Assembly

Tools required for assembly:

Hoist, forklift, or one or more assistants Wrenches – 9/32”, 1/2” , 9/16” Hex wrenches – 4mm, 1/8”

Install Stand Legs

The sander is heavy; use

caution when lift in g.

1. Raise the sander from the floor using a

forklift, hoist or an assistant. (Place hoist straps through the c ar r iage arm or below the table mounting brackets. If using a forklift, fork below the tabl e m ount ing br acket s. See Figure 1, page 7.)

2. Position the assembly fixtures below the

columns so that the wider part of the plywood faces outward (Figure 3). Lower the sander columns into the assembly fixtures.

3. Mount the four legs to the columns, using

3/8x1-1/2 hex head bolts, 3/8 flat washers and 3/8 flanged lock nuts, using a 9/16” wrench. See Figure 3. Tighten the flanged lock nuts securely, making sure the legs remain in cont act with the plywood.

4. Lift the sander and remove the assembly

fixtures.

5. With the sander raised, install the four leg

glides, (or optional casters, not provided). See Figure 4. If using the casters, fir st lock the caster by pressing the large tab, in or der to remove the hex nut and flat washer.

Figure 3

Figure 4

Table Support Screws

The set screws on the table support s (Figure 5) have been tightened at the factory to eliminate free-play between the table supports and the columns during shipment. All four set screws

must be loosened and re-adjusted before operating either the height adjustment mechanism or the conveyor drive. Proceed

as follows:

Failure to follow the below

procedure may resul t in misalignment of th e drum and/or conveyor bed, or may damage the miter gears.

1. Loosen each hex nut with an open-end

wrench, then loosen the set screw with a hex wrench.

Figure 5

2. Re-tighten the set screw with your fingers

until it only li ghtly touches the column tube.

3. Hol d the set screw in positi on with the hex

wrench, and re-ti ghten the hex nut.

Install Handwheel

Mount the handwheel to the top of the height adjustment screw (Figure 6). Align one of the set screws with the flat on the height adjustment screw, and tighten both set screws.

Install the knob to the threaded hole in the handwheel, and ti ghten the hex nut agai nst the handwheel.

Install Conveyor Table

1. Lower the table mounting brackets by

rotating the handwheel.

2. Remove conveyor table from packaging,

and place it on the m ount i ng bracket s of the stand. The gear motor should be on the right, or inboard side of the sander as shown in Figure 7.

3. Secure the conveyor bed with four 3/8”x1”

hex head bolts, 3/8” flat washers and 3/8” flanged lock nuts.

4. Plug the motor cord into the control box

receptacle (Fi gur e 8) .

IMPORTANT: The conveyor belt has been overtight ened for shipping purpose s. It must be tensioned proper ly befor e operating the sander! See page 19.

Infeed and Outfeed Tables ( Optional

Accessory) See Figure 9.

1. Remove the lower hex cap screw (A) and

square nut (B) from the rail on the infeed side of the sander.

Figure 6

Figure 7

2. Slide a left hand mounting bracket (C) into

the end of the rail.

3. Align holes and re-i nstall the hex cap screw

(A) and square nut (B). Install a 3/8”x 1” hex head bolt (D), 5/16” flat washer (E) and flanged lock nut (F).

4. Ti ghten the hex cap screw (A) fi rst to align

the bracket, then ti ghten the fl anged hex nut (F) on the 3/8” screw.

5. Instal l a right hand mounting bracket (G) in

the same manner. NOTE: You will have to

pen the control box to remove the screw from the rail – remov e the front l ower screw and base panel (# 16 on page 38) of the control box.

Figure 8

Figure 9

6. Position the table (H, Figure 9) over the brackets, and install four 1/4”x3/4” square neck bolts (J) , 1/4” flat washers (K), and 1/ 4” hex nuts (L). Do not fully tighten yet.

7. The tabl e should be posi tioned ev en with or slightly bel ow the conveyor belt surface. T o check position, place a level or str aight edge near the left side of the conveyor and extending out over the table, as shown in Figure 10. Raise t he conveyor table until the drum holds the straight edge in pl ace, and adjust the infeed table unt il it i s ev en with or slightly below the conveyor belt surface.

8. Place the straight edge near the the right side of the conveyor table and repeat. Tighten all hex nuts on the infeed table.

9. Mount the outfeed table in the same manner as described above. (Removal of existing screws on the rails will not be necessary for the outfeed side. )

Figure 10

Leveling the Sander

Proper leveling is important for getting the maximum performance from your sander. Before making fine adjustments, place the unit where it will be used in the shop. Then adjust the four leg glides (see Figure 4) using a carpenter’s lev el placed on t he conveyor bed i n both X- and Y-ax i s positi ons. Make sure t he hex nuts on the leg glides are tightened securely against the sander legs.

If you are using the optional casters, level the sander after positioning the machine where it will be used most often. Place washers on the casters as needed to shim up the legs. Mar k the position of the legs on the f loor with tape so the sander can be returned to the same position.

Dust Collection

Dust collection is mandatory for a safe work environment and extended abrasive life. The sander is equipped wit h a 4” dust collecti on port at the back of the dust c ov er. It is designed t o be used with standard 4” dust collection hose connected to a hi gh volume dust c ollec tor wit h a minimum capaci ty of 600 CF M.

Using a shop v acuum is not recomm ended for this machi ne, but if used it should be a 16 gallon or larger canister type shop vacuum. This requires conv erting t he dust port down to 2-1/ 2”. An adapter is av ailable from your dealer (stoc k no. 80-2910) for converting to the 2-1/2” hose. Do not reduce hose si ze smaller than 2- 1/2”. For best results, follow recommendations of the dust collector manufacturer.

Installing Abrasives

An 80-grit abrasive strip is already installed on the drum of your sander. Page 28 offers information on the types of abrasive and their recommended uses.

Proper attachment of the abrasive strip to the drum is critical to achieving top performance from your drum sander. Abrasive strips do not have to be pre-m easured. The end of t he roll is first taper ed and attached to the left (out board) side of the drum. Then the strip is wrapped around the drum, and the second taper i s made for attachm ent to the right (inboard) side of the drum.

NOTE: When using JET Ready-To-Wrap abrasives, not all of the steps below are necessary. You can use the original abrasive strip mounted to the drum as a template for cutting your own stri ps.

1. Mark and cut a t aper at one end of the roll as shown in Figure 11. Because the t apered end should use al l of the l eft (outboar d) slot width, its end must be trimmed back three inches as shown.

Figure 11

Figure 12

2. Squeeze the fastener lever (Figure 12) on the outboard end of drum, and insert the tapered end of the abrasive so that i t uses most of the width of the slot. Release the fastener l ever to securely hol d the strip end to the fastener.

3. Begin wrapping the strip around the drum. The tapered edge of the strip end should follow the edge of the dr um.

4. Continue to wrap the abrasive in a spiral fashion by rotati ng the drum with one hand and guiding the strip with the other (Figure

13). Successiv e windings of the strip should be flush with previ ous windings without any overlap.

5. Mark the trailing end of the strip where it crosses the ri ght (inboard) end of the drum (Figure 14).

6. Remove the abrasive strip from the drum, and cut a taper as was done with the starting edge (see Figure 11). Note: The taper on the rem aining roll can be used as the taper for the starting edge of the next strip to be cut.

Figure 13

7. Rewrap the drum beginning at the left, as described in steps 2-4 .

Figure 14

8. You can use your f i ngers to work the i nfeed take-up fastener, but it will be more convenient to use the TUFTool supplied with your sander. Hol d the T UFT ool with t he red end pointi ng away from y ou (Figure 15) and insert its hook into the outside hole of the fastener lever (see Figure 17).

9. Lift the lever with the TUFTool, pulling the lever up until it touches the inside of the drum.

10. Turn the TUFTool counterclockwise and lower it ont o the abrasiv e strip, making sure it is holding t he paper tight (Figure 16).

11. Insert the t apered end of the abrasiv e strip into the slot and fastener. It may be necessary to trim the tapered end of the abrasive strip so that it does not “bottom out” against the i nsi de of the drum.

IMPORTANT: Leav e a gap – at least 1/ 8” – between the tapered strip and the closed end of the slot (Figure 16) to allow strip to be pulled into the fastener as needed. If necessary, trim the outside edge of the abrasive strip.

Figure 15

12. Hold the abrasive in place with your left hand, lift up the TUFTool and turn it clockwise while maintaining upward pressure. Slowly move the TUFTool away from you slightl y, then down, while easing it out of the hole. This rel eases the lever i n its proper positi on (Figure 17).

All abrasive strips will stretch in use and may stretch enough to allow the take-up lever to reach its lowest position so that it can not maintain tension on the strip. If this occurs, follow the abov e procedures to re-set the takeup lever.

Always remove TUFTool from machine before operating.

Grounding Instructions

Electrical connections must

be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury.

In the event of a malfunction or breakdown, grounding provi des a path of least r esistance 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 insert ed into a matching outlet that is properly installed and grounded in accordanc e wit h al l loc al codes and ordinances.

Do not modify the plug provided. If it will not fi t the outlet, hav e the proper outlet installed by a qualified elec 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 conductor . If repai r or replac ement of the electric cord or plug is necessary, do not connect the equi pment-grounding conduc tor 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 properly grounded. Us e only three wire extensi on c or ds that have three-prong grounding plugs and three- pole recept acles that accept the tool’s plug.

Repair or replace a damaged or worn cord immediately.

As received from t he factory, your drum sander is intended for use on a 20 am p, 110V dedicated circuit, whic h has an outlet and a plug that l ook like the ones illustr ated in Fi gure 18. The sander cannot be rewired to voltages other t han fact or y settings.

A temporary adapter, which looks like the adapter ill ustrated in Figure 19, m ay be used to connect this plug to a two-pole receptacle, as shown in Figure 19, if a properly gr ounded outlet is not available. The temporary adapter should only be used until a properly grounded outlet can be installed by a qualified electrician. This adapter is not applicable in Canada. The green colored rigid ear, lug, or tab, extending from the adapter, must be connected to a permanent ground s uch as a pr operl y grounded outlet box, as shown in Fi gur e 19.
