shaft in the blade block (C). Rotate the blade shaft counterclockwise with the wrench on the blade shaft bolt (B) while
pushing in on the blade shaft locking pin (D) located on the
front of the saw frame. The locking pin will drop in the blade
shaft and prevent the shaft from rotating.
Step 3
Remove the blade shaft bolt by continuing to turn the bolt
counter-clockwise. Remove the outer arbor washer or ange
(E).
WARNING
Inspect the blade (K) for any damage. Do not use any
blade that has cracks, nicks, aws or a damaged arbor.
Make sure the blade is marked with a maximum operating speed greater than 3200 rpm.
Step 4
Match the blade tri-arbor to the blade shaft arbor (F) and install
the blade rmly against the rear ange (F). Insure the blade is
installed on the tri-arbor correctly. Match the female tri-arbor of
the outer washer or ange with the blade shaft and install the
blade shaft bolt turning clockwise while holding the locking pin
in. Be sure the outer ange is fully seated and rmly holding
the diamond blade in position.
Step 5
Install a new skid plate (G) by hooking the front on the front
blade block shaft pin. Connect the rear blade block shaft and
the rear of the skid plate by installing the locking pin (H).
Step 6
Install the blade cover by turning the two knobs and tighten until fully seated against the blade block. Lift the front and rear of
the skid plate to insure the blade slides through the skid plate
freely.
Step 7
Insure the lexan shields (I & J) move freely up and down.

SAWING CONTRACTION JOINTS
As concrete hydrates or cures and begins to set, it develops internal stresses which may cause random cracks. Random
cracks cast doubt on the quality and workmanship of the concrete. Contraction joints are cut in concrete to relieve these
stresses before they seek their own relief in the form of random crack. The Soff-Cut Ultra Early Entry system controls random
cracking through the early timing of a saw cut at predetermined locations to create weakened planes in the concrete that
subsequently crack at the bottom of the cut to relieve stress. Husqvarna sawed contraction joints should be a minimum of
1/8th the concrete depth and a minimum of 1” (25mm) deep. Contraction joints should be sawn as soon as the concrete will
support the weight of the saw and the operator without marking or damaging the concrete. There are many possibilities for
joint layout. Joint layout should be provided, the saw contractor should submit a detailed joint layout for approval prior to cutting. Several factors affect joint spacing including:
• Concrete thickness
• Type, amount and location of reinforcement
• Shrinkage potential of concrete-cement (type, quantity), aggregate (size, quantity, quality), water to cement ratio,
admixtures, concrete temperature
• Base friction
• Slab restraints
• Layout of foundations, racks, pits, equipment pad, trenches, etc.
• Environmental factors - temperature, wind, humidity
• Methods and quality of concrete curing.
Generally, contraction joint patterns should divide slabs into approximate square panels per the recommended spacing
shown.

MAXIMIZING THE SOFF-CUT SYSTEM
“ The timing of concrete operations - especially nishing and jointing - is critical”, states a quote from the foreword of
the American Concrete Institute (ACI) 302.1 R-96. It goes on to say that “Failure to address this issue can contribute to undesirable characteristics in the wearing surface as cracking...” (It mentions other problems).
The patented Soff-Cut Ultra Early Entry system has revolutionized the method used to control random cracking. While Soff-
Cut is being specied more today than ever, sometimes the ultra early-entry spec is not always followed on the job site. In
order for the Soff-Cut system and an experienced Husqvarna contractor to do a satisfactory job, four components must exist
to meet the “specication”:
1. A Soff-Cut Ultra Early Entry dry up-cut saw
2. A Husqvarna Excel Series dry-cutting diamond blade
3. A Husqvarna anti-ravel skid plate installed with every new diamond blade
4. An operator skilled in using the Soff-Cut Ultra Early Entry cutting system.
Without this, joints can not be cut clearly enough to control random cracking before it starts, which is what the building owner
is paying for.
The ACI Spec 302.1R-96 says it best:
“Early-entry dry-cut saws use diamond-impregnated blades and a skid plate that helps prevent spalling. Timely changing of skid plates is necessary to effectively control spalling. It is best to change skid plates in accordance with manufacturer’s
recommendations...The goal of saw-cutting is to create a weakened plane as soon as the joint can be cut...The timing of the
early-entry process allows joints to be in place prior to development of signicant tensile stress in the concrete...”
The Portland Cement Association (PCA) engineering bulletin, Concrete Floors on the ground, also states:
“Proper jointing can eliminate unsightly random cracks. Aspects of joining that lead to a good job are choosing the
correct type of joint for each location, establishing a good joint pattern and layout, and installing the joint at the correct time...
Timing of joint sawing is critical...Lightweight, high-speed, early-cut saws have been developed to permit the joint sawing
very soon after oor nishing, sometimes within 0 to 2 hours...if the cut is sawn within a few hours after the nal nishing,
random cracking can be controlled...”
Husqvarna has the only Ultra Early Entry dry-cutting system (Soff-Cut) which controls random cracking through the early tim-
ing of the cut. With the patented Soff-Cut method, control joints are usually cut within 0 to 2 hours after the nishing process.
Joint cutting should begin as soon as the concrete will support the weight of the saw and the operator at each joint location
and before nal set. If the joints are not being cut within this time frame then the Soff-Cut Ultra Early Entry method is not being followed and building owners are not getting what they are paying for or the nished product that they expect.
We hope this information is benecial to building owners, general contractors, concrete nishers, saw operators and the
entire industry. For additional information, contact Husqvarna Construction Products at (951) 272-2330 or (800) 776-3328, or

TROUBLESHOOTING
SAW IS SPALLING AND RAVELLING CUT
- Check to see if the diamond blade is worn out, glazed,
warped or damaged.
ENGINE WILL NOT START
- Check that the red emergency stop button is pulled up.
- Insure skid plate moves freely up and down the entire shaft
length without contacting the diamond blade.
- Check skid plate for excessive wear or gap around the
diamond blade.
- Check skid plate for tension or loose mounts. Skid plates are
preset at the factory.
- Check bottom of skid plate for metal burrs or irregularities.
- Insure skid plate is not twisted or bent.
- Check lexan covers for free movement up and down.
- Insure there is spring down pressure at each end of the skid
plate.
- Do not twist or move the saw sideways while cutting.
- Check that the engine is running properly and at full throttle.
- Check belt and belt idler for proper tension.
- Insure the diamond blade is properly mounted and secured
with clean anges.
- Insure that the diamond blade is the correct specication for
your area.
- Insure the slab is in clean with no debris that could raise the
skid plate or saw while cutting.
- Use Husqvarna joint protectors at all cut intersections.
- Clean excess concrete debris from the blade block assembly.
- Check that the scrapers in the blade block are not bent or
binding.
- Insure that the blade block shafts are not bent or damaged.
- Check that the front diverter in the blade block is not bent and
the diverter legs are not contacting the concrete.
ENGINE RUNS ROUGH, BACK FIRES OR CAN NOT
REACH FULL SPEED
- Check if there is fuel in the tank and it is the correct fuel.
Make sure there is no water in the fuel.
- Check that the spark plug wires are connected to the spark
plugs.
- Engine is ooded. Adjust the choke per the engine owner’s
manual.
- Check that the air lter is not dirty or plugged.
- Check the choke is in the “on” position for cold starts. Adjust
the choke per the engine owner’s manual.
- Check that the blade shaft rotates freely and no concrete has
built up in the blade block.
- Check that the fuel valve is turned the “ON” position.
- Oil level is too low. Engine is equipped with an oil alert
system that will not let the engine start unless the engine oil
level is within the correct range.
SAW PULLS TO ONE SIDE WHILE SAWING
- Check front and rear guide is properly aligned with the center
of the diamond blade.
- Check to see if diamond blade is worn out, glazed, warped or
damaged.
- Do not twist or move the saw sideways while cutting. Make
gradual changes in pressure on the handlebar to control the
saw in the cut.
- Insure that all wheels rolls freely and smoothly.
- Do not force the saw. Allow the diamond blade to cut at its
own rate of speed.
- Check the skid plate for damage or burrs.
- Insure both driver tubes are contacting the rear wheels,
driver tubes are clean and rear wheels are not damaged.
- Check if there is fuel in the tank and it is the correct fuel.
Make sure there is no water in the fuel.
- Check that the spark plugs are clean and properly gapped.
- Check that choke is in the “off” position after engine is warm.
- Check that air lter is not dirty or plugged.
- Check that the throttle lever is properly set.
- Check for correct oil level. Engine oil alert system may func
tion intermittently if oil level is not within the correct range.
