Maintenance; Silica Dust Warning - IMER KOINE 35 Manual

Stop the machine by means turing the selector (Ref.Q5) to "0",
Proceed with pipeline cleaning. Insert a washing sponge (ref.16)
at the start of the pipeline, connect the material delivery hose to
the mortar hose-water hose coupling (ref.17), and then connect
the latter to the auxiliary water valve. Insert the water pump and
open the auxiliary water valve until the washing sponge comes
If using pipelines with a different diameter for cleaning, use a
suitably sized sponge. Repeat the operation until the pipeline is
perfectly clean.
At this point, on completion of machine cleaning, turn off the
main switch, disconnect the power plug, close the water delivery
valve, open the auxiliary valve for a few seconds and detach the
delivery hose.
If there is any risk of freezing, open the three valves (ref.18) as
Remember to reclose the valves before restarting the machine.
If the machine is not to be used for several days, empty the hopper
completely, opening also the drain plug (ref.5, see EXPLODED
MACHINE DRAWING).
Also remove the cell wheel.
- Before opening the drain plug or the grille, ensure that
the main switch is turned to 0 and the plug is disconnected
from the power supply

16. SILICA DUST WARNING

Grinding/cutting/drilling of masonry, concrete, metal and other materials
with silica in their composition my give off dut or mists cintainig crystalli-
ne silica. Silica is a basic component of sand, quartz, brick clay, granite
and numerous other minerals and rocks. Repeated and/or substantial
inhalation of airborne crystalline silica can cause serious or fatal respira-
tory diseases, including silicosis. In addition, California and some other
authorities have listed respirable crystallinesilica as a substance known
to cause cancer. Whwn cutting such materials, always follow respiratory
precautions.
Use appropriate NIOSH-approved respiratory protection where dust
hazard may occur. Paper masks or surgical masks without a NIOSH
approval number are not recommended because they do little to protect
the worker. For more information about respirator programs, including
what respirators have received NIOSH approval as safe and effective,
please visit the NIOSH website at:
http://www.cdc.gov/niosh/topics/respirators
Observe OSHA regulations for respirator use (29 C:F.R. § 1910.134).

California proposition 65 message
Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities contain chemicals know (to the State of Ca-
lifornia) to cause cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
-Lead, from lead-based paints
-Crystalline silica, from bricks and cement and other masonry products
-Arsenic and chromium, from chemically treated lumber

Your risk from these exposures varies depending on how often you do
this typer of work. To reduce your exposure to these chemicals, work in
a well-ventilated area, and work with approved safety equipment, such
ticles. Where use of a dust extraction device is possible, it should be
used. To achieve a high level oof dust collection, use an industrial HEPA
vacuum cleaner. Observe OSHA 29 CFR part 1926.57 and 1926.103
