Disposal And Recycling - Stanley B 251/10/50 Manual De Instrucciones

unscrew the oil drainage screw (ref. 15) from the com-
pressor pump. To prevent the oil from running out in an
uncontrolled manner, hold a small metal chute under
the opening and collect the oil in a vessel. If the oil
does not drain out completely, we recommend tilting
the compressor slightly.
Dispose of the old oil at a drop-off point for old oil.
When the oil has drained out, re-fit the oil drainage
screw (ref. 15). Fill new oil through the oil filler opening
(ref. 14) until it comes up to the required level. Then
replace the oil sealing plug (ref. 14).
6.6 Retensioning the V-belt (Figs.13-15)
● Pull out the power plug and remove the safety guard
for the V-belt.
● Slacken the four motor fixing screws (A).
● Shift the motor until the V-belt is tensioned to the
point where it can still be depressed by approx. 1-2
cm at the longest free position.
● Retighten the motor fixing screws (A) and refit the
safety guard for the V-belt.
6.7 Tightening of head tension rods
● Check that all screws (in particular those of the head
of the unit) are tightly drawn up (fig. 24).
● The check must be carried out prior to the first com-
pressor starting.

CAUSE
Check valve does not perform its
function correctly due to wear or
dirt on the seal.
Condensate drainage cock open.
Rilsan hose not inserted correctly
in pressure switch.
Excessively high consumption.
Leaks from joints and/or pipes.
Clogging of the suction filter.
Slipping of the belt.

Screw M14
6.8 Cleaning the intake filter (ref. 1)
The intake filter prevents dust and dirt being drawn in.
It is essential to clean this filter after at least every 100
hours in service. A clogged intake filter will decrease the
compressor's performance dramatically. Undo the two
Allen screws (B). You can then remove the filter from
the two halves of the plastic housing, tap it to remove
the dirt, blast it down with low-pressure compressed
air (approx. 3 bar) and re-insert it (Figures 16-17-18).
6.9 Storage
Warning!
Pull the mains plug out of the socket and ventilate
the appliance and all connected pneumatic tools.
Switch off the compressor and make sure that it is
secured in such a way that it cannot be started up
again by any unauthorized person.
Warning!
Store the compressor only in a dry location which
is not accessible to unauthorized persons. Always
store upright, never tilted!

7. DISPOSAL AND RECYCLING

The unit and its accessories are made of various types
of material, such as metal and plastic. Defective com-
ponents must be disposed of as special waste. Ask
your dealer or your local council.
Unscrew the hex-shaped head of the check
valve, clean the housing and the special
rubber disk (replace if worn). Re-assembler
and tighten carefully (fig. 21-22).
Close the condensate drainage cock.
Insert the Rilsan hose correctly inside the
pressure switch.
Decrease the demand of compressed air.
Change gaskets.
Clean/replace the suction filter (fig. 16-17-18).
Check belt tension (fig. 15).
