WARNING: NEVER OPERATE ANY AERIAL EQUIPMENT WITHOUT WEARING AN APPROVED
BODY HARNESS. ATTACH THE HARNESS LANYARD TO THE "D" RING ON THE
BOTTOM OF THE UPPER BOOM. DO NOT OVERLOAD BUCKET.
Use the Platform Control Station to elevate, and rotate the bucket as necessary to get to the working position. When the working
position is reached on a gravity leveled bucket, engage the bucket lock.
ELECTROCUTION HAZARD, STAY AT LEAST 10 FEET (3.0 m) FROM POWER LINES.
THIS UNIT IS NOT INSULATED FROM ELECTRIC SHOCK.
DEATH OR SERIOUS INJURY TO OPERATORS AND/OR BYSTANDERS CAN RESULT
To return to the stowed position on a gravity leveled bucket, unlock the bucket lock, and rotate the bucket to a position that
provides a clear line of descent. Using the Platform Control Station, operate the controls as necessary to lower the bucket to the
ground. Exit the bucket. Use the lower controls to fully lower the booms and move them into the stored position in the boom rest.

CRANE OPERATION

After the trailer has been properly parked, and all four outriggers are properly extended and set, the bucket must be removed.
To remove the bucket, use the Lower Control Station and raise the lower boom until the bucket reaches the ground. When the
bucket is resting on the ground, pull the bucket-yoke lock pin(s) and rotate away from the holes. Gravity leveled bucket yoke
collar will slide from the boom. Self leveled bucket yoke arm plates can be lifted from the pivot box. Remove the bucket from
the boom and move it clear of the work area. NOTE: The green light on the Lower Control Station will be "ON" if the unit
is set-up properly. Loads of 300 pounds maximum can be lifted using the lanyard ring on the end of the boom. Do not
exceed the 300 lbs. load rating Loads of 300 pounds maximum can be lifted to approximately 36 feet with a side reach of
approximately 8 feet by using the lanyard ring (See Figure i-2).
Proper sequence of operation to lift objects from ground to desired height is:
1.
Secure the load to the lanyard ring using safe rigging practices.
2.
Using the Lower Control Station, lift the load off the ground, then rotate to desired direction. Use the RAISE controls to raise
the booms, and lift the crane load to the desired position.
3.
Use the boom LOWER controls to set the crane load down.
Reverse the sequence to bring objects down from a height, i.e.:
1.
Use the upper boom RAISE control to lift the load. Rotate the load to a position that allows a clear line of descent.
2.
Lower the load, using the boom LOWER functions.

SHUTDOWN

Make sure that the bucket is properly attached to the upper boom and the bucket-yoke lock pin(s) are securely locked. On a
gravity leveled bucket, swing the bucket up and insert the lock clip. Use the bucket lock and secure the bucket in the stowed
position. Store the booms in the boom rest, and secure the tie-down strap. Lower the third wheel assembly. Retract and lock
outriggers in stored position. Turn the key switch to OFF.
CAUTION: DO NOT RAISE THE OUTRIGGERS OR MOVE THE TRAILER UNLESS THE BOOMS
ARE STORED AND SECURED!
