Cutting tips to improve chain life
Use a minimum of 20 PSI water pressure
Always cut at full throttle, slowly plunge into the wall, and push hard enough to cause the RPMs to drop by 25% to 30%
Always apply a steady feed force
Slowly rock the bar and chain into the cut using Wallwalker as a pry point
Reduce arm motions and hold the saw close to the body, using legs and body to apply feed force; always cut with the saw between shoulders and knees, preferably at waist height
If the saw begins to drift off the intended cut line, pull out and restart the cut
