stated operation is considered contrary to designated use. The
risk of such use lies entirely with the user. The manufacturer
cannot be held liable for damages as a result of misuse.
This saw is not intended for wet cutting. (The use of water sprayed
onto the tool [blade] during the cutting operation).
FAMILIARIZATION
This SFCG1-6H MiniCutter Saw is designed for dry sawing of
concrete slabs utilizing diamond blades. The saw has been
engineered for general and industrial flat sawing applications
that include: Joint Sawing of Green Concrete, Decorative
Sawing in Cured Concrete, Light Demolition Sawing and "V"
Groove Beveling. The simple and compact nature of the
SlabSaver makes it a perfect sawing tool for one person to
operate and transport. The saw combines inno vative f eatures,
top quality components, and a committed attention to state-ofthe-art manufacturing.
For peak performance, the SlabSaver has been engineered to
operate a powerful 6.5 HP Gasoline engine and 10" diameter
diamond blades. This special design allows f or fast/clean cuts
in different materials at depths from 1/4" to 3 1/4".
Heavy-duty front and rear axles, polyurethane wheels with
permanently sealed ball bearings, and solid undercarraige
assembly provide years of reliable use. The SlabSaver
incorporates an innovative P osiLok raise/lower control assemb ly
that provides fingertip control of blade orientation, infinitely
adjustable locking blade depth control, and depth feed gauge.
Retractable front & rear pointers with "tracking wheels" are
provided to support precise straight sawing. This system permits
the operator to quickly adjust the blade cutting depth and
safeguard against "blade-creep" during sawing operations. For
operator comfort and ease of transportation & storage, an
adjustable locking handle bar is provided.
Operator control of the saws is safely accomplished with
adjustable handle bars, and a conveniently oriented raise/lower
lever and depth adjustment wheel. An engine-off switch (Item 22
Fig. 3) located next to the handle lock allows the operator to
safely turn the engine off from the operator's position and away
from moving parts.
ENGINE
Pages 23-27 highlight fundamental aspects of engine inspection,
starting, and shutdown. Refer to the engine Owner's Manual for
specific instructions regarding operation, service and
maintenance.
For maximum performance and return on investment use:
Diamond Blades.
The jig-welded reinforced heavy gauge steel frame and chassis
assembly are designed to eliminate operational bending and/or
flex that would lead to diminished blade performance. Also, the
frame's general weight-to-strength ratio and center mounted
blade design ensure accurate tracking in the cut.
A robust blade shaft bearing assembly ensures minimal flutter
and shaft harmonics providing the most advantageous
conditions for a diamond blade at operating speeds.

blade usage for material.
WARNINGWARNING
WARNING
WARNINGWARNING
Failure to thoroughly inspect the
diamond blade (Figure 11) for
operational safety could result in
damage to the blade, the saw , and ma y
cause injury to the user or others in the
operating area. All damaged blades
must be discarded.
1.Drive Pin Hole – A commonly located hole on the diamond
blade core that prevents operational blade slippage
between the inner & outer blade flanges (collars). Inspect
the diameter of the hole to ensure there is no distortion,
and that a snug fit develops between the hole and drive
pin.
2.Stress Relief Holes (Gullets) –
cracks that may have propagated from the slots and/or
gullets. Cracks indicate extreme fatigue failure and if sawing
continues, catastrophic failure will occur.
3.Edge Of The Steel Core – Check the diameter edge for
discoloration (blue oxidation) indicating an overheating
condition caused by insufficient cooling water/air.
Overheating of blades may lead to loss of core tension
and/or increase the possibility for blade failure. Check to
make sure the steel core’ s width is unif orm about the rim of
the blade, and not succumbing to an “under cutting”
condition brought about by highly abrasive material or
improper under cutting core protection.
4.Directional Arrow – Check to ensure that the blade is
oriented properly on the blade shaft for sawing. Reference
the directional arrow in the blade and place it so the direction
of rotation “downcuts” with the turn of the shaft.

Use these procedures only if the pointer or guide are suspect of
being out of alignment.
1.Chalk out a straight line on the prepared slab or cutting
surface.
2.Use a 4 foot straight-edge or level by placing it flat against
the blade.
Check daily for any oil and/or fuel leakage, thread nut & bolt
tightness, and overall cleanliness.
Engine oil:
Check daily. Inspect with blade removed and saw frame
level on a level surface. Keep the oil clean, and at the proper
servicing level (Figure 8). DO NOT OVERFILL! SAE 10W -
30 of SG is recommended for general use.
Engine oil change:
Change engine oil the first month or 20 hours of operation.
Then every 3 months/or 50 HOURS of operation. See Engine
Owner’s Manual f or detailed information.
SFCG1 CONCRETE SAW — MAINTENANCE
Engine tank & strainer:
Clean every year/or 300 hours.
Fuel line:
Replace every two years/or as necessary .
Spark plug:
Clean/adjust every 6 months/or 100 hours. Replace every
year/ or 300 hours.
Chassis Lubrication
Regular lubrication of various components of the SFCG1 Saw
are critical to ensure a reasonable service life. Lubricate the
following components:
Drive Belt
Refer to pages 17 to 18 of this manual for Drive Belt adjustment
procedures and Removal and Replacement procedures.
Blade Shaft Bearings
Two z erk fittings are located at the lower-front area of the saw.
Lubricate before daily use. Use a good quality automotive or
general purpose grease. Check and lubricate more often if unit
is under heavy use. Do not overfill bearings. Overfilling can
damage the grease seals which can result in bearing exposure
to dirt and contaminants which can then shorten the life of the
bearings. Excess grease can also drip onto the cutting surface.
Engine Oil Change
Drain the used oil while the engine is warm by the following:
Refer to Figure 27.
1.Place an oil pan or suitable container below the engine drain
plug to catch the used oil.
2.Remove the filler cap/dipstick and the drain plug.
3.Drain the oil completely and reinstall the drain plug. Ensure
the drain plug is tightened securely .
NOTE
4.Make sure the engine is in a level position and fill to the outer
edge of the oil filler hole with the recommended oil. (See
T ab le 5.) Engine oil capacity is 0.63 US quart (0.60 liter).
Running the engine with a low oil level can cause engine
damage.
CAUTIONCAUTION
CAUTION
CAUTIONCAUTION
Dispose of used oil properly. DO
NOT pour used oil on the ground,
down a drain, or throw in the trash.
Used oil can generally be taken to
your local recycling center or
service station for reclamation.
