Dis as sem bly is just as easy. 3.1 Handle/seat unit The hol ding de vi ce has to be par al lel to the hou sing. Only aut ho ri zed AAT dea ler or an AAT re pre sen ta ti ve are al lo wed to ad just the hol ding de vi ce. First con nect the hand le/seat unit with the clim bing unit by in ser ting the co - lumn of the hand le/seat unit (seat poin ting for ward) into the hol ding device on the clim bing unit. A 9-pin Sub-D so cket con nec tor lo ca ted in the clim bing unit s hol ding de - vi ce ma kes the elec tri cal con nec ti on. 11

12 Se cu re the con nec ti on with the tighte ning knob. Plea se al ways make sure that the hand le/seat unit is sa fe ly con nec - ted to the clim bing unit. Plea se only con nect the hand le/seat unit with the clim bing unit if both parts are cle an and dry. Should the re be dirt or moi stu re the two parts should ne ver be con nec ted. Cle an and dry the Sub-D so cket connector with a re gu lar clea ning cloth. You may not con nect ot her de vi ces to the Sub-D so cket connector. This could de stroy the s-max sel la or the ot her elec tri cal de vi ces. 3.2 Attach the battery pack Push the bat te ry pack si de ways into the clim bing unit; once con nec ted it is au to ma ti cal ly locked. 3.3 Detach the battery pack Push down the lo cking lever on the clim bing unit and take out the bat tery pack. 12

When a per sons ta kes a seat on the s-max sel la, plea se fol low the se in struc - tions: 1. First, lock the stee ring rollers at their lo cking de vi ce. 2. To avoid the s-max sel la mo ving when a per son ta kes a seat, you must fold out the clim ber in such a way that it rests on the ground. Turn on the de vi ce and press the UP/DOWN switch, di rec ti on UP un til the clim ber tou ches the floor. 3. Sit ting down can be fa ci li ta ted by fol ding out the arm rests. If ne - ces sa ry, you can re mo ve the arm rests al to get her. Af ter the per son to be trans por ted has ta ken a seat you put the arm rests back into their ori gi nal position. 4.

In or der to slow down you need to tilt the s-max sel la a bit more, so that the sa fe ty bra kes are activated. 26

27 6.10 Climbing upstairs You may only be per mit ted to trans port a per son with the s-max sella, if you have been pro per ly trai ned in the device s ope ra ti on. Plea se al ways prac ti ce clim bing stairs wit hout a per son and by ac ti - va ting the sing le step mode plus the lo west clim bing speed. Plea se al ways check the sa fe ty bra kes be fo re each use (see chap ter 6.4 and 8.5). The clim bing pro cess can be ac com plis hed quic kly and wit hout pro blems if you ad he re clo se ly to the fol lo wing in struc tions. A tip be fo re you start: Al ways pull the s-max sel la a bit bac kwards du ring the en ti re clim - bing pro cess, i.e. al ways keep the de vi ce un der ten si on so that the wheels can touch down pro per ly on the next step. 1. Ad just the hand le to the ap pro pria te height (see chap ter and 6.7). 2. Turn the s-max sel la on by pressing the ON/OFF switch. 3. De ac ti va te the sing le step mode if necessary (see chap ter 6.2.3). 4. Pull in the clim ber to its top most po si ti on by pres sing the UP/DOWN switch (see chap ter 6.3) 5. Tilt the s-max sel la slight ly to ward you (see chap ter 6.8). 6. Dri ve bac kwards to the stairs and move up 2 to 3 steps. Now the s-max sel la is in its in iti al po si ti on for clim bing upstairs. Make sure that both main wheels touch the lo west step. 27

28 The clim bing pro cess ta kes pla ce in two intervals. 7. Press the UP/DOWN switch, di rec ti on UP to be gin the clim bing pro - cess by mo ving the clim ber downward. Al ways keep the de vi ce un der ten si on du ring the en ti re clim bing pro cess, i.e. al ways pull it slight ly bac kward toward you. Af ter the clim ber re aches the floor, it as su mes the load of the main wheels whi le the main wheels and the fra me are lif ted at the same time. The first in ter val is fi nis hed when the main wheels touch down on the next hig her step and re su me the load of the clim ber. 28

29 The se cond in ter val be gins by pul ling in the clim ber. It is fi nis hed when the clim ber rea ches its top most po si ti on. Be cau se the s-max sel la is al ways pul led slight ly bac kward, it rolls au to ma ti - cal ly to the next step and rea ches the in iti al po si ti on again - both main wheels touch the next step. Sin ce the sing le step mode is ac ti vat ed each time be fo re you turn on the s-max sel la, the clim bing pro cess ends here. To re su me clim bing, you need to press the UP/DOWN switch once again, di rec ti on "UP". At this point the clim bing pro cess re pe ats it self as des cri bed in point 7. 29

30 6.11 Climbing downstairs You may only be per mit ted to trans port a per son with the s-max sel - la, if you have been pro per ly trai ned in the device s ope ra ti on. Plea se al ways prac ti ce clim bing stairs wit hout a per son and by ac ti - va ting the sing le step mode plus the lo west clim bing speed. Plea se al ways check the sa fe ty bra kes be fo re each use (see chap ter 6.4 and 8.5). The clim bing pro cess can be ac com plis hed quic kly and wit hout pro blems if you ad he re clo se ly to the fol lo wing in struc tions. 1. Ad just the hand le to the ap pro pria te height (see chap ter and 6.7). 2. Turn the s-max sel la on by pressing the ON/OFF switch. 3. De ac ti va te the sing le step mode if ne ces sa ry (see chap ter 6.2.3). 4. Pull in the clim ber to its top most po si ti on by pres sing the UP/DOWN switch (see chap ter 6.3) 5. Tilt the s-max sel la slight ly to ward you (see chap ter 6.8). 6. Dri ve the s-max sel la for ward to the edge of the stairs. The sen sit vie rolls of the sa fe ty brakes keep the s-max sel la from rol ling over the edge. 7. Press the UP/DOWN switch, di rec ti on DOWN and the des cen ding pro cess be gins. The dri ve re tracts the clim ber downward and tou ches down on the next lo wer step. 30

31 When the clim ber re aches the next lo wer step it re su me the load of the main wheels, whi le tho se plus the clim bing fra me are lif ted off the hig her step and then mo ves downward, away from the ope ra tor. Now the main wheels and the clim bing fra me are mo ved forward - away from the ope ra tor. Af ter wards the main wheels and the fra me are lo we red by re trac ting the clim ber. This re sults in a small shift in load dis tri bu ti on, which you will feel at the hand le by a slight pull for ward. The main wheels rest now on the next step (see pic tu re) and re su me the load from the clim ber, which is re trac ted furt her. Sin ce the sing le step mode is ac ti vat ed every time you turn on the de vi ce, the clim ber is pul led in en ti re ly and then the des cen ding pro cess ends at this point. 8. Again push the s-max sel la all the way to the edge of the step, i.e. un til the sen si ti ve rolls of the sa fe ty bra kes stop the s-max sel - la. To con ti nue des cen ding you need to press the UP/DOWN switch again, di - rec ti on DOWN. At this point the clim bing pro cess re pe ats it self as des cri bed in point 7. 31

32 6.12 Laying the s-max sella down on the stairs In an emer gen cy the s-max sel la may tilt bac kwards and lay down on the stairs. The sa fe ty bra kes pre vent the s-max sella from rol ling down (see pic - tu re) Fold up the handle/seat unit To fold up the s-max sel la, plea se fol low the se in struc tions: 1.
