PRE-OPERATION CHECKLIST

STRAIGHTNESS OF CUT AND CONTROL WHEEL

The cut is affected by many factors, e.g. the size of thepipe, the material, the wall thickness, the quality of thepipe’s surface, the roundness, welded seams, bladecondition, feed rate, operator’s experience. For this reasonthe result may vary, and the cut may turn to left or right(misalignment of the cut’s starting and ending point).

The pipe saw gripper has one adjustablewheel which can be used for improving thequality of the cut and for reducing themisalignment.

The adjustment applies only to the actual pipe size andmaterial, and the wheel may have to be readjusted as theblade is worn.

The wheel can be adjusted in 9 positions; midposition and 4 steps to left and right. To adjustthe wheel, loosen the lockingscrew and turn the wheel centerclockwise or counterclockwise tothe desired position, and lock the

wheel again. If the blade has wandered toomuch to the right, adjust wheel center clockwise. It themisalignment is to the left, adjust counterclockwise.The number of steps depend on the actualmisalignment. Remember to lubricate the adjustingwheel at regular intervals.

AFTER CUTTING IS COMPLETE

When the pipe is cut off, push the UNLOCKbutton forward until the yellowmark is visible and the locking isreleased. Now raise the motor unitto starting position. Release thepower switch. When the blade isstationary, remove the pipe sawfrom the pipe by loosening thegripped handle. Ensure that themoving lower blade-guard is lowered intosafety position.

CHANGING THE SAW BLADE

Remove the power plug from the socket. Check that themotor unit is locked in the upper position.

Remove the blade guard cover by opening the two fingerscrews. Press the spindle-lock button andsimultaneously rotate the blade by handuntil the spindle-lock button drops afurther distance of about 7 mm. Now therotation of the blade is prevented. Use theblade key to open the blade attachmentbolt. Remove the securing bolt, thewasher, the blade flange disc, and theblade.Before installing a new blade, check that both bladeflange discs are clean. Place a new or sharpened bladeon the back flange disc, so that the marked side of theblade is facing outwards and the arrows on the blade arefacing in the same direction as the rotation directionmarkings on the inside of the blade case.Ensure that the new blade goes right to the bottom inthe back flange disc. Put the blade flange disc, thewasher, and the securing bolt back in place. Press thespindle lock button and tighten the blade securing bolt.Put the blade guard cover back in place and tighten thefinger bolts.

BEFORE CUTTING

Connect to the mains power supply, but before you do itmake sure that the mains voltage is the same as indicatedon the rating plate. Precise setting of the cutting point.When you mark the cutting point on thepipe to be cut, deduct 20 mm from therequired dimension.Use the system supports when cuttingpipes. This will ensure safe working andoptimum result. Work on flatunderground. Place the pipe on twosupports so that the cutting point is between the supports.Place two more support under both ends of the pipe.

Check that all support wheelcontact the pipe (adjust ifrequired e.g. with pieces oflumber).When cutting short pipes(25cm or less) place the

supports so that the cutting pointis outside the supports. Supportthe pipe with your leg, if required.Proper arrangements will preventthe blade from jamming as thepipe is cut through.

Attach the pipe saw to the pipe. To do itopen the pipe saw’s gripper unit enoughto suit the diameter of the pipe byrotating the adjustment handle located atthe rear of the saw.Position the pipe saw on top of the pipeso that the edge of the lower blade guard

is at the cutting mark. Fasten the pipe saw to the pipe byturning the gripper adjustment handle until the grippergrips firmly the pipe to be cut. Hold the pipe in place andensure that pipe saw moves freely in the direction the pipeis fed. For sake of safety ensure the pipe saw leads are to theleft of the pipe saw. The pipe saw is now ready for cutting.

CUTTING PROCESS

Pierce the pipe wall. Grip the gripperfirmly with your right hand and place yourleft foot on top of the pipe approximately50cm from the pipe saw. Turn the saw

until it leans slightlyforward. When startingthe motor, first of all release the power-switch locking lever and push thepower switch all the way down.

Before starting to saw, wait until theblade reaches full speed. Pierce thepipe wall by pressing pipe sawoperating handle downwards slowly andevenly until the blade has cut through thepipe wall (at this stage the pipe must notrotate) and the motor unit is locked in the sawing position.

Look at the UNLOCK button during thepiercing operation. When UNLOCK button islocked, i.e. the yellow mark disappears, pipesaw is locked in the sawing position, and youcan safely start sawing around the pipe.

Start sawing by feeding the pipe sawforward and fix the pipe with your leftfoot. 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, andfeed continuously forward ca. 1/6 ofthe pipe’s circumference. Repeat untilthe pipe is cut off.

NOTE: Select the sawing speed as per the material and thethickness of the wall. Too high speed can damage theblade, overload the pipe saw and give a poor sawing result.NOTE: Should there be problems during piercing or sawing,abnormal sounds or vibrations due to which you have tointerrupt sawing before the pipe is cut through, release theblade by pushing the UNLOCK button forward until theUNLOCK button is released, and lift the motor unit up. Oncethe problem is cleared, start sawing again.

OVERLOAD PROTECTION

The pipe saw is equipped with overloadprotection. When the blade is dull orthe speed is too high, the overloadprotection cuts power automatically.Restore the power by pushing theoverload protection switch.

WARNING!Never start the motor, when the motor unit is

locked in sawing position or teeth of the bladecontact the pipe to be sawn.
