(2E)   Follow our instructions strictly and your ma-   chine will give you long service in normal operating   WARNING: DO NOT operate the saw with the   front of the Blade Guard (2H) raised!   1 Features   Use: Wet sawing of old and new concrete and asphalt.   Tools: Diamond blades — water cooled, Ø: 10", 12", 14",   18" and 20" with Arbor Ø - 1"   WARNING: Blade exposure CANNOT exceed   180 degrees when operating!   (For information, contact your Husqvarna supplier)   CUTTING DEPTHS   • • The Front Pointer must be checked for alignment with   the Blade (2E). It must be in line with the Blade (2E)   mounted on the Blade Shaft (2I).   MAXIMUM   BLADE DEPTH   (To Collar)   MC18   BLADE SIZE   MAXIMUM DEPTH   (To Depth Stop)   2 1/2" (62mm)   3-1/2" (87mm)   4-1/2" (112mm)   6-1/2" (158mm)   10" (250mm)   12" (300mm)   14" (350mm)   18" (450mm)   2 3/4" (68mm)   3-3/4" (93mm)   4-3/4" (118mm)   6-3/4" (164mm)   For WET SAWING, be sure the water jets in the blade   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 (flow) before   starting to saw.   Before starting up the machine, make   sure you read this entire manual and are   familiar with the operation of this   machine.   WATER FLOW from 2-1/2 to 5 gallons of   water per minute MUST flow over the blade   to properly cool it and to get maximum blade   life. DO NOT use conventional (wet) diamond   blades without water!   The working area must be completely clear,   well lit and all safety hazards removed.   • • Saw only as deep as the specifications and job   conditions require. Sawing excessively deep is   wasteful–avoid it! Step cut in increments of 2 inches   (50 mm) for best results.   The operator must wear   p r o t e c t i v e c l o t h i n g   appropriate to the work he   is doing.   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 try-   ing to force the blade back on the line.   Any persons not involved in the work, should   leave the area.   Use only blades marked with a maximum   operating speed greater than the bladeshaft   speed.   12   Download from Www.Somanuals.com.

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.   • 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.   5 Fitting The Blade   3. Start the engine. Refer to the engine manual for detailed   information.   (See Fig. 1 and 2)   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.   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).   WARNING: To STOP ENGINE, PUSH the   Engine Stop Switch DOWN, located on the   handle support of the saw. [Wait for all engine   movement to stop.]   • • • • Fit Diamond Blade (2E) on the Blade Shaft Arbor.   Install Outer Flange (2B) into the Blade Shaft (2I)   makingsurethattheLockingPin(2D)passesthroughthe   Diamond Blade (2E) and into the Inner Flange (2F).   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 back-   lash.   Install and tighten Blade Flange Nut using the Blade   Shaft Wrench [50 lb.-ft. (68 N-m)] while firmly 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.   13   Download from Www.Somanuals.com.

Raise the blade (2E) high enough out of   the cut to clear the pavement when maneuvering the   saw.   Raise the Blade (2E) as high as possible so that   the Blade (2E) will not strike pavement when   To Start Sawing   • • • Turn off the Water Valve (1A).   • • Follow all of the instructions outlined above.   Open the Water Valve (1A) FULL open. Check the   water to verify full flow, then adjust for proper amount   of water on the blade BEFORE you lower the Blade.   Turn the Engine Throttle to the IDLE position.   STOP the engine by turning the Engine Switch (1D)   to the OFF position.   Test for adequate water supply [2-1/2 to 5   gal/min (10 to 20 lit./min)]. Low water flow will   cause damage to diamond blades.   If water supply is interrupted, stop cutting   immediately.   Screw Feed Version:   • Lower the blade into the cut by pulling up on the Depth   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.   • 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.   14   Download from Www.Somanuals.com.

It enables the MC 18 to cut   7/16" - 1/2" (11-12.7mm) wide.   After each use: CLEAN the machine.   WARNING: This special outer flange 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 flange assembly supplied with   the MC 18. The Special Outer Flange Assembly   can be identified by the COUNTERBORE on the   “Nut Side” of the flange. The Standard Outer   Flange Assembly has NO COUNTERBORE.   LUBRICATION:   LUBRICATE DAILY   Front Wheels and Blade Shaft Bearings   LUBRICATE EVERY 50 HOURS   Depth Control Adjustment Screw (Screw Feed Version   Only)   WATER TANK KIT   A 6 gallon (23 liter) Water Tank Kit is available as a   • 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 Disulfide.   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 sufficient wa-   ter flow available to properly cool the blades!   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 filter every 50 HOURS of operation.   Refer to the engine manual for detailed information.   TIE DOWN BRACKET KIT (P/N 167189)   • A Tie Down Bracket Kit is available as a field installed   accessory. The kit consists of two (2) tie down loops   that are installed at the front of the frame. They are to   be used only to SECURE the saw to a truck or trailer   during transport.   CLEAN ENGINE AIR FILTER:   Clean the air filter 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.   WARNING: DO NOT use the tie down   brackets as a device for lifting the saw!   15   Download from Www.Somanuals.com.
