Replacing a Worn Hose
Remove Old Hose
1. Turn off and lock out all power to pump motor.
2. Remove front cover from pump (four screws).
3. See Figure 9. Position rotor as shown.
Install New Hose
1. Check for correct length of hose:
Model 2006: 45 1/4 in. (1150 mm)
Model 2007: 57 1/4 in. (1455 mm)
2. Install connectors in new hose.
3. Position bent hose inside pump casing.
4. Push upper connector against end of pump casing. Install
top clamp and secure clamp bolt.
5. Repeat Step 4 on the lower connection.
Important:
On models 2006
and 2007, allow a 1-1.5 mm gap
between the hose and the inside
of the pump casing at Point A as
shown in the illustration at right.
6. Smear non-petroleum silicone grease on inner surface of
hose (where rollers contact hose).
7. Turn the rotor 180°. Reinstall the roller holder without shims.
8. Set roller pressure according to procedure following
(steps 3 thru 7).
5. See Figure 11. Loosen clamp bolts. Remove hose supports
and clamps that secure both ends of hose.
6. Remove hose from pump casing.
7. Pull (cut hose if needed) hose connectors from worn hose.

Also remove any shims under it.
5. See Figure 10. Turn rotor 180° as shown.
Setting Roller Pressure
Note: The pressure setting must be checked when a new hose
is installed, because of variations in hose thickness.
1. Remove front cover from pump (four screws).
2. Remove any shims under two roller holders.
3. Be sure bolts securing roller holders are tight.
4. See Figure 12. Start pump. Place palm of hand over suction
opening and check for vacuum.
a. If there is vacuum on first attempt, rollers are set.
b. If not enough vacuum, gradually add 0.5 mm (.02 in.) shims
under one of rollers and repeat test until suction seems to
be correct.
Do not install more than four shims
under
each roller.
5. Add same number of shims under other roller.
6. Test pump in full operation, and readjust as necessary.
7. Reattach front cover.
