Hoses
For connection on the machine, the hydraulic hose must be approved for a working pressure of at least 160 bar (2300 psi) and have a
12.7 mm (½ in.) inner diameter. To resist exterior wear and tear, we recommend using a 2-layer hydraulic hose. The machine
connection marked P (pump) is the oil inlet, and the connection marked T (tank) is the oil outlet.
Always connect both hoses and make sure that all hose connections are tight. Never carry the machine by the hose.
Quick-Release Couplings
The original hydraulic hoses are tted with Flat-Face quick-release couplings that are strong and easy to clean. The quick-release
couplings are tted so that the male connection supplies oil and the female connection receives oil.
Wipe all couplings clean before connecting. Ensure that couplings are clean and correctly engaged before operation. Failure to do so
may result in damage to the quick couplings and cause overheating and cause foreign matter to enter the hydraulic system.
Hydraulic Oil
In order to protect the environment, Altrad Belle recommends the use of biologically degradable hydraulic oil. No other uids must be
used.
Viscosity (preferred) 20-40 cSt.
Viscosity (permitted) 15-100 cSt.
Viscosity index Min. 100.
Standard mineral or synthetic oil can be used. Make sure to only use clean oil and lling equipment.
When the machine is used continuously, the oil temperature will stabilise at a level which is called the working temperature. This will,
depending on the type of work and the cooling capacity of the hydraulic system, be between 20-40°C (68-104°F) above the ambient
temperature. At working temperature, the oil viscosity must lie within the preferred limits. The viscosity index indicates the connection
between viscosity and temperature. A high viscosity is therefore preferred, because the oil can then be used within a wider temperature
range. The machine must not be used, if oil viscosity fails to remain within the permitted area, or if the working temperature of the
oil does not fall between 20°C (68°F) and 70°C (158°F).
Cutting Blades
High-quality cutting blades are often most economical. Lower quality blades often have inferior cutting capacity and a shorter service
life, which results in a higher cost in relation to the quantity of material that is cut. The cutting blades must be approved for free hand
cutting machines and rated for minimum 4400 rpm.
Selecting the right Cutting Blade
The Disc Cutter can be used with both diamond blades and with the more traditional abrasive discs. Store and handle the abrasive
product with care in accordance with manufacturer's instructions.
Abrasive Discs
Using abrasive discs, the Disc Cutter can be used for cutting steel, concrete, asphalt or other material depending on the blade type.
Diamond Blades
Diamond blades are ideal for masonry, reinforced concrete and other composite materials. They are not, however, recommended for
cutting steel.
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 Disc Cutter can be used underwater without any modi cation.
CAUTION
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.
Never cool a hot insertion tool in water, it can result in brittleness and early failure.
