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 uid 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 uid 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 ttings and hoses tight. Only check and service when not under pressure. Leaking hydraulic uid is hazardous; in addition
to making workplace oors 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 uids can cause res and/or explode.With the exception of those comprised primarily of
water, all hydraulic uid is ammable (including many “re-resistant” hydraulic uids) when exposed to the proper conditions. Leaking pres-
surized hydraulic uids may develop a mist or ne spray that can ash 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 uids, sprays or mists resulting from hydraulic failures. Sources of ignition could be electrical discharges (sparks), open
ames, extremely high temperatures, sparks caused by metal -to -metal contact, etc.
• Mechanical: Hydraulic uid 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 uid like ISO or AW #46 from a brand name manufacturer. Non-compatible uids could
cause damage to unit or serious injury.
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.
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.

ELECTRICAL PRACTICES
Extension Cord Requirements
• Ensure the cord type is suitable for the application and location. If you are unsure about your cord type, consult a qualied electrical profes-
sional or electrician.
• FULLY INSERT plug into outlet.
• Do not use excessive force to make connections.
• Never unplug by pulling the cord from the outlet. Pull plug rather than cord to reduce the risk of damage.
• Regularly examine your extension cord and ensure it is in good electrical condition. Never use a damaged cord—either replace it or have
it repaired by a qualied person.
• Protect your extension cords from sharp objects, excessive heat and damp or wet areas. Keep the cord away from oil, cutting edges and
moving parts.
• Do not drive, drag or place objects over cord.
• Avoid overheating. Uncoil cord and do not cover it with any material.
• Avoid accidental starting. Be sure equipment is turned off before plugging in. Do not use equipment if the power switch does not turn the
equipment on and off.
• Make sure equipment is not running before disconnecting cord.
• Unplug equipment. When not in use and before changing accessories or performing maintenance, unplug the machine.
Extension Cord Selection
All cords should be sized appropriately to reduce the risk of damage, re or reduced performance. Reference the table below for cord sizes.
Note: These cord sizes are based on a <10% voltage loss, data from the U.S. National Electrical Code Tables 400.5(A) & 400.5(B) and typical
resistances for copper wire.

TRANSPORTATION
Attach/Remove Transport Wheels
Transport wheels help eliminate damage to the ooring and make moving the machine
easier. To attach transport wheels, complete the following steps:
1. Remove two outside blade cover bolts (Figure 1).
2. To ensure cutting head has enough clearance for front wheel assembly to t under,
tip machine back and block up the front (Figure 1.1).
3. Mount front wheel assembly over blade cover; re-place two outside blade cover
bolts (Figure 1.2).
4. Remove blocks.
Note: Do not leave machine in transport mode during transit without being secured.
To remove, reverse these steps.
Lifting Bail
The lifting bails make loading/unloading easier when when unable to use a ramp. Loca-
tion of lifting bails centers the balance of the machine, making it safe to pick up machine.
1. Place rope, hook system, or chain through eyelets located on top of machine.
2. Raise machine with a fork lift or winch.
3. Slowly lower to desired location.
Ramp Unloading
1. Put the wheels in “engage mode” (Figure 2).
2. Position ramp securely to back of vehicle; ensure there is good contact.
3. Position machine at the back of the truck, in line with the ramp.
4. Carefully move machine onto ramp, leaving the cutting head down (in contact with
ramp surface). Be cautious; machine is heavy.
5. Slowly back machine down ramp.
WHEEL MODES
Wheels engage and disengage for easier maneuverability. Wheels in the “engage mode”
are secured with axle pins (Figure 2), which engage the wheels so the machine can be
self-propelled.
When wheels are in the “disengage mode” (Figure 2.1), the machine can be moved freely
when not under power.
Disengaging Wheels
1. Lift ring outwards; slide pin up and off.
2. Repeat on second wheel.
Note: Keeping the axle pin facing straight up will make re-engaging easier.

1. Line up wheel hub hole and axle hole (Figure 3).
2. Insert pin and push ring over the hole so that it is parallel to the wheel.
3. Repeat on second wheel.
APPLICATION SETUP
VCT Tile
Never use a blade wider than the size of the tile being removed. If materials being
removed still do not come up clean or machine jumps on top of materials, reduce blade
size or use a smaller portion of the blade.
Pure Vinyl Rubber Tile
Materials will need to be scored down to 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 ap-
plication.
Direct-Glued Carpet
Manufacturer recommends using a self-scoring blade. Normally 15.2-35.6 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, a normal blade position is bevel up for best perfor-
mance, 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.
INSTALLING AND ADJUSTING SLIDE WEIGHTS
Installing Slide Weights
Orientate the slide weight with the long channel below the short channel. Install the long
channel over the heads of the two Allen bolts. Holding the slide weight in place, install the
hex bolt into the threaded hole aligned with the short channel. Tighten the hex bolt using
a 3/4” socket wrench to secure the weight to the side of the machine.
Adjusting Slide Weights
To adjust the slide weight forward or backward based on the job application, loosen the
hex bolt using a 3/4” socket wrench and gently slide the weight to the desired position.
After adjusting, retighten the hex bolt to secure the weight to the side of the machine.

FIG. 3
WARNING: ALWAYS ENSURE THE HEX BOLTS ARE TIGHT AND THE SLIDE
WEIGHTS ARE SECURE. UNSECURED WEIGHTS COULD SHIFT CAUSING
BODILY INJURY. USE CAUTION IF LOOSENING THE HEX BOLTS–IF BACKED
OUT TOO FAR, THE SLIDE WEIGHTS COULD DROP CAUSING BODILY INJURY.

PREPARING BLADES
Setting
Note: This machine is designed to remove soft good materials.
• Proper blade size and placement will affect performance, depending on the mate-
rial and sub-oor type.
• For difcult materials, use smaller blades.
• 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 oor better.
• Normally, bevel up is for concrete; bevel down is for wood.
• Keep blades sharp. Dull blades greatly affect the performance of the machine and
reduce cutting ability. Sharpen or replace blades as needed.
• Keep work area clean and clear of debris. After removing a portion of material,
move it out of the way.
• For wood or wood-like oors, pound down or remove any nails or metal obstruc-
tions to avoid blade damage.
• Blades can be offset in the cutting head for easier access to toe kicks or for removal
along the wall (Figure 5).
• Sheet vinyl, solid vinyl, rubber tile, urethane, or PVC sheet roong will need to be
scored for best removal results. Using a self-scoring blade is recommended.
FIG. 5
FIG. 4
CAUTION: BLADES ARE SHARP. USE EXTREME CAUTION WHEN
HANDLING. NEVER CHANGE CUTTING HEAD OR SERVICE BLADES WHILE
MACHINE IS RUNNING. ALWAYS WEAR GLOVES WHILE HANDLING BLADES.

FIG. 6.1
FIG. 6.2
• Self-scoring blades are available in a number of sizes; these 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. Block up the front of the machine (Figure 6) using a at piece of wood or something
similar.
2. Use the supplied extended 6 mm Hex wrench to keep hand safely away from the
blade. Loosen the ve hex drive bolts (Figure 6.1), it is not necessary to remove
them completely.
3. Place blade into the cutting head and slide back until fully seated against the ma-
chined edge (Figure 6.2).
Note: Do not insert blade all the way back to the bolts. Incorrect installation of
blade will cause insufcient clamping leading to premature blade wear and dam-
age.
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 rst pass. After the rst pass is made, the blade can be off-
set in the head to allow the wheels to keep even contact with the oor and provide
easy access to the wall.
4. Tighten the bolts.
Blade Sharpening
Always check for blade sharpness before using. Over time, the used blades will develop
a back bevel. While 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.
• Grind blade using a 10 cm diameter disk with 120 or ner grit. Be careful not to
catch disk on the edge or corner of the blade.
• Pass grinder along blade edge starting on one end and continuing in one direction
being careful to hold grinder at proper angle for the blade. Grind until sharp.
• While using a high quality ne tooth hand le, follow the same procedure as above.
• Have plenty of sharp blades on each job so that on-the-job blade sharpening is
eliminated.
• It is best to sharpen blades on a proper bench or belt grinder in the shop.
Sharpening Self-Scoring Blades (Figure 7): It is important to keep the “wings” on these
self-scoring blades sharp. Use a le on the edge; sharpen the at part of the blade as
described above.
Sharpening Carbide-Tipped Shanks: To sharpen carbide-tipped shanks, a carbide
grinding wheel is necessary (e.g. silicon carbide or green wheel).
