3 Owner's Mnul for Thern Model 548 Floor Crne pge 3 Suggestions for Sfe Opertion DO the following: Red nd comply with the guidelines set forth in this Owner s Mnul. Keep this mnul, nd ll lels ttched to the crne, redle nd with the equipment t ll times. Contct Thern, Inc. for replcements. Check luriction efore use. Use sling or other pproved lifting device. Keep hnds wy from moving prts of the equipment. Keep ll unnecessry personnel wy from crne while in opertion. Keep csters locked when not intending to move crne. DO NOT do the following: Do not lift people, or things over people. Do not wlk or work under lod or in the line of force of ny lod. Do not exceed the lod rting of the crne or ny other component in the system. To do so could result in filure of the equipment. Do not use more thn one crne to move lod tht exceeds the lod rting of single crne. A shift in lod weight could overlod the equipment. Do not use dmged or mlfunctioning equipment. To do so could result in filure of the equipment. Do not modify the equipment in ny wy. To do so could cuse equipment filure. Do not divert your ttention from the opertion. Sty lert to the possiility of ccidents, nd try to prevent them from hppening. Do not jerk or swing the lod. Avoid shock lods y strting nd stopping the lod smoothly. Shock lods overlod the equipment nd my cuse dmge. Do not use the crne for ny reson other thn for the originl intended function. Do not use the crne to drg or pull lods. This will crete side pulls which could dmge the equipment or cuse the lod to tip. Do not leve suspended lod unttended. Plce the lod on the ground if it must e left unttended. Do not operte or pply lods without ll pins securely in plce. Do not djust the oom extension while the crne is loded.

4 pge 4 Owner's Mnul for Thern Model 548 Floor Crne 1.1 Assemling the Crne Inspect the crne during ssemly ccording to the Instructions for Periodic Inspection. This will give you record of the condition of the crne with which to compre future inspections. Sve ll oxes nd crtes tht the crne ws shipped in, use them gin if you need to repckge the crne. Contct the fctory immeditely if ny prts re missing or dmged. Do not overtighten fsteners, this my strip threds or cuse dmge to other prts. When the oom is relesed from its folded position, it moves rpidly nd with force. Keep the re in front of the oom (etween the crne legs) cler of ny ostruction when relesing the oom open crton nd thoroughly check contents ginst prts list Study prts drwings to understnd how the crne is ssemled. See pges luricte pins nd other components prior to ssemly. See Section 3.2 Luricting the Crne ssemle the crne in the following order: ssemle the swivel csters (item 2) to the crne with 5/16" x 3/4" cp screws (item 3), 5/16" lock wshers (item 5) nd 5/16" hex nuts (item 4). ssemle the wheels (item 6) t the ends of the legs (item 20 nd 21) using the xle olts (item 19).

5 Owner's Mnul for Thern Model 548 Floor Crne pge Generl Theory of Opertion It is your responsiility to detect nd ccount for different fctors ffecting the condition nd performnce of the equipment. Avoid shock lods creted y quickly opening nd closing the relese vlve s lod is eing lowered. Shock lods my overlod the hydrulic circuit nd cuse dmge to the jck THE INTENDED USE of this mchinery is to lift nd lower lods of its rted cpcity or less. It is not for lifting people or things over people The force required to move the lod must not exceed the lod rting of the crne. Consider the totl force required to move the lod, not the weight of the lod This equipment cn develop forces tht will exceed the lod rting. It is the responsiility of the equipment user to limit the size of the lod. Inspect the equipment regulrly for dmge ccording to the instructions contined in this mnul Performnce rtings of the equipment re ffected y the position of the oom. Lod rting represents the mximum lod tht cn e plced on new equipment. Lod rtings re ssigned vlues for specific oom positions. The lod rting decreses s you increse oom length. Lift height nd rech vry with the position of the oom Duty rtings refer to the type of use the equipment is suject to. Consider the following when determining duty rting. c d e Environment: hrsh environments include hot, cold, dirty, wet, corrosive, or explosive surroundings. Protect the equipment from hrsh environments when possile. mintennce: poor mintennce, mening poor clening, luriction, or inspection, leds to poor opertion nd possile dmge of the equipment. Minimize poor mintennce y crefully following the instructions contined in this mnul. loding: severe loding includes shock loding nd moving lods tht exceed the lod rting of the equipment. Avoid shock lods, nd do not exceed the lod rting of the equipment. Frequency of Opertion: frequent or lengthy opertions increse wer nd shorten the life spn of erings, sheves, nd other components. Increse mintennce of the equipment if used in frequent opertions. when not in use, lwys leve the hydrulic jck rm ll the wy down AIRBORNE NOISE EMISSIONS vry depending on lod nd the type of winch eing used. Stndrd configurtions do not typiclly exceed sound pressure level of 80dB(A) t worksttions VIBRATION LEVELS vry depending on lod nd type of winch eing used. Stndrd configurtions do not typiclly exceed virtion levels of 2.5 m/s 2. Contct the fctory for more informtion.

6 pge 6 Owner's Mnul for Thern Model 548 Floor Crne 2.2 Prepring for Opertion When determining whether the lod will exceed the lod rting, consider the totl force required to move the lod. Do not use the crne in n re defined s hzrdous y the Ntionl Electric Code, unless use in such n re hs een thoroughly pproved. Do not use the crne ner corrosive chemicls, flmmle mterils, explosives, or other elements tht my dmge the crne or injure the opertor. Adequtely protect the crne nd the opertor from such elements. Use the crne on rigid nd level surfce tht will support the crne nd its lod under ll lod conditions, including shock loding Consider the opertion. Do not egin until you re sure you cn perform the entire opertion without hzrd Inspect ll components of the system. Inspect the CRANE nd other equipment ccording to the Instructions for Frequent Inspection.
