Proper Use
The use which the machine is intended for, is described in Section 1.2.

The following applies to safe operation:

The details at Section 1.3, “Technical Data“, count as mandatory operating limits and ratings.

Shearing other animals, in particular dangerous animals such as beasts of prey and the like, counts as misuse. This could lead to circumstances dangerous to life and limb.

Safety Principles

Drive Connections
Only connect the machine up to undamaged, inspected shearing drive shafts & motors (shearing plants). Damaged shafts or motors can cause lock up which can cause serious injury. Defective installations can cause an electric shock or a short circuit.

(Illustration 0)
Product Parts
Make sure to use the correct type of drive coupling, i.e. only connect a worm-drive type handpiece to a worm-drive type shearing drive ( Illustration 1, Item 1) and a pin-drive handpiece to a pin-drive shearing drive (Illustration 1, Item 2). Do not mix the two system as it can cause malfunction and unexpected behaviour of the whole system.
Drive Connections
Servicing and cleaning must only be carried out when the machine is removed from the drive\ (shearing plants).

Never leave the machine unsupervised when connected to a shearing drive. Keep children away from the working area and store the machine out of their reach.

Servicing and Checking Requirements
Only operate the machine if it is undamaged and in a proper condition. Any defects to the housing (barrel) or the drive shaft connection should be rectified by a repair or service agent

Noise Emission / Personal Protective Equipment

Ear Protectors IconWear Ear Protectors !
Typical sound emission when working are >70 dB(A). We recommend that ear protectors should always be worn when working.

Wear Protective IconWear Protective Goggles and Gloves !
For your personal protection we recommend that you wear protective goggles and gloves.

Gloves Icon Personal protective equipment is to be provided by the operator.

Other Dangers
Should evidence of dangers or potential dangers, not directly related to the shearing of animals, occur during operation, we would ask you to inform us. This also applies to dangerous technical deficiencies

Essential Operator Skills
Operating the machine safely makes only small demands of the operator. However, it is essential that they are observed and carried out.

  • The operator must be experienced in handling the animals to be shorn.
  • The operator must have read and understood the instructions or have been instructed by and expert in the machine’s use and have had the potential dangers explained. Children are not permitted to operate the machine.

Putting into Operation

Controls and Operation Notes
Stop Icon There are dangers inherent in the improper use of mechanical equipment, especially stock breeding equipment! Therefore, before using the machine, you should observe the following accident-prevention measures:

  • Observe the advisory notes listed at 2.4.1 (drive connections).

  • Avoid all contact with the moving shearing blades (comb & cutter).

  • Even when the shearing drive (shearing plant) is switched off, do not handle the area of the shearing blades as long as the machine is connected to the shearing drive. Always disconnect the machine from the shearing drive first when working on the shearing blades/ machine.

  • Never shear wet animals. Wet wool may enter the machine body (barrel) and cause lock up.

  • Generally, never plunge the clipper and clipperhead into liquids such as water, soapy water, diesel, petrol, etc. This may cause serious injury to mechanics and motor.

  • Never put your handpiece in a vice, it will disfigure the barrel and the back end will become tight.

  • Never attempt to interchange parts from another model/type or brand of handpiece.

  • Only use original shearing blades (combs & cutters; Illustration 5 ). Do not use damaged shearing blades with blunt, missing or broken off teeth. Only work using sharp shearing ades, ground according to advisory notes listed at 4.3 (Resharpening the Shearing Blades)
    Combs & Cutters

  • Looking out for foreign bodies (wire, wood, etc.) in the fleece and remove them before beginning to shear.

  • Wear suitable work clothes. Do not wear any loose fitting clothing or items of jewellery which could get caught up in moving machine parts. We would recommend in the strongest terms that protective goggles and ear protectors are worn.

  • Never insert any object into any of the machine’s apertures

  • Noise from the machine can worry animals. Considerable injury can be caused as a result of being kicked by an animal or being crushed by its body weight.

  • Animals should only be shorn if unauthorised persons have been excluded from the shearing area.

  • Only shear in well-ventilated spaces (dust) and never near objects or gases likely to explode.

  • We recommend you use a comb for no longer than an hour and a cutter for no longer than 15 minutes before you change them for a sharp comb and cutter These Safety notes must be complied with in all cases

Shearing Adjustment using the Tension Nut
Before putting into operation, make adjustments as follows:

Before Shearing:
With the machine disconnected from the shearing drive: ensure that the Yoke’s carrier (chicken feet) cone pins mesh precisely into the positioning holes in the cutter ( Illustration 2, Item 2 ). Tighten the tension nut until resistance is first noticeable (I llustration 2, Item 1 ). Then tighten the tension nut a further 1⁄4 turn.
Combs & Cutters
Connect the handpiece to the shearing drive (observe advisory notes listed at 2.4.1) and start operating the shearing drive motor. Slacken off the tension nut ( Illustration 3) until the shearing blades exert almost no more contact pressure (noise level rises).
Machine Disconnected

Note IconCaution! If the tension is slackened off too much, the cutter can fly off causing injury.  Now tighten the tension nut slowly until the noise level becomes muffled and some resistance is detectable as you tighten the tension nut. The pressure should now be correctly set. Begin shearing. If it still does not cut properly, you will have to add a little more tension.

During Shearing
Provided the shearing blades are properly sharpened (ground) the shearing system works with much less pressure having to be applied than with traditional shearing machines. Care should be taken, therefore, to ensure that the blade tension is not set too high. Too high tension causes more friction and reduces the life expectancy of the shearing hand piece as well as the shearing blades. Slightly adjust the blade tension from time to time during shearing (max. 1⁄4 turn).

Hair may collect between the shearing blades, if the tension nut is insufficiently tightened at the start of shearing. This will have an adverse effect on further shearing progress or make itquite impossible. If this happens, the shearing blades must be disassembled, cleaned, oiled and re- fitted as described at 4.2 (Fitting the Shearing Blades)

Lubrication
Before and During Shearing
A thin layer of oil on the cutter and the comb plate ( Illustration 4, Item 4 ) is essential for good shearing results and so as to increase the life of the machine and its shearing blades. All other moving parts must also be well oiled ( Illustration 4, Item 3 ) .
Utter And The Comb Plate
Only use our special clipper oil or a paraffin oil meeting the ISO VG 15 specification. This oil is non-toxic and produces no irritation on contact with the skin or the mucous membranes. This paraffin oil degrades to some 20% after 21 days (CEC-L-33-T-82).

You cannot over oil ! The more often you oil, the cooler it will run and the longer it will last. Especially if you are shearing llamas, alpacas or other camelides, even more frequent oiling of comb and cutter may be needed.

Always oil the machine before use, and at least at every cutter change.

Oil the following parts

  • Before you assemble the blades to the hand piece turn the handpiece upside down (Illustration 4,Item 1) and run oil into the centre post cup through the hole illustrated.
  • Oil the tension sleeve or top of tension pin (Illustration 4,Item 2).
  • Turn it back over and oil tension pin cup (Illustration 4,Item 3).
  • Wet the cogs with oil.
  • Oil down the ferrule to lubricate the outer back half joint and the pin or worm drive.
  • Oil the ball through the hole in the top of the barrel.
  • Oil the cutter and comb when set ( Illustration 4, Item 4 ).

Do not put oil or grease between the tension nut and the tension sleeve as this will cause loss of tension.

Grease
Once a week remove, clean and regrease the following parts:

  • Yoke’s carrier (chicken feet) – Remove the comb and cutter, turn the yoke’s carrier at 90 degrees to the fork and pull them out using a pair of pliers. Clean them and the locating holes in the fork and apply a small amount of grease on the yoke’s carrier shank and replace it making sure they twist freely in the fork when replaced. If they don’t, remove and clean more thoroughly.
  • Back Joint Caps – Remove the back joint spring, take off the caps and clean out any old grease and dirt. Apply a small amount of grease in the cap and reassemble.
  • Tension Sleeve – Remove the tension nut, tension sleeve and tension pin. Remove all the grease from inside the tension sleeve and from the tension pin. Apply a good amount of grease to the inside of the tension sleeve and replace it, remember to remove all grease from the outside of the tension sleeve before replacing the tension nut.

Bearings
The shearing handpiece is fitted with bearings which are sealed and will never need oiling or greasing.

Servicing

Before starting any servicing work, disconnect the handpiece from the shearing drive.

Cleaning
After shearing, remove all oil from the machine by rubbing it down with a dry cloth and carefully clean the outside of the shearing handpiece and the shearing blades with a dry brush. Then oil the parts to prevent rusting. Even the smallest rust spots on the blades can adversely affect shearing or make it completely impossible.

Fitting the Shearing Blades
A pair of shearing blades consist of a comb plate ( Illustration 5, Item 2 ) and an cutter ( Illustration 5, Item 1 ). When fitting the blades care should be taken to ensure that the correct surfaces come to rest against each other. The blades are fitted as follows:

Loosen the tension nut ( Illustration 3 ) and place the machine on a hard surface so that the  comb blade fixing screws lie uppermost. Slacken off the screws ( Illustration 6 ) and remove both the old shearing blades.
Slacken Off The Screws
Ensure that the new shearing blades are clean. Particular care should be taken to ensure that the ground surface are free of dirt; if not, even newly ground shearing blades will not shear satisfactorily.

Place the new cutter in the yoke’s carrier (chicken feet) cones ( Illustration 7 and 2, Item 2 ) and push the new comb plate between the loosened screws ( Illustration 8 ). Now tighten the comblade fixing screws until you can just move the new comb plate sideways by han d.
Chicken Feet
loosened Screws
Now turn the machine over so that the tension nut is against uppermost.

What is now important is that you rest the blades against each other in such a way that the ground surface of the comb plate projects approx. 1.5 – 2.0 mm beyond the tips of the cutter ( Illustration 9 ) at the same time all sharp corners of the cutter indicated at (c) must be within the indicated area (b)

Once you have adjusted the shearing blades, set the position of the comb plate and tighten up the comb blade fixing screws.

Check that the shearing blades have been correctly fitted and that the pressure yoke’s carrier (chicken feet) cones ( Illustration 2, Item 2) are situated in the holes provided in the cutter. Now tighten up the tension nut until the cutter is pressed against the comb plate and you can feel a slight resistance.

Resharpening the Shearing Blades
Only work with sharp shearing blades. Replace blunt blades or those with missing teeth. Proper resharpening can only be done with a special shearing blade grinder and by a trainedtechnician or experienced Shearer. For correct shearing blade grinding technique, please follow the instructions which comes with every Heiniger shearing blade grinder.

Storing
Only store the shearing hand piece in a dry place. Do not connect it to a shearing drive if you suspect any liquid has got into it. There is then the risk of a corroded and therefore seized drive mechanism which, if you try to run the hand piece, can cause injury.

Make it a habit to store the machine between use, store it well-cleaned, oiled and with tension slackened off, in a clean, dry place, out of the reach of children

How tob

Note: This Section is for experts only. Do not follow this instructions if you are not a trained technician or experienced Shearer with good knowledge of mechanics. Wrong or unprofessional repair and maintenance of the handpiece can cause malfunctions which lead to serious injury, damage and/or reduced life expectancy of your shearing handpiece. Warranty will be void if unprofessional repair or maintenance has been carried out.

emove Fork
Unscrew tension nut and remove tension sleeve and tension pin, unscrew fork safety screw. Fork may now be removed. It is not necessary to remove the centre post when removing the fork. Reassemble in the opposite order.

Fitting a new ball
Remove fork and ball, place new ball on the crank pin using a piece of wire or a pencil with the flat side of the ball pointing to the crankhead or rear of the handpiece.

Replacing the tension pin cup
Remove fork, punch out the old tension pin cup. Place the new tension pin retaining spring on to the tension pin cup before replacing it into the fork, tap the cup into the fork making sure the slope on the top of the cup faces directly towards the ball race or the back of the fork.

Remove and replace Back Joint
Remove comb and cutter and screw firm tension on tension nut, put a screwdriver down through the oil hole in the top of your handpiece so it goes between the fork and barrel, remove the cog from the end of the crankshaft using a cog spanner. The back joint will now slide out off the barrel.

Reassemble Back Joint

  • First clean the back joint thoroughly.
  • Place your new seal (Illustration 10, Item 18) over the inner back half joint (I llustration 10, Item 23 ) with the two lips facing the cogs. Ensuring that the inner lip on the seal is not twisted, slide the seal half way up the inner back half joint.
  • Oil the bush inside the barrel and the inner back half joint.
  • Slide the back joint into the barrel until the seal is in the barrel
  • Firmly push the seal into place then push the remainder of the back joint home.
  • And replace the special cogs.
  • Always use pairs of identical special cogs by the same part numbers for replacement

Fitting Bearing Kit
This is not a difficult job when using a SpecialTool Kit ( Illustration 11 ). It’s very important not to rush, pull everything apart and throw away all the components you will replace. Clean up all the remaining parts and fit the new ones carefully, taking note of the very important points
listed below, read the following instructions and cross them off once you have completed each point.
SpecialTool Kit

  • The bearings in your hand piece are small and the balls in them are delicate, each time you go to hit the bearing “think first”. The force must never travel through the balls i.e.: if you are fitting the outer bearing into a casing ( Illustration 12, Item 1 ) hit the outer rim only, not the seal or the inner rim. And when fitting the bearing onto a shaft ( Illustration 12, Item 2 ) hit the inner rim only. If you do hit the wrong rim, or the seal, it will distort the balls, do not use this bearing anymore, throw it away as it will run hot and wear rapidly.
    Fitting

  • Do not clamp the barrel in a vice.

  • Use (replace) all the parts contained in the bearing kit.

  • Never re-use old bearings.The bearings will have been damaged during removal.

  • Do not use a steel hammer as this will jar and damage the tool and the bearing, use a nylon hammer or a piece of wood.

  • Use a SpecialTool Kit ( Illustration 11 ) they are not expensive and will last a life time.

  • Use a small piece of hard wood to work on as a bench.

  • Make sure you know the difference between the distance washer and the wave washer.The wave washer is wobbly, the distance washer is flat.

Replace Bearings „Step by Step“

  • Remove fork.

  • Remove both cogs.

  • Remove back joint spring and caps.The back half joint will now come apart.

  • Remove the inner back half joint from the barrel.

  • Remove the circlip using the circlip pliers.

  • Clean the circlip groove thoroughly (this is important).

  • Place the punch (tool no. C; Illustration 11 ) through the front of the barrel ( Illustration 13) and onto the recess in the middle of the crankhead. Holding the barrel and punch in one hand gently knock the crank shaft free from the barrel. The bush, wave washer and front bearing will come with it. Don’t allow the bush or the crank shaft to hit the floor as damage may occu

  • Remove the pin or worm drive.
    Front Of The Barrel

  • Slide the punch down where the pin or worm drive was removed, holding the outer back half joint ( Illustration 19 ) in one hand gently knock out the old bearing and clean the back half joint thoroughly.

  • Place outer back half joint ferrule thread down onto the piece of wood and select one of the smaller of the three bearings ( Illustration 20 ), tap it gently into position using tool no. A.

  • Remove inner back half joint bearing with the punch coming from the crank shaft head end ( Illustration 19 ), holding the inner half back joint with one hand gently knock out the old bearing and clean the inner back half joint thoroughly.

  • Place the front of the inner back half joint on the piece of wood and gently tap the smallest of the two remaining bearing ( Illustration 20 ) into position using tool no. A.
    Remaining Bearing

  • Remove front bearing ( Illustration 14 ), put the small end of tool no. D onto the piece of wood, place the crank head inside the big end, the distance washer will now rest on the tool. Screw the thread inside tool no. B onto the crank shaft making the crank shaft twice as long, hit the tool until the bearing is free of its seating, unscrew the tool and remove the bearing and the distance washer

  • To fit the front bearing, place the crank head on the piece of wood ( Illustration 21 ) with the pin facing down over the edge, place the distance washer (the flat one) over the crankshaft  and then the remaining (biggest) bearing. Using tool no. B with the thread to the top hit the tool until the bearing is positioned against the seat behind the crank head. Take care that the distance washer does not get caught between the bearing and the seat behind the crank head, the distance washer should always be free moving
    Crank Head

  • Clean the barrel thoroughly (now is a good time to fit a rug if required).

  • Ensuring all bearings are seated properly before beginning to reassemble.

  • Place the mouth of the barrel on the piece of wood ( Illustration 15 ) and lower thecrankshaft with bearing fitted into the barrel, slide small end of tool no. D into the barrel and gently tap the tool until it rests against the end of the barrel.
    Piece Of Wood

  • Place the new wave washer over the crank shaft and lower it onto bearing.

  • Clean the bush and coat it and the inside of the barrel with light oil, slide the bush down on top of the wave washer.

  • Fit NEW circlip (do not over compress the circlip when fitting because it will rub on the inner back half joint and make the back end tight) inside the barrel, then using the small  end of tool no. D against the circlip, tap the circlip into its seat. Make sure the circlip is seated properly in the groove.

  • Reassemble the two back half joints with new grease in the back joint caps.

  • Place a NEW seal over the inner back half joint (see back joint removal and replacement and Illustration 10 ) and oil liberally.

  • Coat inner back half joint and inside of barrel with oil and slide inner back half joint into the barrel and screw the cog onto the end of the crankshaft.

  • Reassemble the worm or pin drive and cog.

  • Refit the fork making sure the flat side of the ball is facing the crank shaft ( Illustration 22).
    Flat Side

Fitting Pin Drive Pin
The pin drive pin is tapered, identify the small end of the broken pin and tap this small end of  the pin with a punch to remove it. Tap in the new pin gently, don’t hit it hard or you will crack the end of the shaft. Place the big end of your pin on an anvil or something solid and round off (or burr over) the small end of the pin ensuring it is a good fit into the shaft, finish this job by filing the small end flush with the shaft. Make sure the big end does not protrude out past the outer rim of the drive coupling, if it does this will rub on the tube and run hot, file off the
excess.

Adjust Centrepost using a Post Guide
The post has a notch in the bottom around from the screwdriver slot ( Illustration 16). Use this notch as a setting mark and once you have the handpiece cutting well remember or write down where this mark is, this will enable you to reset the post to the original position should the need arise.
Screwdriver Slot

  • Set a freshly ground comb and cutter that is 3mm thick.

  • Apply normal tension to cutter.

  • Move the cutter until the ball is at the bottom of the fork and the cutter is in the middle of the comb.

  • Loosen the centre post lock nut.

  • Insert the Post Guide ( Illustration 17) in the hole and sit the first ledge on the fork at the front of the ball race
    Insert The Post Guide
