free from oil and grease.

slightly damp cloth.

pivoted and pushed all the way
down into the tool.

8 Disposal

CAUTION
Improper disposal of the equipment may have serious consequences: The burning of plastic components generates
toxic fumes which may present a health hazard. Careless disposal may permit unauthorized and improper use of the
equipment. This may result in serious personal injury, injury to third parties and pollution of the environment.
Lubricate the piston rods with oil when necessary. Mortar
adhering to the tool or the foil pack holder must be
cleaned off with a cloth before it hardens. Hardened
mortar can be removed only by mechanical means. Take
care to ensure that the tool is not damaged by cleaning.
Do not use a spray, steam pressure cleaning equipment
or running water for cleaning. Never dip or soak the tool
or its parts in solvents. Check that the piston moves freely
in the foil pack holder.
6.2 Checking the tool after care and maintenance

ing parts function faultlessly, that no parts are sticking,
broken or damaged and that the tool operates faultlessly.
