Assembly

Tools required for assembly:

1 Flat head screwdriver 1 Set of open-end wrenches 1 Set of Hex wrenches 1 Adjustable wrench

Installing Drum Head

The drum sander must be bolted down to a workbench or stand. If you pur c hased o ne of the JET stands, plac e the sander b ase on t he stand and align the holes. Secure the sander to the stand using f our 3/8” x 3/ 4” hex cap screws and four 3/8” fl at washers. See F igure 4.

Attach the handwheel ( A, Fi gure 6) t o the hei ght adjustment screw, and tighten the two set screws with the 4mm hex wrench suppli ed.

Installing Conveyor Table

1. Rai se the drum as f ar as it will go by t urni ng

the handwheel (A, Fi gur e 5) cl oc k wise.

2. Align t he four holes in the convey or with the

four holes in the base of t he dr um assembl y .

3. Secure the conveyor in place with four

5/16”-18 x 3/4” sock et head cap screws (B, Figure 5), f our 5/16” lock washers and four 5/16” flat washers.

4. Plug the motor cord into the control box

receptacle.

IMPORTANT: The conveyor belt has been over- tensioned for the purpose of shipping. Before

operating the sander, adjust the belt tension according to i nstr uc tions on page 15.

Infeed and Outfeed Tables (Optional Accessory)

1. Bolt the base bracket (B, Figure 6) to the

sander base with two 3/ 8”-16 x 1” hex head cap screws (C) and two 3/8” flat washers (D). Tighten the screws.

Figure 4

Figure 5

2. Mount the table (A) to the base bracket (B)

with four 1/4"-20 x 3/4" carriage bolts (E), four 1/4" fl at washers (F) and four 1/4" hex nuts (G). Note: Leave the carriage bolts loose for now.

4. Repeat for the other table.

Figure 6

Dust Cover

To open the dust cover, push in on the k nob (C, Figure 5) and lift. The latch can be adjusted using the screw behind it.

Dust Collection

Dust collection is mandatory for a safe work environment and extended abrasive life. The 2244 Plus is equipped with a 4” du st c ollection por t at the top of the dust cov er . It is designed t o be used with standard 4” dust collection hose connected to a high volume dust collector (minimum 500 CFM), as shown in Fi gur e 7.

WMH Tool Group offers a variety of Dust Collectors and Ai r Filtration Unit s. Contact your local distributor for more information.

Installing Abrasives

An 80-grit abrasive strip is already installed on the drum of your sander. Page 23 offers information on other abrasives available 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 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.

Figure 7

Figure 8

(not applicable to “Ready - To-Wrap” strips)

1. Mar k and cut a taper at one end of t he roll

as shown in Figur e 8. Because the tapered end should use al l of the l eft (outboar d) slot width, its end must be trimmed back as shown.

2. Rai se the fastener lev er (D, Figur e 9) on t he

outboard end of drum, and insert the tapered end of the abrasiv e (E, Figure 9) so that it uses most of the width of the slot. Release the fastener lever to securely hold 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

10).
