Preparational safety
WARNING! CAUTION WHILE TRANSPORTING AND LIFTING
Risk of crushing from falling objects.
•Use the lifting handles on the saw head or place it in the transport trolley for
safe handling. Make sure the machine modules are secured to the transport
trolley and that the transport trolley is placed on a stable, flat surface. If placed
on a slope or uneven surface, instability may occur and it can fall or roll away.

equipment when necessary.
•If the machine needs to be lifted with a crane, this can only be done after
permission and instructions have been given by a person responsible for safety
on the site.
•For lifting and transportation of the machine in the transport trolley, see 3.2.
BEFORE MOUNTING AND USING
Fatal injury may be caused by sudden machine start-up. Risk of electric shock from
live cables and connectors. Uncontrolled movements of the saw may result in injury
or death.
•Before any kind of service or mounting of, or on the machine is commenced,

power supply.

Operator’s manual Pentruder RS2 wall saw and Pentpak 3 HFi power pack – Original instructions Page 10
WARNING!
If the machine does not stop running after an accident it may result in fatal injury.
Uncontrolled movements of the saw may result in injury, death, and material
damage. Cutting in a power line may result in serious injury or sudden death.
Before cutting is commenced, make sure:
•there are no power lines, gas pipes or other piping which can be damaged or
cut off by the saw blade.
•the statics of the building are not compromised because of the cut openings.
•no damage is done on the other side of the concrete when cutting through.
•you check with a person responsible for site safety that all necessary
precautions have been performed before commencing work and await the
approval of the safety precautions and mounting position of the machine
before work is commenced.
•to not commence any work which cannot be judged safe. Always use common
sense and best working practice.
•all persons involved know where the emergency stop button is located and
how it works.
•that the emergency stop button can be reached quickly.
•there is always sufficient lighting and visibility.
WARNING!
Before cutting is commenced, make sure the saw blade rotational speed is correctly
set. Do NOT start at and/or cut at a too high speed. See 3.10 “How to choose
correct cutting speed”.
WARNING! WEAR SAFETY EQUIPMENT
Risk of cut from saw blade, crushing injuries, permanent hearing disorders and
chronic respiratory problems. Risk of frostbite in cold temperatures or burn injuries
from hot parts.
•All persons working with, or in the proximity of the machine must wear safety
equipment, i.e., safety helmet, safety shoes, safety gloves, safety glasses and
hearing protection. Note that protective equipment does not provide complete
