for use by properly trained and experienced
perso nnel on ly. If you are no t fam iliar w ith the
proper and safe operation of a spindle sander,
do not use until proper training and knowledge
have been obtained.
5. Do not use this sander for other than its
intended use. If used for other purposes, JET
disclaims any real or implied warranty and holds
itself harm less from any inj ury t hat m ay res ult
from that use.
6. Always wear approved safety glasses/face
shields while using this spindle sander.
Everyday eyeglasses only have impact
resistant lenses; they a re not safety glasses.
7. Before operating this table saw, remove tie,
rings, watches and other jewelry, and roll
sleeves up past the elbows. Do not wear loose
clothing. Confine long hair. Non-slip footwear or
anti-skid floor strips are recom mended. Do not
wear gloves.
• Crystalline silica from bricks, cement and
other masonry products.
• Arsenic and chromium from chemically
treated lumber.
Your risk of exposure varies, depending on how
often you do this type of w ork. To red uce your
exposure to these chemicals, work in a wellventilated area and work with approved saf ety
equipment, such as face or dust masks that are
specifically designed to filter out microscopic
particles.
10. Do not operate this machine while tired or under
the influence of drugs, alcohol or any
medication.
11. Make certain switch is in OFF position before
connecting machine to power supply.
12. Make certain machine is properly grounded.

with machine unplugged from the power
source.
14. Remove adjusting keys and wrenches. Form a
habit of checking to see that keys and adjusting
wrenches are removed from the machine
before turning it on.
15. Keep safety guards in place at all times when
machine is in use. If removed for maintenance
purposes, use extreme caution and replace the
guards immediately after completion of
maintenance.
16. Check damaged parts. Before further use of the
machine, a guard or other part that is damaged
should be carefully checked to determine that it
will operate properly a nd perform its intended
function. Check for alignment of moving parts,
binding of moving parts, breakage of parts,

7.0 Electrical connections
The JOSS-S sander is rated at 115/230V power,
and is pre-wired for 115 volt. The sander comes with
a plug designed for use on a circuit with a grounded outlet that looks like the one pictured in A, Figur e 8.
Before connect ing to power source, be sure switch
is in off position.
It is recommended that the JOSS-S sander be
connected to a dedicated 15 amp circuit with a 15
amp circuit breaker or time-delay fuse marked “D”.
Local codes take precede nce over r ecomm endations.
7.1 Grounding instructions
6.8 Wrench storage
The provided combination wrench has a magnetic
strip, and can be placed against any metal surface.
Expose the adhesive on the additional magnetic
strip and apply anywhere on the cabinet surface.
The hex key can be stored against it.
6.9 Dust collection
A sander produces a significant volume of wood
dust; the use of a dust collection system is strongly
recommended. It will help keep the shop clean, as
well as reduce potential healt h hazards caused by
inhalation of wood dust. The collector should h ave a
capacity sufficient for this size machine; minimum
300 CFM is recommended.
JET has a line of dust collection systems available;
see your dealer or visit our website listed on the
cover.
Connect the hose of your dust collection system to
the 4-inch dust port (Figure 7) at rear of sander.
Secure tightly with a hose clamp.
1. All Grounded, Cord-connected Tools:
In the event of a malfunction or breakdown,
grounding provides a path of least resistance for
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 ordinances.
Do not modify the plug provided - if it will not fit the
outlet, have the proper outlet installed by a qualified
electrician.
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. The
cond uctor with insulation having an outer surf ace
that is green with or without yellow stripes is the
equipment-grounding conductor. If repair or
replacement 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 is properly
grounded. Failure to comply may cause serious
or fatal injury.
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tool's plug.
Figure 7
Repair or replace damaged or worn cord
immediately.
2. Grounded, cord-connected tools intended for use
on a supply circuit having a nominal rating less than 150 volts:
This tool is intended for use on a circuit that ha s a n
outlet that looks like the one illustrated in A, Figure
8. An adapter, shown in B and C, may be used to
connect this plug to a 2-pole receptacle as shown in
B if a properly grounded outlet is not available.
10
Page 11
The temporary adapter should be used only unt il a
properly grounded outlet can be installed by a
qualified electrician. This adapter is not permitted in Canada. The green-colored rigid ear, lug, and the
like, extending from the adapter must be connected
to a permanent ground such as a properly grounded
outlet box.

plug illustrated in D. Make sur e the tool is conn ected
to a n outlet having the sam e conf iguration a s the
plug. No adapter is available or should be used with
this tool. If the tool must be reconnected for use on
a different type of electric circuit, the reconnect ion
should be made by qualified service personnel; and
after reconnection, the tool should comply with all
local codes and ordinances.
7.2 Voltage conversion
To switch incoming power leads for 230 volt
operation, follow wiring diagram on ins ide cover of
motor junction box. A simi lar diagram is printed in
sect. 13. (In case of discrepancy, diagram on
machine takes precedence.)
The power cord plug must be replaced with a
UL/CSA listed plug rated for 230V.
Disconnect sander from power
source before making adjustments.
8.1 Rubber shields
Refer to Figures 9 and 10.
Front and rear rubber shields are co nnected at top
by hook-and-loop fasteners. Peel off top of shield to
access spindle area (Figure 9).
Figure 9: front shield
IMPORTANT: Before tilting table to maximum
degree forward, move top of shield from upper
position (A) to lower position (B).
7.3 Extension cords
The use of extension cords is discouraged; try to
position machines within reach of the receptacle. If
an extension cord is necessary, be sure to use one
heavy enough to carry the current your product will
draw. An undersized cord will ca use a drop in li ne
voltage resulting in loss of power and overheating.
Table 2 shows correct size to use depending on
cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The smaller the
gauge number, the heavier the cord.
