hose (2) to the maintenance unit (3) (with
filter pressure reducer). Make sure to
assemble the maintenance unit in the
following order: Water separator (4),
pressure gauge (5), oil mist blower (6).
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
compressed air is low (drain the water
separator regularly).
If no dried air is available, the customer must
install a water absorber.
Before connection, remove impurities by
blowing air through the compressed air
hose using a compressed air gun.
4.2.2
Filter pressure reducer
The air from compressed-air systems is usually
contaminated and has accumulated moisture.
Therefore, a filter pressure reducer with water
separator should 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 circular saw
significantly.
The filter pressure reducer should be installed
as close as possible to the pneumatic circular
saw.
Set the operating pressure on the filter
pressure reducer to max. 8 bar.
You can purchase a suitable filter pressure
reducer on request from our sales department
at Schmid & Wezel.
4.2.3
Spring balancer
The machine must always be operated in
combination with a weight relief system (spring
balancer). Install this with a sliding trolley
above the working area on an element
assembled higher or on the ceiling.
Information on fine adjustment of the spring
balancer is provided in Chapter 6.2.
Hang the pneumatic circular saw as top-heavy
as possible. The vertical position can be
adjusted if necessary.
Attaching or removing the weight relief may
result in a risk of the machine slipping or falling
due to weight (depending on the version
between 2.5 and 9 kg). Also make sure that
the machine is not jammed by the snap hook
