Safety and operating instructions
There is a wide selection of blades with diamond
segments for various kinds of material. The local
environment (type of stone in the concrete or asphalt)
will often determine which type of diamond blade is
the ideal and most economic solution. Diamond
blades are generally available as dry cutting or wet
cutting blades. If dry cutting blades are used, a dust
collector can be connected to the blade guard for
operation in areas where no water can be accepted.
It is, however, most common to use a wet cutting
diamond blade and a small amount of water to
remove the dust and cool the diamond segments.
With a diamond cutting blade, the cut-off saw can be
used underwater without any modification.
NOTICE Never cool a hot insertion tool in water, it
can result in brittleness and early failure.
Fitting and removing the cutting blade
1. Untighten and remove the nut.
2. Remove the washer.
3. Remove and change the cutting blade.
4. Attach the new cutting blade. Be aware of the
direction of rotation. If there is an arrow on the
blade, this must point in the same direction as
the red arrow on the blade guard.
5. Attach the washer above the cutting blade and
tighten the nut.
6. Make sure that the blades/discs are mounted
correctly and tightened before use.
7. Start the machine at low speed for one minute
in a safe position and check the direction of
rotation of the cutting blade. Stop the machine
immediately if it starts to vibrate strongly or if you
see other defects.

Operation
WARNING Involuntary start
Involuntary start of the machine may cause injury.
Keep your hands away from the start and stop
►
device until you are ready to start the machine.
►
Learn how the machine is switched off in the event
of an emergency.
►
Stop the machine immediately in all cases of
power supply interruption.
NOTICE Never exceed the maximum flow stated
on the machine, as this might lead to failure of the
cutting blade and damage to the machine.
Preparation before starting
The following checks should be made each time you
start to use the cut-off saw. All these checks concern
the serviceability of the cut-off saw. Some concern
your safety:
♦
Clean all safety stickers. Replace any that are
missing or cannot be read.
♦
Inspect the hoses generally for signs of damage.
♦
Inspect the blade for wear and damage. Do not
use an excessively worn or damaged blade.
♦
Connect the machine.
Ensure that the hydraulic couplings are clean and
♦
fully serviceable.
Never invert the cut-off saw without first isolating
♦
it from the power source. The blade might be
ejected forcefully while connecting it, if the saw is
connected to the power source.
♦
Ensure that any power source you plan to use is
compatible with the cut-off saw that is used, see
"Technical data". Use recommended LFD oil flow
divider, if the flow from the power source can
exceed the maximum allowed oil flow.
♦
Never exceed the maximum relief valve setting
stated on the machine.
♦
Always connect P and T hoses before starting.
