1.4 Residual risks
The sharp blade of the trimmer cancause injury.
Remain focused and act with caution when
working with the trimmer. Always wear personal
protective equipment.
A faulty compressed air connection and a high
proportion of water in the pressure line may
cause a jet of water escaping at the connection
point. Therefore, ensure that the hose
connection is correct and that the water content
in the pressure line is as low as possible (drain
the water separator regularly). The water trap
doesnot form part of the machine and has to be
installed upline of the machine.

the power cable of the electric motor can be laid
upwards without any risk of kinking.
1. Attach the electric motor to the overhead
suspension system
ATTENTION
Device damage!
Comply with the minimum load
bearing capacity of 15 kg
2. Setting up an ergonomic workplace:
The following illustration shows the optimum
distances as determined by S&W.
It may be necessary to adapt these values to
your specific workplace situation.
Ergonomic workplace
3. Check whether the electric motor is
switched off.
Position OFF
4. For connection to the power supply, see

4. Pull slightly in order to check whether the
shaft is properly locked and protected
against accidental disconnection
The trimmer is now ready for use.
4.2.4 Connecting the pneumatic trimmer
(EFA Trimmer 90D and EFA Trimmer 130D)
ATTENTION
Device damage!
Operate the trimmer only with clean,
anhydrous, and oiled air!
Pneumatic hose connection
1. Insert the pneumatic hose (1) into the
screw connection (2) on the valve housing
(3) of the trimmer up to the stop.
2. Pass the exhaust hose (4) through union
nut (5) and slide it onto the valve housing
of the trimmer.
3. Screw the union nut to the valve housing
of the trimmer.
4. Screw one-hand coupling (6) (with sealing
ring) into maintenance unit (7) (with filter
pressure reducer). Make sure to assemble
the maintenance unit in the following order:
Water separator (8), pressure gauge (9),
oil mist blower (10).
5. Insert plug nipple (11) into coupling
To ensure lubrication of the pneumatics motor,
the maintenance unit must be set to 1-2 drops
of oil per minute (or one drop of oil for
approximately 15 cuts).
A faulty compressed air connection and a high
proportion of water in the compressed air may
cause water to escape at the connection point.
Therefore, ensure that the hose connection is
correct and that the water content in the
compressedair is low(drain thewater separator
regularly).
If no dried air is available, the customer must
install a water absorber.
4.2.5 Filter pressure reducer
The air from compressed-air systems is usually
contaminated and has accumulated moisture.
Therefore, a filter pressure reducer with water
separator must be installed between the
compressed air system and the tool. This not
only controls the operating pressure but cleans
and drains the compressed air. In addition, this
improves on the usefulness and increases the
service life of the pneumatic trimmer
significantly.
The filter pressure reducer should be installed
as close as possible to the pneumatic trimmer.
Set the operating pressure on the filter
pressure reducer to max. 6 bar.
You can purchase a suitable filter pressure
reducer on request from our sales department
at Schmid & Wezel.

7.2 Sharpening the blade
ATTENTION
Incorrectly sharpened blades lead to
production losses and endanger the
user.

If the trimmer is operated without a sharpening
unit (special accessory), the blade is sharpened
with whetting steel.

1. Hold the trimmer (1) with the guide hand,
2. Hold whetting steel (2) with your free hand
in a horizontal position
3. Start and carefully move the trimmer with
the rotating blade (3) slowly back and forth
on the whetting steel
During whetting, ensure that the knife has full
contact with the whetting steel.
ATTENTION
Do not use force as parts could be
damaged!
7.2.2 Sharpening
Heavily worn trimmer blades are usually
sharpened by Schmid & Wezel GmbH.
We can also provide a quotation for a suitable
grinding machine.
7.3 Advanced Maintenance

The flexible shaft is enclosed in a protective
sleeve.
1. Pull the shaft core out of the protective
sleeve
2. Place the shaft core on a suitable base
and spray from all sides, turning it several
times.
Use EFA special grease spray
3. Let the grease set briefly and push the
shaft back into the protective sleeve.
7.3.2 Lubricants
Unintentional contact with the processed
product (food) cannot be ruled out with
certainty. Therefore, only use suitable
lubricants.

for your machine from the sales department of
Schmid & Wezel.
7.3.3 Maintenance unit
For proper operation and to maintain the
adequate service life of the pneumatic
