SECTION VI
MACHINERY OPERATION
Before reading the machinery operation section, new operators should familiarize themselves
with the all diagram views of machine. These drawings show the activation of all moving parts
of the TWISTER.
Even though the TWISTER surface prep machine is very easy to drive and operate, it is
recommended that all operators familiarize themselves with this equipment before attempting to
use machine in a jobsite or removal situation. This machine has certain steering characteristics
that should be noted and practiced prior to operating in a confined space or restrictive
environment.
1.
TO MOVE THE MACHINE:
Using the right hand, slowly move the shifter lever
in the desired direction of travel. Forward and left moves the machine to the left,
backward and right reverses the machine to the right. It is just that simple to drive. Speed
is controlled by amount of movement on the joy stick and or engine RPM. The higher the
RPM’S the faster the machine will travel.
2.
TO ENGAGE BLADE TO SURFACE:
Move left joystick lever forward
to lower blade bar assembly down. Move lever back to raise blade bar assembly off floor.
Left and right movement adjusts the blade pitch.
3. Throttle control is on the left side of the seat, taking the unit from idle to 3200
RPM. The most optimum speed is 2600 to 3000 RPM. To change RPM of engine move
throttle lever forward to increase engine RPM and backward to decrease engine RPM.
4.
To change scraping blades: Lift blade to full UP position. Place a block under blade bar
assembly for safety purposes. Stop engine. Loosen the set bolt at the rear of the Blade
holder block using a ¾” open
-end wrench. Slide the dull blade out and Insert a new
blade up against the shoulder stop. Retighten the set bolt and resume scraping.
The large 1 1’8” blade holder bolt should not need to be more that hand tight.
With a little practice you should be able to change blades in 15 seconds. Dull
blades can be resharpened and reused many times.
SEE DRAWING OF BLADE CHANGE PROCEDURE
5.
Operators should lower the blade by pressing the left hand lever forward each
time they get off the machine. This safety practice eliminates possible bodily
injury from lowering the blade by unauthorized operators.
6.
The transport caster should not be in contact with the floor while scraping. It will
lift off the floor when blade is lowered. Caster contact with the floor while
scraping will negatively affect scraper productivity and steering.
7.
Do not transport machine with front of machine off the surface of floor higher than 1/2".
