Push-pull speed of power head is controlled by one switch. Push-pull
speed of power head will be doubled by pressing high-speed push-pull
switch of power head and normal speed will be restored by loosening the
switch. High-speed push-pull can be adopted to save auxiliary period
during drilling or back towing if main axle is not connected to auger stem.
(Mud pump will stop operation automatically when using high-speed
push-pull function.)
High-speed rotation of power head shall be controlled by manual valve on
power head box. Manipulation rods of the valve shall be placed in different
positions to guarantee different rotation speed of power head. (Please do
not use high-speed rotation function of power head during large-aperture
construction.)
2.9 Principle of hydraulic system is shown in Figure 2.
