6.1 Preparations before starting
DANGER Fragments flying around
Fragments of material which come loose while operating
the hydraulic attachment may be flung away and can
cause serious injury if people are hit by them. Small ob-
jects falling from a great height can also cause serious
damage.
During hydraulic attachment operation the danger zone
is considerably greater than during the excavation oper-
ation due to fragments of stone and pieces of steel flying
around, and for this reason the danger zone must, de-
pending on the type of material to be worked on, be en-
larged correspondingly, or secured in a suitable manner
through corresponding measures.
u Secure the danger zone.
u Ensure that no persons are within a distance of 15m
(50ft) during cutting work.
u Ensure that no persons are within a distance of 50m
(165ft) during cutting work on reinforced steel.
u Stop the hydraulic attachment immediately if anyone
enters the danger zone.
u Close the windscreen and the side windows of the
driver's cab.
u The cabin of the hydraulic carrier must be protected
by means of suitable measures (e.g. armoured glass,
min. class P4A according to DINEN356) against
damage due to flying rock.
u Make sure no flying fragments can leave the danger
zone (e.g. safety fence).
WARNING Falling carrier
A carrier falling or tipping over due to the surface not be-
ing level may cause serious injury and material damage.
u Always observe great care when moving the carrier.
u Do not use the hydraulic attachment until the carrier
is positioned stably.
NOTICE Damage due to a failure to observe the operat-
ing conditions
A failure to observe the compressive strengths of the
cutting material can lead to severe damage to property.
u Prior to every cutting process check the compressive
strength of the cutting material.
u Never exceed the max. compressive strength of the
cutting material permissible during cutting work (see
chapter Technical specifications).
Depending on the material being cut, round attack picks
will wear at different rates. A particularly high wear rate
should be expected working in the following materials:
• reinforced concrete
• rock with a high SiO
2
content, when using spray wa-
ter and when cutting under water
• hard rock such as granite, basalt
Note: Prior to using the drum cutter in the aforemen-
tioned materials, contact the authorized Customer Cen-
ter / Dealer in your area in order to guarantee optimum
working efficiency. The authorized Customer Center /
Dealer will advise on the use of suitable tools and the
requisite cutting capacity.
n
Before using the drum cutter always carry out all
maintenance actions mandatory before and after op-
erating (see chapter Maintenance schedule).
This is to prolong service life and maintain high and
save productivity.
n
Make sure that there are no people in the danger
zone.
n
Start the carrier as instructed by the carrier manufac-
turer.
n
Raise the drum cutter.
n
Let the carrier heat up until the operating temperature
prescribed by the carrier manufacturer has been
reached.
n
Put the carrier in working position.
6.2 Commissioning
Note: Observe the carrier's safety and operating instruc-
tions for the following essential actions.
n
Check all fastenings, hoses and couplings.
n
Check the hydraulic oil level and shut-off valves.
n
Check all hydraulic connections for leaks and tight-
ness.
NOTICE Damage due to incorrect commissioning
Idle running during the first use of the hydraulic motor
can result in damage to the motor.
u Load the motor when first starting up.
n
Switch motor on.
n
Bring the motor slowly up to the normal operating
conditions (oil volume, oil pressure).
6.2.1 Checks during commissioning
n
Check the following points when first operating the
drum cutter:
