1. Foreword
1.1 Introduction
Congratulations on your choice of a Wallenstein Log Grapple!
The Wallenstein LXG520R Log Grapple is suitable to mount
on small excavators in place of the bucket. It is designed for
loading / carrying logs in a small-scale timber industry or
landscaping business.
The utility log grapple requires two auxiliary circuits from the
main control valve to open, close, and rotate. If two circuits
are not available, a selector valve kit must be installed. The
mounting bracket and whip hoses are not included with the log
grapple and must be supplied by the customer.
Safe, efficient and trouble-free operation of this Wallenstein
product requires that anyone using or maintaining the machine
reads and understands the Safety, Operation, and Maintenance
information contained within the Operator's Manual.
Keep this manual handy for frequent reference and to pass on
to new operators or owners. Call your Wallenstein dealer or
the Distributor if you need assistance, information or additional
copies of the manual.
