21. REPAIRS
Repair, maintenance or lubrication operations must al-
ways be carried out with the machine stopped and the engine
switched off, except for the greasing indicated in par. 13.1
All maintenance operations, except for daily maintenance in any
case to be carried out by professionally qualified personnel, can
only performed by specialised personnel.
Use exclusively original IMER spare parts; modifications to
parts are strictly prohibited.
If any guards are removed for repairs, ensure they are
correctly refitted at the end of work and check the operation
of protection devices.
NOTE:
IMER INTERNATIONAL reserves the right to modify the charac-
teristics of the pump and/or the contents of this manual, without
having to update the previous manuals and/or machine.
22. 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 crystalline 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 respiratory disea-
ses, including silicosis. In addition, California and some other
authorities have listed respirable crystallinesilica as a sub-
stance 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 re-
spirator 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 California) 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 appro-
ved safety equipment, such as dust masks that are specially de-
signed to filter out microscopic particles. 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
