a safety zone by keeping bystanders and animals beyond a 100 foot
radius around the attachment when operating.
Inspect the Aachment
1. Inspect the attachment to be sure it is in working order. If the attach-
ment is damaged or not in working order, do not operate until it has
been repaired by a qualied technician.
Descripon
Theory of Operaon
The Grapple hydraulic hoses are connected to the loader front auxiliary
hydraulic couplers. The loader’s hydraulic controls are used to extend
and retract the hydraulic cylinders, which raise and lower the hooks to
hold the material in the attachment.
A - Hook
B - Removable Side
C - Cylinder Guard
D - Hydraulic Cylinder
E - Hydraulic Hoses
F - Step Area

20
Operang
