1 M95 Pipe Shaver for Taper/Taper adhesive-bonded Pipe Joints in sizes 24 to 40 inch ( mm) Introduction The Bondstrand M95 Pipe Shaver is designed to prepare a tapered spigot on the cut end of a Bondstrand pipe in 24 to 40 inch (600 to 1000 mm) pipe diameter to fit a Bondstrand fitting with a matching tapered socket and prepare cylindrical pipe ends for mechanical couplings such as Helden, Straub TM, Viking Johnson TM, Dresser, etc. Due to the fact that the traditional cutting tool has been replaced by a diamond coated grinding drum, the preparation time for a spigot has been reduced significantly. To eliminate the dust and to increase the life cycle of the grinding drum, the shaving tool is equipped with a water spray system. This system provides a water supply on the grinding drum during operation. The shaver is fixed and centered on the end of the pipe by an expanding arbor. The arbor is inserted in the pipe end and provides the required grip when the arbor contraction bolts are tightened. Arbors are available in sizes 24 to 40 inch (600 to 1000 mm) The shaving tool is powered by means of two permanently fixed electric motors, one for rotating the arbor (normal procedure) and one for driving the grinding drum. In this case, the shaving tool also can be used to shave spigots on an existing pipe system. In this case the shaver has to be fitted with the (optional) counterbalance weights. Each M95 shaving tool is supplied in a case including one collapsible workshop crane, one adjustable spreader bar, two adjustable pipe supports with rollers. These tools are required to operate the shaving tool. Counterbalance weight and arbors are not included and should be ordered separately. Note: The use of this shaving tool is restricted to Bondstrand pipe material. EG-STATEMENT OF AGREEMENT According to machinery directive 98/37/EG, appendix II, under a, this shaver * complies with machinery directive 98/37/EG; * complies with the following harmonised European Standards: NEN-EN 1050, NEN-EN and NEN-EN M95 Pipe Shaver

2 Safety precautions Personal protection and safety The following personal protection gear must be used when cutting, shaving, sanding and grinding GRE material: Safety shoes or boots; Work gloves (GRE material can be very sharp and may cause cuts or splinters); Proper fitting and buttoned up protective clothing must be worn when operating the shaver; A hard hat is to be used, if the situation requires so; A hair net must be worn, if applicable, when shaving, cutting, grinding, etc; An appropriate dust mask is to be used when cutting, shaving, grinding and sanding. Operational safety For safe operation of the shaving tool, the following rules must be followed: Pipe-shaver assembly must be at ergonomic height to be able to work in the proper posture; Only use the shaving tool i.e. workshop crane on a solid and levelled surface or floor; Ample rest should be taken to avoid excess physical or mental stress; Only authorised persons are to be allowed in the shaving area; Shaving area must be clearly marked as such; Shaving tool shall only be used to prepare spigots on Bondstrand pipe material; Pipe shaver shall only be operated by trained persons; Shaving tool must be kept in good working order to guarantee proper and safe operation. Defect parts must be replaced or repaired by qualified personnel only. Note: The noise level of the shaver and power drive is less than 70 db (A). The following procedure should be carefully followed to ensure satisfactory operation of the shaver. 2

3 Operating instructions 1. FITTING THE PIPE SUPPORTS Assemble the two pipe supports with the rollers (Photo 1). Position the rollers in such a way that the pipe, when placed on the support, is running free from the support frame. Adjust the distance between the two supports in such a way, that the pipe section to be shaved gets maximum support. Make sure that the supports are parallel. Photo 1 Place the pipe section on the supports (Photo 2). Photo 2 2. FITTING THE ARBOR A. Check that the pipe is cut square and correct if necessary. Squareness shall be within 0.5% of the pipe diameter. For example: if the pipe diameter is 900 mm, the allowable unsquareness is 4.5 mm. B. Make sure that the pipe is clean inside and there are no loose fibers inside the pipe. C. Insert the arbor and ensure the arbor butts up against the pipe end. D. Tighten the expansion bolts with a suitable spanner (Photo 3). Photo 3 3. FITTING THE SHAVING TOOL Lift the shaver using the supplied workshop crane and spreader bar (Photo 4). Shift the spreader bar lifting hook until shaving tool is horizontal. Note: During lifting and handling the shaving tool must be disconnected from power source to avoid accidental start of equipment. Photo 4 3

4 Position the shaving tool with the 4 stub-bolts on the arbor hub and put the nuts in place (Photos 5 and 6). Tighten the nuts. Lower the workshop crane until there is only a slight tension left in the spreader bar chains. Most of the weight must rest on the two supports. Do not remove the workshop crane! Photo 5 Photo 6 4. ADJUST THE SHAVING TOOL Move the grinding drum away from the center shaft using the crank. To set the shaving angle, remove the two locking bolts, push the grinding drum towards the center shaft, and turn the angle setting disk to obtain the desired angle setting (Photo 7). Photo 7 Replace and tighten the locking bolts (Photo 8). The required shaving angle can be found in this manual (Table 2 Shaving dimensions, page 8). Photo 8 Move the grinding drum towards the pipe until it is just running free from the pipe wall (Photo 9). Photo 9 Photo HOOK UP OF THE WATER AND POWER SUPPLY Connect the water supply to the spray tube connection. Connect the shaving tool with the control box (Photo 10). Before connecting the shaving tool control box to the power supply, activate the emergency stop button. After connecting to the power supply deactivate the emergency stop button. Check that the whole pipe and shaver assembly is stable and that the pipe can rotate freely. Make sure that the power cables and water supply hose are not entangled and run free from the shaving tool. 4

5 6. GRINDING THE SPIGOT Open the water supply valve and adjust so that there is a liberal flow of water coming from the water nozzles (Photo 11). Photo 11 Start the grinding drum. Start the rotation motor. (Photo 12) Photo 12 Move the grinding drum slowly towards the pipe. Move the grinding drum slowly towards the pipe after each cutting depth is completed (Photo 13). Photo 13 Do not exceed the following cutting depth steps: 1 mm for total grinding length of 100 mm. 0.5 mm for total grinding length from 100 to 200 mm. and 0.25 mm for total grinding length above 200 mm. Avoid fast cutting depth changes and never do this when either rotation motor or grinding drum motor is not running. Consult the shaving dimension Table 1 in the manual for the required nose thickness. When the required shaving dimension is obtained, allow the shaving tool to make 2 final revolutions while grinding drum is running. This to obtain a smooth spigot surface. Stop the grinding drum motor and move the grinding drum away from the pipe after the grinding drum has come to a complete standstill. Stop the rotation motor and close the water supply valve. Remove the shaver and arbor from the pipe. When the shaving tool is not used or moved, it is recommended to lower the shaving tool onto a wooden pallet or board which is placed on the crane outriggers (Photo 14). Photo 14 5

6 7. GRINDING A SPIGOT ON A FIXED PIPE In situations where a spigot has to be shaved on an existing system and the pipe cannot rotate, the procedure will be as follows. Fit the arbor and shaver as described above and remove the workshop crane. Attach the counterbalance weight rod to the shaver frame by means of the 4 supplied bolts. Put the inner locking pin in the position. Place the required number of counter weights on the rod (Photo 15). Photo 15 Secure the weights by means of the outer locking pin and use the safety pin to secure the locking pin (Photo 16). The number of counter weights to be used depends on the pipe diameter to be shaved. For larger pipe sizes the counter weight mass needs to be more in order to out balance the shaving tool. Check that the shaving tool can rotate freely. Start the arbor motor and check that the shaving tool is in balance. Photo 16 Open the water supply valve and adjust such that there is a liberal flow of water coming from the water nozzles. Start the grinding drum. Start the rotation motor. Move the grinding drum slowly towards the pipe. Move the grinding drum slowly towards the pipe after each cutting depth is completed. This can be done while the shaver is rotating or during an intermediate stop of the rotation motor. During the rotation of the shaving tool, the power cables will twist. Untwist cables repeatedly, as necessary. Note: Please avoid fast cutting depth changes and always make sure that both the rotation motor and grinding drum are running! Consult the Shaving Dimension table in the manual for the required nose thickness. When the required shaving dimension is obtained, allow the shaving tool to make 2 final revolutions while the grinding drum is running. This is to obtain a smooth spigot surface. Stop the grinding drum motor and move the grinding drum away from the pipe after the grinding drum has come to a complete standstill. Stop the rotation motor and close the water supply valve. Remove the shaver and arbor from the pipe after removal of the counterbalance weights. 6
