Before operating the machine, anyone must read this description carefully and keep it well to ensure the equipment and operator’s safety, as well as others’ safety.

2.1 This machine is used to cut pipes made from PE, PP and PVDF and can not be used to cut no-description materials; otherwise the machine may be damaged or result in accident.

2.2 Don’t use the machine in a place with potential hazard of explosion

2.3The machine should be operated by responsible, qualified and trained personnel.

2.4The machine should be operated on a dry area. The protective measures should be adopted when it is used in rain or on wet ground.

2.5 The input power is within 380V±10%, 50 Hz. If extended input line is used, the line must have enough lead section.

2.6 Fill hydraulic oil (N46 ISO3448) into tank before the first time using. The oil volume should be about 2/3 of the tank.

3.2. Precautions for Safety

When operating the machine, instruction and safety rules should be abided carefully.

3.2.1 The operator should be trained and skillful personnel.

3.2.2 Completely inspect and maintain the machine per year for the safety and machine’s reliability.

3.2.3 Power: the electricity distribution box should have ground fault interrupter with relevant electricity safety standard.

Earthing: The whole site should share the same ground wire and the ground connection system should be finished and tested by professional people.

3.2.4 Storage of the machine:

For the min dangers all equipment must be operated as follows:

※ Do not touch electrophorus parts

※ Forbid hauling off the cable to disconnect

※ Do not put heavy or sharp object on the cables, and control the temperature of cable within limiting temperature (70℃)

※ Do not work in the wet environment. Check if the groove and shoes is dry.

※ Do not splash the machine

3.2.5 Check insulation condition of machine periodically

※ Check the insulation of cables specially the points extruded

※ Do not operate the machine under extreme condition.

※ Check if the ground fault interrupter works well at least per month.

※ Check the earthing of the machine by qualified personnel

3.2.6 Clean the machine carefully

※Do not use materials damaging the insulation easily (like gas, abrasive, and other solvents)

※The power should be disconnected when finishing job.

If only following above mentioned, the precaution can work well.


Any unexpected status occurs, please press “EMERGENCY STOP “immediately to stop the machine. After solving problems turn EMERGENCY STOP clockwise to start machine again.

3.2.8 Tightness of parts: Check if the pipes are fixed correctly and tightly. Make sure that it can not slide down to injury operator

3.2.9 Personnel safety while working

Remove jewelry and rings, and does not wear loose-fitting clothing avoid wearing shoe lace, long mustache or long hair that may be hooked into the machine.

3.2.10 Keep the site clean and tidy

Crowd, dirty and mussy site is not favourable to working, so it is important to keep the site clean and tidy.

3.2.11 Untrained person should never be allowed to operate the machine anytime.

3.3 Potential Dangers

3.3.1 Band saw

This machine is only operated by professional person or trained personnel, otherwise unwanted accident maybe caused.

3.3.2 Saw Blade

Never touch the running saw blade, or injury may cause

3.3.3 Cutting

Before cutting, clean the sand outside of the pipes or other draff crowed in the pipes when transporting. This can avoid unwanted damage of the saw blade or other accidents

6.1 Lifting and installation

6.1.1 If a forklift is used while installation, insert the fork carefully from the bottom of the machine to avoid damaging the oil hose or circuit.

6.1.2 When placing the machine, the machine should be kept stable and level by adjusting the level adjustor

6.1.3 This standard machine can cut angle 0~67.5°, if an angle within 45° is required, the 67.5° seat should be removed before working


7.1 Starting

7.1.1 Power the machine, and the power indicator must be on (if not on, the connection is wrong).

7.2 Testing of the saw box moving up and down by turning the feed speed adjustor on the right of operation panel.

7.3 Press the “jog clockwise” and “jog anticlockwise button “to check the running direction of the saw blade. If it rotates in the wrong direction, exchange connection between any two live wires linked to the power supply.

7.4 Cutting operation

7.4.1 Loosen the angle locking screw, push the saw blade box by hands to required angle (as per the required angle), and fasten the angle locking screw.

7.4.2 Raise saw blade box to a height (determined by the diameter of pipe to be cut) to ensure the saw tooth is above the pipes.

7.4.3 Put the cutting tubing on the work table, adjust the cutting position, and fix the pipe with nylon belt by locking device.

7.4.4 Start the saw blade, when the saw blade achieves specified speed (Running indicator will shine), turn the feed speed adjustor to fall the saw box slowly. The speed of falling should be regulated according to the pipe diameter and thickness.

7.4.5 When the cutting is going to be finished, please hold the pipe cut down to avoid blocking the saw blade.

7.4.6 Press emergency button if any abnormity occurs during cutting. After solving problems turn EMERGENCY STOP clockwise to start machine again..

7.4.7 Saw blade will stop automatically when it reaches lower limiting position

7.4. 8 When finishing the cutting Remove the cut pipe and recut.

7.4. 9 This standard machine can cut angle 0~67.5°, if an angle within 45° is required, the 67.5° seat should be removed before working on the pipes, shown as follows:

SDC315 Band saw Operation Manual (11)


1) Power the machine again in 30 minutes after cutting off the power to protect the converter.
