REPAIR AND CLEANING PROCEDURE
WARNING!
BEFORE STARTING ANY KIND OF MAINTENANCE OR REPAIR:
•
DISCONNECT THE COMPRESSED AIR SUPPLY AND OPEN THE VALVE TO
RELIEVE GREASE PRESSURE. THE PUMP IS ABLE TO STORE
ULTRA HIGH
PRESSURE
, SO EXTREME PRECAUTIONS MUST BE TAKEN.
•
HEAVY WEIGHT EQUIPMENT: BE SURE TO FIX THE PUMP IN A STABLE
POSITION, USING THE UPPER EYE-BOLT WITH A LIFTER OR SOME STRONG
GRIPPING DEVICE (I.E. A VISE).
!
SEPARATE THE AIR MOTOR FROM THE PUMP (FIG. 4)
1.
Use some kind of lifter/support to manipulate and place the pump
in a vertical and stable position. For instance, both upper eye-bolts
(1) for lifting/hanging the motor and a vise for gripping the body/
tube (63/74) can be used.
2.
Take away both protective shields (46) by their bolts (90).
3.
Ensure the grease oulet valve is open, connect air and carefully
increase the pressure just until the pump starts to cycle in order to
get the connecting nut (50) a middle to low position of the stroke.
Now disconnect the air and make sure the pump is discharged,
with no internal pressure (grease outlet open).
4.
Unscrew the 4 bolts (62).
5.
Now the connecting nut (50) can be unscrewed from the lower
rod by spinning the whole motor counterclockwise. Warning! The
lowers get now free from the motor, so make sure the pump tube
is supported/fixed prior to separating the motor.
CLEAN THE MUFFLER (FIG. 5)
AIR DISTRIBUTOR (FIG. 6)
1.
Unscrew the bolts (14) and remove the cap (15).
2.
Ensuring the screws (24) remain into the muffler (22), unscrew
them and take away the muffler. Take away the o-ring (21).
3.
Strike gently with a plastic tool through exhaust side of
the motor to remove the spool valve (18).
4.
Replace the spool (18) by a new one with its seals factory
installed (kit 539006). This is strongly recommended in
order to ensure the correct assembly of the seals.
