4. USING THE GRAPPLE BUCKET
When attaching the grapple bucket for the first time, make sure it is compatible with the base machine by following
the instructions below. Always check the compatibility when attaching the collecting sweeper to a new base machine.
4.1. Attaching the grapple bucket to the base machine
The grapple bucket is attached to the base machine by welded or bolted quick hitches. The machine is connected to
connected to a hydraulic system.
Before using the grapple bucket, MAKE SURE
all locking cotters are secured and intact.
When coupling grapple bucket to the base machine, please pay attention to the instructions on the use of the base
machine.
1. Make sure that the attachment and the base machine are compatible in terms of mechanical solutions, hydraulics
and electricity.
2. Apply parking brake. The grapple bucket is attached to the coupler on the base machine. Attach the grapple bucket
to the base machine, and make sure the locking cotter are secured.
3. Turn off the base machine and make sure the parking brake is applied.
4. Make sure there is no pressure in the base machine hydraulic system. When connecting, always make sure the
hydraulic connectors are clean and the hoses are intact.
5. Check carefully the attachment’s, the base machine’s and the fitting’s trajectory for collision. Make sure that the
needed space for hydraulic hoses and -attachments is adequate. Check that the brush roll rotates outwards from the.
If not, switch hoses in the base machine.
6. During first hours of operating the attachment, bolts, nuts and connectors might loosen up. Retighten them after
the first day of operating the attachment.
5. OPERATING THE GRAPPLE BUCKET
Check following before using the grapple bucket:
- Grapple bucket is installed properly to the base machine
- All locking cotters are in place
- Hydraulic hoses are attached properly
- Hoses are intact
- There are no oil leaks in attachment
- All functions are in order
- Learn the functions of the grapple bucket in an enclosed area before actual usage.
- Observe all unusual activity and oil leaks when operating the grapple bucket.
