CONCRETE SAW OPERATING INSTRUCTIONS
ASSEMBLY
1. Set handles to desired height and securely
tighten bolts.
2. Be certain to check engine oil level and service
if required. Refer to engine manual for
detailed information.
3. On electric saw models, the proper size power
cord must be provided by the purchaser.
GENERAL INSTRUCTIONS
1. Be certain you have the correct diamond or
abrasive blade. Contact your authorized
servicing dealer for the correct specification.
Getting the correct blade will make a
tremendous difference in your blade costs and
performance.
2. The blade shaft flange and arbor must be
inspected for damage and cleaned before
mounting the blade. If damaged, replace bad
parts. Inspect blade for damage to arbor hole
and flange area before attempting to mount
blade.
3. Mount the blade solidly and firmly on the blade
shaft arbor using the wrench provided. The lock
pin(s) in the outer blade flange must go
completely through the blade and into the
matching hole(s) in the inside blade flange.
Tighten the blade flange bolt very securely
(Approximately 50 lb.ft.). Note that the blade
shaft bolt on the right hand side has left hand
threads, which tightens by turning counter
clockwise.
4.
WARNING:
Do not operate without proper
blade guard in place. Do not operate with front
of blade guard raised. Blade exposure cannot
exceed 180 degrees when cutting.
5. The front pointer must be checked for alignment
with blade. It must be in line with a blade
mounted shaft. Use a chalk line or a long
straight edge to verify alignment.
6. Do not use conventional (wet) diamond blades
without water! You must have from 2-1/2 to 5
gallons of water per minute flowing over the
blade for proper cooling and to get maximum
blade life. For wet sawing, are sure the spray
holes in the blade guard tubes are open and that
each side of the blade has an adequate supply
of water. Test your water supply for pressure
and flow before starting to saw.
7. Saw in a straight line. Mark the cutting line
clearly so the saw operator can follow the line
without difficulty. The saw should not be twisted
from side to side trying to force the blade back
on line.
8. Saw only as deep as the specifications and job
conditions require. This will save blade life and
reduce sawing costs. Sawing excessively deep
is wasteful and should be avoided. Step cut in
increments of 2 inches for best results.
TO START SAW
1. Fill the fuel tank and check the engine oil level.
Refer to the engine manual for details.
2. Start engine. Follow procedure in engine manual.
3. Let engine warm up at half throttle.
4. All sawing is done at full throttle. Governor is
factory set for correct engine speed.
TO STOP SAW
Push and hold down the stop button at the right,
center of the control panel until the engine
completely stops.
TO MANEUVER SAW
1. Raise blade as high as possible so blade will not
strike pavement when maneuvering. Push
handle towards ground while squeezing depth
control lever. Release lever when height has
been reached.
2. To turn, lift rear wheels just above pavement
and maneuver saw as desired.
TO START SAWING
1. Align blade with cut.
2. For wet sawing open water valve
Full
open.
Confirm flow and adjust before lowering into cut.
If water supply is interrupted, stop cutting
immediately.
3. Lower blade into cut (never deeper than
required) by squeezing depth control lever.
When the
blade reaches desired depth, release
lever.
4. During cutting do not exert excessive side
pressure on handles to steer. Use only enough
pressure to follow previously marked line.
5. Move the speed control handle forward until
desired speed is obtained allowing the blade to
cut and not climb out of cut or stall.
6. If the saw should stall for any reason raise the
blade completely. When lowering the blade into
a partially-made cut, use extreme care to be
certain the blade is perfectly aligned within the
cut before starting to cut again. Do not force
blade into material by lowering blade to fast or
by propelling too fast while sawing.
AT FINISH OF CUT
1. On self-propelled models, move speed control
lever to neutral position.
2. Bring the blade out of the cut squeezing depth
control lever while pushing handle towards the
ground. Raise blade high enough to clear the
pavement when maneuvering the saw.
3. Turn off water valve. .
4. Close engine throttle to idle position. Let engine
cool down before stopping.
5. Do not leave the saw until the blade and saw have
completely stopped.
