4 Safety instructions

+

For the safe operation of the

C

-max it is highly important that you pay close attention to all instructions regarding operation and safety stressed in this user’s manual.

Instruction: The

C

-max may only be operated by trained personnel. In addition, the operator should be capable of lifting 1/3 of his or her own weight. Minors are not allowed to use the

C

-max; exempt from the above are adolescents over 16 years of age who have been trained under supervision to operate the

C

-max.

While using the

C

-max you should always wear good shoes that do not slip.

Safety brakes: Please check the safety brakes each time befo-

re using the

C

-max (see also chapter 6.4 and 8.7). The safety brakes, particularly the knurled surface of the brake drums in the wheel rims, must be cleaned weekly with alcohol to ensure the optimum braking effect.

+

Never use suds or greasy cleaners.

After cleaning the safety brakes must be checked as described in chapter 6.4

Lining of the climbing foot: Please check regularly whether

the lining of each climbing foot is still sufficient (see chapter 8.8).

Lifting capacity: The stated maximum lifting capacity may not

be exceeded. Please also read chapter 5.1.

You may under no circumstances use the

C

-max to transport goods.

Care and maintenance: Please make sure that you charge the

battery pack after each use of the

C

-max.

When the

C

-max is at a standstill for a while, please turn the device off, i.e. the ON/Off switch needs to be on 0.

If the working elements of the device block, turn the

C

-max off immediately.

+

Repairs may be done by authorized dealers or the manufacturer only. Please exclusively use AAT Alber parts and accessories.

Please note the extensive care and maintenance instructions in chapter 8.

Condition of paths, walkways etc.: Please make sure that

the paths and walkways you use with the

C

6 Instructions for operation

Before we get to the actual instructions for operation, we would like to introduce the

C

-max’s most important components to you:

6.1

Operational components

The control unit is situated on the right handle and consists of an

ON/OFF switch

Ì, an UP/DOWN switch Ê, and a speed control Ë.

6.1.1 ON/OFF switch

During a longer standstill, please turn the

C

-max off by pushing the rocker switch

Ì on “O”.

The

C

-max is equipped with an electronic turn-off mechanism, i.e. if the device is on and not in use for about 5 minutes, it turns itself off automatically.

In such case you need to turn the device first OFF and then ON again.

6.1.2 UP/DOWN switch

With the UP/DOWN switch

Ê you activate the climbing mechanism up- or downstairs.

6.1.3 Speed control

The speed control enables you to adjust the speed continuously.

When you use the

C

-max for the first time, please choose the lowest speed.



13

6.1.4 Control light to indicate malfunction

After turning on the

C

-max the green control light (LED) lights up and remains lit, which indicates that the stair climbing system is in order and ready to use.

Potential malfunction is indicated by a light diode. After a period of

3 seconds each time a blinking signal is repeated.

In case of malfunction, turn the device first off and then on again. If there is still an indication of malfunction, charge the batteries in case of low battery charge. For all other cases of malfunction, please call your local dealer.

6.2

Single step control

The single step switch is located on the climbing frame (see pictures).

Please activate the single step mode to practise and in particular to climb winding stairs.

If you activate the ON/OFF switch in that mode, the device will climb only one step at a time. The climbing system stops in the correct position, even if you press the ON/OFF switch continuously.

The climbing mechanism cannot unintentionally be activated. You can take your time to move the main wheels to the next step’s edge.

+

To continue climbing you simply release the UP/DOWN switch and then press it again.

C

-max

The arrows with the dotted line symbolize the interruption of the climbing process, i.e. the single step mode is activated. To do that you press the rocker switch on I. By contrast, if you press the rocker switch on O it signifies the uninterrupted climbing process, i.e.

the single step mode is OFF.



14

C

-max

6.3

Climbers

The climbers (see picture) must be pulled in to topmost position by means of the UP/DOWN switch if you want to :

• drive on level ground and on slopes

• check the safety brakes

• begin climbing upstairs or downstairs

Before a person sits down on the chair activate the UP/DOWN switch direction UP to move the climbers down until they touch the ground. When the climbers touch the ground they serve as brakes preventing the device from rolling away (also see chapter 6.5.1).

6.4

Check safety brakes

There are safety brakes located on the climbing frame on both sides.

+

Please check the safety brakes each time before you use the

C

-max.

You may check the brake effect either on top of the stairs or on level ground as described in 6.4.1 and 6.4.2.

6.4.1 Test the required brake effect

Tilt the

C

-max backwards until the back rest is in an almost horizontal position (see picture).

If the

C

-max cannot be pushed forward by the handles in said position, but merely rolls backwards, then the required brake effect for the safe operation of the

C

-max is granted (see picture).

6.4.2 Test the required brake effect at the top edge of the stairs

+

Please make this test without a person sitting in the chair.

Tilt the device backwards to its regular climbing position (see chapter 6.8) and drive forward to the first step’s edge. If you cannot push the device over the edge of the step, the required braking effect for a safe operation of the

C

-max is granted.

+

Important: If the required brake effect is not guaranteed, you

may, under no circumstances, use the

C

-max any more. Please contact your local AAT Alber dealer or the manufacturer immediately.



15

C

-max

6.5

Transportation of people with the

C

-max

Please note that the

C

-max was developed to be operated by one person. Always use both hands when using the device.

+

Please practice driving with the

C

-max on level ground, slopes and climbing up- and downstairs at first without a person sitting in the chair! Whenever you practice, please make sure that nobody is standing in the potentially dangerous spot directly below the

C

-max on a slope or stairs.

We suggest that you practice climbing up- and downstairs with the single step mode activated (see chapter 6.2). Also choose the lowest climbing speed for practicing (see chapter 6.1.3)

+

Please do not exceed the maximum lifting capacity (see chapter 5.1)

When seating a person on the

C

-max please be aware of:

6.5.1 Secure stand of the

C

-max

When a person is seated on the

C

-max, the device must stand securely on the ground. Therefore the climbers must be extended in such a way that they touch the ground and support the device (see picture).

Turn the

C

-max on by pressing the ON/OFF switch.

Now activate the UP/DOWN switch direction UP until the climbers touch the ground.

6.5.2 Swivel out or remove the arm rests

When a person is seated, the arm rests can be swivelled out or, if necessary, removed entirely. After the person is seated, please bring the arm rests into their original position.

6.5.3 Fold out the foot rest

When a person is transported, please fold out the foot rest (see picture), and, if necessary, help the person to place his/her feet on it.



16

6.6

Operation on level ground

After the person has been properly seated, you may transport him or her effortlessly on level ground (see picture)

+

Passing over thresholds pulling the

C

-max backwards is much easier than pushing it forwards over them.

C

-max

6.7

Adjust the handles

For climbing stairs or driving on slopes, comfortably and safely, adjust the height of the handles approximately to the level of the operator's shoulders.

+

After adjusting the handles, always make sure that they are securely fastened.



17

6.8

Tilting the stair climbing system

To drive on slopes or to climb stairs you must tilt the

C

-max, which can be done easily by means of the climbers.

1.

Turn on the

C

-max by pressing the ON/OFF switch.

2.

Press the UP/DOWN switch direction DOWN until the climbers lift the main wheels at least 1-2 cm off the floor (see picture).

3.

Put your foot on the power unit’s housing and tilt the

C

-max

slightly toward you until you feel that the

C

-max is balanced.

4.

The

C

-max is balanced if you feel neither pull nor push in the handles.

5.

In order to drive on level ground, the climbers must be pulled in entirely

If you tilt the

C

-max further, or too much, the safety brakes engage and the

C

-max can't be moved forward any more.

C

-max

6.9

Operation on slopes

To drive on a slope, make sure the handles are adjusted appropriately (see chapter 6.7), then tilt the

C

-max slightly backwards (see chapter 6.8).

+

For safety reasons we recommend you to ask another person to assist when driving on a slope..

6.9.1 Downhill

Drive forward to the edge of the slope. In order to slow down you need to tilt the

C

-max a bit more.

6.9.2 Uphill

Please drive backwards up a slope. In order to slow down you need to tilt the

C

-max a bit more.



18

6.10 Climbing upstairs

+

Please always practice climbing stairs without a person and by activating the single step mode plus the lowest climbing speed.

The climbing process can be accomplished quickly and without problems if you adhere closely to the following instructions.

A tip before you start:

+

During the climbing process always pull the

C

-max slightly towards you, so that the device automatically moves to the next higher step.

1.

Adjust the handles to the appropriate height (see chapter

6.7)

7.

The climbing process takes place in two intervals.

The first interval starts by pressing the UP/DOWN switch, direction UP. The climbing process begins here with the power unit initiating the movement of the climbers downward

Ê

C

-max

8.

After the climbers

Ë reach the floor, they assume the load of the main wheels while the main wheels and the frame

Ì are lifted at the same time.



20

9.

The first interval is finished when the main wheels touch down on the next higher step

Í and resume the load of the climbers.

10. The second interval begins by pulling in the climbers

Î. It is finished when the climbers reach their topmost position.

If you activated the single step mode, the climbing process ends at this point. To resume climbing you need to press the UP/DOWN switch once again, direction UP.

C

-max

Because the

C

-max is always pulled slightly backward, it rolls automatically to the next step and reaches the initial position again.

At this point the climbing process repeats itself as described in point 7.



21

6.11 Climbing downstairs

+

Please always practice climbing downstairs without a person, and by activating the single step mode plus the lowest speed.

The descending process can be accomplished quickly and without problems, if you adhere carefully to the following instructions.

1.

5.

Tilt the

C

-max slightly (see chapter 6.8).

6.

Drive the

C

-max forward to the edge of the stairs Ê.

7.

The sensitive rolls

Ë of the brakes keep the

C

-max from rolling over the edge.

C

-max



22

8.

Press the UP/DOWN switch, direction DOWN, and the descending process begins.

9.

The power unit moves the climbers

Ì down.

C

-max

10. When the climbers reach the next lower step

Í, they resume the load of the main wheels, while those plus the climbing frame are lifted off the higher step

Î



23

11. Now the main wheels and the climbing frame are moved forward

Ï

Then the main wheels plus the climbing frame are lowered

Ð by pulling up the climbers

Ñ until...

C

-max

12. ...the main wheels touch down on the next step (see picture).

If you activated the single step mode, the climbers are pulled in entirely and then the descending process ends at this point.

13. Again push the

C

-max all the way to the edge of the step, i.e.

until the sensitive rolls of the security brakes stop the

C

-max.

To continue descending you need to press the UP/DOWN switch again, direction DOWN, if you activated the single step mode.

-max works with batteries and is delivered with one battery pack.

Additional battery packs, we call them quick release battery packs, are available as an accessory.

We recommend an additional battery pack if you use the

C

-max continuously, i.e. there are not sufficient breaks for the batteries to be recharged.

In such case one battery pack is in use while the other is being recharged at the same time.

7.2

Exchange battery pack

1.

Turn off the

C

-max using the ON/OFF switch.

2.

Press the release button

Ê on top of the battery pack Ì until it engages. Now you lift out the battery pack at its grip

Ë from its fixture on top of the power unit's housing

Í.

3.

Push the other fully charged battery pack from the top into its fixture by means of the guiding pins on top of the power unit's housing. This establishes the power connection and locks the battery pack.

+

The quick release battery pack should always be connected to the charger to extend its durability (see chapter 8.2).

+

Please exclusively use the AAT Alber charger to charge your battery pack.

7.3

Charging cable for your vehicle

A charging cable for your vehicle is recommended, if you transport the

C

-max frequently in your car. The charging cable is available as an accessory.

The charging cable's plug

Ê fits into the socket of the car's cigarette lighter; connect the other plug

Ë to the battery pack.

8 Care and maintenance

To guarantee the safety of the

C

-max the device must be inspected every two years, even if there are no outer signs of damage or malfunction.

+

In the interest of your safety repairs of any kind may only be done by personnel authorized by AAT Alber Antriebstechnik

GmbH.

8.1

Charger

Please exclusively use the AAT Alber charger to charge your battery packs.

8.1.1 Automatic charger

The

C

-max comes with the automatic charger. The charging cable's plug

Ê fits into the wall outlet socket; connect the other plug Ë to the battery pack.

This automatic charger recharges your batteries 100%. As soon as the charging process is completed, it switches to a retaining mode, thus overcharging is impossible.

8.1.2 Charging cable

A charging cable for your vehicle is available as an accessory.

Approximately a recharge of 80% is possible by accessing your vehicle’s battery using a charging cable. Connector

Ê fits to the cigarette lighter; plug in connector

Ë at the battery pack.

8.2

Battery pack

The quick release battery pack, consisting of sealed lead acid batteries, should be recharged after each use. (Technical details for the sealed lead acid batteries you find in chapter 8.3)

Tip:

+

If the

C

-max is at a standstill for some time, please connect it to the charger to retain the charge. This does not damage the sealed lead acid batteries, on the contrary, it increases their durability.

8.3

Sealed lead acid batteries

There are 2 sealed lead acid batteries 12 V / 5Ah in the battery pack of the

C

-max. These batteries are sealed, maintenance free, rechargeable and of top quality.

The batteries of your

C

-max can be discharged or recharged in any possible position.

Please avoid a total discharge: The durability of sealed lead acid

batteries depends primarily on the charge/discharge cycle. For instance, you may discharge them partially more than 1000 times and use up the entire capacity more than 200 times, if you avoid a total discharge entirely.

A total discharge does not only lead to a loss of the batteries' capacity, but also shortens their durability. Thus, do avoid a total discharge, by recharging the batteries whenever possible!

+

Charging your batteries is taking good care of them.

Return dead batteries to AAT Alber Antriebstechnik GmbH or take them to particular recycling places where they can be recycled appropriately.

C

-max can be discharged or recharged in any possible position.

3.

Depending of the type of charger used, insert the other plug

Ê into the wall outlet or plug it Ì into the cigarette lighter's socket in your vehicle.

8.5

Fuses

Two electrical 30 A fuses

Ê are located on the side of your battery pack. They are protected by a cover

Ë.

+

You may not mend or by-pass defect fuses. Always replace them with identical ones of the same amperage.

To exchange the fuses, pull out the cover and the fuses, insert the new ones and replace the cover.
