Necessary equipment

  • Electric generator adapted to the voltage of the unit (220 - 240 V / 50 - 60 Hz)
  • Extension cord
  • Gloves
  • Glasses
  • Cloth
  • File
  • Knife

Before operating the tool

  • Ensure that the motor unit is in the upright position. The yellow mark of the UNLOCK button is visible.
  • Check that the blade is correctly fitted, in good condition and suitable for the material to be cut.
  • Ensure the pipe saw guide wheels rotate.
  • Ensure the support wheels rotate.
  • Check the operation of the lower blade guard.

Setting the pipe on supports

Use the system supports when cutting pipes. This will ensure safe working and optimum result. Work on flat surface. Place the pipe on two supports so that the cutting point is between the supports. Place two more support under both ends of the pipe. Check that all support wheel contact the pipe (adjust if required e.g. with pieces of lumber) (Figure B).

When cutting short pipes (25 cm or less) place the supports so that the cutting point is outside supports (Figure D). Support the pipe with your left leg, if required. Proper arrangements will prevent the blade from jamming as the pipe is cut through.

Adjustment

There is an adjustment lever in the gripping unit of the saw for to pre-set the correct depth for the bevel [18].

  • Position A : DN 75, DN 90
  • Position B : DN 110
  • Position C : DN 125, DN 140 and DN 160

A cutting speed adjustment (1-6) is proposed. For optimum operation on Blutop and Topaz, the recommended setting is 6.

Operation

  • 1- Open the pipe saw's gripper unit enough to suit the diameter of the pipe by rotating the adjustment handle located at the rear of the saw (Fig. E). For sake of safety ensure the pipe saw leads are to the left of the pipe saw.
  • 2- Grip the gripper firmly with your right hand and place your left foot on top of the pipe approximately 40 cm from the pipe saw. Turn the saw until it leans slightly forward (Figure H). When starting the motor, first of all release the power-switch locking lever (Fig. F/1) and push the power switch all the way down (Fig. F/2). Before starting to saw, wait until the blade reaches full speed. Pierce the pipe wall by pressing pipe saw operating handle downwards slowly and evenly until the blade has cut through the pipe wall (at this stage the pipe must not rotate) and the motor unit is locked in the sawing position (Fig. H/1). Look at the UNLOCK button during the piercing operation. When UNLOCK button is locked, i.e. the yellow mark disappears (Fig. G), pipe saw is locked in the sawing position, and you can safely start sawing around the pipe. Stop pressing when the yellow mark Unlock disappears (Fig. G/2)
  • 3- Start sawing by feeding the pipe saw forward and fix the pipe with your left foot (Fig. H/3). After that release the pipe (remove your left foot from the pipe) and turn the pipe saw backwards, whereby the pipe will also be rotated backwards. Start a new feeding movement, and feed continuously forward ca. 1/6 of the pipe's circumference. Repeat until the pipe is cut off. When the pipe is cut off, push the UNLOCK button forward until the yellow mark is visible and the locking is released. Now raise the motor unit to starting position. Release the power switch. When the blade is stationary, remove the pipe saw from the pipe by loosening the gripped handle. Ensure that the moving lower bladeguard is lowered into safety position.

Straightness of cut

The cut is affected by many factors, e.g. the size of the pipe, the material, the wall thickness, the quality of the pipe's surface, the roundness, welded seams, blade condition, feed rate, operator's experience. For this reason the result may vary, and the cut may turn to left or right (misalignment of the cut's starting and ending point) (Fig. M). The pipe saw gripper has one adjustable wheel [9] which be used for improving the quality of the cut and for reducing the misalignment. The adjustment applies only to the actual pipe size and material, and the wheel may have to be readjusted as the blade is worn. To adjust the wheel, loosen the locking screw (Fig. N/1) and turn the wheel centre clockwise or counter clockwise to the desired position (Fig. N/2), and lock the wheel again (Fig. N/3). If the blade has wandered too much to the left, adjust wheel centre clockwise (- sign). If the misalignment is to the right, adjust counter clockwise (+ sign). The extent of the adjustment depends on the actual misalignment. Remember to lubricate the adjusting wheel at regular intervals.

Changing the disc

  • 1- Remove the power plug from the socket. Check that the motor unit is locked in the upper position. Remove the blade guard cover (Fig. O/1) by opening the two screws (Fig. O/2). Press the spindle-lock button [11] and simultaneously rotate the blade by hand until the spindle-lock button drops a further distance of about 0,2”. Now the rotation of the blade is prevented. Use the blade key to open the blade attachment bolt. Remove the securing bolt (Fig. O/3), the washer (Fig. O/4), the blade flange disc (Fig. O/5), and the blade (Fig.O/6).
  • 2- Before installing a new blade, check that both blade flange discs are clean. Place a new or sharpened blade on the back flange disc (Fig. O/7), so that the marked side of the blade is facing outwards and the arrows on the blade are facing in the same direction as the rotation direction markings on the inside of the blade case. Ensure that the new blade goes right to the bottom in the back flange disc. Put the blade flange disc, the washer, and the securing bolt back in place. Press the spindle lock button and tighten the blade securing bolt. Put the blade guard cover back in place and tighten the bolts. Important: use only Exact Diamond discs for this bluCut pipesaw. BluCut System can be used for cut or cut and beveling Blutop® and Topaz® cast iron pipes and certain plastic pipes Do not use it with other materials!
