Welcome

The

Tailwell™

tail trimmer was developed in New Zealand to simplify the tedious job

of trimming tails of milking cows. Tail trimming is carried out to reduce faecal and

urine contamination of the milker, and to reduce dirt around the rear quarters and

udder of the cow. It is recommended that tail trimming is carried out twice per year

to ensure milker safety and highest milk quality.

The

Tailwell™

power tail trimmer is secured by way of the

chuck shank into any suitable cordless drill of 14 volts

or better, and operating at approx 1,000rpm.

Tailwell™

is quiet in use, with a smooth and fast cutting action.

Trimming takes only 3 or 4 seconds per tail, and is easily

accomplished during milking. The outer blade oscillates

over a stationary inner blade, so there is no risk of injury

to the cow. Even dirty dag-ends feed smoothly over the

trimmer. Pre-cutting the tail’s switch is not necessary.

This is a sturdy precision tool that will withstand

considerable use. A neck strap is incorporated so the

device can be hands-free between cows. Replacement

blade sets are available.

The blades must be well lubricated.

Pre-cutting of the tail switch is not necessary,

even if it is very dirty. A trimming collection

apron is available as an accessory and is useful

to prevent trimmings blocking pit drainage.

Tail Trimming Apron (accessory)

A recommended accessory for the

Tailwell™

is our specially

designed apron. This garment incorporates a large bag

with rigid plastic hooks which are hung on the pit rail

where they can easily be slid along cow-to-cow. (The hooks

are suitable for rails up to 50mm diameter.) When the

bag needs emptying, the wearer simply steps out to the

required place and pulls the Velcro bag attachment apart,

letting the trimmings fall out. Bag will hold 50-100 tail

trimmings.

Drill Choice

The recommended power drill is a standard 14-volt battery unit with an operating speed of

up to 1,250 rpm. (Higher cutting speeds do not work better, and may damage the cutters,

and will void any warranty.) A lightweight drill is easiest to use, and is recommended. A

good quality drill battery should allow trimming of 80-100 tails per charge.

Attaching to your Drill

To attach the Tailwell™ to your drill, you must loosen the drill chuck so that the trimmer

drive shaft fits fully into the chuck, then tighten the chuck. The neck strap is designed for

the drill chuck to fit through (see photo 1). This strap gives comfortable balance for the

unit to hang from your neck, and allows work hands-free between tails.

Torque Arm

The fingers of the torque fork are designed to straddle the drill body to prevent the

Tailwell™ rotating about the drill (see photo 1).

Lubrication

Important: Before operating this machine, the cutters and gear set must be well-oiled

using the oil supplied, or ordinary engine oil.

There is an oil hole in the side of the plastic gear set cover. Squirt 3 or 4 drops into this

hole while the unit is running (photo 2), and also add 3 or 4 drops around the cutters

(photo 3 & 4). This should be repeated every 50 tails, or more frequently if the tails are

wet and dirty. An alternative method of oiling is to dip the cutter head frequently into

a small bowl of oil, but seperate frequent lubrication will still be required in the gear set.

The warranty is void if the tail trimmer has not been properly lubricated.

Safety

The inner cutter does not move, so cannot cut the animal. The outer cutter oscillates

through only 18 degrees, so is also safe. The tail is fed into the cutters, and pulled

through as required. Operate the drill at a suitable speed (up to 1,250 rpm) to ensure

clean cutting.

Cutter Adjustment

Before adjusting - clean and lubricate the cutters.

There are two cutter-adjustment screws on the back-plate of the cutter housing. These

screws have lock nuts that must be loosened a couple of turns (photo 5). The adjustment

screws are then screwed in by hand, finger tight only (photo 6). Do not tighten these

screws with an Allen key as this will cause cutter and gear failure, voiding the warranty.

The lock nuts are then tightened with a spanner. Lubricate the cutters before use.

Tips

Do not force the cutter. Let it do the work, especially if tails are heavily dagged. Let the

cutter chew slowly through badly matted hair. In worst cases, dags may have to be pulled

apart to enable the cutter to work. If cutting is not even all around, the cutter tension

screws may need adjusting.

Storage

It is imperative to carefully clean and thoroughly relubricate the gears and blade set,

prior to storage in a clean and dry environment. The blades are manufactured from high

quality tool steel but will rust and potentially seize if not stored well lubricated. To do

this correctly the blade set must be removed (following our instructions supplied) and

packed with grease between inner and outer blades, and also around the gear set. Blades

and gears should also be checked for wear at this time. Reassemble and check all body

screws for tightness.

Operating Instructions

Blade Set Sharpening Instructions

Warranty - IMPORTANT

Depending on the conditions of use, but generally after somewhere between 500 and 1,000

tails, your Tailwell™ blade set may need sharpening. This can be done by a professional

clipper blade sharpening service, or by following the instructions below.

Remove the cutter head backing plate (part 7), by unscrewing the four Allen-head1. screws. The inner cutter can then be removed (see photo 1)

The outer cutter can then be sharpened in-place (see photo 2) by filing two teeth at a2. time. To do this at the correct angle keep seven teeth to the right of the file. File on the

left side. This will give the correct cutting edge bevel. Work all the way around the cutter

to sharpen all the edges of all the teeth.

With the inner cutter removed from the cutter head, file two teeth at a time (see photo3. 3) keeping ten teeth (half the teeth) to the right of the file. File on the left or right side.

This will give the correct cutting edge bevel. Work all the way around the cutter to

sharpen all the edges of all the teeth.

Carefully clean all filings from both cutters, lubricate, and reassemble ensuring inner4. cutter key (part 6) is correctly in place. Reattach the cutter head backing plate (part 7)

but only after first backing-off slightly the two cutter tension adjusting screws (part 19).

After reassembly, the cutter tension adjusting screws (part 19) must be reset, using5. fingers only, to give the correct and evenly-balanced pressure on the cutters (see photo

4). The tension screws lock nuts should then be gently tightened with a spanner (see

photo 5). Your Tailwell™ should then be ready for relubrication and use.

The Tailwell™ warranty is against any faulty manufacturing, materials or workmanship. It

is not a warranty against failures involving normal wear and tear, or failures occurring from

normal farmer use. It does not cover failures caused by inadequate lubrication, servicing

or maintenance, and does not cover failure caused by use on a non-recommended power

drill. The warranty is void if the machine is used for contracting work, excepting in the

case of failure caused by faulty manufacture or parts. Sales agents for the tail trimmer are

not authorised to replace a failed machine, even if the device is near new, or is required

urgently for use. The manufacturer will repair or replace parts at its own discretion. Any

parts or repairs will be considered part of the original product in regard to their warranty.

The warranty is for a period of six months from date of purchase. Proof of purchase will be

required for any warranty claim.

Removal of Blade for Service or Cleaning

From time to time, depending on the conditions of use, the blade set will need to be removed

from the cutter head for cleaning. Any build up of dirt or grime around the outer cutter, will

affect the machine’s performance.

Remove the gear set cover (part 4).1. Remove the conrod pin split pin (see photo 1) and then lift out the conrod pin (see2. photo 2).

Swing back the conrod (part 16). The cutter set drive pin can then be unscrewed (see3. photo 3) and removed.

Remove the cutter head backing plate (4 screws), but only after first backing-off4. slightly the two cutter tension adjusting screws (part 19).

The cutter blades can then both be removed (photo 4). Wash blades and cutter head5. housing thoroughly with kerosene or similar. Check for any dirt build up inside the

cutter head.

Apply a liberal coating of oil or grease to the cutter blades and replace into the head.6. Take care to align the thead hole on the outer cutter with the slot in the cutter head.

Re-insert the cutter drive pin, leaving the head aligned to fit the conrod. Re-attach the

conrod and re-insert conrod pin and split pin.

The cutter tension adjusting screws (part 19) will now need resetting, using fingers7. only, to give the correct and evenly-balanced pressure on the cutters (photo 5). The

tension screws lock nuts should then be gently tightened with a spanner (see photo 6).

Your Tailwell™ should then be ready for lubrication and use.

How to fit the Torque Arm Extender

On some power drills the

Tailwell™

torque arms may be too short to prevent

rotation of the machine. In these cases the nylon Torque Arm Extender tube should

be used.

Fit the

Tailwell™

to your drill and adjust the torque arm position to give good access

to the drill trigger. You can make this adjustment by bending the arm up or down

and opening or closing the ﬁngers to suit your drill.

The nylon tube is pushed over one of the ﬁngers all the way to the end, and then

wrapped around the back of the drill grip, and pushed onto the other ﬁnger. Cut

any excess tube with a knife if neccessary. (Putting the nylon tube in hot water for

a few moments will help the ﬁtting.)

The nylon tube will protect the drill from chaﬁng on the torque arm and help to

prevent the drill from accidental disconnection from the tail trimmer and falling to

the ground.
