2.5 MAINTENANCE SAFETY
Unsafe Maintenance Hazards
• Before performing any adjust-
ment or service operations, power
off all control units and ensure
that all moving parts are safely se-
cured and cannot move
unintentionally.
• Before performing any adjust-
ment or service operations, en-
sure that the boom is stowed.
Never work under a raised plat-
form/boom. If it becomes neces-
sary to work under the raised
platform/boom, the platform and
boom must be supported with ap-
propriate safety supports.
• When lifting or moving heavy
parts of the machine, use equip-
ment with sufficient capacity, and
never place heavy objects in an
unstable position after moving.
• When machine parts are lifted by
other equipment, ensure that
there are no persons are under
and/or around the equipment.
• When striking brass rods with a
mallet, make sure to wear eye
protection.
• If you need to replace parts, use
only original parts specified by
Sinoboom.
• Do not wash the machine with
water. The machine contains elec-
tronic components such as sole-
noid valves and sensors, which
may fail or operate erratically after
water ingress. If it is necessary to
wash with water, turn off the main
power switch before proceeding.
Only turn the power back on after
ensuring the machine is com-
pletely dry.
• Make sure the machine is turned
off before using flushing equip-
ment (such as high-pressure
water gun) to clean the machine.
Do not direct water or steam
ejected from the flushing at elec-
trical components, as this may
cause short-circuits or electrical
shocks.
• After maintenance is completed,
thoroughly clean up any spilled
hydraulic oil, and avoid allowing it
