Noise/Vibration Information
Measured values determined according to EN60745.
Wear hearing protection!
Vibration total values (triax vector sum) determined according to EN60745:
Vibration emission value ah =2,84 m/s2, UncertaintyK =1.5 m/s2.
The vibration emission level given in this information sheet has been measured in accordance with
a standardised test given in EN 60745 and may be used to compare one tool with another. It may be
used for a preliminary assessment of exposure.
WARNING: The declared vibration emission level represents the main applications of the tool.
However if the tool is used for different applications, with different accessories or poorly
maintained, the vibration emission may differ. This may significantly increase the exposure level over
the total working period.
An estimation of the level of exposure to vibration should also take into account the times when the
tool is switched off or when it is running but not actually doing the job. This may significantly reduce
the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration such as:
maintain the tool and the accessories, keep the hands warm, organisation of work patterns.

operating instructions
Fig B
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
- Ensure the pipe is empty.
- Check the position of chip removal lever.
The pipe saw is equipped with a nozzle for
removing chips. When sawing plastic pipes, turn
the chip removal lever (Fig A/10) to "open" position
(Fig B), which opens the hatch in the blade
housing. If you attach a vacuum cleaner to the
chip removal nozzle, most of the plastic chips will
then fly out of the chip removal nozzle (Fig A/11)
and won't remain inside the blade housing. When
sawing metal pipes, turn the lever to "close"
position (Fig B). The metal chips will drop out from
the bottom of the blade housing. Never attach
a vacuum cleaner when cutting metal pipes.
Connection to the mains power supply
Ensure that the mains voltage is the same as
indicated on the rating plate (Fig A/14). Connect
the pipe saw to the power outlet only after
having checked this.
Precise setting of the cutting point
When you mark the cutting point on the pipe to be
cut, deduct 20 mm from the required dimension
(Easy-to-remember rule: The cutting mark location
requires a measurement of - 20 mm.) (Fig C)
Fig C
Cutting point
Cutting mark
Fig D
Fig E
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) (Fig D). When cutting
short pipes (25 cm or less) place the supports so
that the cutting point is outside supports (Fig E).
Support the pipe with your left leg, if required.
Proper arrangements will prevent the blade from
jamming as the pipe is cut through.
Fig F
Attaching the pipe saw to the pipe
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. F/1).
Position the pipe saw on top of the pipe so
that the edge of the lower blade guard is at
the cutting mark. Fasten the pipe saw to the
pipe by turning the gripper adjustment handle
until the gripper grips firmly the pipe to be cut
(Fig F/2). Lock the mechanism by turning the
gripper safety (Fig F/3). Hold the pipe in place
and ensure that pipe saw moves freely in the
direction the pipe is fed. For sake of safety
ensure the pipe saw leads are to the left of the
pipe saw. The pipe saw is now ready for cutting.
Piercing the pipe wall
Fig G
Grip the gripper firmly with your right hand
and place your left foot on top of the pipe
approximately 50cm from the pipe saw. Turn
the saw until it leans slightly forward (Figure I).
When starting the motor, first of all release the
power-switch locking lever (Fig G/1) and push
the power switch all the way down (Fig G/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 I /1).. Look at the UNLOCK button
during the piercing operation. When UNLOCK
button is locked, i.e. the yellow mark disappears
(Fig H), pipe saw is locked in the sawing
position, and you can safely start sawing around
the pipe.
Fig H
Sawing around the pipe
Start sawing by feeding the pipe saw forward
and fix the pipe with your left foot (Fig I /2). 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
(Fig J). Start a new feeding movement, and
feed continuously forward ca. 1/6 of the
pipe’s circumference. Repeat until the pipe is cut
off (Fig K).
Fig I
Select the sawing / feeding speed as per the
material and the thickness of the wall. Too high
speed can damage the blade, overload the pipe
saw and give a poor sawing result.
Fig J
When the pipe is cut off, push the UNLOCK
button forward until the yellow mark is visible
and the locking is released (Fig L/1). Now raise
the motor unit to starting position (Fig L/2).
Release the power switch (Fig L/3). When the
blade has stopped, open the gripper safety
mechanism (Fig L/4) and disengage the pipe
saw from the pipe by loosening the gripper
adjustment handle. (Fig L/5). Ensure that the
moving lower blade-guard is lowered into safety
Should there be problems during piercing or
sawing, abnormal sounds or vibrations due to
which you have to interrupt sawing before the
pipe is cut through, release the blade by pushing
the UNLOCK button forward until the UNLOCK
button is released, and lift the motor unit up.
Once the problem is cleared, start sawing again.
Fig K
Never start the motor, when the motor unit is
locked in sawing position or teeth of the blade
contact the pipe to be sawn.
Overload protector and rotation speed
The saw has a two-speed rotation speed control
(Fig A/16). When sawing stainless or acid-proof
steel use the lower rotation speed l. When
sawing other materials use the faster rotation
speed ll. The saw also has an overload protector
which switches the power off automatically in
an overload situation. The motor part has a red
indicator light (Fig A/5), which flashes alerting
you to the overload and is lit continually when
the overload protector has been triggered. If the
light begins to flash, the motor must be cooled
down. Stop sawing and allow the motor to cool
down. You can speed up the cooling process by
running the motor without loading it. When the
motor has cooled down sufficiently, the light will
stop flashing or turns off and you can continue
Fig L
Straightness of cut and adjusting wheel
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 (Fig A/8) which be used for
improving the quality of the cut and for reducing
the misalignment.
Fig M
The adjustment applies only to the actual pipe
size and material, and the wheel may have to be
readjusted as the blade is worn.
Step to left
Step to right
Fig N
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.
Installing and changing
the saw blade
WARNING: To reduce the risk of injury,
turn unit off and disconnect it from
power source before installing and
removing accessories, before adjusting or
when making repairs. An accidental start-up
can cause injury.
Fig O
Remove the power plug from the socket.
Check that the motor unit is locked in the upper
Remove the blade guard cover (Fig. O/1) by
opening the screw (Fig. O/2). Press the spindlelock button (Fig. A/13) and simultaneously rotate
the blade by hand until the spindle-lock button
drops a further distance of about 7 mm. 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).
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 finger bolts.

Maintenance and
servicing instructions
Remove the power plug from the socket
before servicing or cleaning the pipe saw. All
maintenance operations carried out on the pipe
saw’s electrical components must be carried out
at an approved service agency.
Maintenance, Environment, Guarantee
Check the condition of the blade. Replace
a bent, blunt, or otherwise damaged blade with
a new one. Using a blunt blade can overload the
pipe saw’s electric motor. When you notice that
the blade is blunt, do not continue sawing with
it, as the blade may become so badly damaged
that it will not be worth sharpening. A blade in
sufficiently good condition can be sharpened
a few times by a professional sharpening

and its joints (Fig. P/2). Also clean and lubricate
the gripper’s trapezoidal screw (Fig. P/3) and
the two worm screws on it (Fig. P/4).
Blade guard
When you have sawn plastic pipes and then
intend to start sawing metal pipes always clean
the inside of the blade guards. Hot particles
derived from sawing metal will burn plastic
particles, which may release toxic smoke. Make
it a rule to clean the blade guard regularly, and
pay special attention to keep the moving blade
guard movement from becoming hampered.
Lubricate the axis of the moving blade guard

Tips for using Exact
PipeCut saws
Factors that affect the lifetime of the saw
Diamond blade should only be used for cutting
cast iron pipe. It is not recommended to cut cast
iron with TCT or Cermet blades.
Clean the inside of the blade guards after cutting
plastic pipe.
Smaller pipe is easily cut by rotating the pipe
by hand either on a table or on the floor. Please
note: rotate pipe towards you when rotating by
hand and be careful not to rotate too fast.
Check the condition of the blade regularly.

The cutting procedure is divided into two stages;
first saw through the pipe wall, then complete
the cut by sawing around it.
Do not overload the saw by cutting continuously.
The saw will be overheated and the metal parts
can become burning hot. This will also damage
the motor and the blade. The rule is 2.5 minutes
in use and 7.5 minutes rest.
Keep the feeding speed constant. This will
extend the lifetime of the blade. For example
cutting time for a steel pipe diameter of 6’’
(170mm), and a wall thickness of 1/5’’ (5mm), is
15-20 seconds, and for a cast-iron pipe diameter
of 4’’ (110mm), with a wall thickness of 1/6’’
(4mm) is 20 to 25 seconds.
