Ring saw HRG500
Preparatory operations
The work is prepared in the following way:
1.
Sort out fundamental conditions:
–
Location of supply lines in walls, floors and ceilings.
–
Cooling water drainage (risk of electric shock and water damage)
2.
Securing the site.
3.
Secure cut-outs in walls, ceilings and floors (e.g. crane or supports). Take weight of concrete
into consideration (1 m
3
corresponds to 2400 to 2700 kg). Decide on position and sequence
of cuts.
4.
Perform a visual inspection of the ring saw.
Position and order of cuts
Define position
X
Obtain information about the concrete or masonry that is being sawn.
–
Where does the reinforcement run?
–
Is it heavily or lightly reinforced?
X
Cut across the concrete if possible.
Define the sequence of cuts
Using the wrong cut sequence can result in the disk grinding ring getting jammed.
X
Define cutting sequence (for example, for a window cutout carry out the bottom cut first,
then the side cuts and finally the top cut).
