2250 SERVICE/MAINTENANCE MANUAL INTRODUCTION
1
• Relieve pressures before disconnecting air, coolant,
and hydraulic lines and fittings.
• Do not remove the radiator cap while the coolant is
hot or under pressure. Stop the engine, wait until the
pressure drops and the coolant cools, then slowly
remove the cap.
• Read the safety information in the battery
manufacturer’s instructions before attempting to
charge a battery.
• Avoid battery acid contact with skin and eyes. If
contact occurs, flush the area with water and
immediately consult a doctor.
• Stop the engine before refueling the crane.
• Do not smoke or allow open flames in refueling
area.
• Use a safety-type can with an automatic closing cap
and flame arrestor for refueling.
• Hydraulic oil can also be flammable. Do not smoke
or allow open flames in the area when filling the
hydraulic tanks.
• Never handle wire rope with bare hands. Always
wear heavy-duty gloves to prevent being cut by
broken wires.
• Use extreme care when handling coiled pendants.
Stored energy can cause coiled pendants to uncoil
quickly with considerable force.
• When inflating tires, use a tire cage, a clip-on
inflater, and an extension hose that permits standing
well away from the tire.
• Only use cleaning solvents that are non-volatile and
non-flammable.
• Do not attempt to lift heavy components by hand.
Use a hoist, jacks, or blocking to lift components.
• Use care while welding or burning on the crane.
Cover all hoses and components with non-
flammable shields or blankets to prevent a fire or
other damage.
• Disconnect and lock the power supply switch before
attempting to service high-voltage electrical
components and before entering tight areas (such
as carbody openings) containing high-voltage
components.
• When assembling and disassembling the booms,
jibs, or masts on the ground (with or without support
of the boom 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 (to include welding, cutting, or
burning of structural members or changing
pressures and flows of the air/hydraulic
components). Doing so will invalidate all warranties
and capacity charts and make the crane’s owner/
user liable for any resultant accidents.
WARNING
High-Pressure Hazard!
Prevent personal injury. Pressurized air, coolant, and
hydraulic oil can cause serious injury. Make sure all air,
coolant, and hydraulic lines, fittings, and components are
tight and serviceable:
• Do not use body parts (hands) to check for air and
hydraulic oil leaks.
• Use a soap-and-water solution to check for air leaks
(apply to fittings and lines and watch for bubbles).
• Use a piece of cardboard or wood to check for
coolant and hydraulic oil leaks.
DANGER
Battery Explosion Hazard!
Prevent serious injury. Avoid battery explosion:
• Do not smoke while performing battery maintenance.
• Do not short across battery terminals to check its
charge.
CAUTION
Prevent Machine Damage!
To prevent damage to crane parts, such as bearings,
cylinders, swivels, slewing ring, and computers, perform
the following steps before welding on the crane:
• Disconnect all cables from the batteries.
• Disconnect output cables at the engine junction box.
• Attach the ground cable from the welder directly to
the part being welded and as close to the weld as
possible.
Do not weld on the engine or any engine-mounted parts
(per engine manufacturer).
DANGER
Overhead Hazard!
Prevent personal injury. Do not go under the boom, jib, or
mast sections while the connecting bolts or pins are being
removed.
Boom, jib, or mast sections may fall.
