the elbows. Remove all loose clothing and confine l ong hair . Non-slip footwear or anti-skid floor strips are recommended. Do not wear gloves.

8. Wear ear protector s (plugs or muffs) during extended peri ods of operation.

9. Some dust created by power sanding, sawing, grinding, drilling and other construction activities

contain chemi cals known to cause cancer , bir th defects or other r eproductiv e harm . Some exampl es of these chemic als are:

• Lead from lead based paint.

• Crystalli ne sil ic a from bricks, cement and other masonry pr oduc ts.

• Arsenic and chromium from chemically treated lumber .

Your risk of exposure varies, depending on how often you do this type of work. To reduce your exposure to these chemicals, work in a well-ventilated area and work with approved safety equipment, such as face or dust masks that are specifically designed to filter out microscopic particles.

10. Do not oper ate this machine while tir ed or under t he i nfluence of drugs, alcohol or any medi c ation.

11. Mak e c ertain the switch is in the OFF position before connecting the machine to the power supply.

12. Mak e c ertain the machine is properl y grounded.

13. Mak e all machine adjustments or maintenance with the machine unplugged f r om 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 the machine is in use. If removed for maintenance

purposes, use extreme caution and replace the guards immediately.

16. Make sure the sander is firmly secured to the stand or work tabl e before use.

17. 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 and perform its intended function. Chec k for alignment of moving par ts, binding of moving parts, breakage of parts, mounting and any other condi ti ons that m ay affect its operati on. A guard or ot her part that i s damaged should be properly repaired or replaced.

Assembly

Tools requi red for assemb ly:

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 handwhe el ( 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.

Figure 4

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” socket 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

4. Repeat for the other table.

Figure 6

Dust Cover

To open the dust c ov er, push i n on t he knob (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 port 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.

JET offers a variety of Dust Col lectors and Air Filtration Uni ts. Contact your local distribut or or visit our website 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.

Figure 7

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 t apered 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 attac hment to the right (inboard) si de 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.

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 abr asive (E, Figure 9) so that it uses most of the width of the slot. Release the fast ener lever to securely hold the strip end to the fastener.

Figure 8

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

Figure 9

3. Begin wrapping the strip around the drum.

The tapered edge of the strip end should follow the edge of the drum.

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).
