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 cutter with cut. If wet
cutting, open water valve and turn water
safety switch on.
3. Lower blade into cut slowly.
4. Cut as fast as blade will allow. If blade
climbs out of cut, reduce forward speed or
depth of cut.
5. Use only enough side pressure on cutter
handles to follow cutting line.
