Introduction

Owner responsibility

WARNING : Processing of concrete and stone by methods such as cutting, grinding or drilling, especially during dry operation, generates dust that comes from the material being processed, which frequently contains silica. Silica is a basic component of sand, quartz, brick clay, granite and numerous other minerals and rocks. Exposure to excessive amount of such dust can cause:
Respiratory disease (affecting your ability to breathe), including chronic bronchitis, silicosis and pulmonary fibrosis from exposure to silica. These diseases may be fatal; Skin irritation and rash.
Cancer according to NTP and IARC */ National Toxicology Program, International Agency for Research on Cancer.
Take precautionary steps:
Avoid inhalation of and skin contact with dust, mist and fumes.
Wear and ensure that all bystanders wear appropriate respiratory protection such as dust masks designed to filter out microscopic particles. (See OSHA 29 CFR Part 1926.1153)
To minimize dust emissions, use water to bind the dust, when feasible. If dry operation is necessary, use an appropriate dust extractor.

It is the owner’s/employer’s responsibility that the operator has sufficient knowledge about how to use the product safely. Supervisors and operators must have read and understood the Operator’s Manual. They must be aware of:

Product description

The Husqvarna Wet Industrial Vacuum Cleaner is a slurry collector. The liquids are sucked through the inlet valve at high speed via the suction hose. The liquid is collected in a container. The pump variants offer the possibility to evacuate the liquid via the evacuation pump.
On variants without the evacuation pump the liquid can be drained by the evacuation valve.
A floating device protect the motor from liquid.
The W 70 and W 70 P have an extra filter to filter the slurry foam from particles.
To protect the product and prolong the lifetime it is always recommended to use bags to collect and filter the largest particles.
Intended use
The product is intended for domestic and commercial use, for example in hotels, schools, hospitals, factories, shops, offices and rental businesses to vacuum and collect liquid none explosive, flammable or combustible.
The W 70 and W 70 P can be used for dry applications temporarily. Dry bags should then always be used and the filter should be changed to a Hepa filter, sold as an accessory.
