To reduce the risk of injury, the user must read and understand the instruction
manual.
The unit has been designed with the benefit of the most up-to-date technology and
to recognised safety regulations, and is safe to operate. However, if it is used incor-
rectly or for a purpose for which it was not intended, risks to the user or to third
parties or damage to property may result. For this reason, read and comply with the
safety instructions!
KEEP ALL SAFETY NOTES AND INSTRUCTIONS FOR THE FUTURE.
General Safety Instructions
WARNING
● Only use the unit for the purpose for which it was intended, with due attention to
the general safety and accident prevention regulations.
● Only allow trained personnel to use it. Apprentices may only operate the unit
when they are older than 16, when this is necessary for their training, and under
the supervision of a trained operative.
● Keep the work area tidy. Clutter can prove dangerous.
● Avoid dangerous ambient influences (e.g. inflammable fluids or gases).
● Provide adequate lighting at the workplace.
● Wear tight work clothes, keep long hair well clear, take off jewellery and similar.
● Use personal safety equipment (safety glasses).
● Keep bystanders away, especially children.
● Take up a firm standing position during operation.
● Do not overload the unit.
● Check the unit occasionally for damage, and to see that it is operating correctly.
● Replace worn parts as early as possible.
● Only use genuine spare parts and accessories, for personal safety reasons, to
ensure correct operation of the unit, and to preserve the basis for warranty claim.
● All unauthorised modifications of the unit are prohibited for safety reasons.
● All repair work must be performed only by specialist personnel or by persons
familiar with the unit.
Specific Safety Instructions
WARNING
● The ROLLER'S pressurised water canister meets the requirements of the EC
Directive 97/23.
● Always watch the piston pressure gauge during pumping in order not to exceed
the max. spray pressure. Fully relieve the remaining pressure in the tank before
filling, after use and before maintenance.
● The safety valve should not be deactivated.
● Pull up the red button of the piston pressure gauge until there is no pressure in
the tank.
● Do not exceed the filling capacity of 10 l.
● Do not exceed the operating temperature of pressurised canisters of max. 40°C.
Do not expose canisters to intense sunshine.
● Store the pressurised water vessel safe from frost.
● Check the pressurised water canister for damage (dents, tears). Do not repair
damaged canisters.

WARNING
ROLLER'S pressurised water canister is intended for the purpose of wet drilling with
the electric diamond core drilling machines ROLLER'S Centro S1, ROLLER'S Centro
S3, ROLLER'S Centro SR and ROLLER'S Centro S2/3.5.
All other uses are not for the intended purpose and are prohibited.

2. Commissioning and operation
Water can be supplied through the diamond core drilling crown with the
ROLLER'S pressurised water canister as an alternative to the water mains. To
prepare the pressurised water canister, screw the enclosed hose pipe to the
connection on the bottom of the canister and tighten by hand. Then press down
the pump handle, turn it to the left and unscrew the pump. Fill the canister with
a max. 10 l of water and screw the pump back in. Close the shut-off valve (5)
of the water supply device (3) of ROLLER'S Centro S1, ROLLER'S Centro S3,
ROLLER'S Centro S2/3.5 or ROLLER'S Centro SR. Remove the coupling
socket (4) of the water supply device (3) and connect the water supply device
to the coupling (2) of the pressurised water canister. Pump up the canister by
repeatedly pumping the handle. The pressure created in the canister can be
read on the safety valve (Fig. 1.1 / red knob). The safety valve limits the working
pressure to max. 3 bar. If the pressure in canister continues to rise, the safety
valve blows off pressure. Withdrawal of water is regulated by slowly opening
the shut-off valve (5). The pressure in the canister drops when water is drawn
off and has to be pumped back up. Before refilling the canister with water, the
red knob on the safety valve must be lifted to blow off the remaining pressure.
CAUTION
A defective safety valve must be replaced immediately!
3. Maintenance
After using 50 times, at least once a year.
● Unsrew the pump (6) from the tank (Fig. 2).
● Dismantle the pump (6) and grease the sleeve (8) (Fig. 3 and 4).
● Grease the O-ring (7) (Fig. 5).
4. Faults
4.1. Fault: No pressure builds up in the device.
Cause:
● Pump not screwed tight.
● O-ring (7) on the pump defective
(Fig. 5).
● Sleeve (9) defective (Fig. 5).
4.2. Fault: Liquid escapes from the pump.
Cause:
● Valve disk (10) soiled or
defective (Fig. 6).
4.3. Fault: Piston pressure gauge indicates no tank pressure,
safety valve blows off too early.
Cause:
● Piston pressure gauge (11)
defective (Fig. 7).
