General Power Tool Safety Warnings
WARNING
WARNING
Read before use!
To reduce the risk of injury, the user must read and understand the instruction
manual.
The device has been built and operates safely in accordance with the state of the
art and the recognised rules of safety. Nevertheless dangers for the user or third
parties or material damage may arise from improper use or use not for the intended
purpose. Therefore read and follow the safety instructions!
Keep all safety rules and instructions for the future.
Only use the device for the intended purpose and under observance of the general
safety and accident prevention regulations.
A) Work place
● Keep the work place tidy. Untidiness can cause accidents.
● Avoid dangerous ambient infl uences (e.g. infl ammable liquids or gases).
● Keep children and other persons away when using the device. Distractions can
lead to you losing control of the tool.
● Make sure that the work place is well lit.
● Make sure you are standing safely during work.
● All unauthorised modifi cations to the device are prohibited for safety reasons.
● Change worn parts immediately.
● Never let ROLLER'S Polar operate unattended.
B) Safety of persons
● Only employ trained personnel. Youths may only operate the device if they are
over 16 years of age, it is essential to achieve their training goal and they are
supervised by a specialist.
● Wear tightly fi tting clothing, tie loosely hanging hair, take off jewellery and similar.
● Use personal safety equipment (protective glasses, gloves).
● Only use genuine accessories and spare parts for your own safety, to assure
proper functioning of the device and to uphold your warranty rights.

● Only work in a well aired environment. CO
heavier than air. It therefore gathers near the fl oor and displaces the air if there
is no adequate ventilation. Danger of suffocation!
WARNING
WARNING
● Work with naked fl ames may not be carried out closer than 60 cm from the
freezing point.
● Do not hit freezed collars with tools (danger of breakage).
● Keep other persons and especially children, also animals away. Dry ice causes
burns in contact with the skin. Do not dispose of residue ice from collars care-
lessly at the end of work but throw it in the waste bin.

● Pressurised gas cylinders should only be transported with cylinder trolleys or in
case of small cylinders in suitable cariers or in the cylinder pallet. Do not hang
pressurised gas cylinders to a crane by the valve protection (e.g. protective cap
or cage) for transport. The valve protection devices are designed exclusively for
protection of the valve and may not be used for lifting with a crane or lifting devices
(e.g. chains).
● Lifting and carrying the gas cylinder by the cylinder valve or connected fi ttings is
not permissible.
● Pay attention to adequate ventilation when transporting gas cylinders in a closed
vehicle.

● A risk assessment must be made before emptying pressurised gas cylinders.
● Pressurised gas cylinders connected for emptying must always be secured against
falling over.
● Before emptying pressurised gas cylinders, it must be ensured that the gas cannot
fl ow back into the pressurised gas cylinders from the pipe system.
● Gas cylinders may only be stored in well-aired areas.
● It is not permissible to leave gas cylinders in a closed, unventilated vehicle.

WARNING
WARNING
ROLLER'S Polar is intended for freezing unemptied pipes with carbon dioxide (CO
refrigerant.
All other uses are not for the intended purpose and are therefore prohibited.
1.1. Scope of Supply
Pipe freezer, 2 freeze collars each Ø ⅛" – 2", Ø 10–60 mm (10 sizes), bottle
connection with T-distributor, closing nut, 2 handle pieces with injector nozzle,
2 high-pressure hoses, operating instructions, plastic case.
1.2. Working range
Steel, copper, plastic, composite pipes
The ice pack which forms in the pipe is capable of withstanding a pressure of
approx. 500 bar.

2. Preparations for Use
Remove the seal from the CO
cylinder valve (right-hand thread). Screw high-pressure hoses to the T-distrib-
utor. Screw on the handle piece with injector nozzle to the high-pressure hoses
(Fig. 1). Choose freeze collars which correspond to the size of the pipe to be
frozen. Place the freeze collars on the pipe and secure by tightening the screws
evenly to give a fi rm but not overtight hold (Fig. 2). Turn and, at the same time,
push each handle piece with injector nozzle into the bore of the freeze collar
until it is completely inserted and resting against the stop (Fig. 3).
