OWNER / OPERATOR MANUAL RUNNING FLOOR II®DX / DXE
1.0 Safety
1.1 General Safety
1.1.1 Intended Function and Expected Use:
1.1.1.1. The KEITH®RUNNING FLOOR II® DX/DX-Europe system is a reciprocating slat
conveyor primarily intended to load, hold, or unload bulk materials. It can also handle
unit loads such as pallets by using special handling techniques and possibly additional
safety controls. The system is supplied as a kit primarily intended for installation into
mobile trailers or truck bodies. The oor is often loaded through an open trailer top
or through the rear doors. The oor typically discharges material out the rear door. It
is hydraulically actuated, powered by a pump mounted either to a PTO or an electric
motor. The basic system is controlled by mechanically-actuated valves, but has the
option for electrically-actuated valves. The system is compatible with options and
accessories to improve performance. For example, it can be electrically controlled
by hardwired switches or a wireless remote. A CleenSweep® device can improve
clean out. Floor slat styles are selected based on the materials to be conveyed. The
standard system handles a wide array of materials in a non-hazardous, non-explosive
environment. Special modications may be required for special environments like food-
grade applications or explosive conditions.
1.1.2 Improper Use
1.1.2.1. This equipment has been manufactured in accordance with state-of-the-art technology
and the acknowledged safety regulations. Nevertheless, dangerous situations could
arise from improper use, which could endanger life and limbs of personnel and cause
severe damage to the equipment and other assets. This equipment may only be used
for its intended purpose. It may only be operated in impeccable technical condition and
in accordance with the proper use and this user manual. Problems, which could affect
safety, must be resolved immediately. The manufacturer is not liable for any damage
caused by improper use or arbitrary modications. The installation, commissioning,
operation, and maintenance instructions must be followed as outlined in this manual.
1.1.2.2. Personnel must not enter the danger zone(s) when the system is enabled. Specically,
nobody should be inside, under, or behind the trailer in the unloading zone during
operation. Additionally, no one should be in a full or lling trailer. Lock-out and tag-out
procedures must be followed before accessing the drive area.
1.1.2.3. The maximum load capacity must not be exceeded. (See Specications section)
1.1.2.4. The hydraulic power source must not exceed the pressure and ow ratings. Install a
relief valve to ensure the maximum pressure is not exceeded.
1.1.2.5. Control circuitry must not be altered or bypassed.
1.1.2.6. Safeguards must not be altered or bypassed.
1.1.2.7. The oor structure must not be altered.
1.1.2.8. The oor should not be used to handle any material other than specied.
1.1.2.9. The user and system designer must understand the characteristics and safe handling
requirements of the material that is being conveyed.

2 DOC06179 Rev. B
OWNER / OPERATOR MANUAL RUNNING FLOOR II®DX / DXE
1.1.2.10. Bulk materials are by nature unstable and owable. Avoid burial by avoiding contact with
the material.
1.1.3 Training
1.1.3.1. Operators must read and understand this manual before operating or maintaining the
machine. Only qualied, trained personnel may execute commissioning, operation, and
maintenance of the system.
1.1.4 Personal Protective Equipment
1.1.4.1. Always wear protective equipment appropriate for risks associated with each phase of
the system’s life, including transportation, installation, assembly, operation, inspection,
maintenance, and dismantling, disabling, and scrapping. As a minimum, this includes
the following personal protective equipment:
• Safety glasses
• Gloves
• Welding/grinding protection
• Thermal protection such as coats
• Protective/traction shoes
• Helmets
• Hearing Protection
1.1.5 Airborne Noise Emission
1.1.5.1. There is not a dened workstation; sound pressure levels emitted by the WALKING
FLOOR
® modules were measured at a height of 1.6 meters from the oor surface and
a distance of 1 meter from the surface of the WALKING FLOOR
®system at the drive
area.
• The A-weighted emission sound pressure level = 74.8 dB.
• The peak C-weighted instantaneous emission sound pressure level = below 63 Pa.
1.1.5.2. Slower oor speeds result in less noise.
1.1.6 Temperature
1.1.6.1. Operation of the system generates heat in the hydraulic oil. Hot oil can damage the
internal seals, resulting in a failure to operate.
1.1.6.2. Overheated oil can degrade rapidly. Hot oil and the resulting hot surfaces can cause
burns. Do not allow the oil temperature to exceed 140 °F [60 °C].
1.1.6.3. KEITH recommends some or all of the following temperature control measures
depending on the circumstances. High duty cycle systems and hot environments will
require more control measures.
• Maintain adequate oil level in the reservoir.
• Install a thermometer or sensor to monitor oil temperature.
• Install a cooler.
• Set a sensor to automatically shut down the system if oil temperature exceeds
140 °F [60 °C].

3 DOC06179 Rev. B
OWNER / OPERATOR MANUAL RUNNING FLOOR II®DX / DXE
1.1.7 Lighting
1.1.7.1. Do not use or service the system in an environment of insufcient light.
1.1.8 Movement Around the System
1.1.8.1. Hydraulic oil can be slippery. Clean up oil spills immediately.
1.1.9 Hydraulic Oil Safety
1.1.9.1. See the MSDS for the oil used in your system for further information about hydraulic oil
safety.
1.1.9.2. In an accident involving high pressure equipment, this product may be injected under
the skin. Such an accident may result in a small, sometimes bloodless, puncture wound.
However, due to the system’s driving force, material injected into a ngertip can be
deposited into the palm of the hand. Within 24 hours, there is usually a great deal of
swelling, discoloration, and intense throbbing pain. Immediate treatment at a surgical
emergency center is recommended.
1.1.9.3. Do not use high pressure systems in the vicinity of ames, sparks, and hot surfaces.
Use only in well ventilated areas.
1.1.9.4. Use only designated appropriate ll and drain ports for the oil.
1.2 Design / Installation Safety
1.2.1 Kit Components
1.2.1.1. The kit consists of a drive unit, ooring, and miscellaneous boxed parts. These modules
are intended to be anchored in a shipping frame or stacked at and braced with
dunnage for shipping and storage.
1.2.2 Installation
1.2.2.1. Use designated lifting points as provided.
1.2.2.2. Only use equipment with appropriate capacity ratings to lift and handle
components.
1.2.2.3. Use appropriate lifting procedures when handling loose or boxed components.
1.2.2.4. The oor must be installed far enough away from other equipment or xtures to prevent
the moving parts of the oor module from creating a crush or pinch hazard.
1.2.3 Danger Zones
1.2.3.1. The reciprocating action of the oor creates pinch and shear points by nature.
Specically, drive area cylinder, cross-drive, and slats approaching each other,
frame components, or walls. These and any other relevant exposed areas must be
guarded.
1.2.3.2. The oor must be incorporated into surroundings such that movement of the material
on the oor does not create crushing, burial, drawing in, or entrapment hazards. The
system must be designed to limit access to the material ow path.

4 DOC06179 Rev. B
OWNER / OPERATOR MANUAL RUNNING FLOOR II®DX / DXE
1.2.4 Electric Components and Installation
1.2.4.1. KEITH recommends connecting to earth ground (whenever possible).
1.2.4.2. Wiring must be connected consistent with local codes and regulations, including
electromagnetic interference regulations.
1.2.4.3. Adequate electric overcurrent protection must be provided.
1.2.5 Hydraulics
1.2.5.1. Hydraulic piping and components must be constructed of materials that are rated for
system pressures, and must be installed with best industry practices. Follow all pipe,
tubing, tting, and hose manufacturer installation and routing guidelines.
1.2.5.2. Hydraulic piping should be supported and isolated from vibration. Contact a KEITH
representative for recommendations on installation.
1.2.5.3. Place protective shrouds around the hydraulic tubing in any areas that may have
operators or people frequently nearby.
1.2.6 Controls
1.2.6.1. The control panel must be located such that it is easily accessible for all sizes and
capacities of people, and allows the operator to move freely (whenever applicable).
1.2.6.2. Control devices must be located outside of danger zones, such that any exposed
persons in danger zones are visible from the control station.
1.2.6.3. An acceptable means must be provided to monitor the status and movement of the
load.
1.2.6.4. The oor can generate enormous horizontal force which can destroy improperly
designed surroundings. The oor module must not be allowed to compact material
against an end wall or door, or end walls and doors must be designed to absorb these
forces.
1.2.6.5. Do not allow the oor to move material toward the front of the trailer when material is
contacting the front wall. KEITH recommends installing limit switches to prevent this. In
the absence of a sensor switch, the operator must be keenly aware of the load position,
and the control system must require the operator to hold the run signal in the on
position to continue running, such that releasing the run signal causes the oor to stop
(momentary signal).
1.2.6.6. Material compacted against closed doors can force the doors open dangerously fast
when the door latch is released. The impact can cause serious injury or death. Do not
allow the oor to run when the doors are closed. Do not open a door when it is possible
that material may be compacted against it. KEITH strongly recommends installing a
control interlock switch to prevent the oor from running when the door is closed. KEITH
also recommends a door latch that can be remotely actuated by someone away from
the door area unload zone.

2.2 General Wet Kit Specications
Oil: ISO-L-HM 46 hydraulic oil (As per ISO 11158).
PTO and
Pump: *
The PTO and Pump must be capable of producing a minimum ow rate of 5
gal/min at 3000 PSI [19 liters/min at 207 bar] for proper operation. KEITH
recommends a PTO and Pump capable of producing between 40 and 60 gal/min at
less than 3000 PSI [151-227 liters/min at less than 207 bar] for optimal operation.
NOTE: Pumps with built-in pressure relief valves are NOT recommended.
See the Wet Kit RUNNING FLOOR II® document available on the KEITH website
www.KeithWalkingFloor.com or contact a KEITH Manufacturing Co. representative
for specic recommendations on selecting a wet kit.
Do not exceed the maximum ow rate.
Do not exceed the maximum pressure.
Filter: Filter should be double element, 10 to 25 µm, on the return line.
(The lter element should be changed after the initial 6 hours of operation, then
every 6 months thereafter. This may vary with the operating environment).
Hydraulic
Reservoir:
Sized to desired ow rate. Should hold approximately 1 gallon of oil for every gallon
per minute you plan to pump, i.e. 40 gal/min = 40 gallon reservoir. Minimum 40
gallons [151 liters]
Suction Line: Suction hose from the reservoir tank to the pump should be no more than 5 ft [1.5 m]
in length and a minimum of 2 inch [51 mm] inside diameter.
KEITH recommends using SAE100R4 (This type of hose has a spiral wire to keep
