure to do so could result in serious per-
sonal injury, damage to equipment, or poor
work results.
Workpiece
Inspection
Some workpieces are not safe to plane or may
require modification before they are safe to pass
through the planer.
Before cutting, inspect all
workpieces for the following:
•
Material Type: This machine is only intended
for planing workpieces of natural wood fiber.
Attempting to plane workpieces of any other
material could lead to serious personal injury
and property damage.
•
Foreign Objects: Inspect lumber for defects
and foreign objects (nails, staples, imbedded
gravel, etc,). If you have any question about
the quality of your lumber, do not use it.
Remember, wood stacked on a concrete floor
can have small pieces of stone or concrete
pressed into the surface.
• Large/Loose Knots: Loose knots can
become dislodged during the planing opera-
tion. Large knots can cause kickback and
machine damage. Always choose workpieces
that do not have large/loose knots when plan-
ing.
• Wet or "Green" Stock: Avoid planing wood
with a high water content. Wood with more
than 20% moisture content or wood exposed
to excessive moisture (such as rain or snow),
will plane poorly and cause excessive wear
to the knives and motor. Excess moisture can
also hasten rust and corrosion of the planer
and/or individual components.
•
Excessive Warping: Workpieces with exces-
sive cupping, bowing, or twisting are danger-
ous to cut because they are unstable and
often unpredictable when being planed. DO
NOT use workpieces with these characteris-
tics!
• Minor Warping: Workpieces with slight cup-
ping can be safely supported if the cupped
side is facing the planer table. On the con-
trary, a workpiece supported on the bowed
side will rock during planing and could cause
kickback or severe injury.
Depth of Cut
The planing depth of cut is controlled by using the
elevation crank on top of the machine. Rotating
the crank clockwise raises the cutterhead.
Depth of cut is read directly from the inch/mil-
limeter scale on the front of the planer, as shown
in
Figure 14.
Figure 14. Depth of cut indicator and scale.
Depth of Cut
Indicator & Scale
One complete turn of the crank raises or lowers
the cutterhead approximately
5
⁄
64
" (2mm). The
range of material thickness that can be planed is
13
⁄
64
"– 6" (5mm–152mm).
Although the correct depth of cut varies according
to wood hardness and workpiece width, we rec-
ommend a maximum depth of cut no more than
1
⁄
32
". A series of light cuts will give a better end
result and put less stress on the planer than trying
to take off too much material in a single pass.
