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

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

•

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

•

materials such as wood, glass, or plastic.

use dry cutting diamond blades, high-speed steel blades, carbide tipped

cut

not

Inspect flanges for damage, excessive wear, and cleanliness before mounting the

•

blade. The blade should fit snugly on a clean, undamaged shaft.

Hydraulic power units are designed with the ability to vary the blade speed.

CUTTING/WORK AREA SAFETY

Never operate the saw in any application or job where you are not properly trained or

•

supervised.

Operate gas/diesel power packs only in well-ventilated areas.

•

Place barricades or tape to block off the work area. Keep bystanders, animals, and

•

unnecessary equipment out the work area.

Do not operate the saw near combustible material or fumes. Sparks occur during

•

sawing that may cause a fire or explosion.
