4. Place the Chock Lever in the
“
CLOSED
”
position.
5. Rotate the throttle lever halfway between Fast
and Slow for starting. All sawing is done at
full throttle. The engine governor speed is
factory set to ensure optimum blade operating
speeds.
6. Grasp the starter grip and slowly pull it out.
The resistant becomes the hardest at a certain
position, corresponding to the compression
point. Pull the starter grip briskly and smoothly
for starting.
7. If the engine has started, slowly return the
choke lever to the
“
OPEN
”
position. If the
engine has not started repeat steps 1 through
5.
8. Before the saw is placed into operation, run
the engine for several minutes. Check for fuel
leaks, and noises that would associate with a
loose guards and/or covers.
9. Rotate the throttle lever toward full throttle.
10. To begin sawing, lower the rotating blade
allowing it to cut to the present depth.
11. When blade has reached full cutting depth,
slowly walk behind the saw at a rate that will
allow the engine to operate without losing
optimum RPM.
12. When the end of the cut has been reached,
raise the blade out of the cut by pulling back
on the handlebars (using a downward
pressure) until the raise/lower rod drops into its
slot with the blade in the raised position.
13. If cutting is complete, shut the saw down using
the following
“
Shutdown Procedures
”
.
TO STOP THE ENGINE
To stop the engine under normal conditions:
1. Place the engine throttle lever in the Slow
position, and listen for the engine speed to
decrease. Allow engine to run for 2 or 3
minutes for proper cool down.
2. Turn the engine Shutdown switch to the
“
OFF
”
position.
3. Turn the engine ON/OFF switch to the
“
OFF
”
position.
4. Place the fuel valve lever to the OFF
position.
GUARDS, COVERS & V-BELTS
Blade Guard Check
CHECK the following on the
“
blade guard
”
1. Ensure the capacity of the blade guard
matches the diameter of your diamond
blade.
2. Check that the guard is bolted firmly upon
the saw frame.
3. Check that the spring tensioned front cover
of the guard is firmly seated with the rear
section of the guard, and there are no gaps.
NEVER lift the blade guard while cutting.
V-belt Alignment and Tensioning
1. Remove the bolts that secure the V-belt
cover to the saw frame.
2. Check uniform parallelism of V-belt and
pulley (sheaves). Use a straight-edge or
machinist
’
s square against both pulleys and
adjust both pulleys until equally aligned.
3. DO NOT over or under tighten the V-belt.
Severe damage can occur to the saw and
engine
crank
shaft
if
the
belt
is
over-tensioned. A decrease of power to the
blade and poor performance will result if
the belt is under-tensioned (loose on
pulleys).
