3. PRODUCT INTRODUCTION
3.1 OVERVIEW
The product is a hydraulically operated breaker. It can be used on any carrier which
meets the necessary hydraulic and mechanical installation requirements. The unit
functions by repeatedly raising a steel piston and driving it down onto the head of a
removable breaking tool.
No additional pressure accumulators are necessary since the integrated pressure
accumulator absorbs hydraulic pressure peaks. The impact energy of the hammer is
almost constant and independent of the carrier's hydraulic system.
3.2 REMOVAL FROM PACKAGE
Remove all the steel belts from the package. Open the package and remove all
plastics covering the product.
Recycle all package materials (steel, plastic, wood) properly.
Check that the product is in good condition and that there is no visible damage.
Check that all ordered parts and accessories have been enclosed with the product.
Some options may be provided by your local dealer like installation kits; including
hoses and mounting bracket.
3.3 LIFTING INSTRUCTIONS
Use a hoist when lifting components which weigh 23 kg (50 lb) or more, to avoid
back injury. Make sure all lifting equipment is in good condition and are in the
correct capacity. Be sure hooks are positioned correctly. Lifting eyes are not to be
side loaded during a lifting operation. Do not use the hammer's tools for lifting.

1655 Heavy Duty
Product introduction
PROVIDED LIFTING POINTS
Use the lifting eyes located on the product housing only to lift or handle the product
itself. The lifting capacity calculation is based on the product's working weight
including a normal working tool and an average sized mounting bracket.
Warning! To avoid falling objects, do not use the product to lift other products.
Use the lifting eyes located on the product housing only to lift or handle the
product itself.
The maximum allowed total weight is shown on the product's CE-plate and
specification page. See “Hammer specifications” on page 66. If the weight exceeds
the maximum allowed total weight shown on the CE-plate and specification page,
you have to use other lifting points/methods than originally provided on the product.
The other threaded holes on the product (for example on the hammer powercell) are
intended for handling single parts only. It is forbidden to lift the entire assembly by
using these threaded holes (for example on the cylinder outer surfaces). For
handling the parts, see product workshop documentation for suitable lifting
methods and lifting adapters.
LIFTING EYE SCREWS
Tighten the lifting eye screws completely. Put a burden on the lifting eye only if the
screw is properly tightened to the housing.
Failure to properly tighten the screw before allowing load pressure on the
lifting eye may cause lifting eye to break and free fall of the product.
If you use mechanical tools for tightening, make sure not to overstrain the shank.
Before lifting make sure that the rope and/or hook is stretched.
When two lifting eye screws are used, the lifting capacity depends on the angle of
the lifting chains. The angle should not be less than 45°, as shown in the illustration.
When the lifting eye screws are tightened, both rings should be aligned.
The loading capacity calculation applies to temperatures between -10 °C (14 °F)
and 40 °C (104 °F).
Before reuse of lifting eye screws make sure there are no surface flaws (for example
rust, pits, voids, folds and seams, deformation of the ring, or missing or broken
threads).
The local, national safety standards for machines and lifting-equipments must
always be strictly observed.
Note: Before starting to operate the hammer, always replace the lifting eye with a
blanking screw.

169400_ENG-1
R010356
Airborne pollutants are microscopic particles, which will damage your health, when
inhaled. Airborne pollutants on construction sites can be, for example, silica dust,
oil fumes or diesel exhaust particles, visible or invisible. Especially in demolition
sites, there may be other dangerous substances, such as asbestos or lead paints or
other chemical substances.
Page 18 - Operation
COPYRIGHT © 2015 SANDVIK MINING AND CONSTRUCTION OY
1655 Heavy Duty
Safety
The effect of airborne pollutants may be immediate if the substance is poisonous.
The main danger with airborne pollutants comes from long term exposure, where
particles are inhaled but not removed from the lungs. The disease is called silicosis,
asbestosis or other, and will result in death or serious injury.
To protect yourself from airborne pollutants, always keep excavator doors and
windows closed during operation. Excavators with pressurized cabins should be
utilized in hammer operation. Proper maintenance of fresh air filters of the
excavator is essential. Where pressurized cabins are not available, proper respirators
must be utilized.
Stop working, when bystanders are in the area of airborne pollutants and make sure
they have proper respirators. Respirators are as important for bystanders as hard
hats.
Respirators for both operator and bystanders must be approved by the respirator
manufacturer for the application in question. It is essential that the respirators
protect from the tiny dust particles which cause silicosis and which may cause other
serious lung diseases. You should not use the equipment until you are sure the
respirators are working properly. This means the respirators must be checked to
make sure that it is clean, that its filter has been changed, and to otherwise make sure
the respirator will protect in the way it is meant to.
Always make sure dust has been cleaned off your boots and clothes when you leave
your shift. The smallest particles of dust are the most harmful. They may be so fine
that you can not see them. Remember, you MUST protect yourself and bystanders
from the danger of breathing or inhaling dust.
Always follow local laws and regulations for airborne pollutants in the working
environment.

5. OPERATION
5.1 OPERATING INSTRUCTIONS
RECOMMENDED USE
The hammer is designed to be used in breaking concrete, road surface or asphalt,
hard or frozen ground. It can be also used in breaking moderate sized boulders as
well as in demolishing reinforced structures and for major excavation and clearing
work. Your local dealer will gladly give you more information.
OPERATING CONDITIONS
Principle of installation
Almost all carriers meeting mechanical and hydraulic requirements can be used to
operate the attachment. See “Hammer specifications” on page 66. The product is
installed on the carrier much in the same manner as installing a bucket or other
attachments. A flange mounted attachment requires a separate mounting bracket.
If the carrier has already auxiliary hydraulic circuit, the installation requires only
suitable hoses and fittings. If the carrier does not have suitable kit to run the
attachment, one must be built. This may require installation including new piping
and additional valves such as directional valve and pressure relief valve.
Suitable kits can be ordered from the local dealers, from carrier manufacturers and
their dealers or from third party suppliers.
Hydraulic oil
In general the hydraulic oil originally intended for the carrier can be used with this
product. See “Requirements for hydraulic oil” on page 46.
Operating temperature
The operating temperature is -20 °C (-4 °F) to 80 °C (176 °F). If the temperature is
lower than -20 °C (-4 °F), the hammer and tool have to be preheated before any
operations can begin, in order to avoid breaking the accumulator's membrane and
the tool. During operation they will remain warm.
Note: The temperature of the hydraulic oil must be monitored. Ensure that oil grade
and monitored oil temperature together guarantee correct oil viscosity. See “Oil
specifications” on page 47.
Noise dampening
Operating the hammer near residential areas or other noise sensitive areas can cause
noise pollution. In order to avoid unnecessary noise, please follow these basic rules:
1. When operating with the hammer, keep the tool at 90 degree angle to the
material and the feed force in-line with the tool.
COPYRIGHT © 2015 SANDVIK MINING AND CONSTRUCTION OY
Operation - Page 25
Operation
1655 Heavy Duty
2. Replace or fix all parts that are worn out, damaged or loosened. This not only
saves your hammer but it also decreases the noise level.
PRINCIPLES OF BREAKING
To increase the hammer's working life, pay particular attention to correct working
methods and how to choose the correct tool for the job. There are essentially two
ways of breaking with a hydraulic hammer.
Penetrative breaking (or cutting)
In this form of breaking a moil point or chisel tool is forced inside the material. This
method is most effective in soft, layered or plastic, low abrasive material. The high
impact rate of the small hammers makes them ideal for penetrative breaking.
Impact breaking
With impact breaking, the material is broken by transferring very strong mechanical
stress waves from the tool into the material. Impact breaking is most effective in
hard, brittle and very abrasive materials. The high impact energy of the big
hammers makes them ideal for impact breaking. The best possible energy transfer
between the tool and the object is achieved with a blunt tool. The use of a chisel tool
in hard material will cause the sharp edge to wear very quickly.
CHOOSING TOOLS
A selection of standard and special tools to suit each application are available. The
correct type of tool must be selected to get the best possible working results and
longest life time for the tool. Choosing the best tool type for an application may
require some testing, please consult with your local dealer. See “Tool
specifications” on page 69.
Chisel, moil point and pyramid
■ For sedimentary (e.g. sandstone) and weak metamorphic rock into which the
tool penetrates.
■ Concrete.
■ Trenching and benching.

Operation
Blunt tool
■ For igneous (e.g. granite) and tough metamorphic rock (e.g. gneiss) into which
the tool doesn't penetrate.
■ Concrete.
■ Breaking boulders.
It is important to choose a tool, which is suitable for your hammer and for the
application you are working on. The tool selection available depend on hammer
model. See “Tool specifications” on page 69.
CHECKING THE SERVICE INTERVAL STATUS
You can check the service interval status by firmly tapping the sensor three (3) times
in 1- to 3-second intervals. If the pulse is not timed correctly, you need to wait five
seconds before trying again.

5.2 DAILY OPERATION
GENERAL GUIDELINES
-
A safety screen is recommended to protect the operator from flying debris.
Keep the cabin windows and doors closed during operation.
-
Keep the tool at a 90 degree angle at all times. If the object moves or its surface
breaks, correct the angle immediately. Keep the feed force and tool aligned.
-
Keep the tool shank well greased during operation. Regular visual inspections
during operation are recommended. An unlubricated tool shank requires more
frequent greasing intervals. A tool shank covered with excessive grease
requires less frequent greasing intervals.
-
To use the hammer most efficiently when breaking large objects, concentrate
Page 28 - Operation
COPYRIGHT © 2015 SANDVIK MINING AND CONSTRUCTION OY
1655 Heavy Duty
Operation
on small steps from the outer edge towards the middle.
-
Do not strike in one spot for more than 15 seconds at a time. If the object does
not break, or if the tool does not penetrate, stop the hammer and change the
position of the tool. Working too long in one spot will create stone dust under
the tool. Dust dampens the impact effect and produces heat.
-
Listen to the hammer's sound when you are using it. If the sound becomes
weaker and the impact less efficient, the tool is misaligned with the material
and/or there is not enough down force on the tool. Realign the tool and press the
tool firmly against the material.
-
Do not let the tool move outwards from the hammer when it penetrates. Keep
the down-pressure on the hammer while breaking.
-
When demolishing vertical structures (such as brick walls), place the tool

Operation - Page 29
;; ;;
; ;
Operation
1655 Heavy Duty
against the wall at a 90 degree angle.
-
When breaking concrete, hard or frozen ground, never strike and pry with the
tool at the same time. The tool may break. Bending may be caused by stones
inside hard or frozen ground. Be careful and stop striking if you find sudden
resistance under the tool.
-
When breaking hard or frozen ground, use the benching method. Start with
clearing a small area from the edge. Then continue by breaking material
towards the open area.
-
Do not use the hammer tools to move rocks. The stone claws are designed for
this purposes.

WORKING PROCEDURE
Warning! Protect yourself and your neighbourhood against flying chips of
rock. Do not operate the hammer or carrier if someone is too close to the
hammer.
Do not use the hammer, as a standard assembly, under water. If water fills the
space where the piston strikes the tool, this generates a strong pressure wave
that may damage the hammer.
Warning! To avoid falling objects, do not use the product to lift other products.
The lifting eyes located on the product housing are to be used solely to lift or
handle the product itself. See “Lifting instructions” on page 8.
1. Prepare the carrier for normal excavation work. Move the carrier to the required
position. Set the drive to neutral.
2. Set the engine speed to the recommended engine RPM for correct amount of oil
supply.

3. Carefully operate the carrier controls to place the hammer and boom into the
breaking position. Quick and careless boom movements can result in damage to
the hammer.
4. Use the excavator boom to press the hammer firmly against the object. Do not
pry the hammer with the boom. Do not press too hard or too gently with the
boom. The correct force is applied, when the tracks start to lift slightly from the
ground.

1655 Heavy Duty
5. Place the tool against the object at a 90 degree angle. Avoid small irregularities
on the object which will break easily and cause either idle strokes or an
incorrect working angle.
6. Start the hammer.
7. Stop the hammer quickly. Do not allow the hammer to fall down and make idle
strokes when an object breaks. Frequent idle strokes have a deteriorating effect
on the hammer. If the hammer falls through, the housing wears out more
quickly.

5.3 MOUNTING AND DISMOUNTING THE HAMMER
REMOVAL FROM CARRIER
Warning! The hammer must be secured from rolling over when disconnecting
from the carrier. Only use a skilled operator to position the carrier for hammer
removal!
Warning! Hydraulic pressure inside the hammer must always be released
before opening hose connections!
Warning! Hot hydraulic fluid can cause severe injuries!
1. Position hammer horizontally on the floor. If the hammer is going to service,
remove the tool.
2. Stop the carrier engine. Operate boom and hammer controls to release pressure
trapped inside hoses. Wait ten minutes for oil pressure to drop.
3. Close hammer inlet and outlet lines. If quick couplers are used, disconnection
automatically closes hammer lines. If hammer line includes ball valves, please
make sure that they are closed.
4. Disconnect hoses. Protect environment from oil spills. Plug the hoses and the
hammer inlet and outlet ports.
5. Remove bucket pins and other parts.
6. The carrier can be moved aside.
INSTALLATION
1. Install hammer in the same manner as mounting a bucket. Install bucket pins.
2. Connect hoses. Hammer inlet port is marked on the valve body with "IN" and
outlet port with "OUT". An installation inspection must be carried out after the
product has been mounted on the carrier. In the installation inspection certain
specifications (such as operating pressure, oil flow) are checked so that they are
within given limits. See “Hammer specifications” on page 66.

3. Open hammer inlet and outlet lines.
5.4 MOVEMENT
The transportation and parking positions are shown below. When moving with the
hammer, ensure that it isn't too close and doesn't point at the cabin window.
5.5 SPECIAL CONDITIONS OF USE
Special conditions of use are conditions in which the hammer is used for some work
other than normal breaking or demolition, such as:
■ Hammer tunneling
■ Foundry cleaning
■ Underwater operations
■ Operations in extremely low or high temperatures
■ Use of special hydraulic fluids
■ Hammer operations with a special carrier (e.g., an extra long boom)
■ Other special conditions
Special conditions of use may require modifications to the attachment, special
operating techniques, increased maintenance or special wear items. If you are
planning to use the hammer under a special condition of use, please consult your
local dealer for instructions.

Operation
UNDERWATER OPERATION
Use environmental friendly oil and tool grease when you are using the hammer
under water.
Warning! If you are using the hammer under water, protect yourself and your
surroundings against compressed water/air spray and possible broken
compressed air hoses.
Warning! If you are using the hammer under water, check the stability of the
carrier and the hammer. Water gets inside the hammer, causing it to weigh
more. Due to the added water weight, lift the hammer carefully out of the
water.
The hammer as a standard assembly, must not be used under water. If water
fills the space where the piston strikes the tool, a strong pressure wave is
generated and the hammer may be damaged.
The latest hammer models can be modified for underwater operations for only short
periods. The operating principle in underwater hammering is to conduct pressurized
air through a built-in channel to the spaces above and below the piston. The air
pressure prevents water entering the hammer. The hammer as a standard assembly,
must not be used under water. If water fills the space where the piston strikes the
tool, a strong pressure wave is generated and the hammer may be damaged.
The wear resistance of the hammer parts is considerably lower under water than in
normal use. This is caused by corrosion and by the abrasive effect of mud in water.
After starting underwater hammering, the hammer must be inspected regularly, for
example after every half hour operation. Adapt the inspection intervals to the
working conditions. See “Maintenance intervals in underwater use” on page 54.
In underwater applications, the productivity of a hydraulic hammer is considerably
lower than in normal work. This is caused by:
1. The breaking object is not visible to the operator. This causes misalignment
between the tool and the object and unnecessary idle strokes.
2. The hammer must be inspected and greased more often than in normal
situations.
3. The hammer must always be completely serviced after working on underwater
job sites.

available for the greasing device, greasing device has malfunction or pressure hose
is damaged. Check also the grease hose conditions inside the housing.
GREASING INTERVAL
1. Tool shank must be well lubricated before installing tool.
2. 5-10 strokes from grease gun to tool bushings and tool at regular intervals.
3. Adapt interval and amount of grease to wear rate of tool and working
conditions. This can be anything between two hours and daily, depending on
material (rock/concrete) to be broken. See “Recommended greases” on page 40.
Insufficient greasing or improper grease may cause:
■ Abnormal wear of tool bushing and tool
■ Tool breakage
CORRECT GREASING

Carrier hydraulic oil
1655 Heavy Duty
2. CARRIER HYDRAULIC OIL
2.1 REQUIREMENTS FOR HYDRAULIC OIL
GENERAL REQUIREMENTS
In general the hydraulic oil originally intended for the carrier can be used with this
product. However, since working with the product heats the oil more than the usual
excavation work, the temperature of the oil must be monitored.
If the temperature of the hydraulic oil exceeds 80 °C (176 °F), an auxiliary oil cooler
is needed. The oil viscosity must be between 20-1000 cSt while the attachment is
being used.
When the product is used continuously, the temperature of the hydraulic oil
normalizes at a certain level depending on conditions and on the carrier. The
temperature in the tank must not exceed the maximum allowed.
The hammer must not be started if the ambient temperature is below freezing and
the oil is very thick. The machine must be moved to bring the oil temperature above
0 °C (32 °F) before hammering can start (viscosity 1000 cSt or 131 °E).
Page 46 - Lubrication

1655 Heavy Duty
Carrier hydraulic oil
OIL SPECIFICATIONS
Table below shows hydraulic oils recommended for hammer use. The most suitable
oil is selected in such a way that the temperature of the hydraulic oil in continuous
use is in the ideal area on the chart and the hydraulic system is used to best
advantage.
Problems due to incorrect hydraulic oil viscosity in the hammer:
Oil too thick
■ Difficult start up
■ Stiff operation
■ Hammer strikes slowly
■ Danger of cavitation in pumps and in the hydraulic hammer
■ Sticky valves
■ Filter bypass opens, impurities in the oil are not removed
COPYRIGHT © 2015 SANDVIK MINING AND CONSTRUCTION OY
Lubrication - Page 47
Carrier hydraulic oil
1655 Heavy Duty
Oil too thin
■ Efficiency losses (internal leaks)
■ Damage to gaskets and seals, leaks
■ Accelerated wearing of parts, because of decreased lubrication efficiency
■ Hammer strikes irregularly and slowly
■ Danger of cavitation in pumps and in the hydraulic hammer
Note: We strongly recommend the use of different hydraulic oils in the summer and
in the winter if there is an average temperature difference of more than 35 °C (63
°F). The correct hydraulic oil viscosity is thus ensured.
SPECIAL OILS
In some cases special oils (for example biological oils and non-inflammable oils)
can be used with hydraulic hammers. Observe the following aspects when
considering the use of special oils:
■ The viscosity range in the special oil must be in the given range (20-1000 cSt)
■ The lubrication properties must be sufficient
■ The corrosion resistance properties must be good enough
Note: Although a special oil could be used in the carrier, always check its suitability
with the hammer due to high piston speed of the hammer. Contact the oil
manufacturer or your local dealer for more information about special oils.
2.2 OIL COOLER
The correct place to connect the hammer return line is between the oil cooler and
the main filters. The hammer return line should not be connected before the oil
cooler. Routing the hammer return flow through the cooler, might damage either the
cooler, due to pulsating flow, or the hammer, due to increased back pressure.
The carrier hydraulic system must be able to maintain the temperature within an
acceptable level during the hammer operation. This is for two reasons.
1. Seals, wipers, membranes and other parts manufactured from the corresponding
materials can normally stand temperatures up to 80 °C (176 °F).
2. The higher the temperature is, the less viscous the oil gets thus losing its
capability to lubricate.
Page 48 - Lubrication
COPYRIGHT © 2015 SANDVIK MINING AND CONSTRUCTION OY
1655 Heavy Duty
Carrier hydraulic oil
A standard carrier, with a proper hammer circuit, meets the requirements of the
necessary cooling capacity. If the oil temperature tends to be too high during the
hammer operation, the following things must be checked:
■ The hammer circuit pressure relief valve is not open when the hammer is
operated.
■ The hammer circuit pressure drops are reasonable. Less than 10 bar (145 psi) in
the pressure line and less than 5 bar (75 psi) in the return line.
■ Hydraulic pumps, valves, cylinders, motors etc. and hammer do not have
internal leakages.
If all of the above mentioned things are in order, and the temperature of the
hydraulic oil still tends to be too high, extra cooling capacity is needed. Consult the
carrier manufacturer or dealer for details.
2.3 OIL FILTER
The purpose of the oil filter is to remove impurities from the hydraulic oil. Air and
water are also impurities in oil. Not all impurities can be seen with the naked eye.
Impurities enter the hydraulic system:
■ During hydraulic oil changes and refilling.
■ When components are repaired or serviced.
■ When the hammer is being installed on the carrier.
■ Because of component wear.
Normally the existing main oil filters of the carrier are used as hammer circuit return
line filters. Consult the carrier manufacturer or your local dealer concerning
instructions for the filter change intervals.
In hydraulic hammer work the carrier oil filter must fulfil the following
specifications:
■ The oil filter must allow maximum particle size of 25 microns (0.025 mm).
■ The oil filter material must be artificial fibre cloth or very fine gauge metallic

1. ROUTINE MAINTENANCE
1.1 OVERVIEW
This product is a precision made hydraulic machine. Therefore great care and
cleanliness should be taken when handling any of the hydraulic components. Dirt is
the worst enemy in hydraulic systems.
Handle the parts carefully and remember to cover any cleaned and dried parts with
clean lint-free cloth. Do not use anything other than purpose designed materials for
cleaning hydraulic parts. Never use water, paint thinners or carbon tetrachloride.
Components, gaskets and seals in the hydraulic system should be oiled with clean
hydraulic oil before assembly.
1.2 INSPECTION AND MAINTENANCE BY THE OPERATOR
Note: The time intervals given refer to the carrier hours while the attachment is
installed.
EVERY TWO HOURS
■ Check that the grease cartridge is not empty. Replace if necessary.
■ Check that the tool has received sufficient grease.
■ Grease manually if the automatic greasing device is not in use. See “Manual
greasing” on page 44.
■ Observe hydraulic oil temperature, all lines and connections as well as impact
efficiency and evenness of operation.
■ Tighten loose connections.
EVERY 10 HOURS OR AT LEAST ONCE A WEEK
■ Remove the tool retaining pin and the tool and check their condition. Grind the
burrs away if necessary. See “Changing the tool” on page 55.
■ Check that the tool has received sufficient greasing. Grease more frequently, if
necessary.

1655 Heavy Duty
Routine maintenance
EVERY 50 HOURS OR AT LEAST ONCE A MONTH
■ Check the tool shank and tool bushings for wear. See “Changing the tool” on
page 55. See “Lower tool bushing” on page 58.
■ Check the hydraulic hoses. Replace if necessary. Do not let dirt get into the
hammer or hoses.
■ Check that the hammer moves normally inside the housing and that vibration
dampening elements (pads and buffers) are in good condition.
■ Check the condition of wear plates by moving hammer with a pry bar from side
to side inside housing. The maximum allowed clearance is approximately ±10
mm.
1.3 INSPECTION AND MAINTENANCE BY THE DEALER
Note: The times given refer to the carrier hours while the attachment is installed.
INITIAL 50-HOUR INSPECTION
It is recommended to have the first inspection done by your local dealer after 50 to
100 operating hours. Contact your local dealer for more information about the initial
50-hour inspection.
EVERY 1000 HOURS OR ONCE A YEAR
This service is recommended to be done by your local dealer after 1000 operating
hours or at least once a year. Neglecting the annual service can cause severe damage
to the hammer.
Your local dealer will reseal the hammer, replace the accumulator membranes and
replace safety decals as needed. Contact your local dealer for more information
about annual servicing.

1.4 MAINTENANCE INTERVALS IN SPECIAL APPLICATIONS
The service interval is considerably shorter in special applications. See “Special
conditions of use” on page 36. In special applications, please consult your local
dealer for the correct service intervals.
MAINTENANCE INTERVALS IN UNDERWATER USE
After every half hour operation
■ Grease the tool shank and the tool bushings through the grease nipples.
■ Check that the hammer moves normally inside the housing and that the buffers
are in good condition.
■ Check all hoses and connections.
■ Check the operation of the air pressure switch.
Daily maintenance
■ Remove the retaining pin and the tool for inspection. Grind the burrs away if
necessary.
■ Check that the tool has received sufficient grease.
■ Service the hammer after underwater jobs.
The hammer must be totally dismantled and serviced after working underwater.
Neglecting a hammer service after underwater work can cause severe damage to the
hammer.
The hammer as a standard assembly, must not be used under water. If water
fills the space where the piston strikes the tool, a strong pressure wave is
generated and the hammer may be damaged.
1.5 OTHER MAINTENANCE PROCEDURES
WASHING THE ATTACHMENT
When working with attachment and removing it from the carrier, dirt (mud, rock
powder etc.) can become attached to it. Wash the outside of the product with a steam
washer before sending it to the workshop. Dirt can cause difficulties in disassembly
and assembly otherwise.
CAUTION! Plug the pressure and return line and other connections before washing
the product or else dirt can enter into it and this may cause damage to the
components.
