2.2 SAFETY MEASURES
Start exercising with a low-weight load only. As soon as you are perfectly handling the system1.
of LIFTKAR, you can increase the weight up to full load.
Keep out of the danger area beneath the cargo.2.
The load has to be fastened at the frame of LIFTKAR by the strap bar.3.
Lifting the load on level ground (that means without steps) only by switching direction UP4.
(see picture A, chapter 4). Till maximum height is reached! Descending by switch direction
DOWN (see picture A, chapter 4).Do not descend by switching direction UP: that means: After
having reached the maximum height the switch direction UP must not be used further, as
undesirable accelerations could occur.
For maintenance work and repairing you must remove the battery unit.5.
Wear only working clothes and shoes in due order to avoid injuries and accidents caused by6.
stumbling over or being caught.
3 STARTING OPERATION
Put the charged battery unit in its place and insert the plug.
The yellow control LED at the cover of the motor unit is lightning.
The crank drive system is switched on by pressing the tumbler switch at the upper or lower handhold (see
picture A).
Always pull out the plug after use!
If the plug socket remains inserted more than 24 hours, there is a risk of discharging too much and the batteries
could be permanently damaged.

3.1 SYSTEM OF GOING DOWNSTAIRS
(Pictures in order 1 to 6)
Moving to a safe distance from the step margin - (4-10 cm distance wheel shaft to step margin) then STOP!
Actuate the switch (arrow forward).
The crank drive system with the small support wheels moves forward and reaches over to the next step below.
As soon as LIFTKAR is lifting, the permanently braked support wheels pull the hand truck forward over the step
margin and LIFTKAR is descending under controlled balance.
IMPORTANT
Moving to 4 - 10 cm to the step margin and STOP!1.
As soon as LIFTKAR is lifting, let it go. Do not pull back too strongly!2.
On winding stairs: LIFTKAR has to be turned a bit on each step so that both wheels are stopped3.
at the same distance from the step margin.
GENERAL REMARK
Always try to find the balance.
As soon as you have this under control you will see, how easy it is to work with LIFTKAR.
3.2 SYSTEM OF GOING UPSTAIRS
(Pictures of chapter 4.1 in order 6 to 1)
Pull back to the step margin of the next step above. By actuating the switch (arrow backward) the crank drive
with the support wheels is extending backward and is lifting LIFTKAR to the next step above.
Always pull back to the step margin. On winding stairs both wheels have to be pulled back to1.
the step margin on each step. After short exercising the switch could be pressed permanently
making it possible to work permanently and quickly.
Minimum tire pressure 2.5 bar.2.

4 AUTOMATIC BRAKE
For the LIFTKAR model MTK 310 the automatic brake on the main wheels is part of the standard equipment.
For the model MTK 190 this brake is available as additional accessory.
It can be built in afterwards.
There are 3 positions of the brake:
Free-wheel brake (backward free-wheel / forward braked) for going upstairs safely.1.
Neutral position for driving on level ground.2.
Automatic brake at the step margin for going downstairs safely.3.
Switching on the free-wheel brake from the neutral position:
Push by foot ... or by hand
IMPORTANT
Minimum tyre pressure 2.5 bar because of ground clearance.

Switching on the step margin-brake from the neutral position:
Push up the handle LIFTKAR braked at the step margin
IMPORTANT
When the step margin-brake is switched on, do not make strong turnings on level ground or on1.
stair landings.
On rough ground or at grated stairs there could occur damage to the plastic running wheels of
the brake.
If you pull LIFTKAR back too much when going downstairs, it is possible that the step margin2.
brake will continuously brake on stairs with low steps.
To release the brake you have to put LIFTKAR in a more upright position.
From step margin-brake back to neutral position:
Push the back wheel of the brake forward Turning further by foot or hand to neutral position.
(Then the middle wheel of the 3 brake wheels is
stopped by a cam on the frame- when turning the
brake anti- clockwise.)

Liftkar MTK I 9
From the free-wheel brake back to neutral position:
Switching the brake back to neutral position by foot or by
hand. IMPORTANT
If you want to go upstairs with the
brake switched on, the brake has to be
switched on before you pull the
LIFTKAR to the first step margin. If you
pull the wheels to the step margin first
and then switch on the brake it may
occur that the brakes spring back to
neutral position.
Note:
If there is too little ground clearance for the foot, then lift LIFTKAR a bit by the lifting system.
5 OPERATING INSTRUCTIONS
For high loads such as drink
dispensers
For low loads such as washing
machines
For easier lifting of heavy loads put
the shaft of the supporting wheels
backward. Then push the foot on it!

Liftkar MTK I 10
Stop position at the stair
IMPORTANT
When going down with inclined frame, please note: You are
still standing on the stair landing, holding the upper
handholds. The lifting system is strongly inclined
backwards. On higher steps this may cause that the
supporting wheels do not touch the next step below
immediately. Therefore LIFTKAR cannot be lifted from the
upper step to the next step below. Then the supporting
wheels are partially already moving backwards. So the
cargo is not lifted completely. The handtruck could move
downwards uncontrolled to the next step below. When
starting to go downstairs it is therefore important to hold
the handtruck as upright as possible and keep the balance.
This situation should definitely be exercised on the spot.
The point of balance can be changed by inclining the frame. Please take care that the working angle of the
lifting system is changed as well when inclining the frame. This makes the maximum step height lower. This is
also important when you are already on the stair landing and the handtruck still has to go up the last step.
6 GROUPS OF ACCESSORIES
Accessories I - standard
Accessories II - additionally available
6.1 ACCESSORIES I
6.1.1 QUICK-CHANGE BATTERY BU
The quick-change battery unit includes 2 pieces of gel-sealed,
maintenance-free lead batteries 7 Ah-12V which are connected in series.
Maximum charging current: 2.7 Ampere. Lead batteries are continuously
discharging a bit even when they are not used. Therefore it is
recommended to recharge the batteries once a month even when they
are not used. If the batteries of the battery unit have to be exchanged, it
is absolutely necessary to connect „+“and „–“correctly. In case of wrong
connection the electronic power switch will be damaged.

Liftkar MTK I 11
6.1.2 BATTERY CHARGER
The battery charger supplied is extremely powerful. An LED display gives
a clear indication of charging status. The charge indicator gives you an
idea whether the battery pack is fully charged or not. It is worth checking
that the battery pack is fully charged before using the Liftkar.
Technical data
Mains voltage supply (50/60 Hz, 0,7A): 100-240 V AC
Nominal rating (input): 24 W
Charging voltage: 24 V DC
Theoretical charging current: 1,0
Protection class: IPX4
Safety approval: UL, cUL, CE
The charge status is displayed as follows by a LED:
If the LED is lit continuous red the battery pack is being charged.
If the LED is lit continuous green the battery pack is fully charged. The charger can be left connected to the
batteries after full charge (green light), without harming the batteries. The charger uses minimum power in
this stand-by mode, (after battery is fully charged), maintains the batteries at full charge and extends battery
life. This is accomplished with electronic circuitry that controls and regulates the amount of charging current
that is sent from the charger to the battery being charged
SAFETY GUIDELINES
Please note the following:
Protect against damp
Only charge in a well ventilated room
Do not pull the plug out of the socket by its cord
Do not operate charger with damaged cord or plug - replace immediately!
6.1.3 USE ONLY FOR THE PURPOSE INTENDED
The charger unit is designed exclusively for charging lead-acid batteries containing liquid, gel-type and
fabric-type electrolyte
It is not permissible to charge NiCd or NiMH batteries or primary cells.

6.1.4 FASTENING STRAP WITH RATCHET-DRILL +
PLASTIC- COVERED HOOK MODEL SB 3.5 M
For quick, reliable fastening of the load.
6.2 ACCESSORIES II
Quick battery charger BC 10-30 VDC1.
It makes the continuous use of LIFTKAR possible by recharging in the
truck or van. Even when the motor is not running, the batteries can be
charged. The time for one full charge is 4-8hours. This battery charger
is specially made for the capacity of the batteries, that means that the
required charging current and charging voltage are never
exceeded.(Direct charging by 24 Volt electric tension of the truck
would reduce the durability enormously because the generator
capacity of the truck is too high for these small batteries.)
Shovel attachment with 2 swivel castors model SA2.
It is simply fixed to the shovel and secured by a spring cotter.
Under the edge at the front there are 2 swivel castors; made from nylon (75x32 mm).The transport of bulky
and heavy loads is made much easier. The load remains a bit tilted. On level ground you can go on 4 wheels.
The turning on narrow stair landings is easy and safe.

Battery check on damages of the covering.D.
8.1 DIRECTIONS FOR USING THE BATTERIES
The batteries of the stairclimber are completely closed, maintenance-free gel- sealed lead batteries. 2 units with
12 V each connected in series. Recycling like car batteries.
NOTE
The battery is lasting very long, if you pay attention to the following:
Charge the battery unit after each use.
Use only the original battery chargers. These are charging with the right tension and current
Overcharging is not possible with these battery chargers.
If the stairclimber is not used for a longer time, charge the battery unit at least once a month.
Never discharge the battery unit completely. In case of a decrease of capacity take a full-
charged battery unit for further working. Charge the discharged battery unit immediately.
The best temperature for charging is room temperature.
Keep the battery unit dry and cool.
