DALTOOL®SAFETY
The use of saws and drills generates dust. Excessive airborne particles may cause irritation to
eyes, skin and the respiratory tract. To avoid breathing impairment, always us dust controls and
protection suitable to the material being sawed or drilled;
See OSHA (19 CFR Part 1910.1200). Diamond Blades improperly used are dangerous. Comply
with American National Standards Institute Safety Code, B7.1 and, Occupational Safety and
Health Act covering speed, Safety Guards, Flanges, Mounting Procedures, General Operating
Rules, Handling, Storage and General Machine Conditions.
CALIFORNIA PROPOSITION 65 MESSAGE:
Some dust created by power sanding, sawing, grinding and other construction activities contain
chemicals known [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
For Further information, consult the following sources:
http://www.osha-slc.gov/sltc/sillicarystalline/index.html
http://www.oehha.org/prop65/out_of_date/6022kLstA.html
Your risk from these exposures varies depending on how often you do this type 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 designed to filter out microscopic
particles.
TILE DRILL SPECIFIC WARNINGS:
● Do not touch the diamond bit during operation.
● Do not leave the machine turned “ON” when not in use.

OPERATING PROCEDURES
Ventilation openings in the
housing of the machine
● The ventilation openings must be free
from objects such as Styrofoam, stone or
concrete debris. Remove these objects
before using the machine. If the ventila-
tion openings are not clear it will
mean that the cooling of the motor is
diminished and can damage the
machine.
● There is a small hole in the water
injection head located behind the
connecting valve for the water hose.
When water comes out this small hole it
is recommended that you stop using the
machine and to contact your local
service center. Continuing to use the
machine can result in damage to your
machine
Storage after Use
