About the Log Grapple Attachment
The log grapple attachment is intended for use in materials handling. The primary use of the log grapple
attachment is moving or skidding logs. Use of this equipment in any other manner is considered to be
contrary to the intended use of the attachment.
The load weight should never exceed 2,000 lbs. Damage to the attachment, prime mover, or operator
could occur if this is ignored.
Attaching the Log Grapple to the Prime Mover
NOTE: Before attempting to attach the log grapple to the prime mover, verify that all hydraulic couplings
are compatible.
WARNING –Improper attachment to the prime mover may cause personal injury.
CAUTION –All hydraulic connections must be clean and free of debris before making any connection.
1. Place the root grapple attachment on a level surface.
2. Position and align the prime mover to the rear of the attachment, within proximity of the front of
prime mover.
3. Insert and connect the prime mover into the attachment.
4. Connect the hydraulic lines from the attachment to the prime mover.
5. Close latches (or other locking mechanism) to secure the attachment to the prime mover.
6. Using the prime mover, raise the attachment and move the attachment to ensure hydraulic lines
are clear of air and operate properly.
CAUTION –Hydraulics should operate in an even and smooth manner. Hydraulic movement that is
not even and smooth may indicate that air is in the hydraulic lines.
7. Lower the attachment to ground level.
8. Inspect that the attachment is mounted properly and securely. If the attachment does not meet
this requirement, follow the instructions to remove the Root Grapple and re-attach using the
instructions above.
Removing the Log Grapple from the Prime Mover
WARNING –Improper disconnection may result person injury or damage to the attachment and prime
mover.
CAUTION –All hydraulic connections must be clean and free of debris before disconnection.
1. Using the prime mover, lower the attachment to the ground.
2. To prevent contamination, remove any dirt and debris from the couplings. Disconnect the
hydraulic connection between the attachment and the prime mover.
NOTE: Hydraulic connections must be disconnected before disengaging latches to prevent damage to
the prime mover or the attachment.
3. Disengage the prime mover latches (or other locking mechanism) from the attachment.
4. Move the prime mover from the attachment.

Operation and Maintenance
Equipment Inspection
It is recommended to inspect the equipment for damage and wear before use. Use the following list as a

or other structural flaws.
•Check that all latches or locks are closed.
•Check that all hydraulic fittings are tight and free of leaks
•Check that all hydraulic lines are free of leaks, holes, or cracks.
WARNING –Do not use hands to check for hydraulic leaks. Keep body parts away from leaking
hydraulic lines and couplings that are under pressure.
•Check that the tires on the prime mover are in good condition and have proper load
ratings.

There are 5 grease points on the log grapples. See exploded parts view below for each
location. The attachment does not need disassembled for greasing. However, you may
need to open or close the claws to allow for your grease gun to reach the zerk. Ensure
that the machine is turned off during service and that you support the lift arms with
lockout braces if the machine’s arms are lifted. Grease every 8 hours of use.
