Motorised trucks can become hazardous if maintenance and servicing work are neglected. For this reason maintenance and inspections must be performed
at sufficiently short intervals. There must be suitably
trained personnel and proper guidelines at your place
of work.
• Do not allow oils to penetrate the ground or the
drain system. Used oil must be recycled correctly.
Oil filters and dehumidifying inserts must be
treated as special waste. Observe the local authority regulations.
• Immediately neutralize and thoroughly rinse any
spilled battery fluid.
• Keep the truck clean. This will facilitate tracing
loose or faulty components.
• Maintain the legibility of the data capacity plate and
data plate, warning and instruction decals.
• Truck modifications and additions may only be per-
formed with Crown’s prior written approval.
• The reliability, safety and suitability of Crown
trucks can only be ensured by using original Crown
parts.
Maintenance and Repair
•
Always carry out work in accordance with the test
and maintenance schedule enclosed in these
maintenance instructions and any applicable service bulletins.

CONTROL OF HAZARDOUS ENERGY
Control of Hazardous Energy
In the interest of safety Crown has developed guidelines for proper energy control when performing service and maintenance on the SP 3400.
Before performing any service or maintenance on
the SP 3400, review the appropriate sections in this
service manual for additional procedures to be followed.
In addition, Crown recommends that all mechanics
wear appropriate protective items, such as safety
glasses, work gloves, and steel toed shoes, whenever
performing service or maintenance work on Crown
equipment.
Battery
Warning
[one pound to one US gallon of water] will neutralise acid spilled on clothing, the floor or any other
surface. Apply solution until bubbling stops and
rinse with clean water.
• Keep vent plugs firmly in place at all times except
when adding water or taking hydrometer readings.
• Do not bring any type of flame, spark, etc., near the
battery. Gas formed while the battery is charging is
highly explosive. This gas remains in the cells long
after charging has stopped.
• Do not lay metallic or conductive objects on the
battery. Arcing will result.
• Do not allow dirt, cleaning solution or other foreign
materials to enter cells. Impurities in electrolyte
have a neutralising effect, reducing the available
charge.
Only qualified and experienced personnel should perform maintenance and
repair on batteries.
Follow the battery’s and charger manufacturer’s instructions concerning
practices and procedures for charging,
maintenance and repair.
Safety Rules
• Wear protective clothing such as a rubber apron,
gloves, boots and a full-face shield when performing any maintenance on batteries.
• Do not allow electrolyte to come in contact with
eyes, skin, clothing or floor. If electrolyte comes in
contact with eyes, flush immediately and thoroughly with clean water. Obtain medical attention
immediately.
Make certain the charger being used matches the voltage and amperage of the truck battery. This voltage is
listed on the truck data plate.
Before disconnecting or connecting batteries to a
charger, make sure the charger is “OFF”. If an attempt
is made to do this while the charger is “ON”, serious
injury to you and damage to the battery and charger
could result.
Make sure that the battery used meets the weight, size
and voltage requirements of the truck (refer to data
plate). Never operate the truck with an undersized
battery.
• Should electrolyte be spilled on skin, rinse
promptly with clean water and wash with soap. A

Warning
Avoid high pressure fluids!
Escaping fluid under pressure can penetrate the skin causing serious injury.
Relieve pressure before disconnecting
hydraulic lines. Tighten all connections
before applying pressure. Keep hands
and body away from pin holes which
eject fluids under high pressure. Use a
piece of cardboard or paper to search
for leaks. Do not use your hand.
Any fluid injected into the skin under
high pressure should be considered as
a serious medical emergency despite
an initial normal appearance of the
skin. There is a delayed onset of pain,
and serious tissue damage may occur.
Medical attention should be sought immediately by a specialist who has had
experience with this type of injury.
