MSD 7R SHEARS
Page 2 Section 5 Maintenance
GENERAL RULES FOR
MAINTENANCE
1. Read the maintenance manual. Be sure all
maintenance personnel read and understand all
maintenance procedures before they attempt them.
2. Use factory approved parts. Use of parts that
are not factory approved may cause damage or
unnecessary downtime and void the shear warranty.
3. Lubricate daily; follow the lubrication schedule as
outlined on page 5-5.
4. DO daily inspection on blades, blade bolts, guide
blade, cylinders and wear surfaces.
5. Use the Inspection Checklists during shear
inspections to ensure all maintenance is complete.
6. In extremely cold temperatures, work the shear
on lighter materials fi rst before working up to heavier
materials. Doing so allows the shear to warm up and
makes it less susceptible to damage.
7. To get maximum life from the shear blades, they
can be rotated to utilize all four edges. Frequent
rotating allows the blades to wear evenly and will
increase their life.
8. DO NOT enter the pivot group of the shear
without fi rst consulting your dealer or the Stanley
LaBounty Customer Service Department. Improper
adjustment could cause shear damage and may void
the shear warranty.
9. DO NOT weld the guide blade into its blade seat.
The guide blade is needed for proper adjustment of
the shear. DO NOT allow excessive gap between
guide blade and front wear plate.
10. DO NOT preheat cutting tip in excess of
450º F (230º C) during build-up and hardsurfac-
ing procedures.
11. DO NOT weld or hardsurface across the grain of
the steel at any time. When hardsurfacing, DO NOT
exceed two passes of hardsurface rod.
12. DO NOT allow shear blades to wear excessively.
Rotate or replace the blades when edges have
rounded to approximately 1/4" (6 mm) radius.
13. DO NOT exceed bolt torque specifi cations. (See
Dry Bolt Torque Chart on page 5-5.)
14. DO NOT disconnect any hydraulic hoses or
fi ttings without fi rst relieving the excavator system
hydraulic pressure.
MAINTENANCE SAFETY
PROCEDURES
Before attempting any maintenance procedure, read
the entire Safety Manual carefully. If any question
arises regarding a safety or maintenance procedure,
contact your LaBounty dealer. For the nearest
LaBounty dealer, see the Contact Information at the
front of this manual.
• Inspect the attachment daily. DO NOT operate a
poorly maintained or damaged attachment or major
structural damage could result.
• ALWAYS lower the lift arms to the ground before
leaving the cab. If it is necessary to work on an
attachment off the ground, securely support the
machine and attachment. DO NOT support the
machine on cinder blocks, hollow tiles, or props that
may crumble under continuous load. DO NOT rely
on the cylinder to hold the attachment in the air. If a
control is moved or hydraulic pressure is otherwise
released, the attachment will drop. DO NOT work
under a machine that is supported solely by a jack.
• DO NOT attempt to alter or change the physical,
mechanical or hydraulic operation of the attachment
during the warranty period without fi rst consulting
Stanley LaBounty as this could invalidate the
Manufacturer’s Warranty.
• NEVER operate the machine if an unsafe condition
exists. Attach a “DO NOT OPERATE” tag to the
machine.
• If more than one person is working on a machine,
each must be familiar with the controls and aware
of what the others are doing. Before working on a
machine, BE SURE TO TAG THE CONTROLS SO
NO ONE ELSE WILL START IT.
• ALWAYS use two people when making checks with
the engine running—the operator at the controls
must be able to see the person doing the checking.
• Keep hands away from moving parts. NEVER
lubricate or work on a machine while it is moving.
• ALWAYS wear proper safety equipment when
maintaining the attachment including safety glasses
with side shields, hard hat, steel toe shoes, gloves,
and hearing protection.
• DO NOT ATTEMPT REPAIRS YOU DO NOT
UNDERSTAND. ASK FOR HELP BEFORE STARTING
IF YOU ARE UNSURE.
During maintenance of the attachment, it is
imperative that the excavator is turned OFF to
prevent injury
.
Refer to the proper maintenance procedure in
this manual before servicing the machine to
prevent injury or damage to the equipment.
