e.g. road surface layers.
Unintended use
Dangers may arise from the machine when it is
used for purposes other than the one it is intended
for.
Any danger caused by intended use is the sole responsibility of the customer or driver/operator, the
manufacturer cannot be made liable.
Examples for unintended use are:
l work with vibration on hard concrete, cured bi-
tumen layers or extremely frozen ground
l driving on unstable subbases or too small con-
tact area (danger of tipping over)
l using the machine for towing
l use to pull down walls or demolish buildings
Transporting persons, except the machine driver,
is prohibited.
Starting and operation of the machine in explosive
environments and in underground mining is prohibited.
Remaining dangers, remaining risks
Despite careful work and compliance with standards and regulations it cannot be ruled out that further dangers may arise when working with and
handling the machine.
Both the machine as well as all other system components comply with the currently valid safety regulations. Nevertheless, remaining risks cannot be
ruled out completely, even when using the machine for the purpose it is intended for and following all information given in the operating
instructions.
A remaining risk can also not be excluded beyond
the actual danger zone of the machine. Persons
remaining in this area must pay particular attention
to the machine, so that they can react immediately
in case of a possible malfunction, an incident or
failure etc.
All persons remaining ion the area of the machine
must be informed about the dangers that arise
from the operation of the machine.

Safety regulations
BOMAG16 BW 177 D-4
Checking the Roll Over Protective
Structure (ROPS)
Note
i
On machines with cab the ROPS is an integral part
of the cab.
The frame of the machine must not be warped,
bent or cracked in the area of the ROPS fastening.
The ROPS must not show any rust, damage, hairline cracks or open fractures.
The actual weight of the machine must not exceed
the testing weight of the ROPS.
The ROPS must not rattle about when driving.
This indicates that it is not properly fastened. All
bolted connections must comply with the specifications and should be absolutely tight (observe
the tightening torques). Screw and nuts must not
be damaged, bent or deformed.
With the cab assembled check also the state of the
cabin mounts (rubber elements and screws).
No accessories may be welded or bolted on and
no additional holes must be drilled without the consent of the manufacturer, since this will impair the
strength of the unit.
The ROPS must therefore also not be straightened or repaired if it is damaged.
A defect ROPS must generally be replaced with an
original spare part in close coordination with the
manufacturer.
Starting the machine
Before starting
Operation of the machine is only permitted when
sitting in the operator's seat.
Use only machines which have been properly
serviced at regular intervals.
Become acquainted with the equipment, the control elements, the working mode of the machine
and the area you will be working in.
Use your personal protective outfit (hard hat, safety boots etc.).
Check before mounting the machine if:
l there are persons or obstructions beside or
under the machine
l the machine is free of any oily and combustible
material
l all handrails, steps and platforms are free of
grease, oils, fuels, dirt, snow and ice
l the engine compartment hood is closed and
locked
To climb onto the machine use steps and handrails.
Check before starting, whether:
l the machine shows any obvious defects
l all protective devices are properly secured in
their place
l steering, brakes, control elements, lighting
and warning horn are in order
l the seat is correctly adjusted
l the mirrors (if available) are clean and correct-
ly adjusted.
Do not start the machine if any gauges, control
lights or controls are defective.
Do not take any loose objects with you or fasten
them to the machine.
On machines with ROPS you should always wear
your seat belt!
Starting
Start and operate the machine only from the operator's seat
For starting set all control levers to "neutral position".
Do not use any starting aids such as Start Pilot or
ether.
After starting check all gauges.
Starting with jump leads
Connect plus with plus and minus with minus
(ground cable) - always connect the ground cable
last and disconnect it first! Wrong connections
may cause severe damage in the electric system.
Never start the engine by bridging the electrical
connections on the starter, because the machine
would probably start to move immediately.
Starting in closed rooms
Exhaust gases are toxic! Always ensure an adequate supply of fresh air when starting in closed
rooms!
Safety regulations
BOMAG 17BW 177 D-4
Driving the machine
Persons in the danger area
If a machine has turned over and the cabin door is
jammed, the right hand cabin window can be used
as an escape door.
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 immediately 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
Always wear the seat belt when driving.
Do not drive on bases with insufficient load bearing capacity.
Do not drive on ice and snow.
In events of emergency and in case of danger actuate 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.
Operate the machine only from the operator’s
stand.
Keep the cabin doors closed.
Do not adjust the driver’s seat while driving.
Do not climb onto or off the machine while the machine is driving.
Change the travel direction only at standstill.
Do not use the machine to transport persons.
In case of unusual noises and development of
smoke perform trouble shooting and have the fault
corrected.
Always keep a sufficient distance to excavation
walls and embankments and do not use working
methods that could impair the stability of the machine.
Do not work with vibration on hard concrete, cured
bitumen layers or extremely frozen ground.
Always keep a sufficient distance when passing
through subways, under bridges, tunnels, electric
power lines etc.
Driving on inclinations and slopes
Do not drive on gradients exceeding the maximum
gradability of the machine.
On slopes drive extremely careful and always directly 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!
Inclination
Fig. 6
The tipping angle was measured in static condition
on level, hard ground with the machine stopped,
no steering and without vibration.
With loose soil, acceleration/deceleration, running
vibration, steering or attached accessoriies the tipping angle may be considerably lower.
Driving across slopes should therefore be strictly
avoided, because of the high risk of tipping over
and the related risk of severe or even fatal accidents.
Safety regulations
BOMAG18 BW 177 D-4
You should therefore always drive straight up or
down a slope.
Behaviour in traffic
Match the speed to the working conditions. Do not
make extreme steering movements when driving
with high speed, danger of tipping over!
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, concrete) ground. Danger of bearing damage!
Parking the machine
Park the machine on horizontal, level, firm ground.
Before leaving the machine:
l Straighten the articulated joint to provide easi-
er access to the machine.
l return the control lever to neutral position
l apply the parking brake
l shut the engine down, pull the ignition key off
l close the cabin
l secure the machine against unintended use.
Do not jump off the machine, but use hand grips
and access steps.
Mark machines, which could be in the way, with a
clearly visible sign.
Parking on slopes and inclinations
Secure the machine against rolling, place metal
chocks in front of and behind the wheels. The
wheel chocks must be provided by the operating
company.
Refuelling
Do not inhale any fuel fumes.
Refuel only with the engine shut down.
Do not refuel in closed rooms.
No open fire, do not smoke.
Monitor the entire refuelling process.
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. Ensure tight fit of the fuel tank cover, if necessary replace immediately.
Fire protection measures
Familiarise yourself with the location and the operation of fire fighting equipment. Observe all fire reporting and fire fighting possibilities.
Maintenance work
Comply with the maintenance work described in
these operating and maintenance instructions, including the information concerning the replacement of parts.
Maintenance work must only be performed by
qualified and authorized persons.
Support the engine hood for all maintenance and

For overhead maintenance and assembly work
use the access steps and working platforms provided or other secure means. Do not use machine
parts as access steps.
Keep unauthorized persons away from the machine.
Do not perform maintenance work while the machine is driving or the engine is running.
Park the machine on horizontal, level, firm ground.
Remove the key from the ignition switch.
Secure the articulated joint with the articulation
lock.
Work on hydraulic lines
Relieve hydraulic pressures before working on hydraulic lines. Hydraulic oil escaping under pressure 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.
Safety regulations
BOMAG 19BW 177 D-4
Do not change the setting of pressure relief valves.
Drain the hydraulic oil at operating temperature –
danger of scalding!
Any hydraulic oil must be caught and disposed of
in an environmentally friendly manner.
Always catch and dispose of hydraulic oils separately.
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 not be mixed up by mistake.
Hydraulic hoses must be visually inspected at regular intervals.
Hydraulic hoses must be immediately replaced if:
l the outer layer is damaged down to the inlay
(e.g. chafing, cuts, cracks),
l embrittlement of the outer layer (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 hydraulic hose,
l the hose shows deformations in bends, e.g.
squeezing, buckling, layer separation, formation 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.
l the permissible storage and usage period is
exceeded.
Only genuine BOMAG replacement hydraulic hoses ensure that the correct hose type (pressure
range) is used at the right location.
Working on the engine
Do not work on the fuel system while the engine is
running - danger to life due to high pressures!
l Wait another minute 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 dispose of environmentally.
Store used filters and other oil contaminated materials 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
turbo 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 machine disconnect the battery and cover it with insulating material.
Do not use fuses with higher ampere ratings and
do not bridge fuses - fire hazard!
Disconnect battery and plugs from the control
units 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.
Safety regulations
BOMAG20 BW 177 D-4
Metal objects (e.g. tools, rings, watch straps) must
not come in contact with the battery poles – danger of short circuit and burning!
When recharging non-serviceable batteries remove all plugs, to avoid the accumulation of explosive 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.
Ensure sufficient ventilation, especially if the battery is to be charged in a closed room.
Working on the fuel system
Do not inhale any fuel fumes.
Avoid open fire, do not smoke, do not spill any fuel.
Catch running out fuel, do not let it seep into the
ground and dispose off environmentally.
Working on wheels and tires
Explosion-like bursting of tires or parts of tires and
rims can cause most severe or even deadly injuries.
Install the tires only if are sufficiently experienced
and with the right tools at hand. If necessary have
the tires assembled in a qualified workshop.
Always ensure the correct tire pressure and do not
exceed the specified maximum pressure.
Check tires and wheels every day for specified
pressure, cuts, bulges, damaged rims, missing
wheel studs or nuts. Do not drive with damaged
tires or wheels.
Ant-sticking emulsions for tires must only consist
of water and anti-sticking agent, in a concentration
in accordance with the specifications of the manufacturer of the anti-sticking agent. Observe applicable environmental regulations.
Working on the air conditioning
Faults on the air conditioning should only be remedied by professional personnel.
According to the regulation for pressure reservoirs
all pressure reservoirs must be repeatedly inspected by a specialist.
In connection with this inspection the drier/collector unit must be visually examined twice every
year. During these inspections special attention
must be paid to corrosion and mechanical damage.
Do not perform welding work in the vicinity of the
air conditioning. Danger of explosion!
Do not clean the condenser in the air conditioning
system with a hot water jet. Danger of explosion!
Do not release refrigerant into the atmosphere, but
dispose of environmentally.
Cleaning work
Do not perform cleaning work while the motor is
running.
Do not use gasoline or other easily inflammable
substances for cleaning.
When cleaning with steam cleaning equipment do
not subject electrical parts and insulation material
to the direct jet of water, or cover it beforehand.
l Do not guide the water jet into the exhaust and
into the air filter.
After maintenance work
After all maintenance work is completed reinstall
all guards and safety installations.
Repair
Mark a defective machine by attaching a warning
tag to the steering wheel.
Repair work must only be performed by qualified
and authorized persons. Use our repair instructions for this work.
Exhaust gases are highly dangerous! Always ensure an adequate supply of fresh air when starting
in closed rooms!
Do not work on the fuel system while the engine is
running - danger to life!
The system is under high pressure! Keep away
from leakages in the high pressure system, because fuel squirting out may cause severe injury.
After shutting down the engine wait for another
minute, until the pressure has dropped to a permissible level. In case of leakages you should contact the Service Department of the engine
manufacturer and refrain from starting the engine.
Test
The safety of compaction equipment must be
checked by a specialist as required in dependence
on the application and the operating conditions,
however at least once every year.

A wrong connection will cause severe damage
in the electric system.
l Bridge the machine only with a 12 Volt auxilia-
ry battery.
l When jump starting with an external battery
connect both plus poles first.
l Then connect the ground cable first to the mi-
nus pole of the current supplying auxiliary battery and then to engine or chassis ground, as
far away from the battery as possible (Fig. 53).
l Start as described under 'Starting the engine'.
l Once the engine is running switch on a power-
ful consumer (working light, etc.).
Caution
!
If no powerful consumer is switched on voltage peaks may occur when separating the connecting cables between the batteries, which
could damage electrical components.
l After starting disconnect the negative poles
(ground cable) first and the positive poles after.
l Switch off the consumer.

5.6 Driving the machine
Danger!
Danger of accident!
Wet and loose soils considerably reduce the
ground adhesion of the machine on inclinations and slopes.
Soil conditions and weather influences impair
the gradability of the machine.
Do not drive up and down inclinations exceeding the maximum gradability of the machine
(see technical data).
Do not drive without wearing your seat belt.
Always give way to loaded transport vehicles!
Before starting to drive make sure that the
drive range is absolutely safe.
Caution
!
Always keep the cabin door closed while driving with the machine. With the door opened
and the machine fully articulated extreme oscillations of the machine may damage the
door.
Note
i
The machine is equipped with a seat contact
switch (safety feature).
If the driver gets up from his seat while driving, the
signal horn is activated and the machine is slowed
down to standstill after four seconds. When the

6.1 General notes on maintenance
When performing maintenance work always comply with the appropriate safety regulations.
Thorough maintenance of the machine guarantees far longer safe functioning of the machine and
prolongs the lifetime of important components.
The effort needed for this work is only little compared with the problems that may arise when not
observing this rule.
The terms right/left correspond with travel direction forward.
l Support the engine hood for all maintenance
and repair work.
l Do not touch hot engine parts.
l Always clean machine and engine thoroughly
before starting maintenance work.
l For maintenance work stand the machine on
level ground.
l Perform maintenance work only with the en-
gine shut down.
l Relieve hydraulic pressures before working on
hydraulic lines.
l Before working on electric parts of the ma-
chine disconnect the battery and cover it with
insulation material.
l When working in the area of the articulated
joint attach the articulation lock (transport
lock).
Environment
During maintenance work catch all oils and fuels and do not let them seep into the ground or
into the sewage system. Dispose of oils and fuels environmentally.
Keep used filters in a separate waste container
and dispose of environmentally.
Catch biodegradable oils separately.
Notes on the fuel system
The lifetime of the diesel engine depends to a
great extent on the cleanliness of the fuel.
l Keep fuel free of contaminants and water,
since this will damage the injection elements
of the engine.
l Drums with inside zinc lining are not suitable to
store fuel.
l When choosing the storage place for fuel
make sure that spilled fuel will not harm the environment.
l Do not let the hose stir up the slurry at the bot-
tom of the drum.
l The fuel drum must rest for a longer period of
time before drawing off fuel.
l The rest in the drum is not suitable for the en-
gine and should only be used for cleaning purposes.
Notes on the performance of the engine
On diesel engines both combustion air and fuel injection quantities are thoroughly adapted to each
other and determine power, temperature level and
exhaust gas quality of the engine.
If your engine has to work permanently in "thin air"
(at higher altitudes) and under full load, you should
consult the customer service of BOMAG or the
customer service of the engine manufacturer.
Notes on the cooling system
Prepare and check coolant with highest care,
since otherwise the engine may be damaged by
corrosion, cavitation and freezing.
Coolant is prepared by adding an ethylene-glycol
based anti-freeze agent with corrosion inhibiting
properties to the cooling water.
Mixing with cooling system protection agent is
necessary in all climatic zones. It prevents corrosion, lowers the freezing point and raises the boiling point of the coolant.
Notes on the hydraulic system
During maintenance work on the hydraulic system
cleanliness is of major importance. Make sure that
no dirt or other contaminating substances can enter into the system. Small particles can produce
Maintenance
BOMAG 75BW 177 D-4
flutes in valves, cause pumps to seize, clog nozzles and pilot bores, thereby making expensive repairs inevitable.
l If, during the daily inspection of the oil level the
hydraulic oil level is found to have dropped,
check all lines, hoses and components for
leaks.
l Seal external leaks immediately. If necessary
inform the responsible customer service.
l Do not store drums with hydraulic oil outdoors,
or at least under a cover. Water can be drawn
in through the bunghole when the weather
changes.
l We recommend to use our filling and filtering
unit with fine filter to fill the system. This ensures finest filtration of the hydraulic oil, prolongs the lifetime of the hydraulic oil filter and
protects the hydraulic system.
l Clean fittings, filler covers and the area around
such parts before disassembly to avoid entering of dirt.
l Do not leave the tank opening unnecessarily
open, but cover it so that nothing can fall in.
6.2 Fuels and lubricants
Engine oil
Quality
For use in DEUTZ engines the lubrication oils are
classified in DEUTZ Lubrication Oil Quality Classes (DQC).
The list of approved lubrication oils is also available in the Internet under the following address:
Consult your local service station if in doubt.
l Use winter grade engine oil for winter opera-
tion!
Oil viscosity
Since lubrication oil changes its viscosity with the
temperature, the ambient temperature at the operating location of the engine is of utmost importance when choosing the viscosity class (SAEclass) .

Too high viscosity can cause starting difficulties,
too low ´viscosity can jeopardize the lubrication effect and result in a high lubrication oil consumption.
Fig. 121
Optimal operating conditions can be achieved by
using the oil viscosity chart (Fig. 121) as a reference.
At ambient temperatures below -40 °C (-58 °F) the
lubrication oil must be pre-heated (e.g. by parking
the machine indoors).
The viscosity is classified acc. to SAE. Multi-purpose oils should generally be used.
Oil change intervals
The longest permissible time a lubrication oil
should remain in an engine is 1 year. If the following oil change intervals are not reached over a period of 1 year, the oil change should be performed
at least once per year, irrespective of the operating
hours reached.
DQC II, DQC III, DQC IV: 500 operating hours
Caution
!
When using fuels with a sulphur content of
more than 0.5% to 1% or under permanent ambient temperatures below -10 °C (14 °F) and
when using biodegradable diesel fuel the oil
change intervals must be halved.
Fuels
You should only use commercially available brand
diesel fuel with a sulphur content of less than 0.5%
and ensure strict cleanliness when filling in. A
higher sulphur content has a negative effect on the
oil change intervals.
The fuel level should always be topped up in due
time so that the fuel tank is never run dry, as otherwise filter and injection lines need to be bled.
Quality
The following fuel specifications are permitted:
l EN 590
l DIN 51628
l ASTM D975 Grade-No. 1-D and 2-D.
l JIS K 2204 Grade Fuel 1 and Grade Fuel 2
with lubrication properties acc. to EN 590
Winter fuel
For winter operation use only winter diesel fuel, to
avoid clogging because of paraffin separation.
Diesel fuels suitable for temperatures down to -44
°C (-47 °F) are available for Arctic climates. At
very low temperatures disturbing paraffin separation can also be expected when using winter diesel
fuel.
The admixture of petroleum and the addition of
"flow enhancing additives" (fuel additives) is not
permitted.
Mineral oil based hydraulic oil
The hydraulic system is operated with hydraulic oil
HV 46 (ISO) with a kinematic viscosity of 46 mm
2
/
s at 40 °C and 8 mm
2
/s at 100 °C. For topping up
or for oil changes use only high-quality hydraulic
oil, type HVLP according to DIN 51524, part 3, or
hydraulic oils type HV according to ISO 6743/3.
The viscosity index (VI) should be at least 150 (observe information of manufacturer).
Maintenance
BOMAG 77BW 177 D-4
Bio-degradable hydraulic oil
The hydraulic system can also be operated with a
synthetic ester based biodegradable hydraulic oil.
The biologically quickly degradable hydraulic oil
Panolin HLP Synth.46 meets all demands of a
mineral oil based hydraulic oil according to
DIN 51524.
In hydraulic systems filled with Panolin HLP
Synth.46 always use the same oil to top up.
When changing from mineral oil based hydraulic
oil to an ester based biologically degradable oil,
you should consult the lubrication oil service of the
oil manufacturer for details.
Caution
!
Check the filter more frequently after this
change.
Perform regular oil analyses for content of water and mineral oil.
Replace the hydraulic oil filter element every
500 operating hours.
Gear oil
For the gearboxes use only ,ulti-purpose gear oils
ISO VG 220 of API-GL5-class with a minimum viscosity of 20 mm
2
/s at 100 °C.
This is a hypoid lubricant of highest quality class
for extremely loaded transmissions.
The additives in this oil ensure low wear lubrication
under all operating conditions.
Exciter shaft oil
For the exciter unit use a fully synthetic gear oil
SAE 75W-90, API GL5.
Lubrication grease
For lubrication purposes use an EP-high pressure
grease, lithium saponified (penetration 2), acc. to
DIN 51502 KP 2G.

Danger!
Danger of cauterisation ! Danger of explosion!
When working on the battery do not use open
fire, do not smoke!
The battery contains acid. Do not let acid come
in contact with skin or clothes!
Wear protective clothing!
Do not lay any tools on the battery!
For recharging remove the plugs from the battery to avoid the accumulation of highly explosive gases.
Environment
Dispose of the old battery environmentally.
Note
i
Maintenance free batteries also need care. Maintenance free only means that the fluid level does
not need to be checked. Each battery suffers under self-discharge, which may, in not checked occasionally, even cause damage to the battery as a
result of exhaustive discharge.
The following therefore applies for the service
life:
l Switch off all consumers (e.g. ignition, light, in-
side light, radio).
l Check open-circuit voltage of the battery at
regular intervals. At least once per month.
Reference values: 12.6 V = fully charged; 12.3 V =
50% discharged.
l Recharge the battery immediately after an
open-circuit voltage of 12.25 V or less is
reached. Do not perform quick charging.
The open-circuit voltage of the battery occurs approx. 10 hours after the last charging process or
one hour after the last discharge.
l After each charging process allow the battery
to rest for one hour before taking it into service.
l For resting periods of more than one month
you should always disconnect the battery. Do
not forget to perform regular open-circuit voltage measurements.
Caution
!
Exhausted batteries (batteries with formation
of sulphate on the plates) are not covered under warranty!
l Open the engine hood and remove the cover-
ing
Fig. 150
l Remove the battery (Fig. 150) and clean the
battery compartment.
l Clean the outside of the battery.
l Clean battery poles and pole clamps and
grease them with pole grease (Vaseline).
l Check the fastening of the battery.
l On serviceable batteries check the acid level,
if necessary top up to the filling mark with distilled water.
