AIR SUPPLY
The efficiency and life of this tool depends on the proper supply of clean, dry, lubricated air at about 90 lbs. P.S.I., although higher or lower pressures
may be used. The use of an air line filter, pressure regulator and lubricator is recommended.Before connecting the tool, blow the air line to remove
water and dirt which may have accumulated. This is especially important for a new line or when the line has not been used for some time.
HOSE AND HOSE CONNECTION
The air supply hose is 3/8" I.D. If extension hose is necessary, use 1/2" hose, with couplings not less than 3/8" I.D.
INTENDED USE
Designed to cut up to 16 gauge steel; plastic and associated materials up to 3/32" thick. Sioux Tools cannot assume responsibility for damage to or
malfunction of a shear head used in combination with any drill other than those regularly supplied by Sioux Tools.
LUBRICATION
An oil supply to the air motor is important. SIOUX air line lubricators are recommended. Adjust to deliver 2 drops of SIOUX Air Motor Oil No. 288 per
minute. When air line lubricator is not used squirt several drops of oil into the air inlet before using. Gear case and shear head must be lubricated after
every 40 hours of operation with SIOUX Grease No. 289A. Failure to grease could void warranty.
SHEAR HEAD MAINTENANCE INSTRUCTIONS
ADJUSTMENT
To adjust the curl of waste material, the left side knife 54500 has elongated holes. Adjustment may be necessary after changing blades or material being cut.
Loosen cap screws 07102 and tap side knife 54500 either forward or backward so that curl of waste does not hit shear housing 12598 or work material while cutting.
DISASSEMBLY
To remove 53609 shear head from power unit and dismantle:
1. Loosen both rear cap screws 07102 three complete turns.
2. Remove shear head assembly 53609 from motor by pulling head firmly forward. Slight twisting action may be required.
3. Remove three cap screws 07102 completely from shear housing 12598. Be careful not to lose rear spacer bushing 54502 when removing rear cap screw.
4. Remove center blade 54499 from shear housing 12598 by tapping blade gently rearward. Be careful not to lose spacer bushing 54502 from hole
in center blade.
5. Side knives 54500 and 54501 will now drop out of shear housing.
ASSEMBLY
To assemble 53609 shear head and adapt to power unit:
1. Place the left side knife 54500 into position in the shear housing.
2. Insert center cap screw 07102 through housing and blade just far enough to slip spacer bushing 54502 over cap screw.
3. Place right side knife 54501 into position and push center cap screw through right side knife. Start cap screw into insert just enough to hold
blades in place. DO NOT TIGHTEN.
4. Insert spacer bushing 54502 into hole in center blade 54499 and lubricate with a good grade of bearing grease.
5. Install center blade 54499 into shear housing 12598 by tapping blade gently forward using a drift to line up hole in center blade with forward holes
in housing.
6. Insert and tighten forward cap screw 07102 making sure spacer bushing 54502 in center blade stays in position. Apply good grade of bearing
grease to clevis in center blade. WHEN SHEAR HEAD IS PROPERLY ASSEMBLED THE CENTER BLADE WILL PIVOT FREELY IN HEAD.
7. Insert rear cap screw 07102 into shear housing 12598 but do not completely tighten.
To install shear head assembly 53609 onto power unit:
1. Make sure rear cap screw and center cap screw 07102 are loosened three complete turns.
2. Place shear head onto unit and tighten cap screws 07102 snugly to lock head assembly in place. It may be necessary to gently tap the shear
head assembly into place if it does not readily slip onto the power unit.
NIBBLER HEAD
The Nibbler Head is recommended for CR sheet steel up to 18 gauge. Secure work piece. To start cut, place die opening of nibbler slightly onto the
edge of the work piece to steady the tool and ready it for the cut. Depress the trigger switch on the drive motor and guide the nibbler into the work.
Don't force it. Avoid double thickness of material, which exceed the 18 gauge recommended capacity. For cutting within perimeter of work piece, drill
a 1/2" diameter-starting hole and follow instructions above. If resistance to tool develops or cutting becomes difficult, discontinue cutting and check the
following: lubrication; chip clogging; thickness of material, sharpness of punch and die.
ADJUSTMENTS
The die rotates a full 360 degrees. To change position, loosen clamp nut and set die in desired position, tighten clamp nut. When cutting corrugated
metal, set die at 90 degrees to the motor unit. This will allow the motor and head to roll with the corrugations.
TO CHANGE PUNCH AND/OR DIE
1. Disconnect motor unit from power source.
2. Remove clamp nut 64089 and the die 64091 will slide off.
3. Remove retainer nut 64092 and the punch 64090 will slide out of the head.
4. Insert new punch into head and secure with retainer nut.
5. Insert new die and secure with clamp nut.
MAINTENANCE
Once every three months, depending upon usage, remove the nibbler head from the power unit by loosening clamping screw and pull the head with a
twisting action. Lubricate bearing surface of the eccentric nut with a good grade of bearing grease. Place nibbler head back onto motor unit. Eccentric
nut must engage with the link assembly as head is placed onto motor. Tighten clamping screw snugly to lock head assembly in place.
