cleaning the front grill area up to the head light (see Picture #49).

When the wheel reaches the front corner of the vehicle, the
SECONDARY ARM PIVOTS
and stars to
KNUCKLE
BACK
under the brush rotation combined with the
PRIMARY CYLINDER
pulling the arm back (see Picture #51).
After
the
SECONDARY ARM
starts to knuckle back, the
PRIMARY ARM
is pulling back on the secondary arm
allowing the wheel to brush along the entire side of the vehicle, profiling around mirrors and antennas. If the brush
becomes too sluggish while on the side of the vehicle, try closing (1/2 turn at a time) the
SECONDARY ARM
EXHAUST NEEDLE VALVE.
If the arm doesn’t knuckle back, try increasing the primary regulator air pressure or
decrease the secondary air pressure.

When
the primary arm reaches its initial resting position, the
PRIMARY LIMIT SWITCH
is then activated,
restarting
the three way valve, and applying pressure to the
SECONDARY ARM again
(See Picture #52)
.
The
secondary arm is now fully knuckled back and ready to extend and clean the rear area of the vehicle.
