Cleaning And Care Of Stainless Steel; Behavior In Cases Of Error; Moving Onto An Obstacle; Emergency Discharge During Blackout - Nussbaum SPRINTER MOBIL 2500 Instrucciones De Servicio

Under adverse circumstances, weekly system cleaning might be required,
however a monthly cleaning may be sufficient.
Do not use and aggressive and abrasive materials for cleaning, rather use
mild cleaners, e.g. a commercially available detergent and luke warm
water.
• For cleaning, do not use high pressure washers (e.g. steam cleaners).
• Carefully remove all contamination with a sponge, or if required with a
brush.
• Make sure that there is no residue of the cleaner on the system.
• Dry the system with a cloth and spray it with a spray wax or oil.

Cleaning and care of stainless steel

In all cases after assembly, a first cleaning should be done with our stainless
steel cleaner. We recommend our stainless steel cleaning spray (1) for this.
Immediately remove iron particles, grinding dust, swarf, and weld spatter.
These foreign bodies can accelerate rust if they are deposited on the stain-
less steel surface. The passive layer of the non-corroding steel is broken and
this leads to pinhole corrosion.
To guarantee a perfect stainless steel, in principle we recommend regu-
lar cleaning and care of stainless steel in exterior areas (at best every 6
months).
Contamination and deposits
occurred or severe corrosive etching can be removed with our special
„Pelox" cleaner (2).
For stainless steel products that are placed close to seawater, seawater
resistant products can be implemented in V4A quality.
Detailed information can be found under www.edelstahl-rostfrei.de.
All stainless steel parts from the Feldmann product range are made from
V2A or V4A with material numbers 1.4301 or 1.4401104. The surface is
ground (mostly 240 grit).
Despite the „rust-free" specification, stainless steel parts can rust!
Stainless steel stands for a guarantee for long lifetime and elegance. To
permanently retain the high value of the surface, it is indispensable to take
care of and protect the material regularly.
Rust bloom can occur due to environmental influences or improper treat-
ment.
How does rust bloom occur?
Environment related:
• For higher humidity with salt content close to salt water.
• In industrial areas with particularly aggressive air contamination (acid
rain).
• By surfaces in contact with de-icing salt spray water close to streets.
• By contact with chlorine water (V2A is not suitable for swimming pools).
Assembly related:
• During processing with tools that are in contact with normal iron.
• From flying sparks that occur e.g. due to grinding of the surface.
• When the surface comes into contact with building-chemical related
foreign materials (calcium, cement dust, etc.) that deposit on the sur-
face.
• Aggressive cleaning materials.
1. Cleaner spray 7064-PF cleans, cares for and protects stainless steel
parts.
2. Pelox 7065-PE special cleaner for the strongest contamination, films
and corrosion.
3. Cleaner and preservative 50-ESP cleans and protects (long term pro-
tection).

Behavior in cases of error

Defective operational readiness of the system may be due to a simple
error. Check the system for the listed sources of error.
If the error cannot be removed after an inspection to the named causes,
then inform customer service or your dealer.
Problem: Motor does not start
Possible causes:
No power supply
The main switch (2) is not switched on, or is
defective
Defective fuse
"LIFT" (3) button defective
Motor defective
Problem: Motor starts, load is not lifted
Possible causes:
Load is too heavy
Hydraulic oil filling level is too low
Emergency discharge fixture is not clo-
sed
Pressure line leaking
The connector for the left is designed for a
clockwise phase order.
Problem: The lift cannot be lowered
Possible causes:
Lifting table is sitting on an obstacle
Hydraulic valve defective
"LOWER" (4) button defective
Incorrect push button actuated
7.1

Moving onto an obstacle

If the system moves onto an obstacle during lowering, then it remains in po-
sition due to the mechanical resistance. In this case the lift must be moved
upwards by pushing the "LIFT" (3) button on the operating panel until the
obstacle can be removed. Afterwards the lift is in a normal work condition
and can continue to be operated as described in the operating manual.
7.2

Emergency discharge during blackout

An emergency discharge is an access into the system
controls and may only be done by experienced speci-
alists.
The emergency discharge must be done in the fol-
lowing described sequence, otherwise it can lead to
damage and hazard to life and limb.
Any kind of external leakage is not permitted and must
immediately taken care of. This is absolutely necessary
especially before an emergency discharge.
Reason which make
necessary are for example, electrical blackout, for errors in the lowering
valves, etc.
1. Switch off the main switch (2)
2. Loosen and remove the front unit covers (1).
3. Valve pins V1 and V2 must be pushed from above simultaneously
using a suitable (e.g. screwdriver).
Remedy:
Check the power supply
Check the main switch (2).
Have fuses checked
Inform customer service

Remedy:
Unload the lift
Refill hydraulic oil
