2250 OPERATOR MANUAL SAFETY INFORMATION
rigging pendants or straps), securely block each section
to provide adequate support and alignment.
• Unless authorized in writing by Manitowoc Cranes, do
not alter the crane in any way that affects the crane’s
performance (including welding, cutting, or burning
structural members or changing pressures and flows of
air and hydraulic components). Doing so will invalidate
all warranties and capacity charts and make the crane
owner/user liable for any resultant accidents.
• Keep the crane clean. Accumulations of dirt, grease, oil,
rags, paper, and other waste will not only interfere with
safe operation and maintenance but also create a fire
hazard.
• Store tools, oil cans, spare parts, and other necessary
equipment in tool boxes. Do not allow these items to lie
around loose in the operator’s cab or on walkways and
stairs.
• Do not store flammable materials on the crane.
• Do not return the crane to service at completion of
maintenance or repair procedures until all guards and
covers have been reinstalled, trapped air has been bled
from hydraulic systems, safety devices have been
reactivated, and all maintenance equipment has been
removed.
• Perform a function check to ensure proper operation at
the completion of maintenance or repair.

can threaten the environment.

substances.
Handle and dispose of waste according to local, state, and
federal environmental regulations.
When filling and draining crane components, do not pour
waste fluids onto the ground, down any drain, or into any
source of water.

• Always fill or add fluids with a funnel or a filling pump.
• Immediately wipe up any spills.
