PUMP
Make sure the pump wetting cup is always filled up with T lubricant (this T lubricant will normally be
coloured by the paint).
Regularly clean the wetting cup with solvent after having drained the lubricant (unscrew the plug
located on the upper body).
If you have to change the drum :
•
Check if the plate seal is not damaged.
•
Clean top and bottom parts of the follower-plate.

TROUBLE
CAUSE
SOLUTION
The pump does not
work or stops
operating.
Air supplying.
Packings of hydraulic piston are stuck.
Reversing valve is blocked (motor)
Frosting (motor)
Nozzle is clogged.
Check air pressure.
Clean or replace.
Repair. Inject a little oil.
Defrost and lubricate using a little oil.
Clean.
The pump cycles
continuously (drain-
valve closed).
No starting up.
Empty drum.
Valve is blocked.
Increase the pressure on the
follower-plate.
Clean or replace it.
The pump piston
goes down faster
than it goes up.
Leakage from the suction valve.
Clean it.
The pump piston
goes up faster than
it goes down.
Leakage from the exhaust valve.
Clean it.
The pump piston
goes down rapidly
half-way, then resu-
mes normal speed.
Pump unproperly drained.
Leakage from the suction valve.
Open the drain valve (or press the
gun trigger) until material starts
coming out regularly. Then close the
drain valve (or release the trigger).
Check the suction valve.
The pump operates
but provides an irre-
gular flow rate.
Air in the chamber.
Bad tightness of the valves.
Drain rod no tight enough.
Pressure on the follower plate too
low.
Check the fittings.
Clean them.
Tighten it.
Increase the pressure.
