The saw WILL NOT lower to any depth
greater than the position set on the BLADE
DEPTH STOP SWITCH (1Q). If a deeper cut is
required, the BLADE DEPTH INDICATOR (1Q)
MUST be turned to the new depth position.
Or push the BLADE DEPTH STOP SWITCH
(1M) to “0” (OFF) position to override the
Depth Stop Feature.
• Rotate the BLADE DEPTH INDICATOR (1Q) needle to
align to the “0” depth.
• As DIAMOND BLADE (2E) is lowered into the cutting
surface, the current cutting depth will now be indicated
by the Orange text number range on BLADE DEPTH
INDICATOR (1Q) needle.
SMD or “Set Maximum Depth” Mode without
BLADE DEPTH STOP (White colored numbers show
uncut depth):
• Turn ENGINE START SWITCH (1H) to “0” (OFF)
position to STOP engine (If running).
• Turn ENGINE START SWITCH (1H) to “1” (RUN)
position to power electrical system.
• Lower DIAMOND BLADE (2E) by pushing TOGGLE
SWITCH (1P) on the SPEED CONTROL LEVER (1O)
downward until DIAMOND BLADE (2E) touches the
surface to be cut.
• Rotate the BLADE DEPTH INDICATOR (1Q) needle to
align with the desired maximum cutting depth on White
colored number range. The uncut depth will now be
indicated on the White colored number range. When
the BLADE DEPTH INDICATOR (1Q) needle gets to the
“0” position, the saw is cutting at the desired maximum
cutting depth.
• Raise the blade by pushing the TOGGLE SWITCH (1P)
on the SPEED CONTROL LEVER (1O) upward until the
DIAMOND BLADE (2E) is off of the cutting surface.
• Turn the ENGINE START SWITCH (1H) to the “0” (OFF)
position to turn off power to electrical system.
SMD or “Set Maximum Depth” Mode using BLADE
DEPTH STOP SWITCH (1M) (White colored numbers
show uncut depth):
• Turn ENGINE START SWITCH (1H) to “0” (OFF)
position to STOP engine (If running).
• Set the BLADE DEPTH STOP SWITCH (1M) to
the “0” (OFF) position to override the depth stop
setting. Saw will raise and lower over its full range
without stopping.
• Turn ENGINE START SWITCH (1H) to “1” (RUN)
position to power electrical system.
• Lower DIAMOND BLADE (2E) by pushing TOGGLE
SWITCH (1P) on the SPEED CONTROL LEVER (1O)
downward until DIAMOND BLADE (2E) touches the
surface to be cut.
• Rotate the BLADE DEPTH INDICATOR (1Q) needle to
align with the desired maximum cutting depth on White
colored number range.
• Set the BLADE DEPTH STOP SWITCH (1M) to “1”
(ON) position.
• Raise the blade by pushing the TOGGLE SWITCH (1P)
on the SPEED CONTROL LEVER (1O) upward until the
DIAMOND BLADE (2E) is off of the cutting surface.
• Turn the ENGINE START SWITCH (1H) to the “0” (OFF)
position to turn off power to electrical system.
• Now the maximum cutting depth is set. If the saw is
raised out of the cut surface for any reason it can now
be lowered to “Set Max. Depth” by lowering the blade
until the saw lowering movement stops.
7 Stopping The Saw
(See Figures 1-2)
For EMERGENCY STOP, press down the
RED PALM SWITCH (1K) on the cowl. This
will stop the engine and disconnect power
to all electrical items except lights. Reset the

• Lack of water signals the Water Safety Switch (1L)
to stop the engine. Set Switch (1L) to “0” (OFF) and
then restart the engine.
• Excessively fast cutting speed will stall engine.
• Red Palm Emergency Switch (1K) has been pressed
down. Reset by pulling toggle switch until it pops
upward.
• Circuit Breaker is blown (1Z). Push to Reset
If the Diamond Blade (2E) STOPS during sawing,
check:
• Drive belt tension is inadequate.
• The clutch switch has been pushed to “0” OFF
• The clutch has an electrical failure or blown fuse.
