8. Next, align the mount holes on the pump and the manifold with the
holes in the brackets located on the A-frame. When installed correctly,
the manifold will be located at the front of the A-frame closest to the
pivot beam.
CAUTION: When installing the manifold between the mount
brackets on the A-frame, hold the manifold at the sides of
the block. Never handle the manifold by the wire lead coils.
Doing so can cause a solenoid cartridge to bend, causing
the cartridge to stick when activated.

Installing The Manifold Adapters
There are a total of 4 hydraulic adapters to install.
All of the adapters can be found packaged with
the manifold assembly. Remove the protective
stretch wrap from the manifold in a clean area.
DO NOT let any foreign objects enter into the
open ports. The valves can become contaminated
and greatly hinder the plow's performance.
Review the table on page 33 for proper torque
specifications.
When installing the manifold between the mount
brackets on the A-frame, DO NOT handle the
manifold by the wire lead coils. The solenoid
cartridges can bend, causing them to stick when
activated. Always carry the manifold by the sides
of the aluminum block.
