The operting onitions of the prouts shown in this tlog vry epening upon eh pplition. Therefore, the eision of the prouts' suitility to the system onsiere must e me y the esigner of the hyruli system n/or the person in hrge of etermining the speifition fter mking nlysis n onuting tests, if neessry. The stuy of the speifition shll e one se on the ltest tlog n tehnil ouments, n the system must e ompose tking into ount situtions regring the possiility of mhine filure. rior to use of the prouts, esriptions given in the SAFETY RES must e oserve for the proper use. The tehnil informtion in this tlog represents typil hrteristis n performne of the prouts, n is not gurntee one. In se the prouts re use in the following onitions or environments, plese onsult us prior to the use. Unspeifie onitions or environments Use for tomi power, vition, meil tretment, n/or foo Use likely to ffet humn eings or ssets signifintly or requiring prtiulr sfety The informtion esrie in this tlog is sujet to hnge without notie.

3 SAFETY RES Before you use the prout, you MUST re the opertion or opertors mnul n MUST fully unerstn how to use the prout. To use the prout sfely, you MUST refully re ll Wrnings n Cutions in this mnul. You MUST lso oserve the relte regultions n rules regring sfety. Cutions relte to opertion Wrnings n Cutions for opertion Use the sfety equipment to voi the injury when you operte the prout. DANGER Never use the prout not equippe with nti-explosion protetion in the irumstnes of possile explosion or omustion. y enough ttention on hnling metho to voi pinhing hns or k prolems tht my e use y hevy weight of the prout or hnling posture. Do not step on the prout, hit it, rop it or give strong outsie fore to it, s one of these tions my use the filure of work, mge or oil lekge. Wipe the oil on the prout or floor off ompletely, s the oil retes slippery onitions tht my result in ropping the prout or injuring. WARNING WARNING Shiel the rotting prt suh s motor shft n pump shft to voi injuries use y eing ught of fingers or loths. Stop the opertion immeitely if you fin something wrong suh s unusul noise, oil lekge or smoke, n fix it properly. If you ontinue operting, you my enounter mge, fire or injury. Mke it sure tht pluming n wiring re orret n ll the onnetion is tightene orretly efore you strt operting, espeilly if it is the first run. Wrnings n Cutions relte to instlltion n removl of the prout WARNING Instlltion, removl, pluming, n wiring must e one y the ertifie person. *CERTIFIED ERSON: person who hs enough knowlege like person who is trine y Kwski s hyruli shool. Mke it sure tht the power of the hyruli power unit is turne off n tht the eletri motor or engine hs ompletely stoppe efore strting instlltion or removl. You must lso hek the system pressure hs roppe to zero. Use the prout uner the speifition mentione in the tlog, rwings n speifition sheet. Keep your oy off the prout uring the opertions s it my eome hot n urn your oy. Use the proper hyruli oil, n mintin the ontmintion in the reommene level, otherwise it my not work or e mge. Cutions relte to mintenne WARNING Turn off the power efore strting wiring or other works relte to the eletri power, otherwise you my e stuk y n eletri shok. Clen the thres n mounting surfe ompletely, otherwise you my experiene mges or oil lekge use y insuffiient tightening torque or roken sel. Use the speifie olts n keep the speifie tightening torque when you instll the prout. Usge of unuthorize olts, lk of torque or exess of torque my rete prolems suh s filure of work, mge n oil lekge. Never moify the prout without pprovl of Kwski. Do not isssemle n ssemle without pprovl y Kwski. It my use troules n filure, or it my not work s speifie. If it is neessry y ll mens to isssemle n ssemle, it must e one y n uthorize person. Keep the prout from ust n rust y pying ttention to the surrouning temperture n humiity when you trnsport or store the prout. Repling the sels my e require if you use the prout fter long time storge. 2
