Safety regulations
BOMAG 19 MPH 122-2
Any hydraulic oil must be caught and disposed of
in an environmentally friendly manner.
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.
Wear protective clothing.
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
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
range) is used at the right location.
l
hoses are mixed up by mistake.
Working on the engine
Shut the engine down before opening the service
doors.
Do not work on the fuel system while the engine is
running – danger to life due to high pressures!
l
Wait approx. 5 minutes after the engine has
stopped.
l
Keep out of the danger zone during the initial
test rung.
l
In case of leaks return to the workshop imme-
diately.
l
Make sure that the engine cannot be started
unintentionally during service and repair work.
Drain the engine oil at operating temperature –
danger of scalding!
Wipe off spilled oil, catch running out oil and dis-
pose of environmentally.
Store used filters and other oil contaminated ma-
terials in a separate, specially marked container
and dispose of environmentally.
Do not leave any tools or other objects, that could
cause damage, in the engine compartment.
Check and change coolant only when the engine
is cold.
Catch coolant and dispose of environmentally.
Working on electric parts of the machine
Before starting to work on electric parts of the ma-
chine disconnect the battery and cover it with insu-
lating material.
Do not use fuses with higher ampere ratings and
do not repair fuses with a piece of wire. Fire haz-
ard!
Working on the battery
When working on the battery do not smoke, do not
use open fire!
Do not let acid come in contact with hands or
clothes! When injured by acid flush off with clear
water and seek medical advice.
Metal objects (e.g. tools, rings, watch straps) must
not come in contact with the battery poles – dan-
ger of short circuit and burning!
When recharging non-serviceable batteries re-
move all plugs, to avoid the accumulation of explo-
sive gases.
Observe the applicable instructions when starting
with an auxiliary battery.
Dispose of old batteries according to regulations.
Switch off the charging current before removing
the charging clamps.
