作動油の補給

To refill the oil

エア抜きが完了したら、作動油を適量まで補給してください。(6.保守点検をご参照ください。)

After air releasing is over, refill the oil upto the required level. See 6. Maintenance.

Maintenance

日常の保守点検を怠りますと故障の原因となります。

(1)

作動油の点検

Maintenance of hydraulic working oil

油量は規定量入っていますか?

Is the oil filled upto the required level?

規定量より少ないと、シリンダのピストンが途中から伸びなくなったり、加圧できなくなったりします。

If the oil volume is not enough, the ram piston will not be extended fully, and the pressure will not be rised.

a)

シリンダのピストンの戻し

To retract the ram piston fully

ピストンを出したまま給油しますと、ピストンが戻ったときにタンク内の油があふれ
出ることがあります。また、タンクが破損し、人身事故を起こすおそれがあります。

Retract the ram piston fully. if you fill the oil with the ram piston

extended, when the ram piston retracts, the oil might flow out from

the tank. Moreover, the tank might be damaged, and the personal

injury might be caused.

b)

空気弁の取り外し

To take the air valve out

空気弁を左に回して取り外してください。
レベルゲージが付いています。

*空気弁のねじ部は2か所あります。最初の

ねじ部がはずれましたら、空気弁を引き上げ、
もう一度左に回してください。

Take out the air valve with oil level gauge.
The air valve has two (2) parts of threads.

After the 1st thread part is loosened, pull
out the air valve, and turn it counter-clockwise.

c)

油量の確認

To check the oil level

オイルレベルゲージに付いている油を布等でふき取ります。
給油口にオイルレベルゲージを差し込み、栓がぶつかるまで
中に入れます。もう1度抜き取り、油が油量範囲の間にある
か調べてください。

Clean the oil level gauge by use of waste cloth. Insert the oil level gauge into the oil feeding port until it
touches the screw part. Take it off again to check if the oil level is between the oil level range lines.

d)

油の補給

To refill oil

油量が不足の場合には、給油口より補給してください。油量が適量ならば、オイルレベルゲージを
差し込み、栓を元の状態にねじ込んでください。

If the oil volume is not enough, refill the oil from the oil feeding port. If enough, insert the oil level gauge and

turn it clockwise to close tightly.

作動油は年1回以上交換してください。

Change oil more than once a year

作動油は、一般作動油のISO

VG32 (理研パワーオイル、又は同等品)を

お使いください。リン酸エステル、水-グリコール、w/oエマルジョン系作動油
は使用できません。パッキンの劣化及び機器の腐食などにより、本機が故障しま
す。ご使用の場合には、当社にご連絡ください
