Replacing / adjusting the belt
NOTE:
The toothed belt system does not require any adjust-
ment. If the upper pulley is placed on the motor shaft, it
should be pushed as far as its stop. Loctite should then
be applied to the adjusting screws. The lower pulley is
placed on the gear unit and secured in place with a fea-
ther key groove and a retaining ring. The flange on the
upper pulley holds the belt in the correct position and the
belt aligns itself with the lower pulley. No specific work
is therefore required here.
1. Remove the cover from the device.
2. Dismantle the clamping device. Loosen the screws.
Slide the gear unit forwards in order to be able to
disassemble and replace the belt.
3. Tighten the screws of the gear unit as far as possible.
Doing this will ensure it is properly aligned.
4. Reinsert the clamping device and the screws; when
doing this leave the screws slack so that you are able
to adjust the tension of the belt.
5. Tension the belt. When the belt has been tensioned
properly its deflection should be 6.4 mm (1/4 inch)
when pressed hard with your thumb. (27 Nm or 20
ft/lbs).
NOTE:
When placing the belt onto the pulleys and when inser-
ting the clamping device against the belt, make sure that
the teeth of the belt engage in the teeth of the pulleys
before starting to tension the belt. If you turn the upper
pulley while pressing the clamping device firmly against
the belt, you will be able to align the teeth properly
before tensioning the belt.
Original instruction
Servicing the fluid pump
NOTE:
Before disassembling the sprayer please read through the
troubleshooting section first; one of the proposed solu-
tions there may help you to remedy the problem.
Disconnecting the fluid pump
1. If possible, flush the spray material from the device.
2. Relieve the pressure (see chapter 4). Hold the pump
at mid stroke.
3. Remove the suction pipe and the fluid hose (if pre-
sent) from the fluid pump.
4. Remove the connecting rod cover from the pump.
5. Remove the two retaining rings, slide the sleeve of
the coupling downwards and dismantle the two hal-
ves of the coupling. The fluid pump is now discon-
nected from the connecting rod.
6. Loosen the high-pressure fluid pipe from the pump by
using a 7/8 inch wrench.
7. Unscrew the locking nuts from the two connecting
rods by using a 9/16 inch wrench.
8. Pull the pump from the connecting rods.
