Page 8: Check The Equipment
Stability Your Genesis attachment is sized for carrier stability. However, improper operation, faulty maintenance or unauthorized modifications may cause instability. 3 Know the working ranges and capacities of the carrier to avoid tipping. -
Page 9: Know The Work Area
3 Slowly operate all functions to check for proper operation and to bleed air from the hydraulic system. To shut down: 3 Return your Genesis attachment to a rest position on the ground. 3 Shut off the carrier engine. 3 Work controls in all directions to relieve hydraulic pressure, per excavator manufacturer’s instructions. -
Page 10: Safely Operate Equipment
3 A heavy load can cause equipment instability. Use extreme care during travel. Slow down on turns and watch out for bumps. The equipment may need additional counter-weights to counterbalance the weight of the attachment. Genesis GHG 75-125 Handling Grapple © 2023 Genesis Attachments, LLC... -
Page 11: Transporting The Attachment
Current in high voltage lines may arc some distance from the wire to a nearby ground. Keep all parts of the machine at least 50 feet (16m) away from power lines. © 2023 Genesis Attachments, LLC Genesis GHG 75-125 Handling Grapple 11... -
Page 12: Use Care With Hydraulic Fluid Pressure
Allow hydraulic components to cool before working on them. Use appropriate protective clothing and safety equipment. If burned, seek immediate medical attention. Genesis GHG 75-125 Handling Grapple © 2023 Genesis Attachments, LLC... -
Page 13: Prioritized Oil Flow
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. © 2023 Genesis Attachments, LLC Genesis GHG 75-125 Handling Grapple 13... -
Page 14: Process Material Safely
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. -

Page 16: Maintenance Safety
Do not exceed bolt torque specifications. See the Genesis Fastener Manual. Do not weld on structural components without consulting Genesis. Doing so may cause structural failure and void the warranty. Do not operate an attachment without the case-drain line properly installed if the attachment uses a rotation system that requires a case drain. - Page 17 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. © 2023 Genesis Attachments, LLC Genesis GHG 75-125 Handling Grapple 17...

Page 33: Hydraulic Start-Up
HYDRAULIC START-UP Genesis grapples are designed to operate under full excavator pressure or up to 5000 PSI. Due to these high pressures, it is important that air is bled from the cylinder after installation. Failure to follow these procedures could result in cylinder seal damage and/or excavator hydraulic system damage. -
Page 34: Hydraulic / Rotation Maintenance
This may result in serious personal injury and damage to equipment. Improper torques will also cause uneven wear on the slewing ring. See the Genesis Fastener Manual for proper bolt torque specifications. Grease Slewing Ring Rotating components must be greased daily. -
