Fig. 4: Description of the lift table HT 600
6.1 Function
The height adjustment of the lifting table is based on the
scissor principle. By actuating the foot pedal down-
wards, the scissors are moved by hydraulic force and
the lift table platform moves upwards. When the foot le-
ver is released, the lift table movement comes to a
standstill and the lift table platform remains in this posi-
tion. By lifting the foot lever, the lift table platform is lo-
wered for the duration of the operation.
The hydraulic power is transmitted via the foot pump to
the hydraulic cylinder. Foot pump and hydraulic cylin-
der are a fixed unit.

verse sequence to the disassembly described above.
9 Operation
CAUTION!
Before operating the lift table, the operator must
ensure that there is no danger from the movement of
the lift platform.
DANGER!
DANGER TO LIFE DUE TO FALLING OF THE
LOAD!
Falling loads can cause serious injury or death. .
- Never exceed the specified maximum load.
- Never move the lifted load.
- Never work under the lifted load.
- Observe the load manufacturer's instructions on
the load application point.
- Distribute the weight centrally on the table of the lift
table
- Only lift loads with the lift table on a horizontal, level
and firm surface.
- Do not lift any persons individually or together with
the load.
- When leaving the workplace, lower the load if it is
not additionally mechanically secured.
Use protective gloves!
Wear safety boots!
Wear protective clothes!

Operation
9.1 Operating conditions
The working area must be dry, fire and explosion pro-
tected and free of corrosive and toxic substances.
The working area must be adequately illuminated.
Dangerous goods such as flammable, toxic or radioac-
tive materials must not be lifted with the lift table.
9.2 Test run
Before operation under load, carry out a test with testing
of all functions without load.
9.3 Using
The lift table can be used for all work which corresponds
to the intended use in the chapter of the same name. It
can therefore be used as work equipment for lifting and
lowering loads, as well as a height-adjustable assembly
table.
The lift table must not be used for work if this does not
correspond to the intended use of the lift table.
In order to protect the wheels and chassis of the lift ta-
ble, no large uneven surfaces (potholes, thresholds,
etc.) should be driven over.
9.4 Load or unload lifting table
When loading or unloading the lift table, the permissible
load balancing must be observed and followed. The
load applied to the lift table must be secured against fal-
ling by suitable equipments. However, it is usually not
necessary to secure the load. It is only necessary for
loads that have an unstable position on the lift platform
(e.g. rolling elements).
Load balancing
The nominal load of the lift table is based on a load
evenly distributed on the platform. If this nominal load is
not evenly distributed on the platform, the nominal load
must be reduced as shown in the figures below.
Evenly distributed:
The load is distributed over the complete platform.
100% of the nominal load is permitted.
Fig. 7: Evenly distributed
Unevenly distributed in transverse direction:
The load is distributed over half of the platform (trans-
verse direction). 50% of the nominal load is permitted.
Fig. 8: Unevenly distributed in transverse direction
NOTE!
- The operating personnel must be familiar with the
operation and functions as well as the safety regu-
lations when operating the lift table.
- The operator must provide the necessary instruc-
tion for the operating personnel.
NOTE!
Check that no component is rusted, damaged or
broken. A lift table with one or more of these cha-
racteristics must not be used.
Without any load on the table, check that the foot
pedal for the hydraulic pump can be moved freely
and smoothly and does not jam at any point in the
adjustment range.

Operation
HT-Series | Version 1.01 15
Unevenly distributed longitudinal direction:
The load is distributed over half of the platform (longitu-
dinal direction). 33% of the nominal load is permitted.
Fig. 9: Unevenly distributed longitudinal direction
9.5 Lifting and lowering the load
Lifting
Before the lift table platform is raised, the lift table must
first be fixed in place by the rollers.
By repeatedly pressing the lever (Fig. 10), the platform
moves upwards. Lock the brakes before lifting and lo-
wering loads.
Fig. 10: Lifting the lift table: HT 300 (top), HT 300 L (bottom)
Fig. 10: Lifting the lift table: HT 600
Make sure that you do not place any body parts (hands,
legs, etc.) under the table when the load is lifted. There
is a high risk of injury!
Lowering
The same requirements that applied in the previous
chapter apply here.
By lifting the lever (Fig. 11) the platform moves down-
wards (HT 300 S, M, M PSR, HT 600).
Fig. 11: Lowering the lift table: HT 300 S, M, M PSR (top),

16 HT-Series | Version 1.01
Care, maintenance and repair
Modell HT 300 L:
When the lever (Fig. 12) is actuated, the platform moves
downwards (HT 300 S, M, M PSR, HT 600).
Fig. 12: Lowering the lift table: HT 300 L
Lifting and lowering the load can be interrupted at any
stage of the operation. The load is held securely in its
current position.
Never work under the lifted load!
When leaving the workplace, lower the load if it is not se-
cured mechanically!
9.6 Moving the lift table
Before the lift table is moved, the load must always be
lowered completely. Furthermore, the load must be se-
cured against slipping and falling before the lift table is
moved.
10 Care, maintenance and repair
10.1 Care by cleaning
The lift table must always be kept in a clean condition.
All plastic and lacquered surfaces should be cleaned
using a soft, damp cloth and a neutral cleaning agent.
Remove any excess lubricant or leaked oil using a dry,
lint-free cloth.
10.2 Maintenance and service/repair
If maintenance or repair work has been carried out on
the lift table, a function test must then be carried out.
- It is forbidden to reach into the lift if it is not secu-
red by the maintenance support.
- Wear suitable protective clothing
- wear safety shoes
Maintenance and repair work may only be carried out by
competent, trained and instructed personnel. Energy
supply systems must be interrupted. If necessary,
further operating instructions must be observed.
Secure the lift table with the maintenance supports:
- Remove load from the lift table
- Folding down the maintenance supports of the lift
table
- Lower the lift table, until the maintenance supports
block the further lowering.
CAUTION!
Risk of crushing!
When the load is lowered, the upper and lower limbs
may be crushed.
- Do not hold the upper and lower limbs between the
load and the ground when the load is lowered.
NOTE!
The operator must have sufficient freedom of move-
ment.
Use protective gloves!
NOTE!
Never use strong cleaning agents for any cleaning
work. This can lead to damage or destroy the device.
ATTENTION!
The mechanical and general condition of the lift
table must be checked by a specialist workshop at
least every 12 months.

Checking the lift table
10.3 Servicing/repair
Infolge von Verschleiß kann es vorkommen, dass an As
a result of wear and tear, maintenance work may have to
be carried out on the lift table.
11 Checking the lift table
The lift table must be checked by a qualified person to
ensure that it is in a safe working condition, in accor-
dance with the provisions of the German Industrial
Safety Regulations and the BGR 500, Chapter 2.10, Pa-
ragraph 2.9, before commissioning and as required at
intervals of no more than 1 year. A person can be regar-
ded as qualified if he / she has at least the qualification
that was previously provided to the expert. The scope of
the test and the inspection deadlines are governed i.a.
according to the results of the risk assessment to be
carried out. Check intervals, the operator can assume
that these measures are sufficient. Type, extent and
deadlines of the tests described in the BGR 500 are pre-
vious practice and comply with the rules of technology.
The test is essentially a visual and functional test. It
covers the examination of the condition of the compo-
nents and equipment, the completeness and effective-
ness of the safety equipment and the completeness of
the test book. If a test period of no more than one year is
adhered to, the operator can assume that this period is
adequate. Verification of scissor lift tables must be veri-
fied by a log book.
