INSTALLING BLADE
1. Be certain that the spark plug is disconnected or saw
is unplugged.
2. Remove the blade shaft nut, and take off outside blade
shaft flange.
3. Clean off any foreign particles on the clamping
surfaces of flanges and on the mounting surface of the
blade.
4. Place the blade on the blade shaft, lining up the offset
drive pin in the blade with the drive pin in the mounting
collar (if the pin system is available on the machine). If
your blade has a directional rotational arrow, position
arrow for down cut (diamond tail trailing for down cut).
5. Replace the outside blade shaft flange on the blade
shaft. Drive pin on the inside collar must project
through the drive hole in the blade and into the outside
collar (if the pin system is available on the machine).
6. Tighten the blade shaft nut securely against star
washer and outside flange, using wrench supplied.
7. Reconnect the spark plug or (with switch “off”) plug in
the electric supply cord.
TYPES OF CUTTING
Cut speed depends entirely on using the correct blade for
the material to be cut. Wet or dry, diamond blades of
various specifications are available for cutting concrete or
asphalt.
Before Starting/Cold Start/Hot Start/
To Start Cutting
BEFORE STARTING
1. Use correct blade for cutting conditions.
2. Ensure arbors and flanges are clean and undamaged.
3. Mount blade and tighten securely using wrench.
4. When wet cutting, check water jets for adequate flow.
5. Align pointer with cutter blade.
Caution – Set unit up in an open area. Avoid close
proximity to structures or other equipment. Failure to
do so may cause inadvertent injury to operator or
other persons in the area.
Cold start – Open the fuel valve under the gas tank all the
way. Position the engine stop switch, located on the
engine, to run. Open the throttle approximately half way
and apply the choke. Pull the starter rope sharply. When
the engine starts, open the choke and adjust the
throttle as necessary to keep it running. Allow the
engine to warm up for a few minutes before
placing it under the load. If the engine doesn’t
start after (3) pulls, open choke slightly to prevent
flooding. Always operate the engine at full throttle
when under load.
Hot Start– Open the valve under the gas tank all
the way if it has been shut off. Open the throttle
approximately half way. Do not apply the choke.
Pull the starter rope sharply until the engine
starts. When the engine starts, adjust the throttle.
Always operate the engine at full throttle when
under load.
NOTE: These starting instructions are general
guidelines only. Since many engine options are
available, consult the Engine Manual included
with this unit for specific instructions.
Caution – Gasoline Engines – To improve the
engine service life, allow the engine to idle
without load for (2) to (5) minutes before
shutting it down. When the idling period is up,
use the stop switch located on the engine and
turn it to stop. Close the fuel valve under the
gas tank. Engine flooding can occur if the
valve is left open during transport.
TO START CUTTING
1. Start engine and let engine warm up. All
cutting is done at full throttle.
2. Align blade and saw with cut. If wet cutting,
open water valve and turn water safety switch
on.
3. Step on the left side of PEDAL until hear a
“click”, then turn on the WHEEL HANDLE on
the top of the machine to remove the
equipment forward and reverse, step down
the right side of PEDAL to change to “push”
driving system.
4. Lower blade into cut slowly.
5. Cut as fast as blade will allow. If blade climbs
out of cut, reduce forward speed or depth of
cut.
6. Use only enough side pressure on saw
handles to follow cutting line.
