Battery electrolyte is dilute sulfuric acid.
Exposure of skin or eyes to this liquid will cause
burning or loss of eyesight. If the exposure
occurs, take the following emergency measures
and seek the advice of a medical specialist.
• When skin exposed: Wash with water and soap
sufficiently.
• When eyes exposed: Immediately wash away
with city water continuously for more than 10
minutes.
• When a large amount of the liquid flows out:
Neutralize with sodium bicarbonate or wash
away with city water.
• When swallowed: Drink a large amount of milk
or water.
• When clothes exposed: Immediately undress
and wash.
1.5 HYDRAULIC PARTS
1) O-ring
• Ensure O-rings have elasticity and are not
damaged before use.
• Use the appropriate O-rings. O-rings are made
of various kinds of materials having different
hardness to apply to a variety of parts, such as
the part for moving or fixed portion, subjected
to high pressure, and exposed to corrosive fluid,
even if the size is same.
• Fit the O-rings without distortion and bend.
• Always handle floating seals as a pair.
2) Flexible hose (F hose)
• Use the appropriate parts. Different parts are
used depending on the working pressure even
the size of fitting and the total length of the hose
is same.
• Tighten the fitting at the specified torque. Ensure
no kink, tension, interference nor oil leakage is
recognized.
1.6 WELDING REPAIR
(1) Refer repair welding to qualified personnel
according to the appropriate procedure.
(2) Disconnect the ground (earth) cable of the battery
before starting the repair. Failure to do so will
cause damage to the electrical equipment.
(3) Move away the articles in advance that may cause
fire if exposed to sparks.
(4) Before starting the repair of the attachment, do
not fail to cover the plated surface of the piston
rod with flameproof sheet to prevent it from being
exposed to sparks.
1.7 ENVIRONMENTAL MEASURE
(1) Run the engine at the place that is sufficiently
ventilated.
(2) Industrial waste disposal
Dispose of the following parts according to the
relevant regulations:
Waste oil and waste container
Battery
(3) Precautions for handling hydraulic oil
Exposure of eyes to hydraulic oil will cause
inflammation. Wear protective glasses before
handling to avoid an accident. If an eye is exposed
to the oil, take the following emergency measures:
• When an eye exposed: Immediately wash away
with city water sufficiently till stimulative feeling
vanishes.
• When swallowed: Do not let vomit, and receive
medical treatment immediately.
• When skin exposed: Wash with water and soap
sufficiently.
(4) Others
Use genuine replacement parts and
lubricants
