U20-3, U25-3 WSM

(4) Precautions in tightening hoses and pipes.

• Flexible hoses have a slight natural bend of
their own. Utilize the natural bend. Be also
careful not to twist them.
• Be careful not to confuse the routes of the
hoses.
• Do not hold the hoses in tight contact with
their adjacent parts and surfaces.
• Tightening steps
1. First tighten the nut to its specified
torque.
2. Then loosen the nut by about 45° to fit
the seat of the joint to the connection.
(5) The quantities of oil, fuel, water and others,
except for the oil to be filled in the track rollers
and idlers, are listed just as reference. Fill up
the fluid up to the specified center level of a
level gauge if it is provided.
(6) Security support the machine with a jack and a
supporting jig when it is jacked up for
servicing.
(7) Be sure to use a crane in disassembling and
reassembling heavy parts and components
(frame, front attachment, crawler, etc.).
