Action
Orient the small dowel pins in gearbox and
frame, and at the same time, match cross
roller bearing dowel pin to the hole in the
base, while lowering the complete arm
system carefully onto the long guide pins.
Note
It is possible to rotate the cross roller
bearing and the gearbox by hand, to match
the small dowel pins.
Slowly lower the complete arm system,
while checking the position of the small
dowel pins and the guide pins.
Action
Attach the screws that hold the cross roller
bearing to the frame. Do not tighten yet.
Tip
This procedure is best done with two per-
sons working together:
• Person one: working under the base,
holding the torque wrench in place,
making sure the bit is correctly fitted.
• Person two: working beside the ro-
bot, working with the torque wrench.
