Warning

1. Read and understand this entire manual before attempting assembly or operati on.

2. Read and understand the warnings po sted on the m achine and i n thi s manual. Fail ure to comply wit h

all of these warnings m ay cause seriou s i njury.

3. Replace the warning labels if they become obscured or removed.

4. This sander is designed and int ended for use by proper ly t rained and experi enced personnel onl y. If

you are not f amiliar wit h the proper and safe operati on of a sander, do not use unt il proper training and knowledge have been obtained.

5. Do not use this sander for other than it s intended use. If used for other pur poses, JET disclaim s any

real or implied warranty and holds itself harmless fr om any injury that may result from that use.

6. Always wear appr oved safety glasses/face shields while u si ng this sander. Everyday eyeglasses only

7. Before operati ng this sander, rem ove tie, rings, watches and other j ewelry, and r oll sleeves up past

the elbows. Remove all loose clothing and c onfine 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 periods 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 .

• Crystalline silica from bricks, cem ent and other masonry products.

• Arsenic and chrom ium 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 operate this machine while tired or under the influence of drugs, al c ohol or any m edic ation.

11. M ak e c er tain the switch is in the OFF position bef ore connecting the machine to the power supply.

12. M ak e c er tain the machine is properly grounded.

13. M ak 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 machi ne is in use. If removed for maintenance

purposes, use extreme caution and replace the guards immediately.

16. M ak e sure t he sander is firmly secured to the stand or work table 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.

18. Provide for adequate space surroun ding work area and non-glar e, overhead lighting.

19. Keep the floor around the machi ne clean and free of scrap material, oil and grease.

20. Keep visitors a safe dist anc e from the work area. K eep children away.

21. M ak e y our workshop chi ld proof with padlock s, m ast er switc hes or by r em oving starter keys.

22. Giv e your work undivi ded attention. Looki ng around, carryi ng on a conversati on and “horse-play” ar e

careless acts that can r esul t in serious injury.

23. M aintain a balanc ed stance at all t imes so that you d o not fall or lean against mov ing parts. Do not

25. Use the ri ght t ool at the corr ect speed and f eed r ate. Do not forc e a tool or att achment to do a job for

which it was not designed. T he ri ght tool will do the job better and safer.

26. Use recom mended accessories; improper accessories m ay be hazardous.

27. Maintain tools with care. Keep abrasives clean for the best and safest performance. Follow

instructions for lubricating t he machine and changing accessories.

28. Always feed stock against the r otation of the drum.

29. Keep your hands clear when feeding parts onto the conveyor. The part will be forced down as it

begins to feed, causi ng a pinc hing ac tion bet ween the par t and t he conv eyor bed. Nev er reach i nto a running mac hine. Turn off sander and disconn ect from power befor e att empting to r etriev e parts fr om beneath the drum.

Referring to Fi gur e 5:

1. Place the sander (C) ont o the stand previously assembled.

The sand er is very h eavy. Use a hoist or assi st ance when moving to avoid inju ry to self and equipmen t.

Align the f our threaded mounting holes of the sander base (C

After installing the drum head to the stand, finish tightening all mounting hardware that was previously hand-ti ghtened during the stand assembly.

Conveyor Table Installation

1. Raise the drum as f ar as it will go by turning the

handwheel (A) clockwise.

2. Place the conveyor (D) onto the sander

base (C1). Align the four holes in the conveyor (D) with the

four holes in the sander bas e.

3. Secure the conveyor i n place with four 5/16” x

3/4” socket head cap screws (K), four 5/16”

lock washers (N) and four 5/16” flat washers (P ).

4. Plug the sander's motor cord into the

receptacl e of t he contr ol box (D

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

2. Mount the table (A) to the base brack et (B) wit h four 1/4" -20 x 3/4" carriage bol ts (E), four 1/ 4" flat washers (F) and four 1/4" hex nuts (G). Note: Leave the carriage bolts loose for now.

The infeed and outfeed table is an optional accessory.

1. Bolt the base bracket (B, Fi g. 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.

3. Place a str aight edge on the conv eyor bed and extending out over the extension table. Raise or lower the ex tension t abl e until it is l evel wit h, or slightly below, the surface of the conveyor belt. Tight en the hex nuts (G).

4. Repeat for the other table.

Dust Cover

To open the dust cover, push in on the knob (A, Fig. 7) and lif t. The lat ch can be adj usted using the screw behind it.

Dust Collection

Dust collection is mandatory for a safe work environment and extended abrasive life. The 22-44OSC is equi pped with a 4” dust collection por t at the top of the dust cover. It is designed to be used with standard 4” dust collection hose (B, Fig. 7) connected to a high volume dust collector (minimum 500 CFM) as shown.

JET offers a variety of Dust Collectors and Air Filtration Units. Contact your local distributor for more informati on.

Figure 7

Installing Abrasives

An 80-grit, 3-1/8” wide abrasive strip is already installed on the drum of your sander.

Proper attac hm ent of the abr asiv e stri p t o the drum is critical to achieving top performance from your drum sander. Abr asive strips do not have to be premeasured. The end of the roll is first tapered and attached to the left (outboard) side of the drum. Then the stri p is wrapped around t he dr um, and the second taper is made for attachment to the right (inboard) side of the drum.

Note: You can use the original abrasive strip mounted to the dr um as a templat e for cutting y our own strips.

1. Mark and cut a taper at one end of the roll as shown in Figure 8. Because the tapered end should use all of the left (outboard) slot width, its end must be trimmed back as shown.

2. Raise the fastener lever (D, Fig. 9) on the outboard end of drum, and insert the tapered end of the abrasive (E, Fig. 9) so that it uses most of the width of the slot. Release the fastener l ever to securely hold the str ip end to the fastener.

Figure 8

Figure 9

3. Begin wrappi ng the strip around t he drum. The tapered edge of the str ip end should follow the edge of the drum.

4. Continue to wrap the abrasive in a spiral fashion by r otati ng the drum with one hand and guiding the strip with the other (Figure 10).

Successive windings of the strip should be flush with previous windings without any

overlap.
