Care And Maintenance; Maintenance Table - Hilti DSH 700 Manual Del Usuario

Reasons for the cutting disc stalling:
• The cut is too deep.
• The kerf closes (e.g. when cutting pipes or slabs).
• The cutting disc is off-square in the kerf.
• The cutting disc is unsuitable for the job (the cutting disc becomes clogged).
• The cutting disc is inserted too quickly into an existing kerf.
The hazardous situations that result from stalling differ, depending on the working position.
• Forward pull can occur when a horizontal cut is being made (e.g. in the ground). The saw suddenly
snatches forward, possibly pulling out of your hands.
• Climbing can occur when a vertical cut is being made (e.g. in a wall). The saw suddenly snatches upward,
possibly pulling out of your hands.
• Kickback can occur if the prohibited area of the disc is brought into contact with the workpiece.
To avoid the hazardous situations that result from stalling of the cutting disc:
▶ When cutting a thick workpiece, increase the depth of the kerf in steps. Avoid excessively deep cuts.
▶ Support slabs or large workpieces so that the kerf remains open during and after the cutting operation.
▶ Always bring the cutting disc into contact with the workpiece from above.
◁ Allow the cutting disc to contact the workpiece only at a point below the rotational axis of the disc.
▶ Take great care when guiding the cutting disc into an existing kerf.
▶ Do not tilt the cutting disc in the kerf.
