Chapter 3: Robot Installation
Mounting Procedure
1.
Using the dimensions shown in the previous figure, drill and tap the mounting surface
for four M12 - 1.75 x 36 mm (or 7/16 - 14 UNC x 1.50 in.) machine bolts (mounting hard-
ware is user-supplied).
2.
If you are using dowel pins for locating the robot, insert those in the mounting surface.
3.
While the robot is still bolted to the transportation pallet, connect a hydraulic lift to the
eyebolt at the top of the inner link. See Figure 3-1.
WARNING: PERSONALINJURYORPROPERTYDAMAGERISK
Do not attempt to lift the robot at any points other than the eyebolt
provided. Do not attempt to extend the inner or outer links of the robot
until the robot has been secured in position. Failure to comply could res-
ult in the robot falling and causing either personnel injury or equipment
damage.
4.
Remove the four bolts securing the robot base to the pallet.
Retain these bolts for possible later relocation of the equipment.
5.
Lift the robot and position it directly over the mounting surface.
6.
Slowly lower the robot while aligning the base and the tapped holes in the mounting
surface.
NOTE: The base casting of the robot is aluminum and can easily be dented if
bumped against a harder surface.
7.
Verify that the robot is mounted squarely (cannot rock back and forth) before tightening
the mounting bolts.
8.
Install the user-supplied mounting bolts and washers. Tighten bolts to the torque spe-
cified in the following table.
WARNING: PERSONALINJURYORPROPERTYDAMAGERISK
The center of mass of the robot may cause the robot to fall over if the
robot is not secured with the mounting bolts.
NOTE: Check the tightness of the mounting bolts one week after initial install-
ation, and then recheck every 6 months. See Maintenance on page 99 for periodic
maintenance.
