Maintenance Instructions
To ensure safe and proper operation of Manitowoc cranes,
they must be maintained according to these maintenance
instructions and the Operator Manual provided with the
crane.
Crane maintenance and repair must be performed by
personnel who by reason of training and experience are
thoroughly familiar with the crane’s operation and required
maintenance. These personnel shall read the Operator
Manual and Service/Maintenance Manual before attempting
any maintenance procedure. If there is any question
regarding maintenance procedures or specifications, contact
your Manitowoc Cranes dealer for assistance.
NOTE: Training/qualification of maintenance personnel is
responsibility of crane’s owner.
Safe Maintenance Practices
Perform the following procedure (as applicable) before
starting a maintenance procedure.
1. Park the crane where it will not interfere with other
equipment or operations.
2. Lower all loads to the ground or otherwise secure them
against movement.
3. Lower the boom onto blocking at ground level, if
possible, or otherwise secure the boom against
dropping.
4. Move all controls to the OFF position and secure all
functions against movement by applying or engaging all
brakes, pawls, or other locking devices.
5. Stop the engine and render starting means inoperative.
6. Place a warning sign at the start controls, alerting other
personnel that the crane is being serviced and the
engine must not be started. Do not remove the sign until
it is safe to return the crane to service.
When performing maintenance or repair procedures on the
crane, follow these guidelines to prevent personal injury or
machine damage:
• Wear clothing that is relatively tight and belted.
• Wear appropriate eye protection and an approved
hard hat.
• Never climb onto or off a moving crane. Climb onto
and off the crane only when it is parked and only
with the operator’s permission.
• Use both hands and handrails, steps, and ladders
provided to climb onto and off the crane.
• Lift tools and other equipment (which cannot be
carried in pockets or tool belts) onto and off the
crane with hand lines or hoists.
• The boom and gantry are not intended to be used as
ladders. Do not attempt to climb the lattice work of
the boom or gantry to get to the maintenance points.
If the boom or gantry is not equipped with an
approved ladder, lower them before performing
maintenance or repair procedures.
• Do not remove the cylinders until the working unit
has been securely restrained against movement.
• Pinch points are impossible to eliminate. Watch for
them closely.
WARNING
Burn and Inhalation Hazards!
Temperature of exhaust and exhaust components for Tier
4F engines can be higher than other engines.
To prevent death or serious injury:
• Avoid physical contact with exhaust gases and
exhaust system components.
• Keep all flammable materials away from the exhaust
system to prevent fire.
• If it is necessary to service the crane while the engine
is running, turn OFF the diesel particulate filter (DPF)
regeneration using the switch in the cab to prevent
higher exhaust temperatures.
WARNING
Prevent Personal Injury!
Do not attempt to maintain or repair any part of the crane
while the engine is operating, unless absolutely
necessary. Wait for the engine and machinery to cool
before servicing them.
If the engine is operating, follow these guidelines to
prevent injury:
• Keep clothing and all body parts away from moving
parts.
• Use extreme caution when working around
machinery. It can be extremely hot.
• Maintain constant verbal communication between the
person at the controls and the person performing the
maintenance or repair procedure.
