Safety precautions at site
Wire sawing can be a very dangerous exercise! All possible safety precautions must be taken to avoid accidents from
happening.
WARNING
BEFORE CUTTING
Before cutting is commenced, make sure that;
•There are no power lines, gas or piping which can be damaged by the
machine.
•The statics of the building are not compromised because of the cut
openings.
•Check with the foreman responsible that all necessary precautions
have been performed before commencing work. Await the approval of
the safety precautions and mounting position of the machine from the
foreman before work is commenced.
•Safety and health regulations at the work place must be followed.
•No work should be commenced which cannot be judged to be safe.
Always use common sense and good working practice.
•Always check that the machine and diamond wire
is in faultless
condition and that all functi
ons are in order before work is
commenced.
•Never use a diamond wire for material which it is not intended for.
•Before cutting is commenced all persons involved must know how the
emergency stop buttons are working.
•Follow the instructions in 5.2 Startin the HF-machine, to make sure the
diamond wire will not start at and/or cut at a too high speed.
WEAR SAFETY EQUIPMENT
•All persons working with, or in the proximity of the machine should
wear safety equipment, i.e. protection helmet, protection shoes,
gloves, eye and ear protectors. The noise level during cutting might
lead to permanent hearing disorders if not ear guards are worn.
•Find out what material is cut and wear appropriate dust mask or
respirator protection if necessary.
MOUNT ACCORDING TO THE INSTRUCTIONS
•Before any kind of service or mounting on the machine is commenced,
the machine must always be disconnected from the electric power
supply.
•The base plate may only be mounted according to the instructions
given in this manual.
•Make sure a guard always is properly fitted during the cutting process
as well as deflectors to protect the free wire to and from the cut.
•The power or force applied on the wire in the 3P8 is higher than on any
other commercially available electrically driven compact (non quarry
type) wire saw. Therefore it is important to splice the wire carefully.
LIFTING AND TRANSPORTING
•Always lift the machine ergonomically correct and in a safe way.
•Should the machine need to be lifted with a crane, this should only be
done after permission and instructions have been given by a person
responsible for safety on the site.

Operator’s manual Pentruder®3P8 HF-wire saw and Pentpak - Original instructions 9
WARNING!
RISK AREA
•The operator shall keep a minimum safety margin of 1.5 m to all
working and moving parts during the operation. Should the machine
fall down from the wall or ceiling it could cause severe injuries. There is
always a danger of wire tear and thereby connected
wire lash.
Deflectors may be necessary in addition to the machine guard.
•The operator should have good supervision over the machine from
each control position.
•The risk area must be roped off and the operator must make sure that
no unauthorized persons are within the risk area.
•Clear the working area and make sure no unauthorized persons are
within the risk area, see drawing below, before the machine is allowed
to be started.
•All guards must be fitted on the machine and properly locked while it is
running and the wire must be protected by deflectors over its whole
free length, as well and to the cut object.
•Never stand in line with the cut line.
•Remember always to cover cut openings so that no person falls down
and hurts himself.
•Secure the concrete before starting work to make sure there is no
possibility that concrete blocks may fall down causing injury or damage
to persons or property.
•Concrete blocks which are cut free may not be allowed to fall freely as
this could compromise the safety of the machine and/or diamond tool.
For drawings of the Machine’s Risk area, see next page.
!Important!
•
The power pack is water cooled and must be drained from water when
the ambient temperature is in the proximity of or below 0 degrees
Celsius. See 4.9.3 Connection to water supply.
•The water supply may only be connected to the short hose on the water
ON/OFF-valve on the power pack. The quick disconnect couplings may
not be replac
ed with couplings that are not fully open when
disconnected.
•The transistor power modules in the power pack are water cooled and
the water pressure must therefore be limited to max 5 bar.
•The power pack should preferably only be operated when it is put on its
back with the warning triangle upwards.
•Connect the HF-power pack only to Pentruder HF-wall saws, Pentruder
HF-Wire Saws, HF-drill motors or any Pentruder equipment which has
been manufactured or approved by Tractive AB.

4Preparations and mounting
Advice about the positioning of the Pentruder 3P8 wire saw
•When setting up the base plate, pay attention to the positioning of the wire going out from and back to the
machine. Try to plan the set-up so that satellite wheels are not needed.
•The 3P8 can most often be mounted directly on the cut object. If this is possible, it is called a direct cut.
A direct cut is preferable as extra satellite pulleys steal power.
•Naturally, in some instances satellite wheels must be used. If this is the case, try to avoid using satellite on
the slack side. This is where the wire goes out from the machine and where the RH swivel wheel is. The RH
side if you stand in front of the main drive pulley.
•Try to position the base plate so that the wire goes back in to the concrete or the cut object with the wire
running over the RH swivel wheel when cutting starts.
•What we are after with these recommendations is to create as little friction as possible on the slack side.
Then the cutting will go faster and the feed regulation will work best.
•Normally, corners will NOT have to be broken off or chamfered before commencing a cut. Maximum torque
is available from 0 motor speed, and the wire can be started smoothly. Note, a new wire with sharp bead
edges is much harder to start over sharp corners than only an ever so slightly used wire. With a new wire, it
may be necessary to chamfer edges on the object to be cut.
Mounting the base plate
The surface where the base plate is fastened should be stable, free of obstacles and adequately lit. The base plate should
be mounted in such a way that it cannot become detached when the machine is working, or at sudden changes in load
on the anchor bolts.
For safety reasons it is very important that the base plate is properly fastened. If mounted on brick or porous concrete
the base plate must be bolted down with M16 / 5/8” through bolts. Use only high quality anchors and bolts.
WARNING!
•If the base plate is not securely fastened to a solid foundation, the very high
forces applied on the wire by the tractive power will cause instability and will
lead to unforeseen events that can lead to serious or fatal injury.
•
If HKD anchors or other high quality expansion anchors cannot be fixed
securely, the base plate must be securely fixed with through bolts and large
washers to achieve the required level of safety.
•Do not use the machine if the base plate cannot be fastened properly.

c. Adjust the height of the carriage by turning the feed
shaft socket with a ratchet or knuckle bar.
d. Tighten the friction clutch socket.
Note! Tighten moderately to 20-25 Nm / 15-18 ft-lbs.
Do not over tighten.
The friction brake should be only moderately tightened so it will
allow the carriage to slide upwards in the event of an abrupt
jamming of the wire. The normal pulling force in the wire is about
100 kg’s for a 22 kW HF-motor. Due to the amplifying effect of the
forces, through the 3 loops in the magazine, the force applied on
the carriages is 6 fold and can be in excess of 1000 kg during an
abrupt jamming of the wire.
4. Mount the upper carriage on the column
a. Loosen the socket on the friction clutch one turn.
e. Slide the carriage over the column, with the feed unit pointing
downward.
b. Adjust the height of the carriage by turning the feed shaft
socket with a ratchet or knuckle bar.
c. Tighten the friction clutch socket.
Note! Tighten firmly, but do not over tighten!

6. Mount a Pivoting head - PD1 (accessory)
Pivoting head-PD1 with column.
In many cases a universal pivoting head can be used to simplify set-up and to add versatility to the system. The Pivoting
Head can for example be fitted on a vertical column and a horizontal column fitted to the Pivoting Head conical quick
coupling.
To use the pivoting head
a. Mount the pivoting head on the column
b. Adjust height and tighten the clamp screws slightly.
c. Use a ratchet or knuckle bar to move the pivoting head to the desired position on the column.
d. Lock the pivoting head with the clamp screws.
e. To mount the second column on the pivoting head, align bolt hole with pull stud hole in the male conical
coupling, insert an eccentric bolt and tighten hard, clockwise, with a ½” knuckle bar or ratchet.
f. Now you can mount the carriages on the horizontal column, see mounting of carriage.
!Important!
•
Be observant so that the eccentric bolt doesn’t slip out of the column when the
column is mounted on the conical coupling on the pivoting head. It MUST be
completely flush with the column side face.
•Before tightening the adjustable male-coupling please make sure the face
teeth are correctly in mesh.
•When the eccentric bolt is removed, do NOT put your fingers in the bolt hole.
•When the pivoting head is mounted, be sure that the locking screws are
tightened to give enough friction between column and pivoting head, to keep
the pivoting head from sliding down the column in an uncontrolled way.
