1.0 Safety
1.1 General Safety
1.1.1 Intended Function and Expected Use:
1.1.1.1. The KEITH®WALKING FLOOR®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 KEITH®WALKING FLOOR®Sweep System 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 utilizing state-of-the-art technology in accordance
with 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 a󰀨ect
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.
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.
1.1.2.10. Bulk materials are by nature unstable and owable. Avoid burial by avoiding contact with
the material.
1.1.3 Temperature
1.1.3.1. Operation of the system generates heat in the hydraulic oil. Hot oil can damage the
internal seals, resulting in a failure to operate.

iv DOC06820 Rev. A
SERVICE / REPAIR MANUAL RUNNING FLOOR II®DX
1.1.3.2. 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].
1.1.3.3. 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].
1.1.4 Hydraulic Oil Safety
1.1.4.1. See the Material Safety Data Sheet (MSDS) for the oil used in your system for further
information about hydraulic oil safety.
1.1.4.2. In an accident involving high pressure equipment, hydraulic oil 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.
1.1.4.3. Do not use high pressure systems in the vicinity of ames, sparks, and hot surfaces. Use
only in well ventilated areas.
1.1.4.4. Use only designated appropriate ll and drain ports for the oil.

3.4 Start Up
3.4.1 Before Initial Start-Up
• Read through the RUNNING FLOOR DX/DXE Owner/Operator Manual. If there is any confusion,
contact KEITH to resolve any concerns before operating this system (See 6.0 Contact Information
section).
• Ensure that the hydraulic reservoir has the recommended amount of oil as well as the correct type
of oil (See 2.2 Specications section or visit our website for additional details).
• Torque cylinder barrel clamp bolts and oor bolts. (See 4.3 Maintenance section for special values
and instructions.) Loose cylinder barrel clamp bolts and ooring bolts are the most common cause
of severe damage to the drive or ooring.
• Familiarize yourself with 4.2 Preventative Maintenance section of this manual. Following the
maintenance schedule will signicantly improve the life of the system.
3.4.2 After initial 6 working hours (rst week of operation)
• Visually inspect the system for hydraulic leaks. If any leaks are found, retighten ttings.
• Change oil lters. This will ensure that any contamination that was ushed out in the start-up will not
prematurely wear out your system.
• Torque cylinder barrel clamp bolts and oor bolts. (See 4.3 Maintenance section for special values
and instructions.) Loose cylinder barrel clamp bolts and ooring bolts are the most common cause
of severe damage to the drive or ooring. Any bolts that were loose should be checked weekly until
found to be tight.
3.5 Pre-Trip Checklist
9Inspect hoses and quick connectors for damage and contamination. Clean all dirt and water from
connectors before hooking up (if applicable).
9Inspect drive unit for leaking ttings or hoses, and visible damage.
9Open truck or trailer doors and inspect ooring for damage. Inspect ooring at the rear of the truck
or trailer for loose or bent slats that may have popped up.
9Hook up hydraulic connectors (if applicable). Operate the oor and inspect for leaks. Test the On/
O󰀨 for proper operation. Test the load/unload for proper operation.
9If problems are found, report them to the maintenance shop as soon as possible.
9Secure truck or trailer doors and proceed.
As the driver, you will see damage or operational problems before anyone else. Please report issues
and concerns as soon as possible.
WARNING: Observations may be made while system is operating for troubleshooting
purposes, but NEVER touch any moving part or attempt to make any adjustments to the system
with the Power Take O󰀨/Pumping system engaged or the WALKING FLOOR®unloader operating.
WARNING: Do not attempt to make adjustments or repairs without consulting with a trained
service technician from your company or KEITH (See 5.4 Technical Support section for contact
information.)

SERVICE / REPAIR MANUAL RUNNING FLOOR II®DX
3.6 Standard Operating Procedures
3.6.1 Manual Controls
DANGER: ALWAYS have doors fully open! NEVER, under any circumstances, engage the
WALKING FLOOR®unloader with the doors of the truck/trailer closed. Catastrophic failure to the
truck/trailer, as well as serious injury or death may occur.
DANGER: Use caution when opening doors. Material can become compacted against doors
and they can open violently causing serious injury or death.
DANGER: NEVER allow anyone to stand or move through the area where the load is being
discharged or go under truck/trailer body or enter truck/trailer while the system is operating.
Burial, loss of limb or life may occur.
WARNING: While unloading, NEVER leave truck and trailer unattended.
1. Set parking brake on the truck/trailer and follow the Pre-Trip Check List.
2. Inspect hydraulic hoses and quick connects for contamination or damage (if applicable), then
connect the oor to the truck wet kit.
3. If the load is covered with a tarp, remove and secure the tarp prior to engaging the oor.
4. Manually open truck/trailer rear door(s) fully and secure door(s) with provided chains or loop rings.
5. Place control valve handle (See gure below) in the required position for the desired direction of
material movement (Unload/Load).
6. Push ball valve handle in (See gure above) to the fully open (OFF) position. The oor will not
operate! Ball Valve handle is located between the pressure and return lines. NOTE: The ball valve
controls On/O󰀨 and is used as an emergency stop.
7. Engage PTO (Do NOT increase engine RPM’s from idle). This allows hydraulic oil to start owing
through the pump and warming up before engaging the oor (ideally to 80 °F [27 °C]).
8. Fully open hydraulic cover and/or hydraulic rear truck/trailer door(s) (if equipped).
9. Pull out the ball valve handle to the fully closed (ON) position. The oor will start to operate!
10. Increase truck engine RPM’s to predetermined setting to achieve desired ow rate from the wet kit.
11. When unloading, material will begin to pile up behind the truck/trailer. The load will stop moving
when the pile of material gets too high. Reduce engine RPM’s and move the truck/trailer forward
(load will begin to move again). Repeat until the material is completely unloaded.
12. After loading/unloading is completed, reduce engine RPM’s to idle and stop the oor with all slats
in the forward position by pushing the ball valve handle in to the fully open position.
13. Fully retract KEITH®WALKING FLOOR®Sweep System (if equipped) to the front of the truck/
trailer.
14. Close and secure the rear truck/trailer door(s).
15. Disengage PTO.
EMERGENCY STOP: In case of emergency the oor can be stopped in one of the following ways:
• Disengage the PTO.
• Push the ball valve fully open.

4.0 Maintenance
DANGER: The extreme forces exerted by the oor, when in operation, can result in damage
to equipment, as well as cause serious injury or death. Always follow lockout/tagout procedures.
Switch o󰀨 the Power Take O󰀨 (PTO) and manually push the ball valve to the fully open position
during maintenance and/or service work.
4.1 Life Extending Practices
• Follow the Start-Up procedures in this manual.
• Use only clean oil, free from contamination.
• Regularly inspect the system for loose bolts. Loose cylinder barrel clamp bolts and ooring bolts
are the most common cause of severe damage to the drive or ooring.
• Be aware of the pressures your system typically runs at (with and without loads). Increased
pressure can indicate potential problems.
4.2 Preventative Maintenance
4.2.1 Monthly Service (25 operating hours)
• Check the system for hydraulic leaks.
• Check the operating temperature. No single component should be warmer than 140 ºF [60 °C]
while the system is running.
• Torque cylinder barrel clamp bolts and oor bolts. (See 4.3 Maintenance section for special
values and instructions.) Any bolts that were loose should be checked weekly until found to be
tight.
• Pressure wash drive unit, sub-deck, and slats (recommended quarterly, minimum twice per
year).
4.2.2 6-Month Service (150 operating hours)
• Change the oil lters.
• Cycle the system briey in both directions and observe to ensure proper operation. Do NOT
allow material to compact against the front of the trailer or against the rear doors.
• Inspect cross-drive support bearings, wearpads, tubes and shoes for wear. (See 4.4 Cross-
Drive Wear Component Diagram section). Replace as needed.
• Inspect oor wear bearings and seals for excessive wear (especially above the tires). (See 4.5
Flooring Wear Component Diagrams section) Replace as needed.
• Inspect oor slats for wear. If discharge end of slats are worn down more than 75% of original
material thickness rotate all oor slats, end for end, to increase life of the oor. If oor has
already been rotated, contact KEITH for replacement slats.

* Bolts installed using thread lock should be checked using a setting that is 5 ft-lbs [7 Nm] less than the
above specied value. If the bolt moves then you should remove it, clean it, apply new loctite to the
threads and torque it to the full specied value.
** Over tightening the barrel clamp bolts can deform the cylinder barrel shape causing the system to not
function properly.
