3.2.2 Safety instructions for transport trolley
WARNING!
Risk of falling items causing serious personal injury if not used correct and with
caution.
•If the transport trolley is to be lifted the blade guard must be correctly fitted
and secured over the saw blade. Never lift the transport trolley with only the
saw blade fitted! If the trolley tilts over during lifting, the saw blade can fall out
of the trolley can cause fatal injury.
•The total weight of the trolley including load may not exceed 170 kg to be able
to drive and lift it securely.
•The transport trolley may only be loaded with the machine and accessories as
instructed in 3.2.1. Extra equipment may be stored in the lower tool box. Other
use is not intended.
•Tracks longer than 2.3 m can rend the transport trolley unstable and make it tilt
over, which can damage equipment and property. Never load more than 2 pcs
of 2.3 m track. The track must be long enough to reach the upper hooks.
•The transport trolley should be placed on a stable, flat surface. If placed on a
sloping surface, it may become unstable (slope <5 °). Also consider the stability
if the trolley is loaded unevenly.
•Do not lift or move the transport trolley unless all loaded parts are positioned
correctly in the specified location and securely fastened without risk of
something falling off. Always use the locking functions and safety straps.
•Lifting with a crane may only take place by using the two lifting eyelets at the
same time and the lifting force must then be as vertical as possible. When lifting
at an angle, it must not exceed 45 ° (See picture below). The lifting equipment
must have been tested and approved.
•Never stand below of near the load during lifting.
•The power pack should always be shut off and disconnected from the mains

Mounting of track feet and tracks
3.3.1 Positioning of track feet
1. Use the Pentruder templates to simplify the setup of the wall saw. It will help position the track feet to avoid
re-aligning them when cutting a rectangular opening. The track foot can swivel, so it only needs to be set up
once at each corner, for example when cutting a door opening.
2. Minimum two track feet are required to mount one track. The distance between the track feet may not
exceed 2.0 meters (79”). If blades larger than 1200 mm / 48” are used, set the track feet closer than 2.0
meters / (79”).
3. If tracks with only one gear rack are used, make sure all of them are positioned correctly to engage with the
travel gear on the wall saw.
The distance from the edge of the feet to the cut line is
127 mm (5”). The distance from anchor bolt to the cut
line is 217 +- 25 mm (8.54 +- 1”).
Setup examples
!Important!
The feet must be fixed with M12 (1/2”) screws of 8.8 quality or higher of adequate
length, depending on anchor depth, using a thick washer and anchors of type HKD
M12 (1/2”) or equivalent.

Operator’s manual Pentruder RS2 wall saw and Pentpak 3 HFi power pack – Original instructions Page 16
WARNING! MOUNT ACCORDING TO INSTRUCTIONS
Risk of serious or fatal cut from saw blade. Uncontrolled movements of the saw or
an escaping or falling saw blade may result in injury or death. Risk of injury from
falling parts.
Uncontrolled movements of the saw or an escaping or falling saw blade may result
in injury or death. Risk of injury from falling parts.
•Track feet may only be mounted according to instructions given in this manual.
•Ensure that the surface where the track feet are fastened is stable, free of
obstacles and adequately lit.
•The track feet and the tracks should be mounted in such a way that they
cannot become detached when the machine is working, or at sudden changes
in load on the anchor bolts.
•Track stops must always be securely mounted at each end of the track(s) to
prevent the saw head from being run off the track unintentionally.
•If HKD type anchors or other high-quality expansion anchors cannot be fixed
securely, the track feet must be securely fixed with through bolts and large
washers to achieve the required level of safety.
•Do not use the machine if the track feet cannot be fastened properly.
•Make sure that the fork is not threaded all the way out before the track is
mounted. Leave at least one turn from the fully out or in position of the fork.
3.3.2 Track system parts
a. Track stop
b. Knurled knob
c. T-slot piece
d. Fork
e. Sleeve nut
f. Levelling screws x 3
Note!
The track feet should preferably be mounted in the position shown in the picture
above, with the base plate of the track foot under the track. If the track feet must
be mounted differently due to the circumstances, this will affect the stability of the
track and more track feet should be fitted to spread the load for increased stability.

Operator’s manual Pentruder RS2 wall saw and Pentpak 3 HFi power pack – Original instructions Page 17
3.3.3 Fastening track feet, and mounting the track on to the track feet
1. Drill anchor holes for each track foot. Follow the
manufacturer’s instructions for the anchors that are
used.
2. Clean the holes and insert the anchors. Fix them
according to the manufacturer’s instructions.
3. Place both track feet over the anchor holes and
tighten the bolts loosely.
4. The height of the fork can be adjusted totally 12 mm
by turning the fork Clockwise or Counter Clockwise
to compensate for irregularities on the wall. Adjust
if necessary.
5. When the fork is completely turned in, turn the fork
about 5 turns Counter Clockwise to make sure the
saw arm doesn’t touch the concrete.
6. Align and position the first track foot with the help
of a template, set square, level or measuring tape.
7. Adjust the levelling screws if necessary and tighten the anchor bolt for the first track foot.
8. Slide in the T-slot pieces from both track feet into the T-slot of the track.
If you are using very old tracks with only one gear rack, make sure it is positioned
correctly to engage with the travel gear on the wall saw, see 3.4 Mounting the
saw head on the track.
9. To make sure the knurled knobs are not lost, tighten them securely.
10. Slide the sleeve nut into the fork of the first track foot in any chosen position
longitudinally on the track.
11. Tighten the sleeve nut on the second track foot to 50 Nm. The hex is 19 mm (3/4”).
12. Slide the sleeve nut into the fork of the second track foot in any chosen position longitudinally on the track.
Do not tighten at this point.
13. Adjust the levelling screws on the second track foot so that the track is not warped due to unevenness of
the concrete.
14. Fasten the sleeve nut on the second track foot to 50 Nm. Make sure there is no or a very small gap between
the track foot fork and the track.
15. Track stops should always be fitted at the end of the track.
WARNING!
•Be careful to position the sleeve nut in the bottom of the fork on the track foot.
This countersink at the bottom of the track foot is to prevent the track coming
off the track foot in case the sleeve nut is not tightened properly.
•If tracks with only one gear rack are used, make sure all of them are
positioned correctly to engage with the travel gear on the wall saw.
•Track stops must always be fitted at the end of the track.
!Important!
The distance between the track feet should be no more than 2 meters / 79”. When
bigger blades than 1200 mm / 48” are used, we recommend setting the track feet
closer than 2 meters / 79”.
Note! Be sure to check that the fork is aligned with the track and that there is no gap
which can cause the track to be warped and the blade to cut un-straight.
No gap!

3.3.4 Joining two or more track tracks together
If tracks are to be joined without a joint block the fork of the track foot should be positioned centrally under the
joint. True up the tracks carefully using a spirit level or a straightedge.
When using joint blocks, a track foot must be placed within 60 cm (2 ft) of the joint Block.
WARNING!
•Joint Blocks are for connecting two tracks together and are not designed to
alone handle the full load of the saw when cutting, therefore, one track foot
must be mounted within 60 cm (2 ft) of all Joint Blocks).
•If tracks with only one gear rack are used, make sure all of them are positioned
correctly to engage with the travel gear on the wall saw.
Mounting the saw head on the track
a. Lifting handle x 2
b. Locking pin x 2
c. Upper track rollers
d. Lower track rollers
The saw head runs on the track on four track rollers. The upper track rollers are fitted on eccentric shafts, opened
and locked by moving the handles sideways.
1. To open the lifting handles, lift up the locking pins
using the index fingers, and fold the handles outward
from the saw until they lock the most outward, open
position.
2. Fold the saw head onto the track, the bottom track
rollers engaged first, and second the upper track
rollers.
3. Move saw head slightly along the track to engage the
travel gear with the gear rack.
4. Lift up the locking pins, slightly move the locking pins
and move the lifting handles toward the saw, until
they are engaged in locked position.
WARNING!
Before the saw is operated, always make absolutely sure that the lifting handles
are locked in position to prevent the saw from falling off the track.
Note that if a track with only one gear rack is used, it must be positioned in the
right direction to engage with the travel gear on the wall saw. Failure to fulfil this
requirement may lead to the saw head traveling along the track which potentially
could cause severe bodily injury or death.

Mounting of saw blade
3.5.1 Function principle of quick disconnect coupling for the saw blade
Inner blade flange
a. Internal toothing (on inner blade flange)
b. Radial t-slot
c. Outer collar
Outer blade flange
d. Bolts x 3
Spindle parts on wall saw head
e. Internally toothed drive hub
f. Pull stud
g. Tapered guide cone
The saw blade is clamped between the inner and outer blade flanges. Three bolts clamp the blade between the
flanges. For flush cutting, the blade is attached on a flush cutting flange by means of six (6) countersunk screws, and
self-locking type nuts,on the back side of the flange.
The blade flange, regardless of type, is provided with a radial T-slot to the center of the flange. The flange, with blade
fitted, is mounted on the machine spindle and its pull stud which fits in the T-slot in the flange. By turning a Locking
Screw clockwise, the flange coupling can be locked and unlocked.
The flange is driven by the spindle by means of an internally toothed drive hub which grips into a corresponding
external toothing in the flange. This hub is also provided with a tapered guide cone part which centers the flange on
the spindle and at the same time interlocks the coupling.
3.5.2 Diamond saw blade
Only a diamond blade suited for the power of the machine and the material to be cut, concrete, stone material or
masonry, may be used. Never attempt to use a higher spindle speed than the saw blade is intended for. Always
follow the diamond blade manufacturer’s recommendations.
For best cutting performance, check that the correct rotation direction for the saw blade is used.
WARNING!
Failure to respect these requirements may lead to serious or fatal injury to persons in
the surroundings of the machine.
•Never attempt to use a higher spindle speed than the saw blade is intended for.

Always follow the diamond blade manufacturer’s recommendations.

3.5.3 How to fit a saw blade on a standard blade flange:
Centre bore and thickness
•The saw blade bore should be Ø 60 mm -0 +0.1 mm.
•The thickness of the saw blade core must be within 2.9 - 5.0 mm to ensure safe and proper clamping of the
blade.
See picture below.
Checks and maintenance before use
1. Before use, carefully inspect the saw blade and the saw blade bore. The steel core must be completely free
from cracks, dents, burrs and dirt and corrosion, or any kind of mechanical damage.
2. Make sure the friction surfaces of both flanges are undamaged and clean, free from grease and dirt. This is
extremely important to allow the blade flange to be able to securely transmit the torque of the spindle
without slippage. Slippage will cause irreparable damage to the flanges and the blade.
3. Inspect and grease the threads on the three bolts. Usea high-quality grease, preferably a Molybdenum
Disulfide grease. No parts of the blade flange or bolt may ever start to corrode.
Clamping
4. Fit the blade on the inner flange and clamp it with the outer flange by tightening the three bolts to 60 - 70
Nm. A torque wrench must be used.
WARNING!
Failure to respect these requirements may lead to serious or fatal injury to persons in
the surroundings of the machine.
•The three bolts are manufactured from a very high grade aerospace quality
stainless steel. The threads on the bolts may never be allowed to be dry. They
must always be greased with a high-quality grease, preferably a Molybdenum
Disulfide grease. Tightening dry fasteners may cause loss of bolt tension which
can result in several serious problems: Lack of clamping force on the blade,
which in turn can result in serious injury, and even fatal injury to persons in the
surroundings of the machine, as well as bolt fatigue due to low bolt preload.
•To avoid danger, the saw blade must always be fitted correctly, and a torque
wrench must be used to tighten the bolts to the correct torque. The instructions
given above must always be followed to avoid incorrect and dangerous
mounting of the blade.
The blade and flange are now ready to be fitted on to the machine spindle by using the quick coupling.
