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.

CONCRETE SAW OPERATING INSTRUCTIONS
MAINTENANCE INSTRUCTIONS
1. Lubricate the blade shaft bearings daily! If
cutting dry, lubricate blade shaft bearing two or
three times daily. All other fittings (wheels,
bearings, depth control shaft, etc.) should be
greased every 40 hours of operation. Use only
premium lithium-based grease conforming to
NLGI No. 2 consistency.
2. Check the engine oil daily. Keep oil clean and
at proper level. Since the engine often operates
at an angle, check the engine oil level (with the
engine horizontal) frequently to ensure that the
oil level never fails below the minimum mark on
the dip stick. Follow the engine manufacturer’s
recommendations for changing oil.
3. Air filter.When cutting dry, clean two or three
times per day. See engine manual for
additional information.
4. Blade shaft V-belts tension: This model
concrete saw is equipped with 3VX premium V-
belts. These belts are properly tensioned at the
factory. Severe damage or even breakage of
the crankshaft might occur if the belts are
tensioned too tight. Check belt tension as set on
the new saw and never set belts beyond original
factory tension. Not enough tension will result in
poor saw performance and short belt life. Belts
should never be allowed to slip. After four hours
of use, re-tension belts to make up for initial
stretch. To re-tension the belts, turn the engine
off. Loosen the four bolts on the sides of the
engine base. Turn the vertical tensioning bolt on
the front of the engine base clockwise until the
belts are tight. Re-tighten the four bolts on the
engine base. Continue to check the belt tension
on a daily basis, and re-tension as necessary.
To obtain accurate V-belt setting, a V-belt
tension tester should be used. Check the setting
on a single belt of a matched set of V-belts.
Apply load on the center of the span. Deflection
should be 3/16” with a 5 to 6 lb. load.
5. Tighten fasteners regularly: Nuts and bolts
may become loose particularly after the first few
hours of operation. Most fasteners on this unit
are metric. Please use the correct tool
6. Engine care: See engine manual. Clean dust
and dirt from cooling fans, as required, to
provide adequate cooling.
GOVERNOR SPEEDS
It is critical that the governor and throttle on all internal
combustion engines are adjusted properly. Engine
speed is preset at the factory for proper sawing speed It
is not normally necessary to change this setting. It
should be periodically verified after the saw is placed in
service. To change governor setting, refer to the engine
manual.
WARNING: Over speeding the engine and
blade shaft can cause serious damage to the blade and
could result in injury to the operator and bystanders. Do
not exceed the following speeds: No load blade shaft –
2800 RPM, no load engine – 3900 RPM.
