blade guard over the Blade! (2E)
WARNING: DO NOT operate the saw with the
front of the Blade Guard (2H) raised!
WARNING: Blade exposure CANNOT exceed

mounted on the Blade Shaft (2I).
guard water tubes are open and that each side of the
Blade (2E) has an adequate supply of water. Test the
water supply for pressure and quantity (fl ow) before
starting to saw.

wasteful–avoid it! Step cut in increments of 2 inches
(50 mm) for best results.
the saw operator can follow the line without diffi culty .
The saw should NOT be twisted from side to side trying to force the blade back on the line.

Check Before Starting
6 Starting The Power Source
Always pay extreme care and attention to the
preparation of the machine before starting.
T ake into account the working conditions from
the health and safety point of view.
FUEL: Check the engine maintenance manual.
* Gas Models: Unleaded gasoline is recommended.
• Check that the engine oil level is correct. Because
the engine often operates at an angle, check the oil
level (with engine horizontal) frequently to ensure that
the oil level never falls below the lower mark on the
dipstick. 10W30 oil is recommended.
5 Fitting The Blade
(See Fig. 1 and 2)
Always set the Engine Switch (1D) to the "OFF"
position before mounting the Blade (2E).
• Set the Engine Switch (1D) to the "OFF" position.
• Raise the machine to a high position [by cranking the
Raise/Lower Hand Wheel].
• Raise the front half of the Blade Guard (2H).
• Unscrew the Blade Shaft Nut (2A). Remove Outer
Flange (2B).
• Fit Diamond Blade (2E) on the Blade Shaft Arbor.
• Install Outer Flange (2B) into the Blade Shaft (2I)
making sure that the Locking Pin (2D) passes through the
Diamond Blade (2E) and into the Inner Flange (2F).
Remove all wrenches and tools from the fl oor
and the machine.
Always keep blade guard and transmission
guard in place.
On Gasoline Engine Models:
1. Refer to the engine operating manual for proper engine
operation.
2. Fill the engine fuel tank and check the engine oil level.
Refer to the engine manual for detailed information.
3. Start the engine. Refer to the engine manual for detailed
information.
4. Let the engine warm up at half throttle. All sawing is
done at full throttle. The governor is factory set for the
correct engine speed. Do not change the Governor
setting – it is factory set for the correct speed.
WARNING: To STOP ENGINE, PUSH the
Engine Stop Switch DOWN, located on the
handle support of the saw. [W ait for all engine
movement to stop.]
Note the direction of rotation of the blade. The
direction of rotation is shown by an arrow on
the Diamond Blade (2E). Make sure that the
contact surfaces on the Diamond Blade (2E),
Inner & Outer Flanges (2B & 2F) and Blade
Arbor are clean.
• Rotate Outer Flange (2B) and the Blade (2E) in the
opposite direction of blade rotation to remove backlash.
• Install and tighten Blade Flange Nut using the Blade
Shaft Wrench [50 lb.-ft. (68 N-m)] while fi rmly holding
the Diamond Blade (2E).
• Lower front half of Blade Guard (2H).
The Blade Shaft Nut (2A) on the Right Hand
side has Left Hand threads.

To Maneuver the Saw
9 Stopping the Saw
• Set the handle bar height to a comfortable position.
• Raise the Blade (2E) as high as possible so that
the Blade (2E) will not strike pavement when

• Follow all of the instructions outlined above.
• Open the Water Valve (1A) FULL open. Check the

water to verify full fl ow, then adjust for proper amount
of water on the blade BEFORE you lower the Blade.
Test for adequate water supply [2-1/2 to 5
gal/min (10 to 20 lit./min)]. Low water fl ow will
cause damage to diamond blades.
If water supply is interrupted, stop cutting
immediately.
Control Lock (1E) and slowly turning the Hand Wheel
COUNTER-CLOCKWISE. When the desired depth of
cut is reached, push Depth Control Lock down to lock
it in the hand wheel.
• Screw Feed Version:
Raise the blade out of the cut by pulling up on the
depth control lock and slowly turning the hand wheel
clockwise. Raise the blade (2E) high enough out of
the cut to clear the pavement when maneuvering the
saw.
• Turn off the Water Valve (1A).
• Turn the Engine Throttle to the IDLE position.
• STOP the engine by turning the Engine Switch (1D)
to the OFF position.
• During cutting, DO NOT exert excessive side pressure
on the Handle Bars to attempt to “STEER” the saw.
Use only enough pressure to follow the previously
marked line.
• If the saw should stall for any reason, raise the blade
completely out of the cut before starting your power
source again!
• When lowering the Blade (2E) into a partially made
cut, the blade must be perfectly aligned within the cut
before starting to saw again. DO NOT FORCE the
Blade (2E) into the material by lowering the Blade too
fast, or by propelling the saw too fast.

10 Maintenance
11 Optional and Accessory (Field Installed)
Before performing any maintenance, ALWAYS
park the machine on a level surface with the
Engine OFF and the Engine Switch in the "OFF"
position.
After each use: CLEAN the machine.
LUBRICATION:
LUBRICATE DAILY
Front Wheels and Blade Shaft Bearings
LUBRICATE EVERY 50 HOURS
Depth Control Adjustment Screw (Screw Feed Version
Only)
NOTE: When cutting dry , lubricate blade shaft bearings 2 or
3 times daily, the grease provides an added protective seal
for the bearings. Use only a Premium Lithium 12 based
Grease, conforming to NLG1 Grade #2 Consistency , without
Molybdenum Disulfi de.
ENGINE OIL:
Check daily. Keep the oil clean and at the proper level.
10W30 MS, SD, SE or better is generally recommended.
Capacity levels indicated on page 10. DO NOT OVERFILL!!
Change engine oil and oil fi lter every 50 HOURS of operation.
Refer to the engine manual for detailed information.
CLEAN ENGINE AIR FILTER:
Clean the air fi lter 2 or 3 times daily when dry cutting. Refer
to the engine manual for detailed information.
ENGINE CARE:
Refer to the engine manual for detailed information.
SPECIAL OUTER FLANGE ASSY 1/2" (12.7mm)
WIDE CUT (P/N 167963)
• A Special Outer Flange Assembly is available as a
fi eld installed accessory. It enables the MC 18 to cut
7/16" - 1/2" (11-12.7mm) wide.
WARNING: This special outer fl ange assembly
is for use with blade width stacks of 7/16" - 1/2"
(11mm-12.7mm) only! If blade width stacks of
less than 7/16" (11mm) are required, use the
standard outer fl ange assembly supplied with
the MC 18. The Special Outer Flange Assembly
can be identifi ed by the COUNTERBORE on the
“Nut Side” of the fl ange. The Standard Outer
Flange Assembly has NO COUNTERBORE.
WATER TANK KIT
• A 6 gallon (23 liter) Water Tank Kit is available as a
Field installed accessory. Use only for dry cutting!
The water tank is designed only to suppress airborne
concrete dust.
WARNING: DO NOT use conventional (wet)
diamond blades with the water tank as the
water source, because there is not suffi cient wa-
ter fl ow available to properly cool the blades!
TIE DOWN BRACKET KIT (P/N 167189)

DUST WARNING
Cutting, especially when DRY cutting, generates dust that comes from the material being cut,
which frequently contains silica. Silica is a basic component of sand, quartz, brick clay, granite and
numerous other minerals and rocks. Exposure to excessive amount of such dust can cause:
Respiratory diseases (affecting your ability to breath), including chronic bronchitis, silicosis
and pulmonary fibrosis from exposure to silica. These diseases may be fatal;
Skin irritation and rash; and
Cancer according to NTP* and IARC*
* Toxicology Program / International Agency for Research on Cancer
National
Take precautionary steps
Avoid inhalation of and skin contact with dust, mist and fumes;
Wet cut when feasible, to minimize dust;
Wear and ensure that all bystanders wear appropriate respiratory protection such as dust
masks designed to filter out microscopic particles. (See OSHA 29 CFR Part 1910.1200)
California Prop 65 Warning:
Use of this product can cause exposure to materials known to the State of California to cause cancer
and/or birth defects or other reproductive harm.
