OPERATION

CUTTING TIPS

If using pipe clamp (Applicable for 4"-12", recommended for 8"-12").
• Place clamp around top of pipe, hand tighten adjustment nut.
• Position saw on pipe for top down or bottom up (recommended) cut and
slide saw clamp mount through receiver hole at top of clamp, secure with
snap pin.
• Slide clamp/saw assembly around pipe to optimum cutting position and
tighten clamp nut with wrench.
• Ensure saw is positioned to allow handle to pivot during cut unobstruct-
ed, and ensure saw tip doesn't contact dirt.
When the saw cut is complete be watchful of
sharp edges around the material that has been cut.
CUTTING FREE-HAND OR WITH PIPE CLAMP
When exiting the cut, avoid applying high feed
loads as unexpected movement of the saw may
result. Using both hands, maintain fi rm control
• Position saw to avoid pinching the bar or chain as pipe is cut, support
pipe from top and side to prevent cut pipe from injuring operator.
• Hold saw so chain isn't in contact with pipe, start water and activate saw
to recommended fl ow rate, press chain against pipe slowly, apply pres-
sure to cut through pipe.
• Pressure can be applied to cut until saw starts to lug, if need be back off
on the cutting pressure to maintain a good cutting speed.
• If cut in a 12" pipe exceeds 5 minutes, cut pulls to one side, or diamond
coating is gone, chain may need replacement.
