Instructions for
the 600 Series
Finger Wheel Rakes
These instructions provide details for unpacking and
setting up the 600 Series Finger Wheel Rakes. This
document should remain with the machine in the
manual packet. A copy of this document should be
retained by the dealer.
GENERAL INFORMATION
The 600 Series Finger Wheel Rakes are shipped in
varying stages of assembly. The following instructions
provide illustrated details of how to set up the 600 Series
Finger Wheel Rakes. Recommended setup is as follows:
Unless otherwise noted, the standard fastening
procedure is to secure two parts with a cap screw and
lock nut. A part with a mounting slot should be secured
with a plain washer against the slotted surfaces. Lock
nuts are sometimes used to prevent two parts from
separating but still allow one part to move or rotate next
to the other. Attaching hardware, if it will require
installation in the path of material flow, should always
be installed with the head of the screw on the same side
of the part that will be in contact with the material.
SETUP
1. Implement is shipped disassembled in wooden
crates. Approximate assembly time is between
15-25 hours, depending on what options are to be
installed. The majority of the fasteners are metric.
Fig. 1
IMPORTANT: Use only metric tools for metric
fasteners.
2. Select an area that has adequate space for parts
layout and machine assembly. Remove all parts
from the crate and lay them out in assembly order
according to Fig. 2.
