OPERATIONAL SAFETY
IMPORTANT: Concrete and masonry products contain silica sand.
Quartz, which is a form of silica and the most common mineral in the
Earth’s crust, is associated with many types of rock.
Some activities that may have silica dust present in the air include
demolition, sweeping, loading, sawing, hammering, drilling or planing of
rock, concrete or masonry.
It is recommended to use dust suppression (such as water) or dust
collection (such as a vacuum) along with personal protective equipment
if necessary during the operation of any attachment that may cause high
levels of silica dust.
Prioritized Oil Flow
operations or high reach conditions.
Emergency Situations
Unsafe Conditions
Do not operate if an unsafe condition exists. Stop operation immediately, shut down the machine
and report the unsafe condition to the proper authority. Equipment operation and maintenance
sense while operating and be alert to unsafe conditions.
Crystalline Silica Dust
It is recommended to use dust suppression, dust collection and if necessary, personal protective
equipment during the operation of any attachment that may cause high levels of dust.
!DANGER
Exposure to respirable crystalline silica dust along with
other hazardous dusts may cause serious or fatal
respiratory disease.

!WARNING
Using your Genesis attachment in unauthorized
applications may create an unsafe situation and will void
the warranty.
Process Material Safely
• Do not process hardened steel material such as tool steel, railroad rail, axles, springs,
machined parts or high-strength material. Hardened/high-strength material breaks, rather than
your Genesis attachment and base carrier hydraulic systems.
• Do not operate any functions of the carrier while cutting or crushing with your attachment,
including boom and drive functions.
• Do not pull down structures with your Genesis attachment. Doing so may cause falling debris
or material to break free and exceed the capacities of the carrier, causing a tipping hazard and
rotation component failures.
• Do not use rotation to pry or break material. Doing so exerts high back-driving forces and
spikes to the rotation circuit components that cannot be cushioned hydraulically. It may also
cause motor and gearbox failures. The rotator should only be used for positioning an
attachment.
• Do not process pressurized containers unless the main valve has been removed and you are
absolutely certain the container is empty.
• Do not process spring loaded brake chambers and automotive struts as the release of
compressed springs is extremely dangerous. Nothing made of spring material or containing
springs should be processed.
Lift the Load Safely
• The hydraulic system has been preset and tested by your dealer. Do not alter hydraulic set-
tings without consulting an authorized Genesis dealer or the Genesis Service Department.
Doing so will void the warranty and may cause structural damage, accidents or tipping.
• Make sure the load is held securely in the jaws. Do not move a loaded attachment if load is
loose or dangling. Make sure the load is pinched between the jaws – never cradle a load.
• For greater stability, knuckle the attachment to bring the load closer to the center of rotation
(center of gravity) while lifting. Use extra caution during reaching to avoid tipping.
Place the Load Safely
• Do not move the attachment, or anything held in the jaws, over people, equipment or
buildings. Place the load gently. Do not throw or drop the contents.
• Operate the controls smoothly and gradually. Jerky controls are hazardous and may cause
damage to the carrier.
•
• Never substitute pins or bolts. Use factory supplied pins. Replace all bolts with the same size
and grade. Failure to do so may cause serious injury or death.
• Use your Genesis attachment only as directed in this manual. Do not use the attachment to lift
and move other objects. Doing so may cause instability and tipping.

MAINTENANCE/TRANSPORT LOCK BOLTS
GRX demolition tools ship from the factory with lock bolts installed in the body and cylinder lock
pins as show below.
The lock bolts are to be installed any time the tool is transported or maintenance is performed to
prevent inadvertent lock pin movement during these operations.
Remove the lock bolts prior to normal operation.

ROTATION LOCK
Rotation (transport) locks are installed at the factory to allow the bracket to be shipped with the
from the truck and mounting it to the excavator.
Rotation locks MUST be removed before operating the attachment to prevent rotation
system damage.
The rotation locks are located inside the small bolt covers for the slewing ring and marked with
threaded into the rotation lock for removal.
There are TWO locks in every attachment, one on either side of the bracket. In some cases, one
of the port blocks may need to be removed to access the rotation lock. The rotation locks and red

ATTACHMENT INSTALLATION
Preparation of the excavator prior to attachment delivery will make installation safer and
easier. Contact Genesis or your Genesis dealer for assistance.
Dual-Pump Flow
An excavator typically has two hydraulic pumps that supply oil to its main control valve, which
Summating is the preferred method of achieving maximum speed to an attachment. However,
interchanging the stick and bucket circuits may also substantially increase speed.
an auxiliary circuit spool to the stick circuit helps reduce back pressure in the system and speed

depending on whether the bucket and auxiliary are on separate sides of the main valve and
whether the auxiliary circuit can be proportionally controlled by teeing into the bucket pilot control
circuit.
The auxiliary circuit must also be capable of proportionally controlling pump initiation on the
gradually increasing or decreasing, which can cause sharp, damaging spikes in the hydraulic
circuit.
If excavator circuits are electronically controlled, it may be necessary to reduce the spool shift and
pump initiation in the excavator software to take spiking out of the circuit when changing
attachment cylinder direction from full extend or full retract.
which in turn slows how the spool shifts and the pumps stroke up.

The attachment is usually shipped in an upright position. Extreme care must be used when
inverting the attachment for installation.
Follow the excavator OEM’s removal and safety instructions to remove the bucket or other stick
attachments.
Blocking may be required to raise the mounting bracket into
proper position.
Track the excavator to the attachment with the jaws facing the
operator. Lift the excavator stick over the attachment,
carefully positioning the stick tip connection with the
attachment mounting main pivot bore. Pin the excavator stick
to the attachment.
Slowly raise the boom to lift the attachment, allowing the
cylinder pivot connection to come within range of the
excavator cylinder stroke.
Extend the excavator cylinder until the power link bore lines
up with the cylinder pivot connection. Pin the excavator
cylinder to the attachment.
Crowd and extend the attachment, checking closely to make sure there is no interference between
the bracket and hard lines. Also check for interference between the cylinder and boom/stick.
Install excavator hydraulic hoses, supply and return, from the stick tip to the attachment manifold
blocks. See page 23 for electrical installation.
The stick and bucket circuits are oriented as to rod and bore sides of their respective cylinders. Be
sure to connect rod-to-rod and bore-to-bore when connecting a circuit to the attachment. When
these are reversed, extra pressure is needed to open the jaw, which pulls down the engine,
de-strokes the pumps, increases jaw cycle time, creates high oil temperature and burns more fuel.
The attachment must be vertical before putting oil into it or an air lock in the regen valve may
prevent the jaw from opening.

Be sure hydraulic pressure is relieved before disconnect-
