Safety regulations
Working on the dozer blade
Lower the dozer blade to the ground and shut the
engine down.
Do not open the grease cartridge on the dozer
blade, after use it will still be pressurized for some
time. In case of damage caustic fluid may run out.
Wash off immediately with lots of clean water.
Cleaning
Do not clean the machine while the engine is
running.
Do not use gasoline or other combustible sub-
stances for cleaning purposes.
When using high pressure steam cleaning equip-
ment do not subject electric components to the
direct water jet or cover them before hand.
Do not guide the cleaning jet into the exhaust pipe.
After maintenance work
Reinstall all protective devices after completing the
maintenance work.
Repair
Attach a warning tag to the steering wheel if the
machine is defective.
In case of welding work on the machine remove the
main battery switch.
Repairs must only be carried out by qualified and
authorized persons. Use our repair instructions.
Test
Depending on the type of applicational and the
operating conditions vibratory equipment has to be
examined by a specialist whenever required, but at
least once every year.

Operation
• Set the control levers 31 and 29 (Fig. 1) to
position "0".
The cold start system is electronically released at
low temperatures. • Check, whether the emergency stop switch 24

the starting process.
• After starting disconnect the minus poles (earth
cable) first and the plus poles last.
Do not drive with full engine speed before the
operating temperature is reached.
At extremely low temperaturesthe hydraulic
oil filter control light in the monitoring board
may light up, but must go out again after
approx. 15 minutes.
When this control light lights up, drive the
machine with half power until it goes out.
Starting with jump leads
For jump starting two external batteries are
required, one for each main battery.
Fig. 7
• When starting with external batteries connect
the plus poles (Fig. 7) and the minus poles
(earth cable) after.
Wrong connection will cause severe damage
to the electrical system.

Maintenance
5.4 Running-in instructions
When taking new machines into operation the
following maintenance work must be per-
formed.
Up to approx. 250 operating hours check the
engine oil level twice every day.
Depending on the engine load the oil consumption
will drop to its normal level after approx. 100 to 250
operating hours.
After a running time of 15 minutes retighten the
V-belts for generator and compressor.
Maintenance after 50 operating hours
• Change the oil in the splitter gear.
• Change the oil in the L + S planetary gears.
• Retighten all screw connections on the ma-
chine.
Maintenance after 500 operating hours
• Change the oil in the splitter gear.
• Change the oil in the L + S planetary gears.
Special intervals
• Run the heating every month for about 10
minutes.
• Run the air conditioning every month for about
10 minutes.
After the installation of new or service ex-
change gearboxes the specified service inter-
vals must be started again from the beginning.

5.31 Checking, adjusting the in-
jection valves and the valve
clearance
Valves and injection valves must be checked and
adjusted at the latest every 1500 operating hours
or once every year.
The tightening torque for the injection valve ad-
justment screws is 0,6 to 0,7 Nm (5 to 6 in-lb).
The valve clearance for Fig. 2

As required
5.45 Cleaning the condenser (air
conditioning unit)
A soiled condenser impairs the efficiency of
the air conditioning system considerably.
Under severe conditions (extreme dust) clean
the condenser several times.
If the warning buzzer sounds continuously
when the air conditioning unit is in operation,
switch the air conditioning unit off and clean Fig. 6
the condenser.
• Keep the drain tube (Fig. 6) for drainage of the
roof empty.
Fig. 5
• Unhook the rubber straps and open the flap 1
(Fig. 5).
• Blow the condenser fins (2) out with pressure
air or clean it with a cold water jet.
Danger of accident!
Do not clean with a hot water jet. Heat causes
an extreme overpressure which can damage
the system or cause explosion of the air con-
ditioning system.
• Straighten deformed fins with a fin comb.
• Close the flap.
