Safety regulations

Introduction
This section describes the safety regulations that must always be taken into account when using the shearing system. Reading the operating instructions is mandatory for anyone working on or with the machine. The operating instructions must be kept in a safe place accessible at all times.
Correct use
The intended use of the shearing machine is described in Section 1.2.
Principles of safety
Connection to the drive
Only connect the device to undamaged, tested shear drive shafts & motors (shearing systems). Damaged shafts and motors can cause blockages which can lead to serious injuries. Faulty electrical installations can lead to electric shock or a short circuit. Take care to use the correct type of drive coupling, i.e. only connect a shearing handle with a “Worm-Drive” drive shaft to a shearing system with a “Worm-Drive” coupling (Fig. 1). Maintenance and cleaning work may only be carried out after the device has been disconnected from the drive (from the shearing system). Never leave the machine unattended while it is connected to the shearing drive. Keep children away from the work area and keep the device out of the reach of children.
Mandatory maintenance and inspections
Only operate the shearing machine in an undamaged and orderly condition. Defects in the shearing handle or shearing system must be repaired by a repair and service center.

Noise emissions / personal protective equipment

Wear hearing protection!
The noise emission at work is normally 72 – 75 dB(A). We recommend that you always wear hearing protection when working.
Wear safety glasses and gloves!
For your personal protection, we recommend that you wear safety glasses and gloves.

Personal protective equipment must be provided by the operator.

Requirements for the operator
For the safe use of the shearing machine, it is imperative that the instructions in this operating manual are observed and followed.

The operator has read and understood the operating instructions or has been instructed in the system’s operation by a specialist and has been made aware of risks.
The operator has experience in handling the animals to be sheared. Children and infirm persons (without supervision) are not allowed to operate the shearing machine.

Commissioning

Checks and operating instructions
The improper use of electrical equipment, especially animal husbandry equipment, is associated with dangers!
Therefore please observe the following accident-preventing measures before commissioning:

Follow the recommendations in Section 2.3.1 (connection to the drive).
Avoid any contact with the moving shearing blades (comb & blades).
Do not touch the shearing blades while the machine is still connected to the drive, even if the drive (shearing system) has been switched off. Always disconnect the machine from the drive before working on the shearing blades/machine.
Do not shear wet animals. Wet wool can penetrate the shearing handle and cause a blockage.
Never immerse the shearing machine or shearing head in liquids such as water, soapy water, diesel, petrol, etc. This will cause considerable damage to the mechanisms and motor.
Never clamp the shearing handle housing in a vice, as the housing can deform which can lead to dangerous malfunctions.
Never try to exchange spare parts for those of another type/brand of the shearing handle.
Only use original shearing blades. Do not use damaged shearing blades with blunt, missing or broken teeth. Only work with well-sharpened shearing blades that have been sharpened according to the recommendations in these instructions.
Check the animal’s fur for foreign bodies (wire, wood, etc.) before shearing and remove them before starting the shearing process.
Wear appropriate working clothes. Do not wear loose-fitting clothes or jewellery. These can get caught in the moving machine parts. Wearing safety glasses and hearing protection is strongly recommended.
Never insert an object into an opening in the machine.
The noise of the machine can disturb animals. A kick or the body weight of the animal can cause serious injuries.
nimals should only be sheared if children do not have access to the shearing site.
Only shear in well-ventilated rooms (dust) and never near explosive objects or gases.
We recommend not using the comb for more than an hour and the upper blade for more than 15 minutes.

These safety instructions must be followed in all cases.

Adjusting the shearing blades and the shearing head
Make the setting before commissioning as follows:
Before shearing: With the machine switched off: Make sure that the tapered pins of the pressure forks engage precisely in the position holes of the upper blade (Figure 2, item 2). Tighten the adjusting screw until the first noticeable resistance is felt (Figure 2, item 1). Then tighten the adjusting screw by another 1/4 turn. Now connect the shearing handle to the drive (follow the recommendations in Section 2.3.1), then start the drive motor. Loosen the adjusting screw (Figure 3) carefully until the shearing blades have almost no contact pressure (noise level increases).
Caution! If the adjusting screw is loosened too much, the upper blade may come loose and cause injury. Now slowly tighten the adjusting screw until the noise level becomes muffled and you feel resistance when tightening the adjusting head. Turn the adjusting head back 1/4 turn. The pressure should now be well adjusted. Start to shear. If the cut is not yet correct, increase the contact pressure again slightly with the adjusting screw.
During shearing:
If the shearing blades are correctly ground, the shearing system works with much less pressure, which reduces wear and tear and thus considerably improves the service life of the shearing blades. It is therefore important to ensure that the blade pressure is not set too high. During shearing, the blade pressure can be easily adjusted from time to time (max. 1/4 turn). If shearing is started with an insufficiently tightened adjusting screw, hairs can accumulate between the shearing blades and impair the further course of the shearing or even make it impossible. Should this occur, the shearing blades must be disassembled, cleaned, oiled and reassembled.

Lubrication
Oil the upper and lower blades every 10 minutes!
Oil every half hour:
Apply a few drops of high-quality oil to the tip of the fork head, gears and around the eccentric roller (through the oil hole on the tip of the handpiece). Loosen the clamping nut and bring the handpiece into a vertical position, then put some oil in the pressure bushing, then lift the fork head and put some oil in the inside to oil the spherical head cover. (see figure) No oil should be allowed to get onto the contact surface between the adjusting screw and the pressure bushing at the top as this will affect the sensitivity for the correct adjustment of the shearing pressure.

Daily lubrication
Remove the pressure bushing and apply a generous amount of grease to the inside of the sleeve. Also apply a small amount of grease to the back teeth.
Weekly lubrication
Remove the pressure forks, pour a generous amount of lubricant into the holes on the fork body and reattach the pressure forks. Ensure that they are secured in the hole. Remove the joint assembly by unscrewing the teeth, pour a small amount of lubricant into the ring-shaped spaces between the bushing and the adjusting nut. The lubricant must be of high quality and suitable for use at temperatures up to 120 °C. Regular lubrication will extend the life of your shearing handpiece.
No lubrication for bearings
Ball bearings are built into the handpiece and do not need to be oiled or greased.

Maintenance

Before starting maintenance work, disconnect the shearing handle from the drive.

Cleaning
After finishing shearing, remove oil from the shearing handle by rubbing it with a dry cloth and carefully clean the outside and the shearing blades with a dry brush. Then oil the parts to prevent rust formation. Even the smallest rust spots on the shearing blades can impair shearing or make it completely impossible.
Installing the shearing blades

A pair of shearing blades consist of a lower blade – also called the comb plate or comb (Figure 4, item 2) and an upper blade – also called the cutter (Figure 4, position 1). When installing the shearing blades, it is important to ensure that the correct surfaces come into contact with each other. The shearing blades are installed as follows: Loosen the adjusting screw (Figure 3) and place the machine on a hard surface so that the comb plate screws are at the top. Loosen the screws (Figure 5) and remove the two old shearing blades. Ensure the new shearing blades are clean. Particular care must be taken to ensure that the ground surfaces are free of dirt. Otherwise, satisfactory shearing performance cannot be achieved even with newly ground shearing blades. Place the new upper blade in the driving tapers of the pressure forks (Figure 6 + 2, item 2) and push the new lower blade (comb plate) between the loosened screws (Figure 7). Now tighten the comb plate screws so that you can just about move the new lower blade sideways by hand. Now turn the machine over so that the adjusting screw is pointing upwards. It is now important that you place the blades on top of each other so that the ground surface of the lower blade extends approx. 1.5 to 2.0 mm beyond the tips of the upper blade. However, all of the sharp rear edges of the upper blade must lie within the marking. Once you have adjusted the shearing blades, fix the position of the lower blade and tighten the comb plate screws. Check that the shearing blades are fitted and that the driving tapers of the pressure forks (Figure 2, item 2) are located in the holes provided for them in the upper blade. Now tighten the adjusting screw until the upper blade is pressed against the lower blade and you feel a slight resistance.
Sharpening the shearing blades
Only work with sharp shearing blades. Replace blunt or faulty blades with missing teeth. The correct regrinding of shearing blades is only possible with special machines and by a specialist or an experienced shearer. The correct instructions for grinding can be found in the manual supplied with each shearing blade sharpener.
Care of individual parts of the shearing head
The pressure forks:
Ensure that each of the two pressure forks can rotate freely in the fork. Remove the pressure forks once a week. Clean them and the front of the fork head thoroughly. Pull out the pressure forks by hand or using pliers. Always put a small amount of grease in the holes of the fork when removing the chicken feet. If the taper and the tip on the outer side of the chicken feet are worn out, they must be replaced as soon as possible.
Contact pressure:
each end of the clamping bush has a different size. The larger end fits into the fork tip and the smaller end into the pressure bushing. Increase the pressure on the upper and lower blade by turning the clamping nut. If the clamping nut is overtightened, the handpiece, upper and lower blade will quickly overheat. This also leads to the upper and lower blades not cutting properly. If the machine no longer cuts properly, replace the upper and lower blades with newly ground ones. If sufficient tension is not generated, consider replacing the worn pressure pin, fork tip and pressure bushing.

Screw:
the retaining spring for the pressure forks is fixed to the fork head by a screw and must not be loose.
Removing and replacing the forkhead:
remove the entire assembly and eccentric roller (see Figures 3 and 4)
Disassembly procedure:
the fork body can be removed without removing the spherical head screw. First, loosen the clamping nut, then remove the pressure pin and the clamping bushing, then the locking screw behind the clamping nut and the forkhead with the eccentric roller.
Replacing the forkhead:
remove the lubrication cap on the tip of the handpiece. Apply a small amount of grease to the eccentric roller (ball) and the race of the fork head. Attach the roller to the ball shaft (pin) using a pen, screwdriver or similar tool. Make sure that the flat side of the roller is facing the crank axle. Place the crank and roller bearings in the lower position of the handpiece. Guide the forkhead over the front into the handpiece and over the roller. After you have thoroughly checked that the spherical head cover is correctly seated on the spherical head screw, attach the locking screw and tighten it.Adjusting the spherical head screw: the spherical head screw can be correctly adjusted during production and is suitable for any blade thickness. If it has to be readjusted, use a half-worn upper blade (approx. 3.5 mm) and a lower blade of any thickness, turn the eccentric roller on the eccentric shaft to the uppermost position and adjust the spherical head screw by one of the following methods:
Adjust by hand:
Loosen the spherical head screw and screw it in or out to set the distance from the top of the roller to the top surface of the fork head race to 3.65 mm. Retighten the nut for the spherical head screw (see Figure A) Adjustment using the setting gauge:
(The setting gauge is specially made for adjusting the spherical head screw) Loosen the screws and hold the gauge as shown in the illustration so that it is at a 90° angle to the handpiece. Turn the spherical head screw until the middle section of the gauge is at the same level as the outer section. Re- tighten the nut for the spherical head screw. (see Figure B)

Setting the locking ring for the adjusting nut (clamping nut):

When fitting the bolt return spring into the rotary sleeve, make sure that the large bend in the spring is arranged directly clockwise when looking at the handpiece from above. Place the spring over the rotary sleeve and insert the smaller, curved end into the hole. Make sure that the spring is correctly seated in the groove of the rotary sleeve.
Caution: The absence of the return spring leads to loss of tension and can also cause damage to the handpiece!

Removing the inner and outer joint pieces:
Remove the cap of the oil hole and insert a screwdriver through the hole to secure the eccentric shaft. Then loosen the gear wheels with a suitable spanner. You can then remove the inner and outer joints from the handle by hand.
Storage
Only store the shearing machine in dry spaces. Do not connect the shearing handle to a shearing drive if you suspect that liquid has entered the machine. There is a risk that some parts will be corroded and block the shearing handle. If you then try to use the shearing handle and switch on the shearing drive, serious injury may result. Get into the habit of storing the shearing handle when not in use, carefully cleaned, oiled, in a clean, dry room, out of the reach of children.
