HYDRAULIC SAFETY
Maintaining a Safe Work Environment
Establishing a safe work environment in and around your hydraulic equipment is extremely important. The easiest and most effective way to
avoid problems is to make sure associates understand their equipment, know how to operate the machines safely, and recognize the dangers if
handled carelessly. A few things to be aware of are:
•Pressure: Hydraulic fluid under pressure is dangerous and can cause serious injury. 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:
▪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.
▪Leak: Keep fittings and hoses tight. Only check and service when not under pressure. Leaking hydraulic fluid is hazardous; in addition
to making workplace floors slippery and dangerous, it also contaminates the environment. Before cleaning an oil spill, always check
EPA, state, and local regulations.
▪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.
▪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: When ignited, some hydraulic fluids can cause fires and/or explode.With the exception of those comprised primarily of
water, all hydraulic fluid is flammable (including many “fire-resistant” hydraulic fluids) when exposed to the proper conditions. Leaking pres-
surized hydraulic fluids may develop a mist or fine spray that can flash or explode upon contact with a source 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.
•Mechanical: Hydraulic fluid creates movement, which means some equipment may move. Observe surroundings and equipment at all
times.
•Moisture: Do not use in wet or high moisture conditions.
•Electrical: Faulty wiring can be an electrical hazard. A regular preventive maintenance program should always include a wiring check. If
applicable, disconnect battery before serving.
•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 55°C), shut off machine and allow it to cool.
Hydraulic Fluid
Only use Texaco Rando 46 Hydraulic Oil or compatible fluid like ISO or AW #46 from a brand name manufacturer. Non-compatible fluids could
cause damage to unit or serious injury.
DANGER: DO NOT TOUCH A PRESSURIZED HYDRAULIC HOSE ASSEMBLY WITH ANY PART OF THE BODY. IF FLUID PUNCTURES
THE SKIN, EVEN IF NO PAIN IS FELT, A SERIOUS EMERGENCY EXISTS. OBTAIN MEDICAL ASSISTANCE IMMEDIATELY. FAILURE TO DO
SO COULD RESULT IN LOSS OF THE INJURED BODY PART OR DEATH.
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.

Safety
RECOMMENDED ELECTRICAL PRACTICES
Power Cord Sizing
All cords should be sized appropriately to reduce the risk of damage, fire or reduced performance. Reference the tables in this section for
recommended cord sizes.
How To Use This Table
1. Determine your supply voltage.
2. Determine the total length of your cord including any extension cords.
3. Determine the maximum amp draw for your machine.
4. Trace your voltage across the top of the table to the first length that is greater than or equal to your cord length.
5. Follow the column down to the first row that contains a maximum amp draw greater than or equal to yours.
6. This cell contains the minimum recommended wire size for your application.
Example
Application: Max Amps = 13A, Length = 60ft, Voltage = 120V
Solution: 60ft is between the 50ft and 75ft columns, so the larger of the two columns is chosen. Likewise, 13A is between the 12A and 14A
rows, so the larger of the two rows is chosen. 12 AWG (4mm2) is the minimum recommended wire size for this example.
CAUTION: ALWAYS FOLLOW APPLICABLE ELECTRICAL CODES, STANDARDS AND/OR REGULATIONS. CONSULT YOUR LOCAL
ELECTRICAL AUTHORITY OR A LICENSED ELECTRICIAN BEFORE ATTEMPTING TO MODIFY AN ELECTRICAL INSTALLATION. ENSURE
THAT CIRCUIT AND GROUND FAULT PROTECTION DEVICES AND ALL OTHER ELECTRICAL SAFETY EQUIPMENT ARE FUNCTIONING
PROPERLY.

PREPARING MACHINE FOR JOB
Blade Setting
Note: This machine is designed to remove soft good materials.
•Depending on material and sub-floor type, proper blade size and placement affect
performance.
•For harder jobs, 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 the blade is up for concrete (Figure 4); bevel down for wood
(Figure 5).
•Dull blades greatly affect the performance of the machine and reduce cutting ability.
Re-sharpen or replace blades as needed.
•Remove any nails or metal obstructions on wood/wood-like flooring prior to use to
avoid blade damage.
•Blades can be offset in cutting head for easier access to toe kicks or removal along
the wall (Figure 6).
•Sheet vinyl, solid vinyl, rubber tile, urethane, or PVC sheet roofing will need to be
scored for best removal results. It recommend to use a self-scoring blade.
•Self-scoring blades eliminate the need for pre-scoring material. Depending upon
the type of material being removed and the sharpness of the blade and scoring
wings, the self-scoring blades may make it harder to control the machine. Keep
scoring wings sharp at all times.
Blade Changing
1. Place a flat piece of wood under the front of the machine.
2. Use the supplied extended 7/32 “T” wrench (Domestic) or a 6 mm Hex wrench
(International) with at least a 3” (76 mm) extension to keep hand safely away from
the sharp edge of the blade. Loosen the two Allen headbolts.
3. Place blade into the cutting head and slide back until fully seated against the ma-
chined edge. If the blade is wider than the cutting head, center the blade to the
head. If the blade is smaller than the cutting head, the blade should be mounted in
the center of the cutting head during the first pass. After the first pass is made, the
blade can be offset in the head to allow the wheels to keep even contact with the
floor and provide easy access to the wall.
4. Tighten the bolts.

APPLICATION SETUP
VCT Tile
Never use a blade wider than the size of the tile being removed. If goods being removed
still do not come up clean or machine jumps on top of goods, reduce blade size until
proper blade size is found or use a smaller portion of the blade.
Pure Vinyl Rubber Tile
Goods will need to be scored every 25.4-30.5 cm for proper removal. Self- scoring blades
can be used with some materials. A 25.4 cm blade is recommended for this product, but
determine what size blade works best.
Direct-Glued Carpet
manufacturer recommends using a self-scoring blade. Normally 30.5-35.5 cm self-
scoring blades are used on direct-glued carpet, secondary-backed, unitary, double-
glued, vinyl foam, and urethane foam.
Concrete
When working on concrete slab, normal blade position is bevel up for best performance,
especially when cleaning adhesive. On occasion, bevel down gives better blade life. Test
each job for best performance.
Gypcrete and Soft-Poured Flooring
Requires blade bevel down to create a better wearing surface.

Operation
BLADE SHARPENING
Dull blades greatly reduce cutting ability. Re-sharpen or replace as needed. In use,
blades develop a back-bevel (Figure 8). 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 10 cm 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 direc-
tion, being careful to hold grinder at proper angle of blade. Grind until sharp.
•Using a good quality fine tooth hand file, use same procedure asabove.
•Blades are sharp. Use extreme caution.
•Have plenty of sharp blades on each job so on-the-job blade sharpening is elimi-
nated.
•It is best to sharpen dull blades on proper bench or belt grinder.
Self-Scoring Blades
It is important to keep the “wings” on a self-scoring blade sharp (Figure 9). Use a file on
the wing edge. Sharpen the flat part of the blade, the same way as described above.
