Feed the concrete mix shovel by shovel into the Hopper. Do not allow the mix to 7.
stack up in the Hopper. The Curb Machine will propel itself against the concrete
and will stop when the Hopper is empty.
The operator should be aware of the following:8.
That he steers the Curb Machine where it should be going. He can see the a.
inside of the Slip Form (1A, 1B, 1C) through the small window above the Motor
and Gear Box. Make sure not to get the machine hung up on roots or the sod.
(See Figure E.)
That he keeps the Curb Machine level by constant observation of the Leveler b.
(42). (See Figure E.)
That he keeps the Slip Form (1A, 1B, 1C) at the proper height. c.
(See Figure E.)
Feeding The Hopper:
It is not necessary or advisable to completely fill the Hopper with concrete. It is most 1.
efficient to tap the bottom of the Hopper with a shovel at the end of the Compac-
tion Ram (64) stroke to keep the Curb Machine moving. If the machine extrudes at
every stroke, it can produce over 500 feet per hour.
It is not recommended to use a small mouth shovel to stamp down the concrete, 2.
as it could become jammed by the Compaction Ram (64) resulting in damage to
the Gear Box or Drive Arm.
Hand Troweling:
The concrete finisher should be following the Curb Machine as soon as possible 1.
before the concrete begins to dry or set up.
All of the curbing should be hand troweled. Do not over trowel. But you should go 2.
over each section lightly at least once.
Some areas, especially tight curves and circles will leave cracks in the surface which 3.
can be filled and finished with a finishing hand trowel (not included). On tight circles,
a slightly wetter mix will help alleviate some of the cracking.
When finishing the work, keep firm but light pressure on the rear of the finishing 4.
hand trowel so that it does not gouge the concrete.
Installing Curbing In A Straight Line:
Mark the installation with a string line set 1/4 inch from the desired curb edge.1.
Run the Curb Machine with the left side (the “straight” side) along the string.2.
