counterweight is not recommended.
Refer to (Figure 5-5) for counterweight removal.
1. Fully extend and set the outriggers.
NOTE: Turntable lock pin can only be engaged with boom
over front.
2. Rotate the superstructure so the counterweight is over
the front of the carrier to gain additional clearance.
NOTE: The counterweight weighs approximately 4300 kg
(9480 lb).
3. Lower and fully retract the boom
4. Shut down crane.
5. Attach an adequate lifting device to the counterweight.
6. Ensure the four counterweight leveling capscrews are
set for maximum clearance with the turntable.
7. Slowly raise counterweight until pin assembly can be
removed by pushing and turning the pin.
8. Remove pin assembly from opposite side.
9. Lower counterweight until attaching lugs are clear of the
turntable.
10. Back counterweight away from turntable until it is clear
of crane.
11. Replace pin assembly in turntable counterweight
mounting lugs.
12. Move counterweight far enough from crane to allow the
turntable/superstructure to clear during repositioning.

Fixed Counterweight Installation
1. Fully extend and set the outriggers.
2. Rotate the superstructure so the counterweight will be
over the front of the carrier to gain additional clearance.
3. Shut down crane.
NOTE: The counterweight weighs approximately 4300 kg
(9480 lb).
NOTE: Use of a forklift to remove/install the fixed
counterweight is not recommended.
4. Attach an adequate lifting device to the counterweight
and lift the counterweight into place on the
superstructure, aligning the mounting holes on the
counterweight to the holes in the superstructure.
5. Install the counterweight mounting pins and secure them
in place with hitch pin retainers.
6. Remove the lifting device from the counterweight.
7. Using the four counterweight leveling bolts, level the
counterweight and eliminate any relative movement
between the counterweight and turntable. Maximum
width of counterweight shall not exceed 6.0 mm (0.25 in)
out of level with the turntable bearing when measured
from either counterweight outer edge.
DANGER
Death or serious injury could result from being crushed by
a falling counterweight.
Ensure the retainer pin is properly installed to secure the
counterweight mounting pin.
CAUTION
When lifting/handling the counterweight, keep the chains/
straps vertical to minimize side pull on the lifting lugs.
