3 - Stairmatic - Operating Instructions

You must be a physically and mentally capable adult to operate the Stairmatic and haveachieved a competent operating level before you use the Stairmatic to carry a passenger,where possible BARONMEAD training is advised.

Please read these instructions carefully and ensure you are fully familiar with the Stairmaticbefore use. (If you have a training dvd, use with these notes).

3.1 General

The operating technique is to lean the Stairmaticback and let the machine do the lifting.

First familiarise yourself with the machine bystanding on a flat surface and tilting the machineback towards you. At a point about 20 degreesfrom the vertical the machine is “in balance” withlittle weight being transferred to your arms orwrists. This is the point of balance referred to inthese instructions.

Practice sessions should be held on a regularbasis. Monthly practice is advised as a minimum.

Check that the stair surfaces are secure and freefrom obstructions. Ensure that the nosings aresecure. Some nosings are very wide and theStairmatic may feel like it has arrived at the stepedge when the main wheels reach the back edgeof the nosing. (The Step Edge Sensor (referred to from here as SES) feature (where fitted) willnot allow the machine to drive down until the brakes are correctly locating the machine at thestep edge.)

Before using the Stairmatic with a passenger for the first time it is recommend that theoperator practices with the machine empty until the operating principals are understoodand confidence is gained in its use.

Page 6

3.2 Preparation

After a number of practice runs up and down the stairs with the Stairmatic empty, try thesame process with an able bodied volunteer of a similar weight to the operator. You will findthat the most comfortable tilt position will vary slightly due to the additional weight. First, getthe feel for the point of balance on level ground before approaching the first step. Keeping afirm hold on the handle, proceed as you have previously practiced until a comfortabletechnique is achieved.

In the early stages of learning with awkward staircases, or with nervous or heavy passengers,it is recommended that two people use the Stairmatic. The second member of the teamstands below the machine ensuring the machine is in the correct position on the step andreassuring the passenger. Repeat this procedure until you are confident

If a trained operative is available have a ride yourself so that you can appreciate the ride fromthe passengers’ point of view. Remember your confidence will transfer itself to the rider.

Before transferring the passenger, prepare the Stairmatic:

n Examine the machine before use; check the clamps are correctly adjusted (Section 9.4.10),check brake pad wear is within acceptable limits (Section 9.4.11), check chains are straightand undamaged.

n Establish that the passenger to be carried is within the capacity of the machine. (Refer tosection 3.11). It is recommended that only experienced and competent users attempt to carrypassengers significantly exceeding their own weight.

n Switch the machine on (and check for a steady status LED, SM10a - 12 see schematic)

n Lift up the arm rest where needed.

n Undo the seat harness.

n If necessary, raise the footrest.

n Transfer the passenger to the Stairmatic.

n Once the passenger is seated comfortably, fold down the arm rest.

n Secure the harness and adjust to a suitable tension.

n Release the foot rest lever, lower the foot rest and tilt the Stairmatic back to lock the footrest in place.

3.3 On the Level

On a level surface use the Stairmatic upright. Hold the machinewith one hand on the top handle and the other on the lowerhandle, it can then be manouvered on the level. If the surface isuneven or very soft it may be easier to first tilt the Stairmatic at acomfortable angle before moving. Sometimes it is easier to pullthe Stairmatic backwards rather than push forwards.

3.4 Going up Stairs

Approaching the stairs to go up:

n Pull the Stairmatic backwards to the first step.

n Make sure that the lift wheels, which are attached to the chainsat the rear of the chair, are high enough to clear the front of the step,if not, lean back and drive the machine “UP” until the lift arms liftand lower, bringing the next pair of arms to the top (See diagram 3).

n Pull the machine back so that both the stair glides are restingagainst the nose of the step (See diagram 4).

The “Up” and “Down” controls are immobilised in theupright position. This is to remind you that the Stairmatic is to beused in the correct ‘tilted back’ position.

To tilt the Stairmatic back to the point of balance and at acomfortable angle you will need be up a few steps. Usually this isabout three steps. See diagrams 1 & 4)

The machine is now ready to climb the stairs.

n Hold the machine firmly with the machine leant backslightly beyond the balance position and press and hold the “UP” button. Press down onthe handle at the start of the lift cycle.

n The lift wheels raise the Stairmatic on to the next step whilst the operator maintains thecorrect balance position.

n As the machine climbs each step it is necessary for you to move up with the machine.

When the Stairmatic lands on each step draw the machine back against the nose of the nextstep ready to climb again. Be sure to maintain the correct angle of tilt.

Page 8

n On the top three steps, maintain the angle of the machine until the top step is reachedwhere the top and lower handles can be used to move the machine fully away from the topstep before returning it to the upright position.

The technique will soon be developed into a smooth and continuous motion.

When first driven “UP”, the machine may try to return to the vertical position.To counteract this as the machine starts to lift, downward pressure should be applied to the handle.This effect can be reduced by increasing the angle of tilt until balance is reached while lifting.

Always maintain a firm hold on the handle.

When you reach the top of the stairs pull the Stairmatic fully away from the edge usingthe lower handle for control, then ease the machine into an upright position.

3.5 To Go Down Stairs

First, before approaching the edge of the stairs, tilt the Stairmatic back slightlybeyond the point of balance - the same angle used when ascending. Practice this to ensureyou are not carrying too much weight on your arms and wrists.Use the top and lower handles (as in diagram 5).

n Push the Stairmatic slowly forward until you feel it stop atthe stair edge (See diagram 6). The braking system actsautomatically on the edge of each step. (Once the brakeshave reached the edge of the step the SES (where fitted) will

activate and allow themachine to be driven down tothe next step).

n Maintaining the correctangle of tilt, place both yourhands on the top handle, press the “DOWN” button and themachine will lift and lower to the next step, stay close to themachine so, as it lands it rests against your body (as themachine lands the speed will ramp down to stop until the nextstep edge is sensed, SES machines only).

Page 9

n Push the machine forward to the edge of the next step, again the brakes lock (and the SESwill allow the machine to be driven down).

n Press “DOWN” and again the Stairmatic will lift and lower.

Practice this to obtain a smooth and continuous action down the stairs. (Once the bottom ofthe stairs is reached the SES will stop the machine from driving until the next downward stepedge is sensed.)

3.6 Practice

After initial training, practice sessions should be held on a regular basis. Monthly practice isadvised to ensure continued familiarity. If the operator has not used the machine recently, startempty again to familiarise yourself before attempting to carry a passenger.


Page 10

There may be occasions when the Stairmatic is required to negotiate unusual stairs, seesection 7 for more details on dimensions required.

3.7 Fan shaped stairs

To check whether the Stairmatic CAN be used first try it without a passenger. Tooperate the Stairmatic on a fan shape the same principals of operation apply. It will beobvious that the machine has to be turned on each step of the fan. On the way up, makesure that both the stair glides are pulled back tight against the nose of each step (see diagram3). On the way down, (the SES will stop the machine from driving down unless) both brakesare (sensing) on each step edge.

If there is insufficient stair tread for the brakes to operate then the Stairmatic must notbe used. In order for the brakes to lock the Stairmatic normally needs a minimum tread depthof about 175mm (see stair tread requirement - Section 7). To get this dimension on a fan it isnecessary to keep some distance away from the centre of the fan, but care must be taken thatthe footrest does not make contact with the facing wall or stairway, or the handle with theadjacent wall.

3.8 Landings

To check whether the Stairmatic can be used first try it without a passenger. Tonegotiate a small landing with a right angle turn using the Stairmatic requires a slightlydifferent technique. Going up, as the machine reaches the top step onto the landing theoperative should stand to the side of the machine in the direction of travel, still maintainingthe correct angle of tilt. Place one hand on the lower handle and draw the Stairmatic backfrom the step and at the same time draw it round to approach the next flight of steps. Unlessyou are on a particularly wide staircase it is advisable to stay close to the inside of thestaircase to allow clearance on the turn.

Coming down the stairs to the landing is the reverse procedure. Stand to the side ofthe Stairmatic from the direction of travel, align the machine correctly on the top step of the nextflight of stairs. Both brakes must be locked on the edge of the top step before (the SES will allowthe machine to be) driven down. It is advisable to drive down one step, stop and keeping themachine in the balance position, move square behind the machine before continuing.

Note: Each stair has different obstructions, (Radiators, Windows, and Banisters). Eachstaircase needs evaluating to determine the Stairmatic’s suitability.

3.9 Key Points

A) The operator must follow the manufacturer’s instructions to use theStairmatic safely.

B). The operator should wear suitable footwear and clothing when usingthe Stairmatic.

C). Do not allow the seat harness or loose clothing to become entangled in thelift chains.

D). Do not attempt to manoeuvre the machine from side to side while the chain liftwheels are in contact with the stairs as damage can occur to the lift mechanism.

E). Extra caution is required on wet, slippery and unsound surfaces, be extravigilant in these circumstances (See section 2).

F). In the event of a EMERGENCY on the stairs, where possible, return to thetop or bottom of the stairs. If this is not possible, drive the Stairmatic onto the chain lift wheels and lay on stairs in its EMERGENCY POSITION as shown in diagram 7, and seek assistance. Do not leave the rider unattended in the machine.

G). Make sure children, pets and other distractions are kept safely away whilethe machine is in use.

H) The operator should always stand behind the Stairmatic when in use on thestairs, unless dealing with a limited space staircase.

3.10 Review

Tilt the machine slightly beyond the point of balance before approaching the steps,either up or down.

Do not try to operate the Stairmatic vertically, when, as a safeguard, the up/downcontrol will not operate, also do not incline the Stairmatic too far back.

When going up, maintain the angle of tilt and make sure the machine is pulled backagainst each step before driving up.

If the audio alarm sounds when the machine is in use, finish the current trip andrecharge before next use (SES only).

When going down, tilt the Stairmatic to the balanced position well beforeapproaching the top step. Do not drive down unless pushed forward onto the brakes.(The SES will inhibit drive until it has sensed the edge of each step).

Always keep a firm hold on the handle with both hands, evenwhen pressing the up/down control.

And remember, your confidence will transfer itself to thepassenger.

The Stairmatic SM10A - SM12 SES are fitted with a low batterywarning that will flash & sound when the batteries requirerecharging. When low battery is indicated, finish the current tripand recharge before next use. Although the Stairmatic iscapable of many hundreds of steps* on a single charge,

charging when not in use is advised for maximum battery life. Other machines - charge whennot in use (see section 4).

3.11 Security Features

The Stairmatic SM10a - SM12 SES’s have a red Emergency Stop switch located on the tophandle. This in conjunction with the controller will stop the motor driving.

A key switch is fitted to the Stairmatic to prevent unauthorised use. The machine is “on” when the key is horizontal and the LED is illuminated (SM10a - SM12)

The maximum load on the Stairmatic SM10a - 12 is 130 Kgs. (20 stone), Mk7 - 10 is115Kg (18 stone).

If machine is obstructed or overloaded, an overload cut-out may activate. Once the cause ofthe overload has been removed, the cut-out can be re-engaged by pressing the “trip” switchon the control panel (see section 6).The SM10a - SM12 controller has an auto-resetting current limiter that may temporarily stopthe machine under overload conditions.

3.12 Transportation and Disassembly

Should you wish to transport the Stairmatic there are several ways of doing this.

n First, the chain lift wheels must be driven to the north-south (top-bottom) position out ofthe way to prevent them being damaged. The machine can now be transported laid on itsback or upright (where possible). Refer to you particular vehicle manual to secure for transit.

n Alternatively the Stairmatic can be separated into two parts. First, drive the chain lift wheelsto “north - south”, then unplug the seat control cable plug from the control panel of the baseunit, then undo the four seat clamps, two on each side, and lift off the seat. Refitting is thereverse of this procedure. Take care to ensure that the plug locates correctly in the socketduring reconnection and the seat clamps are correctly adjusted - refer to the section 9.4.10.


Page 14

3.13 Storage and Batteries

When the Stairmatic is not in use, store the machine in a dry, sheltered environment.

Switch the machine off, using the charger / lead supplied, connect it to the socket on the controlpanel, Switch on and observe that the red charger-on light is showing. When charging iscomplete, the green light shows (Refer to the charger instructions for your model - section 4).

Do not use chargers outside.

The Batteries are sealed units and require no maintenance other than regular charging. Donot use unapproved battery chargers as these may damage the batteries. It is bad practiceto let the batteries become heavily discharged, as this will shorten the battery life. If lowbatteries are indicated, switch off and recharge the machine as soon as possible.

SM10a - 12; The status indicator and battery alarm fitted to the Stairmatic SES’s showswhen the battery voltage drops below a set level. A slow flash and beep indicates this.Recharge the machine as soon as practically possible after low batteries are indicated.

As the batteries get old, the capacity will be reduced and it will be capable of less work. Thiswill correspond to a reduction of time before low batteries are indicated. If the batteries areslow after a full charge and the alarm sounds / status LED flashes soon after commencing usethis indicates very low battery capacity, the batteries have ended their useful life. If, whenascending, it becomes obvious that there is insufficient power - do not continue. Rest thebatteries for a short while to let them recover some capacity, then descend as normal. Putthe machine on charge immediately.

If a fast flash is observed, this indicates a system fault. The most common faults are batteryrelated and if the drive switch is activated when switched on. Switch the machine off and onagain to see if the fault clears.

4 - Battery Charging Instruction

The Stairmatic Stair Climbers are powered by AGM sealed for life, lead acid type batteries. Toget maximum life from the batteries they should be kept in a high state of charge. Regulardeep discharges will dramatically reduce battery life. If the machine is not in use, chargebefore storing and again before next use (up to 3 months storage) or leave on chargepermanently so the machine is always ready for use, see recommended charging intervals foryour machine, this option reduces the risk of the damaging the batteries through insufficientcharging. Do not leave the machine switched on. If the low battery alarm sounds / status LEDflashes recharge as soon as possible (SM10a - SM12).

Instructions for use - Connect charger output / lead to Stairmatic Charger socket (Basecontrol panel) Connect charger to Mains supply then switch on. To get Maximum life fromthe battery, refer to recommended charging intervals.
