SAFETY
Your Diamond Products CC21 hydraulic hand saw has been designed to be as safe and
efficient as possible. However, hand sawing can be hazardous if proper safety
precautions are not taken and operating instructions are not followed carefully. Study
this manual and remember all warnings, cautions, and tips. Keep a copy of the manual
near the job site to allow the operator to review any section as needed.
SAFETY WARNINGS
PERSONAL SAFETY
•
Read and understand instructions before operating saw.
•
Wear proper safety clothing, including hardhat, respirator, gloves, and safety glasses.
Avoid loose fitting clothing.
•
Sturdy boots with non-skid soles aid in providing proper footing. Steel-toed safety
boots are recommended.
•
Cutting steel reinforcing bar produces sparks, avoid clothing of flammable material.
•
Know how to stop the saw quickly in an emergency.
•
Noise levels can be very high. Wear OSHA-approved hearing protection at all times
while the saw is operating.
•
Keep all parts of your body away from the blade and all other moving parts.
•
Do not operate the wall saw if you are under the influence of drugs or alcohol.
•
Do not use hands to search for hydraulic fluid leaks. Fluid escaping under pressure
can penetrate skin and cause severe injury. If any fluid is injected into the skin, seek
medical attention immediately.
•
Wear protective work gloves to avoid contact with concrete slurry that can cause
serious skin irritation.
BLADE SAFETY
•
Inspect the blade carefully before use. The blade should have no cracks, nicks, or
flaws. The arbor hole should be undamaged. Use only steel centered wet cutting
diamond blades manufactured for use on concrete hand saws.
•
Do
not
use dry cutting diamond blades, high-speed steel blades, carbide tipped
blades, or abrasive blades.
•
Only use blades marked with a maximum operating speed higher than the blade shaft
speed of 2500 rpm.
•
Ensure the hydraulic power pack is set at a flow rate of 17 gpm or below when using
the 1.58 cu in. displacement motor and at a flow rate of 14 gpm or below for the 1.28
cu in. displacement motor. (See Chapter 2; Technical Data)
•
Cut only stone, concrete, reinforced concrete, and masonry materials.
Do
not
cut
materials such as wood, glass, or plastic.
•
Inspect flanges for damage, excessive wear, and cleanliness before mounting the
blade. The blade should fit snugly on a clean, undamaged shaft.
