GENERAL INSTRUCTIONS
I. Read Instruction Manual and Safety Rule s Carefully
This manual has been compiled to give the owner, operator, and mechanic,
information as to the care, operation, and maintenance of the machine. For
convenience this Instruction Manual has been written in sections. The first
page of each section lists the heading s contained in that section. Familiarize
yourself with the Instruction Manual so that you can easily locate the particu-
lar information you may need.
A capacity plate which shows the lifting limitations of the machine is mounted
inside the operator' s cab. Never exceed the loads and/or conditions stated.
The safety rule s included with this manual repre sent a minimum set of stan-
dards for safe machine operation, and every operator should be familiar with I
and follow them at all times.
Each machine has a specific serial number assigned to it so that it can be
readily identified. The serial number of your machine is stamped on a plate
which is mounted on the right hand machinery side frame. This serial number
should always be included in any correspondence with Bucyrus-Erie Company
or any of its distributors.
Every effort has been made to have this manual as complete as possible at
the time of printing. However, since Bucyrus-Erie Company reserves the
right to improve its products continually I change s may have been made that
will not be covered in this manual.

V. Machine Inspection and Maintenance
There is no substitute for preventive maintenance. A regular schedule of pre-
ventive maintenance should be set, so that any apparent troubles are found
before extensive damage is done to the machine.
Many critical components on the machines are subject to wear and other de-
terioration or damage which limit their useful life; thus, they are expendable.
When new, all such parts have a built-in reserve strength against unknown
conditions and reasonable loss of strength due to gradual deterioration. How-
ever if replacement is neglected, these parts can eventually reach a condition

where they become a safety hazard. Failure to maintain correct adjustments
of the various mechanisms to assure proper performance of the machine also
can be a safety hazard.
SINCE THE MACHINE MANUFACTURERHAS NO DIRECT CONTROL OVERTHE
FIELD INSPECTION AND MAINTENANCE, SAFETYIN THIS AREAIS THE RESPON-
SIBILITYOF THE USER.
Inspection - All machines in active service should be inspected at regular
intervals for proper adjustment of operating mechanisms, excessive wear or
deterioration of components, accidental damage and any other defects which
might be questionable as to safety. Any deficiences noted should be care-
fully inve stigated and determination made as to whether they constitute a
safety hazard. Inspection is vital to safe operation. It should be performed
by competent personnel and on a regular and systematic basis.
Inspection Frequency - Frequency requirements of inspection depend upon
numerous factors such as machine activity, severity of service, vulnerability
of parts to wear and damage and the extent to which parts may be deemed
critical in relation to safety. Inspection frequency can be divided into two
general categories as follows:
1. Daily to monthly intervals including observation during operation for any
defects which might appear between regular inspections.
a. All control mechanisms for maladjustment interferring with proper
operation.
b. All control mechanisms for excessive wear of components and con-
tamination by lubricants or other foreign matter.
c. All safety device s for malfunction.
d. Deterioration or leakage in air system.
e. Crane hooks with deformations or cracks.
f. Rope reeving for noncompliance with crane manufacturer's recommen-
dations.
g. Electrical apparatus for malfunctioning. signs of excessive deteriora-
tion, dirt, and moisture accumulation.
2. One to twelve month intervals. A complete machine inspection including
items as in 1 above and in addition the following:
a. Deformed, cracked, or corroded members in the crane structure ancl
boom.
b. Loose bolts or rivets.
c. Cracked or worn sheaves and drums.
25-8
X-2172
1-5
Rev. 7-73

d. Worn, cracked or distorted parts such as pins, bearings, shafts,
gears, rollers and locking device s ,
e. Excessive wear on brake and clutch system parts, linings, pawls,
and ratchets.
f. Load, boom angle, and other indicators over their full range, for any
significant inaccuracies.
g. Gasoline I die sel, electric, or other power plants for improper perfor-
mance or noncompliance with safety requirements.
h. Exce ssive wear of chain-drive sprockets and excessive chain stretch.
j. Crane hooks. Magnetic particles or other suitable crack detecting
inspection should be performed at least once each year.
k, Travel steering, braking, and locking device s, for malfunction.
Maintenance - Preventive maintenance programs based on the recommenda-
tions contained in this manual should be established. However, due to the
wide variation in job applications, severity of service, machine activity and
environment it is impossible for us to develop a single, complete standard
procedure which will fit all applications. Therefore such programs should be
developed by trained and experienced personnel, responsible for maintenance
of the machine, by adjustment and extens ion of our general recommendations,
to suit the particular needs.
Adjustments, Replacements & Repairs - Any conditions, disclosed by the
inspection requirements above, which are considered to constitute safety
hazards should be corrected before operation of the machine is resumed, to
assure that the equipment will always be operated in a safe condition.
Replacement Parts - It is recommended that all replacement parts be obtain-
ed from the original equipment manufacturer in order that the strength and
quality of the original machine may be maintained.
Lubrication - Regular and systematic lubrication should be maintained on
the machine, in accordance with the lubrication charts and general recom-
mendations contained in this manual. All machinery should be stopped while
lubricating except in cases where the lubrication system is designed for safe
application while the machinery is in motion. Any guards or panels which
must be removed for access to some points for lubrication or inspection
should always be replaced before resuming operation.
Maintenance Tools - Routine maintenance tools should be available at all
times.

II
Fire Extinguisher - A carbon dioxide or dry chemical hand fire extinguisher
should be kept in the operator's cab at all times.
Remember that the matter of keeping bolts and nuts tight is just as much an
item of maintenance as lubricating or adjusting the machine. A bolted connec-
tion which is not quite tight will quickly pound itself into a loose and danger-
ous connection.
A weld which has cracked due to excessive strain can be easily repaired by
"V-ing" it out and rewelding, but if the crack is allowed to go, it may spread
so much that proper alignment of the parts is lost. A satisfactory repair is
then hard to make.
An item of maintenance not to be overlooked is cleanliness. Clean and paint
the machine as part of your regular preventive maintenance schedule.
Operation - In general, established operating safety rule s where applicable
should be observed in performing operating functions. Operating safety rule s
are found in sources such as the following:
CLEAN IT FIRST - KEEPCLEAN FROM STARTTO FINISH.
VI. Machine Application and Operation
General - This is probably the most important area relative to safety since
it involves the greatest frequency of exposure to hazards. The operator
should be fully competent physically, mentally and emotionally to unders tand
and apply established operating safety rules. He should be able to exercise
good judgment in dealing with the many situations which cannot be anticipa-
ted and covered herein. SINCE THE MANUFACTURERHAS NO DIRECT CONTROL
OVERMACHINE APPLICATION AND OPERATION, CONFORMANCE WITH GOOD
SAFETYPRACTICE IN THIS AREAIS THE RESPONSIBILI'IY OF THE USER OR HIS
OPERATING PERSONNEL.
Application - Only machine s of proper rated capacity and type should be
assigned to the job to be done. Anything less constitutes a safety hazard.
1. Occupational Safety and Health Act of 1970, as amended.
2. ANSI Standard Safety Code for Crawler, Locomotive and Truck Cranes,
ANSI 830.5.
3. Power Crane and Shovel Association - "60 Rules on Safety" •

X-2172

Rev. 7-73

4. This Instruction Manual.
It is recognized that written rules cannot cover all situations which might be
encountered on the job. To meet such unanticipated situations the operator
must be able to supplement his own rules based on good judgment.
Capacity Ratings - Manufacturers' ratings should never be exceeded. The
stipulations pertinent to these ratings should always be carefully observed.
Under some conditions even the full standard capacity ratings cannot be
recommended and must be adjusted downward to compensate for special
hazards.
Rating Based on Structural Competence - As the shorter rated radii are
approached in the lifting operation the load required to tip the machine in-
creases very rapidly to a point where the actual tipping load is almost unlim-
ited. Rated loads based on excessive tipping loads cannot be covered by
adequate design factors since this would result in excessive machine weight
and limitation of the machine's usefulness. Consequently, some of the rat-
ings shown on the chart may be based on machine's structural compe te nce
rather than stability, in which cases the full use of stability in lifting loads
is not intended or approved. It is therefore unsafe to apply any load, which
is greater than the rated load shown on the chart for that radius.
Counterweight - The maximum counterweight approved by the manufacturer
for use on a given machine should never be exceeded. Unauthorized addi-
tion of counterweight in the field constitutes a safety hazard in two ways.
First, the higher loading of machine parts has not been taken into account
in the design. Second, the backward stability margin built into the machine
for the user's protection could be reduced beyond that considered safe
practice.
Level Machine - All load ratings are based on levelness of the machine in
both directions. Any deviation from this condition introduces a safety
hazard, the degree of which depends upon the amount of deviation, and must
be taken into account by the operator in loading and handling the machine.
Unattended Machines - Before leaving his control station the operator should
rest the attachment on ground, place controls in neutral position and set all
locking devices as necessary to secure the machine.
Ground or Support Conditions - Capacity ratings are based on the condition
of a firm supporting surface under the machine. Operating personnel should
consider and allow for unusual conditions, since yielding of the supporting
surface during operation may be a hazard.

Operation Near Electric Power Lines - Consult references listed above or
possible local codes.
Hand Signals - Included in this manual.
Operation With Attachment or Counterweight Removed - Operation including
swinging, traveling or transporting of machine with attachment removed, but
with counterweight in place, or conversely, counterweight removed and attach-
ment in place, may involve condition of dangerous instability. Such operation
should be performed only if proper precautions are taken to prevent machine
from tipping.
VII. Rope Inspection, Replacement, and Maintenance
Inspection - All running rope s in continuous service should be visually in-
spected once every working day. A thorough inspection of all ropes in use
shall be made at least once a month and a full written, dated, and signed
report of rope condition kept on file where readily available. All inspections
shall be perfonned by an appointed or authorized person. Any deterioration,
resulting in appreciable loss of original strength, such as described below,
shall be carefully noted and determination made as to whether further use of
the rope would constitute a safety hazard:
1. Reduction of rope diameter below nominal diameter due to los s of core
support, internal, or external corrosion or wear of outside wires.
2. A number of broken outside wires and the degree of distribution of con-
centration of such broken wires.
3. Worn outside wires.
4. Corroded or broken wires at end connections.
5. Corroded, cracked, bent, worn, or improperly applied end connections.
6. Severe kinking, crushing, cutting, or unstranriing.
Heavy wear and/or broken wires may occur in sections in contact with equal-
izer sheaves or other sheaves where rope travel is limited, or with saddles.
Particular care shall be taken to inspect ropes at the se locations.
All rope which has been idle for a period of a month or more due to shut down
or storag€ of a crane on which it is installed shall be given a thorough
25-B
X-2172
1-9
Rev. 7-73

inspection before it is placed in service. This inspection shall be for all types
of deterioration and shall be perfonned by an appointed or authorized person
whose approval shall be required for further use of the rope. Awritten and
dated report of the rope condition shall be filed.
Particular care shall be taken in the inspecting of non-rotating rope,
Replacement - No precise rules can be given for determination of the exact
time for replacement of rope, since many variable factors are involved.
Safety in this respect depends largely upon the use of good judgment by an
appointed or authorized person in evaluating remaining strength in a used
rope after allowance for deterioration is disclosed by inspection. Safety of
rope operation depends upon this remaining strength.
Conditions such as the following should be sufficient reason for questioning
rope safety and for consideration of replacement:
1. In running ropes, six randomly distributed broken wires in one lay or
three broken wires in one strand in one lay.
2. Wear of one-third the orig inal diameter of outside individual wires.
3. Kinking, crushing, bird caging, or any other damage resulting in distor-
tion of the rope structure.
4. Evidence of any heat damage from any cause.
5. Reductions from nominal diameter of more than:
a. 3/64 inch for diameters to and including 3/4 inch.
b. 1/16 inch for diameters 7/8 inch to 1-1/8 inches inclusive.
c. 3/32 inch for diameters 1-1/4 to 1-1/2 inches inclusive.
6. In standing rope s, more than two broke n wire s in 0 ne lay in sections
beyond end connections or more than one broken wire at an end connec-
tion.
In order to establish data as a basis of judging the proper time for replace-
ment, a continuing inspection record shall be maintained.
Maintenance - Rope shall be stored to prevent damage or deterioration.
Unree linq or uncoiling of rope shall be done as recommended by the rope
manufacturer and with extreme care to avoid kinking or inducing a twist.

Before cutting a rope, se iz mq s shall be placed on each side of the place
where the rope is to be cut to prevent unlaying of the strands. On preformed
rope, one seizing on each side of the cut is required. On nonprcforme d ropes
of 7/8 inch diameter or smaller I two seizing s on each side of the cut arc
required I and for nonpreformed rope of 1 inch diameter or larger I three se izing s
on each side of the cut are required.
During installation care shall be observed to avoid dragg ing of the rope in .
dirt or around objects which will scrape I nick I crush I or induce sharp bends
in it.
Rope should be maintained in a well lubricated cond ition. It is important
that lubricant applied as part of a maintenance program shall be compatible
with the original lubricant and to this end the rope manufacturer should be
consulted. Those sections of rope which are located over sheaves or other-
wise hidden during inspection and maintenance procedures require special
attention when lubricating rope. The object of rope lubrication is to reduce
internal friction and to prevent corrosion. Periodic field lubrication is par-
ticularly important for non-rotating rope.
When an operating rope shows greater wear at well defined localized areas
than on the remainder of the rope I rope life can be extended in cases where
a reduced rope length is adequate I by cutting off a section at one end I and
thus shifting the wear to different areas on the rope.
VIII. Handling the Load
Size of Load - No crane shall be loaded beyond the rated load I except for
test purposes.
When loads which are limited by structural competence rather than by stability
are to be handled I the person re spons ible for the job shall ascertain that the
weight of the load has been determined within plus or minus 10 percent before
it is lifted.
Attaching the Load - The hoist rope shall not be wrapped around the load.
The load shall be attached to the hook by means of sling s or other approved
devices.
Moving the Load - The individual directing the lift shall see that:
1. The crane is level and where nece s sary blocked properly.
25-B
X-2l72
1-11
Rev. 7-73

2. The load is well secured and properly balanced in the sling or lifting
device before it is lifted more than a few inches.
Before starting to hoist/ note the following conditions:
1. Hoist rope shall not be kinked.
2. Multiple part lines shall not be twisted around each other.
3. The hook shall be brought over load in such a manner as to prevent
swinging.
4. If there is a slack rope condition/ it should be determined that the rope
is properly seated on the drum and in the sheaves.
During hoisting care shall be taken that:
1. There is no sudden acceleration or deceleration of the moving load.
2. Load does not contact any obstructions.
Side loading s of booms shall be limited to freely suspended loads. Cranes
shall not be used for dragging loads sideways.
The operator shall not hoist/ lower / swing / or travel while anyone is on the
load or hook.
The operator should avoid carrying loads over people.
On truck mounted cranes/ no loads shall be lifted over the front area except
as approved by the crane manufacturer.
The operator shall test the brake s each time a load approaching the rated load
is handled by raising it a few inches and applying the brakes.
Outriggers shall be used when the load handled at that particular radius ex-
ceeds the rated load without outriggers as given by the crane manufacturer.
Where floats are used they shall be securely attached to the outriggers.
Neither the load nor the boom shall be lowered below the point where less
than two full wraps of rope remain on their respective drums.
When two or more cranes are used to lift one load/ one designated person
shall be re sponsible for the operation. He shall analyze the operation and
instruct all personnel involved in the proper positioning / rigging of the load
and the movements to be made.
In transit the following additional precautions shall be exercised:
1. The boom shall be carried in line with the direction of motion.

2. The upper works shall be secured against rotation, except when ne-
gotiating turns when there is an operator in the cab or the boom is
supported on a dolly.
3. The empty hook shall be lashed or otherwise restrained so that it cannot
swing freely.
Before traveling a crane with load, a de signated person shall be responsible
for determining and controlling safety. Decisions such as position of load
boom location, ground support, travel route, and speed of movement shall
be in accord with his determinations.
A crane with or without load shall not be traveled with the boom so high that
it may bounce back over the cab.
When rotating the crane, sudden starts and stops shall be avoided. Rotation-
al speed shall be such that the load does not swing out beyond the radii at
which it can be controlled. A tag or restraint line shall be used when rotation
of the load is hazardous.
When a crane is to be operated at a fixed radius, the boom hoist pawl or other
positive locking device shall be engaged.
Holding the Load - The operator shall not leave his position at the controls
while the load is suspended.
No person should be permitted to stand or pass under a load on the hook.
If the load must remain suspended for any considerable length of time, the
operator shall hold the drum from rotating in the lowering direction by acti-
vating the positive controllable means of the operator's station.
IX. Safety Precautions
1. Always correct any faulty conditions that may cause damage to the
machine or result in personnel injury.
2. Do not allow open flame or smoking around flammable material or when
servicing the batterie s.
3. When servicing batterie s take care not to get electrolyte on skin,
clothing or in eye s ,

4. Do not fill fuel tank while engine is running. Be sure there are no open
flames or exposed heated parts that can ignite fuel vapors while tank is
being filled. Keep fuel nozzle in contact with tank being filled, or
provide a ground to prevent static sparks from igniting fuel.
5. Before starting engine, be sure all operating levers and foot pedals are
in neutral.
6. Stop all other operation when cleaning, adjusting, or lubricating the
machine.
7. When making adjustments or cleaning machine, be sure the engine
clutch is disengaged unless specific adjustments require engagement.
8. When adjusting the eng ine clutch, the engine must not be running.
9. Engage swing brake before propelling. Watch for low overheads and
narrow side clearances during propelling. Look out for power lines.
Avoid soft ground. Cross railroad tracks slowly.
10. Keep machine free of grease, oil, ice, and mud to prevent slipping and
falling.
11. Except for specifiC adjustments which must be made while the engine is
running, do not work on engine while in operation.
12. Use extreme caution in releasing the radiator cap when the engine has
been overheated. If possible, wait unt il the engine is cool before re-
moving the cap.
13. In severe cold weather, do not touch any metal parts of the machine with
exposed flesh, as the flesh can stick to the metal and cause severe in-
jury •
14. Reduce throttle when maneuvering in tight quarters.
CAUTION
This equipment must not be operated
in a location where any of its parts or
load can be brought closer than ten
(10) feet to power lines, unless cur-
rent has been shut off and the lines
grounded.
