INTRODUCTION

14.
Avoid battery acid contact with skin and eyes. If contact
occurs, flush area with water and immediately consult a
doctor.
15.
Stop engine before refueling crane.
16.
Do not smoke or allow open flames in refueling area.
17.
Use a safety-type can with an automatic closing cap and
flame arrestor for refueling.
18.
Hydraulic oil can also be flammable. Do not smoke or
allow open flames in area when filling hydraulic tanks.
19.
Never handle wire rope with bare hands. Always wear
heavy-duty gloves to prevent being cut by broken wires.
20.
Use extreme care when handling coiled pendants.
Stored energy can cause coiled pendants to uncoil
quickly with considerable force.
21.
When inflating tires, use a tire cage, a clip-on inflater,
and an extension hose which permits standing well away
from tire.
22.
Only use cleaning solvents which are non-volatile and
non-flammable.
23.
Do not attempt to lift heavy components by hand. Use a
hoist, jacks, or blocking to lift components.
24.
Use care while welding or burning on crane. Cover all
hoses and components with non-flammable shields or
blankets to prevent a fire or other damage.
25.
To prevent damage to crane parts (bearings, cylinders,
swivels, slewing ring, computers, etc.), perform following
steps
before welding on crane
:
•
Disconnect all cables from batteries.
•
Disconnect output cables at engine junction box.
•
Attach ground cable from welder directly to part
being welded and as close to weld as possible.
Do not weld on engine or engine mounted parts (per
engine manufacturer).
26.
Disconnect and lock power supply switch before
attempting to service high voltage electrical components
and before entering tight areas (such as carbody
openings) containing high voltage components.
27.
When assembling and disassembling booms, jibs, or
masts on ground (with or without support of boom
rigging pendants or straps), securely block each section
to provide adequate support and alignment.
Do not go under boom, jib, or mast sections while
connecting bolts or pins are being removed.
28.
Unless authorized in writing by Manitowoc, do not alter
crane in any way that affects crane’s performance (to
include welding, cutting, or burning of structural
members or changing pressures and flows of air/
hydraulic components). Doing so will invalidate all
warranties and capacity charts and make crane owner/
user liable for any resultant accidents.
29.
Keep 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.
30.
Store tools, oil cans, spare parts, and other necessary
equipment in tool boxes. Do not allow these items to lie
around loose in 999 Operator cab or on walkways and
stairs.
31.
Do not store flammable materials on crane.
32.
Do not return 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.
33.
Perform a function check to ensure proper operation at
completion of maintenance or repair.
ENVIRONMENTAL PROTECTION
Dispose of waste properly!
Improperly disposing of waste
can threaten the environment.
Potentially harmful waste used in Manitowoc cranes includes
— but is not limited to — oil, fuel, grease, coolant, air
conditioning refrigerant, filters, batteries, and cloths which
have come into contact with these environmentally harmful
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 drain waste fluids into leak proof containers that
are clearly marked with what they contain.
•
Always fill or add fluids with a funnel or a filling pump.
•
Immediately wipe up any spills.
