INTRODUCTION
The 50 Handheld is intended primarily for finish cuts, scoring and decorative applications, and is
designed for ease of use and convenience. It is not intended for metal or wood cutting. Much like the entire
line of Husqvarna Soff-Cut saws, the handheld saw works in conjunction with the Husqvarna Excel Series
diamond blades and patented skid plates to allow for Ultra Early Entry cutting, which minimizes chipping
and spalling while getting the job done the same day. The patented Soff-Cut Ultra Early Entry dry cutting
system controls random cracking of concrete through the early timing of the saw cutting usually within one
to two hours after the finishing process is complete. The low dust blade guard system with integrated dust
extraction port allows the saw to cut dry and it controls the debris for little or no clean up when used with a
vacuum system.

XL5-5000A-X50
Medium hard to soft aggregate, abrasive sand
(Red Blade also available in 0.225” (5.72mm) widths)
BLADE AND SKID PLATE INSTALLATION
WARNING
Step 3
Install a new skid plate (G) by sliding the front into the angled
slot of the lower blade guard (H) and firmly against the depth
stop washer (I). Push the rear of the skid plate up into the
threaded stud at the rear of the lower guard and screw on the
skid stop washer (J). Hand tighten only.
Disconnect the unit from the power source before
making any adjustments or changing blade and skid
plate.
Step 1
Remove the blade cover (A) by turning the two metal knobs
counter-clockwise. While holding the spindle lock button (B),
remove the blade bolt (C) by turning it counter-clockwise using
a 1/2” wrench. Remove the blade flange (D). Inspect the blade
(E) for any damage.
Step 4
Raise the lower guard and check that the blade does not contact the skid plate. When replacing a worn blade, thoroughly
clean the concrete from the blade guard (upper and lower
guard) and blade cover before installing the new blade.
WARNING
A new skid plate is included with every new blade. Make sure
to remove and discard the old skid plate and replace it with a
new skid plate every time the blade is replaced.
Do not use any blade that has cracks, nicks, flaws or
a damaged arbor. Make sure the blade is marked with
a maximum operating speed greater than 11,000 rpm.
Use only dry cutting concrete diamond blades.
NOTE:
The patented skid plate is the most important part of the
Soff-Cut Ultra Early Entry system. If it is bent, twisted or
damaged, spalling and raveling of a cut may result. Store
skid plates carefully and install them properly. Install a
new skid plate with each new blade. Never re-use skid
plates.
Step 2
Match the blade tri-arbor (E) to the blade shaft arbor (F) and
install the blade firmly against the rear flange (F). Insure the
blade is installed on the tri-arbor correctly. Match the female triarbor of the blade flange with the tri-arbor blade shaft and install the blade bolt turning clockwise. Be sure the outer flange
is fully seated and firmly holding the diamond blade in position.

OPERATING INSTRUCTIONS
The saw is factory set to full depth-of-cut, typically 1” (25.4
mm) with a brand new blade. If a shallower depth of cut is
desired, such as for architectural scoring and decorative application, adjust blade depth by turning the depth adjust thumb
screw (D) approximately one full turn counter-clockwise. Slide
the depth adjust arm (E) to the desired depth using the depth
indicator label (B). Tighten the depth adjust thumb screw (D)
by hand to lock the depth arm in place. Rotate the front guide
(A) down to the forward position.
ON-OFF paddle
switch
Handle
Line up the saw with the cut line using the “S” notch (F) on the
lower guard (N) and the triangle pointer at the rear of the lower
blade guard. Make sure the skid plate lies flat on the concrete
with the rear wheel (J). Flip the lock-off button and simultaneously squeeze the paddle switch (L) to turn “ON” the saw
NOTE: Pressure must be maintained continuously on the
paddle switch to keep electric motor running.
Rotate the saw down slowly to plunge and lower the blade in
the concrete. Push the saw forward to cut, keeping the front
guide wheel on the cut line. Do not force the saw; let the diamond blade to work.
Front guide wheel
Experience is very important when running the 50 Handheld
saw. A skilled worker is highly recommended. Always do an
inspection of the saw before using it. Insure all guards are
secure, undamaged, and properly installed and that the spring
loaded lower blade guard swings open and closes freely without binding.
WARNING
Do not operate the saw unless all guards, safety
equipment and the engine kill switch are in place and
operational!
When approaching a wall, raise the front guide and use the “S”
notch and the triangle guide at the rear of the blade guard to
cut the last few inches.
At the end of the cut, rotate the saw up to raise the blade out
of the cut, without lifting the skid plate off the concrete. The
skid plate must remain flat on the concrete until the blade is
completely out of the concrete. NOTE: Do not release the
paddle switch or switch off the saw while the blade is in
the concrete; doing so will cause the saw cut to ravel and
spall. Do not walk on the joints or transport equipment
across the joints until the concrete fully hardens.
WARNING
Position the power cord clear of the intended saw cut. Do
not wrap the cord around your arm or wrist. Check for proper
specification of blade and that the skid plate operates properly.
Check that the blade and skid plate are in good condition.
Make sure the work site is clean, well lit and hazard free.
Do not leave the saw unattended while the engine
is running! Always secure the saw from movement
while unattended.
WARNING
Husqvarna Soff-Cut recommends the use of a vacuum
system when using the 50 Handheld saw. The integrated
dust extraction port (M) is designed for easy attachment of
standard 1 1/2 (38 mm) vacuum hose. The vacuum system
allows the saw to function at its peak efficiency, making for a
high quality saw joint with the additional benefit of little or no
cleanup required (of the saw and/ or saw joints) and marked
reduction in breathable airborne dust.
Before each use, carefully inspect the 50 Handheld
for any damage to any of its parts and components.
Under no circumstance should the 50 Handheld or
any of its attachments be operated if you find damage or are suspicious that something appears to be
damaged.
GENERATORS AND EXTENSION CORDS
If an extension cord is necessary, a cord of adequate size conductors that is capable of carrying the current necessary for your
tool must be used. Replace damaged or worn out cords immediately. Refer to the chart for the correct size to use. If in doubt,
use the next heavier gauge. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating.
When using a generator, Husqvarna Soff-Cut recommends a generator with minimum rating of 2800 Watts and a 20 Amps circuit
breaker.

Choose the correct specification of ProEdge Blade based on the width of the pre-existing control joint as follow:
USING THE PROEDGE SERIES BLADES
Step 2
Set the depth adjust arm firmly against the depth stop bolt and
tighten the depth adjust thumb screw to set the depth. Remove
the guide wheel and reinstall with the shoulder against the
guide arm (See illustration: Guide wheel installation).
Follow the instructions for installing a Excel series blade and
skid plate when installing a ProEdge blade.
NOTE:
The ProEdge blade requires its own unique skid plate to
function properly.
Step 1
Adjust bevel depth of cut by loosening the depth adjust arm.
Pull up on the lower guard until the proper amount of blade
protrudes below the skid plate. (See figure below for proper
depth).
Step 3
Line up the saw by pushing down on the saw lower the blade
into the existing cut. Use the “V” notch on the front of the
lower guard to fine tune alignment. Flip the lock-off button and
squeeze the paddle switch to turn “ON” the saw. Allow the
blade to reach maximum speed the rotate the saw down to
plunge the blade into the concrete until the depth adjust arm
bottoms down against the depth stop bolt.
Step 4
Push the saw forward to cut, keeping the guide wheel on the
cut line. Maintain an even cutting speed for best results.

WARNING
Do not modify the saw! Use only Husqvarna Construction Products replacement parts. Use of unauthorized
parts may create a danger or damage the engine.
MAXIMIZING THE SOFF-CUT SYSTEM
“ The timing of concrete operations - especially finishing 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 SoffCut is being specified 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 “specification”:
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 significant 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 floor finishing, sometimes within 0 to 2 hours...if the cut is sawn within a few hours after the final finishing,
random cracking can be controlled...”
Husqvarna has the only Ultra Early Entry dry-cutting system (Soff-Cut) which controls random cracking through the early timing of the cut. With the patented Soff-Cut method, control joints are usually cut within 0 to 2 hours after the finishing 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 final 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 finished product that they expect.
We hope this information is beneficial to building owners, general contractors, concrete finishers, saw operators and the
entire industry. For additional information, contact Husqvarna Construction Products at (951) 272-2330 or (800) 776-3328, or
see our website www.husqvarnacp.com.

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.
RECOMMENDED CONTRACTION JOINT SPACING
