6 SAFETY INFORMATION FOR BATTERY-OPERATED CLEANING MACHINES
Rechargeable lithium batteries require special care and caution to minimise risks and extend durability of battery. Improper use of recharge-
able batteries and failure to observe safety notes and instructions can cause personal injuries and damage to the machine. The WETROK AG
cannot be made liable for any damage resulting from improper use and disregard of safety notes and instructions. Claims under warranty are
voided if these instructions are disregarded. In principle, the warranty period is 1 year. Please read the conditions and notes carefully before
using the rechargeable battery.
Safety notes (rechargeable battery):
• Keep rechargeable battery away from any source of heat (i.e. fire, glowing objects, radiators, direct sunlight). Extreme heat can result in
an explosion of the rechargeable battery. Ensure sufficient ventilation while recharging battery. High temperatures reduce the service
life of the rechargeable battery.
• Recharge Li-ion battery only at ambient temperatures ranging between 5°C and 40°C (35°F-104°F). Do not recharge battery at
temperatures below 0°C and above 50°C.
• The rechargeable battery must not be damaged mechanically. Dents or holes on/in the rechargeable battery can cause a complete
breakdown of the battery and may result in a fire / explosion. Never recharge or use a damaged rechargeable battery.
• Rechargeable Li-ion rechargeable batteries contain chemical substances. Not to be taken internally! Avoid contact with skin and eyes.
• Never open or destroy casing cover of rechargeable battery. Do not connect cables, connectors or others to the terminal plug of the
rechargeable battery. This can cause short circuits and will result in a destruction of the rechargeable battery.
• No modifications to the wires are permitted! In particular, do not remove or open any electrical terminals or remove the earth cable!
Do not operate appliances with damaged cables!
Handling and storage:
• Recharge the battery completely prior to first use.
• Use the charger provided for recharging battery only. The use of another charger can cause malfunctions, reduce battery life and/or
lead to fire and explosions.
• Regular operation reduces battery life faster than partial charging due to constant complete discharging. Therefore, always recharge
battery after short periods of use.
• Do not store machine uncharged over a longer period (max. 1 month). When machine needs to be stored for a longer period, recharge
battery regularly to ensure it is NEVER COMPLETELY DISCHARGED and equally NEVER COMPLETELY CHARGED. The rechargeable
battery stores best when charged to 70% of its charging capacity. This is reached by recharging battery COMPLETELY first.
Then operate the machine for about 25 minutes in scrubbing-suction mode. The ideal long-term storage temperature is 10°C.
• It is permissible to use and store machine within an operating temperature range of 5°C to 40°C only.
• Do not clean machine with high-pressure or steam-pressure cleaners or liquid spray. Prevent direct contact with water.
• Only charge the rechargeable battery in dry conditions. Ensure the charging plug does not come into contact with water.
• Only use Wetrok rechargeable batteries; item number 55999.
