THE REASONS FOR THE SLOW ROTATIONAL SPEED DURING THE PILE

Manual rock drill has slow speed

Manual rock drill has slow speed

Turn the throttle lever gradually and drill at a slow speed until the hole is collared. The drill should be kept at right angles to the work until the hole is collared, then repositioned for angle drilling. Always apply sufficient down pressure to keep the tool from bouncing. [pdf]
