c. For flat-pulley drive systems, verify allowable
distance of belt from edge of pulley. Refer to
Table 1 below.
d. For F and variable-speed models only,
verify that V-belts are properly tensioned by
applying a set force to the belts and measuring
the deflection to determine the belt tension.
Refer to Table 2 for the acceptable belt’s
tension ranges. Belt tension measurements
should be taken as close to the center of the
belt span as possible. Refer to Figure 8.

2. For 80 and 125 pound capacity models only,
lubricate bearings and seals each month OR after
every 200 hours of operation.
a. Use a premium-grade lithium-based #2
grease. Never mix two types of grease, such
as petroleum and silicone.
b. Pump the grease gun slowly, permitting only
the following number of strokes:
• Bearing grease fitting, 2 strokes
• Seal grease fitting, 2 stroke
NOTE: Do not pump the grease gun until grease
comes out of the bearing housing. This can result in
overlubrication, causing damage to bearings and
seals.
3. Remove back panel and check overflow hose and
drain hose for leaks.
4. Unlock and remove the top cover and check the
supply dispenser hoses and hose connections.
5. Clean inlet hose filter screens:
a. Turn water off and allow valve to cool, if
necessary.
b. Unscrew inlet hose and remove filter screen.
c. Clean with soapy water and reinstall. Replace
if worn or damaged.
6. Tighten motor mounting bolt locknuts and
bearing bolt locknuts. Check to see that the pin is
in place.
