Recommended Operating Practices
This Section contains procedures that have been developed through
experience with asphalt distributors under a wide variety of working
conditions. Users of BearCat asphalt distributors will find these
procedures helpful and time saving. BearCat users who develop
techniques to improve the efficiency of the spreading operation are
encouraged to report these techniques. The information will be passed
along to other holders of this Operating Manual.
Using a Guide Chain
A chain can be hung from the guardrail that runs along the top of the
spray bar. It should be located at the outer limit of the spray pattern and
positioned so that the end of the chain just touches the ground when the
spray bar is at working height. The chain will be visible from the cab,
showing the exact location of the spray nozzles relative to the surface and
help to avoid overlaps and gaps.
Shooting a Straight Line
The following techniques will be helpful in controlling the vehicle so the
sprayed area follows a straight line with minimum need for weaving,
jogging, and random corrections.
When following an existing continuous line, such as a curb or guide string,
use the side shift as little as possible. Steering the vehicle to the guideline
will yield a smoother result.
When following a line of stakes or markers, DO NOT attempt to guide the
vehicle from stake to stake. You may create a scalloped effect. Instead,
choose a reference point (power pole, building, tree, etc.) in line with
your direction of travel and as far away as possible. Steer toward the
reference point. As the spray bar passes each stake, watch it in the mirror
and make minor corrections with the SWING switch.
Always make steering corrections as gradually as possible. Avoid sharp
jogs. They will be even more visible from ground level than they are from
the cab.
