Jet Tools 22-44 Pro-3 Sander User Manual


 
Table Height
A large, 7 ¾”-diameter cast-iron handwheel
adjusts the table height within its 4” range.
Each full turn of the handwheel changes
table height by 3/32" for ultra precise
sanding thickness control. The handwheel
operates a screw and gear drive that controls
both ends of the table to keep it level for
maximum sanding accuracy.
An easy to use depth stop is built onto the
support post and makes sanding many boards to a specific thickness fast, easy and very
accurate. The depth stop is tool free so you can concentrate on sanding rather than finding
a wrench!
The large handwheel (left) makes table height changes
effortless. The tool-free depth stop (right) makes
sanding several boards to a precise thickness virtually
automatic.
Digital Read Out
The included DRO
has several functions,
not the least of which
is allowing ultra
precise table to drum
settings.
The DRO (digital read out) comes pre-installed on the JET 22-44 Pro-
3 Drum Sander (#649600). This digital measuring device makes
setting ultra precise sanding depths, or returning to one with 0.01”
resolution simple and easily repeatable. The DRO can be set to
display either inch or mm readings with the push of a button. The
battery as well as a spare is supplied with the machine.
The DRO has several distinct functions. Probably the most commonly
used function is the “Absolute Measurement”. Sand a piece of wood
on the JET 22-44 Pro-3 Drum Sander, measure that thickness with
digital calipers and then set the DRO to that dimension. You can then
sand other pieces to match that thicknesses quickly with exceptional
accuracy.
The DRO also has a “Relative Measurement” that can show the amount of material to be
removed from a previously sanded board. “Hold” records a setting so you can return to it
later. “TOL” (tolerance) allows setting upper and lower tolerance limits. All of the
functions and their setting procedures are fully described in the instruction manual.
A gamut of great features including an extra powerful 3-HP motor, large capacity
conveyor with infeed and outfeed tables and the precision of a dead flat table, balanced
aluminum sanding drum backed with a DRO height adjustment system. As well the JET
22-44 Pro-3 comes equipped to be mobile with heavy duty double locking casters. The
JET 22-44 Pro-3 is a great machine for anyone tackling jobs that require large pieces to
be sanded from the hobbyist woodworker to the small job shop.
