Install New Hose
1. Check for correct length of hose:
Model 2002: 13 in. (330 mm)
Model 2003: 15 3/8 in. (390 mm)
Model 2004: 23 1/4 in. (590 mm)
Model 2005: 33 7/8 in. (860 mm)
2. Install connectors in new hose.
3. Make sure that pressure rollers are in same position as before.
See Remove Old Hose, Step 3.
4. Position bent hose inside pump casing.
5. Push upper connector against end of pump casing. Install
top hose clamp and secure its bolt.
6. Repeat Step 5 on lower connection.
Important:
On models 2002 through 2005, make sure the
hose lays completely against the inside of the pump casing.
7. Smear non-petroleum silicone grease on inner surface of
hose (where rollers contact hose).
8. Set roller pressure according to procedure following
(steps 2 thru 6).

Setting Roller Pressure
Note:
This pressure setting must be checked when a new hose
is installed, because of variations in hose thickness.
1. Remove front cover from pump.
2. See Figure 6. Loosen all roller bracket screws and slide both
rollers away from the hose to reduce compression on the
hose. Retighten all roller bracket screws.
4. Test pump in full operation, and readjust as necessary.
5. Reattach front cover.
a. If there is vacuum on first attempt, rollers are set.
b. See Figure 8. If not enough vacuum, gradually move rollers
forward in 1/32 to 1/8 in. (0.8 to 3.0 mm) increments and
repeat test until suction seems to be correct. (Make sure
compression is same for both rollers by measuring roller
bracket in relation to rectangular rotor block).
3. See Figure 7. Start pump. Place palm of hand over suction
opening and check for vacuum.
