Operation procedures (Breaking)
2 – 14
When the machine hammers a rock while the front of the base machine is lifted, the vibration
during hammering will be transmitted also to the crawler, so avoid such operation for protection
of the crawler. Exercise care so that thrust will be applied at all times during hammering
operation. Avoid idle hammering.
Direction of thrust
The direction of thrust should coincide with the direction of the rod shaft. Hammer the rod
against rock as perpendicularly as possible. When it hammers a rock slantwise, the rod and
front bush will be galled or the rod will be broken. Select the parking ground carefully for stable
hammering, and hammer the rod in a firm and stable manner.
