Action
Put two pallets on the floor, in front of the
position of the mechanical stop.
Note
Using the method to replace the gearbox
with cable harness and DressPack fitted,
is only a recommendation. If it is not pos-
sible to put the arm system close enough
to the robot and keep the cable harness
partly fitted, it is necessary to remove the
cable harness and DressPack in base and
frame first.
CAUTION
The lower and upper arms together weigh
650 kg.
All lifting accessories used must be sized
accordingly!
Remove the remaining screw and lift away
the lower and upper arm together.
Let the cabling run in the lower arm. Make
sure not to stretch any cabling!
Note
Two persons required. One person to oper-
ate the overhead crane and one person to
handle the arm system.
Use a piece of wood or similar as a support
under the arm house when the arm system
is put down on the pallets.
This is done in order not to damage any
parts of the cable harness and DressPack.
Action
DANGER
Make sure that all supplies for electrical
power, hydraulic pressure, and air pressure
are turned off.
