Service
▶
Have your power tool serviced by a qualified repair person using only identical replacement parts.
This will ensure that the safety of the power tool is maintained.
▶
Never service damaged battery packs. Service of battery packs should only be performed by the
manufacturer or authorized service providers.
2.2 Additional safety instructions for crimping tools
Personal safety
▶
Use the product only when it is in perfect working order.
▶
Never tamper with or modify the power tool in any way.
▶
Never carry out crimping work on parts of a gas supply network unless express approval has been given
by the system supplier for use of this tool in conjunction with specially tested and approved fittings.
▶
Check that the locking pin is pushed in all the way and securely engaged.
▶
To avoid pinning or trapping the fingers, after inserting the crimping jaws/adapter jaws position the
tubular guard so that the gap between crimping jaws/adapter jaws and holder (crimping head) is as small
as possible.
▶
Make sure that there are no foreign objects (e.g. plaster, grit particles, metal cuttings, etc.) in the crimping
jaws and no parts are damaged. Do not continue to use damaged or distorted crimping jaws!
▶
Always use the grip for carrying the device and always make sure your hands are dry. If your fingers/hands
are oily or greasy you might lose your grip on the device and drop it.
▶
Before starting work, check the crimping tool and NPR PS crimping jaws or, as applicable, NPR
PR crimping rings in accordance with the instructions. Inadequately tested tools, jaws or rings can
lead to substandard crimpings and are a potential safety risk for the operator. Crimping tools must
undergo inspection by Hilti service at the latest every 15,000 crimping operations and at least once a
year. Crimping jaws and rings must undergo servicing by Hilti service at least once a year.
▶
After crimping, pressure-test the tubing system to ensure that it is free of leaks (resulting from misuse of
the tool, for example).
Electrical safety
▶
Before use of the power tool, all live cables or other items carrying electric voltage within the area in which
the user is working are to be switched off. If this is not possible, the corresponding safety precautions
for working in the proximity of live cables or equipment must be implemented and observed.
▶
Do not crimp live parts. The tool must be considered to be uninsulated and must therefore be used
in conjunction with personal protective equipment (protective gloves, protective footwear, protective
clothing, etc.) of a type suitable to provide protection for yourself and other persons in the vicinity.
Power tool use and care
▶
After approx. 50 consecutive crimping operations, switch the power tool off and allow it to cool down for
about 15 minutes. Overheating can lead to damage to the power tool.
2.3 Battery use and care
▶
Observe the special regulations and instructions applicable to the transport, storage and use of Li-ion
batteries.
▶
Do not expose batteries to high temperatures, direct sunlight or fire.
▶
Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C.
▶
Do not use or charge batteries that have suffered mechanical impact, have been dropped from a height
or show signs of damage. In this case, always contact your Hilti Service .
▶
If the battery is too hot to touch it may be defective. In this case, place the product in a non-flammable
location, well away from flammable materials, where it can be kept under observation and allowed to
cool down. In this case, always contact your Hilti Service .
