2. Loosen the clamp collars that
secure the counterweight arm
(see Figure 3-28).
3. Adjust the counterweight arm
until the machine hangs level
within five degrees.
4. Tighten the counterweight arm
screws to approximately
30 ft-lbs (40 Nm).
WARNING
Check that all mounting hardware is secure. A loose counterweight can fall
off during operation, seriously injuring the operator or bystanders.
If you need to remove the counter-
weight arm (to simplify rigging, for
example), first do the following to
remove the counterweight from the
counterweight arm:
1. Attach the rigging to the lifting
eye on the counterweight.
2. Loosen the locking screw adja-
cent to the lifting hole (see Fig-
ure 3-29).
3. Loosen the counterweight
adjustment clamp screws (see Figure 3-28).
4. Use a 10-mm hex wrench inserted in the hole near the engraving at the end of
the arm to rotate the counterweight arm out of the counterweight.
5. Slide the arm out of the main body.
6. Reinstall the counterweight by reversing this procedure.
A collar on the counterweight arm prevents the counterweight assembly from sliding
free from the main housing assembly if the arm is not clamped securely (see Figure 3-
28). This collar has a urethane face that must face towards the main body clamps. An
o-ring between the collar and the shoulder at the end of the arm allows the collar to
absorb the energy from a sliding impact. If you notice that the collar has been
displaced or the o-ring is missing, correct this before you continue using the machine.
WARNING
Do not remove the stop collar on the counterweight arm. Serious injury or
death can result if the arm is accidentally left unclamped and it slides out of
the main body socket.
