INTRODUCTION

The Nexus shearing set is a mains operated machine with three speed settings. Standard pulleys give 2800, 3200 & 3500 RPM. The optional “Lo-Range” pulley set gives speeds of 2000, 2800 & 3500 RPM. The fastest speed setting is on the lower grooves (i.e. next to the top plate). The drive belt is automatically tensioned correctly by a compression spring, and will not require adjustment.

The machine is operated by a pull switch, pull once for on, pull again to switch off. Before connecting your drive, ensure the motor is in the off position. Drive connection is ex-plained later.

Make sure to read and understand the instruction book supplied with your handpiece. Always have a good supply of sharp, clean combs and cutters when shearing, and change them when necessary. With proper care, maintenance and lubrication your Nexus set should give years of trouble free shearing.

GETTING STARTED / SETTING UP

CONNECTING A STANDARD FLEXIBLE DRIVE (Fig.1a)

1. Slacken top sleeve nuts and expose the bayonet joint attached to the inner.2. Push bayonet joint onto the machine drive spindle against the spring. Hold the drive

spindle still and rotate the bayonet joint so that the drive spindle pin engages into the L-shaped slot in the bayonet joint.

3. Push the top sleeve right up over the spindle bearing and tighten the top nut.4. With the drive hanging straight, adjust the flexible outer up or down until the bottom

joint projects through the end ferrule by about 20mm (3/4”) as shown in Figure 3. Tighten the lower top sleeve nut.

CONNECTING A QUICK RELEASE FLEXIBLE DRIVE (Fig.1b)

1. Open the quick release clamp and push the top sleeve right up over the spindle bear-ing until it hits the end stop. Twist it as it goes up if necessary to encourage the spline drive spindle to engage with the quick release joint.

2. Close the quick release clamp and check that the drive is hanging securely. If it is not secure, re-open the clamp and tighten the adjusting nut to increase the clamping force before closing the clamp again. Repeat as necessary.

3. The sheath assembly position is preset so that the top end of the sheath assembly is 118mm (4 5/8”) from the top end of the top sleeve. This ensures that the spline drive spindle engages correctly with the quick release joint and causes the bottom joint to project from the end ferrule by about 20mm (3/4”) as in Fig. 3.

3

WORKING HEIGHT - FLEXIBLE DRIVE (Fig.2)

The set should be suspended, with the flexible drive hanging straight down, so there is 25mm (1”) between the end of the flexible drive inner and the floor or work-ing area. To make sure there is no undue strain on the mains lead or flexible drive, the machine should be se-curely fixed to a wall, beam or shearing trailer to prevent it rotating when operating the pull switch.

CONNECTING & DISCONNECTING THE HANDPIECE

Set the comb and cutter as explained in the handpiece instruction book, and tension cor-rectly. Screw the ferrule onto the backjoint tightly. Holding the handpiece in one hand and the end of the drive in the other, insert the drive into the ferrule. Press the handpiece firmly onto the drive and rotate the handpiece clockwise to engage the drive pin (or worm drive). Make sure there is enough tension on the handpiece to prevent the cutter moving easily during engagement.

To remove handpiece from the drive, switch off the machine. Push the handpiece onto drive and, maintaining pressure, rotate anti-clockwise until pin (or worm drive) is disen-gaged. Handpiece will now disconnect.

SOLID DRIVE

ASSEMBLY OF SOLID DRIVE (Fig.4a)1. Slide ferrule onto bottom (plain) end of the long tube.2. Hook the tube joint assembly, (either spindle eye) onto the hook at the bottom end of

the long inner core (inside the long tube).3. Slide the ferrule down the long tube and screw onto the threaded end of the tube

joint assembly. Tighten securely.4. Hook the other end of the tube joint assembly onto the short inner core.5. Slide the short tube over the short inner core and tighten the nut onto the tube joint

assembly so that the end of the bayonet joint protrudes 3mm (1/8”).

CONNECTING A STANDARD SOLID DRIVE (Fig.4b)1. Slacken top sleeve nuts. Push exposed bayonet joint onto the machine drive spindle

against the spring. Hold the drive spindle still and rotate the bayonet joint so that the drive spindle pin engages into the L-shaped slot in the bayonet joint.

2. Push the top sleeve right up over the spindle bearing and tighten the top nut.3. Slide the long tube/spring assembly up inside the top sleeve until approx 216mm

(8½”) of spring is exposed, then tighten the lower top sleeve nut. This ensures correct clearance at the end of the long tube inside the ferrule.

CONNECTING A QUICK RELEASE SOLID DRIVE (Fig.4c)1. Open the quick release clamp and push the top sleeve right up over the spindle bear-

ing until it hits the end stop. Twist it as it goes up if necessary to encourage the spline drive spindle to engage with the quick release joint.

2. Close the quick release clamp and check that the drive is hanging securely. If it is not secure, re-open the clamp and tighten the adjusting nut to increase the clamping force before closing the clamp again. Repeat as necessary.

3. The tube spring position is preset so that the top end of the top spring is4. 118mm (4 5/8”) from the top end of the top sleeve. This ensures that the spline drive

spindle engages correctly with the quick release joint and ensures correct clearance at the end of the long tube inside the ferrule.

WORKING HEIGHT - SOLID DRIVE (Fig5.)

With the handpiece removed, the set should be suspended so that when the solid drive hangs down freely, there is just 1mm between the end of the drive joint and the working surface. The machine should be securely & rigidly fixed to a wall, beam or shearing trailer so that it does not move during operation. This allows the tube spring to function properly.

‘SENSOR’ OVERLOAD CUT-OUT

The NEXUS SENSOR and NEXUS PRO SENSOR are fitted with an automatic cut-out which will operate if an overload situation arises. This ‘Sensor’ will automatically switch off the power to the motor, and the handpiece may also disconnect. This is normal. If this happens, check the handpiece and comb & cutter for faults or obstructions before resum-ing shearing. The pull switch will need to be pulled once to reset the Sensor and a second time to restart the motor.

Note: Under certain circumstances, when an obstruction is hit, the drive may disengage from the machine before the Sensor cut-out can operate. This is normal and does not signify a faulty Sensor.

Fig. 5

CHANGING SPEED (Fig.6)

1. Remove top cover screws and top cover with allen key provided.2. Move the drive belt to the required position by pushing the spindle bearing towards

the motor to reduce belt tension, then move the belt to required grooves.3. Ensure the belt is correctly positioned in both pulley grooves to eliminate belt/pulley

wear.4. Replace top cover and screws.

Fig. 6

7

MAINTENANCE & LUBRICATION (Fig. 7)

The NEXUS, when properly cared for, should give years of trouble-free shearing. To keep machine and drive in the best possible condition, follow these simple instructions:

1. Make sure machine is fixed securely when shearing to prevent strain on the electric cable.

2. Keep air vents clear form blockages.3. Ensure the drive spindle is regularly oiled through the oil hole in the spindle bearing

during shearing. DO NOT over-oil as this can lead to oil getting onto the drive belt and causing slip and loss of drive.

4. Periodically check the pulley drive belt for signs of wear, and change if required. Make sure the top plate is clean and free from oil. A worn or oily belt can make the pulleys “slip”.

5. When shearing make sure the flexible or solid drive is regularly oiled at all the correct places (See Fig.7).

6. When not shearing, store flexible drives straight or with minimum bending. Flexible inners should be lightly greased and solid cores oiled at the end of the season before storing.
