1.5 Safety Instructions for Operation
•
The dynamometer may only be used and operated exclusively for its intended purpose and
only within its performance limits.
•
The dynamometer may only be operated by trained personnel. Dynamometer and working
area must be kept clean.
•
The dynamometer may only be operated by persons who are physically and mentally fit.
These persons should be well rested and not under the influence of alcohol, drugs or medi-
cation.
•
When not in use the system must be switched off and the main switch protected against re-
start.
•
No persons may be in the danger zone of the dynamometer. Rotating or moving parts are
dangerous.
•
Pay close attention to accident prevention regulations.
•
Never climb on roller sets and lifting bar even when locked.
•
Avoid unnecessary strain on vehicle and test stand. Drive the vehicle slowly onto the test
stand.
•
Damage to low lying vehicles is not covered by the warranty.
•
Regularly check the tightness of the cover plate attachment screws.
•
No persons may be in the pit with dynamometers in conjunction with a working pit while a
vehicle with rotating wheels is on the roller set.
•
Wear personal protective clothing. If necessary wear protective goggles. Particles ejected
from rotating vehicle wheels can cause severe injuries. Wear tightly fitting working clothes
and bind long hair together. Clothing or hair can get caught and pulled into machinery.
•
Danger of hearing damage due to high noise level! Use hearing protection approved up to
120 dB(A). Noise levels over 110 dB(A) can be reached during vehicle testing. The operator
is responsible for determining the noise level in vehicle and test room. When necessary, wear
suitable hearing protection. The operator must attach warning stickers.
•
Danger of carbon monoxide poisoning by poisonous vehicle exhaust. The test stand may on-
ly be operated if the room in which the test stand is installed has sufficient exhaust suction
and ventilation including the appropriate warning system.
•
Avoid steering movement during the vehicle test. These cause certain forces to act on the
vehicle fixing in particular on the attachment units on the test vehicle. Vehicle doors and
windows must be closed during the test drive.
•
Before exiting the vehicle, put the vehicle into idle and/or put the gear to NEUTRAL. If neces-
sary decelerate the vehicle in a controlled manner avoiding steering movements. Wait until
vehicle and rollers have stopped moving before exiting the vehicle. Danger of body parts and
clothing being pulled into rotating rollers and vehicle wheels.
•
Keep dyno surface clean and dry. Danger of slipping when surface is wet, oily or icy! Do not
place any objects (tools, material etc.) on the dynamometer. Wear protective shoes with anti-
slip soles and steel toe caps to avoid slipping and mechanical injuries. Parts which protrude
more than 20 mm out of the floor are to be marked with black-yellow tape.
•
In addition to the danger zone, the operator is responsible for confining the area of the test
room in which no persons are allowed during testing with a safety catch device or a cell wall.
Mark the danger zone (roller width + 1100 mm) on both sides behind the vehicle up to cell
wall/safety catch device.
•
Danger of accident due to vehicle fixing fracturing! Do a visual check for damage to the vehi-
cle fixing before each use. Never start the test operation without suitable and correctly in-
stalled vehicle fixing. Lower lifting bar before fixing the vehicle. Fix the test vehicle at the
back and front side to the dynamometer and secure against lateral break out and swinging
movements. The vehicle fixing must be adjusted to the vehicle being tested and may only be
