Exhaust gases are highly dangerous! Always en-
sure an adequate supply of fresh air when starting
in closed rooms!
Driving the machine
Persons in the danger area
Before taking up work, also after breaks, you
should always convince yourself that the danger
zone is free of persons or obstructions, especially
when driving in reverse.
Give warning signals, if necessary. Stop work im-
mediately if persons remain in the danger zone,
despite the warning.
Do not step or stand in the articulation area of the
machine when the engine is running. Danger of
squashing!
Driving
In events of emergency and in case of danger ac-
tuate the emergency stop switch immediately. Do
not use the emergency stop switch as service
brake.
Restart the machine only after the danger that
caused the actuation of the emergency stop switch
has been eliminated.
If the machine has contacted high-voltage power
lines:
l do not leave the operator’s stand
l warn others from coming close to or touching
the machine
l if possible drive the machine out of the danger
zone
l have the power switched off

gradability of the machine.

17. Safety regulations
BOMAG 17
BW 141/151 AD-4/BW 151 AC-4
On slopes drive extremely careful and always di-
rectly up or down the slope. Change to a lower
gear before starting to drive.
Wet and loose soils considerably reduce the
ground adhesion of the machine on inclinations
and slopes. Higher risk of accident!
Behaviour in traffic
Match the speed to the working conditions.
Always give way to loaded transport vehicles.
Switch the lights on if the visibility is poor.
Keep away from edges and embankments.
Checking the effect of vibration
When compacting with vibration you must check
the effect on nearby buildings and underground
supply lines (gas, water, sewage, electric power),
if necessary stop compaction work with vibration.
Do not activate the vibration on hard (frozen, con-
crete) ground. Danger of bearing damage!

clearly visible sign.
Parking on slopes and inclinations
Secure the machine against rolling, place metal
chocks in front of and behind the wheels.
Filling in fuel
Do not inhale any fuel fumes.
Refuel only with the engine stopped and the auxil-
iary heater switched off.
Always use access steps.
Do not refuel in closed rooms.
No open fire, do not smoke.
Do not spill any fuel. Catch running out fuel, do not
let it seep into the ground.
Wipe off spilled fuel. Keep dirt and water away
from the fuel.
A leaking fuel tank can cause an explosion. En-
sure tight fit of the fuel tank cover, if necessary re-
place immediately.
Fire protection measures
Familiarise yourself with the location and the oper-
ation of fire fighting equipment. Observe all fire re-
porting and fire fighting possibilities.

chine.
Do not perform maintenance work while the ma-
chine is driving or the engine is running.
Park the machine on horizontal, level, firm ground.
Pull the key out of the ignition switch.
pull the key off the main battery switch.
Work on hydraulic lines
Relieve hydraulic pressures before working on hy-
draulic lines. Hydraulic oil escaping under pres-
sure can penetrate the skin and cause severe
injury. When being injured by hydraulic oil consult
a medical doctor immediately, as otherwise this
may cause severe infections.
Do not step in front of or behind the drums/wheels
when performing adjustment work in the hydraulic
system.

Catch running out hydraulic oil and dispose of en-
vironmentally.
Always catch and dispose of hydraulic oils sepa-
rately.
Do not start the engine after draining the hydraulic
oil.
Once all work is completed (with the system still
depressurized!) check all connections and fittings
for leaks.
Changing hydraulic hoses
Hydraulic hoses must be visually inspected at reg-
ular intervals.
Hydraulic hoses must be immediately replaced if:
l the outer layer is damaged down to the inlay
(e.g. chafing, cuts, cracks)
l the outer layer is brittle (formation of cracks in
the hose material)
l the hose shows deformations in pressurized
and depressurized condition, which do not
comply with the genuine shape of the hydrau-
lic hose
l the hose shows deformations in bends, e.g.
squeezing, buckling, layer separation, forma-
tion of blisters
l parts of the hose are leaking.
l hoses are not correctly installed.
l the hydraulic hose has separated from the fit-
ting
l the fitting shows corrosion that impairs both
function and strength.
l hoses are mixed up by mistake.
l fittings are damaged or deformed, whereby
the function and strength of the hose/hose
connection is impaired.
Only genuine BOMAG replacement hydraulic hos-
es ensure that the correct hose type (pressure
