1.2. Introduction
Please ensure that you read this Operation & Maintenance Manual in conjunction with the
Health & Safety Manual before operation.
Within this manual, the health and safety risks are highlighted with specific symbols. These
will be referenced to sections within the Health and Safety Manual which you are required to
read. The sections to refer to in the manual will be labelled at the end of the highlighted
statement (Ex. H&S Section 2). There are three symbols that will be used to differentiate the
levels of severity. They are as follows:
o : This is the symbol for . This means that if an accident were to happen,
it would cause minor to moderate injury.
o : This is the symbol for . This means that if an accident were to happen,
it could result in a serious injury or possible death.
o : This is the symbol for . This means that if an accident were to happen,
it will result in death or serious injury. This will only be shown for the most extreme
cases.
It is imperative that these symbols are paid attention to as to avoid any sort of injury.
Notices
Carefully read the notices of this manual because they give important information concerning
safe installation, use and maintenance. Familiarize yourself with the workings of the machine
to rapidly switch it off and eliminate pressure.
This manual is an integral and essential part of the product; it will be consigned to the user to
ensure the training/information for personnel.
The manufacturer does not assume responsibility for damage caused to persons, things or to
the machine, in the case of improper use. Carefully preserve this manual for any further
consultation.
Identify the model of your machine by reading the details on the identification plate. Upon
delivery, inspect the machine / accessories for any damage, which may occur during transport.
CAUTION!Always follow the recommended operating procedures. Do not misuse the
equipment as this could result in injury or mechanical breakdown!

1.3. Scope of this Manual
This manual provides operation, maintenance, and safety instructions for the Jetter. Where
the Jetter has been fitted with proprietary components, details of these are also included in
this manual.
This manual is compiled to match the Scope of Supply detailed in Section 2. All specifications,
descriptions and parts lists refer only to the components in the version of the unit detailed in
this scope of supply.
Maintenance instructions included in this manual include:
 Routine maintenance to be carried out at specific times.
 Maintenance of the high-pressure pump.
Repairs to the pump crankcase are not considered maintenance operations as these should
be undertaken only by HARBEN INC, their approved agents, or at least competent automotive
engineers.
1.4. The Trailer Jetter
Harben® high pressure jetters and systems have been designed to the highest standards. It
is important that you take time to read the information provided here so that you understand
how to make the most of the equipment and use it in accordance with the instructions.
Harben® jetters are powerful pieces of industrial equipment and should only be operated by
competent users who understand that serious injury or death can occur through misuse.
The Jetters described in this operation and maintenance manual are intended to be used for
high-pressure water jetting and pumping applications.
They will remove soft blockages, tree roots and hard scale, liquefying fats and restoring drain
flow by blasting high-pressure water through a drain nozzle connected to the end of a high-
pressure hose. Some models can be fitted with jump jets kits to increase the effective cleaning
distance.
Harben trailer Jetters use a diesel or a gas engine to power a high-pressure water pump up
to 5,000 psi and 18 gpm.
Additional accessories can be purchased from Harben®, such as: floor cleaners, jetting guns
and jet pumps which extend the range of work that can be carried out with the jetter. Safety
information relating to individual accessories is provided later in this section.

Scope of Supply
2.1. Scope of Supply
Unit:
E180 Trailer Jetter
ET180 Trailer Jetter
E-Series Trailer Jetter
2.2. Pump Assembly
Figure 2.1 defines the components of the Jetter assembly as follows:
The pump is driven by an industrial diesel engine.
The engine drives the pump via a 2:1 reduction gearbox which reduces the pump rpm down
to the correct shaft speed.
Water is fed from a mains supply into a plastic water storage tank. The tank supplies
the pump with a positive head of pressure via an inline hypro strainer that filters the
water to approximately 80 microns.
The ‘P’ Type 8 22 radial piston high-pressure diaphragm pump is driven by an
industrial diesel engine through a 2:1 reduction gearbox.
The water is directed by a divert valve, to a hydraulically driven hose reel with up to 500 feet
of ½” hose, or at low pressure ‘dumped’ back to tank.
The system is protected from over pressurization by a safety relief bursting disc.
The engine and system pressure can be monitored at the control panel situated at
the rear of the Jetter.
2.3. Detailed Drawings
Detailed drawings and parts lists for the above components are provided as follows:
The pump is detailed in Section 7.
Details of other parts and assemblies are included at Section 10.

3.2. Technical Description
3.2.1. Primary Components
The primary components of the Jetters are illustrated in Figures 2.1-2.6 which are as follows:
 A prime mover in the form of an industrial diesel engine drives a Harben P-Type high-
pressure pump.
 The pump can produce high-pressure water up to 4000 psi.
 Note: See above or section 7 for performance options.
 A hydraulic driven hose reel contains up to 500 feet of single-wire braid high-pressure
hose that uses either a nozzle or gun attachment to deliver the high-pressure water to
the work application. The E180 has a rotating hose reel whereas the E-Series has a
fixed hose reel.
 Plastic water tank(s) act as a reservoir to ensure the water is settled and non-turbulent.
This allows a smooth, uninterrupted supply with a positive head of pressure to the inlet,
maximizing the full potential of the pump.
 The pressure valve directs high-pressure water to the main jetting hose or diverts it
back to the tank.
 The control panel includes the engine controller, pressure gauge, throttle, high-
pressure selector, jump jet valve, and hydraulic hose reel controls.
 A Hypro 80 micron mesh inline strainer is fitted to the suction line between the tanks
and the pump inlet.
NOTICE: This is a critical component which ensures that no contaminants are drawn
into the pump inlet. This filter must be inspected and cleaned daily, if it becomes
blocked it will cause the pump to cavitate.
3.2.2. Engine Monitoring
Engine oil pressure and hours run are monitored on the engine control panel.

Operation
4.1. Operating Conditions
Operators of water jetting equipment should be fully conversant with the 'WJTA Code of
Practice for the use of high-pressure water jetting equipment’, hereafter referred to as 'The
Code of Practice'. A copy of The Code of Practice is available upon request.
Please ensure that you read this Operation & Maintenance Manual in conjunction with the
Health & Safety Manual before operation.
4.2. Daily Checks
 pump oil level
 gearbox oil level
 water filter cleanliness
 engine oil level
 tank water level
4.3. Pre-start Checks & Procedures
1. WARNING! In cold weather check that machine is not frozen before starting (see
Antifreeze section 4.11). Serious injury can occur from ice bullets. (H&S Sections 3
and 7)
2. Only operate the machine in a well-ventilated area. (H&S Sections 3, 8, 9, and 12)
3. Ensure the towing vehicle and trailer hand brakes are applied. (H&S Sections 3, 11,
and 13)
4. To fill water tank, connect water supply to the hydrant fitting on the street side of the
trailer. (NOTICE: To comply with water authority bylaws never fill the tank by putting
a hose directly inside). The water will fill the tank via an appropriate filling point.
Overfilling the tanks will overload the trailer axle(s) and could make it
dangerous. (H&S Sections 3 and 13)
5. Feed off the hose reel approximately 10 feet of high-pressure hose. Do not fit the
nozzle or gun at this point! (H&S Section 3, 6, and 16)
6. WARNING! Inspect hose before using. Damaged hose can lead to serious injury
if put under pressure. (H&S Section 3, 6, and 16)
