Electrical
Grounding Instructions
This sander must be
grounded while in use to
protect the operat or from electric shock.
The temporary adapter should only be u sed until
a properly grounded outl et can be instal led by a
qualified electrician. This adapter is not
applicable in Canada. The green colored rigi d
ear, lug, or tab, extending from the adapter,
must be connect ed to a permanent ground such
as a properly grounded outlet box.
In the event of a malfunction or breakdown,
grounding prov i des a path of least resistanc e f or
electric current to reduce the risk of electric
shock. This tool is equipped with an electric
cord having an equipment-grounding conductor
and a grounding plug. The plug must be
plugged into a matching outlet that is properly
installed and grounded in accordance with all
local codes and ordinanc es.
Do not modify the plug provided. If it will not fi t
the outlet , have the proper outlet i nstalled by a
qualified el ectrician. Improper connecti on of the
equipment-grounding conductor can result in a
risk of electric shock. The conductor, with
insulati on having an outer surf ace that is green
with or without y ellow stripes, is the equipment grounding conduct or. If repai r or replac ement of
the electric cord or plug is necessary, do not
connect the equipment-grounding conductor to a
live terminal.
Check with a qualified electrician or service
personnel if the grounding instructions are not
completely understood, or if in doubt as to
whether the tool i s proper ly grounded. U se onl y
three wire ex tension cords that have thr ee- pr ong
grounding plugs and t hree-pole recept acles that
accept the tool ’s pl ug.
Repair or replace a damaged or worn cord
immediately.
230 Volt Operation
Referring to Fi gur e 9:
If 230V, single-phase operation is desired, the
following inst r uc tions must be followed:
1. Disconnect the machine from the power
source.
2. The JET O sci llati ng Edge Sander m ot or has
four numbered leads that are factory
connected f or 115V operation, as sho wn in
(A). For 230V operation reconnec t the l eads
as shown in (B).
3. The 115V att achment pl ug (C) supplied wit h
the Oscillating Edge Sander must be
replaced with a UL/ CSA listed plug sui table
for 230V operation (D). Contact your local
Authorized JET Service Center or qualified
electrician for proper procedures to install
the plug. T he Oscill ating E dge Sander must
comply wit h all loc al and national codes after
the 230-volt plug is installed.
4. The Oscil lating E dge Sander with a 230-v olt
plug should only be connected to an outlet
having the same configuration as shown in
(D). No adapter is available nor should be
used with the 230-volt plug.
115 Volt Operation
Referring to Fi gur e 8:
As received from the factory, your Oscillating
Edge Sander is ready to run at 115-volt
operation. This Oscillating Edge Sander, when
wired for 115 volt, is i ntended for use on a circuit
that has an outlet and a pl ug that looks like the
one illustrated in (A). A temporary adapter,
which looks li ke the adapter shown in (B), may
be used to connect this plug to a two-pole
receptacle if a properly grounded outlet is not
available.

Extension Cords
Make sure your extension cord is in good
condition. When using an ex tension cord, be sure
to use one heav y enough to car ry the curr ent your
machine will draw. An undersized cord will cause
a drop in the line voltage resulting in power loss
and overheati ng. Table 1 sho ws the cor rect si ze t o
use depending on t he cord length and namepl ate
ampere rating. If in doubt, use the next heavier
gauge. Remember, the sm aller the gauge number,
the heavier the cor d.

Motor Mount Tracking Adjustment
Referring to Fi gur e 14:
The OES-80CS comes with tracking adjustment
bolts (A) on t he motor pl ate. These are set at t he
factory and should not require any further
adjustment. If, howev er, you are not abl e to track
the belt with the Belt Tracking Adjustment
described in t he prev i ous section, the m ot or mount
bolts will have to be adjusted.
Note: The Motor Mount Tracking Adjustment is a
course adjustment. Use the Belt Tracking
Adjustment first for fine adjustment. If it cannot be
adjusted, then use the procedure described below.
To adjust:
1. Disconnect the machine from the power
source.
2. Slightly loosen the four motor mount nuts (B)
just enough so the tracking screws (A) can be
turned to make an adjustm ent.
3. Loosen the two locking hex nuts (C) that
secure the tracking screws (A).
4. Turn one screw (A) a 1/4 turn and rotate the
sanding belt by hand to observe which
direction t he adjustment i s causing the belt t o
move. If it is trav eling i n the direction needed
to correctl y tr ac k the belt go t o st ep 6.
5. If the bel t starts to tr avel in t he wrong di r ec tion,
back off a quarter turn and tighten the other
screw a quar ter tur n. Thi s should start t he belt
moving in the proper direction.
6. Tighten both loc king nut s (C) and m otor m ount
nuts (B). Then return to the Belt Tracking
Adjustment sect ion (previous page) and again
attempt to fine tune the tracking.
Figure 14
Table Adjustment
Do not position table below
sanding belt! Keep an overlap of at least 1/16”
between table and sanding belt to avoid
material and/or fingers getting caught! Failure
to comply may cause seriou s injury!
1. Loosen two lock knobs (A, Fig. 15).
2. Raise or lower work table to desired level.
3. Tighten two lock knobs.

Basic Operations
Removing the belt guard
exposes more o f the sandi ng bel t! Repl ace th e
belt guards immediately after completing any
sanding that requires its removal! Failure to
comply may cause seriou s injury!
Horizontal Sanding
For hor izontal sanding, the platen is locked in the
horizontal posi tion as shown (F) and the removable
fence (D) is secured to the table (E) as follows.
Referring to Fi gur e 16:
1. Place 5/16 flat was hers ( not shown) and guide
blocks (B) on two 12mm lock knobs (A) – Note:
the 12mm refers to the threaded shaft length.
2. Insert the guide blocks (B) into the miter slot
(C) and position the lock knobs (G) on the
table (E) as shown.
3. Place the removable fence (D) on the table
and secure by tightening the lock knobs
(G, Fig. 16 and Figure 17).
Figure 16
The backstop (H, Fig. 17) can also be used by
swiveling the drum guard & dust port (J, Fig. 17)
out of the way and plac ing the backstop pi n in the
positioni ng hol e and securing in plac e with t he lock
knob (K, Fig. 17) and 5/16" flat washer . Note: This
is better shown in Figure 18. The drum guard &
dust port (J, Fig. 17) can then be returned to the
position shown.
Vertical Sanding
Referring to Fi gur e 18:
For vertical sanding, the platen (G) is locked in the
vertical position as shown and the backstop (H)
and/or the mit er gauge (B) m ay be used.
Miter Gauge
1. Slide the guide bar ( D) of the miter gauge (A)
into the miter slot (C) on the table.
Figure 17
2. Set the miter angle; then secure the mi ter by
tightening the lock handle (B).
Backstop
Place the back stop pin in the po sitioni ng hole and
secure in place with the lock knob (E) and 5/16"
flat washer (F).
Figure 18

Contour Sanding
Referring to Fi gur e 19:
Contour sanding is done f rom the extension table
mounted on the motor where the sanding belt
wraps around the drive drum (D). To set up the
sander for cont our sandi ng:
1. Loosen the t wo lock knobs (C) that secure the
drum guard & dust port (E).
2. Swing the end guard (E) back, bringing the
drive drum (D) into view.
3. Tighten the loc k k nobs (C).
4. Mount the extens ion t able (A) to the sander by
inserting the post (B) into the bracket (F).
5. Set the table to the desir ed height, then secure
into positi on by tightening the lock knob (G).
Important: When the extension t able (B) is not in
use, the drum guard & dust port (E) should always
be in the closed posi tion so the drive drum (D) is
not in view.
