OPERATION
CUTTING TIPS
• To start a cut, hold trigger on full throttle and slowly plunge the nose of the guide bar straight into
the wall. Use the fixed Wallwalker
®
as a pivot point and pull up on the rear handle to rotate the
guide bar into the cut.
• Always operate the saw at full throttle. Apply enough feed force so that the free running RPM
drops 20 to 30%. If too much force is applied, the saw will lug or stall. The diamond chain will not
have enough speed to cut effectively. If too little feed force is applied, the diamonds will skid and
glaze over.
• For straighter cuts use the “step cut” method. First score the entire cut line with the nose of the
guide bar approximately 1/2 inch (12mm) to 1 inch (25mm) deep. Next, deepen the cut by about
2 inches (50 mm). This groove will help guide the guide bar for a straight cut. Then plunge all the
way through and complete the cut using the Wallwalker
®
.
• Plunge cut instead of starting at the top of the wall. This will reduce chatter, extend diamond life,
create a straighter cut and more quickly enable the use of the Wallwalker
®
.
• Use the Wallwalker
®
to help cut more efficiently and reduce operator fatigue. The Wallwalker
®
is a
fulcrum that can be used to apply additional force when cutting. To use correctly, plunge into the
wall and simply engage the bumper of the Wallwalker
®
into the cut and pry upward with the rear
handle.
• As the saw begins to rotate up, feed force is developed down the line of the intended cut. Once
the saw is fully rotated upwards, pull the saw out of the cut a few inches and re-engage the
Wallwalker
®
to the wall and repeat.
• When cutting rebar, slowly ”rock” the saw so that you’re always cutting concrete as well as steel.
This will help keep the diamonds exposed. Also, expect less diamond chain life when cutting
rebar.
• Expect more diamond chain stretch and guide bar wear when making “nose buried” cuts for
extended periods of time, as the diamond chain does not have a chance to “throw” the slurry
away from the nose of the guide bar.
• If the saw begins to cut consistently crooked, turn the guide bar over and use the other side.
Dress worn rails with belt sander. Note: The normal life of a guide bar is 2 to 3 diamond chains.
Rebar can shorten guide bar life.
• When using a new diamond chain, you can increase the cutting speed by “opening up the
diamonds”. Make a few cuts in an abrasive material such as a cinder block.
