MAINTENANCE

5. Check the pressing shoes for wear or damage

and replace them if necessary. Refer to § 8.7.2.

Also see the maintenance scheme in § 8.2.

6. Replace the cover and fasten the retaining bolts

with the correct torque. Refer to § 11.1.6.

7. Switch on the electrical supply to the pump.

8.6.3 Fitting the pump hose

1. Clean the (new) pump hose on the outside and

fully lubricate it with Bredel Genuine Hose

Lubricant.

2. Fit the pump hose (A) via one of the ports.

3. Let the motor run to draw the hose in the pump

housing. The rotor will move the hose. Stop the

motor when the hose protrudes out equally from

both sides of the pump housing.

CAUTION

When the pressing shoes are worn the

compression force of the hose decreases.

If the compression force is too low, this

results in a loss of capacity by the backflow

of the liquid to be pumped.

Backflow results in a reduction of the life of

the pump hose.

WARNING

During jogging the drive:

- Do not stand in front of the pump

ports.

- Do not try to guide the hose by

hand.
