Snorkel AB50JRT - Manual (Page 80)

❑ Foam Filled Tires
Foam filled tires eliminate the possibility of air
leaks or blow outs which might cause a tipover.
Inspect them at the start of each work shift
according to the procedures in the “Daily
Inspection and Maintenance” chapter 7.
The foam filled tire shown here is not acceptable
for service.
❑ Large Tires
The large bar lug tires are designed for off
pavement use.
Their additional size provides a little more ground
clearance than regular bar lug tires and the bar
lugs give better traction off pavement.
■ Tow Kit
Improper towing can cause an AB50J to break
away from the towing vehicle.
A “runaway” AB50J can cause Death or
Serious Injury.
Do not tow an AB50J faster than 10 mph (16
km/h). An AB50J can behave erratically above
10 mph (16 km/ h).
When you tow the AB50J around a corner or a
curve do not turn so sharply that either of the
yokes are fully turned. If the yokes are fully
turned the steering mechanism might be
damaged or the tow vehicle and AB50J might
jackknife.
Check with the tow vehicle manufacturer or
manufacturer’s literature, to be sure the towing
vehicle can safely tow and stop a 15,280 pound
(6,930 kg) AB50J on the steepest grade and type
of surface you will encounter. Remember, the
AB50J does not have brakes when it is towed.
❑ Towing Procedures
1. Remove the tow bar and tie rod weldment
from the storage cradles and lay them near
the front of the chassis.
2. Attach the tow bar to the towing lug with the
tow pin and snap pin.
3. Attach the tie rod weldment to the tow bar
and the right hand steering yoke.
4. Attach the ring end of the tow bar to the tow
vehicle.
5. Raise the platform approximately 3 feet (1 m)
to keep the platform from scraping the
ground when the AB50J starts up a grade.
6. Pull the Steering Float Valve, located on the
front of the chassis, knob out and turn to lock.
Death or Serious Injury may occur from a
“runaway” AB50J.
7. Disconnecting the disconnect plates will
allow the AB50J drive wheels to turn freely.
Before proceeding, be certain the tow bar is
installed and connected to a towing vehicle
that can safely control both itself and the
AB50J.
