OPERATIONS
WARNING:
Never start a diamond chain saw without the bar,
chain and side cover properly assembled. Failure to do so may
result in serious injury.
CAUTION:
Always check hose connections before turning on air
compressor.
CAUTION:
Hold saw with both hands and ensure the chain is
not contacting any objects.
WARNING:
Before cutting, make sure the pipe is in a safe condi-
tion to be cut. Support the piece you are going to be cutting
in such a way that the cut will remain open during the cut and
when the cut is finished. Pinching the chain during the cut could
cause chain breakage and could result in death or serious
injury to the operator.
If using the pipe clamp accessory, the clamp must be attached
in such a way that it does not move during the cutting operation
and/or when the cut is finished. Unexpected movement of the
clamp could cause the operator to lose control of the saw result-
ing in death or serious injury.
With the saw engaged in any surface the operator should be
aware that the forces generated by the tool can force debris to
be ejected from the moving chain either away from the saw or
towards the operator. Ensure no bystander is located immedi-
ately in front of or behind the material being cut.
CAUTION:
The single most important factor an operator can
control to increase chain life is to use adequate water pressure.
Insufficient water supply will result in excessive wear to the
chain which can lead to loss of strength and chain breakage
and/or damage to the guide bar nose sprocket.
6.0.1
Ensure Proper Chain Installation: Concrete chains should
lead with the bumper segment into the cut. Ductile chains can be
mounted in either direction.
6.0.2
Ensure Proper Chain Tension: The chain should be tight
but easily pulled around the bar by hand.
6.0.3
Ensure all safety devices are properly mounted and func-
tional. Ensure all controls are in working order.
6.0.4
Be sure there are no obstructions (plumbing, electrical
conduit, air ducts, etc.) and no unnecessary people present.
6.0.5
Always wear protective clothing, including hard hat, eye
protection, hearing protection, non-slip safety boots, and gloves.
Avoid wearing loose fitting clothing.
6.0.6
Use Adequate Water Supply and Pressure:
Minimum Flow: 1gpm
Recommended Water Pressure: 20psi
6.0.7
Use Proper Air Supply:
Minimum PSI : 90
Minimum CFM: 90
6.0.8
Blow the air supply line clear before connecting to the
saw.
6.0.9
Check oil level; if necessary, re-fill oiler with ice-free air
tool oil.
6.0.10
The chain should travel away from the operator on the top
side of the bar during operation.
6.1.1
Select the proper chain type for the material being cut.
6.1.2
Outline the cut with a permanent marker for a visual cut-
ting edge.
6.1.3
Avoid pinching the guide bar and chain. Always cut the
bottom of an opening first, then top, and then the sides. Save the
easiest cut for last.
6.1.4
For the straightest cuts in concrete use the “Step Cut”
method. First, score the entire cut line approximately a half-inch
deep using the nose of the bar. Next, deepen the cut by about two
inches. Then, plunge all the way through and complete the cut.
6.1.5
For the straightest cuts in pipe cutting applications cut
from the bottom up using the Pipe Clamp.
6.1.6
Be sure that cut material cannot fall and injure operator or
bystanders.
6.1.7
Check for live electrical wiring near the cut or in the con-
crete to avoid electrocution.
6.1.8
Check for and remove all obstructions (plumbing, electri-
cal conduit, air ducts, etc.) that may interfere with the cut.
6.2.1
All concrete pipe cutting chain saws are considered
specialty tools. The overall cutting speed is slower that some other
types of cutting equipment. For this reason the correct time alloca-
tion should be made so that the operator has time to make the cut
at a safe pace and not have to force the saw to try and increase pro-
duction. Forcing the saw creates unneeded wear on chains, bars,
and drive components. Additionally, long periods of exertion can
cause operator fatigue which can increase the likelihood of injury.
