Ring saw HRH500
Preparatory operations
The work is prepared in the following manner:
1.
Clarify the fundamental conditions:
–
Position of pipes and cables in walls, floors and ceilings
–
Cooling water drainage (danger of electric shock and water damage)
2.
Securing the site.
3.
Secure out-cuts from wall, ceilings or floors (e.g. crane or supports). Consider the weight of
concrete (1m
3
weighs 2400 to 2700kg). Decide on the position and sequence of cuts.
4.
Visually inspect the ring saw.
Position and sequence of cuts
Decide on position
X
Obtain information on sawing concrete or sawing brickwork:
–
Where does the reinforcement run?
–
Is the concrete heavily or lightly reinforced?
X
Cuts in concrete to be as near as possible at right angles
Define the sequence of cuts
An incorrect sequence of cuts can lead to the cutting ring jamming.
X
Define the sequence of cuts (e.g., for a window cut-out carry out the bottom cut first, then
the side cuts and finally the top cut).
