2.2 Hog Head
Overview
The Hog Head is a single blasting head design
mounted on the Ground Hog chassis. Front and
rear castor wheels support the head at a preset
height to prevent the spray bar from contacting
the pavement.
The term “Standoff” refers to the height of the
spray bar above the pavement. The standoff dis -
tance is set by adjusting the wheels that support
the Hog Head. Standoff directly affects removal
performance and should be checked periodically
and adjusted as required.
The factory preset standoff distance is 1.5” (3.5
cm) from the spray bar to the pavement. Spac-
ers on each caster adjust the height of the Hog
Head. Adjustment may be required to maintain
proper clearance by adding spacers as the castor
wheels wear.
Large wing nuts on the caster support arms allow
the caster assemblies to be rotated in and out.
The caster assemblies can be rotated parallel to
the handle to reduce the width of the Ground Hog
for storage or to allow the Hog Head to get close
to curbs and walls. Move the caster assemblies
out to a 45 degree angle to provide maximum
stability for most operating situations. Make sure
to tighten the wing nuts securely once the caster
assemblies are in the desired position.
Wear Brush
A wear brush clamped to the blasting head shroud
provides a partial seal between the blasting head
and pavement. The wear brush regulates vacuum
air flow into the shroud and reduces the amount
of debris and water exiting the blasting head dur-
ing operations. The wear brush is an important
safety feature of the blasting head system. It must
be installed properly and adjusted or replaced as
necessary.
