Intended Use
2.7 Personal protective equipment
The personal protective equipment serves to protect
per-sons against impairments of safety and health while
wor-king. The staff member has to wear personal pro-
tec-tive equipment while performing different tasks on
and with the machine which are indicated in the indivi-
dual para-graphs of these instructions.
The personal protective equipment is explained in the
following paragraph:
3 Intended Use
The floor jack is used exclusively for lifting and lowering
of loads, eg. vehicles, up to the maximum specified
load.
The floor jack may only be operated by instructed per-
sons.
Proper use also includes compliance with all information
in this manual. Any use beyond the intended use or
otherwise is considered misuse.
For structural and technical changes to the floor jack the
Company Stürmer Maschinen GmbH assumes no liabi-
lity.
Claims of any kind due to damage due to improper use
are excluded.
3.1 Foreseeable misuse
With the floor jack no reasonably foreseeable misappli-
cations are possible which could lead to dangerous si-
tuations with personal injury if the intended use is obser-
ved.
3.2 Residual risks
Even if all safety regulations are observed, the following
residual risks remain when operating the floor jack.
All persons working with the floor jack must be aware of
these residual risks and follow the instructions to pre-
vent these residual risks from leading to accidents or
damage:
- There is a risk of crushing the lower limbs during
operation.
- During set-up and set-up work, it may be neces-
sary to dismantle protective equipment provided
by the customer. This results in various residual
risks and hazard potentials, which every operator
must be aware of.

Step 2: The pump lever socket is fixed in the lower posi-
tion with a plastic block for transport. Remove
the plastic block before assembly. To do this, in-
sert the pump lever into the socket and push the
socket downwards.
Unscrew screw B until it no longer projects into
the socket.
Then insert the pump lever completely into the
socket and tighten it with screw B in the socket.
Step 3: Check that the pump lever can be moved freely
and easily.

Before the start-up
SRWH-Series | Version 1.01 9
8 Before the start-up
Step 1: Bleed the hydraulic system:
Pull up the pump lever and turn it clockwise to
open the drain valve.
When the lifting arm is fully lowered, pump seve-
ral times with the pump lever to remove the ac-
cumulated air from the hydraulic system. Then
close the drain valve by turning the pump lever
to the left.
Step 2: Carry out a function test without load with the
floor jack. To do this, pump the floor jack up to
the maximum height and then lower it slowly. To
do this, open the drain valve.
- If the lifting arm cannot be pumped to the maxi-
mum height with a maximum of 7 pumping mo-
Place the floor jack on a level and firm surface
and place the front part of the floor jack at least
500 mm higher than the end part of the floor jack
(Fig. 7).
Fig. 7: Venting the hydraulic system
- Open the bleed valve and use the pump lever to
remove the collected air from the hydraulic sy-
stem by 4 full strokes.
- Lower the floor jack and place it in the horizontal
position. Close the bleed valve.
Step 4: Check all parts for integrity and proper function.
9 Operation
DANGER!
Danger to life due to falling of the load!
Falling loads can cause serious injury or death.
- Never exceed the specified maximum load stride.
- Never move the lifted load.
- Never work under the lifted load without this being
additionally secured by racks.
- At the point of attachment of the floor jack to the
load observe the instructions of the manufacturer
of the load.
- Distribute the weight centrally on the saddle of the
floor jack.
- Only lift loads with the floor jack on horizontal, level
and firm ground.
- For vehicles to be lifted, place the wheels straight
and block with sufficiently dimensioned wedges.
- Do not lift any persons individually or together with
the load.
- When leaving the workstation, lower the load if it is
not additionally secured with racks.
CAUTION!
Risk of crushing!
If improper work is carried out on the floor jack, there
is a risk of injury to fingers, hands and feet.
Use protective gloves!
Wear sagety boots!
Wear protective clothes!
NOTE!
- Operating personnel must be familiar with the ope-
ration und function of the floor jack and the safety
regulations pertaining to it.
- The operator is responsible for ensuring that all
operating personnel have had necessary training.

Operation
9.1 Operating conditions
The working area must be dry, fire and explosion pro-
tected and free of corrosive and toxic substances.
Dangerous materials such as fire-liquid, toxic or radi-
oactive materials must not be lifted with the floor jack.
9.2 Test run
Before operation under load, carry out a test with testing
of all functions without load.
9.3 Lift the load
Step 1: Check that the load to be lifted is on a level and
firm surface, lock the wheels on vehicles and
apply the handbrake.
Step 2: Slide the floor jack under a lifting point of the
load intended for the floor jack (follow the manu-
facturer's instructions!).
Step 3: Turn the pump lever about its own axis to the
right (clockwise) to close the drain valve.
Step 4: To lift the load, perform an even pumping move-
ment with the pump lever by alternately moving
the pump lever up and down. The lifting arm
swings upwards.
Step 5: Before the lifting arm touches the load, check
again the alignment of the jack-saddle to the
load pick-up point. Make sure that the weight is
distributed centrally on the jack saddle.
Step 6: Lift the load slowly and evenly to the desired
height.
Step 7: Place the support frames under the load and
slowly lower the load onto the support frames by
slowly turning the pump lever counterclockwise
to open the drain valve.
9.4 Lower the load
Step 1: Turn the pump lever about its own axis to the
right (clockwise) to close the drain valve. Pump
the lifting arm upwards against the load and lift
the load off the pedestals. Pull out the stands
under the load.
Step 2: Slowly turn the pump lever to the left (counter-
clockwise) about its own axis to open the drain
valve.
The more you open the drain valve, the faster
the drain speed will be.
Step 3: When the load touches the floor, close the drain
valve and check that the load is stable. Then re-
lease the floor jack completely by opening the
release valve again and pull the floor jack out
under the load.
Step 4: Turn the pump lever all the way to the left (coun-
terclockwise) to open the drain valve. Apply
force to the lift arm to move it down to the stop-
per.

the upper and lower limbs.
- Do not hold the upper and lower limbs between the
load and the ground when setting down the load.
