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 en open area
．
Avold 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 underthe gas tank
all the way
．
Position the engine stop switch
，
located
on the engine, to run. Open the throttle approximat-
ely 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
．
Cautlon-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 ruel 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
．
AII
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
．
Step on the left side of PEDAL untiI 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 cutter
handles to follow cutting line
