INSTRUCTIONS FOR USE
Operating instructions
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.
Ensure the pipe is empty.
It plastic pipes have been cut with the pipe saw (resulting
in long, statically charger slivers), open the blade guard
cover, and clean carefully the lower blade guard and the
entire pipe saw.
Connection to the mains power supply
Ensure that the mains voltage is the same as indicated
on the rating plate (Figure 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 (b) on the pipe to
be cut, deduct 20 mm from the required dimension
(Easy-to-remember rule: The cutting mark (a) location
requires a measurement of - 20 mm.) (Figure C).
Setting the pipe on supports
Use the system supports when cutting pipes. This will
ensure safe working and optimum result. Work on flat
underground. 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 (25cm 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.
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. E/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
(Figure E/2). 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
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 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.
Sawing around the pipe
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 (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).
Select the 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.
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 is stationary, remove the pipe saw from
the pipe by loosening the gripped handle (Fig L/4).
Ensure that the moving lower blade-guard is lowered
into safety position.
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.
Never start the motor, when the motor unit is locked in
sawing position or teeth of the blade contact the pipe
to be sawn.

INSTRUCTIONS FOR USE
Overload protection and spin-speed regulator
Model 170 is equipped with overload protection. When
the blade is dull or the cutting speed is too high, the
overload protection cuts power automatically. Restore
the power by pushing the overload protection switch.
There is a spin-speed regulator in model 170E. A suitable
spin speed is selected, determined by the material to
be sawed. There is also an overload protection in the
regulator. It automatically cuts the power off in an
overload situation. The power is automatically restored
as soon as the motor has cooled sufficiently. There is a
red indicator light in the regulator, which warns of an
impending overload and overload protection function.
The indicator light in question turns on for a moment
every time the motor is started. This is normal and does
not require any actions.
Straightness of cut and control 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/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.
Installing and changing the saw blade
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 finger screws (Fig. O/2). Press the spindle-lock
button (Fig. A/11) 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).
14 15 ENGLISH
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.
Blade
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 company.
Gripper unit
Clean the gripper unit regularly with compressed air.
Lubricate the gripper's wheel axles (Fig. P/1) 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 regularly.
Motor
Keep the motors cooling vents clean.
Plastic parts
Clean the plastic parts with a soft rag. Only use
mild detergents. Do not use solvents or other strong
