OPERATION
Preparing for the Job
Find out what kind of concrete you will be pumping.
You should use a pipe and/or hose system that is three
to four times bigger than the largest rock in the mix.
You can use the chart in Figure 1 to select the correct
pipe diameter for the job.
Be sure that there is a water source on the job. You will
not be able to clean out without water.
Be sure that you have all items required for the pour.
You will need:
• a 5-gallon bucket
• a tool box with tools
• enough hoses, pipes and clamps to do the job
(Never join two different sizes of pipes or hoses
without a reducer. The longer the reducer, the less
pressure it will take to make the reduction. Never
join two different pipe styles (for example, a metric
coupling with a heavy-duty coupling). There is no
clamp made that will be able to keep the two sizes
together. If you have to change pipe styles, an
adapter pipe must be used. Any pipe or hose that
you use
must
be able to withstand the maximum
pressure of the concrete pump. The SP 305 can put
out significant pressure on the material. Use only
pipe and hoses that are in good shape. Do not use
pipe that has dents or thin spots. Do not use hose
that is frayed, has loose ends, or has loose rubber
on the inside.)
• a shovel
• any paperwork required for the job, such as
directions and contact person, fuel permit card, cab
card, insurance certificate
• any safety devices required for travel in your
location, such as flares, caution signs, first aid kit,
fire extinguisher
Be sure that lights and brakes on the towing vehicle
and on the trailer are in good working order before
leaving the yard.
Check all fluid levels on both the trailer and the towing
vehicle before leaving the yard (Figure 5).
Check the tires on both the trailer and the towing
vehicle before leaving the yard.
Don’t overload the trailer by using it as a cargo trailer.
The chassis was designed to carry only the weight of
the trailer. Don’t travel with concrete in the hopper.
Towing the unit
You will need more stopping distance when pulling a
trailer than when you are not. Do not tailgate.
Be extremely careful when backing up with a trailer. If
you are not experienced with trailer backing, you
should practice before getting on a public roadway.
