MSD SABER SERIES SHEARS
14.
DO NOT
close the shear on a structure and
reverse the excavator in an attempt to pull down
material. This is not only dangerous, but will likely
damage the excavator and shear.
15.
Avoid collision of the boom or shear, especially
when working with limited visibility or inside
buildings. Know the height and reach of the shear
during operation, transport, and when swinging the
excavator.
16.
Use machine swing for positioning only.
DO
NOT
use the shear as a jack hammer or wrecking
ball.
17.
Avoid contact between boom arm or shear stick
and overhead obstacles when you operate, move, or
haul the machine.
18. DO NOT
alter factory preset hydraulics of the
shear or vary from the excavator manufacturer
specifi cations. This may void the warranty.
19.
DO NOT
shear high tensile steel such as railroad
rail, spring steel, axles and some types of wire as
blade, Saber Tip, and/or upper damage will result.
This type of material breaks when processed and
can become a projectile which could cause injury or
death.
20.
To prevent bending the upper shear,
DO NOT
attempt to shear material stuck through the lower
jaw.
21.
Before attempting to shear thin material, make
sure that the shear blades are sharp and properly
adjusted. Otherwise, such material may become
jammed in the shear blades.
22.
The lifting lugs are to be used for shipping and
installation. They are not for use in cable-hung
applications.
23.
The shear rotation function is for positioning only.
DO NOT
use it for bending, breaking or prying.
24.
DO NOT
use the force of the excavator to force
the shear into a pile.
25.
DO NOT
apply excavator force or weight at
either end of the upper shear in an attempt to un-
jam the shear or to cut materials that are too large
for the shear.
GENERAL RULES FOR SAFE
OPERATION
1.
Read the Operator’s Manual for the base machine
on which the shear is mounted.
2. KNOW
the capacity of the excavator and its
attachments.
DO NOT
overload the machine or
serious injury could result. The attachment may
have altered the base machine’s lift capabilities.
3.
It is required that a Falling Objects Protection
Structure be installed surrounding the excavator cab
for all material handling applications.
4.
The shear is for processing materials.
DO NOT
use the attachment for unapproved purposes or
warranty may be voided.
5. DO NOT continuously
process oversized
materials by forcing them into the shear throat with
the downward force of the excavator. This practice
is detrimental to the life of the shear and is strongly
discouraged.
6.
If the shear stalls during processing, scale back
the amount of material being processed at one time.
Continuously overloading the shear and cycling
the excavator to full system pressure can cause
overheating and have adverse effects on the shear
and the excavator hydraulic system.
7.
Whenever possible, cycle the shear cylinder
completely during processing. Fully opening and
closing the shear allows more hydraulic fl uid to
circulate through the system to help prevent
overheating.
8.
Inspect and lubricate the shear daily. Tighten
any loose bolts or fi ttings to the proper torque as
specifi ed in this manual.
9.
Maintain a safe distance and avoid contact
between the excavator and the shear or any
material held by the shear jaws.
10. NEVER
leave the shear suspended or pass it
over people, occupied vehicles, or buildings.
11.
When working in confi ned spaces, keep a
watchful eye on exposed parts, such as cylinder
rods and hoses, to avoid damage.
12.
Maintain at least 15 feet (5 meters) between the
shear and any nearby power lines.
13. ALWAYS
lower the shear to the ground and turn
the base machine off when leaving the machine
unattended.
