OPERATION
CUTTING WITH THE 633GC
To start a cut, hold trigger on full throttle and slowly plunge the nose of the bar straight into the wall.
Lengthen the cut and engage the point of the fixed Wallwalker®. Use the fixed Wallwalker® as a pivot
point and pull up on the rear handle to rotate the bar into the cut.
CUTTING TIPS
•
Always operate a diamond chainsaw 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 chain will not have
enough speed to cut effectively. If too little feed force is applied, the diamonds will skid and glaze
over.
•
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 fixed Wallwalker®.
•
For straight cuts use the “step cut” method. First score the entire cut line with the nose of the bar
approximately ½ inch (12mm) to 1 inch (25mm) deep. Next, deepen the cut by about 2 inches
(50 mm). This groove will help guide the bar for a straight cut. Then plunge all the way through and
complete the cut using the fixed Wallwalker®.
•
Use the fixed Wallwalker® to cut efficiently and reduce user fatigue. The fixed 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 point of the fixed 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 pick into the
cut and repeat.
•
When cutting heavy 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 chain life when cutting heavy
rebar.
•
Expect more chain stretch when making nose buried cuts for extended periods of time, as the chain
does not have a chance to “throw” the slurry away from the nose of the bar.
•
If the saw begins to cut consistently crooked, turn the bar over and use the other side. Dress worn
rails with belt grinder. Note: The normal life of a guide bar is 2 to 3 chains. Heavy rebar can shorten
bar life.
•
When using a new 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.
