(2) Lubricate in accordance with the
lubrication instructions.
(3) If storing for a long period of time,
proceed as follows.
‒ Coat the cylinder rods with a suffi
cient
quantity of antirust oil.
‒ Start the engine and check operation once
every month, so as to ensure that the oil
fi lm on lubricated parts remains intact.
‒ Before checking the operation, remove the
coating of antirust oil from the oil cylinder
rod.

• Do not use high-pressure washing.
• If working in winter, be careful to avoid
ice formation.

(5) Periodically operate the boom, so as to
maintain the oil fi lm on its lubricated parts.
(6) If the boom is left extended or raised
while the hydraulic oil temperature is high,
the boom may retract or lower somewhat.
This is caused by the contraction of the
hydraulic oil confi ned in the hydraulic
cylinders due to a change in the hydraulic
oil temperature.
NOTICE
If the hydraulic oil temperature drops
10℃ with the boom fully extended and
raised, the boom will retract approx. 30
mm.
This value, however, varies depending
on the boom length and the boom
angle.
