•Start the engine using the ENGINE START SWITCH (1H). Follow the procedure in the engine manual. In Cold conditions,
•Let the engine warm up for several minutes with ENGINE THROTTLE (1F) at the low speed setting.
•When ready, open the WATER VALVE (1T).
•Set WATER SAFETY SWITCH (1L) to “1” (ON).
Test for adequate water supply. (2.5 - 5.0 GPM) (10 - 20 Liters per Minute) Low water flow will cause damage to diamond blades.
•For Machines without the Optional BLADE CLUTCH SWITCH (1V): Pull ENGINE THROTTLE (1F) out to set engine RPM at 3200, as shown on the ENGINE TACHOMETER (1G).
See chart for the appropriate blade shaft and engine speeds for specifc blade sizes.
•Move the saw forward or reverse (Standard and Front Pivot Models) slowly by pushing or pulling on the Speed Control Lever (1O). Move the saw slowly to prevent stalling the blade. Make sure the Front Guide (6D), Rear Guide (6F) and DIAMOND BLADE (2E) stay on the line.
Rear Pivot Model Only: For the Rear Pivot Model, aligning to the cutting line can be made using the pivot feature on the machine. Simply move the DIFFERENTIAL SWITCH (1J) to the Left position (Pivot), and then use both hands to push down on the HANDLEBARS (6G), and the machine can be pivoted from side to side to align with the cutting line. After the saw is properly aligned to the cutting line, toggle the DIFFERENTIAL SWITCH (1J) to the Center (Lock) position.
•Set the BLADE CLUTCH SWITCH (1V) (if equipped) to “1” (ON) to engage the Blade Drive when engine is at IDLE SPEED (1200 RPM or less)! When clutch engages and blade is at idle speed, pull out ENGINE THROTTLE (1F) and set engine RPM at 3200.
•Lower the saw by pressing the TOGGLE SWITCH (1P) on the SPEED CONTROL LEVER (1O) downward until the DIAMOND BLADE (2E) is at the desired cutting depth (See “Blade Cutting Depth Information”).
Be certain that water flow is abundant for wet sawing.
Blade Cutting Depth Information:
The saw is equipped with a BLADE DEPTH INDICATOR (1Q) which has two number ranges. The Orange and White number ranges are used for two different purposes:
1)The “Depth” number range, indicated by the Orange color, shows the current Cutting Depth of the DIAMOND BLADE (2E). As the saw is lowered, the BLADE DEPTH INDICATOR (1Q) needle travels through these numbers in increasing order. Or
2)The “SMD” or “Set Maximum Depth” number range, indicated by the White color, is the uncut depth of the DIAMOND BLADE (2E). The desired maximum cutting depth is
Using the BLADE DEPTH INDICATOR (1Q):
“Depth” Mode (Orange colored numbers show current cutting 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.
•Turn BLADE DEPTH STOP SWITCH (1M) to “0” (OFF) position.
•Lower DIAMOND BLADE (2E) by pushing the TOGGLE SWITCH (1P) on the SPEED CONTROL LEVER (1O) downward until the DIAMOND BLADE (2E) touches the surface to be cut.
•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.
