Grinding/cutting/drilling of masonry, concrete, metal and other materials can generate dust, mists and fumes containing
chemicals known to cause serious or fatal injury or illness, such as respiratory disease, cancer, birth defects or other
reproductive harm. If you are unfamiliar with the risks associated with the particular process and/or material being
cut or the composition of the tool being used, review the material safety data sheets and/or consult your employer,
the manufacturers/suppliers, governmental agencies such as OSHA and NIOSH and other sources on hazardous
materials. California and some other authorities, for instance, have published lists of substances known to cause
cancer, reproductive toxicity, or other harmful effects.
Control dust, mist and fumes at the source where possible. In this regard use good work practices and follow the recom-
mendations of the manufacturers/suppliers, OSHA/NIOSH, and occupational and trade associations. Water should
be used for dust suppression when wet grinding/cutting/drilling is feasible. When the hazards from inhalation of dust,
mists and fumes cannot be eliminated, the operator and any bystanders should always wear a respirator approved
by NIOSH/MSHA for the material being used.
Grinding/cutting/drilling of masonry, concrete and other materials with silica in their composition may give off dust or
mists containing 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 diseases, including silicosis. In addition, California and some other authorities have listed respirable
crystalline silica as a substance known to cause cancer. When grinding/cutting/drilling such materials, always follow
the respiratory precautions mentioned above.
SMI Dust and Silica Warning
EDCO Core Drill like any machine, with moving parts, as a preventative measure, should be cared for in the fol
lowing manner to insure its maximum working condition.
1. Motors - Supplied and warranted by motor manufacturer - listing of service centers nearest you will be supplied
with each motor or can be located in your local yellow pages.
2. Vacuum Pumps - Supplied and warranted by vacuum pump manufacturer. Listing of service centers located
nearest you supplied in the instruction packet.
3. Vacuum Base - Rubber gasket tends to be abused when moving the Core Drill. You should tilt the unit back far
enough, so that the wheels will touch the ground. The gasket should be checked periodically and replaced as
needed. Gasket material is made from a “closed cell” foam rubber stripping and can be purchased from your
local hardware store or ordered from EDCO. 3M brand super weather strip adhesive (3M part no. 051135-
08001) is used to attach the gasket ends together. Available at your local hardware store or can be ordered
from EDCO.
4. Column - Has a special lubricant to prevent rust. A light coat of oil is recommended to improve performance
and extend the life of the lubricant.
5. Carriage - (Refer to illustration on next page) - When carriage lock (#41) is loosened, the carriage should move
freely in an up and down mode only. Side to side play (Handle side to electric control box side) or back to front
play (Motor to operator) must be adjusted out periodically as wear dictates by adjusting the corresponding brass
wear strips (#50, 51). The brass wear strips (#48) (Motor side of carriage) and (Electric box side of carriage)
are fi xed and not adjustable. To adjust side to side clearance, locate item (#52) 1/4” Allen Head set screws
on the handle side of the carriage; using a 1/8” Allen Head Wrench adjust all 4 set screws evenly snug then
back off tension 1/8 to 1/4 turn, test and readjust if needed. To adjust back to front clearance, locate item (#52)
1/4” Allen Head set screws located top and bottom on either side of the column rack on the operator side of
the carriage. Using a left and right set screws evenly until snug then back off tension 1/8 to 1/4 turn, test and
readjust if needed. Other and may require varying degrees of adjustment according to use. Note: Adjustments
to the wear strips can be minimized through preventative maintenance. Regular cleaning followed by a light
application of oil or silicon spray on the entire column.
6. Ceiling Jack - Keep lightly oiled to prevent rust.
7. Electrical Control Box - After constant use, wires may loosen. (Do not work on the electrical box unless it is
unplugged from the power source.) Tighten or replace as needed.
8. General - Periodically check all bolts to insure tightness.
