TACHOMETER/ HOURMETER
A self-powered digital Tachometer/Hourmeter keeps true
running RPM and time. The operation is triggered by an external
lead wrapped around the spark plug of the engine. When the
engine is running, the display will read the RPM of the engine.
When the engine is off, the display will switch to run time (initially
in minutes), and then switching to hours after the first hour of
operation. This instrument provides quartz crystal solid-state
technology, and is built with a custom chip and die bonding
construction for maximum durability.
Figure 6 shows the location of the components of the FS2
Console. The function of each component is described below:
1. Horizontal Depth Feed Gauge – Indicates the blade
cutting depth in inches. The scale allows for orientation of
12, 14, 16 and 18 inch diamond blades.
Depending on the blade diameter selected, the steel
pointer head will indicate zero inches when the blade is
just touching the surface, positive numbers when below
the surface, and negative numbers when above the surface.
The "Depth Feed Gauge" is calibrated in inches and is set
at the factory
2. 3-Way Water Valve – 3 position selector valve, OFF, Mist
or Flood.
3. Raise Lower Crank Handle – Raises or lowers the cutting
blade. This handle is used in conjunction with the horizontal
depth gauge.
4. Digital Tachometer/Hourmeter – Indicates engine RPM's
and operational hours saw has been in use.
5. Engine ON/OFF Switch – Pull this switch to permit the
engine to be started by pull rope. Push the switch inward to
stop the engine.
