DO NOT!

• Attempt to work on the machine with it connected to the main power supply.
• Attempt to clip a wet or perspiring animal.
• Touch the blades when moving!
• Switch the machine on with loose or missing blades. (In the interests of safety ensure that both blades are tightly seated.)
• Fit blades with the tension knob in “tension.” Slacken off first.
• Over tighten the blades in an attempt to force them to clip.
• Use if the voltage at your site is different to that on the clipper rating plate.
• Attempt to dis-assemble the blades or any part of the clipper over straw, shavings or other materials. Only carry out such tasks on a specified area i.e. table or work bench otherwise essential parts may be lost.
• Immerse either the machine or cutter head in liquid (oil/diesel/lubricant) of any kind.

Fitting the blades:

Ensure the machine is disconnect from the power supply

Make sure both blades to be used are clean with no dirt or hair present on the cutting surfaces. Before fitting your blades loosen the tension knob (Fig 1) and remove any existing blades present by unscrewing the two blade nuts on the underside of the clipper head. It is most important to loosen the tension knob also otherwise it can affect the correct tensioning later and the resulting success of the clip. Apply oil to the underside of the upper blade (cutter) and especially in the oiling point (Fig 2) (failure to do this can result in possible overheating!)

Now turn the machine 180 degrees for a comfortable working position.

You will notice that the oscillator head (Fig 3) has two “nibs” protruding upwards. The cutter blade (the smaller of the two blades) is positioned “seated” on these “nibs” which holds it in position when the machine is in operation. The cutter blade should be placed on the “nibs” so that you see the inside of the blade. (Obvious - but we have known them put the wrong way round!) Place the comb (larger blade) on top of the cutter sliding it back under the two blade screws - You should be able to read the Manufacturer’s details on the face of the blade.

Finally lightly hand tighten both the blade screws sufficient to hold the blades in place. Rotate the machine to the upright position and check the setting of both blades to be sure they are correctly positioned. It is important that the cutter (top blade) is set back between 1/32nd to 1/16th of an inch 0.8mm - 1.6mm) from the ridge on the Comb.(bottom blade) (Fig 4) Once satisfied that this is correctly positioned you can fully tighten both blade screws.

Tensioning the blades:

To adjust the tension turn the tension knob (Fig 1) counter clockwise until resistance is felt. Do not force the knob against the resistance. Rotate the knob clockwise until light resistance is felt, continue turning about one half turn. When the tension knob cannot be turned any further it is usually an indication that the blades need re-sharpening.

Before staring to clip you should test the machine to ensure you have the blades correctly fitted and that they are secure. Before connecting to your power supply and switching on the appliance first apply oil to the oiling point and between the blades. When running the machine on test the machine should be pointed away from you and/or any animal for safety.

If for some reason the machine fails to clip smoothly it is highly likely you have not correctly adjusted the tensioning. Adjustment should be in small amounts. Increase/decrease the tension nut by no more than ¼ turns (or less) at a time to achieve optimum cutting. In most cases failure to clip correctly is operator orientated rather than a fault with the machine. Practice is valuable!

You may need to adjust the tension during the clip - this has nothing to do with any fault on the part of the clipper, rather a change in texture of the coat being clipped. (Sheep folk do it all the time!)

Avoid setting the pressure on the cutter plate too high as this will lead to excessive heat build up and will rapidly cause the blades overheat and become blunt. Keep blades well oiled. Do please remember blades can go blunt at a moment’s notice due to high levels of dirt and grit with the animal’s coat especially in the case of horses during the first clip of the season. In the case of even the best groomed cattle or horses unless they have previously been wash there is likely to be a considerable build up of particles of grit and dust which can cause blade failure (on any type of blades!) very quickly.

Oiling:

Oiling of the blades should be carried out at regular intervals during the clipping application.

It is most important to ensure that the cutter (upper plate) and the comb (lower plate) are kept constantly oiled and not allowed to dry out as this will lead to overheating of the blades, which will quickly impair the cutting performance.

Use only light machine oil of good quality. Do not use sewing machine oil, bone or other oil. DO NOT use WD40 ever!

Routine Maintenance:

Servicing

Regular servicing is advisable especially if the machine is worked hard. This is best carried out by a qualified engineer.

Air Filter

The Air Filter (Fig 6) must be kept clean and free of hair and dirt at all times. The perforations of the filter should be regularly cleaned and if badly blocked can often be successfully cleaned using a stiff toothbrush. The Air filter on the “Clipmaster” is one of the most difficult we have come across to remove!

Eccentric (Drive) Block

Known also as the “drive block” (Fig 5) Always check when changing the blades to see if there is any undue wear. (Fig 5b) The block can be easily removed for this purpose. This is done by raising the Oscillator cradle upwards (Fig 5a). Be careful to do this away from straw and other bedding material as the block may fall out during the operation. Replacing the Oscillator cradle over the block can prove difficult as the drive block easily moves. The trick is to hold it “square” and positioned with the aid of a small screwdriver (Fig 5c), As a safety measure when not fitted with blades wrap a broad elastic band round the head to stop the Oscillator cradle dropping down and thus releasing the block

Cable lead

Should be check regularly for cuts or other signs of damage (Hooves with shoes can inflict cable damage.)

Cutter head

Should be cleaned each time after use.. Remove both blades. Using a soft brush clean thoroughly both the head and all components parts, after which wipe clean with a dry cloth. Reassemble the blades carefully and oil.

Storage: When not in use, having been thoroughly cleaned and oiled, the machine should be stored in a dry place preferably in your house. Do not leave in tack rooms, stables, cow barn, dairy shed, lorries, or outside!

The same should apply to all blades.
