Sioux Tools SNH10S18 NIBBLER - Manual (Page 2)

Form ZCE797 2 Date 2012May9/B
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.
Air hoses that are not oil resistant or are not rated for the working pressure can burst.
Make sure that all air hoses are oil resistant and rated for the working pressure.
Air hoses that burst can cause injury.
Tools not operated at proper air pressure can operate erratically.
Do not exceed a maximum air pressure of 90 psig/6.2 bar or as stated on the tool’s nameplate or operating instructions. Use an
air regulator to maintain proper air pressure.
Erratic operation in power tools can cause injury.
Improperly repaired tools perform unpredictably.
Repair tools at an Authorized Sioux Service Center.
Tools that perform unpredictably can cause injury.
Tools left connected to the air supply can start unexpectedly.
Always remove tool from air supply and activate trigger to bleed air line before making any adjustments, changing accessories,
or doing any maintenance or service on tool. Make it a habit to check to see that all adjusting keys and wrenches have been
removed from tool before turning it on.
Tools starting unexpectedly and flying keys and wrenches can cause injury.

Store idle tools in a dry, high or locked-up place, out of the reach of children.
Misused tools can cause injury.
Tools with the actuator left in the “ON” position when an unexpected air pressure loss occurs can start unexpectedly when the air
pressure is restored.
Release the actuator if an unexpected loss of air pressure occurs.
Unexpected tool starts can cause injury.
Tools with the actuator left in the “on” position can cause unexpected starts when the tool is connected to the air supply.
Be sure actuator is off before hooking up air.
