1.6 Slide the hollow grind handle assembly (item31 ) off the hollow grind shaft (item 28), ex-amine the dehider blade, and repeat steps1.4--1.6 until the hollow grind extends to the tipof the dehider blade teeth.

1.7 Repeat steps 1.1--1.6with the remaining dehiderblade.

1.8 Turn off the electric switch (item 37).

2 Sharpening and Dubbing: For new blade setsand blade sets previously sharpened on BR--5 /BR--5A / BR--5B / BR--5D models.

2.9 Turn the adjusting screw (item 103) counter--clockwise until the dehider blade tooth contactsthe grinding wheel (item 5).

2.10 Tap the dehider blade tooth against the grindingwheel (item 5) two or three times.

2.11 Rotate the dehider blade one tooth:

2.11.1 Pull back on index handle (item83) and turnblade retaining knob (item 91) counter--clockwise one tooth.

2.11.2 Release index handle (item 83) to engagepawl (item 94) in the dehider blade tooth.

2.12 Repeat steps 2.10--2.11.2 for remaining teeth onthe dehider blade. The last tooth on the dehiderblade must be cut free hand.

2.15 Line up the pawl (item 94) between the secondand third tooth on the dehider blade.

2.16 Pivot the indexing armassembly (30, 43, 47--57)towards the grinding wheel (item 5). Allow theblade to make contact with the grinding wheel(item 5).

2.17 Rotate the dehider blade one tooth (see step2.11).

2.18 Repeat steps 2.16-2.17 for remaining teeth onthe dehider blade.


2.20 Remove dehider blade and replace with un-sharpened, un--dubbed dehider blade. See notesbelow:

2.20.1 Follow steps 2.1--2.5, pages 7 and 8.

2.20.2 Follow step 2.6.1. on page 8. Note: If youadjusted for a lighter or heavier dub on theprevious blade of the set, the red dot must berealigned with the reference line on thebushing.

2.20.3 Do not follow step 2.6.2. on page 8. Note:The adjusting screw must be kept in thesame position for both blades in the set.

2.20.4 Follow steps 2.7--2.8, page 8.

2.20.5 Do not follow step 2.9, page 8. Note: Theadjusting screw must be kept in the sameposition for both blades in the set.

2.20.6 Follow steps 2.10--2.19, pages 8 and 9.

2.21 On newer models, the step on blade holder shaft(item 90) has been lengthened to allow dubbingof both blades at the same time. If your blade re-conditioner has this longer step, the secondsharpened blade can be placed, hollow sidedown, on top of the first blade. Complete dub-bing by following steps 2.13--2.19.

3 Deburring:

3.1 Deburr dehider blade:

3.1.1 Follow steps 1.1--1.4, page 7.

3.1.2 Push the hollow grind handle assembly(item 31 ) against the hollow grind wheel

(item 27 ) for about a tenth (1/10) of a se-cond.

3.2 Repeat steps 3.1.1--3.1.2 with the remaining de-hider blade.


OPERATION INSTRUCTIONS -- 2Note: If you have a new blade set or a blade set that hasbeen previously sharpened on a BR-5 / BR-5A/BR-5B, please return to “OPERATION INSTRUC-TIONS - 1.”Note: Always keep dehider blades as a matched set.Refer to parts diagram and parts list, pages 4 through 6for referenced items.1 Hollow Grind:1.1 Follow hollow grind instructions 1.1--1.8, page

7.2 Sharpening: Forblade sets previously sharpened

on other machines.2.1 Apply machinist blue (dye) to the teeth of both

blade halves to be resharpened.2.2 Place the blade with the hollow side up on blade

shaft (item 90).2.3 Pull index handle (item 83) and rotate blade

shaft (item 90) to engage pawl (item 94) in oneof four detent holes.For BR--5D only:Depress and hold locking pin (item 106) and ro-tate blade shaft (item 90) until pin engages oneof the four detent holes.


2.5 Rotate the index block assembly into bottomposition and lock it in placewith knob (item 76).Refer to Figure 2, page 8.

2.6 Position red dot on the dub adjustment bushing(item 101) in line with the reference line onbushing (item 99).

2.7 Turn on the electric switch (item 37).2.8 With the pawl (item 94) completely disengaged

from any teeth, line up the first tooth to the leftof the blade cut--out with the grinding wheel.

2.9 Bring the tooth toward the grinding wheel (item5) by pivoting the indexing arm assembly.

2.10 Turn the adjusting screw (item 103) counter--clockwise until the blade tooth contacts thewheel (item 5).

2.11 Tap the dehider blade tooth against the grindingwheel until no additional material is removedfrom the blade. Light taps will prevent burningthe tips of the blade.

2.12 Rotate the adjustment screw (item 103) count-er--clockwise slightly without disturbing therelationship between the red dot on the dub ad-just bushing and the reference line on bushing(item 99).

2.13 Repeat steps 2.11--2.12 until all the machinistblue is removed from the first tooth.

2.14 Rotate the adjust screw 1/4 turn counter--clock-wise without disturbing the dub adjust bushing(item 101). The adjusting screw should not berotated until this blade set is complete.

2.15 Engage the pawl (item 94) in the first slot to theleft of the blade cut--out. Refer to Figure 5.

until all teeth are sharpened.2.20 Examine all teeth. If anymachinist blue remains

on any teeth, return to step 2.8, and rotate the ad-justing screw 1/8 turn counter--clockwise with-out disturbing the red dot or the dub adjust bush-ing.

2.21 Repeat steps 2.11 -- 2.19.

2.22 When all teeth are sharpened, remove the bladefrom the blade shaft and deburr the blade as de-scribed in section 3, page 9.

2.23 Being careful not to disturb the adjusting screw(item 103), place the second half of the blade seton the blade shaft.


2.25 Repeat steps 2.8, 2.9, and 2.11. Note: Do nottouch the adjusting screw (item 103).

2.26 Repeat steps 2.14 through 2.22.
