1.0 Safety
1.1 General Safety
1.1.1 Intended Function and Expected Use:
1.1.1.1. The KEITH®CleenSweep®system is a winch system primarily intended to restage clean
out systems used in live oor trailers. The system is supplied as a kit primarily intended
for installation into mobile trailers or truck bodies. It is powered by either a hydraulic
motor or an electric motor. The basic system is controlled by a mechanically-actuated pull
valve or an electric push button. The system is compatible with options and accessories
to improve performance. For example, it can be electrically controlled by hardwired or
wireless remote.
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 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 hydraulic power source must not exceed the pressure and ow ratings. A relief valve
is installed for the CleenSweep®system, but a relief valve should be installed for the
overall system to ensure the maximum pressure is not exceeded.
1.1.2.4. Control circuitry must not be altered or bypassed.
1.1.2.5. Safeguards must not be altered or bypassed.
1.1.2.6. The user and system designer must understand the characteristics and safe handling
requirements of the material that is being conveyed.
1.1.2.7. 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.

1.1.5 Hydraulic Oil Safety
1.1.5.1. See the Material Safety Data Sheet (MSDS) for the oil used in your system for further
information about hydraulic oil safety.
1.1.5.2. 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.
1.1.5.3. Do not use high pressure systems in the vicinity of ames, sparks, and hot surfaces. Use
only in well ventilated areas.
1.1.5.4. Use only designated appropriate ll and drain ports for the oil.
1.2 Design / Installation Safety
1.2.1 Electric Components and Installation
1.2.1.1. KEITH recommends connecting to earth ground (whenever possible).
1.2.1.2. Wiring must be connected consistent with local codes and regulations, including
electromagnetic interference regulations.
1.2.1.3. Adequate electric overcurrent protection must be provided.
1.2.2 Hydraulics
1.2.2.1. 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.
1.2.2.2. Hydraulic piping should be supported and isolated from vibration. Contact KEITH for
recommendations on installation.
1.2.2.3. Place protective shrouds around the hydraulic tubing in any areas that may have
operators or people frequently nearby.
1.2.3 Controls
1.2.3.1. 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).
1.2.3.2. Control devices must be located outside of danger zones, such that any exposed persons
in danger zones are visible from the control station.
1.2.3.3. An acceptable means must be provided to monitor the status and movement of the load.

3.4.2 Option 2: High Mount - Winch near top inside of trailer, strap roller on cap plate
High Mount - Guide rails and a metal cap plate (not supplied by KEITH Manufacturing Co.) can be installed
to allow the tarp to be pulled up higher in the front of the trailer. Doing so will reduce the possibility of
material getting behind the tarp. A strap roller assembly is required, because the angle of the strap needs
to change direction from vertical to horizontal when the tarp is fully extended. Mount the winch near the
top center of the front wall of the trailer. The winch should be mounted with the strap up. Ensure all moving
parts of the winch have adequate clearance.
3.4.2.1. Winch Installation Inside Trailer Near Top of Front Wall
NOTE: Front wall of trailer may need to be reinforced to withstand the forces created by the winch.
1. Locate and mark a centerline up the front wall of the trailer. NOTE: It is crucial that strap roller
