Installing the push arms on the blade (Models 150·1,
150·2!and 150·3 onIy) (Refer to Illust.'l8)
Attach the push arms to the blade with the
push arm bracket pins. These pins must be
installed so the pin locking hole lines up with
the hole in the push arm brackets on the blade.
Insert a 1/2 inch cap screw through each push
arm bracket and secure with a 1/2 inch lock nut.
Installing diagonal and upper struts (Models 150.1,
150·2/andlS(j·3 only) (Refer to Illust.18)
1. Adjust the upper struts so that the gap
between the shoulder of the eyebolt, clevis and
the upper strut body is 1-1/16 inch on each end.
(Refer to Illust. 20.)
2. As semble both the upper struts to the
blade and push arms. The upper strut pins
must be installed so the pin locking hole lines
up with the hole in the strut mounting lugs.
Insert a 1/2 inch cap screw through each
mounting lug and secure with a 1/2 inch lock
nut.
3. Position the strut locking pins through
the strut lock loops on the blade. This will
lock the struts so that the adjustment will not
change.

gap between the shoulder of the eyebolt and the
diagonal strut is one inch. (Refer to Illust.
