Operation
5.5 Maneuvering the Saw
NOTICE: Raise the blade as high as possible when maneuvering so that
the blade will not strike the pavement.
The blade is spinning whenever the saw is running.
The speed control lever for the hydrostatic transmission is adjusted
at the factory to provide approximately 40 ft/min maximum in forward
and 20 ft/min maximum in reverse with the engine running at full
throttle. When maneuvering, the engine needs to be at one-half
throttle or more so that the hydrostatic transmission can operate
efficiently.
When the TRANSMISSION LEVER is in NEUTRAL and the
DRIVE DISENGAGE LEVER is in the ENGAGE position, the
transmission is in NEUTRAL and the wheels are locked.
To engage the transmission push the engaging lever down on the
right rear of the console cowling. To disengage the transmission
pull the engaging lever up. When the saw is manually pushed, the
transmission must be disengaged. The transmission speed control
lever is located on the top of the console. This lever controls the
variable forward and reverse ground speed (up to 40 feet per minute)
of the saw.
When engaging the transmission with the engaging lever, be sure the
speed control lever is at the neutral position to avoid saw movement.
5.6 Wet Cutting
The water used on the blade is to provide coolant during cutting,
and to flush the concrete cutting from the cut. The water hose bibb
is located below the throttle control on the left side of the saw. After
connecting the water supply, turn on the water at the source and use
water valve on console to control flow of water to blade. Be sure that
both sides of the blade are getting adequate flow of water. The water
control adjustment allows the operator to manually control the flow of
water to the blade during all operations.
5.7 Dry Cutting
Dry cutting blades have been specially designed for use with concrete
saws. Ensure that the blade you are using is clearly marked for dry
cutting.
NOTICE:
When dry cutting, it is important to keep the air filter clean.
Check the condition of the filter at least every four (4) hours of
operation. Clean the pre-filter (wash in soapy water and re-oil) and
change the paper filter as soon as it becomes clogged. Concrete
dust is very abrasive, and will quickly damage internal engine parts,
causing loss of compression and eventual engine failure.
