HYDRAULIC SAFETY TIPS
MAINTAINING A SAFE WORK ENVIRONMENT
Establishing a safe work environment around your hydraulic equipment is paramount to safe and effective machine operation. The easiest and
most effective way to avoid problems is to make sure coworkers understand equipment, know how to operate safely and recognize the danger
represented if handled carelessly. A few things to be aware of:
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 wiring check.
Unplug batteries and/or charger before servicing.
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 130º F, 55° C), shut off machine and allow to cool off.
PRESSURE
Our system runs at or below 3,000 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.
7www.nationalequipment.com Phone: [phone]
CAUTION: NEVER USE YOUR HANDS TO CHECK FOR LEAKS OVER HOSE OR HYDRAULIC CONNECTIONS. USE A PIECE OF
CARDBOARD TO LOCATE A PRESSURIZED LEAK. FOR LOW PRESSURE LEAKS (DRIPS), USE A RAG TO CLEAN THE AREA AND
DETERMINE WHERE THE LEAK ORIGINATES.

Safety

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 making 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.
SAFETY SWITCH
The 8000 Propane Powered Ride-On has been equipped with a safety switch under the seat, which requires the operator to be seated before
the 8000 can be operated. Do not attempt the start-up procedure with out being seated on the machine.
USE CARBON MONOXIDE DETECTOR WHEN OPERATING MACHINE
Included with the 8000 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.
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
utilizing the unit leave space for air to flow freely through the intake and discharge louvers and/or perforations.

WARNING: SILICA DUST WARNING SCRAPING/GRINDING/CUTTING/DRILLING OF MASONRY, CONCRETE, METAL AND OTHER
MATERIALS CAN GENERATE DUST, MISTS AND FUMES CONTAINING CHEMICALS KNOWN TO CAUSE SERIOUS FATAL INJURY OR ILL-
NESS, SUCH AS RESPIRATORY DISEASE, CANCER, BIRTH DEFECTS OR OTHER REPRODUCTIVE HARM. IF YOU ARE FAMILIAR WITH
THE RISKS ASSOCIATED WITH THE PARTICULAR MATERIAL BEING CUT, REVIEW THE MATERIAL SAFETY DATA SHEET
AND/OR CONSULT YOU EMPLOYER, THE MATERIAL MANUFACTURER/SUPPLIER, GOVERNMENTAL AGENCIES SUCH
AS OSHA AND NIOSH AND OTHER AUTHORITIES ON HAZARDOUS MATERIALS. CALIFORNIA AND SOME OTHER AU-
THORITIES, FOR INSTANCE, HAVE PUBLISHED LISTS OF SUBSTANCES KNOWN TO CAUSE CANCER, REPRODUCTIVE
TOXICITY, OR OTHER HARMFUL EFFECTS. CONTROL DUST, MIST AND FUMES AT THE SOURCE WHERE POSSIBLE. IN
THIS REGARD USE GOOD WORK PRACTICES AND FOLLOW THE RECOMMENDATIONS OF THE MANUFACTURER/SUP-
PLIER, OSHA/NIOSH, AND OCCUPATIONAL AND TRADE ASSOCIATIONS. WHEN THE HAZARDS FROM INHALATION OF
DUST, MISTS AND FUMES CANNOT BE ELIMINATED, THE OPERATOR AND ANY BYSTANDERS SHOULD ALWAYS WEAR
A RESPIRATOR APPROVED BY OSHA/MSHA FOR THE MATERIAL BEING CUT.

RISK OF EXPLOSIVE GASES
Chargers can ignite flammable materials and vapors. Do not use near fuels, grian, dust, solvents, or other flammables. Batteries generate ex-
plosive gases during normal operation. To reduce the risk of battery explosion it is important each time, before using the charger, you read this
manual a manufacturer of any equipment you intent to use in the vicinity of the batteries or battery charger. Review all cautionary markings.
GASES, DUST, STEAM, SMOKE
Do not weld, flame cut or perform grinding work on the 8000 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).

WARNING: VENTILATION IS REQUIRED IN CONFINED WORK ENVIRON-
MENTS. CARBON MONOXIDE IS A VERY TOXIC, COLORLESS AND ODOR-
LESS GAS. WHEN ENGINES OPERATE IN ENCLOSED SPACES, SUCH AS
WAREHOUSES, BUILDINGS UNDER CONSTRUCTION, OR TUNNELS, CARBON
MONOXIDE CAN ACCUMULATE QUICKLY AND REACH CONCENTRATIONS
THAT ARE DANGEROUS FOR HUMANS. IT CAUSES HEADACHES, DIZZINESS,
LETHARGY AND DEATH. CO IS USUALLY THE MAJOR CONCERN WHENEVER

Machine Operation
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 prop-
erly rated for 1590 kg (3500 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,
raising machine off the caster. Tie machine down, chock wheels.
RAMPS
To be safe, the ramp needs to be very long to accommodate the machine being loaded/
unloaded. Remove added weight. Make sure ramp is secured. Do not have at a steep in-
cline. The use of a power winch or hand come-a-long is much safer. For a van, the ramp
should be 3.6 to 5.5 m (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, connected with power, 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 15.
FORKLIFT CUPS
There are two forklift cups mounted under the front of the machine (See Figure L). Slide
fork lift forks through forklift cups. Slide forks all the way back to touch the rear tire (See
Figure M). Before lifting machine, secure machine to fork lift with heavy 1590 kg (3500 lb)
or heavier rope or chain. Tilt forks back to lift machine (See Figure N).
WINCHES
Winches should be used for safety when loading or unloading with ramps. 1590 kg (3500
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.
13
WARNING: MACHINE HAS A SWIVEL FRONT CASTER. NEVER SIDE HILL
(SEE FIGURE K). 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.

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 O, P & Q). 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.
LEAP FROGGING BOARDS
Leap frogging boards help to protect floors from damage. Use two or three ¼” luan or ply-
wood sheets, approximately 68.8 cm (27”) wide by 1.8 m (6’) long. Cover one side of the
board with a thin a carpet. With the carpet side to the floor, place a board in front of the
machine. Drive onto the board. Set the next board in front of the machine. As you drive
off one board, pick it up and set it in front of the machine.
FRONT WHEEL ASSEMBLY (FIGURE S)
The Front Wheel Assembly is an attachment that is 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.
NOTE: Make sure the plate is parallel with the floor so the caster swivels freely.

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 T). 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),
pulling straps to the back of the machine and connecting behind the seat or the rear of
the machine (See Figure U). 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 21’’ 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.
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.

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 (see re-scrape set up Page 19). 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 expansion joints and will bend or break the blade if set at a high an-
gle. 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.
CUTTING HEAD ANGLE
Set the cutting head angle to where the material comes up the easiest. The lowest is
usually the best.
ADJUSTING THE DUAL LIFT HYDRAULIC SLIDE PLATE
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.
To begin it is necessary to be properly seated in the operator’s seat.
Next, twist the Red Emergency Stop switch located to the right of the operator. The E-
Stop switch is spring loaded and will pop “Up” when twisted.
Push the green “On” button to start the machine.
To set the height of the hydraulic slide plate you must first adjust the angle or pitch of the
cutting head holder.
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 commonly referred to as the “cutting head
lever”.
Next pull back on the cutting head lever and raise the cutting head holder to an angle
higher than the bottom of the slide plate; then release the lever.
There is also a straight and narrow handle rod adjacent to the right hand steering lever.
This handle rod raises and lowers the hydraulic slide plate and is commonly referred to
as the “slide plate lever”.
To lower the slide plate the operator must push forward on the slide plate lever. Reverse-
ly, to raise the slide plate the operator must pull back on the slide plate lever.
While the hydraulic slide plate can be adjusted to many different positions, there are two
basic slide plate settings.
A “low” setting has the hydraulic slide plate positioned approximately one ince off the
floor. This setting is most commonly used during initial scraping or removal applications;
such as carpet, VCT, ceramic tile and wood flooring applications.
Note: The “low” setting on older model hydraulic slide plates may stop the plate within
one to two inches of the floors surface.

Low Setting: Slide plate 1” 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.

ADJUSTING THE DUAL LIFT HYDRAULIC SLIDE PLATE (CONT.)
A “high” setting has the hydraulic slide plate positioned six inches 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 coatings.
The operator may now install the cutting head attachment based on the type of scraping
application required.
Make sure to wear proper work gloves when installing or removing any cutting head
attachments.
With the machine off, slide the shaft off the cutting head attachment into the cutting head
holder and secure it to the holder with a cutting head clip.
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 X).
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 Y). 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.

FIG. Z
• 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 Z). 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
Slide plate should be set low, slide plate should be set to the lowest setting or approxi-
mately 2.5 cm (1”) off the floor. Use a Shank Blade or a Shank Blade with a carbide tip.
WOOD SET-UP
Slide plate should be set low, slide plate should be set to the lowest setting or approxi-
mately 2.5 cm (1”) off the floor. Use Shank Blades, Shank Blades with carbide tips or a
15.25 to 20.3 cm (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
Slide plate should be set low, slide plate should be set to the lowest setting or approxi-
mately 2.5 cm (1”) off the floor. Use a Cutting head from 25.4 to 68.6 cm (10” to 27”) with
Heavy Duty Blades or a Cutting Head from 25.4 to 35.5 cm (10” to 14”) with a Self-
Scoring Blade.
FOAM BACK CARPET SET-UP
Slide plate should be set low, slide plate should be set to the lowest setting or approxi-
mately 2.5 cm (1”) off the floor. Use Cutting Heads from 25.4 to 35.5 cm (10” to 14”) with
Self-Scoring Blades. If it is not stuck tight, use a Cutting Head from 35.5 to 68.6 cm (14”
to 27”) with a Standard Blade.

DOUBLE STICK CARPET SET-UP
Slide plate should be set low, slide plate should be set to the lowest setting or approximately 2.5 cm (1”) 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 25.4 to 35.5 cm (10” to 14”) with Self-Scoring Blades. If self-
scoring blades do not work, score thru the carpet 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.
VCT TILE SET-UP
Slide plate should be set low, slide plate should be set to the lowest setting or approximately 2.5 cm (1”) 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
Slide plate should be set low, slide plate should be set to the lowest setting or approximately 2.5 cm (1”) off the floor. Use a Cutting Head from
15.25 to 35.5 cm (6” to 14”) with self-scoring blades or use ditching method with a flat blade (see page 20).
RE-SCRAPING SET-UP
Slide plate should be set high, approx 15.25 cm (6’’) off the floor. Use a Cutting Head from 20.3 to 68.6 cm (8” to 27”) with Scraper Blades to
match cutting head size. A 38.1 cm (15”) scrapper blade would use a 35.5 cm (14”) Cutting Head. Razor Blades are faster but a Cutting Head
from 20.3 to 35.5 cm (8” to 14”) can be used with a Standard Blade. Flip head regularly.
THIN COATING SET-UP
Slide plate could be set to the low or high setting off the floor. Test to see which works best. Use a Cutting Head from 20.3 to 68.6 cm (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, slide plate should be at a low setting, slide plate should be set to the lowest setting or approximately 2.5 cm (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 ma-
chine could break through the floor. Slide plate should be set low, slide plate should be set to the lowest setting or approximately 2.5 cm (1”) 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 prevent the blade from 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
Slide plate should be set low, slide plate should be set to the lowest setting or approximately 2.5 cm (1”) 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 prevent the blade from digging into the floor. Sometimes a shank blade or a shank
blade with a carbide tip will work.
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 FILE.

Machine Operation
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 5 to 15.25 cm
(2” to 6”) in width, make ditches 30 to 60 cm (1’ to 2’) apart in the same direction the machine will be removing the goods (See Figure BB). 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 1.2 to 1.8 m (4’ to 6’) apart crossways from the way the machine will be removing the goods (See Figure CC). Running the ma-
chine 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
Always check for blade sharpness before using; because dull blades greatly reduce cutting effectiveness. Over time, the used blades will
develop a back bevel. While re-sharpening, blades will not recover entirely until the back bevel is completely leveled out. 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 these self-scoring blades sharp. Use a file on the 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.
