2. Designed purpose of use
The AVANT Pressure washer is an attachment that is suitable for use with AVANT compact loaders that are
shown in Table 1. The Pressure washer is easy to take with anywhere with the Avant loader. It can be
connected directly to tap water supply, or water can be taken with the inlet hose from any reservoir.
The attachment can suck water via inlet hose up to 3 meters below the level where the unit is. This is a very
useful feature when taking water from a tank, reservoir, or lake, for example. The attachment is equipped with
a 20 m pressure hose, hose reel, and washing gun. The inlet hose is not delivered with the attachment, and it
must be purchased separately. The pressure washer can also be used to pump other liquids than clean fresh
water. However, dirty water, or other fluid that has abrasive particles, can damage the pump, and will cause
the pump to wear down quickly. The pump must be flushed with fresh water after other fluids have been used.
The Pressure washer is not designed for any other use than what is specified in this manual and must not be
used for any other purposes than what is intended for.
The attachment has been designed to require as little maintenance as possible. The operator can perform
regular maintenance tasks. All repair work can’t be performed by the operator, and demanding repair and
maintenance operations are to be left for professional technicians. All maintenance work must be done using
proper safety equipment. Spare parts must be identical with original specifications, which can be ensured by
using only original spare parts. A separate spare parts catalogue may be available, consult your Avant dealer.
Familiarise yourself with the manual's instructions regarding service and maintenance. Please contact your
AVANT dealer if you have additional questions about the operation or maintenance of the equipment, or if you
require spare parts or maintenance services.

3. Safety instructions for using the attachment
Please bear in mind that safety is the result of several factors. The loader-attachment combination is highly
powerful and improper or careless use or maintenance may cause serious personal injury or property
damage. Due to this, all operators must carefully familiarise themselves about correct use and the operator's
manuals of both the loader and the attachment before starting operation. Do not use the attachment if you
have not completely familiarised yourself with its operation and the related hazards.
DANGER
Misuse, careless use, or using an attachment that is in poor condition may
cause risk of serious injuries. Familiarise yourself with the
controls of the loader,
correct coupling procedure, and the correct way to operate the attachment at a safe
area. Study especially how to stop the equipment in a safe manner. Read all safety
precautions carefully.
Read all safety instructions carefully before handling the attachment
WARNING
When attaching an attachment to the loader, ensure that the locking pins of the
loader's quick attach plate are in the lower position and that they have locked
the attachment to the loader. Never lift or move an unlocked attachment.

This attachment is designed to be used by one operator at a time. Do not let others
near the danger area of the equipment when it is in use.

Always transport the attachment as low as possible to keep the centre of gravity low,
and keep the telescopic boom retracted during driving.
Risk of crushing under the attachment or the loader boom - Lower the
attachment firmly on the ground before leaving the driver’s seat.
Make sure that
the attachment is properly supported during any maintenan

leave the driver’s seat when the loader boom is lifted. Going under a raised
attachment or loader boom is dangerous, as the boom may lower due to loss of
stability, mechanical fault, or if another person operates the controls of the loader.
Risk of thrown objects - Keep a safety distance of at least 2 metres between a
pressure washer and any person in vicinity.
Keep in mind that the pressure
washer will throw water and other objects at high speed.
Stop the pressure washer if
the

vicinity. Pay attention to the contours of the terrain an
d other hazards, such as
branches and trees that can reach to the driver's area, loose rocks, and slippery
surfaces.

platform even temporarily.
Make sure to use only an attachment that is in good condition. Check the attachment
thoroughly in regular intervals. Do not modify the attachment in a manner that would
affect its safety. It is prohibited to drill holes on the attachment, and welding or other
