Jig to get close. The Star Adventurer looks like a cool bit of gear I brought the eq head separately to work with little portable mount I own.
Are you trying to polar align with the polar scope or drift aligning ? Checking the manual the polar scope looks like it has to be calibrated to the RA axis and then adjust alt/az {not much free play with the azimuth on the eq head}controls to get the pattern provided with the polar scope to match the asterism sigma octanis is in . Can be tricky if your not familiar with finding the SCP. I'd plan spending a few hours getting the mount drift aligned and marking the surface where your tripod stands and checking the view through the polar scope to get accustomed to that area of sky {can also check your compass etc}.
