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:
the outer layer is damaged down to the inlay
l
(e.g. chafing, cuts, cracks)
the outer layer is brittle (formation of cracks in
l
the hose material)
the hose shows deformations in pressurized
l
and depressurized condition, which do not
comply with the genuine shape of the hydrau-
lic hose
the hose shows deformations in bends, e.g.
l
squeezing, buckling, layer separation, forma-
tion of blisters
parts of the hose are leaking.
l
hoses are not correctly installed.
l
the hydraulic hose has separated from the fit-
l
ting
the fitting shows corrosion that impairs both
l
function and strength.
hoses are mixed up by mistake.
l
fittings are damaged or deformed, whereby
l
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.
Working on the engine
Shut the engine down before opening the engine
hood.
Do not work on the fuel system while the engine is
running - danger to life due to high pressures!
Wait another minute after the engine has
l
stopped.
Keep out of the danger zone during the initial
l
test rung.
In case of leaks return to the workshop imme-
l
diately.
Make sure that the engine cannot be started
l
unintentionally during service and repair work.
BW 213 D-4
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.
The settings for idle speed and highest speed
must not be changed, since this would affect the
exhaust gas values and cause damage to engine
and power train.
Turbo chargers work with high speeds and high
temperatures. Keep hands, tools and materials
away from the intake and outlet openings of the
nturbo charger and do not touch any hot surfaces.
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!
Disconnect the battery before starting welding
work on the machine.
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 serviceable batteries remove all
plugs, to avoid the accumulation of explosive gas-
es.
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.
