2.7.6 Vibration
CAUTION
Hand-arm acceleration values exceeding 2.5 m/s² can oc-
cur, depending on the spray device used. Longer periods
of use may lead to poor blood circulation in the hands due
to vibration.
A general maximum period of use cannot be specified, be-
cause this depends on several influencing factors:
 Personal tendency to suffer from poor circulation (symp-
toms such as frequently cold fingers, tingling sensation
in the fingers etc.).
 Low ambient temperature. Wear warm gloves to protect
your hands.
 Grasping tightly reduces the circulation of blood in the
hands.
 Working without interruption amplifies the effects of vi-
bration induced blood circulation problems.
Note
We recommend consulting a doctor if corresponding
symptoms occur repeatedly after regular, long-duration
use of the spray device.
2.8 Protective gear
WARNING
Risk of injury through incorrect or incomplete protective
gear

Intended use

This product is used for actuating manually operated spray
devices from WOMA GmbH, used at permissible operating
pressures of up to 1100 bar.
In conjunction with a high-pressure water jet machine,
spray tube / spray lance and a water tool, this product is
designed for targeted application of a high-pressure fluid to
a surface for the purpose of removing, cleaning etc. vari-
ous surfaces and materials such as steel, concrete etc.
This can be achieved using various different water tools
from WOMA GmbH.
This product is only to be used with water conforming to
the WOMA water quality guideline (see Chapter 12.1 Wa-
ter quality guideline). The maximum permissible fluid vol-
ume flow rate is 45 l/min.
Please check the safety devices on the product each time
before use (see chapter 6 Startup).
Intended use also includes using only original spare parts
from WOMA GmbH.
Any use other than, or beyond the specified intended use
is regarded as incorrect use.
Observe the safety instructions and warning notices.
3.1 Foreseeable misuse
The device is equipped with a trigger safety catch. This
prevents unintentional actuation of the trigger.
 Never lock the trigger.
 Do not block or modify the trigger catch.
 Do not use spray equipment shorter than 750 mm
(measured from trigger to nozzle).
 Do not use the spray device for cleaning the high-pres-
sure water jet machine or for mechanically loosening
contamination or baked deposits (e.g. when cleaning a
cement kiln).
 Do not use the spray device as a lever (crowbar).
 Never use liquids containing solvents or undiluted acids
and solvents for spraying. This includes e.g. petrol, paint
thinner or heating oil. The spray mist is highly flamma-
ble, explosive and poisonous.
 Materials containing asbestos or other substances
harmful to health may not be sprayed.
