3.6 SPT HAMMER OPERATION
To operate the SPT hammer, set the mode switch to drilling (Control J,
Figure 3.3). Ensure that the SPT hammer hoses are connected to the top two
outputs on the rig PTO (see 3.5.1). The PTO lever on the main console
(Control H, Figure 3.2) controls the SPT Auto Hammer motor. The height of
the SPT Hammer can be adjusted using the tooling winch control (Control M,
Figure 3.3).
3.7 CABLE PERCUSSION OPERATION
To operate in Cable Percussion mode, set the mode switch to drilling
(Control J, Figure 3.3). With the brake off (Control A, Figure 3.3), the Clutch
Control on the main console (Control B, Figure 3.3) is used to control the
percussive action; pull to lift and push to drop. Cable speed can be adjusted
using the hoisting reel speed control (Control C, Figure 3.3).
