H. ATTACH HARDWOOD RISERS:
Place hardwood risers on frame to either side of hoist lower mount angles. Verify that top of
risers are flush with rear hinge pivot pads (see figures 5 or 6)
Note: Riser must sit flush on the top flange of frame. Locate risers to clear obstacles in
frame flange or drill clearance holes in risers.
I. ATTACH BODY TO REAR HINGE AND UPPER MOUNTS
1. Rear Hinge (see figures 5,6 and 7)
A. Position body on frame allowing approximately 3” of clearance between front
of body and other structure.
B. Make certain body is square with the frame and the rear hinge assembly
C. Securely weld rear hinges to body runsills (see figure 5,6, and 7)
2. Upper Mounts (see figures 14,15,and 16)
A. With body in down position there should be contact between body run sills and
risers
B. Raise hoist so upper mounts contact bottom of body runsills and shim between
upper and lower mounts. Weld shim to lower mount.
C. Weld upper mounts to body runsills. Position and weld upper mount supports
between upper mounts and body runsills. (see figure 14,15,or 16)
NOTE: On 520/625/630 hoists, it is important that the upper mounts are slid back toward
the scissor hinge as far as possible before welding to the body.
