Maintenance

WARNING
Before starting work on any of the
systems, make sure that there is no
pressure in the air system and
cooling system. High pressure air
can escape, with the risk of injury to
the eyes and skin.
CAUTION
Check that the compressed-air hose
is connected to the machine correct-
ly. If not, the hose can come loose
and whip around dangerously, with
the risk of injury to personnel.

Normal care
Blow the machine clean and fill with a
little oil at the end of each shift. Clean
the strainer 68 regularly so that it does
not restrict the air supply to the machine.
Thorough servicing and inspection of the
machine should be carried out after
every 500 hours of operation, or once
every 6 months.
Lubrication
The motor should be lubricated by
atomized oil in the compressed air. The
best way to achieve this is to connect an
oil-mist lubricator into the air line. The
lubricator should be located at the same
height or higher than the grinding
machine, no more than 7 meters away
from the machine. Otherwise, it is
recommended that a lubricator (ordering
No. 9500-2750) is connected into the
throttle handle of the machine. Before
starting the machine each day, check that
the lubricator is full of oil.

The throttle and ball bearing should be
greased during regular maintenance of
the machine.
The ball bearing 14 must be greased via
the grease nipple 19 after every 20 hours
of operation. The recommended quantity
of grease is 1 cm
tered by approx. 4 strokes of the grease
gun 9500-2739 (standard).
Use lubricants of good quality. See the
list of recommended lubricants.
Maintenance
The strainer 68 at the air connection
should be cleaned frequently so as not to
restrict the air supply and cause the
machine to operate with reduced power.
When using water flushing, the O-ring
25 should be changed regularly. If there
is an obvious flow of water through the
drainage hole 47 in the upper part of the
machine, change the seal rings 37 and O-
rings 36 and 38.
The machine should be stripped for
thorough cleaning and inspection every 6
months. If the machine is in daily use,
this should be carried out after every 3
months of operation.
Flushing air
The Grind Matic HG is delivered
equipped for air flushing. Flushing air is
taken directly from the air inlet port for
the motor. The adjustment screw 45 must
be fully tightened.
Connecting the flushing water
If the grinding cup is to be cooled with
water, the conversion kit must be fitted.
Remove the upper part of the machine
43, the screw 47, plug 53 and gasket 54.
Fit the parts 35–38 and 41–42, and fit the
locking clip 39 to the shaft 32.

Fit back the upper part 43 together with
the gasket 40. Fit the adjustable angle
connector 106 together with the hose
connection parts 107–114.
Water is connected to the machine by
means of a 6.3 mm (1/4") hose.
The water pressure must not exceed
4.5 bar (450 kPa or 4.5 kp/cm
Use cold water only.
The water flow can be regulated by
means of the adjustment screw 45.
Rust preventive measures when
using water flushing
To avoid corrosion caused by the
flushing water, it is important to do the
following:
Before fitting the grinding cup, its shaft
must be smeared with a rust-inhibiting
agent such as Shell Ensis Compound 356
or similar.
At the end of every grinding session,
blow the machine clean and lubricate
according to one of the following
methods:
1. Remove the grinding cup. Blow out
the water hose with compressed air and
then dip the chuck into a rust-inhibiting
agent.
2. Remove the grinding cup. Pour a little
oil directly into the water hose and blow
through with compressed air until oil
mist comes out of the holder 23.
