• Place the wiping leather on it.
• Fix the wiping leather with the top of the wipe head adapter.

4.3 Connecting the power drill

WARNING!
If the brush suddenly becomes blocked, there is a risk the power drill will be ripped violently out of your hands. Consequently, we recommend to use a power drill with a torque clutch.

• Insert the power drill connector of the rotary viper into the drill chuck. Observe the instructions in the operating manual belonging to the power drill and obey the safety instructions in particular.

Using the rotary viper

• Before using, unroll the rotary viper fully.
• Power on the power drill to make the cleaning attachments rotate.

ATTENTION!
The rotary viper must only rotate clockwise. If it rotates anticlockwise, there is a risk the attached brush will work loose.
Clockwise direction of rotation: Max. 1 300 rpm with cleaning attachment Anticlockwise direction of rotation: Max. 650 rpm with brush head
ATTENTION!
Friction will cause the temperature of the sheath to rise if the rotary viper is used for longer periods of time. Ensure the specified operating temperature of 80°C is not exceeded, otherwise the sheath of the rotary viper will be damaged.
ATTENTION!
Do not tread on the rotary viper when it is in use. Do not allow it to strike against the floor. That could damage the sheath of the rotary viper and degrade its anti-friction properties.
ATTENTION!
Avoid overloading: If the cleaning attachment can no longer rotate in a pipe, stop the rotary viper rotating and push it through the pipe to be cleaned without any rotation. Rotate the cleaning attachment of the rotary viper first when you  are pulling it back.

Maintenance

The Wohler rotary viper M 5 requires very little maintenance. The bearings in the end pieces are self-lubricating. The core is sufficiently greased with high-quality graphite lubricant.
After it has been in use for a long time it is possible that the grease in the core will need to be replenished. This will become noticeable by the protective PA sheath becoming unusually warm. It should be returned to the factory for the grease to be replenished.

Guaranty and Service

7.1 Guaranty
Each Wohler Rotary Viper M 5 will be tested in all functions and will leave our factory only after extensive quality control testing.
If used properly, the warranty period for the Wohler Rotary Viper will be 12 month from the date of sale.
Not covered by the warranty are cleaning attachments (brush head made of Perlon or threaded brush), because they are consumables.
This warranty does not cover the freight and packing costs when the device is sent to  the factory for repair.
Service by non authorized personnel or making modifications to the analyzer voids any warranty.
7.2 Service

• When you send your meter to us, we will repair it within a few days and return it via our trusted parcel carrier.
