General Maintenance
1. Activate the truck engine and hydraulic sys-
tem, then lower the Hog Arm and blasting head
to the horizontal position, above the pave-
ment. Support the arm with a safety stand.
2. Deactivate the hydraulic system and place the
truck in the service position.
3. Remove the articulation safety pin and rotate
the Hog Head back until it rests against the
Hog Arm.
4. Remove the spray bar protector.
5. Place a straight edge across the bottom of the
wheels and below the spray bar to simulate the
pavement surface. Measure the distance from
the straight edge to the spray bar to determine
the standoff distance.
6.
Remove the safety pins and turn the adjust
-
ment handles to raise or lower the castor
wheels to achieve the desired distance from
the straight edge to the spray bar. Remember
that 1.5” (3.5 cm) is the standard standoff
distance from the spray bar to the pavement.
Increase the distance if required to clear road
obstacles. Make sure to turn each handle the
same number of revolutions to keep the blast
head level.
7. Cross check the measurement by placing the
straight edge across the other wheels. Read-
just the castor wheels as required to level the
blast head.
8. Install the spray bar protector and gasket.
9. Rotate the Hog Head to the horizontal position,
and remove the safety stand.
10.
Before starting operations, confirm proper
clearance by moving the blast head slowly over
a typical obstacle in the pavement on the cur-
rent job while monitoring the clearance. Make
additional adjustments if necessary.
11. Be alert for obstacles that are higher than the
standoff clearance during removal operations.
You must be prepared to avoid the obstacle or
stop the truck and adjust the standoff distance
to provide additional clearance.
CAUTION
• It is never acceptable to pass over obstacles in
the pavement surface that are high enough to
hit the shroud. Pavement obstacles can cause
severe damage to blast head components.
• Never allow the blast head to pass over debris.
• Never allow the blast head to pass over equip
-
ment or markers that can be damaged by the
shroud, spray bar or the blast from the water
jets.
• Always perform a test pass at the start of each
job to confirm adequate standoff clearance
before beginning normal removal operations.
