BUCKET LINKAGE SHEARS
MAINTENANCE SAFETY
PROCEDURES
• Inspect the shear daily. DO NOT operate a poorly
maintained or damaged shear or major structural
damage could result.
•ALWAYS lower the shear to the ground before
leaving the cab. If it is necessary to work on a shear
off the ground, securely support the base machine
and shear. DO NOT support the shear on cinder
blocks, hollow tiles, or props that may crumble
under continuous load. DO NOT rely on the cylinder
to hold the shear in the air. If a control is moved or
hydraulic pressure is otherwise released, the shear
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 shear
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.
• 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 shear including safety glasses with
side shields, hard hat, steel toe shoes, gloves, and
hearing protection.
•DO NOT ATTEMPT REPAIRS YOU DO NOT
During maintenance of the shear, it is imperative
UNDERSTAND. ASK FOR HELP BEFORE
that the excavator is turned OFF to prevent injury.
STARTING IF YOU ARE UNSURE.
GENERAL 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.
Page 2 Section 5 Maintenance
3. Lubricate every four hours; follow the lubrication
schedule as outlined on page 5-7 .
4. Use the Inspection Checklists during shear
inspections to make sure all maintenance is
complete.
5. In extremely cold temperatures, work the shear
on lighter materials fi rst before working up to
heavier materials. This allows the shear to warm up
and makes it less susceptible to damage. DO NOT
operate at temperatures below -10º F (-230ºC).
6. 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.
7. 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.
8. The machined adjustment plates that are behind
the cutting blades in the lower shear have been
custom machined for each shear. If they should
come loose, be sure to replace them properly.
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 upper wear plate.
10. DO NOT preheat piercing tip in excess of 400°
F (200° C) when welding on a new replacement tip.
It is recommended that the piercing tip not be built
up and hardsurfaced more than once.
11. DO NOT weld or hard surface 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 or after 80 hours, whichever comes fi rst.
Regular blade rotation will keep blades square,
allowing for blade shimming.
13. DO NOT exceed bolt torque specifi cations (see
Dry Bolt Torque Chart on page 5-9).
14. DO NOT exert excavator weight on the jaws in
order to free them if they are jammed; consult your
LaBounty dealer or the LaBounty Customer Service
Department if this occurs.
