Factors Affecting Chain Life:
All of the following factors can negatively affect chain life:
|
• |
Steel Reinforcing...many
pieces or large diameter rebar causes reduced life. |
|
• |
Aggregate Hardness...harder
aggregates cause reduced life. |
|
• |
Operator Experience...first
time users generally get less chain life. |
Cutting Tips to Improve Chain
life:
|
• |
Use minimum 20 psi water
pressure. |
|
• |
Always cut at full throttle.
Slowly plunge straight into wall. Push hard enough to cause
the RPM's to drop by 25-30%. Always apply STEADY feed force. |
|
• |
SLOWLY rock the bar and chain
in the cut using Wallwalker® as pry point. |
|
• |
Reduce arm motions. Hold saw
close to body and use legs and body to apply feed force.
Always cut between shoulders and knees, preferably at waist
high. |
|
• |
If the saw begins to drift
off the intended cut line, pull out and restart the cut. |

Inch-Foot Definition
|
• |
An in-ft is how
professional concrete cutters measure chain or blade
life. |
|
• |
An in-ft is defined as:
DEPTH of cut in inches times LENGTH of cut in feet. |
|
• |
1 sq-ft = 12 in-ft = 144
sq-in |
|
• |
1 sq-m = 129 in-ft |
Example: Determine how many in-ft are in this doorway:
-
Determine the depth of the
cut in inches.
For this example, 8 inches.
-
Determine the length of the
cut in feet.
3 + 7 + 3 + 7 = 20 feet
-
Multiply the two numbers.
8 in x 20 ft = 160 in-ft
