7. Release the wheel brake. Turn depth adjustment
lever to free side while lifting the cut-off saw with
the cart-handle. Ground wheel to the floor and
gradually raise the engine speed. Use the cart
handle to adjust the load on the cutting edge so
a load is not put on it suddenly, and start cutting
little by little.
*At the beginning of cutting, the cart will try to
move forward, so hold the cart firmly while cut-
ting.

• Pay close attention while proceeding with a cut
to both the sound of the engine and the speed
of the cutting wheel to prevent overloading the
engine.
• If the cutting wheel slows down, relax the
forward pressure on the handle and back it off
slightly; wait for the engine RPM to recover and
then press down again.
• If the cutting wheel locks, release the throttle le -
ver and lift the cutting wheel up from the ground.
Grip the throttle lever again to raise the RPM
and start cutting. If the throttle is held in the fully
open position when the cutting wheel locks, it
may damage the engine cut-off saw.
• Pay particular attention when making maximum
depth cuts as the cutting wheel is then most
prone to locking. Not cutting any deeper than
necessary increases work efficiency and saves
on cutting wheels.
• Do not intentionally cut curves. Doing so puts
stress on the cutting wheel and makes it prone
to locking.
9. After finishing a cut, first lift the cutting wheel
and then release the throttle lever.
10. Shift the depth adjustment lever to the free side
and after putting the depth adjustment indicator
in the parking position, shift the depth adjust-
ment lever to the locked side to lock it.
11. Stop the engine and close the liquid cock to
stop it from flowing.
12. Always apply the wheel brake before leaving
the cart. If the cart is left on a slope, it may move
before it is noticed and cause an accident.

8. Cut down to the required depth and shift the
depth adjustment lever to the locked side.
Continuing the cut as-is will result in a cut at a
uniform depth. Refer to the index bolts when
determining the depth of the cut.
