Behaviour In The Event Of Faults - REMS Nano Betriebsanleitung

3.2. Supporting the Material
CAUTION CAUTION
Always support pipes and longer pipe sections, on both sides if necessary, e.g.
with height-adjustable REMS Herkules 3B or REMS Herkules Y material rests
(accessory, Art. No. 120120 or 120130). Make sure that the height-adjustable
material rest is set to the same height of the pipe rest (6). This reduces untrue
running and uncontrolled falling of the pipe to the ground.
3.3. Low Discharge Protection
REMS Akku-Nano is equipped with low discharge protection for the battery.
This switches off the power tool as soon as the battery needs to be recharged.
In this case remove the battery and charge with the REMS rapid charger.
4. Maintenance
Notwithstanding the maintenance described below, it is recommended to send
in the power tool to an authorised REMS contract customer service workshop
for inspection and periodic testing of electrical devices at least once a year. In
Germany, such periodic testing of electrical devices should be performed in
accordance with DIN VDE 0701-0702 and also prescribed for mobile electrical
equipment according to the accident prevention rules DGUV, regulation 3
"Electrical Systems and Equipment". In addition, the respective national safety
provisions, rules and regulations valid for the application site must be considered
and observed.

4.1. Servicing
WARNING
Pull out the mains plug or remove the battery before maintenance work!
Keep the rollers of the pipe rest (6), cutting wheel (4) and cutting wheel holder
clean. Clean heavily soiled metal parts with the REMS CleanM machine cleaner
(Art. No. 140119) and then protect against rust.
Clean plastic parts (e.g. housing) only with REMS CleanM machine cleaner
(Art. No. 140119) or a mild soap and a damp cloth. Do not use household
cleaners. These often contain chemicals which can damage the plastic parts.
Never use petrol, turpentine, thinner or similar products for cleaning.
Make sure that liquids never get onto or inside the power tool. Never immerse
the power tool in liquid.
4.2. Inspection/Repair
WARNING
Before any repair work, pull the mains plug or remove the battery! This
work may only be performed by qualifi ed personnel.
The gear REMS Nano, REMS Akku-Nano runs in a life-long grease fi lling and
therefore needs no lubrication. The motors of REMS Nano and REMS Akku-
Nano have carbon brushes. These are subject to wear and must therefore be
checked by qualifi ed specialists or an authorised REMS customer service
workshop from time to time. The carbon brushes cannot be replaced so that
the motor may have to be changed. See also page 5. Behaviour in the event
