6 Starting The Saw
(See Figures 1, 2 and 5)
Always pay extreme care and attention to the
preparation of the machine before starting.
Remove all wrenches and tools from the
oor and the machine.
Always keep blade guard, belt guards and
fan guards in place.
• Follow all operating instructions and warnings in this
manual and on the machine.
• Close the Water Valve (1T).
• Mark the surface to be cut by drawing a line where
the cut is to be made.
• Pull out Handle Bars (1B) to desired length and tighten
Knobs (1A).
• Lower the Front Guide (6D) and align the Front Guide
(6D), Rear Guide (6F) and Diamond Blade (2E) with
the line on the surface.
• To start the saw when no water pressure is present,
set the Water Safety Switch (1L) to “0” (OFF).
• Set Speed Control Lever (1O) to the STOP (1BB)
position. Saw will not start unless the Speed Control
Lever (1O) is in the STOP (1BB) position. Check to be
certain the Transmission Bypass Valve (5M) is closed
in the down position.
• Set the Blade Clutch Switch (1V) to “0” (OFF)
(if equipped).
• Start the engine using the Engine Start Switch (1H).
Follow the procedure in the engine manual.
In Cold conditions, pre-heat the engine glow plugs by
hold in the Engine Start Switch (1H) for 15 seconds.
• 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 Min.) Low water ow
will cause damage to diamond blades.
• Pull Throttle (1F) out to set engine RPM at 3000.
See chart for the appropriate blade shaft and
engine speeds for specic blade sizes.
• Move the saw forward or reverse 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.
• Set the Blade Clutch Switch (1V) to “1” (ON) to
engage the Blade Drive (if equipped) ONLY AT IDLE
SPEED OF ENGINE!
• Lower the saw by pressing the Raise/Lower 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 ow 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 pre-set using the BLADE DEPTH INDICATOR
(1Q). It can be used with or without the BLADE DEPTH
STOP SWITCH (1M) feature. As the saw is lowered,
the BLADE DEPTH INDICATOR (1Q) needle travels
through the White color number range in decreasing
order, indicating the unnished depth of cut. When
the BLADE DEPTH INDICATOR (1Q) needle reaches
“0” position, the desired maximum cutting depth is
reached. If the BLADE DEPTH STOP SWITCH (1M)
feature is used (“1” or “ON” position), the lowering
process stops automatically.
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.
To Remove A SLIP-ON GUARD:
• Using the Blade Shaft Wrench remove the rear
retaining bolt.
• Slip the Blade Shaft Wrench between the guard and
the belt guard onto the latch lever. Raise the lever to
unlatch and lift guard off spade.
To Install A SLIP-ON GUARD:
• Lower guard onto spade until latch engages.
• Install Bolt in rear of guard using the Blade Shaft
Wrench.
