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.

1.1.6

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.

1.1.7

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 replacement parts and lubricants authorized as the manufacturer's genuine parts.
