SAFETY DECALS
SAFETY DECALS ARE PROVIDED WITH YOUR HEIL DRY BULK MATERIALS TRANSPORT . PLEASE CAREFULLY READ THE MESSAGES CONTAINED WITHIN THE DECALS AND BE ALERT TO THE POSSIBLILITY
OF PERSONAL INJURY OR DEATH.

WARNING
Do not exceed working pressure. If pressure rises
above limits, shut down immediately and investigate.
WARNING
NEVER open manhole unless
tank is completely depressurized. Even a slight amount of residual pressure will cause manhole to fly open when unlatched.
WARNING
The Relief Valve must be operational to
maintain system pressure within safe
limits. Failure to properly maintain the
relief valve may cause property damage,
potential injuries and death.

WARNING
When unloading, the discharge
hose must be secured at both
ends prior to pressurizing unit.
Always relieve pressure in discharge hose before disconnecting it.

16

NOTICE
Blowdown valve should be OPEN at all
times except when unloading. This
will help relieve pressure buildup due
to changes in ambient temperature,
friction, product expansion, etc.
WARNING
To avoid suffocation, never enter a tank containing pulverants,
liquids, flammable or caustic
materials. Always follow all confined space entry procedures.
CAUTION
To avoid product contamination or mixing of incompatible materials, clean tank thoroughly before switching payloads.
CAUTION
To prevent a vacuum from developing when unloading without
pressure, open manhole before opening discharge valve.
WARNING
Never operate this
bulk transport unless you are fully
aware of the location of all the control valves and shut
down procedure.

17

CAUTION
Vehicle safety checks should be performed daily prior to
operation.

CAUTION

CAUTION

If a leak is discovered during
operation, shut down immediately and repair the leak.

To avoid spillage, product discharge valves must be closed
prior to loading and while in
transit.

Notice
All check valves must be operational to prevent product
back-up into the supply
lines.
WARNING
Maintain non-skid surface at top of tank
free of ice, snow, sleet, rain, oil, grease,
etc. prior to climbing on top.

WARNING
Decals are posted on the tank to alert the operator of potential
dangers. Replace decals when illegible.

PIPING SYSTEM COMPONENT DESCRIPTIONS
1. AIR SUPPLY BLOWER — On-board supply of air for unloading trailer.

2. MAIN AIR SUPPLY LINE CHECK VALVE-permits one-direction flow from
power source to tank and prevents air-borne product from backing up to
power source when pressure in tank is greater than in supply lines.

3. MAIN AIR SUPPLY LINE-transfers air from tractor air supply line to aeration and discharge lines.

22

PIPING SYSTEM COMPONENT DESCRIPTIONS
4. PRESSURE RELIEF VALVE - Prevents pressure inside vessel from exceeding maximum operating pressure.

FOLDING HANDRAIL DESCRIPTION AND OPERATION

This Heil Super Jet trailer is equipped with a mechanical folding handrail system intended as a secondary fall protection device. When used in conjunction
with other facility safety equipment, it helps to protect an operator working on
top of the trailer. The folding handrail system consists of the following:
1. Vertical aluminum stanchions and horizontal aluminum rails
2. Pneumatic cylinders, one located on each side, for each handrail.
3. Safety switches and locking pins, one located on each side, for each handrail.
a. Engage safety switches (one each side) while working on top of trailer to prevent inadvertent ground operation.

b. Insert mechanical locking pins (one each side)
through valve bracket and locking tab on stanchion
to keep handrails from folding down in the event
that air cylinder pressure bleeds off. DO NOT insert
locking pins unless air safety switches are flipped
forward.
