The EASy system monitors the position of the placing
boom and outriggers. If the machine senses a problem
it will display a warning message on the Vector panel
and sound the horn. It is important to follow the instruc-
tions on the screen. Most warning messages can be ac-
knowledged with the QUIT and CLEAR buttons. Once
a message is acknowledged, operation of the placing
boom can be continued. Reference your operation
manual for a complete list of fault messages.

while using the EASy system.
Safety Shutdown Fault
If you receive a serious fault that e󰀨ects the safe opera-
tion of the machine, the placing boom will stop, remote
box will be disabled and the horn will sound. The mes-
sage !Safety Shutdown! is displayed and the machine
is placed in E-Stop mode. Clear the E-stop and imme-
diately fold up the placing boom in accordance to the
Emergency Operation procedure in your operational
manual.

EASy Setup - Outrigger moves
When setting up the machine, en-
sure that after the front outriggers are
extended, you secure them with the
outrigger lock.
While pumping concrete, it is possible for the outriggers
to move slightly and trip the stabilization sensor. When
this happens you will receive the following message on
the Vector panel, "Check outriggers !."To remedy this
fault, you can either reposition the outrigger or bypass
the outrigger sensor.
Check outriggers !

Reposition outrigger
Put the concrete pump in the neutral position. Place the
local/remote switch in the local position. Ensure that all
personal are clear of the machine. Press the outrigger
button while activating the outrigger handle. Extend

the outrigger into proper setup position. The warning
message will go away and you can resume pumping
concrete.
Bypass Outrigger Sensors
If you don't want to reposition the outrigger, press the
CLEAR button as instructed on the screen. The warning
message will go away and the outrigger sensors will be
bypassed - meaning the machine will no longer monitor
the position of the outriggers. The placing boom will still
be limited to the selected working range.
If you bypass the outrigger sensors, you are responsi-
ble for maintaining the setup of your machine, ensure
the outriggers are not moved until the after boom is fold-
ed up and placed in the cradle.
If you try and move the boom with the "Check outrig-
gers !" warning message displayed, you will receive an-
other fault message "! Machine Safety Stop! Machine
not correctly stabilized!" A horn will sound and the
boom will stop moving. To continue moving the boom
press the QUIT button once. The warning horn will shut-
o󰀨, but the message will still appear. Press the QUIT
button again to clear the fault message. The boom can
now be operated normally.

Temporary Truck Shutdown.
At times you may want to setup the machine and then
shut the truck o󰀨 while you wait for concrete.
With the machine properly setup, shut the truck engine
o󰀨. When you are ready to resume, turn the truck engine
back on. The Vector control panel will power up. You will
receive the following warning "! Machine Safety Stop!
Boom is Not in Cradle!" Press the QUIT button once
to silence the horn, press the QUIT button again to clear
the fault message.

The next message to appear is "Is the unit supported
by all outriggers?" Since we have already properly set
up the machine, all we have to do is the press the out-
rigger buttons on both sides of the unit for 5 seconds
- or until you hear the horn beep. The machine is now
ready to operate.

Setup Tip
Extending Outriggers - EASy 180/200
We recommend when setting up in EASy 180/200
mode, to extend the outriggers and lower the feet on
the working side rst. When the working side outriggers
are fully extended, secure the front outrigger with the
outrigger lock.

Fully extend outriggers on the working side
Extend the front outrigger on the non-working side until
you hear the horn beep twice. Lower the outrigger feet
and level to within 3 degrees.

Extend the outriggers as much as
possible on the non-working side,
even if it's a couple of feet, it will add
to the stability of the machine.

Unfolding the Boom
Before unfolding boom section 4 (joint D), boom section
5 (joint E) must be opened at least 40°, to avoid a col-
lision between boom sections 3 and 5. Please refer to
"Boom unfolding procedure" on page 5 to properly
unfold the boom.
Observe the placing boom constantly
and avoid contact with obstructions.

If joint "D" has an opening angle of > 150°or boom sec-
tion 3 is in full contact with section 4, joint "E" can be
folded together at an angle of less than 40°.

Calculating the Outrigger Load
After you nd an appropriate spot to set up the unit, you
must provide a stable base for the outriggers. If the site
you have chosen does not have stable soil conditions,
select a di󰀨erent site. Under no circumstances should
you compromise the stability of the unit by setting up on
unstable soil.
The following chart can be used as a guideline to help
you determine the load-bearing capacity of various soil
types. If you do not know what type of soil is on your job
site, the site manager may be able to tell you.
Soil Type PSI
Virgin ground 22
Asphalt 29
Compressed, crushed stone 36
Clay/silt soil, rm 43
Mixed granular soil 51
Firm, compacted gravel 58
Firm, compacted gravel (more compacted) 72
Firm, compacted gravel (more compacted,
class V)
109
Brittle, weathered rock 145
To determine the load your outriggers will impose on
the soil, divide the total force of the outrigger (shown on
a decal on the outrigger leg) by the number of square
inches of soil contact:
Soil pressure (PSI) = total outrigger force (lbs) ÷ area
of soil contact (sq. in.)
total outrigger force (lbs) =Soil pressure (PSI)
area of soil contact (sq. in.)
98419619
43,800 LBS

MAX. OUTRIGGER LOAD

Outrigger Calculations
The front outrigger decal on the S38SX shows a max-
imum force of 43,800 lbs. The steel outrigger pads are
9.4 inches in diameter (70 sq in.). Dividing 43,800 by 70
gives a soil pressure of 626 PSI:
43,800 (lbs) =626 (PSI)
70 (sq. in.)
As you can see from the Soil Type chart, the steel
pads are not big enough to be used by themselves on
any of the soil types listed. This is why the unit comes
equipped with dunnage pads The pads are approxi-
mately 24” by 24” (576 sq in.). Now divide the maximum
force of 43,800 by 576:
43,800 (lbs) =76 (PSI)
576 (sq. in.)
The pressure of 76 PSI is suitable for rm, compacted
gravel (more compacted, class V). If you had to set up
on virgin ground, asphalt, or one of the other soil types
listed, you would need to use additional cribbing.

How to calculate cribbing needs
Cribbing requirements for setting up on Asphalt with a
43,800 pound outrigger load.
We have already calculated the pressure being exerted
by the dunnage pad alone is 76 PSI (dividing 43,800 by
576 the size of the dunnage pad in square inches.)
76 PSI exceeds the capacity of the asphalt, which is 29
PSI, the outrigger would sink.
Cribbing must be used to increase the surface area
over which the force is applied. To determine the di-
mensions “A” of the cribbing required, divide the Total
Force (43,800) by the soil capacity (29).
43,800 (lbs) =1510 (sq. in.)
29 (PSI)
The result (1510) is the surface area, expressed in
square inches, required to support the outrigger. Con-
sult the table below and select a cribbing size slightly
larger than required. In this example, we recommend a
Cribbing size of 40” X 40” (1600 sq. in.).
Square inch surface required Dimension “A”
400 20 x 20
625 25 x 25
900 30 x 30
1225 35 x 35
1600 40 x 40
2025 45 x 45
2500 50 x 50
You can also take the square root of 1510, which is
38.8. Rounding up to 40, we would need 40” x 40” of
cribbing to support the weight of the outrigger. If we use
10 pieces of 4 x 4 timbers (actual width of 3.5” square)
measuring 40” long we get the following:
4” square timber X 10 pieces = 40 sq. in.
40 sq. in. X 40” long timbers = 1600 sq. in.
1600 sq. in. would be just enough cribbing to support
the outrigger on asphalt.
The same procedure can be used for any soil surface,
just be sure to use the correct soil capacity pressure
capacity.
