clean and free of oil and grease.
15 Pull the plug from the socket. When not using the electric tool, before maintenance or
when changing tools, such as saw blades, drills and cutting bits.
16 Do not leave any tool keys inserted. Before switching on, check to see that keys and
adjustment tools have been removed.
17 Avoid unintentional activation. When plugging the tool in, make sure that the switch is
turned off.
18 Use outdoor extension cords. When outdoors, use only extension cords that are approved
and appropriately marked.
19 Be alert. Pay attention to what you do. Approach your work sensibly. Do not use the electric
tool when you are distracted.
20 Check the electric tool for damage. Before using the electric tool, you must inspect safety
equipment or slightly damaged parts carefully to ensure that they work properly and as in-
tended. Check to see that the moving parts operate freely and don’t stick, and to make sure
no parts are damaged. All parts must be mounted properly and meet all the conditions for
ensuring trouble-free operation of the electric tool.
Damaged safety equipment and parts must be properly repaired or replaced by a professional
facility, unless otherwise indicated in the user manual. Damaged switches must be replaced
by a customer service facility.
Never use an electric tool whose switch cannot be turned on and off.
21 Caution. Using other insertion tools and accessories may cause injury.
22 Have your tool repaired by an electrical expert. This electric tool meets applicable safety
requirements. Repairs must be made only by an electrical expert using original replacement
parts. Otherwise accidents many occur.
1.2 Special safety instructions
- Only guide the spirals using a suitable riveting glove (model no. 72120 on the left; model no.
72121 on the right). Do not continue to use a damaged rivet glove. (A rivet glove is not perso-
nal safety equipment according to 89/686/EWG - see also 6.6)
- When using the rivet glove, make absolutely sure also to wear a disposable latex glove under
the rivet glove for hygienic reasons. (Do not continue using a damaged latex glove.)
- Wear rubber boots (for insulation) when performing cleaning work.
- The spirals must be removed completely from the holding cage before machine is turned on.
- Before inserting the plug into the electrical socket, make absolutely sure that the pipe cleaning
machine is switched to 0 or OFF.
- Whenever using electrical devices, always observe the specified voltage and generally work with
a protective tube and safety gloves.
- Choose the right tool for the clog and for the pipe diameter to be cleaned, in order to prevent
the tool from hooking into the clog and the spiral from ejecting from the pipe.
- To prevent damage, use this machine and its accessories only to clean waste water pipes — ne-
ver chimneys, wells, etc.
- To prevent damage to the pipes or pipe bends, do not modify tools by whetting them, etc.
- Use a camera system to spot the cause of the pipe clog.
1.3 Residual risks
Even when observing all of the safety instructions there are still some residual risks remaining, for
example: spirals can overturn (create a loop if the operating arc is too large) thereby creating the
risk of clamping. Spirals under tension can spring out of the pipe
~ a risk of injury.
