Changing RRC1 batteries:
When approximately 10% of battery capacity remains, the top LED lights red.
- Remove the back of the radio control by unscrewing the 5 screws.
- Replace the 2 x 1.5V AAA batteries with the correct polarity.
Use alkaline batteries for optimal performance.
- Screw the back of the radio control into place.
BATTERY PRECAUTIONS
As batteries contain fl ammable substances such as lithium or other organic
solvents, they may cause heating, rupture or ignition.
WARNING! Do not recharge the batteries. Attempts to recharge may cause rupture or hazard-
ous liquids to leak, which will corrode the equipment.
NOTE: Electronics and batteries must be physically separated before disposal.
Make sure that electronics or batteries are not disposed of in household waste.
- There is a risk of explosion if a battery is replaced with the incorrect type of battery.
- Do not short circuit, disassemble, deform or heat batteries.
- Keep batteries out of reach of children. If a child swallows a battery, seek immediate medical at-
tention.
- When discarding batteries, insulate the + and - terminals of batteries with insulating/masking
tape. Do not put multiple batteries into the same plastic bag.
- When improperly disposed, batteries may short circuit, causing them to become hot, burst or
ignite.
- Store in a cool place. Keep batteries away from direct sunlight, high temperatures, and high
humidity. Do not throw batteries onto fi re.
3. INSULATED FLEXIBLE HOSE
High pressure fl exible hoses are subject to a natural ageing process which can result
in a reduction in performance potentially aff ecting safety of the operator. As a result
their life span is limited. In order to ensure safe use of their units, Cembre recommends
replacing the hose within 10 years from the date printed on the fi ttings.
- Before using the pump always check the integrity of the fl exible hose and the quick couplers
making sure there are no abrasions, cuts, deformations or swellings.
- Keep the fl exible hose away from naked fl ames and sources of heat above 158°F (70°C).
- The factory fi tted guards must be in place at each end of the fl exible hose.
- Do not touch the fl exible hose when under pressure.
- When using the pump, the fl exible hose must be uncoiled and laid out straight.
The standard fl exible hose is 33 ft (10 m) long. It is used to deliver oil under pressure, generated
by the pump, to the cutting head and as an insulating element between the head and the pump.
The insulated fl exible hose is completely fi lled with an insulating oil with dielectric properties
which insulate the pump from the cutting head
The working range of the cutting head is 33 ft from the pump; this distance allows the
proper communication between the head and the pump.
In case longer insulated fl exible hoses are used and the pump is kept outside of the
manhole, it is possible that the wireless blade travel sensor signal will not reach the pump.
