Mounting the DS-TS30-54 and DS-TS30-45 saw head, hydraulic hoses and saw blade
– The saw arm
should be in the starting position (vertically
upwards). Press the release buttons
with the thumbs and pivot the
grips
through approx. 180° outwards towards the saw arm. The
cam-action rollers
on the saw arm side are now in the open posi-
tion.
– Position the saw head on the rail (rail already fastened securely),
engage the carriage with the teeth on the rack and close the cam-
action rollers by pressing the lockbuttons with the thumbs and pivot-
ing the grips into the closed position.
– Connect the D-PH 34 hydraulic hose
(

″
pressure hose for the
motor) and the D-FH 4/14 hose set
(
1
/
4
″
control hose) to the saw
head.
– Bring the blade guard holder
into a suitable position on the saw
arm. Use the hex. wrench (10 mm AF), item no. 221193/6, to tighten
the hex. screw in the centre of the saw arm securely before mount-
ing the saw blade. The holder and the blade guard then remain in the
desired position during the entire sawing procedure.
– Carrying grip
Mounting the saw blade
– Select the saw blade (diameter, Type BC or LC) depending on the concrete, the job to be done and the cutting
sequence using saw blades of different diameters.
– Select the correct gear (slow speed - 1
st
gear / fast speed - 2
nd
gear).
– Position the saw blade, observing the correct direction of rotation, on the drive hub of the saw arm.
– Fit the special blade flange
and the special screw
M12
×
25 (10.9 grade), item no. 221343/7.
– Rotate the blade slightly so that the countersunk holes for fastening the blade for flush cutting are positioned
BESIDE the 6 water grooves.
– Use the 19 mm AF ring wrench to tighten the special M12 screw securely.

Instructions for handling hydraulic hoses and hydraulic couplings
– Always clean the couplings with a cloth before connecting. Turn the securing ring on the coupling after the
click is heard.
– To ensure reliable operation and extend the life of the entire system, it is important that all hydraulic couplings
are cleaned daily.
– Do not leave hydraulic couplings lying in the dirt and do not knock them against concrete surfaces. Avoid drag-
ging hydraulic hoses over sharp edges.
– After transporting all modules to the workplace, the hydraulic unit should be positioned correctly and the
hydraulic hoses connected to the unit immediately. In this way, no pressure can build up in the hoses even
when directly exposed to the heat of the sun.
– If the hydraulic hoses cannot be connected, try to relieve pressure in the system by operating all valves (con-
trols). Alternatively, the D-PRT pressure release valve can be used to release the pressure. The small quanti-
ty of oil which escapes should be caught in a cloth.
– Before disconnecting couplings, first turn the locking sleeve until it engages in the “open” position.
