HYDRAULIC SAFETY TIPS
MAINTAINING A SAFE WORK ENVIRONMENT
Establishing a safe working environment in and around your hydraulic equipment is just common sense. The easiest and most effective way to
avoid problems is to make sure associates understand their equipment, know how to operate it safely and recognize the danger it represents if
handled carelessly. A few things you must be aware of include:
1. PRESSURE: Hydraulic fluid under pressure is dangerous and can cause serious injury.
2. FLAMMABILITY: When ignited, some hydraulic fluids can explode and/or cause fires.
3. MECHANICAL: Hydraulic fluid creates movement, which causes parts of your equipment to move or rotate. Always be aware of what
you are doing.
4. MOISTURE: Use caution when operating in wet or high moisture conditions. Make sure all electrical fittings, switches, cords plus stain
reliefs are in good condition. Always unplug when not in use and when doing any service work.
5. ELECTRICAL: Faulty wiring can also be an electrical hazard. A regular preventive maintenance program should always include a wir-
ing check. Unplug batteries and/or charger before serving.
6. TEMPERATURE: Because this machine operates at a relatively low pressure, overheating is not common. If surface of tank becomes
too hot to touch by hand (above 130ºF, 55°C), shut off machine and allow to cool off.
PRESSURE
Our system runs at or below 2,000 psi. Never look for a leak when unit is under pressure. Using your hand could cause serious injury. A few
common ways to encounter hydraulic fluid under pressure include:
1. PINHOLE: Fluid under pressure can cause serious injury. It can be almost invisible escaping from a pinhole, and it can pierce the skin
into the body. Do not touch a pressurized hydraulic hose assembly with any part of your body. If fluid punctures the skin, even if no pain is
felt, a serious emergency exists. Obtain medical assistance immediately. Failure to do so can result in loss of the injured part or death.
2. LEAK: Keep fittings and hoses tight. Only check and service when not under pressure. Leaking hydraulic fluid is not only unsightly, it’s
hazardous. In addition to making workplace floors slippery and dangerous, leaks also contaminate the environment. Before cleaning an oil
spill, always check EPA, state and local regulations.
3. BURST: Whether due to improper selection or damage, a ruptured hose can cause injury. If it bursts, a worker can be burned, cut,
injected or may slip and fall.
4. COUPLING-BLOW OFF: If the assembly is not properly made or installed, the coupling could come off and hit or spray a worker,
possibly resulting in serious injury. Never operate machine without guards.

FLAMMABILITY
With the exception of those comprised primarily of water, all hydraulic fluid is flammable when exposed to the proper conditions (including many
“fire-resistant” hydraulic fluids).
Leaking pressurized hydraulic fluids may develop a mist or fine spray that can flash or explode upon contact with a cause of ignition. These
explosions can be very severe and could result in serious injury or death.
Precautions should be taken to eliminate all ignition sources from contact with escaping fluids, sprays or mists resulting from hydraulic failures.
Sources of ignition could be electrical discharges (sparks), open flames, extremely high temperatures, sparks caused by metal-to-metal contact,
etc.
HYDRAULIC FLUID
Only use Texaco Rando 46 Hydraulic Oil or Compatible Fluid like IS032. Non-compatible fluids could cause damage to unit or serious injury.
USE CARBON MONOXIDE DETECTOR WHEN OPERATING MACHINE
Included with the 5625 are a 75007 lapel CO Monitor and a 75008 Clip. it is recommended that the operator and anyone in the working vicinity
wear the detector. Failure to do so could cause bodily injury and/or death. The use of detectors helps to verify if work area is safe from Carbon
Monoxide poisoning. The detector has an adhesive strip on the back for mounting or can be worn with the included clip. It can detect as little as
100ppm (part per million) carbon monoxide gas at approximate relative humidity range of 33% to 50%. if the humidity is very high it can detect
concentrations as low as 20ppm. the presence of CO will change the impregnated silica color change from red to red/brown and then to gray/
black as the concentration levels increase. once the detector is exposed to fresh air, it will return back to red. Shelf life in an unopened pack
is approximately two to three years (expiration date is visible through unopened package on the back). Once opened it should be replaced
approximately every ninety days. Write date opened in provided area on the front of the detector. read further user directions on the back of the
detector.
SAFETY SWITCH
The 5625 Propane Ride-On has been equipped with a safety switch under the seat, which requires the operator to be seated before the 5625
can be operated. Do not attempt the start-up procedure with out being seated on the machine.
BATTERY
• Contact with electrolytic acid can cause skin irritation and damage clothing. Wear a protective apron, gloves and goggles when working
with battery. Have plenty of fresh water and soap nearby in case battery acid contacts your skin, clothing, or eyes.
• Remove personal metal items such as bracelets, rings, necklaces, and watches when working with battery. A battery can produce a short
circuit current sufficient enough to weld metal objects, causing severe burns.
• Never smoke or allow a spark or flame in the vicinity of the battery. Caution must be taken to reduce the risk of dropping metal tools onto
the battery. A spark or short circuit may result in an explosion.
FIRST AID
Immediately flush eyes with cold, fresh water for a minimum of 10 minutes if electrolytic acid comes in contact with eyes. Seek professional
medical attention.
VENTILATION
Blocking louvers or air flow perforations of convection or fan cooled battery chargers and/or machine will result in damage to the unit. When
installing the unit leave space for air to flow freely through the intake and discharge louvers and/or perforations.
CAUTION: NEVER USE YOUR HANDS TO CHECK FOR LEAKS OVER HOSE OR HYDRAULIC CONNECTIONS. USE A PIECE OF CARD-
BOARD TO LOCATE A PRESSURIZED LEAK. FOR LOW PRESSURE LEAKS (DRIPS), USE A RAG TO CLEAN THE AREA AND DETERMINE
WHERE THE LEAK ORIGINATES.

GASES, DUST, STEAM, SMOKE
Do not weld, flame cut or perform grinding work on the 5625 Propane Ride-On without written authorization from the manufacturer. The danger
of fire or explosion exists when work of this nature is done. Begin maintenance work only when the machine is in Shut Down Mode (turned off).
SAFETY PRECAUTIONS (OPERATOR/PERSONNEL TRAINING)
Operating and maintenance personnel must verify availability of appropriate fire protection equipment, be properly trained in the use of the
equipment and know how to contact the Fire Department or Emergency Medical Service if needed.
SAFETY PRECAUTIONS
• Only qualified, trained personnel should operate this unit.
• Loose or damaged parts should be replaced immediately. Failure to do so could cause equipment damage or serious injury.
• Switches and levers should be inspected.
• Turn ignition key to Off position prior to performing maintenance on scraper.
• Motor and switches should be completely enclosed at all times with no exposed wiring.
• Disconnect negative lead from ignition battery before servicing. Failure to do so can cause damage to electrical system and/or electrical
shock.
• Only use National components. Failure to do so could cause damage or serious injury.
• Always be aware of support personnel and their proximity when in operation. Block off work area.
• Support personnel should never stand next to machine, in front of or behind machine while machine is running. Failure to do so could
cause serious bodily injury or death.
• Manual should be kept with machine in supplied holder for access by operator at all times.
• Always wear eye and hearing protection when running machine.
• Never defeat switches or guards.
• Remove blade when machine is not in use and/or lower cutting head to floor. Failure to do so could cause serious bodily injury.
• Wear gloves when changing blades. Always shut machine off when changing blades.
• Turn propane valve off before servicing scraper.
BEFORE CARRYING OUT MAINTENANCE OR REPAIR WORK:
• Let the engine and the exhaust system, cool down.
• Remove all traces of oil, combustible fuel or cleaning fluids from the scraper, its connections and fittings in particular.
• Do not use any aggressive cleaning products.
• Be sure that all cleaning rags are fiber free.
• Retighten all loose fittings found during maintenance and repair work.

Machine Operation
FIG. A
LOADING/UNLOADING
• Always remove blade and cutting head when machine is being moved or trans-
ported
• Cutting head and slide plate can be removed to make the machine more compact.
• NEVER leave machine unattended on an incline.
• Removing added weights help to make the machine easier and safer to move in
and out of a vehicle.
DOCK HEIGHTS
It is best to load or unload the machine from a level/equal dock height (a van from a van
dock height, a truck/semi from a regular dock height).
POWER-GATE
A power-gate can be used when the dock height is not available. Make sure gate is
properly rated for 2300 lb. Make certain the machine is secure so it does not roll off the
power-gate. To better secure machine, raise machine onto the lowered cutting head, rais-
ing machine off the caster. Tie machine down, chock wheels.
RAMPS
To be safe, the ramp needs to be long enough to accommodate the machine being load-
ed/unloaded. Remove added weight. Make sure ramp is secured. Do not have at a steep
incline. The use of a power winch or hand come-a-long is much safer. For a van, the
ramp should be 12 to 18 feet in length depending on the depth of the incline. For truck
height taller than a van, longer ramps will be needed. See OSHA guidelines. It is not
recommended to drive the machine on a ramp. Make sure ramp is secure and has good
contact before using. Failure to do so could cause ramp to fall away from the vehicle.
NOTE:SEE CORRECT AND SAFE OPERATING ANGLES AND CENTER OF GRAVITY ON PAGE 11.
FORKLIFT CUPS
There are two forklift cups mounted under the front of the machine (See Figure C).
Slide fork lift forks through forklift cups. Slide forks all the way back to touch the rear tire
(See Figure D). Before lifting machine, secure machine to fork lift with heavy 3000 lb. or
heavier rope or chain. Tilt forks back to lift machine (See Figure E).
WINCHES
Winches should be used for safety when loading or unloading with ramps. 2000 lb winch
minimum.
TRANSPORTING
Secure machine down with ratchet straps when transporting the machine. Chock wheels
to keep machine from rolling, hydraulic levers should not be locked in the forward or
backward position. Hydraulic levers should be straight up in the “neutral” position. This
helps to lock drive wheels. Lift machine off swivel caster by lowering cutting head for
better stabilization. Proper securing straps need to be rated at least twice the weight of
the machine.

WARNING: MACHINE HAS A SWIVEL FRONT CASTER. NEVER SIDE HILL (SEE
FIGURE A). THE MACHINE ON A INCLINE WITHOUT POWER, THE FRONT CASTER
WILL CAUSE MACHINE TO SWING TO THE LOWEST POINT. IF IT IS NECESSARY
TO RUN MACHINE ON AN INCLINE, RUN MACHINE ON CUTTING HEAD. PLACE
AT LEAST A 8’’ CUTTING HEAD IN MACHINE. TO KEEP FROM DAMAGING FLOOR, CLAMP A
PIECE OF CARPET INTO CUTTING HEAD TO SLIDE ON THE FLOOR. THIS WILL GIVE POSITIVE
CONTACT WITH THE FLOOR WHEN POWER IS DISENGAGED FROM THE WHEELS.
Caution Do Not “Side Hill”
Caution: Machine is back heavy, do
not run on steep incline. This could
cause the machine to tip over.

WHEEL CHOCKS
Wheel chocks will help to secure the machine but DO NOT use wheel chocks alone to
secure the machine.
CENTER OF GRAVITY
Be aware of your surroundings and machines operating angles. When changing from a
low slide plate to a high slide plate setting or a low cutting head angle to a high cutting
head angle, the operating “attitude” of the machine changes. When a floor surface is
not level (ramps, inclines, large amounts of debris which would lift the drive wheel of
the machine, etc.), the center of gravity changes (See Figure F, G & H). Too much of an
angle could make the machine unsafe (a cause for tip-over). Do Not run the machine in
unsafe environments.
JOB SITE MOVEMENT
• Always remove blade and cutting head when machine is being moved or trans-
ported
• Cutting head and slide plate can be removed to make the machine more compact.
• NEVER leave machine unattended on an incline.
• Removing added weights help to make the machine easier to move.
TAPING WHEELS
Taping the wheels with a wide masking tape helps to prevent damage and dirt to floors
during move-in and move-out.
FRONT WHEEL ASSEMBLY (FIGURE J)
The Front Wheel Assembly (#5110-100) is included and very helpful when moving the
machine around on a job-site or loading the machine that is not on a pallet. It allows ma-
chine stability and safe transportation over most surfaces. It is easy and quick to attach
or detach. Raise slide plate so the bottom of the slide plate is higher or even with the
bottom of the guide channels. Raise cylinder, insert Front Wheel Assembly into cutting
head. Secure with securing pin.2

WARNING: PROTECT OTHERS IN WORK AREA. PROVIDE BARRIERS OR
SHIELDS AS NEEDED TO PROTECT OTHERS FROM DEBRIS AND MACHINE
OPERATION. OPERATOR SHOULD BE AWARE OF WHO IS AROUND THEM AND
THEIR PROXIMITY.

Machine Operation
FIG. K
TO MOVE MACHINE WITHOUT POWER (PUSHING MACHINE)
Forward: To move the machine forward, levers need to be pushed forward. To lock
levers in place, connect a bungee-strap from each lever (pushing levers forward), pulling
straps down to and connecting to the front plate (See Figure K). Never leave machine
unattended with strap holding levers open.
Backward: To move machine backward, levers need to be pulled backwards. To lock
levers in place, connect a bungee-strap from each lever (pushing levers backward), Pull-
ing straps to the back of the machine and connecting behind the seat or the rear of the
machine (See Figure L). Never leave machine unattended with strap holding levers open.
MOVING MACHINE ON CASTER
Moving a “weighted” machine only on the front caster and not on the cutting head or the
Front Wheel Assembly can seem to make the machine turn sluggish. It might turn hard
to the right or the left. This is normal.
WHEEL SIZE
The 18’’ wheel comes standard on the machine. This wheel will work on all job types of
application and heavy debris build-up (VCT, ceramic etc.). It also works best for slippery/
slimy residue, ie. double stick.
Keep wheels clean and free of debris, make sure it can move freely. Clean as needed.
Inspect before each use.
To change wheels, see Wheel Changing on page 26.
FIG. L
Fax: [phone] [email protected]12
WARNING: ALWAYS REMOVE STRAPS BEFORE STARTING MOTORS.
FAILURE TO DO SO WILL MAKE MACHINE MOVE AND MAY CAUSE PROPERTY
DAMAGE AND/OR BODILY INJURY.
WARNING: WHEN DOING MAINTENANCE OR CHANGING A WHEEL, MAKE
SURE MACHINE IS SUPPORTED PROPERLY OR SERIOUS INJURY COULD
OCCUR.

• Start machine.
• Adjust throttle to desired RPM by pulling up on the throttle control.
• When at desired RPM, turn throttle friction knob counter-clockwise to hold in posi-
tion.
HYDRAULIC LEVERS (FIGURE Q)
The hydraulic levers steer the machine. They are feathered spool valves. For smooth
even movement, always move levers slowly. Fast movement on control levers will result
in jerky, uneven movement.
• Move levers slowly.
• Both levers forward ↑↑ move the machine forward.
• Both levers backward ↓↓ move the machine backward.
• The left lever forward and the right lever backward ↑↓ turn the machine quickly
to the right.
• The left lever backward and the right lever forward ↓↑ turn the machine quickly
to the left.
• Only using the left or right lever forward ↑, turns the machine slowly to the right
or left.
• Only using the left or right lever backwards ↓, turns the machine slowly to the left
or right.
• Correcting direction while moving forward is accomplished by slightly reducing
pressure on one lever or the other while moving.
• The center position on levers causes wheels to lock-up.
• Always chock wheels and tie down machine when transporting.

CARBON MONOXIDE DETECTOR (FIGURE Z)
Included with the 5625 are a 75007 Lapel CO Monitor and a 75008 Clip. It is recom-
mended that the operator and anyone in the working vicinity wear the detector. Failure to
do so could cause bodily injury and/or death. The use of detectors helps to verify if work
area is safe from Carbon Monoxide poisoning. The detector has an adhesive strip on the
back for mounting or can be worn with the included clip. It can detect as little as 100ppm
(part per million) carbon monoxide gas at approximate relative humidity range of 33 to
50%. If the humidity is very high it can detect concentrations as low as 20ppm. The pres-
ence of CO will change the impregnated silica color change from red to red/brown and

CUTTING HEAD & BLADES
DIALING IN THE MACHINE
Dialing in the machine is matching the correct cutting head, blade size, blade angle and
added weight to the machine to make the material removal as easy as possible. For
every material being removed, there is an optimum blade width, thickness, sharpness,
angle and bevel (bevel up or bevel down).
SAVING TIME WITH EXTRA CUTTING HEADS
The machine is supplied with one cutting head. Having additional cutting heads will save
time on the job. Insert blades into the extra cutting heads before starting a job. When
the blade is dull, instead of taking the time to replace it or sharpen it on the job, take out
the cutting head and replace it with another. Or when a different type or size of blade is
needed, you have them ready to use.
ADJUSTING THE DUAL LIFT SLIDE PLATE AND CUTTING HEAD
• For safety prior to adjusting the dual lift hydraulic slide plate make sure the channel
guide is free of any debris and the machine is safely positioned on a flat surface.
• Be properly seated in the operator’s seat.
• Twist the Red Emergency Stop switch located on the right side of the operator, the
spring-loaded switch will pop up when twisted.
• Push the Green ‘ON’ button to start the machine.
• Adjacent to the left hand steering lever is a straight and narrow handle rod, this
handle rod raises and lowers the front cylinder and is referred to as the ‘cutting
head lever’. To set the height of the hydraulic slide plate start by first adjusting the
angle or pitch of the cutting head holder.
• Pull back on the cutting head lever and raise the cutting head holder to an angle
higher than the bottom of the slide plate.
• Using the lever adjacent to the right hand steering lever raises and lowers the
hydraulic slide plate and is referred to as the ‘slide plate lever’. To lower the slide
plate the operator must push forward on the slide plate lever. Reversely, to raise
the slide plate the operator must pull back on the slide plate lever.
While the hydraulic slide plate can be adjusted to multiple positions there are two basic
slide plate settings.
• Low Setting: the hydraulic slide plate is positioned 1” off the floor. This setting is
most commonly used during initial scraping or removal applications; such as car-
pet, VCT, ceramic tile and wood flooring. (Note: The “low” setting on older model
hydraulic slide plates may stop the plate within one to two inches of the floors
surface.)
• High Setting: the hydraulic slide plate is positioned 6” off the floor or in most cases
flush with the bottom of the slide plate channel guide. This setting is most often
used for re-scraping glues, mastics, thin sets and soft coating.
SHEAR POINT
The shear point is the point where material to be removed will cut cleanly from the floor. If
the blade is too wide, too dull or too steep, the shear point is lost.
WEIGHT VS. SHARPNESS
The most common way to compensate for a dull blade is to add more weight and raise
the blade angle. Weight allows dull blades to be used to a point. Weight also causes
blades to dull and break easier. Blades of any thickness tend to catch cracks and expan-
sion joints and will bend or break the blade if set at a high angle. For best results, run a
small ditching blade at a low angle to identify as many cracks and joints as possible. If
blades are breaking, you are misunderstanding the conditions.

Low Setting: Slide plate 1/4” to 1/2” off the floor. The
lower the better. This is for normal removal of almost
everything.
High Setting: Slide plate is 6” off the floor. This is
for re-scraping glue and some thin-soft coatings.
Caution: Pinch point.

STEEP CUTTING HEAD ANGLE
A steep angle is only used for re-scraping. The slide plate has to be raised so the bottom
of the slide plate is higher or even with the bottom of the guide channels (See Figure
DD). Not raising the slide plate when operating the machine at a steep angle will cause
the machine to jump and buck. It does not give the operator a clear vision of the cutting
head and it raises the machine to operate at a unsafe operating height (See Figure EE).
Failure to raise the slide plate could cause machine damage and/or bodily injury.
SWIVEL HEAD
The swivel head keeps the blade in contact with the floor even when the floor is uneven.
When using a flat blade, by swiveling the head over 180° allows another sharp edge on
the blade without having to replace the blade.
CUTTING HEAD INSERTION
With machine off, insert desired cutting head into cutting head holder. Secure with cutting
head clip.
SHANK BLADE INSERTION
Shank blades do not require a cutting head. Insert desired shank blade into cutting head
holder. Secure with cutting head clip.
BLADE SETTING
• Dull blades greatly reduce cutting ability. Re-sharpen or replace as needed.
• Proper blade size and placement, depending on material and sub-floor type, af-
fects performance.
• The harder a job comes up, for best results, use a smaller blade.
• Start with a narrow blade, then increase blade size to optimize cutting pass. Nar-
rower blades work easier than wider blades and usually clean the floor better.
Wider is not always better or faster.
• Normally bevel on blade is up for concrete. Bevel down for wood and shoe blades
for soft sub-floors.
• KEEP BLADES SHARP.
• Dull blades greatly affect the performance of the machine and reduce cutting ability,
resharpen or replace as needed.
• Keep your work area clean and clear of debris.
• After you have removed a portion of material, remove it out of the way. This will give
the machine maximum performance and help to keep the work area safe.
• Always wear gloves when handling blades.
• Everyone in work area should wear eye protection.
SELF-SCORING BLADES
Instead of pre-scoring a job, for soft goods (carpet, vinyl, linoleum, membrane) the self-
scoring blades automatically do the scoring.

BLADE INSERTION OR BLADE CHANGING
Using a 3/4’’ socket wrench, loosen bolts on cutting head. Quantity of bolts will very de-
pending upon cutting head size. Insert blade into the cutting head to back of notch (See
Figure FF). Tighten firmly.
Note: A cordless 3/8’’ drive impact wrench will speed up this process especially out on
the job.
• Sharp blades are imperative for good performance.
• Always wear gloves when handling blades.
CERAMIC SET-UP
The slide plate should be adjusted to a low setting (1”) on inch off the floor. Use a Shank
Blade or a Shank Blade with a carbide tip.
WOOD SET-UP (FIGURE DD)
The slide plate should be adjusted to a low setting (1”) one inch off the floor. Use Shank
Blades, Shank Blades with carbide tips or a 6”or 8” Cutting Head with Shoe Blades, Bent
Shoe Blades or Heavy Duty Blades. Note: Run machine 45° to the grain of the wood.
SECONDARY BACKING CARPET SET-UP
The slide plate should be adjusted to a low setting (1”) one inch off the floor. Use a Cut-
ting head from 10” to 27” with Heavy Duty Blades or a Cutting Head from 10” to 14” with
a Self-Scoring Blade.
FOAM BACK CARPET SET-UP
The slide plate should be adjusted to a low setting (1”) one inch off the floor. Use Cutting
Heads from 10” to 14” with Self-Scoring Blades. If it is not stuck tight, use a Cutting Head
from 14” to 27” with a Standard Blade.
DOUBLE STICK CARPET SET-UP
The slide plate should be adjusted to a low setting (1”) one inch off the floor. It is best to
test to see which is the easiest way to remove double stick. Start with a Cutting Head
from 10” to 14” with Self-Scoring Blades (Figure HH). If self-scoring blades do not work,
score thru the carpet (Figure II) the width of the blade (Standard Blade) and scrape up. In
some cases, carpet might pull off the pad and then scrape up the pad separately. Usually
leaving carpet connected to the pad works the best. Sharp blades are necessary for
proper operation.
Note: When removing carpet from over VCT Tile and the tile needs to be saved, run the
machine at a 45° angle over the tile. This should help to save the tile.

VCT TILE SET-UP
The slide plate should be adjusted to a low setting (1”) one inch off the floor. If goods come up easily, change to a larger Cutting Head. If goods
come up harder, use a Cutting Head from 6” to 8” with a Premium High Tempered Blade (.062) to match cutting head size. Sometimes a .094
blade may work better. If goods remove easily, a Tile Box #7074 can be used. A tile box also works for wind rowing, assists for a fast clean-up
and collection of tile debris for quick removal.
RUBBER TILE SET-UP
The slide plate should be adjusted to a low setting (1”) one inch off the floor. Use a Cutting Head from 6” to 14” with self-scoring blades or use
ditching method with a flat blade.
RE-SCRAPING SET-UP
Slide plate should be set high, 6’’ to 8’’ off the floor. Use a Cutting Head from 8” to 27” with Scraper Blades to match cutting head size. A 15”
scrapper blade would use a 14” Cutting Head. Razor Blades are faster but a Cutting Head from 8” to 14” can be used with a Standard Blade.
Flip head regularly.
THIN COATING SET-UP
Slide plate could be set high, 6’’ to 8’’ or low 1” off the floor. Test to see which works best. Use a Cutting Head from 8” to 27” with Razor Blades
to match cutting head size.
WORKING OVER CONCRETE
Blade should be bevel up when working over concrete. Pretty much anything over concrete works. Try different set-ups to see which works
best. If goods come up difficult, the slide plate should be at a low setting, 1” off the floor. Use a smaller size blade. If goods come up easily, a
wider blade can be used.
WORKING OVER WOOD
A heavy machine cannot be used on wood subfloors or raised panel computer floors. Keep machine light, remove all weights. A weighted
machine could break through the floor. The slide plate should be adjusted to a low setting (1”) on inch off the floor. Blades should be as flat of an
angle as possible. Use a “shoe blade”, Extra Heavy Duty Blade (these blades have a bend to them) or a regular blade, bevel up. When using a
regular blade, bending up the corners of the blade will help from the blade digging into the floor. Sometimes a shank blade or a shank blade with
a carbide tip will work. Allow blade to shear material from the floor. The trick on wood floors is to run the blade flat. Approach should be at a 45°
angle to the board. This keeps from digging into the board and hanging up at the seams.
WORKING OVER SOFT SUB-FLOOR
The slide plate should be adjusted to a low setting (1”) one inch off the floor. Blades should be as flat of an angle as possible. Use a “shoe
blade”, Extra Heavy Duty Blade (these blades have a bend to them) or a regular blade, bevel up. When using a regular blade, bending up the
corners of the blade will help from the blade digging into the floor. Sometimes a shank blade or a shank blade with a carbide tip will work.
CAUTION: BLADES ARE SHARP, USE EXTREME CAUTION.
CAUTION: NEVER CHANGE CUTTING HEAD OR SERVICE BLADES WHILE MACHINE IS RUNNING.
WARNING: DISARM MACHINE WHEN MACHINE IS NOT IN USE. REMOVE THE CUTTING HEAD OR DROP CUTTING HEAD TO THE
FLOOR. FAILURE TO DO SO COULD CAUSE SEVERE BODILY INJURY.

DITCHING
CROSS ROOM DITCHING
When removing hard to remove ceramic, Vct or vat, cross-room ditching will help to make the removal easier. Using a blade 2” to 6” in width,
make ditches 1’ to 2’ apart in the same direction the machine will be removing the goods (See Figure HH). This “relieves” the pressure holding
the tiles together. If ditching helps and the goods are coming up easy, try using a wider blade to ditch with.
CHECKER BOARD DITCHING
To make carpet removal and debris cleanup easier, checker board ditching is very helpful. Using as wide of a self-scoring blade as possible,
make ditches 4’ to 6’ apart crossways from the way the machine will be removing the goods (See Figure II). Running the machine crossways
from the ditches will make smaller pieces of debris to be hauled away. Instead of large gummy rolls of carpet, there are small squares that can
be rolled, palletized, put on a dolly or folded with the sticky side in. This makes removing the debris easier and reduces the amount of debris.
BLADE SHARPENING
Dull blades greatly reduce cutting ability. Re-sharpen or replace as needed. In use, blades develop a back-bevel (See Figure JJ). When re-
sharpening, blade will not be truly sharp until all back-bevel is gone.
Note: Thinner blades are easier to sharpen, but they also break easier.
• Always wear gloves and safety glasses.
• Grind blade using a 4” diameter disk with 120 or finer grit. Be careful not to catch disk on edge or corner of blade.
• Pass grinder along blade edge starting on one end and continuing in one direction being careful to hold grinder at proper angle of blade.
Grind until sharp.
• While using a high quality fine tooth hand file, follow the same procedure as above.
• Blades are sharp. Use extreme caution.
• Have plenty of sharp blades on each job so on-the-job blade sharpening is eliminated.
• It is best to re-sharpen dull blades on proper bench or belt grinder in the shop, so the blades are ready for the next job.
SELF-SCORING BLADE SHARPENING
It is important to keep the “wings” on a self-scoring blade sharp (See Figure KK). Use a file on the “wing” edge. Sharpen the flat part of the
blade, the same way as described above.
CARBIDE TIPPED BLADE SHARPENING
To sharpen carbide tipped blades, a carbide grinding wheel is necessary, ie: silicon carbide or green wheel.
