Assembly

Tools needed for assemb ly:

• 10mm ope n-e nd wr ench

• Cross- poi nt (Phillips) scr ewdriver

• Combination square, or similar angle

measuring device.

Sander must be unplugged

from power source duri ng assembly. Remove the protect i ve coati ng from t he surfaces

of the sander and from any loose parts. This coating may be removed with a soft cloth moistened with kerosene (do not use acetone, gasoline or lacquer thinner for this purpose). After cleaning, cover the table surfaces with a good quality paste w ax.

Leave enough space aro und the sander for long workpieces and for general mai nte nance.

If needed, the s ander can be bo lted t o a t able or workbench using the holes in the base. If the sander has a tendency to walk or slide during operation, it must be bolted to a supporting surface.

Installing Belt Table

1. Unscrew t he stud. See Figure 1.

2. Position the bracket of the belt table over the

holes in the casti ng as shown, and re- insta ll the stud into its hole.

3. Place a flat washer onto a handle, and i nsert

the handle through the table bracket and into the hole. Scr ew the handle a ll the way into the hole.

NOTE: The handle is spring loaded; screw the handle in by rotating clockwise, then pull outward on the handle. Rotate the handle back to position, then release it, making s ure it seats itself upon the pin. Continue the process until the handle is tightened in the hole.

Installing Dust Chute

The sander has two 1- 1/ 2” diameter dust chutes. The dust chute for the belt is located on the belt cover. The dust chute for the disc should be installed as s how n in Figure 2, usi ng the si x (6) pan head machine screw s that are pr ovided.

Figure 1

The dust chutes ca n be co nnected to a vac uum system to collect dust particles.

Figure 2

Installing Disc Table

1. Position t he disc table at an angle, as show n

in Figure 3, and slide t he table on so that the trunnion slots fit over the raised tracks on the disc guard.

2. Install a flat washer onto each of the two

remaining handles. Insert the handle into the holes through the left and right trunnions. See Figure 4.

3. The gap between t he sandi ng disc and the

disc table s hould be a ma ximum of 1/16” . If it is larger than this, loosen the two socket head cap screw s on the disc g uard (o ne is shown i n Figure 4) and slide the disc guard to achieve this gap measureme nt.

4. When fi nished, tighten the tw o socket head

cap screws securely.

Figure 3

Figure 4

Insta lling Miter Gau ge

Insert the miter gauge bar into one end of the miter slot in the disc table. See Figure 5.

The miter ga uge ca n be used in either directio n in the slot to achieve the most effective positioning of the workpiece against the abrasive disc.

Installing Tension Handle

1. Place the 1/4” hex nut onto t he threads of

t he t ension handle .

2. Screw the tension hand le into the hole o n

the hub, t hen ti ghte n the hex nut against the hub. See Figure 6.

Figure 5

Figure 6

Grounding Instr uctions

This machine must be

grounded whi le in use to prot ect t he oper at or from electric shock.

In the event of a malfunction or breakdown, grounding pro vides a path of least r esist ance for electric current to reduce the risk of electric shock. This tool is eq uipped w ith an electric cor d having an equipment-grounding conductor and a grounding plug. The pl ug m ust be i nserted into a matching receptacle that is properly installed and gro unded i n ac cor dance with al l local codes and ordinances.

Do not modify t he plug pro vided. I f it will not fit the outlet, ha ve t he pr oper outlet insta lled by a qualified ele c trician.

Improper connection of the equipmentgrounding conductor can result in a risk of electric shock. The conductor, with insulation having an outer surface that is green with or without yellow stripes, is the equipmentgrounding conduc tor. If r epair or replaceme nt of the electric cord or plug is necessary, do not connect t he equipment-gr ounding conductor t o 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 t ool is proper ly gr ounded. Use only three wire exte nsion cor ds t hat have three-prong grounding pl ugs and t hree-pole receptac les that accept t he tool’s plug.

115 Volt Operation

As received from the factory, your sander is ready to r un at 115 volt oper at ion. This sander is intended for use on a circuit that has an outlet and a plug t hat looks like the one illustrated in Figure 7.

A temporary adapt er, like the adapt er in Figure 8, may be used to connect this plug to a twopole receptacle, as shown in Figure 8, if a properly grounded outlet is not available. The temporary adapter should only be used until a properly gro unded outlet can be installed by a qualified electrician. This adapter is not applicable in Canada. The gree n co lored rigid ear, lug, or tab, extending from the adapter, must be connected to a permane nt ground such as a properly grounded outlet bo x, as show n in Figure 8.

Figure 8

Extension Cords

Use proper e xtensio n cor ds . M ake sure the cord rating is suitable for the amperage of the machine’s motor . An undersized cord w ill cause a drop in li ne voltage res ulting in loss of power and overheating.

Use the chart in Figure 9 as a ge neral guide i n choos ing t he correct si ze cord. T he smaller the gauge number, the heavier the cord.

Adjustments

Tilting the Belt Table

The belt table ti lt s f rom zero (horizontal) down to 45°.

1. Loosen the ha ndle and adj ust t he table i nto desired position.

2. Check the angle with a machinist’s protractor or similar measuring device that has the required angle. Figure 10 shows a square being used to confirm the zero, or horizontal, posit ion. Place the sq uare flat on the table a nd against t he belt. Push agai nst the belt until the square is against the platen.

3. Make any ad justments t o the table a ngle as necessary until it is square with the belt.

4. Tighten the handle secure ly.

To avoid trapping the

workpiece or fingers between the table and abrasive belt, the table edge should be positioned a maximum of 1/16” from the abrasive belt.

Tilting the Disc Table

The disc table tilts f r om zero (horizonta l) down to 45°.

1. Loosen both handles and adjust the table until the indicator lines up with the desired angle on the scale. It is a good idea to confirm this angle using your angle measuring de vice placed f lat upon t he table and against the abrasive disc.

2. Figure 11 shows a square being used to confirm the zero, or horizontal pos ition of the disc table.

3. Make any necessary adjustments to the table angle. If the table is square with the disc but the angle indicator needs slight adjustment, loosen the screw on the indicator and shift the indicator as needed. Re-tighten t he screw .

4. Ti ghten bot h handle s secur ely .

To avoid trapping the

workpiece or fingers between the table and abrasive disc, the table edge should be positioned a maximum of 1/16” from the abrasive disc.

Figure 10

Figure 11

Use of t he Miter G auge

The miter gauge is used to sand accurate angles on workpieces. When using the miter gauge on t he hor izontal table positio n, yo u can sand a single angle. By tilti ng the disc table and using the miter gauge in combination with the table tilted, it is possible to sand compound angles as well.

The miter gauge rotates to 30° for bevel sanding. Loose n t he knob and r otat e the ga uge body until the pointer lines up with the desired angle on the scale.

Use a sq uare to co nfirm t hat the miter gauge is set at 90° ( perpendicular to t he disc). See Fig ure

12. If slight adjustment is needed:

1. Loosen the knob.

2. Adj ust the miter gauge body unti l it is flus h with t he squar e, and the square is flush with the disc.

3. Tighte n the knob.

4. Loosen the screw o n t he poi nter and adj ust the pointer until it aligns with 90° on the scale.

5. Tighten the screw on the pointer.

Belt P l at en

The belt platen (Figure 13) is used to properly support t he wor kpiece while sandi ng. T he platen is constructed of heavy steel to provide adequate support.

The platen should be adjusted so it is almost touching the back of the abrasive belt. Loose n the socket head cap sc r ew and adjust the platen to the desired position. Tighten the screw to secure the platen.

Figure 12

The platen c an be r emo ved for operatio ns s uch as stripping, contour sa nding, polis hing or ot her special operations. To remove the platen, remove the socket head cap screw and washer.

Be sure to re-install the platen to perform operations w here support of t he belt is required.

Figure 13

Abrasi ve Belt Rep lacemen t

1. Unplug the Sander from the power source.

2. Unscr ew and re move the two knobs on t he belt cover.

3. Remove the belt cover.

4. Rotate the tension handle (Figure 6) to loosen the belt, and remove the old belt fr om around the wheels.

5. Install the new belt around the wheels.

IMPORTANT: Some sanding belts have a directio nal arrow pr inted on the inside of t he belt. In these cases, the belt m ust be installed so the directio nal arrow is i n the same direct ion that the machine is running. Refer to the rotation arrow on top of the belt cover.

6. Install the belt cover and the two knobs.

7. Start the sander and c heck the belt track ing before sanding operations (See “Tracking the Abrasive Belt”).

Tracki ng the Abrasive Belt

“Tracking” refers to the manner in which the abrasive be lt is positio ned o n the wheels d uring operation. The belt should remain in vertical position wit hout shifti ng to o ne side or t he other of the wheel. If any shifting occurs, the belt needs to be tracked pr oper ly, as follows:

1. Disconnect sa nder fr om power source.

2. Remove t he side cover, and make s ure the belt is placed e venly over t he ce nter of the wheels. Loosen the tension and re-position the belt if necessary. Re-install the side cover.

3. M ove the belt by r otating the disc with yo ur hand (do not turn on the power yet). Observe the movement of t he belt on the top wheel.

4. If the belt slips to one side or the other, loosen the hex nut (Figure 14) wit h a 10mm open-end wr ench.

5. Rotate the tracking screw (Fig ure 14) with a 5mm hex wrenc h. If t he belt is slidi ng towar d the right, rotate the screw clockwise. If the belt is sliding toward the left, rotate the screw counterclockwise.

6. Continue this procedure i n small increments until the belt is tracking properly when moved by hand.

7. Re-connec t the sander to pow er, and cycle the on/off switch quickly to double check the tracking.

Figure 14

8. Re-connec t the sander to pow er, and cycle the on/off switch quickly to double check the tracking.

9. Make further adjustme nts as needed.

10. Tighten the hex nut to secure the setting.

Abrasi ve Di sc Repl acement

1. Unplug the sander fr om the power s ource.

2. Remove the dust cover and the disc table. To remove the disc table, remove the handles then tilt the disc table upward while pulling it away from the disc.

3. Peel off the old abrasive disc.

4. Thoroughly clea n the al uminum d isc surface using naptha or a similar non-flammable solvent t hat will dry film-f ree.

5. Pull the protective backing half-way off the new abrasive disc.

6. Carefully posit io n the new abr asive disc so it is centered accurately on t he aluminum disc.

7. When ac curately centered, remove the rest of the protective backing and press the abrasive disc firmly against the aluminum disc so complete adhesive contact is made.

8. Re-install dust cover and table.

9. Reconnect sander t o power source.

Alu mi num Disc Removal

The aluminum disc can be easily removed if needed; for example, to facilitate cleaning the aluminum disc when replacing abrasive discs.

1. Unplug sander from the power source.

2. Remove the disc table and the dust chute.

3. Rotate the disc until the set screw is accessible through the opening behind the disc guard. See F igure 15. Yo u may need to loosen the socket head cap screws (see Figure 4) o n the guard and shift it forwar d i n order t o clear the set screw.

4. Loosen the set screw with a 3mm hex wrench, and pull the aluminum disc off the motor shaft.

5. When re-mo unting the aluminum disc, make sure the key is properly seated in the keyway on the motor shaft. Tighten the set screw firmly when the disc has been mounted.

Figure 15

Operation

This sander is intended for dry sanding of metals. Do not use lubrica nt s.

Do not sand or polish

magnesium; it may create a fire haz ar d. Also, do not sand very small or very thin workpieces that cannot be saf ely contr olled.

Starting and Stopping the Sander

The on/off switch is located o n the side of the motor housing. Move the switch upward to the ON position to start the sander. Move the switch downward to the OFF position to stop the sander.

When the sa nder is not bei ng used, t he switc h can be locked in OFF position to prevent unauthorized use. Pull out the locking tab and store in a safe place. See Fig ure 16. The switch will n ot operate w it h the locking tab removed.

To use the sander, re - insert the locking tab.

Belt and Disc Movement

When the machine is turned on, the abrasive belt should be moving dow nward and the disc rotating clockwise. The motor is wired at the factory for correct rotation.

The workpiece should not contact the disc or belt during start-up. Before sanding, always allow t he motor to co me up t o operat ing speed, then observe the disc for wobble, r unout, or any unbalanced conditio n. I f t he disc is not operating accurately and smoothly, stop the motor and make repairs before atempting any sanding operations.

Always sand on the side of the abrasive disc that rotates downward. Sanding on the upward rotation side can cause the workpiece to catch and fly out of your hands.

The table must be a maximum of 1/16” away from the abrasive disc or belt.

Typ ical Operati ons

When sanding a compound angle you should check the accuracy of your setup by sanding a piece of scrap material before doing any finish sanding on the actual workpiece.

Figure 16

Figure 17 demonstrates a basic method of operation usi ng the miter gauge and disc table:

1. Set the angle you wish to sand using the scale on the miter gauge.

Figure 17

2. Tighten the miter gauge securely so the miter re fer ence a ngl e w ill not s hift w hile yo u are sanding.

3. Place the workpiece against the miter refer ence surface a nd slide it along the miter refer ence surface and into the sanding disc.

The following are just some of the many operations t hat can be perf ormed with yo ur JET Sander.

• Sharpening a wood chisel on the sanding belt using a block of wood. Use the block of wood to support the chisel and provide clearance for the chisel handle. See Figure

Maintenance

Before performing any

maintenance on the machine, disconnect it from the electri cal supply by p ulling out the plug or switching off the main switch. Failure to comply may cause ser ious injury.

Keep t he table surfaces clean and free of rust. If rust appears on the tables, use 000 steel wool with a paste mixture of household ammonia a nd good commercial detergent (or use a commercial rust remover available from most hardware stores.)

A light coat of paste w a x on t he tables wil l help protect them from tarnish and reduce friction between table and workpiece.

Note: Do not get pas t e w ax on the abras i ve belt or disc.

Check all fasteners for t ightness. Inspect the pow er cor d; if worn, cut, or damaged

in any w ay, have it replaced immed iately. Inspect the abrasive belt and disc. If either is

worn, replace it. Occasionally remove the belt cover and brush

out any shavings or debris from around the wheels.

Lubrication

All of the ba ll bearings are packed wit h grease and sealed at the factory. They require no further lubrication.
